Abstract

The invention relates to an air conditioner and a control method thereof. The control method comprises the following steps that the indoor environment temperature and the indoor environment relative humidity of a space where an air conditioner indoor unit of the air conditioner is located are detected under a refrigeration operation mode; the air dew point temperature of the indoor environment iscalculated according to the indoor environment temperature and the indoor environment relative humidity; the target coil temperature of the air conditioner is determined according to the interval where the indoor environment temperature and the indoor environment relative humidity are located and the calculated air dew point temperature; and the operation frequency of a compressor of the air conditioner is determined through coil temperature PID control. According to the air conditioner and the control method thereof, the temperature of the indoor coil is accurately controlled according to theindoor temperature and humidity, in the whole refrigeration operation process, the indoor temperature and humidity are simultaneously controlled, the operation mode of the air conditioner is not required to be adjusted by an user according to the indoor environment, or, the set temperature deviating the intention of the user is not required to be set, and the intelligence degree of the air conditioner and the use experience of the user are improved.

Description

technical field [0001] The invention relates to an air conditioner, in particular to an air conditioner control method and the air conditioner. Background technique [0002] At present, during the refrigeration or dehumidification process of air conditioners, the evaporation temperature is not directly and accurately controlled, and there are often large fluctuations during operation. Under high temperature and high humidity conditions, the evaporation temperature is often higher than the air dew point temperature, resulting in low dehumidification efficiency and slow humidity drop. Under low-temperature and low-humidity conditions, the evaporation temperature is often lower than the air dew point temperature, resulting in too low air outlet temperature, giving users a bad experience of being too cold, and the dehumidification effect is better, the air is getting drier, and energy is wasted. [0003] For high-temperature and high-humidity working conditions, the existing co...
