Description

Space cooling places a significant peak load on the electrical grid during hot, sunny afternoons. With the introduction of time-of-use billing, space cooling during these periods has become very expensive. To reduce utility costs and shift peak loads, the use of a medium temperature chiller coupled with a sensible cold thermal storage system was investigated. Optimal configurations were found for seven cities located within each of the seven ASHRAE climate zones and an analysis on the energy consumption and annual utility costs are presented. It was found that in all locations, peak loads from air-conditioning could be reduced or eliminated, and that when the cooling load was great enough, or the peak utility rate was sufficiently greater than the off-peak period, annual utility costs savings, approaching 30% in some areas, could be realized.

Offsetting Peak Residential Cooling Loads Using a Medium Temperature Chiller and Sensible Cold Thermal Storage

Syracuse, NY
