<P>PROBLEM TO BE SOLVED: To provide an air conditioning apparatus that can raise a body temperature without feeling chill in the air, for example, when a body is cooled by blowing wind having a temperature equal to or above the body temperature toward a person without deteriorating the coefficient of performance (COP) of a heat pump cycle. <P>SOLUTION: The air conditioning apparatus includes: a compressor for compressing a gaseous refrigerant; at least two condensers connected serially to each other where a heat exchange is carried out between the compressed refrigerant and indoor air; an expansion part for expanding the refrigerant discharged from the condensers; and an evaporator where the heat exchange is carried out between the refrigerant discharged from the expansion part and outdoor air. In the condensers, a first condenser carries out the heat exchange between the indoor air and the compressed gaseous refrigerant, and in the condensers, a second condenser carries out the heat exchange between the indoor air and the refrigerant in a gas-liquid mixed state of the gas and liquid discharged from the first condenser. When the person exists indoors, the indoor air subjected to heat exchange in the first condenser is blown toward the indoor person at a temperature equal to or above a prescribed temperature and the indoor air subjected to heat exchange in the second condenser is blown to a space where the person does not exist indoors. <P>COPYRIGHT: (C)2013,JPO&INPIT |
