Cooling Load Investigation for Air-condition System in Faculty of Education and Technical Vocational, UTHM

Abstract

When it comes to designing an air conditioning system prior to installation, cooling load estimation is required. This is because the proper design of an air conditioning system can provide thermal comfort to occupants in the building, significantly affects the overall energy consumption and reduces maintenance costs of the air conditioning system. In FPTV (Block C & D), UTHM, the current air conditioning system has been operating for some time. It is not known whether the current air conditioning system in the studied buildings is still working efficiently as before. The objective of this study is to determine the efficiency of the air conditioning system in FPTV (Block C & D), UTHM. The study is focused on non-residential building. In this study, cooling load estimation is carried out using the Cooling Load Temperature/Cooling Load Factor/Solar Cooling Load Factor (CLTD/CLF/SCL) method. Prior to the cooling load estimation, the data of the studied buildings are gathered from physical measurements, calculations, floor plan drawings and many more. The total cooling load obtained is compared to the chiller’s cooling capacity. From the comparison, it is observed that the calculated total cooling load of the studied buildings is within the chiller’s cooling capacity. In conclusion, the efficiency of air conditioning system in FPTV (Block C & D), UTHM has been determined. It is proven to be still efficient and needs no replacement now. The scopes of research can be extended on the study of air circulation and heat distribution in conditioned spaces using simulation software, and on the study of indoor air quality.
