Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to generators and more
particularly, to a heat generating system for charge liquid in a
liquid delivering system into heat by means of heat exchange
between the liquid delivering system with the head heat in an
air-conditioning refrigerating system.
[0003] 2. Description of the Related Art
[0004] The operation of an air-conditioning refrigerating system is
to make heat exchange, i.e., to provide a heat transfer effect by
means of cycling a refrigerant to dissipate heat and absorb heat.
On the path of the refrigerant, the refrigerant is returned to the
compressor for compression and output after passed through the cold
room. When condensed (heat dissipated), the temperature of the
high-pressure refrigerant is dropped. Thereafter, the refrigerant
is processed through evaporation to absorb heat. This operation
cycle, i.e., refrigeration cycle is recycled again and again,
providing the desired cooling effect. In this refrigeration cycle,
the refrigerant is in the liquid state during condensation; however
it is turned into the gas state during evaporation.
[0005] Therefore, a regular air-conditioning refrigerating system
is comprised of four main parts, namely, the compressor, the
condenser, the refrigerant metering device such as capillary tube,
and the evaporator.
[0006] The compressor uses a motor to compress a low-pressure
low-temperature gaseous refrigerant into a high-pressure
high-temperature, for example, 275 psig, 90.degree. C. gaseous
refrigerant, such as R-22 that is discharged through the discharge
end of the compressor. Therefore, the compressor is the power
source for the cycling of the air-conditioning refrigerating
system.
[0007] The condenser is adapted to condense the high-pressure
high-temperature gaseous refrigerant into a high-pressure
medium-temperature, for example, 269 psig, 46.degree. C. liquefied
refrigerant by means of the medium of air or water. When the
refrigerant is passing through the evaporator, the evaporator uses
cooling media and/or fan to charge heat to the refrigerant.
[0008] The spoiler can be a capillary tube or expansion valve
adapted to turn the high-pressure medium-temperature liquefied
refrigerant into a low-pressure low-temperature liquefied
refrigerant for quick evaporation in the evaporator.
[0009] The evaporator is to evaporate the low-pressure liquefied
refrigerant into a low-pressure low-temperature, for example, 65
psig, 3.degree. C. gaseous refrigerant. When air flowing through
the evaporator, the refrigerant absorbs heat energy from the air,
and therefore the refrigerant is turned into vapor. When passing
from the evaporator to the intake end of the compressor, the
temperature of the refrigerant is raised to about 11.degree. C.
[0010] Actually, when the refrigerant of the air-conditioning
refrigerating system passes through the evaporator, the refrigerant
absorbs heat. But the lubricating oil in the piping to be turned
into a paste-like status that does not facilitate lubrication of
the compressor, and increasing of the consumption of electric
current and the load of the compressor. In consequence, the
performance of the compressor is lowered down.
[0011] In the circulation path of the refrigerant of the aforesaid
air-conditioning refrigerating system, the pipe segment in
proximity to the discharge end of the compressor to discharge the
high-pressure high-temperature refrigerant with lubricating oil is
called the head heat segment. The temperature of this head heat
segment is about 90.degree. C. that cannot charge a liquid, for
example, water into hot water or even steam. Therefore, when the
refrigerant passes through the condenser, the temperature of the
refrigerant is lowered to about 46.degree. C. This heat transfer
loss is against the policy of energy saving and carbon reduction.
Therefore, it is common problem how to effectively utilize the heat
energy of the head heat at the discharge end of the compressor of
an air-conditioning refrigerating system, for example, to utilize
this heat energy for making heat exchange to charge liquid into hot
water or even steam.

BRIEF DESCRIPTION OF THE DRAWINGS
[0017] FIG. 1 is a perspective view of a heat generating system in
accordance with the present invention.
[0018] FIG. 2 is a layout of the heat generating system in
accordance with the present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0019] Referring to FIGS. 1 and 2, a heat generating system in
accordance with the present invention is shown comprised of an
air-conditioning refrigerating system 1 and a liquid delivering
system 2.
[0020] The air-conditioning refrigerating system 1 comprises a
compressor 11, a discharge line 12, a condenser 13, a condenser
main pipe 14, a liquid distributor 15, a spoiler 16, an evaporator
17 and a suction line 18.
[0021] The compressor 11 is of the known art, using the power of a
mover, for example, motor, to recycle a low pressure low
temperature gaseous refrigerant, for example, R-22, from the
suction line 18 and to compress it into a high pressure and high
temperature status, for example, 500 psig 160.degree. C. enabling
the high-pressure and high-temperature gaseous refrigerant to be
discharged with lubricating oil out of the discharge end of the
compressor 11 into the discharge line 12.
[0022] The discharge line 12 has its one end, namely, the intake
end connected to the discharge end of the compressor 11, and its
other end, namely, the output end connected to the condenser 13.
The intake end of the discharge line 12 has a head heat segment 121
connected to the discharge end of the compressor 11. Therefore, the
temperature of this head heat segment 121 can reach 160.degree. C.,
sufficient to charge liquid, for example, water into hot water or
even steam. The water circulation system 2 comprises a delivery
pipe 21 that has a contact segment 211 kept in contact with the
head heat segment 121 of the discharge line 12 at the
air-conditioning refrigerating system 1 for heat exchange to have
the liquid flowing through the contact segment 211 be heated into
steam. In order to increase the contact area between the head heat
segment 121 and the contact segment 211, the head heat segment 121
and the contact segment 211 are wrapped together. Preferably, the
contact segment 211 is sleeved onto the head heat segment 121. The
contact area between the head heat segment 121 and the contact
segment 211 are wrapped with an insulation material, for example,
insulation polymer compound. Heat exchange between the head heat
segment 121 and the contact segment 211 effectively initially
lowers the temperature of the high-pressure and high-temperature
gaseous refrigerant with oil being discharged out off the
compressor 11 then to the condenser 13.
[0023] The condenser 13 condensates the gaseous refrigerant into a
liquid state by means of using a cooling medium, such as air or
water, to dissipate heat. The condenser 13 is connected to the
output end of the discharge line 12, comprising a plurality of
condenser coils 131 connected to the output end of discharge line
12 for cooling and storing the high-pressure refrigerant with oil,
a plurality of radiation fins 132 surrounding the condenser coils
131 for dissipating heat from the condenser coils 131, and a fan
133 for causing currents of air to carry heat away from the
radiation fins 132. By means of the condenser coils 131, the
radiation fins 132 and the fan 133, the condenser 13 condenses the
high-pressure high-temperature gaseous refrigerant into a
high-pressure moderate-temperature state, for example, about 494
psig 46.degree. C.
[0024] The condenser main pipe 14 gathers the condenser coils 131
into one single pipe. Therefore, the refrigerant and the oil are
gathered together to flow through the condenser main pipe 14 after
condensed through the condenser coils 131. At this time, the liquid
refrigerant that is flowing through the condenser main pipe 14
still carries a certain amount of thermal energy.
[0025] The liquid distributor 15 is connected to at least one tube
off the condenser main pipe 14, and extending alternatively
circulate through bottom of the evaporator 17 to lower the
temperature of the liquid refrigerant with oil and to deliver the
cooled liquid refrigerant with oil to the spoiler 16.
[0026] Actually, the liquid distributor 15 is a tube provided with
a series of bends in alternate directions and constructed according
to U.S. Pat. No. 6,370,901, entitled "Compound evaporation system
and device thereof" that is issued to the present inventor. The
liquid distributor 15 is installed in the bottom side of the
evaporator 17. By means of the evaporation effect of the evaporator
17, the temperature and pressure of the refrigerant and the oil
flowing through the liquid distributor 15 are lowered to, for
example, about 25.degree. C. 300 psig. The liquid distributor 15
can be a single coil tube formed of a number of capillary tubes for
guiding in the liquid refrigerant, the oil and bubbles from the
condenser 13. When the liquid refrigerant and the oil enter the
capillary tubes of the liquid distributor 15, the fine diameters of
the capillary tubes of the liquid distributor 15 stop bubbles
outside the inlet, enhancing condensing efficiency is like the
effect of the method for reinforcing condensation and device
thereof of Taiwan Patent No. 494222 that is issued to the present
inventor.
[0027] The spoiler 16 can be formed of an expansion valve or
capillary tube, and is adapted to force the liquid refrigerant
passing there through into a mist, lowering the pressure of the
liquid refrigerant to, for example, about 50 psi for evaporation by
the evaporator 17.
[0028] The evaporator 17 comprises a plurality of evaporator coils
171 connected to the output end of the spoiler 16 for inject the
mist-like refrigerant for quick evaporation, a plurality of
radiation fins 172 arranged around the evaporator coils 171 for
thermal dissipation from the evaporator coils 171 to enhance
evaporation, and a fan 173 for causing currents of air to carry
heat from the radiation fins 172 to have the mist-like refrigerant
be evaporated into vapor. For example, 50 psig -3.degree. C.
refrigerant is flowing through the evaporator coils 171, it absorbs
heat energy and is caused to evaporate. The latent heat function of
the evaporator 17 causes the refrigerant to be charge from a liquid
state into a gas state so that the temperature of the refrigerant
is raised from -3.degree. C. to 10.degree. C. approximately after
absorb heat.
[0029] As stated above, the bottom of the evaporator 17 is kept in
contact with the liquid distributor 15. As illustrated, the
evaporator 17 has a plurality of through holes 174 in the bottom
side for the insertion of the liquid distributor 15 in a detoured
manner for heat exchange, i.e., condensed water drops from the
evaporator coils 171 and radiation fins 172 of the evaporator 17
during evaporation to flow over the liquid distributor 15 and to
exchange heat from the liquid distributor 15.
[0030] The suction line 18 is a tubular member having its one end
connected to the evaporator coils 171, which are arranged in one
tube and the other end connected to the intake end of the
compressor 11. Therefore, the gaseous refrigerant backs to the
compressor to complete a cycle. Before returning to the compressor
11, the gaseous refrigerant with oil absorbs heat energy from the
discharge head. In order to raise temperature from low pressure and
low temperature condition, for example, intake 50 psig 10.degree.
C. to about 160.degree. C. discharge, the suction line 18 and the
discharge line 12 have a respective heat conducting segment 181 or
122 attached together for heat exchange. By means of this heat
exchange action, the gaseous refrigerants with oil are pre-heated
to about 25.degree. C. before returning to the compressor 11. When
pre-heat the lo side refrigerant with oil softened the oil,
facilitating running of the compressor 11. Rise in the expiratory
volume causes the winding in the compressor to release heat,
thereby raising the temperature of the discharge head and higher
the compression ratio, lowering the consumption of electric
current.
[0031] The liquid delivering system 2 has the contact segment 211
of its delivery pipe 21 coupled to the head heat segment 121 for
heat exchange. The liquid passing through the delivery pipe 21 is
heated into hot water or steam according to the different thickness
of inside diameter of the delivery pipe 21. The produced hot water
can be used for washing or bathing. The produced steam has a
temperature about 140.degree. C. and is flowing through the
delivery pipe 21 into a steam receiver 22 for storage. The steam
receiver 22 can be connected to a water reservoir 23 through a
connection pipe 221 for enabling the steam, which has a temperature
about 134.degree. C. when flowed out of the steam receiver 22, to
heat liquid in the water reservoir 23. The water reservoir 23 is
connected with the delivery pipe 21 and a water inlet pipe 231,
forming a steam-liquid circulation system. Because the water
contained in the water reservoir 23 is heated by the steam from
steam receiver 22, it can be quickly changed into steam when
passing through the contact segment 211 of the delivery pipe 21 to
make heat exchange with the head heat segment 121 of the discharge
line 12.
[0032] Further, the steam receiver 22 has a relief pipe 221 which
can be connected thereto for discharge of the steam for other
purposes, for example, for the preparation of distilled water, for
heating a water tank, or for the purpose of washing or bathing. Or
on the lower section of the water reservoir 23 has an outlet pipe
232 connected thereto for outputting the hot water producing in the
water reservoir 23 for the purpose of washing or bathing.
[0033] By means of transferring heat energy from the head heat
segment 121 of the discharge line 12 of the compressor 11 in the
air-conditioning refrigerating system 1 to the contact segment 211
of the delivery pipe 21 of the liquid delivering system 2, liquid
flowing through the delivery pipe 21 of the liquid delivering
system 2 is quickly turned into hot water or steam. This heat
energy is over twice of the total of the latent heat and sensible
heat of the condenser 13. Further, the pressure ratio between the
high pressure and the low pressure according to the present
invention can be as high as 8:1 (500 psig:45 psig) making an
outstanding difference when compared to conventional
air-conditioning refrigerating systems or heat pumps.
[0034] Therefore, the application of the invention has the
advantage of effectively utilizing the heat energy of the head heat
of the discharge end of the compressor in an air-conditioning
refrigerating system to make heat exchange with a liquid delivering
system for changing a liquid flowing through the piping of the
liquid delivering system into hot water or steam for other
purposes. This arrangement avoids waste of heat energy and reduces
discharge of waste heat, Further, the invention enables the
temperature of the gaseous refrigerant and oil to be raised before
return back to the compressor, thereby softening the oil,
facilitating smooth running of the compressor and having the
compressor be thoroughly lubricated. In consequence, the invention
increases the compression ratio of the compressor and enables the
heat energy of the winding of the compressor to be released,
lowering electric current consumption and exhibiting the effects of
energy saving.
[0035] Although a particular embodiment of the invention has been
described in detail for purposes of illustration, various
modifications and enhancements may be made without departing from
the spirit and scope of the invention. Accordingly, the invention
is not to be limited except as by the appended claims.
