OSTI ID:5112361
This patent describes a package terminal air conditioning unit that is formed of an interior unit disposed within a building, a separate exterior unit disposed outside the building, and connecting duct means connecting the interior unit to the exterior unit, in which the interior unit comprises a cabinet, an indoor heat exchanger coil, and a cylindrical fan which includes a cylindrical fan rotor, means mounting the rotor in the cabinet, and a volute shaped member. The exterior unit comprises an outside heat exchanger coil and an outside cabinet separated from the indoor cabinet and housing the outdoor heat exchanger; and the connecting duct means comprises a pair of refrigerant lines passing between the two cabinets for connecting the two heat exchanger coils, a compressor, and an expansion valve to complete an air conditioning circuit. The improvement comprises the compressor contained in the indoor cabinet of the interior unit so that the exterior unit is kept as small and light as possible, and has a relatively small power requirement as compared with the interior unit. The indoor cabinet is molded of a synthetic resin and is formed of a base section, a back section, and a removable front cover section that interlock to form an equipment compartment that houses the compressor and an adjacent air duct that connects an inlet vent and an outlet vent with the indoor heat exchanger coil situated therebetween; both of which compartments are opened by removal of only the front cover section.
