Abstract: The present investigation deals with a transient parametric analysis of a solar residential heating system which comprises a corrugated absorber water heater and a water-to-air heat exchanger-cum-heat storage unit integrated to a residential building to be heated. The heat exchanger-cum-heat storage unit in the system is of the rock-bed type (used in the Thomason house in Washington DC, U.S.A. in 1959) in which a cylindrical water tank is surrounded by loads of rocks in an outer rectangular tank. A finite difference technique has been adopted to evaluate the performance for different parameters of the system. Although the system performance is dependent on other parameters also, the air flow rate was observed to influence the room air temperature most significantly. In addition, the mode of operation, i.e. whether the air flow is continuous or intermittent, influences the system performance greatly, higher and intermittent air flow rate resulting in a more stable and uniform temperature of the living space.
