A room air-conditioner (10) for installation into a pre-constructed aperture through a building wall (34) has a depth substantially equivalent to the wall thickness and is adapted to stand at floor level within said aperture with front and rear covers (11, 12) flush with internal and external surfac

A room air-conditioner (10) for installation into a pre-constructed aperture through a building wall (34) has a depth substantially equivalent to the wall thickness and is adapted to stand at floor level within said aperture with front and rear covers (11, 12) flush with internal and external surfaces of the wall, respectively. The necessary compact design is achieved by stacking the components vertically within the air-conditioner whereby the condenser coil (16) is at the bottom and air for the condenser is drawn in and extracted from the rear whereas the evaporator coil (22) is towards the top and air for the evaporator is drawn in and extracted from the front. Fans (19, 24) for each coil are arranged coaxially and driven by a single motor (21). The coils have a C-shaped configuration. Condensate is collected from the evaporator coil in containers (29, 31) and is used to cool refrigerant pipes (30, 32) entering and leaving the condenser coil. The condensate may also be sprayed in a fine mist over said condenser coil.
