Abstract: A cabinet for a vertical room air conditioning unit includes an upper section and a separate lower section having substantially similar cross-sectional dimensions to permit mating of adjacent ends when the upper section is stacked upon the lower section in a use position. Securing means, including tabs and screws hold the sections together in the use position, and the upper section acts as a plenum or air duct for the unit. For shipment or storage, the upper section telescopes down onto the lower section, and after having been rotated 90 degrees in the preferred embodiment, to form a compact space saving package.

Abstract: An ice cube making apparatus and method characterized by minimum excess meltage of the ice and minimum energy usage is disclosed. According to the apparatus a plurality of generally flat metalic tubes and interconnecting return bends form a serpentine evaporator path. A jacket member encloses the evaporator member to provide ice cube forming sites on both sides thereof. The jacket has internal passageways and external sites cooled by the evaporator member for forming ice cubes and includes a plurality of intersecting ridge portions whose inner surfaces form portions of the internal passageways and whose outer surfaces form the side walls for the sites for forming the ice cubes. The jacket may be made of flexible plastic material so that the filling of the jacket with water during a harvest mode causes flexing thereof to help to dislodge the ice cubes. Alternatively, the jacket is constructed of a pair of rigid plastic members which may be sandwiched together with the evaporator member inside.
