DESIGN, DEVELOPMENT AND THERMAL PERFORMANCE EVALUATION OF A HORIZONTAL HEAT EXCHANGER UNIT FOR SK- 14 PARABOLIC SOLAR COOKER FOR OFF-PLACE COOKING

摘要

Different types of Solar Cookers developed for cooking are Box Type and Parabolic Solar Cooker (PSC). Parabolic Solar Cooker has a wide range of applications for making chapattis, baking of food material and for distillation due to its unique property of producing a practically higher temperature of nearly 250°C and it is inconvenience to the user due to its high amount of glare. The main objective of the present study is to use a Horizontal Heat Transfer Fluid (HTF) column as Heat Exchanger Unit and to evaluate the Thermal Performance of a Horizontal Cylindrical Heat Exchanger unit assisted PSC. Experiments were conducted for cooking of food on a normal day. Results show that Horizontal Cylindrical Heat Exchanger unit can be used for off-place cooking. Optimization of the system design parameters is under investigation.
