4. BASICS OF THERMAL ENERGY STORAGE

5. WHY STORE ENERGY ?
to size a chiller to satisfy the average load instead of the maximum load (few hours per day or even per year)
the chiller runs on a continuous basis
to increase plant capacity
to increase system reliability (back-up)
to increase system efficiency (no short cycle)
to protect the environment :
reduce CO2 emissions
limit the use of CFC's or HCFC's
for energy management (off-peak electricity period)
to reduce system operating costs

6. Reduced Installed Capacity
TRADITIONAL SOLUTION
STL SOLUTION
Reduced Installed Capacity

7. Energy management by CRISTOPIA Thermal Energy Storage
Reduce
chiller size by 30 to 70%
use of refrigerant by 50 to 80%
cooling tower installation
space for plant
maintenance
running cost
CO2 emissions
Increase
cooling capacity from existing chiller
plant utilization
equipment life
Additional benefits
avail yourself to a back-up system
shift cooling load from peak hours to off-peak period
