Abstract: 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.

Abstract: A refrigeration cycle has a compressor, an outdoor rotary-type heat exchanger, a motor-operated expansion valve, and an indoor rotary-type heat exchanger which are sequentially connected to each other to circulate a refrigerant. A tank is set in a connected state or a non-connected state with respect to a refrigerant discharge side of the compressor. A detector detects at least a pressure at one side of each of the exchangers. A first controller sets the tank in a non-connected state when a normal operation of an air conditioner is to be started, and controls the capacity of the compressor, the rotational speed of the exchangers, and the opening degree of the valve in accordance with an air-conditioning load, thereby performing the normal operation of the air conditioner.
