Indirect evaporative systems can make the summer peak electrical demands go away 13 January 2016
Throughout western US, particularly in the southwest and California, peak electrical demands during hot summers are extremely expensive for utilities and customers. These peaks are primarily driven by conventional air conditioning which drops in efficiency just when relief from the heat is most needed.
In positive contrast, indirect evaporative systems operate more efficiently the hotter and dryer it gets going beyond wet bulb temperature approaching dew point. Tested by UC Davis’ Western Cooling Energy Center (WCEC) three years ago, two indirect evaporative systems provided EER’s of 44.3 and 45.2 in Bakersfield California.
