Estudo de caso de um plano de eficiência energética no sistema de refrigeração de um shopping center em Fortaleza

Abstract

The study presented in this work of conclusion's course is an analysis of the energy efficiency of an air conditioning system in a mall at Fortaleza - CE. The air conditioning at the facility is one of the responsible for the high consumption of electric energy, which generates a high cost for the company that manages the mall, since electricity is the second largest cost of any company. The operation of the mall has been proposing actions and techniques for the efficient management of the use of energy resources, especially the reduction of energy consumption. For this, routines of good practices of energy use and of analysis of indicators were created with the main goal of monitoring the consumption of electric energy by the use of new technologies and procedures. The consumption of chillers between the years 2016 and 2018 was specifically compared between July 2016 and June 2017 with July 2017 to June 2018. The results obtained were satisfactory given the presented energy cost matrices during this period. Thus, by comparing consumption, it was verified that, with the implementation of economic actions, there was a 12,8% reduction in CAG's energy consumption, which indicates an average saving of 32 thousand reais/year.
