Embodiment Construction

[0040] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0041] The invention provides a defrosting method for an air conditioner.

[0042] refer to figure 1 , figure 1 It is a schematic flowchart of the first embodiment of the defrosting method for the air conditioner of the present invention.

[0043] The present invention proposes a first embodiment of a defrosting method for an air conditioner. In this embodiment, the defrosting method of the air conditioner includes the following steps:

[0044] Step S10, when the outdoor unit of the air conditioner operates at partial load, obtain the working status information of all heat exchangers of the outdoor unit;

[0045] Define the working state as the first heat exchanger, and the idle state as the second heat exchanger.

[0046] Step S20, acquiring frosting state information of the first heat exchanger;

[0047] Step ...

Abstract

The invention discloses a defrosting method for an air conditioner. The method includes the following steps that when a running part of an air conditioner outdoor unit bears loads, working state information of all heat exchangers of the outdoor unit is obtained; frosting state information of the first heat exchanger is obtained; when the frosting state information of the first heat exchanger reaches a preset defrosting condition, the first heat exchanger with the frosting state information reaching the preset defrosting condition is replaced by the second heat exchanger for heat exchange operation. The invention further discloses a defrosting device for the air conditioner and the air conditioner outdoor unit. By means of the defrosting method for the air conditioner, the defrosting time interval is prolonged, and the influences on the indoor air temperature in the air conditioner defrosting process are reduced.

Description

technical field [0001] The invention relates to the technical field of air conditioner control, in particular to an outdoor unit of an air conditioner, a method for defrosting an air conditioner and a device thereof. Background technique [0002] An air conditioner is a common household appliance. When the air conditioner operates in heating mode in winter, the surface temperature of the outdoor heat exchanger is lowered because the refrigerant evaporates and absorbs heat in the outdoor heat exchanger. If the air conditioner continues to operate in heating mode when the outdoor temperature is extremely low, a large amount of frost may condense on the surface of the outdoor heat exchanger, thereby affecting the normal operation of the air conditioner. [0003] When the existing air conditioner defrosts, the air conditioner is switched to the cooling mode, and the refrigerant condenses and releases heat in the outdoor heat exchanger, which increases the surface temperature of...
