Energy storage power station needs air conditioning

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”.

How many tons of air-conditioning does a building need?

For a building demanding 400 tons of air-conditioning, the advantages are exemplified by the installations below. A traditional chilled water system using 44°F (6.7°C) supply and 54°F (12.2°C) return will require 2.4 gallons per minute (GPM) of chilled water for each ton-hour of refrigeration.

Does air-conditioning affect power plant load profile?

It has been seen that the air-conditioning cooling loads drives peak electric power demand. The air-conditioning accounts for almost 40% electricity consumption in US and as more and more building’s square feet and air-conditioned facilities are added up it has a definite impact upstream on the power plant load profile.
