WHY STORE ENERGY ?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

CRISTOPIACRISTOPIA Thermal Energy Storage 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
