Definitions
- the refrigerant compressed by the compressor 1 is condensed by the condenser 2 and then sent to the expansion valve 3.
- the gas-liquid two-phase refrigerant exiting the expansion valve 3 is evenly distributed to each heat transfer channel of the evaporator 5 by the refrigerant distributor 4, evaporated in the evaporator 5, and then merged in the header 6. And returned to the compressor 1.
- a conventional refrigerant flow divider includes an inlet pipe, a flow divider body having a hollow inside, and a plurality of branch pipes through which refrigerant flows (see Patent Document 1).
- Patent Document 1 there is an apparatus in which an uneven flow is reduced by increasing the flow rate of the two-phase refrigerant by installing an orifice or nozzle in the flow divider or in the inlet pipe (see Patent Document 2).
- Patent Document 1 Japanese Utility Model Publication No. 60-2775.
- Patent Document 2 Japanese Patent Application Laid-Open No. 2002-188869.
- the refrigerant flow distributor disclosed in Patent Document 2 has a disadvantage that the pressure loss in the flow distributor increases and the control range of the refrigerant flow control valve is reduced.
- the present invention has been made in view of the above points, and an object of the present invention is to provide a refrigerant shunt that can distribute the refrigerant evenly and has a small pressure loss.
- the ratio of length L to inner diameter D is set so that 2 ⁇ L / D ⁇ 8.
- the liquid pool in the lower part increases, in other words, as the gas-liquid interface rises, branching occurs due to misalignment of the installation angle or misalignment of the plug insertion (the insertion allowance of the branch pipe)
- the gas-liquid distribution ratio of the refrigerant discharged from the pipe becomes different in each path, and refrigerant drift occurs.
- the type of refrigerant flow divider can be selected according to the capacity class of the refrigeration system, making it easier to select the refrigerant flow divider.
- FIG. 2 is a longitudinal sectional view of a refrigerant flow divider that is useful for an embodiment of the present invention.
- FIG. 3 is a plan view showing a state in which a branch pipe of the refrigerant distributor in FIG. 2 is removed.
- FIG. 5 The change in the variation in the flow rate ratio (deviation) for D 2 / G in FIG. 5 refrigerant flow divider of Figure 2
- FIG. 1 A first figure.
- the refrigerant flow divider of the present invention is used in the refrigeration apparatus shown in Fig. 1 as in the prior art.
- an inlet pipe 12 into which refrigerant Xin flows is provided.
- the shunt body 11 has a hollow inside, and a plurality of (for example, four) branch pipes 13 from which the refrigerant Xout flows out.
- the shunt body 11 includes a connecting portion 11a to which the inlet pipe 12 is connected, a diameter of the connecting portion 11a, an enlarged diameter portion l ib whose diameter gradually increases, and a maximum diameter of the enlarged diameter portion l ib And a cylindrical portion 11c having the same diameter.
- a branch pipe connecting portion 11d protruding outward is provided at the top of the cylindrical portion 11c, and a plurality of holes 14 for inserting the branch pipes 13 are equiangularly spaced at the connecting portion id. Is formed.
- the length of the current divider body 11, that is, the distance from the boundary position between the connecting portion 11a and the enlarged diameter portion l ib to the highest inner surface of the branch pipe connecting portion 11d is Lmm
- the inner diameter of 11, that is, the inner diameter of the cylindrical portion 11c is D mm
- the ratio of length L is set so that 2 ⁇ L / D ⁇ 8.
- the installation angle varies by about ⁇ 10 °, and the dryness of the inlet refrigerant.
- the range of 2 ⁇ L / D ⁇ 8 is good for the variation (deviation) of the flow rate ratio to be 0 ⁇ 1 or less. Note that the variation (deviation) in flow rate ratio is more severe.
- the range is 3 ⁇ LZD ⁇ 6.
- the liquid pool at the lower part increases due to the influence of gravity.
- the interface between the gas and liquid rises, resulting in misalignment of the installation angle and the insertion cost of the cable (in other words, the branch pipe 13)
- the gas-liquid distribution ratio of the refrigerant discharged from the branch pipe 13 becomes different in each path, and refrigerant drift occurs.
- the inner diameter D of the cylindrical portion 11c can be replaced by the following formula in each class.
