As the name suggests, they use ice to build and store cooling when cooling demand and/or energy rates are low (mostly overnight), which the system then uses for process cooling purposes or air-conditioning when energy rates are high (mostly daytime).

Benefits

• Refrigeration systems up to 50% more compact.
• Operational cost savings: ice formed overnight with cheaper electricity.
• 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.
• Ideal for applications where there are large fluctuations in cooling demand e.g. milk intake / pasteurisation in Dairy Facilities.

Applications

Ice thermal storage is typically used for

• Dairies
• Breweries
• Process Cooling Applications
• Immersion Cooling
• Wet Air Cooling Systems for Fruit & vegetables
• Air conditioning
• District cooling
• Emergency cooling
