Evaporative cycles of concentration control

A cycles of concentration (COC) control process and system for an evaporative media cooling system having a water storage tank in fluid communication with a drain valve and a refill valve is disclosed. In one step, the COC control process includes the step of executing a plurality of discrete refill events to maintain a level or volume of water within the storage tank. In another step, the COC control process includes the step of executing a discrete drain event, equaling the volume of a refill event, after a discrete refill event has been executed when necessary to maintain a target cycles of concentration value of the water within the storage tank. In one embodiment, a discrete drain event is executed when the number of refill events is greater than or equals a target cycles of concentration of the water in the storage tank.

Staging control for an evaporative media system

A staging control process for an evaporative media cooling system having a plurality of media stages is disclosed. In one step, a leaving air dry bulb temperature setpoint for air exiting the evaporative media cooling system is received or defined. In one aspect, an expected media exit dry bulb temperature is calculated for each media stage based on a dry bulb temperature and a wet bulb temperature of air entering the media cooling system and based on a measured or assigned condition of the media. In another aspect, an estimated combined leaving dry bulb temperature is calculated for different combinations of activated and deactivated media stages. Once the estimated leaving temperature is known, the method can then activate the media stage(s) associated with the combination that has an estimated combined leaving dry bulb temperature that is nearest to but less than the leaving air dry bulb temperature setpoint.
