The author has presented results of calculating the efficiency of porous channels during the evaporation of a vapor– liquid Freon flow in the transition region of motion of the heat-transfer agent and with boundary conditions of the first kind. For the sake of comparison, use was made of a smooth-wall tube as the reference surface. As a result of the conducted investigations, it has been shown that with the Freon 12 heat-transfer agent, positive values of geometric and energy coefficients of efficiency can be obtained. The dependences of the efficiency coefficients on the basic operating-structural parameters of the model have been analyzed.
