Problems solved by technology

Due to the limitation of the structure of the compressor body, the existing compressors generally only have two gears for adjusting the working volume in terms of ease of control and manufacture.
This kind of compressor still cannot meet the demand of cooling capacity adjustment in the actual use process

Embodiment Construction

[0034] The present invention will be described in detail below. In the following paragraphs, different aspects of the embodiments are defined in more detail. Aspects so defined may be combined with any other aspect or aspects unless specifically stated otherwise. In particular, any feature considered to be preferred or advantageous may be combined with one or more other features which are considered to be preferred or advantageous.

[0035] Terms such as "first" and "second" appearing in the present invention are only for convenience of description, to distinguish different components with the same name, and do not indicate a sequence or a primary and secondary relationship.

[0036] For traditional variable capacity compressors, one is to use equal-capacity cylinders from the perspective of ease of manufacture and control. When the total capacity of equal-capacity cylinders is fixed, only two gears can be adjusted, and the minimum working volume is limited. When the air-con...

Abstract

The present disclosure relates to an air conditioning system and a control method therefor. The air conditioning system comprises: an indoor unit; a compressor, provided with a plurality of independent cylinders therein, at least two of the plurality of cylinders having different working volumes; and a control unit, configured to determine whether to operate each of the cylinders according to the load requirement of the current indoor unit. The air conditioning system enables a compressor to have more output levels when adjusting the volume so as to better satisfy the volume adjustment requirement of an indoor unit when in use, thereby improving the performance and efficiency of the air conditioning system when under a low load, reducing energy consumption.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioning system and a control method thereof. Background technique [0002] According to the statistics, most of the users only turn on one internal unit for the current multi-connected units on the market. In order to meet the needs of multiple indoor units working at the same time, the minimum output of the compressor itself is relatively large, which makes the multi-connected units Inefficient at low loads, very power hungry in normal use. [0003] In order to solve this problem, a compressor capable of variable frequency and variable capacity is used in the air conditioning system at present, and variable capacity technology is added on the basis of the variable frequency compressor to broaden the output range of the compressor. Due to the limitation of the structure of the compressor body, the existing compressors generally only have two gears for adjust...
