Embodiment approach 1

[0082] As shown in FIG. 1, the refrigeration apparatus 1 of this embodiment is an apparatus which performs refrigeration operation in a refrigerator. The refrigerating device 1 includes a refrigerant circuit 10 that performs a two-stage compression and two-stage expansion refrigeration cycle.

[0083]

[0084] The refrigerant circuit 10 includes a low-stage compressor 11, a high-stage compressor 12, a refrigeration heat exchanger 13, an outdoor heat exchanger 14, a main expansion valve 17, an intermediate expansion valve 15, and a gas-liquid separator as a feature of the present invention. 18.

[0085] The discharge side of the low-stage compressor 11 is connected to the suction side of the high-stage compressor 12 . The low-stage compressor 11 and the high-stage compressor 12 are constituted by, for example, scroll compressors.

[0086] The refrigeration heat exchanger 13 is installed in the refrigerator, and the refrigeration heat exchanger 13 is configured as an evapora...

Embodiment approach 2

[0126] Same as the first embodiment, this embodiment is a refrigeration device that includes a refrigerant circuit that performs a two-stage compression and two-stage expansion refrigeration cycle and performs refrigeration operation in the storehouse. Only the configuration of the gas-liquid separator 18 in the refrigerant circuit is the same as The first embodiment is different.

[0127] Such as Figure 5 As shown, the gas-liquid separator 18 of this embodiment is formed such that the dimension in the longitudinal direction on the horizontal plane of the container body 16 is larger than the dimension in the vertical direction. In addition, the mesh member 50 which is a refiner is not provided in the inflow pipe 20 of the said gas-liquid separator 18. As shown in FIG.

[0128] Specifically, the container body 16 of the gas-liquid separator 18 is installed so that the cylindrical container body 16 of the first embodiment is placed horizontally so that the axial direction of t...

Abstract

The invention discloses a gas-liquid separator and a refrigeration deivce with the same. A refrigeration device has a gas-liquid separator (18) and a refrigerant circuit for performing a two-stage compression, two- stage expansion refrigeration cycle. In the refrigeration circuit, an intermediate-pressure, gas-liquid two-phase refrigerant passed from an outdoor heat exchanger to an intermediate expansion valve is introduced into a container body (16) via an inlet tube (20) of the gas-liquid separator (18) and separated into liquid refrigerant and gas refrigerant. The liquid refrigerant flows out of a liquid outlet tube (30), flows through a refrigerant heat exchanger via a main expansion valve, and is then drawn into a low-stage-side compressor. The gas refrigerant flows out of a gas outlet tube (40) to be supplied to the suction side of a high-stage-side compressor and is then drawn into the high-stage-side compressor together with refrigerant discharged from the low-stage-side compressor. A mesh member (50) for breaking up bubbles (80) formed of the gas refrigerant in the gas-liquid two-phase refrigerant is provided in the inlet tube (20).

Description

technical field [0001] The present invention relates to a gas-liquid separator for separating gas-liquid two-phase fluid into liquid fluid and gaseous fluid, and a refrigeration device including a refrigerant circuit having the gas-liquid separator. Background technique [0002] Conventionally, among refrigeration systems, there is a refrigeration system including a refrigerant circuit that performs a two-stage compression and two-stage expansion refrigeration cycle. Furthermore, such a refrigeration system includes a refrigeration system having a gas-liquid separator for separating a gas-liquid two-phase fluid into a liquid fluid and a gaseous fluid (for example, Patent Document 1). [0003] The refrigerator described in Patent Document 1 is an air conditioner including a refrigerant circuit that performs a two-stage compression and two-stage expansion refrigeration cycle during a heating operation. In the refrigerant circuit, a gas-liquid separator is provided for separat...
