Heat process: the cold-producing medium that compressor is discharged directly enters in the evaporimeter through return duct, because second throttling arrangement is at the back near-end of evaporimeter, cold-producing medium is fully heat release in evaporimeter, improves heating capacity, and the cold-producing medium after the heat release arrives the first throttle device through carrier pipe; Cold-producing medium is got back to condenser through the first throttle device again, gets back to compressor after the heat exchange through the condenser and the external world, finishes one and heats circulation.
Advantage of the present invention is:
1. the present invention is owing to be provided with first and second throttling arrangements respectively, from the carrier pipe of cold-producing medium between condenser and evaporimeter that condenser comes out, still keep liquid during refrigeration, the gaseous refrigerant that makes same compressed machine discharge has bigger space to carry out sufficient heat exchange in condenser, can alleviate the load of compressor, improve the Energy Efficiency Ratio of air-conditioning.
2. first throttle device of the present invention has slowed down the flow velocity of cold-producing medium, and the high temperature refrigerant gas that makes compressor come out stops the longer time to carry out heat exchange fully with outdoor environment in condenser, makes that the refrigerant temperature cooling is more abundant; The cold-producing medium of process carrier pipe is once more by the second throttling arrangement throttling, and control enters the evaporation capacity of the cold-producing medium of evaporimeter, obtains best refrigeration.When heating, the cold-producing medium that compressor is discharged directly enters in the evaporimeter through return duct, and owing to the back near-end of second throttling arrangement at evaporimeter, cold-producing medium is fully liquefaction heat release in evaporimeter, reaches to heat purpose.
