A Model to Determine Thermal Performance of a Non-ventilated Double Glazing Unit with PCM and Experimental Validation

Phase change material (PCM) applied in the double glazing unit can decrease energy consumption and improve indoor thermal comfort by improving its thermal energy storage capacity. In the present work, a model to determine thermal performance of a non-ventilated double glazing unit with PCM and experimental validation was developed. The result shows that the developed model in present work can solve the coupled heat transfer problem between phase change and solar heat transfer in the double glazing unit filled with PCM.
