Abstract
The utility model relates to a refrigerating and air-conditioning device using a multistage expansion assembly. The multistage expansion assembly is composed of two or more capillary pipes with different inner diameters in series connection in a single stage miniature refrigerating and air-conditioning device. The multistage expansion assembly is composed of two or more expansion valves in series connection in a single stage large refrigerating and air-conditioning device.
Description
The utility model relates to the technical field of refrigeration and aircondition, what specially refer to is the expansion assembly part of these devices.
As everyone knows, in all refrigeration, aircondition, expansion system is arranged all.In large-scale refrigeration, aircondition, often use expansion valve or decompressor.In small-sized refrigerating, aircondition, often use capillary.In single-stage small-sized refrigerating or aircondition, all use the capillary of a certain diameter, once expand into the end, in large-scale single-stage refrigeration and aircondition, often also only use one time expansion process.Common expansion assembly is, or once expand into the end with an expansion valve, or with two or three expansion valve parallel connections, thereby also be once to expand into the end.Referring to " Refrigeration ﹠ Air-Conditioning Hardware Description Manual "＜International Industry publishing house, 1987 〉.
The defective of existing this cover expansion assembly is that an a kind of expansion assembly of very difficult selection can make refrigeration and aircondition, reaches optimal state.For example, an existing refrigerating plant＜referring to Fig. 1 〉, pipe among the figure between A, the B is the capillary expansion assembly, suppose that it is that 1.73 millimeters, length are 0.8 meter capillary that this refrigeration system needs internal diameter, and there is not the capillary of this specification on the market, then can only replace with close capillary, as being that 1.9 millimeters capillary replaces with internal diameter, then can only adjust its length, so that its effect is that 1.73 millimeters, length are 0.8 meter capillary near internal diameter as best one can, ordinary circumstance can not reach very approaching result, usually can not be satisfactory.
Therefore, be necessary to look for a kind of new expansion assembly, it always can adjust to whole refrigeration and aircondition is optimum state.
The design people is through research for a long time, finally designed a kind of multiple stage expansion assembly, this assembly promptly is, in a single-stage small-sized refrigerating, air-conditioning system, the capillary that adopts two or two above different-diameters is connected in series and the expansion assembly＜structure is referring to Fig. 2 and Fig. 3〉made.In the large-scale refrigeration of a single-stage, air-conditioning system, adopt two or more expansion valves expansion assembly＜series system is referring to Fig. 4〉that is in series.These two kinds of expansion assemblies are exactly content of the present invention.Up to the present, yet there are no, in single-stage small-sized refrigerating, aircondition, the capillary of useful two or more diameter series connection and use as expansion gear.In the large-scale refrigeration of single-stage, aircondition, do not see what two expansion valve series connection of handlebar were used yet.
These two kinds designed novel expansion system biggest advantage of the design people are, always can be by independently the adjusting a wage scale of the expansion components at different levels in the multiple stage expansion assembly, thus make refrigeration, aircondition on thermodynamics, reach the result of optimization.Be that example illustrates this advantage still below with the single-stage Small Refrigerating Equipment of Fig. 1.
Because it is that 1.73 millimeters, length are 0.8 meter capillary that the refrigerating plant among Fig. 1 needs internal diameter, and there is not the capillary of this specification on the market, then available internal diameter is that 2.2 millimeters, length are that x rice and internal diameter are 1.9 millimeters, length is that the capillary of y rice is connected in series＜such as welding, referring to Fig. 2 and shown in Figure 3 〉, adjust the value of length x and y, then can find one group of x, y value, making expansion effect after its series connection be equivalent to internal diameter is that 1.73 millimeters, length are 0.8 meter expansion effect capillaceous.Equally also can be respectively be that 2.2 millimeters, length are x rice with internal diameter, internal diameter is that 2.0 millimeters, length are y rice, internal diameter is that 1.9 millimeters, length are that three sections capillaries of z rice are connected in series and form＜referring to Fig. 5 and Fig. 6 〉, adjusts x, y, z value, can guarantee that then its expansion effect quite or identical.Equally also can be respectively be that 2.3 millimeters, length are x rice with internal diameter, internal diameter is that 2.0 millimeters, length are y rice, internal diameter is that 1.6 millimeters, length are that three sections capillaries of z rice are connected in series and form＜referring to Fig. 5 and Fig. 6 〉, adjust x, y, z value, then can guarantee its expansion effect and internal diameter be 1.73 millimeters, length be 0.8 meter capillary quite or identical.Equally also can be connected in series, by that analogy with the capillary of internal diameter more than three kinds.In general, the adjustment of these length is selected not so difficult, and common refrigerationist can obtain best selection with a spot of experiment.In the large-scale refrigeration of single-stage, aircondition, use two or more expansion valve series connection, its advantage also is this, promptly it can make large-scale refrigeration, air-conditioning system more optimize on thermodynamics.
In the designed a kind of low power air-conditioner of the design person, just used this new multistage expansion assembly.It is a kind of expansion assembly that is composed in series by three grades of capillaries, is respectively that internal diameter is that 2.2 millimeters, length are 0.3 meter, and internal diameter is that 1.9 millimeters, length are 0.4 meter, and internal diameter is that 1.6 millimeters, length are 0.5 meter.Adopt the method for attachment as Fig. 6, from experimental prototype, the expansion effect of this expansion assembly is very good.
