BASICS OF THERMAL ENERGY STORAGE BASICS OF THERMAL ENERGY STORAGE

WHY STORE ENERGY ? l to size a chiller to satisfy the average load WHY STORE ENERGY ? l to size a chiller to satisfy the average load instead of the maximum load (few hours per day or even per year) ñ the chiller runs on a continuous basis l to increase plant capacity l to increase system reliability (back-up) l to increase system efficiency (no short cycle) l to protect the environment : – reduce CO 2 emissions – limit the use of CFC's or HCFC's l for energy management (off-peak electricity period) l to reduce system operating costs

TRADITIONAL SOLUTION STL SOLUTION Reduced Installed Capacity TRADITIONAL SOLUTION STL SOLUTION Reduced Installed Capacity

Energy management by CRISTOPIA Thermal Energy Storage l Reduce – – – – l Energy management by CRISTOPIA Thermal Energy Storage l Reduce – – – – l chiller size by 30 to 70% use of refrigerant by 50 to 80% cooling tower installation space for plant maintenance running cost CO 2 emissions Increase – cooling capacity from existing chiller – plant utilization – equipment life l Additional benefits – avail yourself to a back-up system – shift cooling load from peak hours to off-peak period
