Embodiment Construction

[0053] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0054] The principle of the present invention will be described in detail below in conjunction with the embodiments.

[0055] The control method proposed by the present invention is suitable for air-conditioning systems. The multi-connected air-conditioning unit includes a control module, an outdoor unit, and a plurality of indoor units connected to the outdoor unit. The outdoor unit has more than two inverter compressors, and the indoor unit includes an air-conditioner , The indoor unit of the air conditioner generally refers to the fan coil unit, which is used to...

Abstract

The invention discloses a control method of an air conditioning system, the air conditioning system and an air conditioner. Judging whether the number of started compressors needs to be adjusted according to the running state of the air-conditioning system; when the number of the started compressors needs to be reduced, at least one started compressor is selected to be closed, and the frequency increasing action is executed on all the adjusted started compressors; and / or when the number of the started compressors needs to be increased, at least one closed compressor is selected to be started, and the frequency reduction action is executed on all the adjusted started compressors. By adjusting the starting number of the compressors and the operation frequency of the started compressors, the indoor load requirement is met, and energy-saving operation is kept.

Description

technical field [0001] The invention relates to the technical field of air conditioning control, in particular to a control method of an air conditioning system, an air conditioning system and an air conditioner. Background technique [0002] With the gradual intensification of global warming, the role of air conditioners in human life is becoming more and more important, and there are more and more application scenarios for air conditioners, especially multi-system inverter air conditioners are becoming more and more popular. The existing multi-system inverter air conditioner is a refrigeration cycle system composed of an outdoor unit connected to several indoor units. The outdoor unit has more than two compressors, and the compressors use inverter compressors. The frequency of each compressor is adjusted independently during the operation process, resulting in excessive frequency difference of compressors, uneven cooling rate, which does not meet the requirements of high-e...
