Method and device for controlling temperature and humidity of air conditioner

Abstract

The invention discloses a method for controlling the temperature and humidity of an air conditioner. The method comprises the following steps that when the air conditioner conducts refrigerating, heating or dehumidifying, the indoor set temperature and the indoor set humidity of the air conditioner are obtained, and a target moisture content is obtained based on the indoor set temperature and the indoor set humidity; when it is detected that a current indoor environment temperature is equal to a preset comfortable temperature, a current moisture content of the indoor environment where the air conditioner is located is obtained; the difference value between the current moisture content and the target moisture content is calculated; and when the different value is less than or equal to a first preset value, the air conditioner is controlled to conduct dehumidifying. The invention further discloses a device for controlling temperature and humidity of the air conditioner. According to the method and device for controlling the temperature and humidity of the air conditioner, when the air conditioner is in the process of refrigerating, heating or dehumidifying, dehumidifying treatment is conducted to improve the humidity of the indoor environment when the humidity of the indoor environment is too low, so that the comfort degree when users use the air conditioner is further improved.

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
