Title:
REFRIGERANT COMPRESSOR EQUIPPED WITH ACCUMULATOR AND VAPOR COMPRESSION-TYPE REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/026496
Kind Code:
A1
Abstract:
Provided is a refrigerant compressor equipped with an accumulator with which pressure loss is reduced while maintaining gas-liquid separation performance. The refrigerant compressor (10) equipped with an accumulator is equipped with: an accumulator-type sealed container (11); a inlet pipe (12) wherein refrigerant flows from an aperture part (12a) at an end portion thereof to the accumulator-type sealed container (11); an outlet pipe (13) wherein refrigerant is sucked from an aperture part (13a) at an end part thereof; an inlet pipe flow guide (41) that is arranged in an upstream space (21), forming a diffuser-shaped flow path (40-1) the cross section of which gradually increases from a position near the aperture of the inlet pipe (12) toward the downstream side of the inflow direction (335c) of the refrigerant, with the refrigerant that flows in then flowing out from the diffuser-shaped flow path (40-1); and a bent flow guide (31) that has slanted faces and is arranged at a position downstream from the diffuser-shaped flow path (40-1), thus separating the interior space into the upstream space (21) and a downstream space (22), and blocking the flow in the inflow direction of the refrigerant from the inflow pipe that flows out from the diffuser-shaped flow path (40-1).
