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 4):
The method of controlling gas replenishment of a two-stage compression air conditioning system according to  claim 2 , wherein the control of the stop valve according to the superheat degree SH of replenished gas and the front-rear temperature difference TH of the gas replenishing valve comprises:\n determining an 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; and controlling the stop valve according to the operation state of gas replenishment, wherein the operation state of gas replenishment comprises normal forward flow of replenished gas, back flow of replenished gas, or forward flow of replenished gas with liquid.
