Determinação do consumo de energia elétrica para os sistemas de ar-condicionado – um estudo de caso

Abstract

The survey of the thermal load of refrigerated environments allows us to determine in a safe and concrete way the amount of thermal load required for the studied environment, also the conditioned air systems’ electric energy consumption of. Any educational institution should maintain its students in a comfortable environment to achieve a better educational performance. The objective of this work is to present a case study at the Federal Institute of Education, Science and Technology of Para - Campus Parauapebas, determining the electric power consumption of the classrooms’ air conditioning at this institute. Initially, a flow chart was proposed to study activities to be carried out in order to guarantee this reach. At first, it was necessary to catalog the values for the currents and voltages for each of the air conditioning units in the classrooms of the institution under study, thus, one can identify the average monthly consumption for each appliance. With this information, it is possible to demonstrate the monetary expenditure of the energy consumption. Then it is possible to estimate of the financial economy after the survey of the total consumption of the electric energy. It should be pointed out that this cataloging was carried out in more intense seasonal periods and in certain months to complete the information for the values to be obtained (voltage and current). In order to carry out the project, we have used important sources of exploratory research, aiming to expand the study of the case. The results showed a voltage variation around 209 to 214 Volts (V) and a current of 11 to 14 Amperes (A) for power devices of 18,000 BTU from that point, it is tried to establish efficient methods to reverse the economic picture of the institution through analyzes and perspectives carried out according to the data collected.
