Parametric studies of a noval solar water heater
Extensive theoretical and experimental studies on a noval solar water heater which was developed earlier by Garg in India, are carried out. In this water heater, the absorber plate performs the dual function of absorbing the solar energy and storing the heated water. In the theoretical study, energy balance equations are written on each node of the collector, considering their capacity effect, conduction loss effect and various other heat loss effects respectively. Resulting set of equations are converted in the finite difference form and then solved by digital computer. Solar radiation and ambient temperature are represented by Fourier series in theoretical analysis. Its night cooling drawback is somehow checked by covering the collector system by insulation cover during night time and also by using a insulating baffle plate inside the tank adjacent to the absorber plate. It is observed that by using the insulation, the collector performance can be improved significantly. By introducing a baffle plate the performance of the heater is improved during the day as well as night time.
