An advanced thermal storage system for heating and cooling buildings.

Author(s) : STRITIH U.

Summary

The paper presents a cheap thermal storage system using paraffin wax as the thermal storage medium, with an ordinary air/water heat exchanger to store and utilize the heat or cold. The fins that usually increase the surface area of the heat exchangers were used to enhance the heat transfer in the paraffin. The experimental results are based on the charging and discharging of the thermal storage for specified volume flows. Temperature variations for the inlet and outlet water versus time as well as paraffin-wax temperatures are presented for the charging and discharging. The energy fluxes for latent and sensible systems are also presented and compared. The conclusion of the article explains whether this type of thermal storage can be used for heat or cold storage in a house, i.e. if it can store enough energy, and if charging and discharging times are suitable.
