Title:
OIL SEPARATOR AND REFRIGERATION CYCLE DEVICE OUTDOOR UNIT
Document Type and Number:
Japanese Patent JP2014196855
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve oil separation efficiency by suppressing an oil separator from whirling up an oil reservoir, and solving such problems as poor lubrication of a compressor and degradation in heat transfer efficiency of a condenser and an evaporator.SOLUTION: An oil separator 12 separating oil from a refrigerant mixed with the oil comprises: a closed vessel 12a; an inlet tube 12c for introducing the refrigerant into the closed vessel 12a; a branch tube 12d branching a flow of the refrigerant flowing in the oil separator 12 via the inlet tube 12c, causing the refrigerant to flow into the closed vessel 12a from outlet ports Oand O, and generating a swirl flow in the closed vessel 12a; and an outlet tube 12b causing the refrigerant flowing out of the branch tube 12d into the closed vessel 12a to flow out of the closed vessel 12a. One end of the inlet tube 12c is connected to a hole on a side surface of the branch tube 12d, the refrigerant flowing out of the inlet tube 12c collides against a collision surface S in the branch tube 12, a direction of a segment L on the collision surface S extending along a tube axis Aof the branch tube 12d is inclined with respect to a direction of a tube axis Aof the inlet tube 12c.
