Análisis numérico y comparación del comportamiento termodinámico de los refrigerantes R410A, R407C y R32 dentro de un condensador helicoidal, utilizado para la calefacción de un galpón de pollos de engorde

Abstract

This study consists in the analytical design of a heat pump through an analysis of the compression and condensation process that occurs in it and the possession the selected fluids. To analyze the aforementioned pump, the research proposes the use of various refrigerant fluids which are, the R410A, R407C and R32 to perform out a comparison to select the most suitable refrigerant for the application determined in this project which is, the generation of heating for a poultry housing with the purpose is to perfect the breeding development poultry for fattening and reducing energy consumption through a system that has a lower environmental impact than that produced by heating systems with LPG currently used. To understand and interpret the thermodynamic cycle that occurs in the heat pump, multiple CFD simulations of the critical element of study of the system were carried out, which is a helical condenser of the following dimensions: 95.3mm wide, 16.7mm between each step, external diameter of the tube of 9.5mm and internal diameter of 8.2mm. The results were tabulated from the simulations of the condenser using each of the refrigerants mentioned above and showed that under certain boundary conditions specified in the development of the study, all fluids condense completely in the critical element of analysis and that the refrigerants R407C and R410A show temperatures similar to the ideal temperature needed in a poultry house during the first week of the rearing of poultry.
