Problems solved by technology

However, when four compressors are running at the same time, the total amount of instantaneous overcurrent generated on each compressor will exceed the capacity of the power supply components supplying power to these four compressors, thus overloading and overheating the power supply components, causing them to be damaged. damage

Abstract

Disclosed is a method for operating a plurality of compressors of an air conditioner in accordance with a cooling or heating load in a room, in which a power supply unit for supplying power to the compressors is protected when a cooling or heating load in a room is the highest grade. The method comprises the steps of: (a) determining the cooling or heating load in the room; and (b) sequentially operating the plural compressors when it is determined as a result of the step (a) that the cooling or heating load in the room is in the highest grade.

Description

technical field [0001] The present invention relates to an air conditioner comprising a plurality of compressors, and in particular to a method of controlling the operation of the compressors of the air conditioner, the method comprising: when the cooling or heating load in the room is at the highest level, making the plurality of compressors The machines run sequentially. Background technique [0002] Generally speaking, an air conditioner is a device that uses a refrigerant compressed by a compressor to perform a refrigeration cycle to cool or heat a room. [0003] The compressor includes a compression unit with a compression chamber for compressing refrigerant and a motor unit for changing the capacity of the compression chamber. In line with the trend of large-scale and multi-functional development, air conditioners including two compressors or one inverter-type compressor have been developed so that the total operating capacity of the compressors can be adjusted accord...
