Air conditioning system consumes 40-60 percent of the total consumption of residential buildings in Thailand. Therefore, the accurate cooling load calculation can result in efficient energy conservation and the selection of a suitable air conditioning system for the cooling load which can reduce the cost in the part of the air conditioning system as well. In Thailand, CLTD/CLF method is popular because it can be easy to understand in addition fast to calculate the cooling load without having to use a complex computer program, however the results will be less accurate. The purpose of this article is to study of cooling load calculation error by CLTD/CLF method compared to simulation with DOE2.1E
The results of the study of the cooling load calculation error from the wall group selection by CLTD/CLF method comparing between the selecting wall group (Group F) and the neighboring wall group (Group E and Group G), it was found that there is 4.31% error between Group E and Group F, 6.77% error between Group G and Group F and both neighboring wall groups’ average is 5.54%error from the selecting wall group. And the results of the study of cooling load calculation error by CLTD/CLF method compared to simulation with DOE2.1E ver.121 found that the calculation of the CLTD/CLF method with the CLTD values from the selecting wall (Group F) were compared to simulation with DOE2.1E ver.121 has 0.72% error and the calculation of the CLTD/CLF method with the CLTD values from the neighboring wall (Group E and Group G) compared to simulation with DOE2.1E ver.121 has 3.55% error and 7.44% error respectively
