Oil separator for air conditioner

Abstract

An oil separator for an air conditioner includes a cylindrical housing; a refrigerant discharge pipe communicating with the housing for discharging refrigerant gas; an oil discharge pipe for circulating oil collected in the lower portion of the housing; and a refrigerant inflow pipe having one end facing the inner surface of a side wall of the housing in the tangential direction for supplying a refrigerant-oil mixture to the inside of the housing. An insertion hole, into which the refrigerant inflow pipe is inserted, is easily formed, the efficiency of the oil separator is increased, and noise and vibration generated from the oil separator is reduced.

1 . An oil separator for an air conditioner comprising:
 a cylindrical housing;   a refrigerant inflow pipe for supplying a refrigerant-oil mixture to the inside of the housing;   a refrigerant discharge pipe for discharging refrigerant separated from the mixture to the outside of the oil separator; and   an oil discharge pipe for returning oil separated from the mixture to a compressor,   wherein one end of the refrigerant inflow pipe faces the inner surface of a side wall of the housing in the tangential direction,   the refrigerant inflow pipe is bent in a gentle curve at a portion thereof which is inserted into the housing, and   the refrigerant inflow pipe is bent again in the reverse direction to the bent portion so that the refrigerant inflow pipe has an approximately “S” shape.   
   
   
       2 . An oil separator for an air conditioner comprising:
 a cylindrical housing;   a refrigerant inflow pipe for supplying a refrigerant-oil mixture to the inside of the housing;   a refrigerant discharge pipe for discharging refrigerant separated from the mixture to the outside of the oil separator; and   an oil discharge pipe for returning oil separated from the mixture to a compressor,   wherein one end of the refrigerant inflow pipe faces the inner surface of a side wall of the housing in the tangential direction, and   the refrigerant inflow pipe is inserted perpendicularly into a through hole formed through the side wall of the housing.
