Previous issue date: 2016-07-29 / Foi estudado um sistema solar de aquecimento de ?gua para banho composto por um coletor solar com tubos absorvedores de PVC e reservat?rio t?rmico fabricado a partir de um tambor de polietileno de 200 litros. Os tubos absorvedores foram unidos por conex?es em T e joelhos de PVC, e a configura??o da grade absorvedora formada foi em s?rie/paralelo, para proporcionar uma maior capacidade de aquecimento, aumentando-se a temperatura da ?gua circulante. O reservat?rio t?rmico constitu?do do tambor de polietileno foi revestido por chapas de a?o galvanizado e entre as duas superf?cies foram aplicadas espuma de poliuretano, um material de excelente capacidade de isolamento t?rmico. O sistema de aquecimento proposto tinha como principais caracter?sticas o baixo custo e simples processos de fabrica??o e montagem. Ser?o apresentados os processos de fabrica??o e montagem do coletor e do reservat?rio t?rmico alternativo, e resultados de testes que demonstrar?o a viabilidade do sistema de aquecimento proposto para promover o aquecimento de ?gua para banho para uma fam?lia de quatro pessoas. Demonstrou-se que o coletor solar proposto teve capacidade de promover o aquecimento da massa de ?gua do RTA a uma temperatura m?dia de 50?C, em um ?nico dia de aquecimento, temperatura muito acima da temperatura ideal de banho e que o sistema de aquecimento tinha autonomia de quatro banhos para um ?nico dia de teste. A perda t?rmica do coletor solar estudado esteve muito acima da relativa aos coletores solares convencionais de mercado, mas n?o inviabilizou a utiliza??o do coletor solar proposto para utiliza??es residenciais. O coletor solar de grade mista apresentou custo de fabrica??o correspondente a 50% do relativo a um coletor solar convencional de mercado e o reservat?rio t?rmico alternativo apresentou perda t?rmica compar?vel ? de reservat?rios convencionais de mercado, com custo de fabrica??o 70% menor. / Solar water heating is one of the main applications of this energy source, because it has already proved that the use of solar heaters can bring significant cost savings to the energy matrix by use of electric showers, large consumers of energy. Within that context was studied a solar water heating system for bath, consisting of a solar collector with pipes and PVC thermal reservoir absorbers made from a polyethylene drum 200 liters. Absorbing tubes were joined by T-connections and knees of PVC, and setting the grid formed absorber was in series/parallel, to provide greater heating capacity, increasing the temperature of the circulating water. The thermal reservoir composed of polyethylene drum was coated on galvanized steel sheets and between the two surfaces have been applied polyurethane foam, a material of excellent thermal resistance. The proposed heating system had as main features the low cost and simple processes of manufacture and Assembly. Will be presented the processes of manufacture and Assembly of the collector and the heat reservoir, and results of tests that will demonstrate the feasibility of the proposed heating system to promote the heating of water for a shower for a family of four. It was demonstrated that the proposed solar collector had ability to promote pasta water heating thermal tank alternate an average temperature of 50? C, in a single day, well higher than the bathroom, between 36-38? C, and the heating system had autonomy of four baths for a single day of testing. The solar collector heat loss studied was very above on the conventional market solar collectors, but not impeded the use of solar collector proposed for residential uses. The solar heating system alternative studied had cost corresponding to 40% of the conventional market, its economic viability.
