PURPOSE:To send out clean air free from a bad small by forming a bypass air channel for returning part of air passing through a heat exchanger to an air channel between an air intake port and the heat exchanger, by providing an ozonizer and a fan in the bypass air channel and by providing an ozone dissolving device in front of an air blowoff port. CONSTITUTION:Air in a room is taken into an air channel 3 from an air intake port 1 by a fan 5 and passed through a heat exchanger 4 to be heated or cooled. A prescribed quantity of the air is introduced into a bypass air channel 10 from a suction port 12 by a fan 14. The introduced air is turned by an ozonizer 13 into air containing ozone, and this air is returned from a discharge port 11 to the air channel 3 and mixed with the air introduced from the air intake port 1 in a labyrinth space 8, so as to be air containing ozone uniformly. The air containing ozone decomposes and exterminates an air-pollution substance, mold and germs sticking to or being present to in the air channel 3 and the heat exchanger 4. After passing through the heat exchanger 4, the air containing ozone is dissolved by an ozone dissolving device 6 and blown off from an air blowoff port 2. |
