Air conditioner, air conditioner control method and device, and readable storage medium

Abstract

The invention discloses an air conditioner control method. The method comprises the steps that when the air conditioner is in a self-cleaning mode, the air conditioner is controlled to operate for refrigeration, and condensation and frosting of the air conditioner are completed; after frosting on the surface of a heat exchanger is completed, the air conditioner is controlled to operate for heating; after the surface of the heat exchanger is defrosted, an ambient temperature and a coil temperature of the heat exchanger are acquired; and according to the coil temperature and the ambient temperature, the rotation speed of a fan of the heat exchanger is adjusted. The invention further discloses an air conditioning control device, the air conditioner and a readable storage medium. The inventionaims to improve the efficiency of the fan cooling heat exchanger in the self-cleaning process of the air conditioner and reduce the energy loss.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner control method, an air conditioner control device, an air conditioner and a readable storage medium. Background technique [0002] Most of the existing air conditioners use tube-fin heat exchangers, and pollutants such as dust in the air are easy to adhere to the fins, and will continue to accumulate into dirt with the use of the air conditioner. The formation of dirt will increase the heat transfer resistance of the fins, reduce the heat transfer efficiency of the heat exchanger, and at the same time nourish bacteria and affect air quality. Therefore, the heat exchanger needs to be cleaned regularly during the use of the air conditioner, and the self-cleaning function of the air conditioner came into being. [0003] The self-cleaning process of the air conditioner generally includes steps such as condensation, frosting, and defrosting. Among them, i...

Problems solved by technology

Among them, in the defrosting stage, the heating operation is generally used for defrosting. After the defrosting stage, the temperature of the cleaned heat exchanger is relatively high. Most air-conditioning products generally exit the heating operation and control the fan of the cleaned heat exchanger to Running at a fixed speed for a fixed length of time to cool down the heat exchanger, but this method is likely to cause low cooling efficiency in high-temperature environments, and the cooling effect that a fixed speed can achieve is limited when the temperature of the heat exchanger is not much different from the ambient temperature , resulting in energy waste, therefore, the current fan cooling heat exchanger cooling efficiency is low and wastes energy
