Embodiment 1

[0025] An embodiment of the present invention will be described in detail based on the drawings. figure 1 A refrigerant circuit diagram of a refrigeration system according to an embodiment of the present invention is shown. The refrigerating apparatus 30 includes a compressor 1, a radiator 2 connected to the discharge side of the compressor, an expansion valve 3 connected to the outlet side of the radiator 2, and a gas-liquid separator connected to the outlet side of the expansion valve 3. 4. The heat absorbing mechanism 8 and the oil separator 5 through which the liquid refrigerant separated by the gas-liquid separator flows, the refrigerant piping 4C through which the gas refrigerant separated by the gas-liquid separator 4 flows, and the intermediate pressure part of the compressor 1 Connected, the outlet side of the heat absorbing mechanism 8 is connected with the suction port of the compressor 1 to form a refrigeration cycle. In addition, a check valve 7 is provided in th...

Embodiment 2

[0059] Below, refer to Figure 4 Other embodiments of the present invention will be described. Figure 4 A refrigerant circuit diagram of the refrigeration device 50 at this time is shown. In this embodiment, the configurations with the same symbols as in the first embodiment described above have the same or similar functions or effects. In this embodiment, compared with the above-mentioned Embodiment 1, the difference is that instead of the heat absorption mechanism 8, the outlet side of the three-way valve 91 has a first heat absorption mechanism 10 and a second heat absorption mechanism arranged in parallel therewith. agency11.

[0060] The first heat absorbing mechanism 10 includes a first capillary 12 and a first heat absorber 57 provided in series with the first capillary 12 . In addition, the second heat absorbing mechanism 11 includes a second capillary 13 , a second heat absorber 58 provided in series with the second capillary 13 , and a check valve 52 . In additi...

Embodiment 3

[0066] Below, refer to Figure 6 Still another embodiment of the present invention will be described. Figure 6 A refrigerant circuit diagram of the refrigeration device 70 at this time is shown. In addition, in Figure 6 In , the configurations with the same symbols as in the first and second embodiments described above have the same or similar functions or effects. The refrigerating device 70 of this embodiment is different from the above-mentioned embodiment 2 in that there is no three-way valve 91, and instead of the first heat absorption mechanism 10 and the second heat absorption mechanism 11, a third heat absorption mechanism 10B is provided. The fourth heat absorbing mechanism 11B also has a three-way valve 92 as a flow path switching mechanism, and a refrigerant pipe 92A drawn from the three-way valve 92 is connected to the above-mentioned refrigerant pipe 4C.

[0067] The third heat absorbing mechanism 10B includes a first expansion valve 65 as a decompression mec...

Abstract

An object is to provide a refrigerating device capable of realizing a high-efficiency operation in a case where a compressor having an intermediate pressure section is applied, and a refrigerator including this refrigerating device. A refrigerating device 30 includes: a compressor 1; a radiator 2; an expansion valve 3; a gas-liquid separator 4; and a heat absorbing unit 8 through which a liquid refrigerant discharged from this gas-liquid separator circulates. The refrigerating device further includes: a refrigerant pipe in which the refrigerant discharged from the heat absorbing unit 8 can be introduced into a suction port of the compressor 1 and which introduces a gas refrigerant separated by the gas-liquid separator 4 into the intermediate pressure section of the compressor 1; and a refrigerant pipe which introduces an intermediate-pressure refrigerant of the compressor 1 into the gas-liquid separator 4.

Description

technical field [0001] The present invention relates to a refrigerating device equipped with a mechanism capable of introducing gas refrigerant separated by a gas-liquid separator into an intermediate pressure section of a compressor, and a refrigerator provided with the refrigerating device. Background technique [0002] It is known that a refrigeration device generally includes a two-stage compressor, a radiator, a pressure reducer, and a gas-liquid separator, and a gas refrigerant separated by the gas-liquid separator is introduced between the first stage and the second stage of the above-mentioned compressor. The mechanism of the intermediate pressure part (refer to Patent Document 1). In such a refrigeration system, since the gas refrigerant separated by the gas-liquid separator is introduced into the intermediate pressure section of the compressor in a gaseous state, the efficiency of the compressor can be improved. [0003] Patent Document 1: JP-A-2003-106693 [000...
