refrigerant heat exchanger refrigerant controller 86 may control a
flow direction of the refrigerant such that the refrigerant flows
into the water refrigerant heat exchanger 72. On the other hand, if
the operation of the heat pump type speed heating apparatus does
not include a floor heating operation, then the water refrigerant
heat exchanger refrigerant controller 86 may control the flow of
the refrigerant such that the refrigerant bypasses the water
refrigerant heat exchanger 72.
[0068] The water refrigerant heat exchanger refrigerant controller
86 may control the refrigerant to flow into the water refrigerant

floor heating operation is not performed. The water refrigerant
heat exchanger refrigerant controller 86 may also include a second
valve that is provided in the hot water outflow flow path 54, and
the second valve is closed at the time of the floor heating
operation and is opened when the floor heating operation is not
performed.

of the refrigerant discharged from the compressor 12 for the
discharged refrigerant to pass through the hot water supply heat
exchanger 4 or bypass the hot water supply heat exchanger 4.
[0073] If the operation of the heat pump type speed heating
apparatus includes at least one of a hot water supply operation and
a floor heating operation, the refrigerant controller 6 may control
the refrigerant compressed at the compressor 12 to flow into the
hot water supply heat exchanger 4. On the other hand, if the
operation of the heat pump type speed heating apparatus includes
neither the hot water supply operation nor the floor heating
operation, the refrigerant controller 90 may control the
refrigerant compressed at the compressor 12 to bypass the hot water
supply heat exchanger 4.
[0074] The refrigerant controller 6, at the time of the hot water
supply operation, may control the refrigerant to flow into the hot
water supply heat exchanger 4.
[0075] The refrigerant controller 6, at the time of simultaneous
operation of the hot water supply and the air conditioning, may
control the first refrigerant to flow into the hot water supply
heat exchanger 4.
[0076] The refrigerant controller 6, at the time of simultaneous
operation of hot water supply and floor heating, can control the
first refrigerant to flow into the hot water supply heat exchanger
4.
[0077] The refrigerant controller 6, at the time of simultaneous
operation of hot water supply, floor heating, and air conditioning,
can control the first refrigerant to flow into the hot water supply
heat exchanger 4.
[0078] The refrigerant controller 6, at the time of air
conditioning operation, can control the refrigerant to bypass the
hot water supply heat exchanger 4. In other words, the refrigerant
controller 6 can control the refrigerant to bypass the hot water
supply heat exchanger 4 at the time of a space cooling operation
and can control the refrigerant to bypass the hot water supply heat
exchanger 4 at the time of a space heating operation.
[0079] The refrigerant controller 6 can be composed of a three-way
valve that is provided in the cooling cycle circuit 2 and can
select the outflow direction of the refrigerant.
[0080] If the refrigerant controller 6 is a three-way valve, an
inlet port and a first outlet port thereof can be connected to a
compressor outflow flow path 26 and a second outlet port can be
connected to the hot water supply inflow flow path 52.
[0081] The heat exchanger bypass flow path 8 can be connected to
guide the refrigerant that has passed the hot water supply heat
exchanger 4 between the outdoor heat exchanger 14 and the indoor
heat exchanger 18 for the refrigerant that has passed the hot water
heat exchanger 4 to bypass either of the outdoor heat exchanger 14
and the indoor heat exchanger 18.
[0082] One end of the heat exchanger bypass flow path 8 can be
connected to the hot water supply flow path 50 and the other end of
the heat exchanger bypass flow path 8 can be connected between the
indoor expansion apparatus 17 and the outdoor expansion apparatus
16.
[0083] The heat exchanger bypass flow path 8 can guide the
refrigerant of the hot water outflow flow path 54 between the
indoor expansion apparatus 17 and the outdoor expansion apparatus
16 as one end of the heat exchanger bypass flow path 8 is connected
to the hot water outflow flow path 54 of the hot water flow path 50
and the other end of the heat exchanger bypass flow path 8 is
connected to an expansion apparatus connecting pipe 36.
[0084] The refrigerant guided to the heat exchanger bypass flow
path 8 is expanded in the indoor expansion apparatus 17 and can be
recovered by the compressor 12 after being evaporated, or the
refrigerant is expanded in the outdoor expansion apparatus 16 and
can be recovered by the compressor 12 after being evaporated at the
outdoor heat exchanger 14.
[0085] In other words, if the refrigerant is guided between the
indoor expansion apparatus 17 and the outdoor expansion apparatus
16 through the heat exchanger bypass flow path 8, a condensation
process is not generated but only an expansion and an evaporation
process are generated in the cooling cycle circuit 2, the amount of
heat transferred of the hot water supply heat exchanger 4 and the
water refrigerant heat exchanger 72 is increased, and an efficiency
of hot water supply and floor heating is enhanced.
[0086] The auxiliary refrigerant controller 10 can control the flow
direction of the refrigerant that has passed the hot water supply
heat exchanger 4 for the refrigerant that has passed the hot water
supply heat exchanger 4 to pass through the heat exchanger bypass
flow path 8 or bypass the heat exchanger bypass flow path 8.
[0087] If the operation of the heat pump type speed heating
apparatus includes both a hot water supply and an air conditioning,
the auxiliary refrigerant controller 10 may control the refrigerant
that has passed the hot water supply heat exchanger 4 to bypass the
heat exchanger bypass flow path 8.

simultaneous operation of the hot water supply and the air
conditioning.
[0089] The auxiliary refrigerant controller 10 may control the
refrigerant that has passed the hot water supply heat exchanger 4

refrigerant that has passed the hot water supply heat exchanger 4
to bypass the heat exchanger bypass flow path 8 at the time of
operation of the air conditioning.

to bypass the heat exchanger bypass flow path 8 at the time of
operation of the hot water supply.
[0092] The auxiliary refrigerant controller 10 may control the
refrigerant that has passed the hot water supply heat exchanger 4
to bypass the heat exchanger bypass flow path 8 at the time of
simultaneous operation of the hot water supply and the floor
heating.
[0093] The auxiliary refrigerant controller 10 may control the
refrigerant that has passed the hot water supply heat exchanger 4
to bypass the heat exchanger bypass flow path 8 at the time of
operation of the floor heating.
[0094] If defrosting conditions occur during the hot water supply
operation, the auxiliary refrigerant controller 10 may control the
refrigerant that has passed the hot water supply heat exchanger 4
to bypass the heat exchanger bypass flow path 8, and at this time,
the cooling cycle circuit 2 may be switched from the heating
operation to the cooling operation for defrost of the outdoor heat
exchanger 14. Defrosting of the outdoor heat exchanger 14 may be
described below.
[0095] The auxiliary refrigerant controller 10 may include a
three-way valve installed at the hot water supply outflow flow path
54 to select an outflow direction of the refrigerant.
[0096] If the auxiliary refrigerant controller 10 is a three-way
valve, then an inlet port and a first outlet port thereof can be
connected to the hot water supply outflow flow path 54 and a second
outlet port can be connected to the heat exchanger bypass flow path
8.
[0097] The auxiliary refrigerant controller 10 may include a first
valve that is provided between the auxiliary refrigerant controller
10 and the cooling/heating switching valve 40 in the hot water
supply outflow flow path 54. The first valve may be opened when the
hot water supply operation and the air conditioning operation are
performed or when the floor heating operation and the air
conditioning operation are performed. The first valve may be closed
when at least one of the floor heating operation and the hot water
supply operation are performed although the air conditioning
operation is not performed. The auxiliary refrigerant controller 10
may also include a second valve that is provided in the heat
exchanger bypass flow path 8. The second valve may be closed when
the hot water supply operation and the air conditioning operation
are performed, or the floor heating operation and the air
conditioning operation are performed. The second valve may be

water supply operation are performed although the air conditioning
operation is not performed.

include a heat exchanger bypass valve 88 provided in the heat
exchanger bypass flow path 8 for controlling the flow of the
refrigerant, and a liquid refrigerant valve 90 provided between the

[0108] The refrigerant compressed at the compressor 12 at the time
of operating the compressor 12 may pass through the refrigerant
controller 6 and flow into the cooling/heating switching valve 40
by bypassing the hot water supply heat exchanger 4 and the water
refrigerant heat exchanger 72. Afterwards, the refrigerant may be
condensed at the outdoor heat exchanger 14 by exchanging heat with
outdoor air. The refrigerant condensed at the outdoor heat
exchanger 14 may expand by at least one of the outdoor expansion
apparatus 16 and the indoor expansion apparatus 17, and the
refrigerant may evaporate at the indoor heat exchanger 18. The
refrigerant evaporated at the indoor heat exchanger 18 may be

heat exchanger 4 through the hot water pipe 58 and pass through the
hot water supply heat exchanger 4, and then circulate to the hot
water supply tank 56.
[0129] At the time of operation of the compressor 12, the
refrigerant compressed at the compressor 12 passes through the
refrigerant controller 6 and the hot water supply inflow flow path
52 and flows into the hot water supply heat exchanger 4. The
refrigerant heated at the compressor 12 may be condensed by
exchanging heat with water while the refrigerant passes through the
hot water supply heat exchanger 4. The refrigerant condensed at the
hot water supply heat exchanger 4 may bypass the water refrigerant
heat exchanger 72 while passing through the hot water supply
outflow flow path 54 and passing through the auxiliary refrigerant
controller 10 and flow into the cooling/heating switching valve 40.
The refrigerant may be condensed again at the indoor heat exchanger
18 by exchanging heat with indoor air. The refrigerant condensed at
the indoor heat exchanger 18 may expand in at least one of the
outdoor expansion apparatus 16 and the indoor expansion apparatus
17, and the refrigerant may evaporate at the outdoor heat exchanger
14. The refrigerant may be recovered by the compressor 12 as the
refrigerant evaporated at the outdoor heat exchanger 14 passes

[0133] FIG. 7 is a block diagram illustrating a flow of a
refrigerant when the heat pump type speed heating apparatus (FIG.
2) is in a floor heating operation. Other embodiments and
configurations may also be provided.
[0134] In the example of a floor heating operation, the heat pump
type speed heating apparatus may operate as follows. The compressor
12 may be operated. The refrigerant controller 6 may be controlled
for the refrigerant to flow into the hot water supply heat
exchanger 4. The water refrigerant heat exchanger refrigerant
controller 86 may be controlled for the refrigerant of the hot

52 and flow into the hot water supply heat exchanger 4. The
refrigerant may pass the hot water supply heat exchanger 4 without

heating inflow flow path 74 and may be condensed by exchanging heat
with water while passing through the water refrigerant heat
exchanger 72. The refrigerant condensed at the water refrigerant
heat exchanger 72 may flow into the hot water supply outflow flow
path 54 through the heating inflow flow path 76, and the

refrigerant that has flowed into the heat exchanger bypass flow
path 8 may expand at the outdoor expansion apparatus 16 after
passing through the heat exchanger bypass valve 88 and may
evaporate at the outdoor heat exchanger 14 by exchanging heat with
outdoor air. The refrigerant evaporated at the outdoor heat

time of a floor heating operation. The water temperature of the
floor heating pipe 80 may increase more quickly than an example
where the refrigerant passes through the indoor heat exchanger 18
or the hot water pump 60 is operated.
[0140] FIG. 8 is a block diagram illustrating a flow of a
refrigerant when the heat pump type speed heating apparatus (FIG.
2) is in both a floor heating operation and a hot water supply
operation. Other embodiments and configurations may also be
provided.
[0141] In an example of simultaneous operation of a floor heating
and a hot water supply, the heat pump type speed heating apparatus
may operate as follows. The compressor 12 may be operated. The
refrigerant controller 6 may be controlled for the refrigerant to
flow into the hot water supply heat exchanger 4. The water
refrigerant heat exchanger refrigerant controller 86 may be
controlled for the refrigerant of the hot water supply outflow flow
path 54 to pass through the water refrigerant heat exchanger 72.

[0142] At the time of operating the hot water pump 60, the water of
the hot water supply tank 56 may flow into the hot water supply
heat exchanger 4 through the hot water pipe 58 and pass through the
hot water supply heat exchanger 4 and then circulate to the hot

[0143] The water of the floor heating pipe 80, at the time of
operating the floor heating pump 84, may flow into the water
refrigerant heat exchanger 72 through the heating water pipe 82 and
may pass through the water refrigerant heat exchanger 72 and then
circulate to the floor heating pipe 80.
[0144] At the time of operating the compressor 12, the refrigerant
compressed at the compressor 12 may flow into the hot water supply
heat exchanger 4 after passing through the refrigerant controller 6
and the hot water supply inflow flow path 52. The refrigerant
overheated at the compressor 12 while passing through the hot water
supply heat exchanger 4 may be condensed by exchanging heat with
water. The refrigerant condensed at the hot water supply heat
exchanger 4 may flow into the water refrigerant heat exchanger
refrigerant controller 86 and flow into the water refrigerant heat
exchanger 72 through the heating inflow flow path 74, and the
refrigerant may be condensed again by exchanging heat with water
while passing through the water refrigerant heat exchanger 72. The
refrigerant condensed at the water refrigerant heat exchanger 72
may flow into the hot water supply outflow flow path 54 through the

path 88. The refrigerant may evaporate at the outdoor heat
exchanger 14 by exchanging heat with outdoor air. The refrigerant
evaporated at the outdoor heat exchanger 14 may be recovered by the
compressor 12 after passing through the cooling/heating switching
valve 40.
[0145] The refrigerant discharged at the compressor 12 may be
recovered by the compressor 12 after sequentially passing through
the hot water supply heat exchanger 4, the water refrigerant heat
exchanger 72, the heat exchanger bypass flow path 8, the outdoor
expansion apparatus 16, the outdoor heat exchanger 14, and the
cooling/heating switching valve 40.
[0146] The hot water supply heat exchanger 4 and the water
refrigerant heat exchanger 72 may condense the refrigerant
sequentially The outdoor heat exchanger 14 may evaporate the
refrigerant. The hot water supply heat exchanger 4 may heat the
water of the hot water supply tank 56. The water refrigerant heat
exchanger 72 may heat the water of the floor heating pipe 80.
[0147] The heat pump type speed heating apparatus may use the
refrigerant to heat the water of the hot water supply tank 56 and
the floor heating pipe 80 at the time of simultaneous operation of
the floor heating and the hot water supply. Therefore, the water
temperature of the hot water supply tank 56 and the floor heating
pipe 80 can be increased more quickly than an example where the
refrigerant passes through the indoor heat exchanger 18.
[0148] FIG. 9 is a block diagram illustrating a flow of a
refrigerant when a heat pump type speed heating apparatus (FIG. 2)
is in a hot water supply operation. Other embodiments and

outdoor fan 30 may be rotated, and the indoor fan 39 may not be
rotated. The cooling/heating switching valve 40 may operate in a
heating mode. The heat exchanger bypass valve 88 may be opened, and
the liquid refrigerant valve 90 may be closed. The hot water pump
60 may be operated, and the floor heating pump 84 may not be
operated.
[0150] At the time of operating the hot water pump 60, the water of
the hot water supply tank 56 may flow into the hot water supply
heat exchanger 4 through the hot water pipe 58. The water of the
hot water supply tank 4 may then pass through the hot water supply
heat exchanger 4 and may be circulated to the hot water supply tank
56.
[0151] At the time of operating the compressor 12, the refrigerant
compressed at the compressor 12 may flow into the hot water supply
heat exchanger 4 after passing through the refrigerant controller 6
and the hot water supply inflow flow path 52. The refrigerant
overheated at the compressor 12 while passing through the hot water
supply heat exchanger 4 may be condensed by exchanging heat with
water. The refrigerant condensed at the hot water supply heat
exchanger 4 flows into the water refrigerant heat exchanger
refrigerant controller 86 and bypasses the water refrigerant heat
exchanger 72 and flows into the auxiliary refrigerant controller
10. The refrigerant that has flowed into the auxiliary refrigerant
controller 10 flows into the heat exchanger bypass flow path 8 and
may be expanded at the outdoor expansion apparatus 16 after passing
through the heat exchanger bypass valve 88. The refrigerant
expanded in the outdoor expansion apparatus 16 may be evaporated in
the outdoor heat exchanger 14 by exchanging heat with outdoor air
and may be recovered by the compressor 12 after passing through the
cooling/heating switching valve 40.
[0152] The refrigerant discharged from the compressor 12 is
recovered by the compressor 12 after sequentially passing through
the hot water supply heat exchanger 4, the heat exchanger bypass
flow path 8, the outdoor expansion apparatus 16, the outdoor heat
exchanger 14, and the cooling/heating switching valve 40.
[0153] The hot water supply heat exchanger 4 may condense the
refrigerant. The outdoor heat exchanger 14 may evaporate the
refrigerant. The hot water supply heat exchanger 4 may heat the
water of the hot water supply tank 56.
[0154] The heat pump type speed heating apparatus may use the
refrigerant to heat the water of the hot water supply tank 56 at
the time of hot water supply operation. Therefore, water
temperature of the hot water supply tank 56 may be raised more
quickly than an example where the refrigerant passes through the
indoor heat exchanger 18.
[0155] FIG. 10 is a block diagram illustrating a flow of a
refrigerant when the heat pump type speed heating apparatus (FIG.
9) is in a defrosting operation in a middle of hot water supply
operation. Other embodiments and configurations may also be
provided.
[0156] Since the outdoor heat exchanger 14 functions as an
evaporator at a time of operation of a hot water supply, a frost
can be developed at the outdoor heat exchanger 14. If defrosting
conditions are met for the outdoor heat exchanger 14, the outdoor
heat exchanger 14 may be switched to defrost while the heat pump
type speed heating apparatus continues a hot water supply
operation.
[0157] The heat pump type speed heating apparatus may control the
auxiliary refrigerant controller 10 for the refrigerant that has
passed the hot water supply heat exchanger 4 to bypass the heat
exchanger bypass flow path 8 and that switches the cooling cycle
circuit 2 from a heating operation to a cooling operation.
[0158] The defrosting conditions are such that accumulated time of
the hot water supply operation is a predetermined time or more. The
temperature of the outdoor heat exchanger 14 is a predetermined
temperature or less for a predetermined time period or more.
[0159] The auxiliary refrigerant controller 10 may control the
refrigerant to flow into the cooling/heating switching valve 40
during a hot water supply operation. The cooling/heating switching
valve 40 may operate in a cooling mode. The liquid refrigerant
valve 90 may be opened, and the heat exchanger bypass valve 88 may
be closed.
[0160] The refrigerant condensed while passing through the hot
water supply heat exchanger 4 after being compressed by the
compressor 12 may bypass the heat exchanger bypass flow path 8 as
the refrigerant passes through the auxiliary refrigerant controller
10 and flow into the cooling/heating switching valve 40. The
refrigerant that has passed the cooling/heating switching valve 40
flows into the outdoor heat exchanger 14 and is condensed again
while defrosting the outdoor heat exchanger 14. Afterwards, the
first refrigerant expands as the first refrigerant passes through
at least one of the outdoor expansion apparatus 16 and the indoor
expansion apparatus 17 and may be evaporated as the first
refrigerant passes through the indoor heat exchanger 18. The
refrigerant evaporated at the indoor heat exchanger 18 passes
through the cooling/heating switching valve 40 and is recovered by
the compressor 12.
[0161] The refrigerant discharged from the compressor 12 is
recovered by the compressor 12 after sequentially passing through
the hot water supply heat exchanger 4, the cooling/heating
switching valve 40, the outdoor heat exchanger 14, the outdoor
expansion apparatus 16, the indoor expansion apparatus 17, the
indoor heat exchanger 18, and the cooling/heating switching valve
40.
[0162] The heat pump type speed heating apparatus may be defrosted
as the hot water supply heat exchanger 4 condenses the refrigerant
and the outdoor heat exchanger 14 condenses the refrigerant again,
and the hot water supply heat exchanger 4 heats the water of the
hot water supply tank 56.
[0163] Since the outdoor heat exchanger 14 is defrosted as the
refrigerant continuously heats the water of the hot water supply
tank 56 at the time of hot water supply operation of the heat pump
type speed heating apparatus, a water temperature of the hot water
supply tank 56 may increase more quickly and efficiency of hot
water supply is enhanced.
[0164] FIG. 11 is a block diagram illustrating a flow of a
refrigerant when the heat pump type speed heating apparatus (FIG.
2) is in a space heating, floor heating, and hot water supply
operation. Other embodiments and configurations may also be
provided.
[0165] In an example of simultaneous operation of space heating,
floor heating and hot water supply, the heat pump type speed
heating apparatus may operate as follows. The compressor 12 may be
operated. The refrigerant controller 6 may be controlled for the
refrigerant to flow into the hot water supply heat exchanger 4. The
water refrigerant heat exchanger refrigerant controller 86 may be
controlled for the refrigerant of the hot water supply outflow flow
path 54 to pass through the water refrigerant heat exchanger 72.
The auxiliary refrigerant controller 10 may be controlled for the
refrigerant of the hot water supply outflow flow path 54 to bypass
the heat exchanger bypass flow path 8. The outdoor fan 30 may be
rotated, and the indoor fan 39 may be rotated. The cooling/heating
switching valve 40 may operate in a heating mode. The heat
exchanger bypass valve 88 may be closed, the liquid refrigerant
valve 90 may be opened. The hot water pump 60 may be operated, and
the floor heating pump 84 may be operated.
[0166] At the time of operating the hot water pump 60, the water of
the hot water supply tank 56 may flow into the hot water supply
heat exchanger 4 through the hot water pipe 58 and may be
circulated to the hot water supply tank 56 after passing through
the hot water supply heat exchanger 4.
[0167] At the time of operating the floor heating pump 84, the
water of the floor heating pipe 80 may flow into the water
refrigerant heat exchanger 72 through the heating water pipe 82 and
may be circulated to the floor heating pipe 80 after passing
through the water refrigerant heat exchanger 72.
[0168] At the time of operating the compressor 12, the refrigerant
compressed at the compressor 12 may flow into the hot water supply
heat exchanger 4 after passing through the refrigerant controller 6
and the hot water supply inflow flow path 52. The refrigerant
overheated at the compressor 12 while passing through the hot water
supply heat exchanger 4 may be condensed by exchanging heat with
water. The refrigerant condensed at the hot water supply heat
exchanger 4 may flow into the water refrigerant heat exchanger
refrigerant controller 86 and flow into the water refrigerant heat
exchanger 72 through the heating inflow flow path 74, and may be
condensed again by exchanging heat with water while passing through
the water refrigerant heat exchanger 72. The refrigerant condensed
at the water refrigerant heat exchanger 72 may flow into the hot
water supply outflow flow path 54 through the heating inflow flow
path 76 and then pass through the auxiliary refrigerant controller
10, flowing into the cooling/heating switching valve 40 while
bypassing the heat exchanger bypass flow path 8. The refrigerant
that has flowed into the cooling/heating switching valve 40 may
flow into the indoor heat exchanger 18 and may be additionally
condensed. The refrigerant may be expanded in at least one of the
indoor expansion apparatus 17 and the outdoor expansion apparatus
16 and may then be evaporated at the outdoor heat exchanger 14 by
exchanging heat with outdoor air. The refrigerant evaporated at the
outdoor heat exchanger 14 may be recovered by the compressor 12
after passing through the cooling/heating switching valve 40.
[0169] The refrigerant discharged from the compressor 12 may be
recovered by the compressor 12 after sequentially passing through
the hot water supply heat exchanger 4, the water refrigerant heat
exchange 72, the cooling/heating switching valve 40, the indoor
heat exchanger 18, the indoor expansion apparatus 17, the outdoor
expansion apparatus 16, the outdoor heat exchanger 14, and the
cooling/heating switching valve 40.
[0170] The hot water heat exchanger 4, the water refrigerant heat
exchanger 72, and the indoor heat exchanger 18 may condense the
refrigerant sequentially for three times in total. The outdoor heat
exchanger 14 may evaporate the refrigerant. The hot water supply
heat exchanger 4 may heat the water of the hot water supply tank
56. The water refrigerant heat exchanger 72 may heat the water of
the floor heating pipe 80.
[0171] At the time of simultaneous operation of floor heating, hot
water supply, and space heating, the refrigerant may be used to
heat the water of the hot water supply tank 56, the water of the
floor heating pipe 80, and the indoor air together. Therefore, the
heat pump type speed heating apparatus may efficiently perform hot
water supply, floor heating, and space heating.
[0172] FIG. 12 is a block diagram of an embodiment of a heat pump
type speed heating apparatus according to an embodiment of the
present invention. Other embodiments and configurations may also be
provided.
[0173] The heat pump type speed heating apparatus may include a
multi-stage compressor where the compressor 12 compresses the
refrigerant in multi-steps.
[0174] The compressor 12 can include a low pressure side
compression unit 12a and a high pressure compression unit 12b
connected to the low pressure compression unit 12a to compress the
refrigerant compressed at the low pressure compression unit
12a.
[0175] The low pressure compression unit 12a and the high pressure
compression unit 12b may be connected to each other in series. An
inflow flow path 22 of the compressor 12 may be connected to the
low pressure compression unit 12a and a discharge flow path 26 of
the compressor may be connected to the high pressure compression
unit 12b.
[0176] A gas-liquid separator 100 can be provided between the
outdoor expansion apparatus 16 and the indoor expansion apparatus
17 of the heat pump type speed heating apparatus. An injection line
102 that injects a vaporized refrigerant by using the compressor 12
may be connected to the gas-liquid separator 100.
[0177] The gas-liquid separator 100 can be provided between the
heat exchanger bypath flow path 8 and the outdoor expansion
apparatus 16 to inject the vaporized refrigerant to the compressor
12 at the time of simultaneous operation of hot water supply and
heating, hot water supply operation, and/or heating operation.
[0178] An injection refrigerant controller 104 may be provided at
the injection line 102 to control the refrigerant that is injected
into the compressor 12.
[0179] The injection refrigerant controller 104 may control the
vaporized refrigerant that has flowed out from the gas-liquid
separator 100. The injection refrigerant controller 104 may include
an opening and closing valve whose opening and closing is
controlled by on-off control. The injection refrigerant controller
104 may also include an electronic expansion valve whose opening
angle is controlled.
[0180] The injection refrigerant controller 104 may be closed at
the time of a starting operation of the heat pump type speed
heating apparatus and may be opened after stabilization of the heat
pump type speed heating apparatus according to a temperature of the
outdoor heat exchanger 14.
[0181] A temperature sensor 108 that senses a temperature can be
provided at the outdoor heat exchanger 14 and the injection
refrigerant controller 104 can be opened if the sensed temperature
of the temperature sensor 108 is a predetermined temperature or
less after stabilization of the heat pump type speed heating
apparatus.
[0182] The heat pump type speed heating apparatus may include an
electronic expansion valve that lowers the pressure of the
refrigerant injected to the injection line 102 to an intermediate
pressure between a condensation pressure of the hot water supply
heat exchanger 4 and an evaporation pressure of the outdoor heat
exchanger 14 while preventing the liquid refrigerant inside the
gas-liquid separator 100 from flowing into the injection line 102
at the time of simultaneous operation of hot water supply and
heating, hot water supply operation, and/or heating operation.
[0183] The electronic expansion valve may be provided between the
auxiliary refrigerant controller 10 and the gas-liquid separator
100. The electronic expansion valve may be provided between the
heat exchanger bypass valve 88 and the gas-liquid separator 100.
The electronic expansion valve may also be provided between the
auxiliary refrigerant controller 10 and the heat exchanger bypass
valve 88.
[0184] If the heat exchanger bypass valve 88 includes an electronic
expansion valve, at the time of simultaneous operation of hot water
supply and floor heating, hot water supply operation, or floor
heating operation, a pressure of the refrigerant that passes
through the heat exchanger bypass flow path 8 is lowered to an
intermediate pressure between a condensation pressure and an
evaporation pressure. When the heat pump type speed heating
apparatus performs a defrosting operation in a middle of a hot
water supply operation, simultaneous operation of air conditioning
and hot water supply, simultaneous operation of air conditioning,
hot water supply, and flow heating, and/or air conditioning
operation, the heat exchanger bypass valve 96 may be closed.
[0185] Since the remaining structure and functions except for the
compressor 12, the heat exchanger bypass valve 88, the gas-liquid
separator 100, the injection line 102, and the injection
refrigerant controller 104 are identical or similar to one
embodiment, the same symbols may be used and a detailed description
corresponding thereto may be omitted.
[0186] A description may be provided with an example of a hot water
supply operation.
[0187] At the time of hot water supply operation, the heat pump
type speed heating apparatus may operate as described in one
embodiment. If the outdoor heat exchanger 14 is at a predetermined
temperature or less while the heat pump type speed heating
apparatus is stabilized after starting, the heat exchanger bypass
valve 88 may expand the refrigerant to a pressure between a
condensation pressure of the hot water supply heat exchanger 4 and
an evaporation pressure of the outdoor heat exchanger 14, and the
injection refrigerant controller 104 may be opened.
[0188] At the time of refrigerant expansion of the heat exchanger
bypass valve 88 and opening of the injection refrigerant controller
88, a refrigerant with an intermediate pressure injected through
the injection line 102 may flow between the low pressure
compression unit 12a and the high pressure compression unit 12b of
the compressor 12. Therefore, a compression period may be reduced
according to injection of the refrigerant with an intermediate
pressure. Effective hot water supply may be made possible at a cold
area or at low outdoor temperature due to increase of a
condensation capacity of the hot water supply heat exchanger 4. A
highest management temperature of the compressor 12 may also be
lowered.
[0189] Even at the time of simultaneous operation of floor heating
and hot water supply or floor heating operation, a refrigerant of
an intermediate pressure may be injected to the compressor 12 and
an efficient operation may be made possible for the heat pump type
speed heating apparatus.
[0190] Embodiments of the present invention may not be limited to
the above embodiment although the heat pump type speed heating
apparatus may also be operated by at least one of air conditioning
operation and hot water supply operation without floor heating
operation and not including the water refrigerant heat exchanger
connecting flow path 70, the water refrigerant heat exchanger 72,
the check valve 78, the floor heating pipe 80, the heating water
pipe 82, the floor heating pump 84, and the water refrigerant heat
exchanger refrigerant controller 86. Various embodiments may be
possible within the technical scope to which the present invention
belongs.
[0191] The heat pump type speed heating apparatus, at the time of
hot water supply operation, may improve hot water supply
performance as the refrigerant that has passed the hot water supply
heat exchanger bypasses either of the indoor heat exchanger and the
outdoor heat exchanger. At the time of simultaneous operation of
hot water supply and air conditioning, the refrigerant that has
been condensed while heating the hot water supply heat exchanger
performs air conditioning by passing through both the indoor heat
exchanger and the outdoor heat exchanger, and thereby improving
efficiency.
[0192] Hot water supply can be provided continuously by defrosting
the outdoor heat exchanger during hot water supply operation.
[0193] At the time of hot water supply operation, as the
refrigerant at an intermediate pressure between a condensation
pressure and an evaporation pressure is injected into the
compressor, a degradation of hot water supply performance is
degraded under outdoor low temperature environments, efficiency of
hot water supply is high since condensation performance of the hot
water supply heat exchanger may be improved.
[0194] Furthermore, hot water supply, floor heating, and space air
conditioning may be performed together.
[0195] Embodiments of the present invention have been made to
provide a heat pump type speed heating apparatus with high
efficiency, where a refrigerant that has passed a hot water supply
heat exchanger can bypass either of an outdoor heat exchanger and
an indoor heat exchanger.
[0196] A heat pump type speed heating apparatus may include: a
cooling cycle circuit capable of operating air conditioning
(including a compressor, an outdoor heat exchanger, an expansion
apparatus, and an indoor heat exchanger); a hot water supply heat
exchanger connected to the cooling cycle circuit through a hot
water supply flow path for a refrigerant discharged from the
compressor to be condensed, expanded, and evaporated in the cooling
cycle circuit after being used for hot water supply; a refrigerant
controller that controls flow direction of the refrigerant
discharged from the compressor for the refrigerant discharged from
the compressor to pass through or bypass the hot water supply heat
exchanger; and a heat exchanger bypass flow path connected to guide
the refrigerant that has passed the hot water heat exchanger
between the outdoor heat exchanger and the indoor heat exchanger to
bypass either of the outdoor heat exchanger and the indoor heat
exchanger.
[0197] The refrigerant controller may be controlled so that a
refrigerant flows into the hot water supply heat exchanger at the
time of hot water supply operation or simultaneous operation of hot
water supply and air conditioning.
[0198] The refrigerant controller can be controlled so that a
refrigerant bypasses the hot water supply heat exchanger at the
time of air conditioning operation.
[0199] The heat pump type speed heating apparatus can further
include an auxiliary refrigerant controller that controls the flow
direction of the refrigerant that has passed the hot water supply
heat exchanger so that the refrigerant that has passed the hot
water supply heat exchanger can either pass through or bypass the
heat exchanger bypass flow path.
[0200] The auxiliary refrigerant controller can be controlled so
that the refrigerant flows through the heat exchanger bypass flow
path at the time of hot water supply operation.
[0201] If defrosting conditions are met during the hot water supply
operation, the auxiliary refrigerant controller can be controlled
that the refrigerant bypasses the heat exchanger bypass flow path.
The cooling cycle circuit may be switched from a heating operation
to a cooling operation.
[0202] The auxiliary refrigerant controller can be controlled such
that the refrigerant bypasses the heat exchanger bypass flow path
when hot water supply and air conditioning are operated at a same
time.
[0203] The expansion apparatus can include an indoor expansion
apparatus and an outdoor expansion apparatus. One end of the heat
exchanger bypass flow path can be connected to the hot water supply
flow path and the other end thereof can be connected between the
indoor expansion apparatus and the outdoor expansion apparatus.
[0204] The heat pump type speed heating apparatus can further
include a heat exchanger bypass valve that is installed in the heat
exchanger bypass flow path and controls the flow of a
refrigerant.
[0205] The heat pump type speed heating apparatus can further
include a liquid refrigerant valve that is installed between the
heat exchanger bypass flow path and the indoor expansion apparatus
and that controls the flow of a refrigerant.
[0206] The heat pump type speed heating apparatus can further
include a water refrigerant heat exchanger connected to the hot
water supply flow path through a water refrigerant heat exchanger
connecting flow path for the refrigerant that has passed the hot
water supply heat exchanger to flow into the hot water supply flow
path after heating water.
[0207] The heat pump type speed heating apparatus can further
include a floor heating pipe connected to the water refrigerant
heat exchanger through a heating water pipe and a floor heating
pump installed in the heating water pipe.
[0208] The heat pump type speed heating apparatus can further
include a case where the water refrigerant heat exchanger is
installed and an indoor fan that is installed inside the case and
that circulates indoor air to the water refrigerant heat
exchanger.
[0209] The heat pump type speed heating apparatus can further
include a water refrigerant heat exchanger refrigerant controller
that controls the flow direction of a refrigerant so that the
refrigerant that has passed the hot water supply heat exchanger
passes through or bypasses the water refrigerant heat
exchanger.
[0210] The water refrigerant heat exchanger refrigerant controller
may be controlled so that a refrigerant flows into a water
refrigerant heat exchanger at the time of floor heating operation,
simultaneous operation of floor heating and hot water supply, and
simultaneous operation of floor heating, hot water supply, and air
conditioning.
[0211] The refrigerant controller may be controlled so that a
refrigerant flows into the hot water supply heat exchanger at the
time of floor heating operation.
[0212] The expansion apparatus can include an indoor expansion
apparatus and an outdoor expansion apparatus. The heat pump type
speed heating apparatus may further include a gas-liquid separator
installed between the indoor expansion apparatus and the outdoor
expansion apparatus and an injection line that injects vaporized
refrigerant of the gas-liquid separator to the compressor.
[0213] The gas-liquid separator may be provided between the heat
exchanger bypass flow path and the outdoor expansion apparatus.
[0214] The heat pump type speed heating apparatus may further
include an injection refrigerant controller that can be installed
in the injection line to control vaporized refrigerant injected to
the compressor, and may be closed at the time of a starting
operation and opened after stabilization.
[0215] The cooling cycle circuit can further include a
cooling/heating switching valve that switches between a cooling
operation and a heating operation. The hot water supply flow path
may include a hot water supply inflow flow path leading the
refrigerant that has been compressed in the compressor to the hot
water supply heat exchanger and a hot water outflow flow path
leading the refrigerant that has flowed out from the hot water
supply heat exchanger to the cooling/heating switching valve. The
hot water supply inflow flow path and the hot water supply outflow
flow path may be connected to the compressor and the
cooling/heating switching valve respectively. The heat exchanger
bypass flow path may be connected to the hot water supply outflow
flow path.
