We propose a method for cooling the condenser compression refrigerator, including the use of melt water wetting the surface of the water condenser. The water is directed into the groove in the middle part of which is the tube condenser coil, and the water flows by gravity to the tribes of the inclined groove, wetting the surface of the trough and tube condenser. Remains of meltwater routed to the tank on the compressor.
