Abstract: A refrigerating cabinet comprises a metallic external casing including a front wall, a rear wall, a left- and a right-hand sidewall, a top wall and a bottom wall with an opening formed in the front wall, an internal casing fitted into the external casing and having a plurality of walls which are disposed in opposing relationship with the individual walls of the external casing with suitable clearances therebetween, a pack of a heat insulating material filling the space created between the external and the internal casing, and a condenser tube for cooling down a refrigerant from a compressor before it is fed to pressure reduction means. The condenser tube extends from the compressor to the pressure reduction means by passing through the space between the external and the internal casing, and is disposed along the inside of selected corners each defined by adjoining two walls of the external casing.
