Thermal Energy Storage System

Thermal Energy Storage System (CWTES). This system utilizes only the sensible heat of water for cooling energy storage in a chilled water storage tank and discharges the stored coldness for air-conditioning during the on-peak time.

The key technology of CWStorage system is the diffuser design which ensures thermal stratification of chilled water and warm water by density difference. FTEnE’s technology is the state of the art technology which is recommended in ASHRAE’s design guide. They have a long history of installation around the world including U.S.A., Japan, Korea and middle-east Asia.

Some key features of Chilled Water-Thermal Energy Storage Cooling:

Lowest initial investment cost

30-40% energy saving by utilizing conventional chillers whose

Efficiency is higher than low temperature chillers

Simple system with easy controls without additional heat

Light in weight compared to Si-Br.

Exchangers and less equipment

Efficiency of discharging coldness is very high

Easy to convert conventional system into CWTES system by

Adding only chilled water storage tank

Convertible to heating purposes

Environmentally friendly system free from brine

Storage water can be utilized for fire-fighting in emergency
