Phase change material (PCM) is introduced as a passive cooling unit for photovoltaic (PV) systems, which is critical to PV performance and durability. Melting point and latent heat capacity become the most important factors for choosing the optimal PCM for this purpose. One technique to examine the behaviour and attributes of PCMs for validation purposes is to use T-History. The thermophysical properties determination through the cooling phase behaviour of the PCM are the main areas of investigation in this study and highlight its potential. For this investigation, commercial available PCM 2245 has been chosen. Its melting point, specific heat capacity for solid and liquid, and latent heat capacity are ascertained by the application of mathematical data analysis. The results show that the melting point is obtained at 43.29 °C (316.44 K), the specific heat capacity is 3.71 kJ/kg K (liquid) and 27.9 kJ/kg K (solid), and latent heat energy is 118.71 kJ/kg. This PCM has quite a good potential for the application of PV cooling systems especially in Malaysia climate.

摘要

Phase change material (PCM) is introduced as a passive cooling unit for photovoltaic (PV) systems, which is critical to PV performance and durability. Melting point and latent heat capacity become the most important factors for choosing the optimal PCM for this purpose. One technique to examine the behaviour and attributes of PCMs for validation purposes is to use T-History. The thermophysical properties determination through the cooling phase behaviour of the PCM are the main areas of investigation in this study and highlight its potential. For this investigation, commercial available PCM 2245 has been chosen. Its melting point, specific heat capacity for solid and liquid, and latent heat capacity are ascertained by the application of mathematical data analysis. The results show that the melting point is obtained at 43.29 °C (316.44 K), the specific heat capacity is 3.71 kJ/kg K (liquid) and 27.9 kJ/kg K (solid), and latent heat energy is 118.71 kJ/kg. This PCM has quite a good potential for the application of PV cooling systems especially in Malaysia climate.
