Abstract

The invention discloses a compressor energy control circuit and method and a centrifugal water chilling unit. The compressor energy control circuit comprises a rectifying circuit and a charging loop. The rectifying circuit comprises a direct-current side and an alternating-current side. The alternating-current side of the rectifying circuit is connected with a motor of a compressor to convert the alternating current generated by motor reverse rotation into direct current and output the direct current through the direct-current side of the rectifying circuit. The charging loop is connected with the direct-current side of the rectifying circuit to store the direct current output by the direct-current side of the rectifying circuit. By means of the compressor energy control circuit and method and the centrifugal water chilling unit, the effect that waste of energy in an air conditioner is reduced is achieved.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a compressor energy control circuit and control method and a centrifugal chiller. Background technique [0002] Generally, all the electrical components in the air conditioner need to be powered by the mains, such as the loads such as compressors and fans in the air conditioner, and these electrical components are powered by the mains grid, resulting in the There is a lot of power. The inventors have found that the compressor in the air conditioner is stopped slowly by inertia, and all the energy in the compressor shutdown process is lost, resulting in a waste of energy. [0003] Aiming at the problem of energy waste in air conditioners in the prior art, no effective solution has been proposed yet. Contents of the invention [0004] The main purpose of the present invention is to provide a compressor energy control circuit and control method and a centrifugal chiller to solve ...
