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.

Does a building air conditioning system work at 100% capacity?

Realistically, no building air conditioning system operates at 100% capacity for the entire daily cooling cycle. Air conditioning loads peak in the afternoon -- generally from 2 to 4 PM -- when ambient temperatures are highest, which put an increased demand for cooling and electricity.

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”.

Should a 50 ton chiller be specified for a conventional HVAC system?

For a conventional HVAC system, a 100-ton chiller must be specified to account for the peak demand, however, with the TES design depending upon the operating strategies a 50-ton chiller with 50% storage option shall provide the same results and meet the peak load requirements.

How much energy does a chiller system save?

For example, with lower hp of smaller pumps, fans, cooling tower and chiller result in as much as a 25% increase in operating energy savings over a traditional chiller system. The air-handling unit fans accounts for significant operating energy to the tune of 30 to 50%.
