Use of thermally activated ceiling panels with PCM for building thermal mass enhancement and peak load management.

Summary

Ceiling mounted radiant cooling panels with PCM are an alternative TABS system for lightweight buildings and retrofitting, where the PCM gives the necessary thermal mass, while the hydronic tubes provide active charging and discharging of the PCM. In the present work the performance, in relation to thermal comfort and energy storage, of PCM radiant panels is evaluated through computer simulations using TRNSYS 17, for a 2-persons office in a lightweight office building. Results from the study show that the main challenge during system design is to determine the optimum phase change temperature range of the PCM material, so that when actively charged/discharged by the embedded pipes system, the ceiling panels will prove efficient in matching thermal energy availability and demand and in keeping the desired indoor operative temperature.
