Numerical Investigation of the Integration of Phase Change Material on Solar Domestic Hot Water System
Solar collectors are commonly used for domestic hot water systems particularly in the regions where solar radiation is intense. However, the availability of hot water strongly depends on the availability of solar energy. Locating PCM-filled tubes in the hot water tank is an effective method for thermal energy storage since it utilizes the latent heat energy which has very high thermal capacity storage for a given volume. In this study, the melting and solidification process in a PCM tube is studied numerically using enthalpy-porosity technique. The numerical model developed in this work is based on a one-dimensional finite difference scheme in cylindrical coordinates, taking into account the radial temperature distribution in both phases. Simulations are performed for different water temperatures and water velocities in order to analyze the charging (melting) and discharging (solidification) process.
