Abstract:
Described is a two-stage compression air conditioning system and a method of controlling gas replenishment thereof. The two-stage compression air conditioning system includes a two-stage compressor and a flash evaporator, wherein a first port of the flash evaporator is connected to one end of a stop valve by a first pipeline and the other end of the stop valve is connected to a first gas intake of the two-stage compressor by a second pipeline. The method of controlling gas replenishment includes: obtaining a first temperature value and an intermediate pressure value in the first pipeline, and a second temperature value in the second pipeline; and controlling the stop valve according to the first temperature value, the intermediate pressure value and the second temperature value.

Claim (Index 5):
The method of controlling gas replenishment of a two-stage compression air conditioning system according to  claim 4 , wherein the determination of the operation state of gas replenishment according to the superheat degree SH of replenished gas and the front-rear temperature difference TH of the gas replenishing valve comprises:\n determining the operation state as normal forward flow of replenished gas, if SH\u2265a and TH\u2265b; determining the operation state as back flow of replenished gas, if SH\u2265a and TH<b, or if SH<a and TH<c; and determining the operation state as forward flow of replenished gas with liquid, if SH<a and TH\u2265c; wherein a, b and c are all preset values.
