Return to compressor 1, complete one and heat circulation.Air first passes through spray-type heat exchanger 501 and dehumidifies, subsequently into evaporation
Device 503 carries out heat exchange, owing to now dew point temperature is less than the temperature of evaporator surface, so will not frosting.Can be by controlling
The aperture of first expansion valve the 4, second expansion valve 502 makes spray-type heat exchanger 501 and finned evaporator 503 be different steamings
Send out temperature.
See Fig. 2, under regeneration mode: a mouth 201 of cross valve turns on No. four mouths 204, No. two mouths 202 and No. three mouths
203 conductings, the first expansion valve 4 fully opens, and the second expansion valve 502 normally throttles, and system enters regeneration mode.Now,
With reduce indoor heat exchanger, the blower fan of indoor heat exchanger 3 or water pump stall can be taken heat energy power, cold-producing medium is pressed through compressor 1
Shorten the gas of High Temperature High Pressure into, enter indoor heat exchanger 3 partial condensation through cross valve 2, subsequently into spray-type heat exchanger 501
Condensation is with supercool further, and after the second expansion valve 502 throttling, in Fin and tube evaporator 503, evaporation endothermic is overheated gas,
Return to compressor 1 by cross valve 2, complete a regeneration cycle.Now, air is at spray-type heat exchanger 501 and fin
It is circulated by air channel between formula vaporizer 503, constantly takes the moisture absorbed under heating mode to finned evaporator 503
Condensation discharge system, after solution returns to original state, regeneration mode terminates.
See Fig. 3, under refrigeration mode: a mouth 201 of cross valve turns on No. two mouths 202, No. three mouths 203 and No. four mouths
204 conductings, the first expansion valve 4 normally throttles, the second expansion valve 502 fully opens, and system enters refrigeration mode.Cold-producing medium
It is compressed into high temperature and high pressure gas through compressor 1, condenses in cross valve 2 enters outdoor heat exchange unit 5, spray simultaneously
Pouring formula heat exchanger 501 is sprayed water, and the condensation temperature of the liquid refrigerant being condensed out due to spray-type heat exchanger 501 is more air-cooled than conventional
The condensation temperature of condenser is low, and can improve the degree of supercooling of cold-producing medium, therefore improves Energy Efficiency Ratio and the refrigerating capacity of system,
The liquid refrigerant condensed from spray-type heat exchanger 501 through the throttling of the first expansion valve 4 laggard enter in indoor heat exchanger 3
Evaporation endothermic, is then passed through cross valve 2 and returns the entrance of compressor 1, completes a kind of refrigeration cycle.
Specific embodiment two
When explanation uses air circulating type system solution below, the present invention is at heating mode, regeneration mode and refrigeration mode
Idiographic flow and operation principle.
See Fig. 4, under heating mode: a mouth 201 of cross valve turns on No. four mouths 204, No. two mouths 202 and No. three mouths
203 conductings, first expansion valve the 4, second expansion valve 502 normally throttles, and first air-valve the 509, second air-valve 510 is opened, and follows
Ring air-valve 511 cuts out, and system enters heating mode.Cold-producing medium is compressed into high temperature and high pressure gas through compressor 1, through four-way
Valve 2 enters indoor heat exchanger 3 and is condensed into the saturated liquid of high pressure, after the once throttling of the first expansion valve 4, and part refrigeration
Agent is evaporation endothermic in spray-type heat exchanger 501, at finned evaporator 503 after the second throttle of the second expansion valve 502
Interior evaporation endothermic completely is overheated gas.Last cold-producing medium returns to compressor 1 by cross valve 2, completes one and heats circulation.
Air first passes through spray-type heat exchanger 501 and dehumidifies, and carries out heat exchange subsequently into vaporizer 503, due to now dew point temperature
Less than the temperature of evaporator surface, so will not frosting.Can be by controlling opening of first expansion valve the 4, second expansion valve 502
It is different evaporating temperatures that degree makes spray-type heat exchanger 501 and finned evaporator 503.
See Fig. 5, under regeneration mode: a mouth 201 of cross valve turns on No. four mouths 204, No. two mouths 202 and No. three mouths
203 conductings, the first expansion valve 4 fully opens, and the second expansion valve 502 normally throttles, first air-valve the 509, second air-valve 510
Closing, circulation air-valve 511 is opened, and system enters regeneration mode.Now, can be by the blower fan of indoor heat exchanger 3 or water pump stall
With reduce indoor heat exchanger take heat energy power, cold-producing medium is compressed into the gas of High Temperature High Pressure through compressor 1, through cross valve 2
Enter indoor heat exchanger 3 partial condensation, condense further subsequently into spray-type heat exchanger 501 and supercool, expand through second
After valve 502 throttling, in finned evaporator 503, evaporation endothermic is overheated gas, returns to compressor 1 by cross valve 2,
Complete a regeneration cycle.Now, air is carried out by air channel between spray-type heat exchanger 501 and finned evaporator 503
Circulation, constantly takes the moisture absorbed under heating mode to finned evaporator 503 and condenses discharge system, treat that solution returns to
After state originally, regeneration mode terminates.
See Fig. 6, under refrigeration mode: a mouth 201 of cross valve turns on No. two mouths 202, No. three mouths 203 and No. four mouths
204 conductings, the first expansion valve 4 normally throttles, the second expansion valve 502 fully opens, first air-valve the 509, second air-valve 510
Opening, circulation air-valve 511 cuts out, and system enters refrigeration mode.Cold-producing medium is compressed into high temperature and high pressure gas through compressor 1,
Condensing in cross valve 2 enters outdoor heat exchange unit 5, spray-type heat exchanger 501 is sprayed water simultaneously, owing to fountain changes
The condensation temperature of the liquid refrigerant that hot device 501 is condensed out is lower than the condensation temperature of conventional air cooled condenser, and can improve
The degree of supercooling of cold-producing medium, therefore improves Energy Efficiency Ratio and the refrigerating capacity of system, the liquid condensed from spray-type heat exchanger 501
State cold-producing medium through the throttling of the first expansion valve 4 laggard enter evaporation endothermic in indoor heat exchanger 3, be then passed through cross valve 2 and return
The entrance of compressor 1, completes a kind of refrigeration cycle.
