Abstract

Nowadays, HVAC system is considered necessary towards today’s generation as everyone has the desired of living in comfort zone. The most important aspect influencing the HVAC system surely is the thermal comfort. Related to that, this study includes the analysis and the ways of identifying the current thermal comfort at the selected conditioned spaces which are several Bilik Kuliah at Floor 1 FKM building, UTeM. Basically, there are a few factors influencing the thermal comfort such as intrinsic factors and extrinsic factors. The intrinsic factors represent the internal factors such as metabolic rate, air velocity distributed, clothing, and the occupant’s activity inside the conditioned spaces selected meanwhile the extrinsic factors is the external factors like the sunlight, outside air temperature and outside relative humidity. There are 2 ways of determining the thermal comfort such as by using mathematical equation and by distributing a self-guided of questionnaires. Next, there will be a cooling loads calculation of the conditioned space to identify the real factors affecting the capacity calculated. Then, by using the cooling loads capacity result, it is necessary to identify is the usage of fan coil unit inside the bilik kuliah is helping enough to provide a thermal comfort to occupants. Finally, there will be some suggestion and recommendation on how to improve the current system to a better one in order to achieve the comfort zone.
