About Cristopia

Thermal energy storage

Use:

CRISTOPIA STL (Storage of Latent heat) technology is widely used in Europe, Asia and North America. It consists of nodules used to store the cooling energy produced by water chillers.

The energy is primarily stored at night-time, when cooling demand is lower, and redelivered during the day when greater cooling capacity is needed.

Furthermore, due to the lower temperatures when energy is stored at night, the chillers operate more efficiently. Demand on the chillers is thus better balanced between day and night, which enables the use of smaller units.

STL storage features a special control and supervision system, which controls and monitors the system’s performance.

Advantages

Reduce

  • chiller size by 30% to 70%
  • the quantity of coolant
  • the size of cooling towers or dry coolers
  • the subscribed demand
  • the floor area of technical rooms
  • chiller shutdown/restarts
  • maintenance costs
  • running costs

Increase

  • the cooling capacity of your system
  • the energy efficiency of the chiller
  • the consistency of the electrical load profile
  • system yield and dependability
  • system service life
  • system flexibility
  • energy management

Enhance the environmental footprint

  • better energy management
  • smoother electrical inrush current, favouring more efficient electrical power stations
  • reduced primary energy consumption (TEP)
  • reduced CO2emissions
  • reduced peak-time strain on electrical distribution networks (Controlled Electrical Demand)
  • reduced coolant quantities
  • 20% to 40% improvement of TEWI*

* The TEWI (Total Equivalent Warning Impact) of a chiller facility is defined as the total direct impact of coolant gas emissions (leaks and losses at end of life) and the indirect impact of CO2 emissions (due to primary energy consumption for cooling).
