Patent ID: 7497091

Claim:
A refrigeration apparatus, comprising (a) a refrigerant circuit ( 10 ) for execution of a vapor compression refrigeration cycle including a compressor ( 21 ), a heat source side heat exchanger ( 24 ), and a utilization side heat exchanger ( 33 ) which are connected by a refrigerant pipe and (b) a contaminant recovery receptacle ( 40 ) which is connected to the suction side of the compressor ( 21 ) by an inflow pipe ( 42 ) and an outflow pipe ( 43 ), for recovering contaminants in the recovery receptacle ( 40 ) by causing refrigerant to circulate in the refrigerant circuit ( 10 ) so that gaseous refrigerant flows into the recovery receptacle ( 40 ), wherein the inflow pipe ( 42 ) has an exit end which opens downwardly or obliquely downwardly in the recovery receptacle ( 40 ) while, on the other hand, the outflow pipe ( 43 ) has an entrance end which is situated above the exit end of the inflow pipe ( 42 ) in the recovery receptacle ( 40 ), and wherein a baffle plate ( 44 ) against contaminants is so disposed as to be situated face to face with the entrance end of the outflow pipe ( 43 ) at a predetermined distance apart therefrom in the recovery receptacle ( 40 ).
