Abstract (en)
[origin: EP3734167A1] An air conditioner system, comprising a compressor (1), an indoor heat exchanger (2), a first throttle device (3), and an outdoor heat exchanger (4) connected in series in a main circuit. The main circuit is also provided with a heat exchanger (5) and a first gas-liquid separator (6). A bypass defrosting circuit (P) is disposed between the compressor (1) and the outdoor heat exchanger (4). One side of the heat exchanger (5) is connected to a first pipeline (M) between the first throttle device (3) and the indoor heat exchanger (2), and the other side of the heat exchanger (5) is connected to a second pipeline (N) between the first throttle device (3) and the outdoor heat exchanger (4). A refrigerant passing through the first pipeline (M) and a refrigerant passing through the second pipeline (N) can exchange heat in the heat exchanger (5). A bypass pipeline (L) is disposed between the first gas-liquid separator (6) and the compressor (1). The air conditioner system can achieve the purpose of defrosting without being turned off while increasing the degree of supercooling of the refrigerant in the first pipeline (M).
