Description
Technical field
The present invention is specifically related to a kind of heat pump operating mode system, particularly a kind of have winter and summer two kinds of operating modes heat pump operating mode system.
Background technology
Existing heat pump is a kind of heating technique that air-conditioning develops and comes, and absorbs heat under a certain temperature, and dispels the heat under higher temperature.Thermal source difference according to heat pump can be divided into air source heat pump, water resource heat pump, earth source heat pump.And the pumped (conveying) medium of heating and refrigeration empty G﹠W commonly used.
Air source heat pump is long service time, and system is simple, and is easy to install and use, energy-saving and environmental protection, safety.Use more extensive.Existing air source heat pump system as shown in fig. 1, successively four-way change-over valve 20, heat exchanger 30, check valve 40, expansion valve 50, condenser 60, fluid reservoir 70, compressor 80 are joined together to form a loop by tube connector, heat exchanger 30 is directly to the expansion valve throttling after dried heat exchanger and the hydrothermal exchange.Refrigerant temperature in the heat exchanger is along with the heating of water tank temperature raises, and refrigerant temperature is also raising simultaneously, and when the water tank water temperature was lower than below 40 °, heat pump was in nominal situation.When the water tank water temperature is higher than more than 40 °, just and the standard condition of about 35 ° in air-conditioning be not inconsistent, heat pump just can not normal operation, caused the minimizing of expansion valve amount of restriction, just the many liquid of gas are few, and the coolant quantity that returns compressor also reduces simultaneously, cause the deficiency of compressor air suction amount, the compressor zero load, load strengthens, and has caused the imbalance of higher-pressure region operating mode.The protection of compressor has caused the loss of electric energy.Because the hypertonia between heat exchanger 30 and the expansion valve 50, compressor was not with regard to overload protection when water temperature did not also reach 65 °.To winter, because external temperature is lower than and subzeroly is, the delivery temperature of compressor also descends and contrast during 35 ° of summer high temperatures simultaneously, and the delivery temperature of compressor has only about 45-85 °, and at this moment water tank temperature can added again.
Summary of the invention
The invention provides a kind of heat pump operating mode system, purpose is to solve the prior art problem, provide a kind of have summer and winter two kinds of operating modes, and the efficient of heat pump can be improved in the winter time the time, the heat pump operating mode system that perfect compressor is changed from the HTHP to the low-temp low-pressure.
The present invention's technical scheme that adopts of dealing with problems is:
Heat pump operating mode system, successively heat exchanger 1, second check valve 2, electromagnetic steering valve 3, cooler 13, the 4th check valve 4, expansion valve 5, dehumidifier 6, fluid reservoir 7, compressor 8, the 9th check valve 9, solenoid directional control valve 10 are joined together to form first loop by tube connector, electromagnetic steering valve 3, cooler 13, the 4th check valve 4, the 11 check valve 11, winter, heater 12 was joined together to form second loop, and wherein winter, heater 12 was connected with fluid reservoir 7 one ends; Solenoid directional control valve 10, heat exchanger 1 and second check valve 2 form the 3rd loop.
Beneficial effect of the present invention: between the heat exchanger of mesohigh and expansion valve, increasing a cooler in this heat pump; can be cooled to the mesolow throttling to the high pressure refrigerant in the heat exchanger by cooler; solved in the prior art owing to there is not the cooling of cooler; the heat exchanger internal pressure is too high; the problem of compressor high voltage protective, the perfect conversion of compressor from the HTHP to the low-temp low-pressure.And in the native system winter heater in the winter time the time the waste heat in the heat exchanger by the heating of heater supply compressor, improved the delivery temperature of compressor in winter, strengthened the efficient of heat pump.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further details.
Heat pump operating mode system as shown in Figure 2, successively heat exchanger 1, second check valve 2, electromagnetic steering valve 3, cooler 13, the 4th check valve 4, expansion valve 5, dehumidifier 6, fluid reservoir 7, compressor 8, the 9th check valve 9, solenoid directional control valve 10 are joined together to form first loop by tube connector, electromagnetic steering valve 3, cooler 13, the 4th check valve 4, the 11 check valve 11, winter, heater 12 was joined together to form second loop, and wherein winter, heater 12 was connected with fluid reservoir 7 one ends; Solenoid directional control valve 10, heat exchanger 1 and second check valve 2 form the 3rd loop.
Operating mode of the present invention has increased a cooler 13 exactly between heat exchanger 1 and expansion valve 5, the high pressure refrigerant in the heat exchanger 1 is cooled to mesolow by cooler 13, and to expansion valve 5 throttlings, cooler 13 has played the balanced action of high-low pressure.Solved in the prior art owing to there is not the cooling of cooler 13, the heat exchanger internal pressure is too high, causes the problem of compressor high voltage protective, the perfect conversion of compressor from the HTHP to the low-temp low-pressure.Therefore, when the delivery temperature of compressor 8 was in 80-120 ° of scope, compressor 8 can both normal operation.
Winter of the present invention, heater 12, be the heat energy that is taken to air by refrigerant in the heat exchanger 1 by the heater 12 anti-compressors 8 of giving in winter, improve the delivery temperature of compressor 8, improve the Energy Efficiency Ratio of heat pump in winter, reached energy-conservation effect.
Heat pump operating mode system among the present invention, adopted summer in winter two different operating mode systems to come work, solve the contradiction that shares an operating mode job in the prior art in two seasons of summer in winter, remedied because the system condition deficiency that the variation of environment temperature causes, improved the efficient of heat pump.
