PHASE CHANGE MATERIAL COOLING IN EQUIPMENT ROOM
The best way to cool an equipment room is using free air, and but when the outside temperature goes over the required temperature, then use the Phase Chance Material to cool the required load (for example the IT Load). It’s quite easy to install Phase Change Material with very low energy-costs.
The first Phase Change Material design, for the use of energy storage, dates back to the end of the 19th century. Then they used packaged ice to keep products longer. Tizzin has succeeded in developing Phase Change Material in a smart way since 2010, making it possible to cool equipment room and to reduce the electric consumption extremely. This results in a high energy saving and very low CO2 emissions.
PHASE CHANGE MATERIAL COOLING MATERIAL
Phase Change Material cooling material is based on inorganic incombustible salts and is none toxic.
THE THERMAL BATTERY
Heat storage in Phase Change Material can best be compared to an electric battery or better as a "thermal battery". You can charge the battery with heat (in day time) and discharge this heat at a later stage (during the night). For example, we can charge the Phase Change Material at night time with cold air and release this cold storage during the day.
HOW DOES THAT WORK?
During outside air temperatures between 18°C and 25°C, cooling is normally provided by outside air but when the outside temperatures rise the Phase Change Material will melt as soon the outside air temperature rises above the melting temperature. This absorbs the hot energy and cool down the air within the ASHRAE range. Once the temperature of the outside air drops, the process is reversed. The Phase Change Material solidifies overnight because the temperature of the outside air drops below the solidification temperature. This process can repeat itself indefinitely.
