In the air conditioner of the present invention configured as described above, when the circulation fan 50 is driven and a voltage is applied to the discharge section 20, the contaminated air A in the atmosphere flows through the suction port 12 into the main body of the air conditioner. The dust in the air A is charged by the corona discharge generated in the discharge electrode plate 24 and the discharge counter electrode plate 28rM, and this air A is supplied to the downstream dust collecting section. When passing 30,
Only air that has been purified by collecting dust on the opposite electrode of the dust collecting electrode plate 32 or the charged filter 36 is supplied to the heat exchanger 40, and after being adjusted to a predetermined temperature by the heat exchanger 40, the air is purified. The heated and temperature-controlled air B is circulated by a circulation fan 5.
0 is supplied into the room.

[Effects of the Invention] As explained above, according to the air conditioner of the present invention, contaminated air is sequentially removed from the suction port toward the discharge port in the air flow path provided in the air conditioner main body. A discharge section that charges dust by corona discharge, a dust collection section that collects the dust charged in this discharge section, and a dust collection section that supplies only the air purified by the discharge section and dust collection section to a predetermined temperature. Since it is composed of a heat exchanger for adjustment and a circulation fan that supplies clean and temperature-controlled air to the indoor side, the following effects can be obtained.

■Air purification and temperature control can be performed simultaneously and easily in the same unit.

■Easy to install and install, making effective use of space.

■Since the temperature is adjusted after the air is purified in advance, the heat exchanger does not get dirty, preventing a decrease in efficiency due to dirt, and increasing the service life of the heat exchanger.

■Since pre-purified air is supplied to the heat exchanger, there is no risk that the air purifier will be harmed by condensed water and can be used safely.

■The discharge section that cleans the air through corona discharge, especially the discharge return electrode, has a high aperture ratio, so there is little pressure loss, reducing the burden on the circulation fan, and making less noise.
