The specific embodiment
Below in conjunction with Fig. 1, the utility model is described further:
Air source high-temperature heat pump Hot water units mainly contains the critical pieces such as compressor 1, cross valve 2, high-performance heat exchanger 3, attemperater 4, circulating pump 5, fluid reservoir 6, filter 7, heating power expansion valve 8, magnetic valve 9, separator 10, blower fan 11 and evaporimeter 12 and forms.
All critical pieces connect to form the high temperature refrigerant circulatory system of an enclosed by copper pipe, flow process during its operation is followed successively by, evaporator fan 11 started operation after 10 seconds, circulating pump 5 brought into operation after 30 seconds, compressor 1 brings into operation, in the process of operation, absorb after the low-temperature low-pressure refrigerant of evaporimeter 12, compressor 1 becomes refrigerant compression the gaseous state of HTHP, its refrigerant temperature can reach 145 ℃, the cold-producing medium of HTHP starts release heat while flowing through high-performance heat exchanger 3 by cross valve 2, by circulating pump 5, drive the water in attemperater 4 to be recycled to high-performance heat exchanger 3, cold water is stored to flowing into attemperater 4 between 100 ℃ by one-time heating to 90 ℃.
There is gas-liquid mixed state in the reduction of high-temperature high-pressure refrigerant temperature, when cold-producing medium is flowed through fluid reservoir 6, fraction liquid refrigeration device is stored, most of gaseous refrigerant is when flowing through filter 7, impurity in cold-producing medium further cleans, the stability of enhancing system, intrasystem cold-producing medium becomes the gaseous state of low-temp low-pressure after damming by thermal expansion 8, and minimum temperature reaches-30 ℃.
Low-temp low-pressure refrigerated medium is when through evaporimeter 12; by blower fan 11, constantly drive air by evaporimeter 12; air and evaporimeter 12 internal refrigeration storage agent are carried out heat exchange in the effect of the temperature difference; the temperature of air further reduces outside discharge chamber; low-temperature refrigerant heat absorption forms liquid state; by cross valve 2, get back to separator 10; sub-fraction liquid refrigerant is stored; most of cryogenic gaseous cold-producing medium is got back to compressor 1 again; iterative cycles like this, the temperature of attemperater 4 reaches design temperature and shuts down.Hot water in attemperater is during lower than design temperature, and main frame can start heating automatically.
When in the process that main frame is moving, system pressure is too high, magnetic valve 9 can be opened automatically, impels main frame can not shut down because of hypertonia, makes the stable operation of main frame energy.When hot water is used, only the hot water in attemperater need to be retracted to and use hot water to make a little.
Owing to having adopted high temperature mix refrigerant and high-efficiency multi-stage heat exchanger, the high-temperature high-pressure refrigerant that high temperature refrigerant extrudes by compressor is fully heat exchange in high-performance heat exchanger, cascade raising temperature, thereby temperature constantly raises in heat exchanger, by regulating flow of inlet water to reach once more than water heat exchange to 90 ℃.Its energy-conservation relative electric heater reaches more than 2.5 times.
Air source high-temperature heat pump Hot water units adopts high temperature mix refrigerant R134, R142B, R22, its mixed proportion is 5:3:2, the high-performance heat exchanger of cold-producing medium by main frame is repeatedly after heat exchange, water temperature can disposablely rise between 90-100 degree, can adjusting water outlet temperature by the shutoff valve of main frame inside.
By reference to the accompanying drawings the utility model has been carried out to exemplary description above; obvious realization of the present utility model is not subject to the restrictions described above; as long as the various improvement that adopted method design of the present utility model and technical scheme to carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all in protection domain of the present utility model.
