Implementation of the revised Transfer Function Method and evaluation of the CLTD/SCL/CLF Method

Castelino, Richard Lawrence
A professional software program, currently called ~V AC, was developed in order to calculate the cooling loads for a building based on the revised Transfer Function Method. This program, written in the C-programming language, executes under Microsoft WINDOWSTM as a user-interactive, menu driven program. In addition to cooling load calculations, the program also performs calculations of the heat extractionrates for desired zones~ and the heating load for the building based upon steady state heat transfer.The results of the CLTD/SCL/CLF Method for three test zones and other test cases of externally shaded glass areas were compared with those of the revised Transfer Function Method. Differences in the implementation and calculation methodology of the methods were pointed out and the results discussed.
