Abstract

PURPOSE: To distribute a refrigerant uniformly when a distributor is set in the horizontal or inclining direction by fixing the inlet while shifting it upward of the gravitational direction from the center line of a hollow body in the flow- out direction of refrigerant. CONSTITUTION: When a refrigerant distributor is set in an inclining or horizontal direction, a liquid phase B2 heavier than a gas phase B1 tries to flow more toward an outlet 8b on the oblique lower side in a hollow body 6 under influence of gravity (h). When an inlet 7 is fixed to one end of the hollow body 6 at a position higher by the width C than the center line (n), the liquid phase B2 also flows easily toward an upper outlet 8a close to the line direction. Consequently, the gravity (h) and the width (c) of eccentricity are balanced and the liquid phase B2 flows uniformly toward the upper and lower outlets 8a, 8b resulting in uniform distribution of refrigerant B to a delivery pipe 10.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a refrigerant flow divider for uniformly dividing refrigerant in a refrigeration cycle of an air conditioner, a refrigeration equipment, or the like.

Conventional technology In recent years, refrigerant flow dividers have been used more frequently in order to cope with the multiplication of refrigeration systems and the creation of multiple circuits due to the smaller diameter heat exchanger tubes, and the amount of heavy use of refrigerant flow dividers has increased. .

Hereinafter, the conventional refrigerant flow divider mentioned above will be explained with reference to the drawings.

Figures 6 and 7 show the shapes of conventional refrigerant flow dividers;
The figure shows its used state in the horizontal direction. In Figures 6 to 8, 1 is a hollow body forming the outer shell of the refrigerant flow divider, with a single inlet 2 at one end and a single inlet 2 at the other end. 2 outlets 3
It is equipped with Further, the inlet port 2 is located on the center line m of the hollow body 1 in the refrigerant outflow direction and is attached to one end of the hollow body 1. Furthermore, an inflow vibrator 4 is inserted into the inflow port 2, and an outflow vibe 5 is inserted into the outflow port 8, respectively.

Regarding the refrigerant flow divider configured as above, the following section 8.
The operation will be explained using diagrams.

The refrigerant A flowing through the inflow vibrator 4 becomes a two-phase flow of a gas phase A1 and a liquid phase A2 and flows into the hollow body 1 from the inlet port 2. After being mixed with gas and liquid to some extent within the hollow body 1, the refrigerant A flows through the inflow port 3. The flow is divided at the flow point and flows out to the outflow vibrator 5.

Problems to be Solved by the Invention However, in the above configuration, the refrigerant flow divider f! :
When installed in an inclined direction or in a horizontal direction as shown in Fig. 8, the liquid phase A2, which is heavier than the gas phase A1, flows to the lower outlet 3b and flows to the upper outlet 3a under the force of gravity g. Since the refrigerant A does not flow much, there is a problem in that the refrigerant A cannot be evenly distributed to the outflow vibrator 5.

In view of the above-mentioned problems, the present invention provides a refrigerant flow divider that can evenly divide the flow of refrigerant when installed in an inclined or horizontal direction.

Means for Solving the Problems In order to solve the above problems, the refrigerant flow divider of the present invention has an inlet that is installed eccentrically above in the direction of gravity with respect to the center line of the hollow body in the refrigerant outflow direction. It has a configuration.

Effect of the Invention With the above-described configuration, the present invention prevents the refrigerant flowing from the inlet when the refrigerant flow divider is installed in an inclined or horizontal direction from flowing too much to the outlet at the lower side due to the influence of gravity. By adjusting the eccentricity of the inlet installation, equal flow distribution can be achieved.

EXAMPLE Hereinafter, a refrigerant flow divider according to an example of the present invention will be described with reference to the drawings.

1 and 2 show the shape of a refrigerant flow divider according to an embodiment of the present invention, and FIG. 3 shows its use when placed horizontally. In FIGS. 1 to 3, 6 is a hollow body forming the outer shell of a refrigerant flow divider, and is provided with a single inflow lower at one end and two outlet ports 8 at the other end. Further, the inflow lower is mounted eccentrically by a width C above the center line n of the hollow body 6 in the refrigerant outflow direction. Further, an inflow vibrator 9 is inserted into the inflow lower, and an outflow pipe 10 is inserted into the outflow port 8.

Regarding the refrigerant flow divider configured as above, the following is the third section.
The operation will be explained using diagrams.

The refrigerant B flowing through the inflow pipe 9 becomes a two-phase flow of a gas phase B1 and a liquid phase B2, flows into the hollow body 6 from the inflow lower part, is mixed with gas and liquid in the hollow body 6, and is then separated at the outlet 8. and leaks out to the outflow vibrator 10.

At that time, when installed in an inclined direction or horizontal direction as shown in Figure 3, the liquid phase B is heavier than the gas phase B1 due to the influence of gravity.
2 tends to flow to the obliquely lower outlet 8b within the hollow body 6, but because the inflow lower is eccentrically attached to one end of the hollow body 6 by the width C above the center 1lQn. Then, the liquid phase B2 becomes easier to flow to the upper outlet 8a which is close to the straight line direction, and eventually the gravity and the eccentric width C are balanced, and the liquid phase B2 flows out equally to the upper and lower two outlet outlets 8a and 8b. Therefore, the refrigerant B can be evenly divided into the outflow pipe 10.

As described above, according to this embodiment, by installing the inflow lower eccentrically above the center line n of the refrigerant outflow direction of the hollow body 6, when the refrigerant flow divider is installed horizontally or in an inclined direction, the refrigerant B It is possible to divide the flow evenly.

Further, in this embodiment, the refrigerant B is a two-phase flow, but the refrigerant B may be a single-phase flow in a gas phase or a liquid phase.

In this embodiment, there are two refrigerant outlets 8, but the number of refrigerant outlets 8 may be three as shown in FIG. 4 or four as shown in FIG. 5.

Effects of the Invention As described above, the present invention has an inlet that is installed eccentrically above the center line in the direction of gravity in the refrigerant outflow direction of the hollow body, so that when the refrigerant flow divider is installed horizontally or in an inclined direction, the refrigerant flow is reduced. It is possible to divide the flow evenly.
