Produção de um programa computacional prático para auxiliar cálculos envolvendo o projeto de redes de condicionamento de ar

Abstract

The need of air conditioning for environments is an increasingly need present in society, either for human comfort or process control. Many air-conditioning systems use ductwork to conduct the air to environment and to return it to air conditioners. Thus, the importance in the design of pipeline network is directly related to the results of air conditioning in the environments, control of temperature, pressure, humidity, speed and degree of air purity. In addition, the project of a pipeline network influences the cost of an air conditioning system. The network design calculations involving pipelines are sometimes cumbersome and, in some cases, dependent on abacus, which makes it susceptible to significant errors in the project. In this study we aimed to develop a computer program, using spreadsheets to assist in the calculations involving pipeline network project. Calculations have been shown for a manually study case with use of abacus and calculations using spreadsheets developed. The results showed significant differences for calculations of pressure loss. Also, besides being more accurate, calculations using the program optimize the process of designing a pipeline network.
