Abstract

A circulating cold water cooler-chiller comprised of a water holding tank, refrigerant cooling/thermal electric unit and a circulating pump system. The water in the water tank is cooled by coolant coils in bottom of tank and the water is circulated by an electric pump. The temperature is controlled by a thermostatic control that has a sensor in the water so as to control the refrigerant compressor/thermal electric unit operation letting the water circulation be separate and continuous at all times. Constant temperature is maintained by this type of configuration.
