Impact of building-integrated PCM on the indoor thermal environment and energy performance of an office zone.

Number: pap. 0015

Summary

This paper investigates different design options for the integration of active Phase Change Material (PCM) in an office zone. The charging and discharging of the PCM, arranged in layers, is managed by a controlled airflow passing through these layers. Two configurations are considered: (a) PCM in a wall in which a PCM layer is in contact with the room air and; (b) PCM within a duct heat exchanger in a ceiling plenum. Several control strategies are also evaluated. In comparison with a room without PCM, it was found that the annual heating energy use can be reduced by 29% for the first configuration, and 33% for the second. An enhanced control strategy may yield a 38% reduction with the Configuration B. Furthermore, the morning peak load could be reduced by 22% by improving the charging/discharging strategy of the PCM in the ceiling plenum.
