Embodiment 1
[0054] Such as figure 1As shown, the air conditioner system includes a connected compressor unit, an air supply device 30, an indoor unit 40, an outdoor unit 50 and a defrosting pipeline 80, wherein the compressor unit includes a plurality of working chambers, and at least one of the plurality of working chambers The working chamber communicates with the air supply device 30 through the air supply pipeline 70; the first end of the defrosting pipeline 80 communicates with the outdoor unit 50, and the second end of the defrosting pipeline 80 can optionally communicate with at least one of the multiple working chambers. The working chamber is connected. When the outdoor unit 50 reaches the defrosting preset value, the defrosting pipeline 80 is controlled to communicate with the working chamber, so that the refrigerant enters the outdoor unit 50 through the defrosting pipeline 80 for defrosting operation. The compressor unit does not stop when the system enters the defrosting oper...
Embodiment 2
[0064] Such as figure 2 As shown, the difference between this embodiment and Embodiment 1 is that the multiple working chambers include a first working chamber 11 and a second working chamber 14, and the first working chamber 11 has a first suction port 12 and a first exhaust port 13 , the second working chamber 14 has a second suction port 15 and a second exhaust port 16, the first suction port 12 can be selectively communicated with at least one of the air supply device 30 and the second exhaust port 16, the second One exhaust port 13 communicates with the indoor unit 40, the second air intake port 15 communicates with the liquid outlet of the liquid storage device 20, and the second end of the defrosting pipeline 80 connects the first air intake port 12 with the second The second pipeline 17 of the exhaust port 16 is connected.
[0065] Such as figure 2 As shown, the compressor unit includes a second compressor 10 having a first working chamber 11 and a second working c...
Embodiment 3
[0068] Such as image 3 As shown, the difference between this embodiment and the second embodiment is that the compressor unit includes a third compressor 400 and a fourth compressor 500, the third compressor 400 has a first working chamber 11, and the fourth compressor 500 has a second working chamber cavity 14 , the third compressor 400 has a second gas supply port 410 .
