Heat conversion design using peltier thermoelectrics with greenhouse effect heating system and mobile nitrogen cooler following the sun position

Abstract

A solar thermal-to-electricity conversion system that optimizes the temperature difference between hot and cold sources has been designed using Peltier thermoelectric. The system consists of three main components, namely the heating system, cooler, and drive to position the prototype following the direction of motion of the sun. With a greenhouse effect concept, the heating system at the top keeps the temperature in the acrylic room warm. The hot side of the Peltier is placed with an aluminum plate and andesite stone as heat conductors and storage. The cooling system uses a metal-wrapped fluid as a source of cold temperature equipped with temperature-reducing aluminum foil and nitrogen gas to keep the fluid at a low temperature. Finally, the drive system uses a hydraulic to move the design module following the direction of motion of the sun, whose light will be focused by a convex lens to concentrate. The Peltier is assembled in series and step-up to increase the output voltage to produce maximum results. This prototype design can hopefully contribute to the development of renewable energy.
