Abstract (en)
[origin: EP3734193A1] An air conditioner system, comprising a compressor (1), an indoor heat exchanger (2), a first throttling apparatus (3), and an outdoor heat exchanger (4) connected in series in a main loop. A heat exchanger (5) is further provided in the main loop; one side of the heat exchanger (5) is connected to a first pipeline (M) between the first throttling 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 throttling 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 carry out heat exchange in the heat exchanger (5). Therefore, not only the degree of supercooling of the refrigerant in the first pipeline (m) is effectively increased, evaporation of the refrigerant of the second pipeline (n) can be promoted, and thus the heating capacity of the system is improved.
