Fellow ASHRAE ABSTRACT The radiant time series method is a new method for per-forming design cooling load calculations, derived from the heat balance method. Notes the introduction of a new factor, the solar cooling load (SCL). Related titles. Specific information on the contents of each addendum ... ASHRAE. ashrae cltd tables mental life de. In addition to tables published by ASHRAE for select latitudes, a computer program called CLTDTAB, available since 1993, can be used to generate custom CLTD/CLF/SCL tables for a specific zone type for any latitude and month. Table 7 lists some values for laboratory equipment, but, as is the case for medical equipment, it is for general guidance only. (The CLTD tables are based on this condition.
