Abstract
The heat generated within a closed space like office has increased drastically in recent years with the optimal use of the heat generated equipment such as computer, and other machines. As air conditioning is an inherently energy intensive process, so there is a need for devising more efficient system that would consume less energy while maintaining very comfortable condition for occupants inside. The desiccant air conditioning combined with chilled ceiling is a new concept of air conditioning system. This technique had been widely used in a number of European countries, however, similar the use of such system has not been reported to date in any humid tropical countries. With the aim of investigating the feasibility of such a system in Malaysian context, a climate chamber [4.25 m (L) ×3.75 m (W) × 2.7 m (H)] has been built in the Fluid Dynamic Laboratory of the Universiti Sains Malaysia wherein a desiccant dehumidifier combined with a chilled ceiling system has been installed. The system uses 100% ventilation air to maintain the freshness of air inside the chamber. The study aims at evaluating the relative performance of the above-mentioned hybrid system compared to conventional air conditioning system. The specific focus is in measuring energy consumption of the whole system. 4 experiments were conducted during the study with simulated heat loads of 0 W/m2, 25 W/m2, 62 W/m2 and 100 W/m2. The initial results show that such system is viable in Malaysia with the possibility of reduction of energy to the tune of 40% compared to the conventional system. However, more studies need to be conducted prior to large scale use.
