| Abstract | Most of Energy consumption in building ,normally. is from air conditioning. Air conditioning load depends directly upon heat gain into air-condition space. Heat gain into the room is one of largest part on air conditioning load This thesis. the compilation between light gain calculation algorithm and heat gain calculation algorithm to develop computer program had been done. In heat gain calculation part, this have been developed under concepts of finite different method. In this study. an attempt is made to verify a model of heat transfer through the wall by performing experiment on surface heat transfer. The model is investigated through calculation method by comparing with the results from measurement. The result from temperature comparison is satisfied with average percent of error around 26% for internal and external surface temperature. The results comparison for heat flux through wall have error around 3-7%. The results from light gain comparison is satisfied with average error around 10%. Heat gain comparison between five different wall types had been done in this thesis. The wall type having lowest heat gain into the room is wall with insulated material ( glass wool ) inside the wall layer and the wall having high heat flux is the first wall, cellocrete material , and the third wall , concrete block. Last part of this thesis is simulation of computer program to determine total heat gain into room with different scenarios. By vary type of wall and simulate for total heat gain into room using data from reference day in year 1996. |
