1 Periodic Analysis of Solarium-cum-Greenhouse

In this paper, an attempt has been made to evaluate the performance of solarium-cum-greenhouse by using the periodic analysis. Based on basic energy balance of each component of the solarium cum-greenhouse, a program in Matlab has been developed to evaluate room air, plant/isothermal mass temperature and thermal load levelling by matrix inversion. Temperatures at different layers of basement including air gap, phase change material (PCM) and soil have also been estimated. It is inferred that the temperature at bottom of PCM is highest due to minimum heat loss through the insulation. It is also observed that the best thermal load levelling is achieved for larger thickness of PCM
