EXPERIMENTAL INVESTIGATION OF PARABOLIC TROUGH COLLECTOR SOLAR AIR HEATER

The sun which is source of all energy the solar energy which is available from sun can be used for many application water hearing, drying and power generation like Solar air heaters are the systems those collects solar energy and transfers the heat to passing air, which is either stored or used for space heating. Solar collector plays a vital and important role in solar air heater. Experimental investigation of parabolic trough collector with different material aims to compare two types of solar air heater (1200×500×120) mm in which both arrangement having straight tubes 1.2 m length with parabolic trough collector and thermal performance will be carried out to compare which arrangement is more efficient. The absorber plate of stainless steel sheet with 2 mm thickness and attached with solar air heater and study the thermal performance of such air heater using K type thermocouple.
