includes a condenser fan 22 driven by an electric motor 24 liquid refrigerant from condenser 20 is then directed to drier filters 26 via a line 25 where moisture is removed from the liquid refrigerant the liquid refrigerant then flows to a tank 33 via a line 27 which includes a check valve 29 where it is stored under high pressure high pressure refrigerant vapor 30 occupies the space above the level of the liquid refrigerant 28 in tank 33 tank 33 is connected to the refrigeration equipment 15 to be cleaned via a line 31 which includes a check valve 32 a normally closed solenoid valve a and a pressure switch ps1 with the connection to equipment 15 from line 31 being indicated at 34 the refrigerant circuit 12 thus includes the refrigeration apparatus or equipment 15 to be cleaned circuit 12 then continues from apparatus 15 to a tank 38 via a second connection 37 to apparatus 15 and a line 39 which includes pressure switches ps2 and ps3 a normally closed solenoid valve b and a check valve 40 the refrigerant entering tank 38 from apparatus 15 is in the form of high and low pressure liquid and it contains any particulate matter or contaminants 42 which may have been picked up during the high pressure flushing of apparatus 15 tank 38 functions to separate the contaminants 42 from the refrigerant by passing the liquid refrigerant through compressor oil 44 tank 38 is designed such that the contaminants 42 gravitate to the bottom of the tank through the compressor oil 44 where they.
