Abstract
In order to prevent wasteful cooling fan energization when the radiator or condensor of an evaporative type cooling system is partially filled in a manner which hinders heat exchange promotion and defeats any merit derived by operating a fan at full power, the fan is operated at a lower level to reduce fan noise and power consumption.
