する。2. Description of the Related Art In an air conditioner such as a heat pump, when a gas phase is mixed in the refrigerant liquid, especially when there are a plurality of internal units, each internal unit has The performance is significantly reduced because the refrigerant is not evenly distributed.

度が増大するという問題も存在する。On the other hand, there is known a technique for increasing the degree of supercooling of the refrigerant liquid in order to prevent the refrigerant from vaporizing into a gas-liquid two-phase. However, with the above method of increasing the degree of supercooling of the refrigerant liquid, it is difficult to prevent the refrigerant from vaporizing into the gas-liquid two-phase when the length of the pipe is long, and it has not been possible to sufficiently cope with it. . There is also a problem that the degree of superheat of the refrigerant gas after heat exchange is increased.

いる。In addition to this, in the case of a refrigerant, it has a property of being vaporized immediately when it collides in a liquid state. And
If the flow velocity is not kept below a certain level, the pressure loss when flowing through the pipe will become extremely large. Therefore, there is a problem that it is impossible to use the gas-liquid separation device used in the usual handling of liquids for the refrigerant.

In a gas-liquid separator for a refrigerant that separates a gas-liquid two-phase refrigerant of an air conditioner, a mesh-shaped member and a gas recovery unit are provided at the upper end of an inner cylinder having an opening on the upper side surface, An outer cylinder that shares a bottom plate outside the inner cylinder and is provided concentrically with the inner cylinder, and an inflow that is arranged so as to face the inner side surface at the bottom of the inner cylinder and is offset with respect to the diameter. A plurality of liquid outlets including a pipe are provided above the side surface of the inner cylinder to allow a liquid flowing in the inner cylinder to flow into a flow passage formed in a gap between the inner cylinder and the outer cylinder.

突による冷媒が気化することはない。According to the gas-liquid separator for a refrigerant of the present invention constructed as described above, the refrigerant of gas-liquid two-phase flow is introduced into the inner cylinder by the introduction pipe provided in an offset manner, and the refrigerant of the inner cylinder is discharged. It becomes a swirling flow along the inner wall and gradually decelerates and gradually rises. At this time, since the refrigerant does not collide with the inner cylinder wall surface, the refrigerant is not vaporized due to the collision.

る。When a swirl flow is generated and the inner cylinder is raised, the cross-sectional area of the inner cylinder is much larger than the cross-sectional area of the introduction pipe. It is very slow compared to the flow velocity flowing in the tube. On the other hand, since the specific gravities of the refrigerant gas and the refrigerant liquid are different, the bubbles of the refrigerant gas separate from the refrigerant liquid and rise, and are recovered in the gas recovery section in the upper part of the inner cylinder. When the refrigerant gas is recovered by the gas recovery unit, the refrigerant liquid scattered along with the gas is recovered and dropped by the liquid smoothing device formed of the mesh member.

戻って流出管より流出する。On the other hand, when the refrigerant liquid separated from the refrigerant gas enters the flow path formed in the gap between the inner cylinder and the outer cylinder from the plurality of outlets formed in the inner cylinder and flows through the inflow pipe. It returns to the flow velocity of and flows out of the outflow pipe.

In the case where the liquid level of the outer cylinder reaches a predetermined constant level when the separated refrigerant gas accumulates above a certain amount at the upper end of the outer cylinder, The on-off valve is opened based on the signal from the liquid level detector which is the detection means, and the refrigerant gas decompressed by the pressure reducer is returned to the low pressure gas circuit to close the on-off valve.

Further, a plurality of liquid outlets 4 are opened in the upper portion of the side surface of the inner cylinder 1. The outer cylinder 6 that shares the bottom plate 5 of the inner cylinder 1 is provided concentrically with the inner cylinder 1 in such a manner as to surround the outer peripheral side surface of the inner cylinder 1. On the bottom side surface of the inner cylinder 1, an outer pipe 6 and the inner cylinder 1 are watertightly penetrated, and an introduction pipe 7 is offset and fixed as shown in the drawing (with respect to a diameter of a circular cross section). 8 are offset (disposed so as to face the introduction pipe 7) and fixed.

Is connected to drive means 14 for driving the on-off valve 11.

流となる。The gas-liquid two-phase refrigerant introduced into the inner cylinder 1 from the unillustrated refrigerant liquid circuit of the air conditioner such as a heat pump through the introduction pipe 7 is the inner cylinder wall as shown by an arrow A in FIG. A swirling flow follows along and slowly rises in the B direction (FIG. 1). At this time, since the introduction pipe 7 is offset with respect to the diameter of the circular cross section of the inner cylinder 1, the refrigerant liquid discharged from the introduction pipe 7 does not directly collide with the inner side surface of the inner cylinder 1, and Since the direction is changed along the curved surface of the inner surface, a swirling flow is formed.

回収部３に回収される。Here, the flow velocity of the refrigerant liquid flowing through the introduction pipe 7 is in the range of 1.5 to 2.0 m / sec. Then, the flow velocity of the refrigerant liquid introduced into the inner cylinder 1 is reduced to 1.3 m / sec or less. This speed is determined by the ratio of the cross-sectional areas of the introduction pipe 7 and the inner cylinder 1. On the other hand, since the specific gravity of the refrigerant gas is smaller than that of the refrigerant liquid, the bubbles are separated from the refrigerant liquid and recovered in the gas recovery section 3.

前の速度に復元することが出来る。The refrigerant liquid from which the bubbles of the refrigerant gas have been separated passes through the liquid outlet 4 as shown by arrows C and D in FIG.
It flows into an annular flow path formed between the inner peripheral surface and the outer peripheral surface of the inner cylinder 1. Here, the flow velocity of the refrigerant liquid represented by the arrow D is introduced by appropriately setting the diameters of the inner peripheral surface of the outer cylinder 6 and the outer peripheral surface of the inner cylinder 1 to determine the cross-sectional area of the annular flow path. It can be set equal to the flow velocity in the pipe 7. In other words, the flow velocity can be restored to the velocity before gas-liquid separation by the optimally determined dimensions of the inner cylinder and the outer cylinder.

Then, when the refrigerant gas is separated and becomes a predetermined constant value or more and the liquid level detector 13 detects the liquid level of the refrigerant liquid in the outer cylinder 6, the liquid level detector 13 generates a signal,
Drive means 14 for driving the on-off valve 11 based on the signal
Opens the on-off valve 11. As a result, the refrigerant gas flows into the decompressor 12, where it is decompressed and returns to the gas circuit (not shown). When the amount of gas decreases, the liquid level detector 13 no longer detects the liquid level of the refrigerant liquid, and the on-off valve 11 is closed.
