Which cooling system is a good application for thermal ice storage?

Any chilled water cooling system may be a good application for thermal ice storage. The system operation and components are similar to a conventional chilled water system. The main difference is that thermal ice storage systems are designed with the ability to manage energy use based on the time-of-day rather than the cooling requirements.

What temperature should ice water supply fluid be?

The supply cooling fluid for external melt systems may be 34°F (1.11°C) if ice water is used directly or 36°F (2.22°C) if an ice water heat exchanger is used in the district plant. The supply fluid for internal melt systems can be as low as 37.4°F (3°C) to the district cooling heat exchanger. 7. Storage Containers:

What are the integration requirements for cool storage systems?

The specific integration requirements vary for the different types of cool stor-age systems. In some cases, multiple integration options exist for a single type of cool storage system. Fundamen-tally, the storage device separates the generation of chilled coolant from its delivery to air handling units.

What temperature does a water chiller store water?

Chilled water systems typically store supply water at 39°F to 42°F, which is compatible with most water chillers and distribution systems. Return temperatures are typically in the range of 55°F to 60°F or higher. Stratified low-temperature-fluid TES systems operate similarly but with lower supply temperatures, typically between 29°F and 36°F.

What is a distribution cooling pipe?

The distribution cooling pipes are typically sized for a delta-T of 20°F (11.1°C). This reduces the chilled water flow volume, thus enabling the use of smaller pipes and pumps. The ice storage provides the energy management ability to shift energy use to lower cost periods of time.

What temperature is chilled water supplied to air-handling units?

Chilled water is typically sup-plied to air-handling units at 44°F (6.7°C). An ice plant can provide chilled water temperatures at nominal 32°F to 36°F (0 to 2.2°C), and its larger Delta T is wasted.
