Abstract: A mechanism to control the temperature in the freezer and fresh food compartments of a side-by-side refrigerator includes an elongated support plate mounted in the upper portion of the fresh food compartment. A fresh food thermostat is mounted under the plate adjacent to the mullion separating the compartments and its control shaft is aligned with an opening in the plate. A pinion gear is connected to the shaft and is positioned above the plate. A freezer thermostat is mounted under the plate at a position more remote from the mullion and its control shaft is aligned with an opening in the plate. A pinion gear is connected to the control shaft and is positioned above the plate. A fresh food rack gear is slidingly mounted on the plate remote from the mullion and includes an elongated arm with teeth that engage the fresh food pinion gear. A freezer rack gear is slidingly mounted on the plate close to the mullion and includes an elongated arm with teeth that engage the teeth on the freezer pinion gear.

Abstract: A side by side refrigerator has a vertical evaporator formed from an elongated tube wrapped with a ribbon of material having spine fins extending substantially perpendicular from the elongated tube. The elongated tube has elongated straight runs joined by return bent ends to define a vertically extending evaporator having a generally oval spiral or configuration. In one embodiment, the elongated straight runs are spaced from each other throughout the vertical length of the evaporator to provide a space of constant area for air flow.

Abstract: A spine fin refrigerator evaporator is formed of lower and upper sections of elongated straight runs, which have fins thereon and have their ends connected to each other by return bent ends. The lower section is formed with two rows of the elongated straight runs in an A shape to provide a passage therebetween through which air initially flows through the evaporator so that frost can be gathered without blocking air flow therethrough. The upper section has three rows of the elongated straight runs with the fins of adjacent rows overlapping each other to provide an efficient heat transfer from the refrigerant in the elongated straight runs to the air whereby the lower and upper sections combine to provide a practical and efficient evaporator. If desired, the upper and lower sections can be vertically spaced from each other to have a defrost heater disposed therebetween.

Abstract: A pair of packing supports prevents movement during shipment of two shelves, which are slidably supported on vertically spaced shelf supports integral with inner side liners of a refrigerator cabinet. Each packing support, which is formed of corrugated cardboard, for example, has a shelf support portion wedged between two shelf supports on one of the inner side liners to prevent vertical and fore and aft motion of the packing support. Each packing support has a shelf retaining portion formed integral with the shelf support portion and bent at approximately 180.degree. thereto. The shelf retaining portion receives one end of each of the shelves whereby it is compressed so that there is no motion of the packing supports towards each other.

Abstract: A household refrigerator shelf assembly comprising a removable rigid unitary frame having two spaced apart shelf brackets, a front horizontal support member and a rear horizontal support member, both being rigidly attached to and spanning the distance between the brackets. The rear horizontal support member as viewed in lateral cross-section has a vertical wall at the top and a depending rearwardly directed horizontal flange terminating in a downwardly directed terminal end portion spaced rearwardly from the vertical wall, the bottom of the vertical wall having a forwardly directed horizontal flange with a downwardly directed rib. There is a reflector member attached to the rear horizontal support member and spanning the distance between the brackets. The reflector member as viewed in lateral cross-section has an upper vertical portion with a right angle bend at the bottom and a bottom portion.

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 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.

Abstract: The present invention relates to a heat pump that utilizes unidirection refrigerant flow wherein the condenser and evaporator retain their functions, but the air directed across them is redirected for different operations. While the heat pump is operating in the cooling mode, outdoor air is passed in heat exchange relationship with the condenser for liquefying the refrigerant and outside again; and indoor air is passed in heat exchange relationship with the evaporator for cooling the air circulated again. Conversely, in the heating mode, outdoor air passed in heat exchange relationship with the evaporator for vaporizing the refrigerant, then outside again; and indoor air is passed in heat exchange relationship with the condenser for heating the air and circulated again.

Abstract: The present invention relates to a heat pump that utilizes unidirection refrigerant flow wherein the condenser and evaporator retain their functions, but the air directed across them is redirected for different operations. While the heat pump is operating in the cooling mode, air dampers are positioned so that outdoor air is passed in heat exchange relationship with the condenser for liquefying the refrigerant and outside again; and indoor air is passed in heat exchange relationship with the evaporator for cooling the air circulated again. Conversely, in the heating mode, the air dampers are positioned so that outdoor air passed in heat exchange relationship with the evaporator for vaporizing the refrigerant, then outside again; and indoor air is passed in heat exchange relationship with the condenser for heating the air and circulated again.

Abstract: The present invention provides an air conditioning system for use in a mobile home. The system includes securing a mounting means to the support structure of the mobile home and an air conditioning unit that is adapted to be removably secured to the mounting means. When installed on the mounting means, the air conditioning unit is aligned to deliver conditioned air into the interior of the mobile home through its built-in air distribution system.
