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”.
How does liquid air energy storage work?
Liquid Air Energy Storage (LAES) applies electricity to cool air until it liquefies, then stores the liquid air in a tank. The liquid air is then returned to a gaseous state (either by exposure to ambient air or by using waste heat from an industrial process), and the gas is used to turn a turbine and generate electricity.
How efficient is compressed air energy storage?
Compressed air energy storage has a roundtrip efficiency of around 40 percent (commercialized and realized) to about 70 percent (still at the theoretical stage). Because of the low efficiency of the air liquefaction process, LAES has a low roundtrip efficiency of around (50–60%).
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 are the different types of cool storage systems?
There are many different types of cool storage systems representing different combinations of storage media, charging mechanisms, and discharging mechanisms. The basic media options are chilled water, ice, and eutectic salts.
