green cooling initiative: Best practice example

Process chillers, Centralised systems Product: Ice by night, air-conditioning by day: the TSU-C/D ice thermal storage

The TSU-C/D ice thermal storage unit by the Baltimore Aircoil Company (BAC) provides a constant near-freezing water (1-2 °C) supply for applications such as food processing, breweries and dairies at the lowest first cost.

The external melt system of the TSU-C/D unit stores cooling as ice when cooling demand and/or energy rates are low (mostly overnight), and releases cooling for air-conditioning when cooling demand and/or energy rates are high (usually daytime). As the TSU-C/D forms ice overnight when electricity costs are cheapest and condensing temperatures are lowest, operational costs as well as the carbon footprint are lowered.

As with all BAC cooling towers, the TSU-C/D model is independently certified by the Cooling Technology Institute (CTI), hereby ensuring that published thermal capacities reflect actual thermal performance. This eliminates the need for customers to perform costly individual cooling tower testing.
