Method and device for controlling temperature and humidity of air conditioner

Abstract

The invention discloses a temperature and humidity control method of an air conditioner, which comprises: when the air conditioner is cooling, heating or dehumidifying, obtaining a target moisture content based on the indoor set temperature and indoor set humidity; When the preset comfortable temperature is reached, the current moisture content is obtained based on the current indoor ambient temperature and the current indoor air humidity; the difference between the current moisture content and the target moisture content is calculated; when the difference is less than or equal to the first preset value , the air conditioner is controlled to perform humidification processing, and when the difference is greater than the second preset value, and the air conditioner is cooled or dehumidified according to the automatic wind speed, the air conditioner is controlled to perform dehumidification processing. The invention also discloses a temperature and humidity control device of the air conditioner. The invention realizes the humidification process when the humidity of the indoor environment is too low during the cooling, heating or dehumidification process of the air conditioner, or performs the dehumidification process when the humidity of the indoor environment is too high, thereby improving the efficiency of the user when using the air conditioner. of comfort.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a temperature and humidity control method and device for an air conditioner. Background technique [0002] At present, air conditioning usually includes three aspects of regulation, namely temperature, humidity and cleanliness. In recent years, people have paid more and more attention to air cleanliness, but the emphasis on humidity has not changed much. [0003] People often use air conditioners to adjust the temperature of the indoor environment, and do not pay attention to the humidity of the indoor air. However, when the user uses the air conditioner to adjust the temperature of the indoor environment, it is difficult to adjust the humidity of the indoor air to an appropriate range, which causes the user to feel uncomfortable. For example, in the process of using air conditioners for heating in autumn and winter, because the air in autumn and winter is relatively d...

Problems solved by technology

However, when the user uses the air conditioner to adjust the temperature of the indoor environment, it is difficult to adjust the humidity of the indoor air to an appropriate range, causing the user to feel uncomfortable.

For example, in the process of using air conditioners for heating in autumn and winter, because the air in autumn and winter is relatively dry and the water content in the air is low, as the room temperature continues to rise, it will cause high temperature and low humidity in the room, causing users to feel uncomfortable; In the high-temperature and high-humidity environment in the southern summer, when the air conditioner is used for cooling, before the room temperature reaches the set temperature and when the room load is large, the air conditioner needs a large cooling capacity to cool down and maintain the load, so it keeps working at a high level. Frequency operation, resulting in excessive dehumidification during the cooling process, resulting in low temperature and low humidity in the room, causing users to feel uncomfortable; or, in the high temperature and high humidity environment in the southern summer, when the air conditioner is used for cooling, when the room load is small, the air conditioner maintains The cooling capacity required by the load is small, so the air conditioner keeps running at a low operating frequency, causing the air conditioner to keep cooling but not dehumidifying, resulting in low temperature and high humidity in the room, causing users to feel stuffy
