WIPO Patent Application WO/2019/128517

A1

Disclosed is an air-conditioner system, comprising a compressor (1), an indoor heat-exchanger (2), a first throttling device (3) and an outdoor heat-exchanger (4) connected in series to a main circuit, with a heat exchange device (5) being further provided in the main circuit. A pipe between the first throttling device (3) and the indoor heat-exchanger (2) serves as a first pipe M, a pipe between the first throttling device (3) and the outdoor heat-exchanger (4) serves as a second pipe N, one side of the heat exchange device (5) is connected to the first pipe M, and the other side of the heat exchange device (5) is connected to the second pipe N. The first pipe M passes through one side of the heat exchange device (5), and the second pipe N passes through the other side of the heat exchange device (5). A refrigerant passing through the first pipe M and a refrigerant passing through the second pipe N can exchange heat in the heat exchange device (5). A first gas-liquid separator (6) is further provided in the main circuit, wherein the first gas-liquid separator (6) is located in a section of the second pipe N between the heat exchange device (5) and the outdoor heat-exchanger (4), and a bypass pipe L is provided between the first gas-liquid separator (6) and the compressor (1).
