Performance Analysis of Flat Plate Solar Water Collector using Trapezoidal shape and Semicircular Tubes
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 8
Abstract
The flat plate collector forms the heart of any solar energy collection systems designed for operation in the low temperature range, from ambient to 60oc, or the medium temperature range, from ambient to 100oc. A well engineered flat plate collector delivers heat at a relatively low cost for a long duration. Generally flat plate collector consist of arrays of circular cross sectional tubes are bonded to the absorber plate to transfer of heat from absorber tube to working fluid. When using semi circular type tube blow to the absorber plate, the area of intimate contact is increases between fluid and absorber plate and also resistance due to adhesive is decreases. Also use of flat plate collector with trapezoidal shape with four sided mirror provision enhanced solar heat collection. The result shows that there is an improvement in the heat transfer rate. The heat transfer rate is increased by 45.79%. The maximum outlet temperature obtain was 56oc and maximum average absorber plate temperature obtain was 69.3oc with a 25kg/hr mass flow rate of water.
