Performance Evaluation of Dual Purposes Solar Heating System Using Heat Pipe Evacuated Tube Solar Collector

The aim of this work is to develop dual purposes solar heating system using a heat pipe evacuated tube collector. transfer fluid between the thermal loads and collector loop was oil. study provided two loads; water baking/cooking that had experimentally investigated under various weather conditions. experimental pilot unit installed in Solar Energy Department, National Research Centre, Giza, Egypt. Several test runs were performed measure all assigned parameters affect performance. designed provide hot oil surrounding inner vessel baker with temperature up 250o C while raw food can be baked/cooked outlet energy used for via an immersed coil storage tank; then relatively cooled returned circulating pump. tested positively contributed baking cooking providing as well. It considered environmentally friendly significantly enhance sustainable communities. capable produce 85 oC average about 60 during day which suitable residential industrial process well auxiliary electric source case urban areas renewable like biogas or hydrogen fuels rural isolated areas.
