Problems solved by technology

[0020] It can be seen from the above that the existing methods for optimizing multi-connected air-conditioning systems usually only consider whether the rated output of the system meets the required output demand threshold, and do not consider the energy efficiency ratio of the system, so that the system meets the required output demand threshold. When the energy consumption (power consumption) may be large, the energy efficiency is relatively low; further, this method also leads to uneven distribution of the output of each compressor in the multi-connected air-conditioning system, and some compressors are shut down for a long time, while Other compressors have been on for a long time, which affects their service life

Embodiment Construction

[0098] The technical solutions of the various embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0099] As the country pays more and more attention to energy saving and emission reduction, users are also paying more and more attention to the energy efficiency ratio index reflecting the comprehensive performance of the multi-connected air-conditioning system, that is, the ratio between the output and input power of the multi-connected air-conditioning system under rated working conditions and specified conditions. The larger the energy efficiency ratio, the more energy-efficient ...

Abstract

The application discloses a method for controlling the operation of the compressors in an optimized VRV air conditioning system and a device thereof. The device includes the following steps: obtaining the rated output information and the rated power consumption information of the compressor in the VRV air conditioning system; obtaining the required output demand threshold value; and selecting the compressors and the operating frequencies, so that the total of the rated output of the selected compressors is no less than the output demand threshold value and the total of the rated power consumption of the selected compressors is the minimum. By utilizing the application, the actual operation energy efficiency ratio of the optimized VRV air conditioning system can be improved.

Description

technical field [0001] The invention relates to air-conditioning intelligent energy-saving technology, in particular to a method and device for optimizing the operation control of compressors in a multi-connected air-conditioning system.
