Principles of Ice Thermal Storage

Ice Thermal Storage as the name suggests, creates ice to build and store cooling when cooling demand and/or energy tariffs are low (normally overnight). The system then uses this for air-conditioning or process purposes when energy tariffs are high (normally daytime).

Benefits of Ice Thermal Storage

  • Refrigeration systems up to 50% more compact

  • Operational cost savings: take advantage of cheaper energy tariffs

  • Lower energy consumption basing the cooling system on average conditions rather than peak reduces power requirements and the refrigerant charge

  • Reduced carbon footprint: most of the cooling occurs overnight when condensing temperatures are lower and the cooling system requires less energy

  • Less compressor maintenance since the compressor operates continuously at full capacity and not under fluctuating partial load

  • Thermal storage systems provide back-up cooling
