PURPOSE: To prevent a rate of utilization of volume within a loading box from being reduced even if an evaporator is arranged within the loading box by a method wherein the evaporator for a freezing facility is installed at a recess formed at a thermal insulating layer part of a wall surface and an outer surface of the evaporator is arranged at a position where it is not projected out of a substantial same plane as that of the wall surface. CONSTITUTION: A ceiling 8 has a structure in which a thermal insulating layer 12 made of a synthetic resin foam material is arranged inside a thin metallic plate 11 provided with a corrugation at a longitudinal direction of a loading box 4 as required and either the synthetic resin or wood 13 is arranged in tension inside the thermal insulation layer. A front end of the ceiling 8 is provided with a recess 14 formed with the thermal insulation layer 12 being formed thin. An evaporator 15 formed thin is fixed in the recess 14. The evaporator 15 has a thin-type blower driven by a thin flat plate-type electrical motor and a gasifying part for the refrigerant is also formed into a thin shape. Accordingly, a lower surface of the evaporator 15 becomes approximately the same flat surface as the inner surface of the ceiling 8 and then a sufficient thermal insulating operation can be assured. |
