THERMAL EVALUATION OF SOLARIUM-CUM-PASSIVE SOLAR HOUSE

The thermal analysis of a solarium-cum-passive solar house, based on energy balances of its different components, has been presented. The effects of link walls, viz. air collector, water wall and transwall, and isothermal mass have been incorporated in the analysis in addition to system as well as climatical parameters. Analytical expressions for room temperatures of the solarium and living space have been derived. Numerical calculations have been carried out for a typical day of Srinagar to evaluate the thermal performance of the systems, along with optimization of the solarium for best thermal load levelling for the living room. Some of the results are as follows: (i) the transwall, as a link wall, gives better results and (ii) the solarium room temperature is higher during the day and becomes lower during the night in comparison with the living room temperature.
