This work presents a study on the calculation of transmittance in an Air Handling Unit (AHU) through three methods: theoretical estimation, experimental approach and numerical simulations. First, estimation based simplified models heat mass transfer AHU was employed. In addition, tests were carried out real under controlled conditions, obtaining temperature measurements inside outside unit. These data used to calculate using predefined formulas. Finally, simulations performed specific sections global model, with without radiation considering its influence. The provided detailed results flow behaviour distribution. obtained compared analysed assess accuracy applicability methods. research contributes knowledge understanding AHUs, providing valuable information for design optimisation Heating, Ventilation, Conditioning (HVAC) systems.
