| Due to modern architectural trends highly glazed surfaces and lightweight materials are widely used in new buildings. This brings them out to have a lack of thermal inertia and couldleadto high cooling and heating loads. Phase change materials (PCMs) are able to provide effective thermal mass to this kind of buildings enhancing their thermal properties. Nevertheless, prior to the building construction process, the designer needs to compute the effect of the PCM over the energy consumption of the building and the occupant comfort. For the purpose of achieving this, a new PCM Type for TRNSYS 17 simulation software has been designed. This new PCM-Type is able to model a wall with a PCM layer inside, which can be located in any place within the wall, and includes the possibility to simulate active systems, based on both capillary pipes and TABS, in the modelled walls. The developed PCM-Type uses a temperature dependent heat capacity approach which takes into account the hysteresis phenomena. A comparison between the new developed PCM-Type and other existing TRNSYS Types is carried through. | |
