Abstract

PROBLEM TO BE SOLVED: To upgrade sealability of a connecting pie enclosed by a cutout circular form and a U-shaped cutout and to stabilize a pull-down time by constituting a pipe guiding apparatus having the U-shaped cutout of the same curvature as that of the circular form of a back surface heat insulation wall at a rear part of a controller. SOLUTION: The pipe guiding apparatus 24 having a U-shaped cutout 23 of a curvature of a circular form 14 is locked to a body cabinet by a fixing part. Thus, sealability of a lower half part of the form 14 becomes effective. Then, a side heat insulation wall 20 is inserted between a commodity containing warehouse and a controller, and before a back surface heat insulation wall 21 is inserted, sealing putty is coated in a gap between an upper half part of the foam 14 and the cutout 23 of the apparatus 24. Further, the wall 21 is inserted between the wall 20 and the cabinet. Thus, sealability between the upper half of the form 14 and a cutout 22 of the wall 21 becomes effective, and hence a pull-down time can be stabilized.
