Desenvolvimento de um calorímetro psicrométrico para fins didáticos para ensaios de condicionador de ar tipo janela

Abstract

Psychrometric calorimeters are devices designed to measure the cooling capacity of air conditioners through the measurements of dry bulb temperature and wet bulb temperature at the inlet and outlet of the evaporator. The present study aims to design a low cost psychrometric calorimeter, meeting the associated standards and norms, to analyze the cooling capacity of a window type air conditioner with a rated cooling capacity of 7500 BTU / h (2.2 kW). The methodology used to make the appliance is shown in a sequence where the materials and items used are defined, the assembly and construction proposal and the design. Following the construction of the apparatus, two tests are performed to determine the cooling capacity of the machine at different ambient temperatures, one of which was carried out at 26 ° C ambient temperature and the other at 29 ° C. Lastly, preliminary results of the cooling capacity of each test are displayed, where for test 1 it was 2.31 kW and for test 2 it was 2.5 kW.
