Abstract: A refrigerator freezer compartment has an evaporator forward of its rear wall for maintaining the freezer compartment at the desired temperature with a cover forward of the evaporator to define the rear of the freezer compartment within which food may be stored. A side ladder is attached to each side wall of the freezer compartment. A horizontal bar extends between the bottoms of the two side ladders to which it is attached and is secured to the bottom of a center ladder. The upper end of the center ladder may be supported within a nipple supported by the top wall of the freezer compartment or secured to a horizontal bar extending between the tops of the two side ladders and secured thereto. Each of the side ladders and the center ladder has a column of rectangular shaped slots to receive portions of an adjustable shelf so that one shelf may be mounted between one of the side ladders and the center ladder and another shelf may be mounted between the other side ladder and the center ladder.

Abstract: In a self-contained air conditioner unit of the reversible refrigeration type having cooling and heating cycles, a no-drain heat pump is provided wherein in the heating cycle, water collected on the outdoor heat exchanger operating as the system evaporator is transferred to the indoor section. The condensate is directed into the indoor air flow where it is atomized and directed through the relatively warm indoor heat exchanger operating as a condenser to humidify the air. Control means are provided which produces a signal in the event the condensate when present is not being transferred to the indoor section during the heating cycle.

Abstract: In a self-contained air conditioner unit of the reversible refrigeration system type having cooling and heating cycles, a no-drain heat pump is provided wherein in the heating cycle, water collected on the outdoor heat exchanger operating as the system evaporator is transferred by a condensate disposal system to the indoor section. The condensate is atomized and directed into the indoor air flow and against the relatively warm indoor heat exchanger operating as the condenser to humidify the air. Control means are provided that prevent the condensate disposal system from directing condensate into the indoor air flow during the cooling cycle.
