Análise e dimensionamento de termoacumuladores para o grupo consumidor A4, tendo como exemplo de aplicação a Universidade Tecnológica Federal do Paraná campus Medianeira

Abstract

This study focuses on the sizing of thermal accumulators for the Federal Technological University of Paraná, Medianeira campus. The dimensioning is designed for a cooling system with an emphasis on cold water. The central issue is how the implementation of thermal energy storage systems can improve energy efficiency in a specific consumer group. The justification lies in the growing demand for electricity, the pursuit of sustainable solutions, and the ability of thermal accumulators to enhance energy efficiency, reduce peak tariffs, and complement renewable energy sources. The objective of the study is to analyze and size thermal accumulators for the A4 tariff group (university). Specific objectives include selecting the most efficient thermal accumulator, strategies to optimize electricity consumption, and financial forecasting. The theoretical framework discusses energy efficiency and the use of thermal accumulators in various sectors. Studies and applications of thermal accumulators in commercial buildings, industries, and HVAC systems are highlighted. Thermal accumulators are simple devices that heat or cool water and maintain it at a predefined temperature. The tariff structure includes the green tariff, with hourly variations in energy prices. The object of study is UTFPR-MD. The method involved economic analysis and sizing of the thermal storage system, with a focus on energy savings during peak and off-peak hours. Material resources used include Microsoft Excel software for sizing thermal storage systems and financial calculations.
