According to the present invention, an air directing housing is provided for an air conditioning unit of the type having a basepan which supports indoor and outdoor sections. The basepan includes a vertical wall extending upwardly for a part of the height of the unit to define a lower portion of a partition which separates the unit into the indoor and outdoor sections. The indoor section includes an evaporator disposed in the basepan generally forwardly of the partition. A centrifugal fan is mounted between the evaporator coil and the vertical wall for rotation about an axis extending from front to back of the air conditioning unit. The fan is a centrifugal flow fan which has a circular inlet at the front thereof. The air directing housing is adapted to be mounted in the basepan rearwardly of the evaporator coil and surrounding the fan. The housing includes a lower section having a front wall which has a circular opening formed therein which is substantially coextensive with the circular inlet of the fan. The lower section also includes an interior scroll section for receiving the fan, and an open back. The air directing housing further includes an upper section defining an enclosed top structure for cooperation with the upper discharge structure of the lower section to define the air discharge opening of the air conditioner. The upper section further includes a rear wall having a lower edge adapted to engage the vertically extending wall of the basepan to define the upper portion of the partition. As a result, when the lower and upper air directing housing sections are installed in the housing, they cooperate with one another, the basepan, and the vertically extending wall to define the fan housing, the air intake and air discharge of the air conditioner.
An air conditioning unit having an indoor section and an outdoor section separated by dividing wall. The outdoor heat exchanger and fan are enclosed within a housing that is split into a stationary lower wall section and a removable upper wall section which, when removed, provides ready access to the outdoor heat exchanger. A hole is placed in the bottom of the lower wall section in front of the fan so that condensate can be drawn into the unit by the fan and distributed over the heat exchanger surfaces. Vanes are placed on the inside wall of the housing to enhance the distribution of the condensate.
A room air conditioner is provided having an evaporator coil located in a front part of the room air conditioner, a condenser coil located in a back part of the room air conditioner, and a wall separating the front part from the back part. The wall prevents a free flow of air between the front part and the back part. A portion of the wall, extending less than a full width of the air conditioner, is formed of metal. An air moving device positioned in the front part creates an air stream flowing through the evaporator coil and out through an air outlet in a front grill of the air conditioner. An air housing surrounds at least a portion of the air moving device and forms an air flow path in the air conditioner, the air housing forming at least a part of the wall. The metal portion of the wall is mounted to the room air conditioner independently of the air housing.
