Project Summary

Two-stage or indirect-direct evaporative cooling technology offers the best opportunity for replacing air conditioning in California. The existing two-stage evaporative cooler on the market does not achieve the full potential of this technology. Previous lab testing has shown an achieved evaporative effectiveness of 88 to 98%. The OASys product, the result of a CEC PIER Program, appears to be able to achieve the technology potential. Lab and fields monitoring has indicated that the OASys technology can achieve evaporative effectiveness from 104 to 111%. For more information, please contact the sponsoring organization.
