Abstract

Nowadays, human comfort and thermal comfort in buildings is a very major concern in the use of air conditioning systems. We usually encounter in which human comfort and heat not be achieved on a number of factors. This is likely because the cooling air distribution system from AHU to the occupied zone, fail to control moisture and leaks at the design air volume flow. Therefore, this study aims to determine the correct location and orientation of the branches required in the duct AHU related systems using Hydronic Radiant Cooling (HRC) System. Using hydronic radiant cooling (HRC) system we are able to minimize risks to humans and the environment from dangerous substances contained in other coolants. The study was conducted using three types of studies for each branch and orientation, of the use of water, water with ice, and water with ice and salt. The results of three studies, the temperature at the first branch using water with ice and salt most cold compared with other branches at the top of 20.2°C. However, the temperature of the third branches is more suitable to achieve thermal comfort in Malaysia of 23.2 ° C within the range of thermal comfort of 23°C to 26°C. In conclusion, the results of this study showed that the temperature in the third branch more suitable for residents in Malaysia. While the appropriate orientation in the system is at the top because the air circulation at the top is better than bottom, left and right to reach the thermal comfort in Malaysia.
