Abstract

Building Sector is the major electricity consumer and its costly to building owners. Therefore the application of thermal energy storage (TES) has gained popularity to reduce energy cost. Many attractive tariff packages are being offered by the electricity provider to promote TES. The tariff packages offered higher cost of electricity during peak period and lower cost of electricity during off peak period. This paper presented the opportunity to implement a centralized air-conditioning plant integrated with thermal energy storage with partial operation strategies. Building load profile will be calculated hourly according to building specification and building usage trend. TES operation conditions will be designed according to building load demand profile, storage capacity, tariff packages and peak/off peak period. There is an opportunity of energy cost reduction when TES’s chillier is in operation during off peak period. In conclusion, there are opportunities of energy cost reduction by partially operation of centralized airconditioning plant integrated with thermal energy storage.
