Carlsbad, CA – December 26, 2012 — The Emerging Technologies Coordinating Council (ETCC) has posted AESC’s technology assessment report for Evaporative Retrofit Components for Roof Top Packaged Air-conditioning Units. In this study conducted for Pacific Gas and Electric, AESC evaluated three emerging evaporative cooling technologies using field test results obtained from six test sites. The technologies evaluated included: 1) Outdoor Air Supply (OAS) evaporative pre-cooling; 2) condenser air evaporative pre-cooling; and 3) integrated systems implementing both 1 and 2. AESC’s findings identified energy and demand savings achieved by reducing the compressor’s cooling load or by increasing the vapor compression cycle efficiency, and performance sensitivities related to the quality of design and installation.
