Pacotes computacionais para sistemas de condicionamento de ar

Abstract

In air conditioning and ventilation systems, you can not always install the equipment in the air conditioned environment and there are several factors contributing for this restriction, as: the required air flow, the acceptable noise level, the environment aesthetics, the desired air range, among others. For such cases, systems that use one or more pipeline extension sets in order to get the desired air conditioning state to a room are adopted, thereby allowing the engineer to meet the project’a demands. For such cases, systems that air is drawn into the room conditioned by one or more extensions of pipelines are adopted, thereby allowing you to meet the demands of each project. This thesis aims at developing a reliable tool to scale extension tubes for air conditioning systems in general. Microsoft Excel will be used as a resource to develop a program which will be calculated in the various pressure losses that occur in a system and these are benchmarks for other calculations that will result in the specification of the geometry and dimensions of pipes and other components. The calculations will be developed based on the theory of fluid mechanics and in this work are also presented solutions in technical books and catalogs from manufacturers such as abacus, selection curves for fans and Brazilian technical standards.
