PCM Thermal Storage System Analysis Using EnergyPlus and BCVTB

Aidan Jones, Donal Finn

Abstract: This paper presents the implementation of a phase change material thermal storage unit in EnergyPlus and an analysis of the energy cost of its use in a retrofit application. A significant portion of the daily electrical heating load can be shifted from on-peak to off-peak times if flexibility is brought to heating loads by methods such as thermal storage. In this paper it is seen that use of the thermal storage system increases overall electrical use over the course of a 24 hour period. A time of use price incentive or tariff dependent on load management would be necessary to facilitate the adoption of such demand side management technology. The analysis is performed using a comprehensive phase change material thermal storage model, developed using Matlab, which is validated in this paper. This model is incorporated into the EnergyPlus environment through the Building Controls Virtual Test Bed. The rest of the plant is modelled in EnergyPlus, using equipment specifications from a retrofit application of an office building.
