Proposed ASHRAE Standard 212 is a Method of Test for determining the energy and peak electricity demand savings associated with adding evaporative pre-coolers to packaged HVAC equipment. The standard measures the evaporative effectiveness of a pre-cooler as a function of face velocity and weather conditions, as well as the water consumption required to produce that effectiveness. This presentation will discuss the current content of the standard, as well as the rationale for how and why different parameters are measured within the standard. It will also include preliminary test results for different pre-cooler technologies.
