Projeto de um sistema de condicionamento de ar central para atender a um hotel – simulações realizadas no software Energyplus

Abstract

In the development of this work is present the project steps of an air conditioning system for a model hotel located in Brasilia. The methodology consists in determining the comfort conditions in which 80% or more of the occupants feel good to calculate the maximum thermal charge at the hottest time of year, to simulate the thermal charge through the EnergyPlus and contrast with the previously calculated. Then select equipment for a suitable indirect expansion system that meets the sensitive and latent heat demand. With the required leakage data for each equipment, design a closed loop piping for chilled water distribution and reuse, calculate a pressure drop in the pipeline due to the linear length and present items such as valves and piping outputs, and select the pump suitable for promoting water flow. The hotel thermal charge was approximately 32 TR and the difference between the calculated and simulated thermal charge in the EnergyPlus program is 2.2%, a value that did not influence the selection of equipment. After the equipment selection, the estimated cost for the installation of the air conditioning system was R $ 163,810.00.
