Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims priority under 35 U.S.C.
.sctn.119(a) to Korean Patent Application No. 10-2014-0157354,
filed on Nov. 12, 2014, in the Korean Intellectual Property Office,
the disclosure of which is incorporated herein by reference.
BACKGROUND
[0002] 1. Field
[0003] The present disclosure relates generally to an air
conditioning device, and more particularly to an air conditioning
device, which can simultaneously perform ventilation and
cooling/heating.
[0004] 2. Description of the Related Art
[0005] Recently, the moderns make a living indoors, such as inside
a building or a means of transportation, most of the day. In order
to keep the interior of a room in an agreeable environment, a
window may be opened for ventilation, or a separate ventilation
device may be installed. However, this may cause inconvenience.
[0006] In order to solve the above-described problem, various air
conditioning devices having ventilation functions have recently
been proposed. However, an air conditioning device having a
ventilation function separately requires a flow path to perform
cooling and heating and another flow path to perform ventilation.
For this, an air conditioning device in the related art may include
a plurality of indoor air inlet ports for the inflow of indoor air,
or an outdoor air inlet port and an outdoor air discharge port may
be modified to match a case where they perform their own
functions.
[0007] However, if a plurality of indoor air inlet ports are
provided, it becomes necessary to install separate ducts for the
respective indoor air inlet ports, and thus the manufacturing cost
is increased. Further, additional space is required in installing
the air conditioning device, and a plurality of ducts should be
connected to the air conditioning device which causes
inconvenience.
[0008] Further, since air pollution has recently become severer, it
is preferable to provide a filter for filtering pollution materials
from external air on the side of the outdoor air inlet port.
Accordingly, in the case where the outdoor air inlet port and the
outdoor air discharge port are modified to match the case where
they perform their own functions, it is required to install
additional filters for filtering pollution materials from external
air on the outdoor air inlet port and the outdoor air discharge
port, and this causes the manufacturing cost of the product to be
increased.
SUMMARY
[0009] The present disclosure has been made to address at least the
above problems and/or disadvantages and to provide at least the
advantages described below. Accordingly, an aspect of the present
disclosure provides an air conditioning device, which can reduce
the number of filters required and thus can reduce the
manufacturing cost of the air conditioning device by designing a
flow path so that an outdoor air inlet port and an indoor air inlet
port can be constantly maintained even if the performing function
of the air conditioning device is modified.
[0010] Another aspect of the present disclosure provides an air
conditioning device, which can reduce power consumption of a fan by
reducing air resistance that is caused by filters through reduction
of the number of the filters required in the air conditioning
device.
[0011] Still another aspect of the present disclosure provides an
air conditioning device, which can reduce power consumption that is
caused by driving of an exhaust fan by adjusting the position of
the exhaust fan so as to drive the exhaust fan only in case of
need.

flow path, the second flow path, and the fourth flow path, and the
second discharge port may correspond to outlet of the first flow
path, the third flow path, and the fifth flow path.
[0014] The heat recovery ventilator may be arranged in a portion of

correspondingly arranged on the first flow path, the second flow
path, the third flow path, the fourth flow path and the fifth flow
path and configured to selectively open and close the first flow
path, the second flow path, the third flow path, the fourth flow
path and the fifth flow path, respectively.
[0016] The first to fifth flow path opening and closing portions
may be dampers.
[0017] When the cooling and heating and the heat recovery
ventilation are performed together, an amount of airflow that
passes through the first flow path, the second flow path and third
flow paths may be adjusted by a degree of opening of first flow
path, the second flow path and third flow path opening and closing
portions among the first to fifth flow path opening and closing
portion.
[0018] A first filter may be arranged in a part of a common section
between the third flow path and fifth flow path to be adjacent to
the inlet port.

section between the second flow path and fourth flow path to be
adjacent to the discharge port, and the exhaust fan may be driven
while the second flow path or the fourth flow path is open.
[0020] A second filter may be arranged in a part of a common
section between the first flow path, the second flow path, and the

DETAILED DESCRIPTION
[0037] Hereinafter, an air conditioning device 1 according to an
embodiment of the present disclosure will be described with
reference to the accompanying drawings. In describing the
embodiment of the present disclosure, a detailed description of
known constructions or functions will be omitted if it is deemed
that such description would make the gist of the present disclosure
unnecessarily vague. In the drawings, to help the understanding of
the present disclosure, sizes of some constituent elements may be
exaggerated for clarity in explanation.
[0038] FIG. 1 is a perspective view illustrating an air
conditioning device 1 according to an embodiment of the present
disclosure, and FIG. 2 is a perspective view illustrating the shape
of a main body portion 100 from which first to fourth ducts 201 to
204 are separated in the air conditioning device 1 of FIG. 1. FIGS.
3 and 4 are exploded perspective views illustrating the main body
portion 100 of FIG. 2, from which external covers 115 and a second
filter 134 are removed, in a state where internal covers 116 are
separated from the main body 100.
[0039] Referring to FIGS. 1 to 4, an air conditioning device
according to an embodiment of the present disclosure includes a
main body portion 100 and first to fourth ducts 201 to 204.
[0040] The main body portion 100 includes a housing 110, first to
fifth flow path opening/closing portions 121 to 125, an indoor heat
exchanger 131, a heat recovery ventilator 132, first to third
filters 133 to 135, a supply fan 136, and an exhaust fan 137.
[0041] The first to fifth flow path opening/closing portions 121 to
125, the indoor heat exchanger 131, the heat recovery ventilator
132, the first to third filters 133 to 135, the supply fan 136, and
the exhaust fan 137 are provided in the housing 110, and the
housing 110 forms flow paths through which indoor air and outdoor
air flow. Further, the first to fourth ducts 201 to 204 to be
described later are connected and fixed to the housing 110.
[0042] The first to fifth flow path opening/closing portions 121 to
125 selectively open or close first to fifth flow paths 301 to 305
to be described later. The first to fifth flow path opening/closing
portions 121 to 125 may include dampers, but are not limited
thereto. The dampers may also be omitted.
[0043] The indoor heat exchanger 131 is connected to an outdoor
unit (not illustrated) of a freezing cycle, and is provided with a
plurality of refrigerant pipes through which refrigerant flows.
Through such refrigerant pipes, the indoor heat exchanger 131
performs heat exchange with air that passes through the indoor heat
exchanger 131. That is, in the case of performing indoor cooling,
the indoor heat exchanger 131 absorbs heat from the air, whereas in
the case of performing indoor heating, it discharges heat to the
air.
[0044] The heat recovery ventilator 132 includes a plurality of
flow paths through which indoor air and outdoor air, which have a
temperature difference, flow, and a plurality of pipes are arranged
to be alternately directed in different directions so that heat
exchange is performed between the indoor air and the outdoor
air.
[0045] In the case of using the heat recovery ventilator 132,
ventilation is performed and at the same time, heat exchanging is
primarily performed between the indoor air and the outdoor air.
Accordingly, in the case where heat recovery ventilation and
cooling/heating are performed together, the rate of heat exchange
to be performed by the indoor heat exchanger is reduced, and thus
cooling/heating efficiency can be increased.
[0046] The first filter 133 is arranged adjacent to a first inlet
port 111 to be described later in order to perform filtering of
pollution materials included in air that flows in from an outside.
The first filter 133 may include a HEPA (High Efficiency
Particulate Air) filter that can collect fine dust.
[0047] The second filter 134 is arranged adjacent to a second inlet
port 112 to be described later in order to perform filtering of
pollution materials included in air that flows in from the interior
of a room. In particular, the second filter 134 may filter the
pollution materials included in the indoor air when indoor
cooling/heating is performed through making the indoor air directly
pass through the indoor heat exchanger 131.
[0048] The third filter 135 may perform filtering of pollution
materials included in the air that flows to the interior of a room
when the cooling/heating or pure ventilation is performed. The
third filter 135 may include a K-type filter that collects fine
dust using an electric field.
[0049] The supply fan 136 generates an air flow to discharge the
air in the air conditioning device 1 to the interior of a room. A
plurality of supply fans 136 may be provided.
[0050] The exhaust fan 137 generates an air flow to discharge the
air in the air conditioning device 1 to the outside. A plurality of
exhaust fans 137 may be provided.
[0051] Since the first to fifth flow path opening/closing portions
121 to 125, the indoor heat exchanger 131, the heat recovery
ventilator 132, the first to third filters 133 to 135, the supply
fan 136, and the exhaust fan 137 belong to the technology well
known in the art, the detailed explanation thereof will be
omitted.
[0052] In addition, the housing 110 is provided with the first
inlet port 111, the second inlet port 112, a first discharge port
113, and a second discharge port 114, which are formed on outer
surfaces of the housing 110.
[0053] The first inlet port 111 is an inlet which is connected and
fixed to the first duct 201 to be described later to communicate
with the outside and makes the outdoor air flow into the air
conditioning device 1. Accordingly, it is preferable that the first
filter 133 is arranged adjacent to the first inlet port 111.
[0054] The second inlet port 112 is an inlet which is connected and
fixed to the second duct 202 to be described later to communicate
with the interior of a room and makes the indoor air flow into the
air conditioning device 1. Specifically, the first flow path
opening/closing portion 121 and the fourth flow path
opening/closing portion 124 are arranged in the second inlet port
112, and a first ventilation port 141 is formed therein. Further,
it is preferable that the second filter 134 is arranged adjacent to
the second inlet port 112.
[0055] The first discharge port 113 is an outlet which is connected
and fixed to the third duct 203 to be described later to
communicate with the outside and discharges the air in the air
conditioning device 1 to the outside. Accordingly, it is preferable
that the exhaust fan 137 is arranged adjacent to the first
discharge port 113.
[0056] The second discharge port 114 is an outlet which is
connected and fixed to the fourth duct 204 to be described later to
communicate with the interior of a room and discharges the air in
the air conditioning device 1 to the interior of a room.
Accordingly, it is preferable that the supply fan 136 is arranged
adjacent to the second discharge port 114.
[0057] Further, the housing 110 includes an external cover 115 and
an internal cover 116.
[0058] The external cover 115 forms an external appearance of the
housing 110 and helps forming of flow paths to be described later.
Further, the internal cover 116 does not form the external
appearance, but helps forming of the flow paths inside the housing
110.
[0059] Then, the first duct 201 is connected and fixed to the first
inlet port 111, and extends toward the outside so that the outdoor
air flows in through the first duct 201.
[0060] The second duct 202 is connected and fixed to the second
inlet port 112, and extends toward the interior of a room so that
the indoor air flows in through the second duct 202.
[0061] The third duct 203 is connected and fixed to the first
discharge port 113, and extends toward the outside so that the air
in the air conditioning device 1 is discharged to the outside.
[0062] The fourth duct 204 is connected and fixed to the second
discharge port 114, and extends toward the interior of a room so
that the air in the air conditioning device 1 is discharged to the
interior of a room.
[0063] The first to fifth flow paths 301 to 305, through which the
indoor air or the outdoor air flows, are formed in the main body
100 of the air conditioning device 1. The first to fifth flow paths
301 to 305 will be described in detail in relation to the operation
of the air conditioning device 1 according to an embodiment of the
present disclosure.
[0064] Hereinafter, the cooling/heating, heat recovery ventilation,
and pure ventilation processes of the air conditioning device 1 as
constructed above according to an embodiment of the present
disclosure will be described.
[0065] FIG. 5 is a schematic diagram illustrating flow paths in the
case where the air conditioning device 1 according to an embodiment
of the present disclosure performs cooling/heating through the
indoor heat exchanger 131, and FIG. 6 is a schematic diagram
illustrating flow paths in the case where the air conditioning
device 1 performs heat recovery ventilation through the heat
recovery ventilator 132. FIG. 7 is a schematic diagram illustrating
flow paths in the case where the air conditioning device 1 performs
pure ventilation, and FIG. 8 is a schematic diagram illustrating
flow paths in the case where the air conditioning device 1 performs
both the cooling/heating and heat recovery ventilation. Members
that are darkly indicated are driving members, and members that are
not darkly indicated are non-driving members.
[0066] Referring to FIGS. 3 to 5, in the case where the air
conditioning device 1 according to an embodiment of the present
disclosure performs the cooling/heating, the first flow path
opening/closing portion 121 is opened, and air flows through the
first flow path 301 that is indicated by a thick line.
Specifically, in the case of performing the cooling/heating,
outdoor air does not flow to the interior of a room, but the
cooling/heating is performed through circulation of the indoor air
only. That is, power consumption of the indoor heat exchanger 131
is increased, but indoor cooling/heating can be performed
quickly.
[0067] First, the indoor air flows into the air conditioning device
1 through the second inlet port 112. The inflow air passes through
the second filter 134 that filters pollution materials. Then, the
indoor air flows only toward the first flow path opening/closing
portion 121 that is in an open state among the first flow path
opening/closing portion 121, the second flow path opening/closing
portion 122, and the fourth flow path opening/closing portion
124.
[0068] The air that has passed through the first flow path
opening/closing portion 121 passes through the second filter 134
for filtering the pollution materials once more, and then passes
through the indoor heat exchanger 131 that performs heat exchange.
As described above, in order for the air conditioning device 1 to
perform cooling, the air discharges heat to the indoor heat
exchanger 131, whereas in order to perform heating, the air absorbs
heat from the indoor heat exchanger 131.
[0069] The heat-exchanged air is directed to the second discharge
port 114 through the supply fan 136. The air that is discharged
from the second discharge port 114 returns to the interior of a
room through the fourth duct 204.
[0070] In this case, since the exhaust fan 137 is not positioned on
the first flow path 301, it is not driven when the cooling/heating
is performed. Accordingly, unnecessary power consumption can be
reduced.
[0071] Next, referring to FIGS. 3, 4, and 6, in the case where the
air conditioning device 1 according to an embodiment of the present
disclosure performs the heat recovery ventilation, the second flow
path opening/closing portion 122 and the third flow path
opening/closing portion 123 are opened, and the air flows through
the second flow path 302 that is indicated by a dotted line and the
third flow path 303 that is indicated by a thick line.
Specifically, in the case where the heat recovery ventilation is
performed, the outdoor air flows to the interior of a room, and the
indoor air is discharged to the outside.
[0072] First, the indoor air flows into the air conditioning device
1 through the second inlet port 112. The inflow air passes through
the second filter 134 that filters pollution materials. Then, the
indoor air flows only toward the second flow path opening/closing
portion 122 that is in an open state among the first flow path
opening/closing portion 121, the second flow path opening/closing
portion 122, and the fourth flow path opening/closing portion
124.
[0073] Accordingly, the indoor air flows toward the heat recovery
ventilator 132 after passing through the first ventilation port 141
that is directed to the second flow path opening/closing portion
122. Then, the indoor air flows through a first surface 132a of the
heat recovery ventilator 132 and is discharged through a second
surface 132b of the heat recovery ventilator 132. In this case, the
indoor air exchanges heat with the outdoor air that flows through
the third flow path 303.
[0074] Specifically, in the case of cooling the interior of a room,
the temperature of the indoor air is lower than the temperature of
the outdoor air, and thus heat is transferred from the outdoor air
to the indoor air. In contrast, in the case of heating the interior
of a room, the temperature of the indoor air is higher than the
temperature of the outdoor air, and thus heat is transferred from
the indoor air to the outdoor air.
[0075] Thereafter, the air that is discharged through the second
surface 132b moves to an upper side on which the exhaust fan 137 is
arranged through the second flow path opening/closing portion 122.
In this case, the air moves through a space between the right
external cover 115 and the internal cover 116.
[0076] Thereafter, the air that has reached the exhaust fan 137 is
discharged through the first discharge portion 113 after passing
through the exhaust fan 137, and then is discharged to the outside
through the third duct 203.
[0077] Next, the outdoor air flows into the air conditioning device
1 through the first inlet port 111. The inflow outdoor air passes
through the first filter 133 that filters the pollution materials.
Thereafter, the outdoor air flows only toward the third flow path
opening/closing portion 123 that is in an open state between the
third flow path opening/closing portion 123 and the fifth flow path
opening/closing portion 125. The air that has passed through the
third flow path opening/closing portion 123 flows through a third
surface 132c of the heat recovery ventilator 132 and is discharged
through a fourth surface 132d. In this case, the indoor air
exchanges heat with the indoor air that flows through the second
flow path 302.
[0078] Thereafter, the air discharged through the fourth surface
132d moves toward the supply fan 136 through the second ventilation
port 142. Then, the air that has passed through the supply fan 136
is discharged to the interior of a room through the second
discharge port 114.
[0079] In this case, since the indoor heat exchanger 131 is not
operated, but only the heat recovery ventilator 132 is operated,
the indoor temperature is maintained almost as it is. That is, if
the indoor temperature is lower than the outdoor temperature, the
air that has flowed from the outside to the interior of a room
flows to the interior of a room after transferring heat to the air
that is discharged from the interior of a room to the outside, and
thus it becomes cool air having a temperature that is similar to
the indoor temperature. In contrast, if the indoor temperature is
higher than the outdoor temperature, the air that flows from the
outside to the interior of a room flows to the interior of a room
after absorbing heat from the air that is discharged from the
interior of a room to the outside, and thus it becomes warm air
having a temperature that is similar to the indoor temperature.
Accordingly, a user may use the heat recovery ventilation to
perform ventilation with the indoor air maintained in spring or
fall season.
[0080] Next, referring to FIGS. 3, 4, and 7, in the case where the
air conditioning device 1 according to an embodiment of the present
disclosure performs the pure ventilation, the fourth flow path
opening/closing portion 124 and the fifth flow path opening/closing
portion 125 are opened, and the air flows through the fourth flow
path 304 that is indicated by a dotted line and the fifth flow path
305 that is indicated by a thick line. Specifically, in the case
where the pure ventilation is performed, the outdoor air flows to
the interior of a room, and the indoor air is discharged to the
outside.
[0081] First, the indoor air flows into the air conditioning device
1 through the second inlet port 112. The inflow indoor air passes
through the second filter 134 that filters pollution materials.
Then, the indoor air flows only toward the fourth flow path
opening/closing portion 124 that is in an open state among the
first flow path opening/closing portion 121, the second flow path
opening/closing portion 122, and the fourth flow path
opening/closing portion 124.
[0082] The air that has passed through the fourth flow path
opening/closing portion 124 flows toward the exhaust fan 137. The
air that has passed through the exhaust fan 137 is discharged to
the outside through the first discharge port 113.
[0083] Next, the outdoor air flows into the air conditioning device
1 through the first inlet port 111. The inflow outdoor air passes
through the first filter 133 that filters the pollution materials.
Thereafter, the outdoor air flows only toward the fifth flow path
opening/closing portion 125 that is in an open state between the
third flow path opening/closing portion 123 and the fifth flow path
opening/closing portion 125.
[0084] The air that has passed through the fifth flow path
opening/closing portion 125 moves toward the supply fan 136 after
passing through the indoor heat exchanger 131. In this case, since
the indoor heat exchanger 131 is not operated, heat exchange is not
performed even if the outdoor air passes through the indoor heat
exchanger 131.
[0085] Thereafter, the air that has passed through the supply fan
136 is discharged to the interior of a room through the second
discharge port 114.
[0086] In the case of performing the pure ventilation, unlike the
heat recovery ventilation, the air does not pass through the heat
recovery ventilator 132, and thus heat exchange is not performed
between the indoor air and the outdoor air. Accordingly, since the
temperature of the indoor air can be set to be similar to the
temperature of the outdoor air and the ventilation can be
simultaneously performed, it becomes possible to maintain an
agreeable indoor environment. That is, if the temperature of the
indoor air is higher than the temperature of the outdoor air, the
interior of a room can be made cool simultaneously with the
ventilation, while if the temperature of the indoor air is lower
than the temperature of the outdoor air, the interior of a room can
be made warm simultaneously with the ventilation.
[0087] Further, since the inlet and outlet ports of the second flow
path 302 and the third flow path 303 in the case of performing the
heat recovery ventilation are equal to the inlet and outlet ports
of the fourth flow path 304 and the fifth flow path 305 in the case
of performing the pure ventilation, it is sufficient to arrange
only one first filter 133 that filters the pollution materials from
the outdoor air in a place that is adjacent to the first inlet port
111, and thus the number of filters required can be reduced to save
the manufacturing cost of the product. Further, since the number of
filters is reduced, air resistance due to the filters can be
reduced, and thus the power consumption of the supply fan 136 and
the exhaust fan 137 can be reduced.
[0088] Then, referring to FIGS. 3, 4, and 8, in the case where the
air conditioning device 1 according to an embodiment of the present
disclosure simultaneously performs the cooling/heating and the heat
recovery ventilation, the first to third flow path opening/closing
portions 121 to 123 are opened among the first to fifth flow path
opening/closing portions 121 to 125, and thus the air flows through
the first to third flow paths 301 to 303.
[0089] In the case of simultaneously performing the cooling/heating
and the heat recovery ventilation, as described above, the heat
recovery ventilator 132 primarily performs heat exchange, and then
the indoor heat exchanger 131 secondarily performs heat exchange.
Accordingly, the rate of heat exchange to be loaded by the indoor
heat exchanger 131 is reduced, and thus cooling/heating efficiency
is increased.
[0090] Specifically, in the case where the cooling/heating and the
heat recovery ventilation are simultaneously performed, the first
flow path opening/closing portion 121 and the second flow path
opening/closing portion 122 are opened among the first flow path
opening/closing portion 121, the second flow path opening/closing
portion 122, and the fourth flow path opening/closing portion 124,
and thus the indoor air flows through the first flow path 301 and
the second flow path 302. Further, the third flow path
opening/closing portion 123 is opened between the third flow path
opening/closing portion 123 and the fifth flow path opening/closing
portion 125, and thus the outdoor air flows through the third flow
path 303.
[0091] In this case, the amount of the indoor air, which flows in
through the second inlet port 112 and flows through the first flow
path 301 and the second flow path 302, is adjusted by the degree of
opening of the first flow path opening/closing portion 121 and the
second flow path opening/closing portion 122. Further, the degree
of opening of the third flow path opening/closing portion 123 is
adjusted to match the amount of air that flows through the first
flow path 30, and thus an inflow amount of the outdoor air can be
adjusted.
[0092] That is, the indoor air that flows in through the second
inlet port 112 flows through a flow path 306 that is indicated by a
dash dot dot line, and then a part of the indoor air flows along
the first flow path 301 that is indicated by a dash dot line and
the remaining part thereof flows along the second flow path 302
that is indicated by a long dotted line. Here, in the same manner
as the air that flows along the second flow path 302 in the case
where the heat recovery ventilation is performed, the air that
flows along the second flow path 302 exchanges heat with the
outdoor air that flows from the heat recovery ventilator 132 to the
third flow path 303, and then is discharged to the outside through
the first discharge port 113.
[0093] Further, the outdoor air, of which the amount is smaller
than the amount of air that flows through the third flow path 303
during the heat recovery ventilation by the third flow path
opening/closing portion 123, flows in through the first inlet port
111. Then, in the same manner as a case where the heat recovery
ventilation is performed, the outdoor air exchanges heat with the
indoor air that flows from the heat recovery ventilator 132 to the
second flow path 302, and then joins the air that flows along the
first flow path 301. In this case, since the inflow outdoor air has
already been heat-exchanged primarily, the rate of secondary heat
exchange, which is to be performed by the outdoor heat exchanger
that is arranged on a flow path 307 through which the joined air
flows, is reduced. In this case, the primary and secondary heat
exchanging processes are the same as heat transfer processes when
the heat recovery ventilation and the cooling/heating are
performed. After the secondary heat exchanging is completed, the
air is discharged to the interior of a room through the second
discharge port 114.
[0094] While the disclosure has been shown and described with
reference to certain embodiments thereof, it will be understood by
those skilled in the art that various changes in form and detail
may be made therein without departing from the spirit and scope of
the present disclosure, as defined by the appended claims.
