The author and other investigators have reported experimental results that coefficients of mass transfer under frosting conditions decreased as the wall temperature decreased. On the other hand, in the previous paper,the theoretical analysis of heat and mass transfer under frosting conditions has been made with satisfaction of a thermodynamic equilibrium between temperature and concentration of water vapor in humid air. In this paper,the experimental results of Nusselt number Nu and Sherwood number Sh are compared with the analytical ones,and Sh/Nu is discussed and analyzed in consideration of phase change process of water vapor in humid air.
