How to dissipate heat through energy storage air cooling

Does cool storage reduce energy consumption?

Cool storage will reduce the average cost of energy consumed and can potentially reduce the energy consumption and initial capital cost of a cooling system compared to a conventional cooling system without cool storage.

What is thermal energy storage for space cooling?

Thermal Energy Storage (TES) for space cooling, also known as cool storage, chill storage, or cool thermal storage, is a cost saving technique for allowing energy-intensive, electrically driven cooling equipment to be predominantly operated during off-peak hours when electricity rates are lower.

What is a cool storage system?

Cool storage systems are inherently more complicated than non-storage systems and extra time will be required to determine the optimum system for a given application. In conventional air conditioning system design, cooling loads are measured in terms of "Tons of Refrigeration" (or kW’s) required, or more simply "Tons”.

Why is a cool storage system so expensive?

The cooling load is too small to justify the expense of a storage system. Typically, a peak load of 100 tons or more has been necessary for cool storage to be feasible. The design team lacks experience or funding to conduct a thorough design process.

How does ice storage work?

The ice storage system handles the balance of the cooling requirement. In a 400-ton peak cooling load system, ice storage reduces the nominal capacity of the chiller and cooling tower from 400 tons to 200 tons with associated savings of $73,500 by allowing users to take advantage of the low temperatures available with ice.

How do you choose a chiller for ice storage?

For chilled water or ice storage systems, designers select chillers based on the “Ton-hours” of cooling required. A theoretical cooling load of 100 tons maintained for 10 hours corresponds to 1000 ton-hour cooling load. One of the design challenges of thermal storage is to develop an accurate cooling load profile of the project.
