Abstract
A room air conditioner mounted on an external building wall, comprising an indoor unit, an outdoor unit and an interface unit. The indoor unit includes an indoor cabinet having a suction opening and outlet port for indoor air, an indoor heat exchanger, and an indoor fan. The outdoor unit includes an outdoor cabinet having a suction opening and outlet port for fresh air, an outdoor heat exchanger, an outdoor fan and a fan motor which engages the outdoor and indoor fans. The interface unit is mounted in the external building wall and includes a fan drive shaft engaged at the first end by the fan motor in the outdoor cabinet and engaging the indoor fan. The room air conditioner produces less noise compared to room air conditioners of the prior art, while requiring a significantly smaller exterior wall opening for installation, at the same time providing the flexibility to permit the introduction to the room of fresh outside air, the humidification of heated air in the heating mode, and the cooling or heating of air in more than one room.
