Control method of air conditioner

Abstract

The invention relates to the technical field of air conditioners, particularly to a control method of an air conditioner, and aims to solve the problem that a coil of an indoor unit is liable to ice and frost when a conventional air conditioner operates in a refrigeration mode when the outdoor environment temperature is relatively low. The control method of the air conditioner comprises the stepsof acquiring the operation mode of the air conditioner; when the operation mode is the refrigeration mode, acquiring the operation frequency of a compressor of the air conditioner and the outdoor environment temperature; and judging whether the air conditioner needs to enter the low-temperature refrigeration mode or not based on the operation frequency and the outdoor environment temperature. According to the control method, whether the air conditioner needs to enter the low-temperature refrigeration mode or not is judged based on the operation frequency of the compressor and the environment temperature in the refrigeration mode, the accuracy of judging whether the air conditioner needs to enter the low-temperature refrigeration mode or not can be improved, and the icing / frosting phenomenon of the indoor unit of the air conditioner is effectively reduced or avoided.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner control method. Background technique [0002] With the continuous advancement of science and technology, the application fields of air conditioners are also becoming wider and wider. Different from the traditional understanding that the air conditioner is used for cooling in summer and heating in winter, in some special application scenarios, the air conditioner may also need cooling operation in winter or when the temperature is low. Take the computer room air conditioner as an example. Since a large amount of heat generated by the electronic equipment in the computer room will affect the performance of the equipment, it is necessary to maintain a constant temperature and humidity indoor environment throughout the year in the computer room. Therefore, the computer room air conditioner usually maintains the cooling mode throughout the year. [0003] H...
