Potential benefits from Thermosyphon-PCM (TP) integrated de- sign for buildings applications in Toronto

The integration of phase change material (PCM) and thermosyphon is introduced as a mean to transfer solar radiation into the indoor air. A steady state, one dimensional model is analysed here to investigate the potential benefits of the TP. Analysis of the power transferred by the thermosyphon-PCM panel shows that more than one mega-watt-hour per square meter (MWh/m 2 ) energy can be transferred into buildings in Toronto annually. Therefore, by mounting TP, which has thermal resistance on an order of -4 K/W, solar energy can be a source of heating for buildings. In the coldest month of the year, January, the insolated surface of the TP can reach as high as 54.5℃.
