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.
