Background technology
Traditional air-cooled heat pump unit, the mode that heats as a kind of energy-conserving and environment-protective has obtained application in non-heating regions such as China middle and lower reach of Yangtze River, south China.But in vast heating areas such as China Huanghe valley, North Chinas, in the winter of cold, because pressure ratio is big, refrigerant flow is low, and the heating capacity of traditional air-cooled heat pump unit is decayed significantly, can't satisfy the requirement of heat supply heating, also can't reliability service.Traditional air-cooled heat pump air-conditioning system generally can only be used under the environment more than-5 ℃.The only tonifying Qi when heating of air source heat pump of tonifying Qi in the middle of the existing employing flash vessel to improve the heating performance of system, can be operated under the environment about-15 ℃.But because the existence of middle gas supplementing opening, the efficiency when making refrigeration has certain reduction.Therefore, press for a kind of heating performance that can either improve system of exploitation, can improve the energy saving and environment friendly air-cooled heat pump unit of the refrigeration performance of system again.
Summary of the invention
At the problem of above-mentioned existence, proposed one and overlapped the source pump that is applicable to the employing flash vessel bidirectional air compensation on the novel scroll compressor.Increase the stability of heat pump operation and expanded the heat pump scope of application; Improved heating and refrigeration performance of system simultaneously.Make designs simplification again, cost reduces.
To achieve the above object, technical scheme of the present invention realizes as follows: the exhaust outlet of compressor links to each other with the D mouth of reversal valve, the S mouth of reversal valve links to each other with the air entry of compressor through gas-liquid separator, the C mouth of reversal valve links to each other with the gas port of air cooling heat exchanger, the E mouth of reversal valve links to each other with the gas port of user side heat exchanger, it is characterized in that: the liquid mouth of air cooling heat exchanger links to each other with an end of first throttle device by first filter, the other end of first throttle device links to each other with a liquid mouth of two-way flash vessel, another liquid mouth of two-way flash vessel links to each other with an end of second throttling arrangement, the other end of second throttling arrangement links to each other with an end of second filter, the other end of second filter directly or by two-way reservoir links to each other with the liquid mouth of user side heat exchanger, and the gas port of two-way flash vessel links to each other with the gas supplementing opening of compressor.
In the gas supplementing opening of compressor or outside the gas supplementing opening, check valve is set.When check valve was positioned at gas supplementing opening, the gas port of two-way flash vessel directly was connected with the gas supplementing opening of compressor; In the time of outside check valve is positioned at gas supplementing opening, the gas port of two-way flash vessel is connected with check valve.
The gas supplementing opening of the gaseous refrigerant that produces after the throttling of first throttle device being defeated by compressor is as middle tonifying Qi, to realize the bidirectional air compensation of refrigerating/heating.The size of utilizing the first throttle device and second throttling arrangement to regulate the air compensation of compressor.The described first throttle device and second throttling arrangement comprise: the one or more combination in electric expansion valve, heating power expansion valve, the capillary.
Core of the present invention is to have adopted two-step throttle, and the gaseous refrigerant that produces after the first order throttling is defeated by the compressor gas supplementing opening as middle tonifying Qi, has realized the refrigerating/heating bidirectional air compensation.By regulating first throttle device, second throttling arrangement, the size that can regulate air compensation realizes the high efficient and reliable operation of system.
