BASICS OFTHERMAL 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

Energy managementbyCRISTOPIA 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
