Utilizing Energy Piles as Cold Storages

Abstract

Energy piles are load-bearing structures that can be utilized as a part of thermal storage. They are used both storing and collecting phases of storage operations. These piles have been recently used in underground parking hall in Turku, Finland. The thermal energy stored is obtained from solar collectors. Energy pile systems have been, however, for storing and utilizing heat. Demand for cool has increased in recent years due to heat waves and living comfort. There is also a need to reduce fossil fuels usage for cool or cold production. Thus, the goal of this paper is to study utilization of energy piles for cold storages integrated with renewable sources.
