SINOPSIS

The effect of certain independent variables on the specific cooling power, the cooling power density, and on the coefficient of performance (COP) of a chemisorption refrigerator was determined. The independent variables were the length and thickness of the sorbent bed, the heat transfer fluid flow, the fins thickness and pitch, the type of the sorbent, the cycle time, and the thermal contact resistance. The study was conducted with the aid of simulation of a two-dimensional heat transfer mathematical model. The simulation conditions were chosen according to fractional factorial and central composite designs. The type of sorbent was the most important variable to increase the cooling power and the COP. When the analysis was done with account only for the consolidated type of sorbent, the length of the sorbent bed and the use of fins were not critical to the refrigerator performance. Moreover, the cooling power was negatively affected by the increase in the bed thickness and cycle time, whereas the COP was positively affected by the increase of these variables. Such a result indicates that it is not possible to reach a maximum cooling power and a maximum COP through the manipulation of the bed thickness and cycle time. However, by using the central composite design and contour plots, it was possible to determine the values of these independent variables in which both the cooling power and the COP had the same relative increment above their minimum value in a specified range of cycle time and bed thicknesses.
