This technology was specially created in 1982 for the air conditioning and industrial refrigeration of commercial and business sectors and consists of shifting electricity consumption from peak hours to off-peak hours and reducing the installed electrical capacity.
Most air conditioning and refrigeration systems are sized to meet the maximum level of demand, even if these peak periods are only short-lived. Moreover, peak demands on cooling last only a few days per year and vary greatly over the course of the same day.
Thermal energy storage makes it possible to adjust peaks in demand. Energy is stored during off-peak periods and transferred for use when demand exceeds the installed cooling capacity.
Not only does this technology make it possible to cut electricity costs, it is also more environmentally-friendly:
Air conditioning for the commercial sector: supermarkets, airports, cinemas, etc.
Refrigeration: pharmaceutical industry, abattoirs, ice skating rinks, etc.
