Building-integrated PCM-TES for peak load reduction

Vasken Dermardiros, Andreas Athienitis

Abstract: The objective of this paper is to study, through simulation, the impact of an active Phase-Change Material based Thermal Energy Storage (PCM-TES) system on the peak heating demand during a winter morning start-up for a low thermal mass office. The PCM-TES intended for building integration consists of PCM panels with active air circulation between the panels. Air is drawn through multiple channels to charge and discharge the PCM enabling the system to be used for both heating and cooling purposes – conditioned air, room air or outdoor air for night cooling can be utilized. Model-based control strategies are employed for better latent heat utilization and improved system integration. Results showing the reduction of the peak electric demand are presented for varying amounts of PCM and for different HVAC activation times.
