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).
- 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.
Ice thermal storage is typically used for
- Process Cooling Applications
- Immersion Cooling
- Wet Air Cooling Systems for Fruit & vegetables
- Air conditioning
- District cooling
- Emergency cooling
