Abstract

The invention discloses an air conditioner and a method and a device for controlling the starting of a compressor of the air conditioner. The method for controlling the starting of the compressor of the air conditioner comprises the following steps of controlling the first compressor of a plurality of compressors of the air conditioner to start; starting timing when the first compressor is started, and obtaining the timing period; when the timing period reaches the preset time interval, obtaining the output power of the air conditioner; comparing the output power and the demand power of the air conditioner; when the output power is lower than the demand power, controlling the second compressor to start, wherein the second compressor is one of the multiple compressors and different from the first compressor. The method has the advantages that the problem of overlong starting time interval of the compressor in the prior art is solved, and the effects of shortening the starting time interval of the air conditioner and improving the energy modulation efficiency of the air conditioner are realized.

Description

technical field [0001] The present invention relates to the field of air conditioners, in particular to an air conditioner and a start-up control method and device for a compressor thereof. Background technique [0002] There are multiple compressors in the modular air conditioner, and the compressors need to be started sequentially during the start-up process. If the compressor starts too fast, it will easily cause fluctuations in the power supply voltage. The start-up time interval has the disadvantage of too long compressor start-up time interval. In the heating mode, the compressor start-up interval is too long, which may easily cause the heating power of the unit to be too low, so that the ambient temperature cannot quickly respond to the user's set value; in the cooling mode If the starting interval of the lower compressor is too long, it is also easy to cause the heating power of the unit to be too low, so that the ambient temperature cannot quickly respond to the use...
