Estudo de viabilidade técnica e econômica sobre o aquecimento de água por sistema de coletores a vácuo: um estudo de caso em um hotel

Abstract

Solar thermal energy is a source of great potential for heating water, especially for sanitary purposes, given the high levels of solar irradiation in Brazil, specifically in the northeastern region of the country. Replacing the electric shower - a villain in terms of electricity consumption - with a solar heating system (SAS) generates benefits for the entire community, including electricity utilities, consumers, and the environment. This study aims to assess the technical feasibility of implementing a Solar Heating System (SAS) using vacuum collectors to meet the demand of a hotel with limited floor space located in Lauro de Freitas, Bahia. However, despite the benefits and great potential for using the technology in Brazil, its penetration is still very modest compared to countries with lower solar incidence or even the south and southeast regions of the country.
