Effects of the sizes and the arrangements of the insulated fabrics (shell plates, frames and beams) and the boundary conditions of the shipside fabrics, on the insulation performances of the insulated walls of refrigerated cargo hold have been investigated. The coefficient of the overall heat transmission, the inside temperature distribution, the isothermal line and the heat flow through the insulated wall, which are calculated by numerical procedures using the Finite Element Method, were adopted in order to evaluate the degree of the influence on the insulation performance. By performing the experiments with the refrigerated wall models, by the measurements of the insulation performances, with the practical refrigerated cargo holds, and by the simulation regarding the insulation performance, the effects of the variations in all the individual items given above as well as the hardwears such as lug pieces, steel pieces and fitting bolts were clarified quantitatively. In addition to these results, it was shown that the coefficient of the overall heat transmission of insulated wall with the complicated construction in the directions of three dimentions can be calculated numerically by applying the two dimensional FEM to the some divided cross sections of the wall.
