Embodiment Construction

[0022] Reference will now be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings.

[0023] Below, refer to image 3 , will explain a method for controlling an air conditioner with multiple compressors by storing the compression capacity of the compressor in advance according to the difference between the previous room temperature and the desired temperature predetermined by the user, and by The pre-stored compression capacity can be changed by using the temperature difference between the temperatures, the method can enhance the corresponding ability to the cooling load or the heating load, and reduce the energy loss.

[0024] image 3 is a flowchart of a method for controlling an air conditioner with multiple compressors according to a preferred embodiment of the present invention.

[0025] As shown in the figure, a method for controlling an air conditioner with multiple compressors according to a prefe...

Abstract

The present invention discloses a method for controlling an air conditioner having multiple compressors, which can improve performance corresponding to room cooling load or room heating load, and can reduce energy loss of the air conditioner. For this purpose, the compression capacity is stored in advance according to the temperature difference between the previous room temperature and the desired temperature predetermined by the user. Then, the pre-stored compression capacity is changed according to the temperature difference between the current room temperature and the desired temperature.

Description

technical field [0001] The invention relates to an air conditioner, in particular to a method for controlling an air conditioner with multiple compressors. Background technique [0002] Generally, an air conditioner is used to cool indoor hot air or to heat indoor cold air. will refer to figure 1 An air conditioner having two compressors according to the conventional art will be described. The two compressors are selectively operated according to the room cooling load. [0003] figure 1 is a schematic diagram showing the structure of an air conditioner having two compressors according to the conventional art. [0004] As shown, the air conditioner with two compressors includes: a first compressor 18A and a second compressor 18B, which are selectively operated by the room cooling load for varying the compression capacity; a condenser 1 for discharging The heat of the refrigerant compressed by the first and second compressors 18A and 18B; the expansion valve 2 for expandi...
