Problems solved by technology

[0005] For this reason, the first object of the present invention is to propose a control method for air conditioners, which avoids the frequent start and stop of compressors in an air conditioner system in which multiple compressors are connected in parallel, saves energy, improves the reliability of the compressors, and improves the indoor temperature. Excellent thermal comfort, which solves the technical problem in the prior art that the output cooling capacity of the air conditioner is greater than the actual indoor cooling capacity when the air conditioner operates at the lowest frequency

Abstract

The invention discloses a control method and a control device for an air conditioner and the air conditioner provided with the same. The air conditioner operates in a command mode. The method comprises the following steps: identifying that compressors in the air conditioner operate at the lowest operating frequency; and controlling to increase the opening of an electronic expansion valve in the air conditioner to a target opening. Therefore, the condition that the compressors of an air conditioning system where the plurality of compressors are connected in series are started and stopped frequency is avoided, the energy sources are saved, the reliability of the compressors is improved, the indoor thermal comfort is improved, and the technical problem that in the prior art, the output refrigerating capacity is greater than the indoor actually demanded refrigerating capacity when the air conditioner operates at the lowest frequency is solved.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to an air conditioner control method and device and an air conditioner 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 before the ...
