Avaliação durante operação do sistema de aquecimento solar de água em habitações de interesse social

Abstract

Through the National Energy Plan 2030 and 2050, the National Plan on Climate Change with greenhouse gas reduction goals, and the increase of alternative energy generation andconservation sources and the creation of My House My Life Program to finance housing Of social interest that reaches a large mass of the population, Brazil wants to improve its energy matrix and implement sustainable development. With the mandatory use of solar water heating (SAS) from the new My Home My Life 2 Program (PMCMV 2) the goals of these strategic plans have the possibility of being followed and reached. However, the simple obligatoriness and installation of the system in states like Rio Grande do Sul with rigorous winter and many cloudy and rainy days may not be saving the energy expected. Social and educational conditions of the residents, lack of system maintenance, design error and installation, can be causes of possible non-economy. Therefore, this work seeks to carry out an evaluation during operation of the SAS installed in social housing in a city in the north of the state of Rio Grande do Sul. Through the verification of PMCMV 2 standards and specifications, pilot measurement in the favorable summer condition , Volume, water temperature, solar orientation) and clusters analysis in the population of the place, with quantification of generated economy one can understand that within the dwelling population of the place there are homogeneous groups, which differ in number of inhabitants, Age and income, but are characterized by low educational level and low income predominance, besides the lack of knowledge of the need of maintenance of the collectors. Thus, the non-saving of energy by some groupings and the great economy on the other hand, besides the two cases within the same group, show the influence of the profiles of the residents.
