Air conditioner control method and device and air conditioner unit with air conditioner control device

Abstract

The invention discloses an air conditioner control method and device and an air conditioner unit with the air conditioner control device. An air conditioner is operated in a refrigeration mode. The method comprises the steps that a compressor in the air conditioner is recognized to be operated at the lowest operation frequency; the temperature difference between the current indoor environment andthe set temperature of the air conditioner is obtained; and the temperature difference is compared with a preset first threshold value, and if the temperature difference is smaller than or equal to the first threshold value, the air conditioner is controlled to reduce output of the refrigerating capacity. Accordingly, the compressor is prevented from being frequently started and stopped, energy issaved, reliability of the compressor is improved, indoor heat comfort is improved, and the technical problem that the output refrigerating capacity of the air conditioner operated at the lowest frequency is larger than the indoor practically-required refrigerating capacity in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to an air-conditioning control method and device and an air-conditioning unit having the same. Background technique [0002] At present, the control method of the conventional inverter air conditioner is that the compressor runs at high frequency after starting up, and the indoor temperature drops rapidly. ℃~5℃, according to the setting of each manufacturer), the air conditioner will reach the temperature and stop. After shutting down, the indoor temperature will no longer drop due to the influence of the air conditioner. As time goes by, when the indoor temperature rises to the condition of automatic startup, the air conditioner will be turned on again. As the difference between the indoor temperature and the temperature set by the remote control decreases, the operating frequency of the compressor will also decrease. Finally, the compressor will run at the lowest power befo...
