Abstract

Abstract A packaged terminal air-conditioner comprises a housing which includes a cabinet, a bottom plate and front cover attached to the front of the cabinet being mounted through a house wall and the like. On the front side of the bottom plate, there is provided a fan casing unit having a partition which divides an inside of the housing into indoor and outdoor sections. A propeller fan and an outdoor heat exchanger are arranged in the outdoor section, while in the indoor section, a cross-flow fan is mounted in the front vicinity of the partition of the fan casing unit and extending in parallel with the surface of the partition and an indoor heat exchanger is arranged in front of the fan casing unit. The partition serves both an air guide portion for guiding an indoor air heat-exchanged to the cross-flow fan and a scrolling portion of the cross-flow fan for producing an air stream. In assembling, the cross-flow fan is mounted on the supporting portion of the fan casing unit, then the indoor-heat exchanger is mounted on the fan casing unit, the fan casing unit is placed on the bottom plate on which the outdoor heat exchanger and the propeller fan are mounted in advance, thereafter the bottom plate is inserted into the cabinet and the front cover is attached to the cabinet.
