Air conditioner

Abstract

The invention discloses an air conditioner, which is characterized by the following: assembling m air conditioner compressor with different refrigerating capacity; ranging capacity (Kw)number of each compressor to one sequence from small to big; setting the capacity number of the first compressor at 20a+ax1; setting the capacity of the second compressor at 21a+ax2; setting the capacity of the third compressor at 22a+ax3......; setting the capacity of the m compressor at 2m-1a+axm; setting the a as constant at will X1, X2, X3......; setting the Xm as actual number between (0+-0.25); arranging separate drive motor at each compressor; setting optimization number of the compressor between 2 and 10; choosing and combining each compressor for each driving and stopping according to the change of load; getting more capacity adjustable grade number of the air conditioner.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to the capacity adjustment technology of multiple compressors of the air conditioner. Background technique [0002] Each compressor of the existing air conditioner equipped with multiple compressors has an independent drive motor, and the capacity of the air conditioner is adjusted by changing the number of compressor motors that are turned on and off, which belongs to the step capacity adjustment, as described in the patent (Application No. 98228481.0), patent (Application No. 00239843.5), most air conditioners are equipped with multiple compressors with the same capacity, and its disadvantage is that the number of compressors required is less than the number of capacity adjustment stages that can be achieved; a few air conditioners The capacity of multiple compressors selected by the machine is different. The disadvantage is that because there is no proper des...

[0002] Each compressor of the existing air conditioner equipped with multiple compressors has an independent drive motor, and the capacity of the air conditioner is adjusted by changing the number of compressor motors that are turned on and off, which belongs to the step capacity adjustment, as described in the patent (Application No. 98228481.0), patent (Application No. 00239843.5), most air conditioners are equipped with multiple compressors with the same capacity, and its disadvantage is that the number of compressors required is less than the number of capacity adjustment stages that can be achieved; a few air conditioners The capacity of multiple compressors selected by the machine is different. The disadvantage is that because there is no proper design and matching method, it is impossible to ensure that the multiple compressors selected can reach the maximum number of capacity adjustment stages corresponding to the number of sets. At the same time, the capacity adjustment between each stage The value fluctuates greatly
