| Summary: | The one of the most important part of a solar collector system is the solar tank. The relevant type and capacity of the solar tank is a requirement of the good operation of the system. A solar tank particularly filled with phase change material has smaller dimensions and bigger heat capacity than the conventional tanks. The main problem of the operating of the PCM tanks is the low coefficient of thermal conductivity of the phase change material. During the discharging of the tank the PCM solidifies to the inner surface of the tube. The thermal flux will be decreased by the thermal insulating effect of the thicker and thicker solid PCM layer. We have calculated the time of the phase changing and the operating temperature of the heat accumulating. If the temperature is lower than the conventional tanks it could result a higher efficiency of the solar collector system. We have made pre-calculations to study this possibility. |
