Abstract
A method of controlling the operation of an evaporative air cooler where the pads (2) of the cooler are intermittently wetted with an amount of water (14) in excess of the capacity of the pads (2) to absorb and retain during each wetting operation of the pad. The airflow (20) through the pads during intermittent wetting being limited to a velocity so as to not entrain water in the airflow during the wetting operation and the velocity of the airflow through the pads is increased after each intermittent wetting so as to raise the level of cooling output (22) of the cooler between each intermittent wetting operation.
