Air conditioner and control method and device thereof

Abstract

The invention discloses an air conditioner and a control method and device thereof. The control method can comprise the following steps that when the air conditioner runs in an automatic temperature rise mode, the air return temperature and the air outlet temperature of an indoor unit are obtained; according to the air return temperature and the air outlet temperature of the indoor unit, the air return temperature of the indoor unit is controlled to be smaller than or equal to the set temperature; the air return temperature and the air outlet temperature are continuously obtained, and if the temperature difference between the continuously-obtained air return temperature and air outlet temperature is in the preset first temperature range, the running frequency of a compressor is controlledto be reduced, and accordingly the air return temperature is increased to be in the preset second temperature range. Accordingly, when the air conditioner runs in the automatic temperature rise mode,the indoor temperature can be accurately and effectively controlled to be reduced to be lower than the set temperature, and accordingly the requirements of users are met; and after maintaining is conducted for a period of time, the indoor temperature is accurately and effectively increased by a certain temperature, the cold feeling caused by the too low human body surface temperature is avoided, and the user experience degree is greatly improved.

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...

AI Technical Summary

Problems solved by technology

[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 automatic temperature recovery mode, the air conditioner cannot be accurately controlled, so that the user cannot be provided with timely and accurate comfort. For the problem of ambient temperature, when the air conditioner is running in refrigeration, it can accurately and effectively control the indoor temperature to drop below the set temperature to meet the needs of users, and after maintaining it for a period of time, it can accurately and effectively make the indoor temperature rise to a certain level Temperature, to avoid the cold feeling caused by the low surface temperature of the human body, thus greatly improving the user experience
