ASHRAE 216-2020

ASHRAE Standard 216 provides standardized performance data for the application of overhead circulation fans in indoor spaces. The room air speed distribution test results can be used to calculate occupant thermal comfort and to demonstrate compliance with the thermal comfort requirements of ASHRAE Standard 55.This standard includes requirements for test instrumentation, test room features, and measurement procedures. It also includes calculation procedures for a number of performance metrics relevant to thermal comfort application of overhead circulator fans, such as uniformity, room average cooling effect, heating draft risk, and comfort cooling efficacy.
