Embodiment Construction

[0029] Now, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0030] The heat pump air conditioning system using the compressor has been referred to figure 1 be described. image 3 is a block diagram of an air conditioning system with two compressors according to the invention. exist image 3 In , the solid line arrows indicate the flow of control signals from the control unit to each component of the air conditioner, while the dotted line arrows indicate the flow of refrigerant between the various components of the air conditioner. refer to image 3 , the air conditioning system with two compressors of the present invention is described as follows:

[0031] The compressor 100 sucks gaseous refrigerant evaporated by the evaporator, and then compresses the sucked gaseous refrigerant to transform it into a high-pressure state. As a result, the molecular kinetic energy within the gaseous refrigerant incr...

Abstract

Disclosed are an air conditioning system with two compressors and a method for operating the same, so as to variably change a compression capacity of a refrigerant according to the variation of cooling load. Herein, when a full operation order is inputted to the two compressors in order to satisfy increased cooling load, the first compressor is first operated, and then the second compressor having a compression capacity of a refrigerant smaller than that of the first compressor is additionally operated, so that a current peak value for operating the compressors does not exceed an allowable current range of a circuit breaker installed in a home or building, thereby safely controlling the air conditioning system and simultaneously allowing the current to be provided to other electric appliances, thus improving users' convenience.

Description

technical field [0001] The present invention relates to an air conditioning system with two compressors and its operating method, and more particularly to an air conditioning system with two compressors and its operating method, wherein when the first compressor operates first Then, when the second compressor works sequentially, the current value required to operate the compressor will not exceed the allowable current range of the circuit breaker installed in the home, thereby safely controlling the air-conditioning system and other household electrical appliances. Background technique [0002] figure 1 is a block diagram illustrating the flow of refrigerant in a conventional air conditioning system, while figure 2 is a graph showing current variation in a conventional air conditioning system. refer to figure 1 and 2 , the traditional air conditioning system is described as follows: [0003] Generally, a conventional air conditioner realizes the refrigeration function ...
