The Radiant Time Series Cooling Load Calculation Procedure

The radiant time series method is a new method for performing design cooling load calculations, derived from the heat balance method. It effectively replaces all other simplified (non-heat-balance) methods such as the cool#zg load temperature difference~solar cooling load~cooling load factor method (CLTD/SCL/CLF), the total equivalent temperature difference~time averaging method (TETD/TA), and the transfer[unction method (TFM). The radiant time series method relies on a 24-term response factor series to compute conductive heat gain, and it relies on a 24-term "radiant time series" to convert instantaneous radiant heat gain to cooling loads. This paper describes the radiant time series method and the generation of the response factors and the radiant time series coefficients and gives a brief comparison to the heat balance method.
