Abstract
An air conditioning apparatus with an air cleaning function. In the apparatus, an electric dust collector is provided in the air passage on the rear side of a heat exchanger. A heater for self-cleaning is combined with a dust collector electrode of the electric dust collector. A heat shield plate is combined with the heater. Air flow resistance is not increased although the dust collector electrode is plane in shape. An increase of air flow resistance caused by the use of the heat shield plate is also suppressed.
Claims12
An air conditioning apparatus with an air cleaning function, comprising:
- a heat exchanger;
- a casing whose inner space is partitioned by said heat exchanger, wherein one side of the partitioned inner space includes an air inlet and an incoming air passage while the other side thereof includes an air outlet and an outgoing air passage;
- an air discharging fan provided in the outgoing air passage;
- and
- an electric dust collector, including a heat shield plate for shielding heat arrayed substantially parallel to an air stream flowing through from the air inlet to the air outlet, a discharge electrode, and a dust collector electrode, provided in the outgoing air passage, wherein dust particles contained in air that is introduced through the air inlet and passes through said heat exchanger are charged by a discharge taking place between the discharge electrode and the dust collector electrode, and the charged dust particles are electrostatically attracted to the dust collector electrode.
An air conditioning apparatus with an air cleaning function, comprising:
- a casing of which at least a front side includes an air inlet and an air outlet located below the air inlet;
- a heat exchanger disposed within said casing while being confronted with the air inlet of said casing;
- a fan for introducing air through the air inlet, making it pass through said heat exchanger, and discharging it through the air outlet;
- and
- an electric dust collector in which dust particles contained in air passing through said heat exchanger are charged by corona discharge taking place between a discharge electrode and a dust collector electrode, and are electrostatically attracted to the dust collector electrode, wherein the electric dust collector includes a heat shield plate for shielding heat arrayed substantially parallel to an air stream flowing through from the air inlet to the air outlet and is provided between a rear side of said heat exchanger and an inner wall of said casing.
An electric dust collector used for an air conditioning apparatus with an air cleaning function, comprising:
- a combination of a discharge electrode and a dust collector electrode for causing a corona discharge therebetween to make dust particles electrostatically attract to the dust collector electrode by coulomb force;
- a heater for burning or thermally decomposing the dust particles attracted to the dust collector electrode;
- and
- a heat shield plate for shielding heat from the heater, said heat shield plate also serving as a mounting plate on which the discharge electrode and the heater are mounted.
