Part load regulation for evaporation cooling towers in refrigeration plants - using new development of progressive removal of cooling limit range to give output physical characteristic with decreasing water temp. in flow regulation

摘要

The new development is used in the regulation of the air and water flow amounts for altering the heat transmission output. The physical output characteristic is theoretically computed according to DIN 1947, and thereafter is introduced for control. The electrical and electronic regulating plant contains the physical characteristic of the evaporation cooling plant as fixed wired or freely programmed control. The physical output characteristic is also used for regulating of combined wet-dry cooling towers (hybrid cooling towers). ADVANTAGE - Correct characteristic for part load behaviour of evaporation cooling tower is introduced in refrigeration plant.
