Title:
ACCUMULATOR AND REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/064813
Kind Code:
A1
Abstract:
Disclosed are an accumulator and the like that can return oil without complicating circuit architecture or consuming energy. The disclosed accumulator (6) performs vapor-liquid separation and accumulates the liquid in order to supply a refrigerant in a vapor phase to a compressor (1) in a refrigeration cycle device. The accumulator is provided with: a vessel (A) for accumulating the liquid; an inflow pipe (B) via which a refrigerant, which circulates through a refrigeration circuit, flows into the vessel (A); a distribution coupling (G) for distributing, in a plurality of directions, the refrigerant which has flowed into the inflow pipe (B); a branching pipe (I) that leads the distributed refrigerant to the bottom of the vessel (A) such that the refrigerant agitates the liquid accumulated in the vessel (A); and an outflow pipe (C) that has an oil-return hole (D) out which the refrigerant flows along with refrigerant oil in the liquid accumulated in the vessel (A).
