REFRIGERATING PLANT WITH COOLING SYSTEM NOT EQUIPPED WITH PUMP Russian patent published in 2007 - IPC F25B1/00 

FIELD: refrigerating engineering.

SUBSTANCE: proposed refrigerating plant includes compressor, condenser, receiver, adjusting valve and air cooler. Receiver is provided with coil; it may combine function of liquid separator, linear and drainage receivers. Compressor is used for suction of cooling agent vapor from receiver. Vapor from air cooler is admitted to receiver. When condenser of heat exchanger is overfilled with liquid cooling agent, it is automatically discharged to receiver. At removal of snow from air cooler surface, condensate is drained into receiver. For preheating liquid in receiver, use is made of flat flexible heating element manufactured from non-metallic resistive materials; it is connected and disconnected by command from level relay.

EFFECT: reduced power requirements; low cost of refrigerating plant; enhanced safety.
