District Cooling via 30000kWh IceBat Cold Battery System

Application                                                                          

A nominal capacity 30,000kWh IceBat Cold Battery Thermal Energy Storage System has been successfully operating within one of Europe’s largest District Cooling applications providing critical cooling to commercial facilities and data centres within the business area of Paris.

This installation, within the important large capacity primary cooling sector, provides a large scale and efficient Cold Battery System to deliver mutli megawatt primary cooling capacity for a business district in Paris.

Continuous uninterruptible cooling is clearly essential for data centre and critical IT operations with this application providing a great example of a well proven large scale high performing primary cooling system with Cold Battery Technology at its heart.

The IceBat system is charged via glycol chillers, operating with low-cost tariff input electricity, to maintain cooling capacity in order to satisfy peak daytime demand periods.

PURE EFFICIENCY | PURE SUSTAINABILITY | PURE SAVINGS

Importantly with a system such as this the same glycol chillers that are used to charge the IceBat system can also be configured to deliver primary cooling operating alongside the IceBat Cold Battery system in parallel configuration, hence increasing the amount of cooling capacity available.

This provides greater cooling capacity during peak demand periods, with IceBat + Chillers, which maximises the utilisation and effectiveness of both the IceBat Cold Battery and the chillers/charging plant.

Equipment Schedule

  • IceBat storage system model: ICEBAT UW
  • IceBat Cold Battery capacity: 30,000 kWh (30 megawatts)

Summary

This application is a great example of a demanding project where the security of supply is greatly improved by the IceBat Cold Battery design, this is especially beneficial where critical continuous uninterrupted cooling is required 24/7.

A conventional ‘mechanical cooling plant only’ method of delivering cooling would have required much larger chiller/cooling plant, and associated electrical supplies, in order to meet the peak cooling demand.

Equally important with this configuration, as delivering large capacity muti megawatt cooling batteries, is the more efficient operation of the chiller/cooling plant that is achieved during colder overnight charging periods where additional cost & carbon savings are delivered.

In summary this proven application demonstrates that multi megawatt primary cooling capacity can be delivered with IceBat Cold Batteries whilst also delivering significant energy cost & carbon savings.
