But the system still has obvious disadvantages: for example, the system needs both heating and cooling. The ambient temperature range of the applicable occasion is from -15°C to +43°C, and the corresponding refrigerant will be at -25°C--+ Evaporation work within a temperature range of 5°C, due to the functional and performance limitations of the thermal expansion valve used, this full temperature range operating condition is not competent for a single thermal expansion valve, and the system can only succumb to thermal power when matching design The expansion valve adopts an independent expansion valve system for cooling mode and heating mode, which will inevitably increase the complexity and manufacturing cost of the system, increase the operat

Embodiment Construction
[0008]In the main heating (or cooling) circuit of the system, the exhaust port of the jet booster compressor B (34) is connected to the D2 pipe port of the four-way reversing valve B (25), and the high-pressure switch B ( 26). The C2 pipe mouth of the four-way reversing valve B (25) is connected with the air inlet when the water side shell and tube heat exchanger B (27) condenses. The liquid outlet of the water-side shell-and-tube heat exchanger B (27) when condensing is connected with the liquid inlet of the refrigerant subcooling chamber of the economizer B (42) when the system is heating. When the system is heating, the liquid outlet of the refrigerant subcooling chamber of the economizer B (42) is connected with the liquid inlet of the liquid storage tank B (43) when the system is heating. When the system is heating, the liquid outlet of the liquid storage tank B (43) is connected in series with the dry filter B (40), the electronic expansion valve (41), the pipeline filt...

Abstract
The invention belongs to the field of steam compression type air source heat pumps and provides a heating and refrigeration vortex type air source heat pump system comprising a four-way reversing valve B, a high-pressure switch B, a water side shell and tube heat exchanger B, an exhaust temperature sensor B, an electromagnetic valve C, a fan B, a fin temperature sensor B, an air side fin heat exchanger B, a check valve F, an enhanced vapor injection compressor B, a low-pressure switch B, an air-liquid separator B, a pipeline filter, a check valve G, an electromagnetic valve D, a dry filter B,an electronic expansion valve, an economizer B, a liquid storage tank B, an electromagnetic valve E and other parts. With application of the heating and refrigeration vortex type air source heat pumpsystem, 1, the idea that refrigeration, heating and air supply of the heating and refrigeration vortex type air source heat pump system share the one electronic expansion valve is achieved, complexityand manufacturing cost are lowered, and full-working-condition refrigerating capacity and COP are promoted by 5% or above; and 2, during reverse cycle defrosting of the heating and refrigeration vortex type air source heat pump system, a refrigerant does not pass through the electronic expansion valve for throttling cooling and directly enters the water side shell and tube heat exchanger for heatexchange, room comfort is improved, and defrosting time is shortened by 5 seconds or above.
