Abstract

The invention provides a constant-frequency air conditioner and a control method and unit thereof. The control method includes: acquiring current indoor temperature and current outdoor temperature; comparing the current indoor temperature to set temperature of the constant-frequency air conditioner; and if the current indoor temperature is lower than or equal to the set temperature, adjusting flow of coolant of the constant-frequency air conditioner through electronic expansion valves according to the current outdoor temperature and the set temperature. The electronic expansion valves are disposed on connecting pipes directly used for gas returning of the compressor and arranged at two ends of a compressor of the constant-frequency air conditioner and are used for adjusting the flow of the coolant. The influence of shutdown at satisfied temperature upon fluctuation of room temperature and upon life of the compressor can be avoided, and comfortable functional auto-control is achieved for the constant-frequency air conditioner.

Description

technical field [0001] The invention relates to the technical field of air conditioning control, in particular to a control method of a fixed frequency air conditioner, a controller and the fixed frequency air conditioner. Background technique [0002] At present, almost all fixed-frequency air conditioners on the market control the temperature by turning off the temperature, that is, the air conditioner stops when the indoor ambient temperature reaches the set temperature of the remote control. [0003] However, the frequent temperature shutdown will greatly reduce the comfort of the room due to the fluctuation of the indoor ambient temperature and the discontinuity of the sound of the air conditioner. It will have a great impact on the life of the compressor. [0004] Therefore, it is of great significance to provide a control method, controller and fixed frequency air conditioner that can stably control room temperature without frequent shutdown.
