Abstract

The invention discloses a control method and device for an air conditioner. The air conditioner comprises an outdoor unit, an indoor unit and N branch circuits connected in parallel, wherein N is an integer greater than one, and the outdoor unit is connected with the indoor unit through the N branch circuits connected in parallel. The air conditioner runs in a refrigeration mode. The method comprises the following steps of recognizing that an air conditioner compressor runs according to the smallest running frequency; obtaining target running frequency of the air conditioner; and if the targetrunning frequency is smaller than a first preset value, controlling more branch circuits of the N branch circuits connected in parallel to be switched on. By means of the control method and device for the air conditioner, the technical problem that when an air conditioner runs according to the smallest frequency, output refrigeration capacity is greater than actual indoor required refrigeration capacity in the prior art is effectively solved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner control method and device. Background technique [0002] In the related art, the operation mode of the inverter air conditioner is as follows: at the beginning, the compressor is controlled to run at high frequency, and the indoor temperature drops rapidly. (The preset value is 1°C~5°C, depending on the setting of each manufacturer), the air conditioner will reach the temperature and stop, that is, the compressor will stop running. As time goes by, when the indoor temperature rises to the condition for automatic start, the air conditioner will restart open. As the difference between the indoor temperature and the preset temperature decreases, the operating frequency of the compressor will also decrease. Finally, in the stage before the shutdown, the compressor will run at the minimum frequency that can be operated, so that the air conditioner can cool...
