This work shows the construction of a mathematical relation between the discharge pressure and temperature in a centrifugal blower, with the objective to fit the molds refrigeration control in a glass container manufacture cell when the enviromental conditions presents variations, which modifies the quality of the final product. The used thermodynamic model allowed to identify a linear correlation between the two studied variables, as well as to numerically calculate the value of function’s parameters. The straight line of calibration (Tracking) was implemented in the manufacture cell, allowing a reliable control of the system of molds refrigeration with a small adjustment of the parameters.
