Control method for controlling operation of air conditioner and air conditioner

Abstract

The invention relates to a method for controlling operation of an air conditioner and the air conditioner. According to one aspect of the invention, the method for controlling operation of the air conditioner (AC) is provided. The air conditioner comprises an indoor unit (10). The indoor unit is provided with a first air outlet (20) and a second air outlet (30). The air conditioner further comprises a compressor (80) and an expansion valve (84) which constitute one part of an air conditioner circulation loop. The control method comprises the following control steps that during operation of the air conditioner, when either of the first air outlet and the second air outlet is closed or either of the opening degree of the first air outlet and the opening degree of the second air outlet is reduced, operation of the compressor and / or operation of the expansion valve are / is adjusted according to the operation mode of the air conditioner, the environmental temperature and / or operating parameters of the air conditioner. According to the method for controlling operation of the air conditioner and the air conditioner, an air conditioner system can be effectively controlled, system fluctuation of a whole machine can be optimized, and the problem of reliability of the air conditioner can be solved.

Description

Technical field [0001] The present invention relates to the field of air conditioning, and in particular to a control method for controlling the operation of an air conditioner capable of optimizing the operation of an air conditioning system and an associated air conditioner. Background technique [0002] At present, the indoor unit of the air conditioner (especially the indoor unit of the cabinet type air conditioner) may be provided with two air outlets, such as an upper air outlet and a lower air outlet. The upper and lower air outlets can be opened, closed or adjusted independently of each other through respective air door switch devices. During the normal operation of the air conditioner, when one of the upper and lower air outlets is closed or the opening is reduced (for example, the lower air outlet is closed in the cooling mode to prevent the cold wind from blowing directly to the human body), the air volume of the whole machine will change Affected, which in turn will ...

AI Technical Summary

Problems solved by technology

During the normal operation of the air conditioner, when one of the upper and lower air outlets is closed or its opening is reduced (for example, the lower air outlet is closed in cooling mode to avoid cold air blowing directly to the human body), the air volume of the whole machine will decrease. affected, which will have a greater impact on the operation stability of the air conditioner system
