The effects of fresh air ratio of a constant air volume air conditioning system on thermal comfort levels inside a large hall

The government building energy consumption in the Federal Territory of Putrajaya continues to increase in line with its development day by day. Several control parameters and specifications have been set in the daily operation of government office buildings especially the guidelines set by the Publi...

Civil engineering (General) The government building energy consumption in the Federal Territory of Putrajaya continues to increase in line with its development day by day. Several control parameters and specifications have been set in the daily operation of government office buildings especially the guidelines set by the Public Works Department (JKR). However, JKR does not have thermal comfort standards made especially for non-office government buildings, especially government buildings that have been operating for more than 10 years. Various failures have occurred to the air conditioning system and equipment in the building which affects the thermal comfort. This field of study was conducted in the Plenary Hall, Putrajaya International Convention Centre (PICC) to identify thermal comfort. Experimental study of thermal comfort is done in current condition and after the repair is done. Each condition will be tested base on two loads through zoning during normal weather conditions. The two conditions were observed through load condition measurements and three different fresh air ratios using direct reading instruments. This study is focused on improving the capacity of the hall air conditioning system based on the existing standards by operating the ratio of fresh air, indoor temperature and even relative humidity which will be used as an indicator for air quality and indoor air comfort level. The results of this study shown that the comfort level of the occupants decreased while the indoor space temperature increased which eventually this research focused on optimized comfort parameters for the ratio of fresh air supply in the comfortable indoor space of the large hall. This paper contained experimental analysis and thermal comfort index calculation. 2021 Thesis http://eprints.utm.my/id/eprint/102100/ http://eprints.utm.my/id/eprint/102100/1/ALAzharinoAhmadMSKA2021.pdf application/pdf en public http://dms.library.utm.my:8080/vital/access/manager/Repository/vital:145657 masters Universiti Teknologi Malaysia, Faculty of Engineering - School of Civil Engineering Faculty of Engineering - School of Civil Engineering
