Abstract
Abstract For air conditioning recreational vehicles and other interior spaces beneath whose floors there is open air space, a unitary, through-floor air conditioner is provided. Adjustable vertically, only its upper evaporator compartment need be within the room space; hence removable furniture may be positioned above it. For servicing, the blowers and their motor, with intermediate divider walls, lift out vertically as a unitized assembly. Removal of this assembly provides access for servicing the other components.
