Abstract

A compact integral solar water heater with an absorber plate area of approximately 1 m2 and a tank capacity of 75 1 was designed and constructed. The depth of the channel between the absorber plate and the insulated partition was varied from 5 mm to 15 mm and the performance of the heater at each channel depth was studied. At the same time, solar insolation was recorded using a solarimeter. Tests were also conducted under dynamic load conditions by drawing off 5 1 of hot water from the heater after every 2 hrs during day time. It was found that collector channel inlet and outlet temperatures, as well as the mean tank temperature increased in varying degrees with the increase in channel depth. The efficiency of the compact solar water heater also increased slightly with the increase in channel depth. Tests were also conducted with and without a baffle plate. The effect of the insulated baffle plate was to improve the performance of the heater. The performance of the integral solar water heater was generally found to be quite satisfactory with hot water in excess of 50°C available for most of the day and in the evenings.
