Overview of Peak Envelope Cooling Load Methods Using the RTS Method

This presentation will discuss the development of the Radiant Time Series (RTS) Method for performing design cooling load calculations is derived from the heat balance method. In the current ASHRAE Handbook, the RTS method has replaced all other simplified (non-heat-balance) methods such as the Cooling Load Temperature Difference/ Cooling Load Factor/Solar Cooling Load (CLTD/CLF/SCL) method, the Total Equivalent Temperature Difference/Time Averaging method (TETD/TA), and the Transfer Function Method (TFM).
