Abstract
En 中文
Cooling load calculations are essential in sizing air conditioning equipment. The transfer function method (TFM), which is well-known and adopted by ASHRAE, was programmed in this work to predict the hourly cooling load due to different types of wall, roof and fenestration. The developed computer code was tested against hand calculations and was found to be accurate. When comparison was done with ASHRAE examples, some differences were noticed in the cases of cooling load due to wall and roof. In other cases, the agreement was perfect. The disagreement with ASHRAE results was pin-pointed, and a revision of the ASHRAE example was made. The outputs of the program were also compared with the well-known Carrier program, and the agreement was satisfactory. Various runs were made, and the results of these runs are discussed. The effect of changing the wall color on cooling load and on sol-air temperature is studied. Copyright (C) 1996 Elsevier Science Ltd
