Análise do dimensionamento da carga térmica do bloco de salas de aula da Faculdade de Tecnologia na Universidade Federal do Amazonas

Abstract

With the development of the air conditioning device by Willis Carrier in 1902, known as air conditioning, various socioeconomic segments, such as industrial, commercial and even school sectors, applied air conditioning for the purpose of thermal control and comfort of the environment as needed. With the advancement of technology, several models and types of air conditioning were available in the market with different price ranges, which enabled the consumption of these products by a large part of society. The use of this equipment consumes a considerable amount of electrical energy for its operation, its popular use can generate a great impact on the electrical system in the country. In this context, in order to assess whether thermal comfort is met and its impact on electricity consumption, an analysis of the thermal load is carried out using the instructions provided by ABNT NBR 6401, 16401 and 16655-3 standards and scientific knowledge on thermodynamics for obtaining the results through explanatory research, observing the parameters of thermal comfort, such as: temperature, humidity, air movement, degree of purity, noise level and percentage of air renewal necessary for the classroom block Eng. Nelson Ribeiro Porto from the Faculty of Technology at the Federal University of Amazonas. After establishing the thermal comfort parameters, the necessary thermal load for the classroom block is calculated, and it is verified that the thermal comfort condition is not met because the air conditioning equipment has a lower capacity than the calculated thermal load. Thus, in the end, it is proposed to replace current conditioners with new air conditioning equipment that, in addition to meeting thermal comfort, can also reduce the cost of electrical consumption.
