Resumen

This document compares the best alternatives regarding two working fluids and three operating conditions for a helical baffle in a shell and tube heat exchanger. It begins by investigating issues related to the study problem, validated by scientific documents, the most relevant properties of the working fluids and the material used (INOX 304) for the study are presented. The deductive analytical method used with the characteristics obtained shows how the heat transfer area increases as the angle of the baffle increases, the boundary conditions of the water are also detailed as: 10 ℃ at the entrance with a velocity of 0.8 m/s at a pressure of 25 psi evaluated in the Ansys Fluent software, determining that the best option for residential water heating is the use of refrigerant R744 with a 25° inclination for the helical baffle. The results show that under these parameters a better heat transfer is obtained reaching a temperature of 31.5 ℃.
