Abstract

The invention relates to the technical field of air conditioners, and discloses an expansion valve control method for an air conditioner. The control method comprises the following steps of periodically obtaining the real-time operation frequency of a compressor of the air conditioner; and controlling an expansion valve to open according to the real-time operation frequencies obtained in the two adjacent periods if the difference between the real-time operation frequencies obtained in the two adjacent periods meets a preset condition set based on the change rate of the operation frequency of the compressor of the air conditioner. According to the technical scheme, the real-time operation frequency of the compressor is periodically detected, and the opening degree of the expansion valve ofthe air conditioner is compensated on the basis of the real-time operation frequency obtained in the two adjacent periods, and thus the situation that the opening degree of the expansion valve of theair conditioner fails to reach the change rate of the operation frequency of the compressor, and consequently the air conditioner malfunctions is avoided.

Description

technical field [0001] The present application relates to the technical field of air conditioning, for example, relates to an expansion valve control method, device, electronic equipment and storage medium for air conditioning. Background technique [0002] The operating frequency of traditional air-conditioning compressors is increased at the initial start-up, and the frequency increase rate is usually slow during mode switching and frequency increase according to the ambient temperature, resulting in slow temperature change speed, poor user experience, and unable to meet user needs. In order to improve user experience, current air conditioners usually use frequency jump technology to adjust the operating frequency of the compressor. With the air conditioner adopting the frequency jump technology, the frequency increase rate of the compressor operation frequency is significantly increased, and the rate of adjusting the indoor temperature is faster, so that the indoor temper...
