Abstract

1333186 Refrigerating BORG WARNER CORP 27 May 1971 [17 June 1970] 17569/71 Heading F4H A closed-circuit refrigeration system comprises an evaporator 10, a condenser 11, and a driven compressor 12; a lubricant sump 19 and pump 22 for supplying lubricant under pressure to the compressor 20, gearing 17 and motor 18; and means 25 for purging the system of non- condensible gases, particularly air; The means 25 includes a chamber 27 having an inlet duct 28 to receive refrigerant vapours and non- condensible gases from the system, a heat exchange coil 30 for circulating refrigerant through the chamber to condense refrigerant vapour flowing from the inlet duct 28, a valve 35 for diverting lubricant under pressure from the lubricant circuit into the chamber 27 to compress the non-condensible gases, and a relief valve 33 for controlling evacuation of the compressed gas through the gas outlet to the atmosphere. Mounted within chamber 27 are two float devices 38 and 40, each arranged to actuate hermetically enclosed switches 39 and 41. The switches 39 and 41, and a solenoid operator 49 connected to valve 35, are connected in an electrical circuit, such that upon drop of a liquid level to float 40, the operator is energized, allowing oil to flow into chamber 27. Upon rise of a liquid level to float 38, the valve is de-energized, allowing liquid in the chamber to drain into sump 19.
