This work is to investigate and validate of solar thermal storage system integrated with phase change material (PCM). The existing system is suggested to setup a Storage tank with phase change material (PCM), between the Solar concentrate dishes and Vapour absorption machine (VAM). The storage tank was used instead of an Electrical AC compressor, by which the renewable energy can be utilized to its full extent. Numerical Simulation is done and the Total Heat output, Temperature distribution along the bed, Pressure, charging time, discharging time, Mass flow rate are calculated. The storage system contains Erythritol as PCM in HDPE spherical capsule, having the storage capacity 345,121 KJ/hr (for the storage tank capacity) considering the latent heat and sensible heat of the Heat transfer fluid.
