Design of a Mini Thermal Storage System for Air- Conditioning Service

Thermal energy storage is a system that distributes chilled water or other media
to multiple buildings for air conditioning or other uses. Thermal Storage System
systems are useful for maximizing the thermal energy efficiency for meeting the
fluctuating cooling demands by shifting energy use from on peak to off-peak hours by
charging the Thermal Storage Tank during the off-peak hours and discharging it later
during the peak hour. For this reason, they are now receiving much attention among the
world. Due to that, this project aims to get initial understanding about thermal storage
system by design a mini thermal storage charging (during nighttime) and discharging
(during daytime) for air-conditioning system. This report discusses about the
background of this project regarding thermal storage operating strategy, system
operation and design of mini thermal storage system. The project is based on the
thermal storage system at Universiti Technologi PETRONAS's Gas District Cooling
but simpler and smaller. An analysis also was conducted on storage tank to characterize
the thermal storage tank.
