ABSTRACT:
The present invention relates to a method and apparatus for operating an evaporative condenser refrigeration system at a low condensing temperature. The refrigeration system includes a condenser, an evaporator, a compressor, and a coolant flowing therethrough. The condenser is sized for sufficient capacity for operation at the annual average wet bulb temperature of the locality of the refrigeration system. The evaporative condenser is operated at full capacity at all times during operation of the refrigeration system. The temperature of the incoming coolant fluid to the condenser is permitted to follow the prevailing wet bulb temperature of the locality. By operating at a low condensing temperature, a compressor arranged in the refrigeration system operates at the lowest practical horsepower requirement. Further, according to the preferred embodiment of the present invention the capacity of a compressor delivering working fluid to the condenser is controlled to ensure that the desired refrigeration load on the evaporator is maintained while using the minimum required compressor horsepower.
