Análisis comparativo del comportamiento termodinámico de dos tipos de refrigerantes (R410A-32), para un sistema de refrigeración de leche con capacidad de 100 litros

Abstract

The present study is oriented towards the numerical analysis, simulation and comparison of the thermodynamic behavior of two refrigerants, R410A and R32, in the coil-type evaporator of a milk cooler with a capacity of 100 liters. The purpose is to make a comparison of all the phase change development of the mentioned refrigerants, through the results delivered by the simulation by means of CFD computational dynamics with the ANSYS software. To generate the thermodynamic cycle, a refrigeration system was designed in which real operating parameters were taken into account. For its interpretation, multiple simulations of the mentioned evaporator were carried out, whose dimensions were 4220 mm long and occupying a space of 422 x 246 mm. The results obtained were a better behavior in the phase change in heat absorption for the refrigerant R32 with a value of 10% above that of R410A in the tests carried out. As well as, the analysis showed that both refrigerants completely evaporate, this implies that the proposed fluids are suitable to work in a milk refrigeration system.
