  • Patent number: 9801964
    Abstract: 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.

  • Patent number: 9675719
    Abstract: 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.

  • Patent number: 9603957
    Abstract: An evaporative media system having multiple media stages each served by a separate pump is disclosed. In one aspect, the evaporative media system has a first media stage and a second media stage. A first pump is provided that is configured to deliver water from the first compartment of the water storage tank to the first media stage. Additionally, a second pump is provided that is configured to deliver water from the first compartment of the water storage tank to the second media stage. Additional media stages and pumps may be provided as well. The disclosed configuration eliminates the need for individual staging valves, provides a higher level of operational redundancy, reduces electrical consumption, and can be provided at a lower cost, as compared to many existing systems.

  • Patent number: 9459055
    Abstract: A heat transfer system includes a steam chamber that communicates in an open-loop arrangement with a first steam source for supplying steam to the steam chamber, the steam chamber including a steam exit for supplying steam to air at atmospheric pressure. A heat transfer tube communicates in a closed-loop arrangement with a second steam source for supplying steam to an interior surface of the heat transfer tube, the heat transfer tube vaporizing condensate forming within the heat transfer system back to steam that is supplied to the air via the steam exit. The outer surface of the heat transfer tube is configured to contact the condensate and vaporize the condensate back into steam, wherein the heat transfer tube includes a plurality of pockets formed on the outer surface of the tube, each pocket including a pocket exit/entry portion having a smaller cross-sectional area than the cross-sectional area of the pocket at a root portion thereof adjacent the outer surface of the tube.

  • Patent number: 9194595
    Abstract: A steam dispersion apparatus includes a steam chamber communicating in an open-loop arrangement with a first steam source for supplying steam to the steam chamber. The steam chamber includes a steam dispersion location at which steam exits therefrom at generally atmospheric pressure. A heat exchanger communicates in a closed-loop arrangement with a second steam source for supplying steam to the heat exchanger at a pressure generally higher than atmospheric pressure. The heat exchanger is located at a location that is not directly exposed to the air to be humidified, the heat exchanger being in fluid communication with the steam chamber so as to contact condensate from the steam chamber. The heat exchanger converts condensate formed by the steam chamber back to steam when the condensate contacts the heat exchanger.
