Cooling down energy storage equipment

What is thermal energy storage?

Energy storage has become an important part of renewable energy technology systems. Thermal energy storage (TES) is a technology that stocks thermal energy by heating or cooling a storage medium so that the stored energy can be used at a later time for heating and cooling applications and power generation.

What is cool thermal energy storage (CTEs)?

Cool thermal energy storage (CTES) has recently attracted interest for its industrial refrigeration applications, such as process cooling, food preservation, and building air-conditioning systems. PCMs and their thermal properties suitable for air-conditioning applications can be found in .

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 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”.

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.

How does thermal ice storage benefit a district cooling plant?

District cooling plants utilizing thermal ice storage provide both first cost and energy cost savings. 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.
