Embodiment approach

[0043] Because air-conditioning systems are very common, the same parts as existing air-conditioning technologies, such as fans, solenoid valves, and other conventional components, as well as some conventional control circuits and control methods, will not be introduced here. The difference in technology.

[0044] Such as figure 1 As shown, figure 1 It is a schematic diagram of the first embodiment of the air conditioning system of the present invention. The air conditioning system of the present invention includes a compressor 1, an outdoor heat exchanger 2, an expansion valve 3, an indoor heat exchanger 5, and the indoor heat exchanger 5 consists of three sets of heat exchangers: a first heat exchanger 5a, a second heat exchanger The second heat exchanger 5b and the third heat exchanger 5c are formed in parallel. The advantage of such an indoor heat exchanger is that the heat exchange efficiency of the indoor heat exchanger can be fully utilized and the energy efficiency ratio ...

Abstract

The invention provides an air conditioning system and a flow control method thereof, and an electric flow distributor for implementing the flow control method. A flow control system of the air conditioning system in the prior art has the defects of high fault rate due to more parts and components and complex pipeline connection, and the like. In the air conditioning system of the invention, a flow distributing system with the electric flow distributor is arranged between an expansion valve and indoor heat exchangers to distribute the flow of a refrigerant to each indoor heat exchanger or eachgroup of heat exchangers of the indoor heat exchanger so as to complete the flow distribution of indoor units of a one-driving-more air conditioning system or the flow distribution of the air conditioning system comprising a plurality of groups of heat exchangers; and the air conditioning system automatically regulates the opening degree of the expansion valve and the flow of the refrigerant, uniformly distributes the flow among all the indoor units or all the groups of heat exchangers, fully develops the heat exchange function of all the indoor units or all the groups of heat exchangers and reduces the waste of heat exchange areas so as to improve the efficiency of the whole air conditioning system.

Description

Technical field [0001] The invention belongs to an air conditioning system, in particular to a flow control method of the air conditioning system, and an electric flow distributor for realizing the flow control method. Background technique [0002] Most of the air-conditioning systems in the prior art include indoor heat exchangers, outdoor heat exchangers, compressors and throttling devices. In some air-conditioning systems with one-to-many systems, in order to improve the heat exchange efficiency of the heat exchanger, the internal refrigerant The distribution of flow rate has always been a technical difficulty; many systems use electronic expansion valves to individually control and distribute the flow rate of each indoor unit, as disclosed in the publication specification of the invention patent application No. 200610145015.2 filed on November 29, 2006 In the solution, each indoor unit is used to intelligently adjust the electronic expansion valve of each indoor unit through ...
