Problems solved by technology

[0003] In method 1), the compressor needs to be stopped twice due to the need for reversing, resulting in a long defrosting time, and the suction temperature of the compressor is extremely low during defrosting
A large amount of liquid refrigerant entering the compressor will easily cause liquid shock and affect the life of the compressor

Embodiment 1

[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 member 7 is controlled to communicate with the second interface j, and the first connection port e of the third reversing member 9 is controlled to connect to the third connection The port g is connected so that the refrigerant flows 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 not needed, the heat accumulator 6 is stored until the preset condition is met. During heat storage, the first interface h is connected to the third interface i, and the refrigerant flows through the first heat exchange tube 61 for heat storage.

[0125] In heating mode, when it is determined that defrosting is required, it will enter defrosting ...

Embodiment 2

[0129] Such as Figure 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 cooling mode, control the first interface h of the second reversing member 7 to communicate with the second interface j, and control the first connection port e of the third reversing member 9 to communicate with the second connection port f, The heating device 63 is controlled to be closed.

[0132] After the refrigerant flows out through the second end of the outdoor heat exchanger 3, it flows into the first throttling part 4 for throttling. Taking the first throttling part 4 including a cooling throttling part 42 and a heating throttling part 41 as an example, the refrigerant flows into The cooling throttling part 42 performs throttling, flows into the indoor heat exchanger 8 through the second interface j and the first interface h of the second reversing member 7, evaporates and ab...

Abstract

The invention provides an air conditioner, a control method thereof, a control device and a computer readable storage medium. A heat accumulator comprises a first heat exchange tube and a second heatexchange tube, one end of the first heat exchange tube is connected with a third interface, the first heat exchange tube is connected with a first pipeline in parallel, and the second heat exchange tube is connected with a second pipeline in parallel. According to the air conditioner, in a defrosting mode, a first reversing element does not change the direction and can continuously supply heat tothe indoor, heating of the air conditioner is not influenced, and the use comfort of a user is not influenced. Due to the fact that the heat accumulator is arranged between a second end of an indoor heat exchanger and a second end of an outdoor heat exchanger, during heat storage, a refrigerant flows through the first heat exchange tube after flowing through the indoor heat exchanger, then the influence on the heating amount of the air conditioner during heat storage is small, the heat loss is reduced, and indoor temperature fluctuation is avoided.

Description

technical field [0001] The present invention relates to the field of refrigeration equipment, and more specifically, to an air conditioner, a control method thereof, a control device, and a computer-readable storage medium. Background technique [0002] There are mainly three traditional defrosting methods: 1) During the heating operation process of the air conditioner, the first reversing member switches to the refrigeration cycle, allowing the high-temperature and high-pressure refrigerant discharged from the compressor to enter the outdoor heat exchanger through the first reversing member, and defrost. 2) Bypass defrosting, without reversing, the high-temperature and high-pressure refrigerant discharged from the compressor directly enters the outdoor heat exchanger for defrosting without passing through the indoor unit. [0003] In method 1), the compressor needs to be shut down twice due to the need for reversing, resulting in a long defrosting time, and the suction tem...
