Enhanced Solar Thermal Air Heater

S.K Deb , & B.C Sarma

The solar thermal concentrator made up of thin metallic reflector sheet is accountable for predominant convective heat loss through exposed surfaces & supporting structure. If the concentrator surface plate itself is used as a collector for harnessing absorbed heat by means of waste heat recovery, the same will give out an additional thermal output. Such a system used for air heating purposes was investigated in a bench model with it’s normal function of concentrated high temperature heat generation at it’s focal point where a thermal analysis and experimental results have been discussed.
