Abstract: Apparatus for utilizing waste water from a refrigeration system to cool the motor-compressor and associated coil of condenser tubing in that system. The apparatus features a motor-compressor around which is wrapped the condenser coil. The motor-compressor and condenser coil are contained within a water tank to which is directed waste water that has been collected from the meltdown of an ice making cycle or the condensate from a refrigerant evaporator. In applications where waste water production is insufficient a valve controlled supply of fresh water can be substituted therefor or used in conjunction with the waste water to effect cooling of both the compressor and condenser coils. Use of the waste water in this manner obviates the need for fans and associated motors to provide air-cooling of the condenser and for possible oil cooling of the motor-compressor.
