Peak load shaving by indirect evaporative cooling (IEC), Thermal Energy Storage (TES) and a combination of both.

Summary

The increasing technical and comfort cooling demand in office buildings leads to high peak demands. A well-known method of reducing peak production capacity, that has not penetrated the building industry, is the use of thermal storage. In this paper it will be shown that in a 17 000 m2 office building, located in Belgrade, with a nominal comfort cooling demand of 1 565 kW, the application of indirect evaporative cooling of the ventilation air will reduce the peak demand by approx. 905 kW to 660 kW, a reduction of 58%. Combining this with a thermal storage capacity of 1 810 kWh, will lead to a further reduction in necessary chiller capacity to approx. 495 kW or 32% of the original demand.
