Electric throttling distribution mechanism, air conditioner system and flow control method thereof

Abstract

The invention relates to an electric throttling distribution mechanism which comprises a casing, an input connecting pipe, 2 outlet connecting pipes and at least 1 throttling hole, wherein the throttling hole is respectively communicated with each outlet connecting pipe; a coil component is fixed on the exterior of the casing; the interior of the casing is provided with a valve cavity, and the valve cavity is communicated with the input connecting pipe; an attracting piece is fixed at one end of the valve cavity; the interior of the valve cavity is also provided with a movable iron core and a return spring, wherein the movable iron core can move in a reciprocating way and the return spring is arranged between the attracting piece and the movable iron core; and the electric throttling distribution mechanism realizes the flow distribution between at least two throttling holes through the reciprocating movement of the movable iron core, realizes the flow throttling and distribution of the refrigerant to 2 groups of heat-exchanging units or 2 groups of heat exchangers, and then completes the flow throttling and distribution in the indoor machine in the one-for-two air conditioner system or the flow energy saving and distribution of the refrigerating system comprising 2 groups of heat exchangers; the flow distribution between the heat-exchanging units or groups of heat exchangers is uniform, therefore the heat exchange function can be fully performed; and the waste of heat exchange area is reduced, therefore the efficiency of the system is improved.

Description

technical field [0001] The invention belongs to an electric throttling distribution mechanism, in particular to an electric throttling distribution mechanism for an air-conditioning system. 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 through distributors and expansion valves, such as the invention patent application number 200610145015.2 filed on November 29, 2006 The solution disclosed in the application publication specification uses 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 drag multiple air conditioners . Another example is t...
