Abstract
Currently, the use of air conditioners has been increasingly frequent in Brazilian homes, due to the increase in purchasing power of some Brazilians in conjunction with extreme weather conditions even in colder regions. This amount reaches 20%, with the southern region responsible for 32% of energy consumption dedicated to air conditioning systems, due to the characteristic climate with cold summers and winters. This implies the search for air conditioners that maintain a more effective thermal sensation efficiency. Thermal comfort is essential for study environments, since students achieve better performance and use of concepts. This facilitates and motivates concentration, development of logical reasoning and development in teams, since they do not have to worry about the environmental conditions of learning. The correct sizing of air conditioners is essential to efficiently provide the ideal condition of comfort to the individual. In this sense, this work developed a study on thermal efficiency through calculations involving natural convection, considering ideal conditions of thermal comfort, offering better yields in the individual's activities. In this way, there was a concern regarding the comfort of the academic environment, where its dimensioning occurs in an ideal way when taking into account all the factors inherent in the design of the rooms. When we compare the method suggested by the authors in isolation from natural convection with the addition of the heat conduction method with the walls of the environment, there is a notable difference between the values of the thermal capacity necessary to maintain the conditions of comfort in the environment. As for the data from the necessary cooling capacity, to supply the heat loss from convection and heat conduction, it is concluded that the available equipment is sufficient to maintain the conditions of thermal comfort in the academic environment. In addition, it emphasizes the importance of a deep analysis of all the factors that influence the thermal efficiency when carrying out the dimensioning of air conditioning in the projects
