A REVIEW PAPER ONPERFORMANCE ENHANCEMENT OF COCENTRIC PHOTOVOLTAIC THERMAL RECEIVER SYSTEMS BY USING EFFECTIVE COOLING METHODS

MECHANICAL

In the current investigation, a novel geothermal based cooling innovation is produced for the cooling of PV and CPV framework, which are named as earth water heat exchanger (EWHE) and earth air heat exchanger (EAHE). For the advancement of such innovation, the reenactments were done in TRNSYS by coupling EWHE with unglazed PV boards. The reproduction results demonstrated that the presentation of the coupled (unglazed PV/T+ EWHE) framework scarcely relies upon the EWHE pipe material and line width. Accordingly, rather than utilizing costly electrifies iron (GI) and steel pipes, less expensive line material could be utilized with more modest measurements, similar to 12 mm, to accomplish ideal execution. Further recreation considers were done on coated PV/T frameworks with EWHE cooling by creating one dimensional numerical model utilizing MATLAB vR12a. The scientific models were created for two kinds of coated PV/T frameworks for example cylinder and-sheet and wide water channel. To approve these two models with the mimicked one. It was seen that, with the utilization of EWHE cooling, the electrical effectiveness of cylinder and-sheet PV/T framework is expanded by 1.5% when contrasted with without cooling.
