One end of a four-way reversing valve is connected with a double-pipe heat exchanger; the double-pipe heat exchanger is connected with a liquid reservoir, the liquid reservoir is connected with a dry filter; the dry filter is connected with a thermostatic expansion valve; the thermostatic expansion valve is connected with a one-way valve; the one-way valve is connected with a parallel fin type heat exchanger and an electromagnetic valve; the fin type heat exchanger is connected with the other end of the four-way reversing valve; the other two ports of the four-way reversing valve are respectively connected with a compressor and a gas-liquid separator; the electromagnetic valve, a capillary and a heat accumulator are in series connection and then are connected to the inlet of the gas-liquid separator; and the gas-liquid separator is connected with the compressor to form a loop. The technical effect of the invention is as follows: the problem of the sudden drop of a hot water temperature caused by the reverse defrosting of a four-way valve of the air-source heat pump water heater unit in winter can be solved.
Description
Technical field
The present invention relates to a kind of air-source heat pump hot water group, relate in particular to a kind of accumulation of heat defrosting air-source heat pump hot water group.
Background technology
The air-source heat pump hot water group is moved under the low temperature environment in the winter time, the easily frosting of finned heat exchanger surface, and frost layer causes the unit heating capacity to descend, and unit must defrost.And the traditional cross valve commutation defrosting mode of the general employing of existing air-source heat pump hot water group, unit is in the process of defrosting, and the heats in a large amount of absorption of the cold-producing medium meeting hot water cause the hot water temperature sharply to descend.
Summary of the invention
The object of the present invention is to provide a kind of accumulation of heat defrosting air-source heat pump hot water group, by the parts such as capillary, magnetic valve, storage heater are set, realized that unit heats and defrosting function in system.Solved the rapid problem that descends of hot water temperature that winter air source heat pump hot water group cross valve commutation defrosting brings.
The present invention is achieved like this, it comprises compressor, four-way change-over valve, gas-liquid separator, double-tube heat exchanger, reservoir, device for drying and filtering, magnetic valve, heating power expansion valve, capillary, storage heater, blower fan, finned heat exchanger, an end joint sleeve heat exchanger that it is characterized in that four-way change-over valve, double-tube heat exchanger connects reservoir, reservoir connects device for drying and filtering, device for drying and filtering connects heating power expansion valve, heating power expansion valve connects check valve, check valve connects finned heat exchanger and magnetic valve in parallel, finned heat exchanger connects the other end of four-way change-over valve, two other port of four-way change-over valve connects respectively compressor and gas-liquid separator, magnetic valve, capillary, be connected to the gas-liquid separator import after the storage heater series connection, gas-liquid separator connects compressor and forms the loop, the other blower fan that is provided with of described finned heat exchanger.
Technique effect of the present invention is: solved the rapid problem that descends of hot water temperature that winter air source heat pump hot water group cross valve commutation defrosting brings.
Description of drawings
Fig. 1 is structural representation of the present invention.
In the drawings, 1, magnetic valve; 2, capillary; 3, storage heater; 4, compressor; 5, four-way change-over valve; 6, gas-liquid separator; 7, double-tube heat exchanger; 8, reservoir; 9, device for drying and filtering; 10, heating power expansion valve; 11, check valve; 12, finned heat exchanger; 13, blower fan.
The specific embodiment
As shown in Figure 1, the present invention is achieved like this, one end joint sleeve heat exchanger 7 of four-way change-over valve 5, double-tube heat exchanger 7 connects reservoir 8, reservoir 8 connects device for drying and filtering 9, device for drying and filtering 9 connects heating power expansion valve 10, heating power expansion valve 10 connects check valve 11, check valve 11 connects finned heat exchanger 12 and magnetic valve 1 in parallel, finned heat exchanger 11 connects the other end of four-way change-over valve 5, two other port of four-way change-over valve 5 connects respectively compressor 4 and gas-liquid separator 6, magnetic valve 1, capillary 2, be connected to gas-liquid separator 6 imports after storage heater 3 series connection, gas-liquid separator 6 connects compressor 4 and forms the loop, and finned heat exchanger 11 next doors are provided with blower fan 13.
1) during heating operation, cross valve is in and heats the position, and blower fan is opened, closed electromagnetic valve.The heat of compressor surface stores in storage heater, and cold-producing medium is compressed into high temperature and high pressure gas in compressor, enters double-tube heat exchanger through four-way change-over valve, finishes exchange heat with water in double-tube heat exchanger, hot water preparing; Then pass through reservoir, device for drying and filtering, behind the heating power expansion valve reducing pressure by regulating flow, absorb the heat of vaporization in the outside air in finned heat exchanger, cold-producing medium becomes low-temp low-pressure gas, returns compressor through gas-liquid separator, four-way change-over valve.
When 2) defrosting moved, the cross valve commutation was the refrigeration position, and blower fan cuts out, the magnetic valve unlatching.Cold-producing medium is compressed into high temperature and high pressure gas in compressor, enter finned heat exchanger through four-way change-over valve, release heat is melted the frost layer on the finned heat exchanger, gas-liquid mixed refrigerant is through magnetic valve, again after the capillary-compensated step-down, enter in the storage heater, absorb the heat in the storage heater and evaporate, return compressor through gas-liquid separator.
