Description of drawings:
Fig. 1 is a structural representation of the present utility model
The specific embodiment
A kind of double-compressor heat pump water-heating machine, it comprises the ordinary hot pump installation that a stage compressor 1, cross valve 3, check valve 4, water-side heat 11, high pressure fluid reservoir 7, filter 8, cooler 9, throttling arrangement 12, air-side heat exchanger 6, gas-liquid separator 5, pipeline constitute, also include split-compressor 2, a split-compressor 2 and a stage compressor 1 are connected in parallel.One stage compressor 1 connect successively check valve 4, cross valve 3 wherein two interfaces, water-side heat 11, check valve 40, high pressure fluid reservoir 7, filter 8, cooler 9, throttling arrangement 12, check valve 43, air-side heat exchanger 6, cross valve 3 two interfaces, gas-liquid separator 5, stage compressors 1 are communicated with into the loop in addition; Split-compressor 2 is in parallel with a stage compressor 1, before cross valve 3 with a stage compressor 1 connect successively identical.One check valve 44 is set between gas-liquid separator 5 and split-compressor 2, a check valve 42 is set between air-side heat exchanger 6 and the high pressure fluid reservoir 7, between throttling arrangement 12 and water-side heat 11, be provided with check valve 41.
When heating condition,, only need to open a compressor if heat demand is little.As open a stage compressor 1, the gaseous refrigerant of low-temp low-pressure is collapsed into the gaseous refrigerant of HTHP by a stage compressor 1, wherein two interfaces through check valve 4, cross valve 3 enter water-side heat 11, gaseous refrigerant release heat cooling at this HTHP becomes highly pressurised liquid, realizes heating purpose; High pressure refrigerant liquid enters in the high pressure fluid reservoir 7 through check valve 40, by the high pressure liquid refrigerant process filter 8 of high pressure fluid reservoir 7 outflows and the highly pressurised liquid passage of cooler 9, enter the gas-liquid two-phase cold-producing medium of throttling arrangement 12 throttling step-downs becoming low-temp low-pressure, throttling arrangement 12 can be a heating power expansion valve, it can be electric expansion valve, it also can be capillary, enter in the hot side heat exchanger 6 of air through check valve 43 again, liquid refrigerant evaporation absorption chamber outer air heat becomes the gaseous refrigerant of low-temp low-pressure, in addition two interfaces of cross valve 3 of flowing through again enter gas-liquid separator 5 and return a stage compressor 1, finish heating circulation.
Can only open split-compressor 2, the gaseous refrigerant of low-temp low-pressure is collapsed into the gaseous refrigerant of HTHP by split-compressor 2, wherein two interfaces through cross valve 3 enter water-side heat 11, route identical when process is with unlatching one stage compressor then arrives gas-liquid separator 5, return split-compressor 2 through check valve 44 again, finish heating circulation.
When heat demand is bigger, open two compressors, open a stage compressor 1 earlier, open split-compressor 2 after 5～10 seconds subsequently, firsts and seconds compressor parallel operation this moment.The gaseous refrigerant of low-temp low-pressure is collapsed into the gaseous refrigerant of HTHP respectively by a stage compressor 1 and split-compressor 2, before cross valve 3, converge through check valve 4 with by the gaseous refrigerant of the HTHP of split-compressor 2 compressions by the high temperature and high pressure gaseous refrigerant of a stage compressor 1 compression, arrive gas-liquid separator 5 through route identical when only opening a stage compressor 1 then, this moment, the gaseous refrigerant of low-temp low-pressure was divided into two-way, one the tunnel directly returns a stage compressor 1, split-compressor 2 is returned through check valve 44 in another road, finish heating circulation, circulation makes heat continually and so forth.
When machine moves in the winter time, when the coil pipe of air-side heat exchanger 6 enters the defrost temperature of setting, control system is regulated cross valve 3 automatically and is turned to, make the cold-producing medium antikinesis, the gaseous refrigerant of low-temp low-pressure is collapsed into the gaseous refrigerant of HTHP by a stage compressor 1 at this moment, in addition two interfaces of warp-wise valve 4, cross valve 3 flow in the air-side heat exchangers 6, through the outdoor air cooling and condensation becomes highly pressurised liquid, again by entering in the high pressure reservoir 7 to valve 42; The flow through highly pressurised liquid passage of filter 8 and cooler 9 of the high pressure liquid refrigerant that flows out by high pressure receiver 7, through throttling arrangement 12 (can be heating power expansion valve, it can be electric expansion valve, also can be capillary) the throttling step-down becomes the gas-liquid two-phase cold-producing medium of low-temp low-pressure, and enter water-side heat 11 through check valve 41, absorb the gaseous refrigerant that heat of vaporization becomes low-temp low-pressure at this liquid refrigerant, realize the defrost purpose, the gaseous refrigerant of low-temp low-pressure enters gas-liquid separator 5 through wherein two interfaces of cross valve 3 and returns low-pressure stage compressor 1, finishes defrost process.
Certainly, the embodiment of the above, it is preferred embodiments of the present utility model, be not to limit the utility model practical range, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and are included in the utility model claim.
