Example Embodiment
[0121] Example one:
[0122] Such as Figure 8 As shown, the control methods include:
[0123] Step S802, in the heating mode, it is determined that defrosting is required, the first interface h of the second reversing element 7 is controlled to communicate with the second interface j, and the first connection port e of the third reversing element 9 is controlled to be connected to the third The port g is connected to allow the refrigerant to flow through the second heat exchange tube 62.
[0124] 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 unnecessary, the heat accumulator 6 is stored until the preset condition is satisfied. When storing heat, the first interface h is connected to the third interface i, and the refrigerant flows through the first heat exchange tube 61 to store heat.
[0125] In heating mode, when it is determined that defrosting is needed, enter the defr...
Example Embodiment
[0128] Embodiment two:
[0129] Such as Picture 9 As shown, the control method includes steps S902-S912.
[0130] Step S902, detecting the current operating mode of the air conditioner;
[0131] Step S904, if it is in the cooling mode, control the first interface h and the second interface j of the second reversing element 7 to communicate, and control the first connection port e of the third reversing element 9 to communicate with the second connection port f, The heating device 63 is controlled to turn off.
[0132] After the refrigerant flows out through the second end of the outdoor heat exchanger 3, it flows into the first throttling component 4 for throttling. Taking the first throttling component 4 including the cooling throttling component 42 and the heating throttling component 41 as an example, the refrigerant flows in The refrigeration throttling component 42 performs throttling, flows into the indoor heat exchanger 8 through the second interface j and the first interface...
