Abstract
An air conditioner includes an electric dust collector arranged between an evaporator and a heat shield plate. This electric dust collector includes a discharge electrode and a dust collecting electrode. The discharge electrode is applied with a positive polarity of high direct current voltage from a high voltage power source, while the dust collecting electrode is supplied with a negative polarity of high direct current voltage. Accordingly, the dust charged through plus electric discharge by the discharge electrode is attracted onto the dust collecting electrode or a casing thereof.
Claims4
An air conditioner, comprising:
- a housing having a back plate supported by a mount member and air intake port and an air outlet port:
- a heat exchanger arranged within said housing:
- an electric dust collector arranged between said heat exchanger and said back plate and having a discharge electrode and a dust collecting electrode;
- a high voltage power source for supplying a first polarity of a high direct current voltage to said discharge electrode and a second polarity of a high direct current voltage to said dust collecting electrode;
- and
- wherein said dust collecting electrode has a heater coated with a catalyst for effecting oxidation and decomposition, a heat shield plate provided in the vicinity of said back plate to field heat from said heater, and said dust collecting electrode being positioned between said heat exchanger and said heat shield plate.
