Abstract
The invention discloses a structure with double thermostatic expansion valves, and relates to the technical field of air conditioner refrigeration. The structure comprises two thermostatic expansion valves of the same models. The structure is characterized in that the thermostatic expansion valves are in parallel connection respectively through copper pipes which are equal in length and tortuosity, a flow-splitting tee joint is arranged at the positions of inlets which are in parallel connection, a flow-combining tee joint is arranged at the positions of outlets which are in parallel connection, and a balance pipe is connected between the two thermostatic expansion valves. Compared with the prior art, the structure with the double thermostatic expansion valves can control cost, and at the same time, satisfies the demand of large refrigeration capacity of a machine set.
Description
Technical field
The present invention relates to the air conditioner refrigerating technical field, particularly two thermal expansion valve arrangements.
Background technology
Water-cooled handpiece Water Chilling Units of the prior art comprises that the water source heat pump units majority that switch in the water route is to adopt single expansion valve mechanism, i.e. the corresponding expansion valve of a compressor.The expansion valve that needs to mate when compressor is larger also should be larger, the high expensive though the electric expansion valve range of operation can meet the demands.And the refrigerating capacity that most of single heating power expansion valves can provide is less than normal, and large heating power expansion valve optional model is few and price is high.For factory, due on address many-sided reason such as the supply of material, make the certain model compressor possibly can't select the liquid supply rate that suitable single heating power expansion valve satisfies evaporimeter.
Summary of the invention
Deficiency for above-mentioned prior art exists the purpose of this invention is to provide a kind of pair of thermal expansion valve arrangement.It can satisfy unit to the demand of larger refrigerating capacity when controlling cost.
In order to reach the foregoing invention purpose, technical scheme of the present invention realizes as follows:
A kind of pair of thermal expansion valve arrangement, it comprises the heating power expansion valve of two same model.Its design feature is, described each heating power expansion valve is connected in parallel by the copper pipe of equal length and flexibility respectively, and the porch that is connected in parallel is equipped with diversion three-way, and the exit that is connected in parallel is equipped with the interflow threeway, connects balance pipe between two heating power expansion valves.
In above-mentioned pair of thermal expansion valve arrangement, minute stream interface of described diversion three-way is identical with the import bore of heating power expansion valve, and the interflow interface of interflow threeway is identical with the outlet bore of heating power expansion valve.
The present invention satisfies unit to the demand of larger refrigerating capacity owing to having adopted said structure with two heating power expansion valves that are connected in parallel.When controlling cost, had range of application widely.
The invention will be further described below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
Referring to Fig. 1, the present invention includes the heating power expansion valve 2 of two same model, each heating power expansion valve 2 is connected in parallel by the copper pipe 5 of equal length and flexibility respectively.The porch that is connected in parallel is equipped with diversion three-way 1, and the exit that is connected in parallel is equipped with between 4, two heating power expansion valves 2 of interflow threeway and connects balance pipe 3.Minute stream interface of diversion three-way 1 is identical with the import bore of heating power expansion valve 2, and the interflow interface of interflow threeway 4 is identical with the outlet bore of heating power expansion valve 2.
When the present invention uses, cold-producing medium is flowed through other assembly (as device for drying and filtering, magnetic valve etc.) that the liquid pipe connects afterwards through diversion three-way 1 shunting, two heating power expansion valves 2 of flowing through respectively, then enter evaporimeter carry out normal kind of refrigeration cycle after interflow threeway 4 is confluxed.
In structure of the present invention, if the model of two heating power expansion valves 2 is different, may cause the aperture of two valves different, cause certain valve open degree too little, not play due throttling action.The combination of pipeline in the present invention is identical, can avoid two paths resistances different and affect the aperture of expansion valve.
Claims (2)
