Air conditioner defrosting control method, air conditioner and computer readable storage medium

Abstract

The present invention provides an air conditioner defrost control method, air conditioner and computer-readable storage medium, the method comprising: entering the heating state; judging whether the following first entry defrosting conditions are met at the same time: the indoor temperature is detected continuously for the first preset duration The change value is less than or equal to the first preset temperature value; the difference between the current inner tube temperature and the highest inner tube temperature in the current defrosting cycle is less than or equal to the second preset temperature value; if the first defrosting condition is met at the same time, Then enter the defrosting state. The air conditioner defrosting control method of the present invention can be combined with the heat load demand of the room to control the air conditioner to enter the defrosting when the room temperature cannot be raised due to the attenuation of the capacity of the air conditioner due to frosting, so that the room temperature can be heated up quickly, and the heating comfort can be improved sex.

Description

technical field [0001] The present invention relates to the technical field of air conditioner defrosting, in particular to an air conditioner defrost control method, an air conditioner applying the air conditioner defrost control method, and a computer-readable storage medium applying the air conditioner defrost control method. Background technique [0002] When the household air conditioner heat pump air conditioner operates in a low temperature environment, the external heat exchanger is prone to frost. If it is not defrosted in time, it will affect the heating capacity and reliability of the air conditioner. The existing logic of the air conditioner control entering the defrosting usually has two One is to judge whether to enter the defrost according to the running time, and the other is to judge whether to enter the defrost according to the temperature of the outer tube and the external ambient temperature, but these two kinds of defrost will have the following problems:...

Problems solved by technology

[0002] When the heat pump air conditioner of a household air conditioner is heating and running in a low temperature environment, the heat exchanger of the external unit is prone to frost. If it is not defrosted in time, the heating capacity and reliability of the air conditioner will be affected. The logic of the existing air conditioner control to enter the defrost usually has two One is to judge whether to enter the defrost according to the running time, and the other is to judge whether to enter the defrost according to the temperature of the outer tube and the temperature of the external environment, but these two defrosts will have the following problems: the heat load of the room is not considered Demand, the defrosting process itself will cause the room temperature to drop, blowing cold wind and other problems, if the room temperature is not high, the defrosting will have a greater impact, making the user feel that the heating effect is not good

However, it does not take into account that when the heat load demand in the room is large, the heating capacity of the air conditioner cannot raise the room temperature after the frosting of the external unit causes the capacity to decline to a certain extent, but at this time the air conditioner has not yet met the defrosting conditions and continues to heat , which will cause the room to fail to quickly reach the comfortable temperature or the temperature set by the user, which will affect the heating comfort
