Air conditioner and its control method and device

Abstract

The present application discloses an air conditioner and its control method and device, wherein the control method may include the following steps: when the air conditioner is running in the automatic temperature recovery mode, obtain the return air temperature and the outlet air temperature of the indoor unit; Return air temperature and outlet air temperature, control to reduce the return air temperature of the indoor unit to be less than or equal to the set temperature; continue to obtain the return air temperature and outlet air temperature; if continue to obtain the temperature difference between the return air temperature and the outlet air temperature If it is within the preset first temperature range, the operating frequency of the compressor is controlled to be reduced, so as to increase the return air temperature to be within the preset second temperature range. Therefore, when the air conditioner is running in the automatic temperature recovery mode, it can accurately and effectively control the indoor temperature to drop below the set temperature first to meet the needs of users, and after maintaining it for a period of time, the indoor temperature can be accurately and effectively recovered A certain temperature can avoid the cold feeling caused by the low surface temperature of the human body, thus greatly improving the user experience.

Description

technical field [0001] The present application 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] In related technologies, the indoor temperature is generally detected by an indoor temperature sensor disposed at the return air outlet of the indoor unit of the air conditioner, and the air conditioner is controlled accordingly according to the detected indoor temperature. However, the air conditioner cannot be accurately controlled through the above method, so that the user cannot be provided with a comfortable ambient temperature in a timely and accurate manner, which greatly affects the user's experience. Contents of the invention [0003] The embodiment of the present application provides an air conditioner and its control method and device, which solves the problem that in the prior art, when the air conditioner is running in the au...
