In an air conditioning apparatus, the refrigerant discharged from a compressor of an outdoor unit is passed through an outdoor heat exchanger, the refrigerant having passed through the outdoor heat exchanger is passed through an indoor heat exchanger of an ambient air-conditioning unit and the refrigerant having passed through the indoor heat exchanger is returned to the compressor to cool the whole space in the room. At the same time, the refrigerant discharged from the compressor is passed through the outdoor heat exchanger, the refrigerant having passed through the outdoor heat exchanger is passed through indoor heat exchangers of a plurality of personal air-conditioning units and the refrigerant having passed through the indoor heat exchangers is returned to the compressor to separately cool the discrete spaces in the room. At the time of cooling, the processes for the sensible heat load and latent heat load are effected in the in the indoor heat exchanger of the ambient air-conditioning unit and only the process for the sensible heat load is effected in the indoor heat exchanger of each of the personal air-conditioning units.

Air conditioning apparatus having ambient air-conditioning unit and a

Two or more indoor units are provided on ceiling and floor of a room. Each of the indoor units has an air heat exchanger for cooling indoor air, and a drain pan for catching drainage produced by the air heat exchanger. A drain pipe is provided in the ceiling and under the floor. The, drainage in each of the drain pans flows into the drainage pipe. The drain in the drain pipe is carried and discharged outdoor by a drain carrying unit.
