Abstract

Air-conditioning apparatus particularly adapted for small cars of the Volkswagen type and comprising an encased condenser and evaporator forming a reversible heat exchange unit of the heat pump type which may be conveniently stowed in the space behind the rear seat and which directs heated or cooled air forwardly along the interior roofline, then reversely through the passenger space. The limited space beneath the dashboard, therefore, is unencumbered by the evaporator and control units as heretofore and air circulation is improved, while installation is facilitated.

Claims

1. The combination with a vehicle having a rear engine compartment, a passenger compartment, a dividing wall structure therebetween including a floor portion defining open space there beneath, a transverse seat spaced forwardly from said wall structure, and a utility compartment between said wall structure and said seat, of a compact air-conditioning unit resting on said floor portion including segregated condenser and evaporator devices and an expansion valve, piping connecting said devices and said valve, and blower means for drawing air from the lower portion of said passenger compartment across said evaporator device and forcing said air into the upper portion of said passenger compartment, there being first and second openings in said wall structure adjacent and communicating with said condenser and spaced apart longitudinally of the vehicle, and air deflector means projecting downwardly and forwardly from the rear edge of said first opening into said open space, said second opening communicating with said open space rearwardly of said deflector means whereby cooling air is directed by said deflector means across said condensEr device and is prevented by said deflector means from recirculating across said condenser device.

2. The combination described in claim 1 in which the inlet of said blower means is positioned adjacent the lower part of said passenger compartment and the outlet thereof opens into the upper part of said passenger compartment for causing circulation of conditioned air through said passenger compartment.

3. The combination described in claim 1 further including second blower means disposed to draw cooling air from said open space in front of said deflector means across said condenser device, thence to discharge said cooling air into said open space rearwardly of said deflector means.
