Abstract
Front of a need for residential comfort with regard to heating water, whether for bathing, washing clothes or cutlery, and observing that many existing commercial heaters have a high cost of implementation or maintenance, this work brings the proposal to study of a low-cost water heating unit using solar radiation in order to achieve a better quality of life for people with lower purchasing power. This does not prevent its use by others people who believe in conscious energy consumption in order to better preserve the non-renewable energy sources currently used in most water heating systems. According to the Brazilian Atlas of Solar Energy (2017), the annual average of irradiation in Brazil is around 4750 Wh/m²∙day, with the highest numbers recorded in the Northeast and Midwest regions, where a experimental studies of a solar collector and a parabolic solar concentrator will be done in order to make a thermal and economic comparison of each one, thus having an analysis of the possibilities of implementation in communities that choose to have the comfort of heated water without the use of electricity. The comparison is given through temperature analysis through thermal sensors coupled in different parts of the systems, which are checked throughout the day, both devices being tested together under the same conditions. Solar water heating systems are a good alternative for domestic use, aiming to reduce energy consumption because it is sustainable, since this system uses renewable energy from solar radiation.
