Air conditioner as well as control method and control device of air conditioner

Abstract

The invention provides an air conditioner as well as a control method and a control device of the air conditioner. The control method of the air conditioner comprises the steps that after a dehumidification starting signal is received, an indoor dry bulb temperature, indoor relative humidity and target relative humidity are obtained; an indoor environment dew point temperature is calculated according to an indoor environment temperature and the indoor environment relative humidity; a target dew point temperature is calculated according to the indoor environment temperature and the target relative humidity; an indoor unit target managing temperature is calculated according to the indoor environment dew point temperature; and dehumidification control is carried out on the air conditioner according to the indoor unit target managing temperature, so that the indoor environment dew point temperature and the target dew point temperature meet preset conditions. According to the method, intelligent dehumidification control can be realized, the dehumidification effect is improved, and the comfort of a user is met.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioner, a control method for the air conditioner and a control device for the air conditioner. Background technique [0002] With the development of science and technology and the improvement of people's living standards, people's requirements for the living environment are gradually increasing, especially the requirements for the humidity of the indoor environment are gradually increasing. [0003] The indoor unit of the existing air conditioner is usually only equipped with a conventional temperature sensor. The temperature sensor detects the indoor dry bulb temperature, and the air conditioner is controlled according to the detected dry bulb temperature. However, the dry bulb temperature cannot reflect the indoor humidity value. Therefore, the The air conditioner cannot meet the indoor humidity requirements very well, and the indoor temperature may be too ...

AI Technical Summary

Problems solved by technology

[0003] The indoor unit of the existing air conditioner is usually only equipped with a conventional temperature sensor. The temperature sensor detects the indoor dry bulb temperature, and the air conditioner is controlled according to the detected dry bulb temperature. However, the dry bulb temperature cannot reflect the indoor humidity value. Therefore, the The air conditioner cannot meet the indoor humidity requirements very well. It may cause the room to be too cold because the set temperature is too low, or the indoor dehumidification effect is poor because the set temperature is too high, which greatly affects the comfort of users.
