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 .

Abstract

The invention provides an air conditioner system, an air conditioner and a defrosting control method of the air conditioner. The air conditioner system comprises a compressor unit, an air supply device, an indoor unit, an outdoor unit and a defrosting pipeline which communicate with one another; at least one working cavity of a plurality of working cavities of the compressor unit is provided withan air suction port and an air exhaust port, the air suction port communicates with the air supply device, and the exhaust port communicates with the indoor unit; and the first end of the defrosting pipeline communicates with the outdoor unit, the second end of the defrosting pipeline selectively communicates with at least one working cavity of the plurality of working cavities, and when the outdoor unit reaches a defrosting preset value, the defrosting pipeline is controlled to communicate with the working cavities, so that a refrigerant enters the outdoor unit through the defrosting pipelinefor defrosting operation. According to the air conditioner system, the problems that in the prior art, an air conditioner usually needs to start and stop a compressor many times to complete defrosting operation, heat is absorbed from the interior of a room, the indoor temperature is reduced, and the good user experience of a user on the air conditioner is greatly influenced are solved.

Description

technical field [0001] The invention relates to the technical field of air conditioner equipment, in particular to an air conditioner system, an air conditioner and a defrosting control method for the air conditioner. Background technique [0002] In the prior art, after the air conditioner is heated for a long time, a frost layer will be formed on the outdoor unit, which seriously affects the heat exchange efficiency of the outdoor unit. In order to remove the frost layer on the outdoor unit, the existing air conditioner usually needs to turn the air conditioner Switch the mode to cooling mode to ensure that the refrigerant can absorb heat from the room, and the refrigerant after absorbing heat enters the outdoor unit for exothermic defrosting. However, the above defrosting method needs to start and stop the compressor several times to complete the defrosting operation. , which greatly reduces the service life of the compressor; in addition, because the above-mentioned defr...
