Multifunctional heat pump system

[0029] Embodiment 1: Take the heat pump module in the second heat pump unit B for the cooling process, the heat pump module in the first heat pump unit A performs the bypass adjustment process as an example, that is, in the second heat pump unit B as the cooling process The refrigeration compressor in the heat pump module is running, and the refrigeration compressor in the heat pump module A in the first heat pump unit A of the bypass adjustment process is stopped. The bypass adjustment process includes: (1), hot air bypass to the energy-regulated thermodynamic cycle at the suction end of the refrigeration compressor; (2) hot air bypass to the energy-regulated thermodynamic cycle at the entrance of the indoor heat exchanger; (3), hot air bypass The energy mixed at the suction end of the compressor and the inlet of the indoor heat exchanger adjusts the thermodynamic cycle. The first valve 7, the second valve 8, the third valve 9 and the fourth valve 10 in the heat pump modules in t

[0035] Embodiment 2: Take the second heat pump unit B for the heating process, the first heat pump unit A for the bypass adjustment process or the outdoor heat exchanger defrosting process as an example, that is, the second heat pump unit as the heating process The refrigeration compressor in the heat pump module in B operates, and the refrigeration compressor in the heat pump module in the heat pump module A in the first heat pump unit A is stopped as a bypass adjustment process or an outdoor heat exchanger defrosting process. The bypass and defrost process are: (1) hot gas bypass to the energy-regulated thermodynamic cycle at the suction end of the refrigeration compressor; (2) hot gas bypass to the energy-regulated thermodynamic cycle at the entrance of the outdoor heat exchanger; (3) hot gas bypass The energy mix at the suction end of the compressor and the entrance of the outdoor heat exchanger to adjust the thermodynamic cycle; (4) Defrost cycle of the outdoor heat exchanger.
