摘要：
Structural insulated panels (SIPs) outfitted with phase change materials (PCMs) are high thermal performance envelope components because they combine the high insulation properties of SIPs with the thermal storage properties of PCMs. The integrated system is known as PCMSIP (Medina a al., 2008). The main objective of this research was to develop an optimal PCMSIP based on SIP core materials, PCM encapsulating materials, and configurations (horizontal vs. vertical) of the encapsulating elements. A dynamic wall simulator was used for the experimental testing. The results showed that heat fluxes through the SIPs were reduced when the SIPs were made using urethane core as opposed to expanded polystyrene (EPS) core. In general, SIPs outfitted with PCM showed lower peak heat fluxes when compared to identical SIPs but without PCM. PVC as an encapsulating material was the least effective material for this purpose and the configuration of the encapsulating elements mattered. The horizontal configuration showed to be more effective in reducing peak heat fluxes through the SIPs.
