6 FAQs about [Calculation of coolant usage in energy storage system]
How are cooling loads measured?
In conventional air conditioning system design, cooling loads are measured in terms of "Tons of Refrigeration" (or kW’s) required, or more simply "Tons”. For chilled water or ice storage systems, designers select chillers based on the “Ton-hours” of cooling required.
What is space cooling load?
Space (zone) cooling load is used to calculate the supply volume flow rate and to determine the size of the air system, ducts, terminals, and diffusers. The coil load is used to determine the size of the cooling coil and the refrigeration system. Space cooling load is a component of the cooling coil load.
How do you calculate a cooling coil load?
The additional cooling coil load is calculated as follows: CFM = Ventilation airflow rate. Unless the return ductwork system is extensive and uninsulated or passes over a non-conditioned space, only the heat gained by the duct supply system is significant.
How do you calculate a ton of cooling?
Even the definition of a ton of cooling is derived using ice. The latent heat of fusion (phase change of water to ice or ice to water) is 144 Btu’s per pound of water. One ton of ice is 2,000 pounds, Therefore, the energy required to change 2,000 pounds of water to ice would be 144Btu/lb. x 2000 lb. = 288,000 Btu’s.
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.
Can a thermal storage system track rapid cooling load fluctuations?
The thermal storage system may not be able to track rapid cooling load fluctuations. HVAC cooling applications such as office buildings, schools, hospitals, retail stores, etc. where cooling requirements are relatively constant over a minimum 6-hour period and operating control systems should be very simple.
