Abstract

The invention discloses a control method for an air conditioner. The method comprises the following steps: S1, when the air conditioner is started for cooling, detecting indoor temperature T1, outdoor temperature T4, remote controller set temperature Ts and the running time of a compressor; S2, when T1 is higher than T1P, T4 is higher than T4d and lower than T4g, and DeltaT1s is more than T1sp, running the compressor at first frequency Frg, otherwise running the compressor at second frequency Fg, wherein Frg is higher than Fg; S3, after the compressor runs at the first frequency Frg for running time U1, running the compressor at the second frequency Fg when the running time of the compressor reaches total end time U2 or an end signal is detected by the air conditioner. According to the control method for the air conditioner, a room can be rapidly cooled, the compressor is prevented from working in a high-frequency state for a long time, and the service life of the compressor is prolonged.

Description

technical field

[0001] The invention relates to the field of household appliances, in particular to an air conditioner control method. Background technique

[0002] Most of the control methods for the operating frequency of the air conditioner compressor in the related art are based on the indoor return air temperature, the outdoor return air temperature and a certain algorithm to calculate the operating frequency of the compressor, while considering the long-term operation reliability of the compressor and the noise of the compressor. The frequency will be limited within a certain range. Because this control method does not take into account that when the air conditioner is just turned on for cooling operation, the use environment and the user’s cooling demand for the air conditioner is greater than when it is in stable operation, so various air conditioner manufacturers often receive complaints from consumers about the slow cooling speed.
