Abstract

The invention provides an air conditioner and a control method and device thereof. The control method includes the steps that when the air conditioner is in heating running, the frosting amount of an outdoor unit heat exchanger of the air conditioner is acquired; whether the frosting amount is larger than a preset value or not is judged; when the frosting amount is larger than the preset value, the air conditioner is controlled to get into a defrosting mode. According to the control method of the air conditioner, whether defrosting is started or not is judged according to the frosting amount, generated when the air conditioner is in heating running, of the outdoor unit heat exchanger, and when the frosting amount exceeds a certain threshold value, the air conditioner is controlled to start defrosting; due to the fact that the frosting amount is directly used as a judgment basis, the accuracy of defrosting start judgment of the air conditioner is effectively improved, the problems that in the prior art, a defrosting start signal source of an air conditioner is fuzzy, and start of the defrosting mode cannot be precisely controlled are solved, and then the defrosting efficiency of the air conditioner during low-temperature heating is effectively improved.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an air conditioner control method, an air conditioner control device and an air conditioner. Background technique [0002] At present, when the air conditioner is heating in winter, condensation and frost will inevitably occur on the heat exchanger of the outdoor unit, and in severe cases, ice crystals will appear, resulting in a decrease in the heating efficiency of the air conditioner. At present, there are two types of actual defrosting judgments for household air conditioners: 1) Timed defrosting, that is, the defrosting mode is turned on after the air conditioner runs continuously for a fixed time; 2) According to the temperature difference of the thermometer of the indoor unit heat exchanger or the outdoor unit heat exchanger to judge defrosting. Among them, the first type is mostly used for fixed frequency machines, and the second type is mostly used for ...
