Project Info COMPLETE Project Title

Evaporative Retrofit Components for Roof Top Packaged Air-conditioning Units

Project Number ET12PGE3181 Organization PG&E End-use HVAC Sector Commercial Project Year(s) 2012 - 2012
Description
In this study, three emerging evaporative cooling technologies were evaluated using the field test results obtained from six test sites. They are: 1) Outdoor Air Supply (OAS) evaporative pre-cooling; 2) condenser air evaporative pre-cooling; and 3) integrated systems implementing both 1 and 2. Savings are achieved either by reducing the cooling load on the RTU compressor(s) because supply air is pre-cooled or by increasing the vapor compression cycle efficiency because condenser air is cooled by direct evaporation.
