<P>PROBLEM TO BE SOLVED: To provide an air conditioner which is excellent in thermal efficiency without using a large amount of underground water and is capable of performing the temperature/humidity control or air cleaning of a building while achieving energy saving and the alleviation of an environmental load. <P>SOLUTION: The air conditioner is configured as follows. The air conditioner 20 includes: an almost cylindrical heat exchange tank 21 for storing cold water or hot water with predetermined temperature; and a double-pipe structure consisting of an outer cylindrical pipe 22 and an inner cylindrical pipe 23 coaxially erected at the center of the heat exchange tank. The air conditioner: performs heat-exchange of indoor air to be supplied to an air channel formed between the outer cylindrical pipe and inner cylindrical pipe having the double-pipe structure, with cold water or hot water in the heat exchange tank; and discharges the air toward the inner cylindrical pipe. <P>COPYRIGHT: (C)2013,JPO&INPIT |
