Abstract:
A refrigeration system that utilizes both an air-cooled heat exchanger and a cooling tower to cool refrigerant prior to the refrigerant being provided to the evaporator. This multi-stage cooling permits the refrigeration system to operate with improved efficiency, while reducing the amount of water lost to evaporative cooling in the cooling tower, since the thermal load handled by the cooling tower is reduced by the air-cooled heat exchanger. This in turn means less water is required to replace water lost to evaporative cooling. In arid regions or regions of low water quality, both efficiency increase and reduction of water lost to evaporative cooling are important improvements.
