Experimental investigation of efficiency of a novel conical solar collector
One of the methods to improvement of solar-to-thermal energy conversion is the design of geometry in solar collectors. In this paper, the new solar collector which is called solar conical collector has been designed and tested. The efficiency of solar conical collector was experimentally investigated by use of ASHRAE standard. Experiments were performed with water as a working fluid in the outdoor condition of Ahvaz city in the south of Iran. The results show that the average efficiency of a solar conical collector with 1m2 area of absorber plate and 0.6m diameter of cone is about 53% and it can be used as a useful new water heater.
