Control method and device of air conditioner and air conditioner with control device of air conditioner

Abstract

The invention discloses a control method and device of an air conditioner and an air conditioner with the control device of the air conditioner. The air conditioner runs in the refrigeration mode. Themethod comprises the following steps that a compressor in the air conditioner is identified to operate according to the lowest operation frequency; the first target operation frequency at the currentmoment of the compressor is acquired; a first body sensing temperature of a user at the current moment is acquired; according to the first target operation frequency and the first body sensing temperature, whether the air supply amount of the air conditioner needs to be reduced or not is judged; if it is judged that the air supply amount of the air conditioner needs to be reduced, the air supplyamount of the air conditioner is controlled to be reduced. Therefore, frequent starting and stopping of the compressor of a split air conditioner are avoided, energy resources are saved, the reliability of the compressor is improved, the indoor heat comfort is improved, and the technical problem that in the prior art, when the air conditioner operates at the lowest frequency, the output refrigerating capacity is larger than the indoor actual demand cold capacity 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 ...

Problems solved by technology

[0005] For this reason, the first object of the present invention is to propose a control method for an air conditioner, which avoids the frequent start and stop of the compressor of the split air conditioner, saves energy, improves the reliability of the compressor, and improves the thermal comfort of the room , 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
