Abstract

The invention belongs to an electrical flow distribution mechanism for a refrigerating system, in particular to an electrical flow distribution mechanism for a multi-split air conditioner system or a refrigerating system with a plurality of groups of heat exchangers. The electrical flow distribution mechanism comprises an outer casing, a valve body, an inlet, an inlet connecting pipe, a pluralityof outlets, outlet connecting pipes and a step motor for driving, wherein the inlet connecting pipe is communicated with the inlet; and the outlet connecting pipes are communicated with the outlets. A valve cavity is formed between the valve body and the outer casing. The inlet is communicated with the valve cavity. The outlets are respectively arranged in the circumferential position of the valve body. The flow distribution among the outlets is realized by the step motor driving a shaft to rotate. After the structure is used, the invention has the advantages of small contour, low height, simple structure and low power consumption.

Description

technical field [0001] The invention belongs to an electric flow distribution mechanism for a refrigeration system, in particular to an electric flow distribution mechanism used in a one-to-many air-conditioning system or a refrigeration system with multiple sets of heat exchangers. Background technique [0002] Most air-conditioning systems in the prior art include indoor heat exchangers, outdoor heat exchangers, compressors, and throttling devices. The flow distribution has always been a technical difficulty; many systems use electronic expansion valves to individually control each indoor unit and distribute the flow, as disclosed in the publication of the invention patent application number 200610145015.2 filed on November 29, 2006 The solution is to use a control valve module for each indoor unit to intelligently adjust the electronic expansion valve of each indoor unit, so as to realize the on-demand distribution of the refrigerant flow of one-to-many air conditioners. ...
