Embodiment 1
[0119] Such as Figure 8 As shown, the control methods include:
[0120] Step S80 , in the heating mode, when it is determined that defrosting is required, the first connecting port e of the second reversing member 7 is controlled to communicate with the third connecting port g.
[0121] In the control method provided by the embodiment of the second aspect of the present invention, in the heating mode, when it is determined that defrosting is required, the defrosting mode is entered. In the defrosting mode, the first connection port e is connected to the third connection port g, and the refrigerant discharged from the exhaust port 11 of the compressor 1 flows into the outdoor heat exchanger 3 through the indoor heat exchanger 8 and the first heat exchange pipe 61 , the refrigerant releases heat in the outdoor heat exchanger 3, and defrosts the outdoor heat exchanger 3. After defrosting, it enters the second heat exchange tube 62 through the first connection port e and the thi...
Embodiment 2
[0133] Control methods include:
[0134] In the heating mode, when it is determined that defrosting is not needed, the first connection port e of the second reversing member 7 is controlled to communicate with the second connection port f.
[0135] The first connection port e communicates with the second connection port f, and the refrigerant does not flow through the second heat exchange tube 62 . In the heating mode, when it is determined that defrosting is not needed, the refrigerant does not flow through the second heat exchange tube 62, and the air conditioner performs normal heating. When the air conditioner is in heating operation, the heat accumulator 6 stores heat.
[0136] In one embodiment, in the heating mode, when it is determined that defrosting is not required, the first connection port e of the second reversing member 7 is controlled to communicate with the second connection port f, and it also includes: controlling according to the working condition parameters...
