Evaporative condensers - a new look
Evaporative condensers should be the most efficient and cost effective method of rejecting heat from refrigerating systems. Quantities of air and water required are minimal as is the amount of power required for pumps and fans. Unfortunately, concerns about Legionaires Disease have resulted in onerous requirements for cleaning, maintenance and water treatment. This makes the evaporative condenser difficult and expensive to apply. It is also by no means certain that planning permission will be given for installation of an evaporative condenser.
This paper illustrates a method of operating evaporative condensers on a once-through system that does not require a water tank or pump. Such operation eliminates the possibility of the condenser becoming infected with Legionella. Theoretical calculations and experimental data are given.
