Abstract: An air conditioning system includes an air-conditioner casing, an air blower, a cooling heat exchanger, a heating heat exchanger, and a bypass passage. An electric motor of the blower has a rotating shaft that extends along a rotating shaft axis. An impeller of the blower suctions air from one side of the impeller along the rotating shaft axis to blow air in a radial direction of the impeller. The bypass passage causes cold air to bypass the heating heat exchanger. The air blower is located downstream of the cooling heat exchanger and the heating heat exchanger in a flow direction of air. The cooling heat exchanger and the heating heat exchanger are arranged in parallel with each other. The air blower is positioned on an imaginary extension of the heating heat exchanger. The rotating shaft is disposed in parallel with the heating heat exchanger.

Abstract: An air conditioning system for conditioning air in a room includes an air-conditioner casing, an air blower, a cooling heat exchanger, and a heating heat exchanger. The air-conditioner casing causes air to flow toward the room. The air blower includes an electric motor and an impeller rotated by the electric motor to generate air flowing toward the room. The cooling heat exchanger is provided in the air-conditioner casing for cooling air. The heating heat exchanger is provided in the air-conditioner casing for heating air. The air blower is provided downstream of the cooling heat exchanger and the heating heat exchanger in a flow direction of air. Air in the room is conditioned based on cold air cooled by the cooling heat exchanger and hot air heated by the heating heat exchanger. The electric motor is provided outside the air-conditioner casing and is cooled by room air.
