RESUMO
The present work describes the experimental analysis of flow of refrigerant R404a through short tube orifices, for different diameters and operating conditions. An experimental apparatus was constructed to provide the desired operating conditions. The experimental data covers upstream pressures from 210 psig to 240 psig, downstream pressures from 104 psig to 185 psig and inlet subcooling from 1,30 o C to 18,02 o C. A literature review revealed, at the time of publication, the absence of works on the flow of R404a through short tube orifices. A correlation of the experimental data, to be used in future simulations of short tube orifices, is presented. The results constitute an original contribution to the study of flow of R404a through short tube orifices.
