Coletor solar com tubo de vidro evacuado utilizando lâmpadas fluorescentes descartadas pela Universidade Estadual do Maranhão

Abstract

This paper proposes to build a prototype and verify its performance experimentally, to develop a model of solar collector with evacuated glass tubes, which were made from fluorescent lamps discarded by the university. It was not found in the Center of Technological Sciences of the State University of Maranhão - UEMA, which aims to simulate the operation of this type of collector and comparison of results with other existing collectors in the market, to determine the coefficient of heat exchange and the same performance . Being an inspiration for this paper, the search for economic and sustainable investments in the energy sector, and which refers us to the need for new sources of renewable energy, so the search for clean sources of energy. This has led to a growth in the construction of solar collectors. There are currently several types of solar collectors on the market. In Brazil, flat solar collectors are the most used. Due to their higher cost, evacuated tube collectors are rarely used. However, advanced technological studies promote the adequacy of its use making its acquisition economically more viable
