SEER Rating for Evaporative Coolers in Hot and Dry Climates
November 11, 2005
The RESNET Technical committee concurred that evaporative coolers can
be more efficient than standard air conditioner coolers. Because of the
lack of identified standards to create a SEER equivalency the committee
decided to be conservative on the issue until more information can be
found. The committee agreed to interpret the standards in such a manner
that evaporative coolers would be assigned a SEER of 15. The committee
will contact the California Energy Commission to see how Title 24
addresses evaporative coolers with the option of increasing the SEER
rating if treated as such in Title 24. |
