HO-82-04-1 -- Evaluating Design Temperatures for HVAC Applications in Extreme Climates

Extreme temperatures and their duration related to design applications are the main points which will be addressed in this paper. It will present a new concept for designing and/or sizing air-conditioning (or heating) systems. But first, it will address some aspects of temperature statistics. Next, a brief mathematical review of extreme temperature analysis and its relation to "return period" will be presented. Finally, a new "duration design temperature" will be introduced and discussed in detail.
