- the rod-shaped discharge electrode (31) is arranged along the air inflow surface of the heat exchanger (20) while being orthogonal to the air flow. For this reason, the discharge electrode (31) can be compactly arranged in the air passage (15), and the air conditioner (10) can be further reduced in thickness.
- the streamer discharge (60) is developed toward the tip force counter electrode (32) of the rod-shaped discharge electrode (31). In this way, the electric field density in the discharge region increases, and the amount of active species generated can be increased. For this reason, the decomposition performance of the component to be treated in the air conditioner (10) can be further improved.
- the discharge electrode (31) and the counter electrode (32) are arranged substantially in parallel.
- the catalyst unit (40) is arranged between the discharge unit (30) and the heat exchanger (20). For this reason, the catalytic unit (40) can be activated with active species to further improve the decomposition performance of the components to be treated. Further, since the adsorbent is supported on the catalyst unit (40), the low concentration component to be treated remaining in the air can be adsorbed and removed by the adsorbent.
- the pre-filter (41) is arranged upstream of the discharge unit (30). For this reason, adhesion of dust to the discharge unit (30) can be prevented. Therefore, stable streamer discharge can be performed in the discharge unit (30) over a long period of time.
- the prefilter (41) since the prefilter (41) is provided, it is possible to prevent dust from adhering to the heat exchange (20), and thus it is possible to prevent a decrease in the heat exchange rate between the heat exchange (20) and the air to be treated.
- the discharge electrode (31) is formed in a plate shape, and one side thereof has a sawtooth shape.
- the counter electrode (32) is disposed in the air passage (15) in a posture substantially parallel to the discharge electrode (31).
- the discharge electrode (31) and the counter electrode (32) are arranged along the air inflow surface of the heat exchanger (20), not shown, while being orthogonal to the air flow.
- the serrated discharge electrode (31) and the counter electrode (32) are arranged along the air inflow surface of the heat exchanger (20) perpendicular to the air flow, so that the discharge part (30) Can be stored compactly in the air passage (15), and the air conditioner (10) can be made thinner.
- the needle-like discharge electrode (31) is supported on one side surface of the support plate (33) having an L-shaped vertical section.
- the discharge electrode (31) is composed of a rod-shaped body and a conical protrusion formed at the tip of the body.
- the counter electrode (32) is disposed in the air passage (15) in a posture substantially parallel to the discharge electrode (31).
- the discharge electrode (31) and the counter electrode (32) are arranged along the air inflow surface of the heat exchanger (20) (not shown) while orthogonal to the air flow, as in the above embodiment. ing.
- the component to be treated can be sufficiently removed while downsizing the air conditioner (10).
- the needle-like discharge electrode (31) and the counter electrode (32) are arranged so as to be perpendicular to the air flow and along the air inflow surface of the heat exchange (20).
- the air conditioner (10) can be compactly stored in the air passage (15), and the air conditioner (10) can be made thinner.
- the discharge unit (30) of Modification 3 shown in FIG. 6 includes an insulating cover (35), a discharge base (34), and a rod-shaped discharge electrode (31), as in the above embodiment.
- the plate-like counter electrode (32) is not provided, and the tip of the discharge electrode (31) faces the heat exchange (20).
- the heat exchanger (20) is composed of conductive aluminum as a main material, and is electrically connected to the negative electrode side (ground side) of the DC power source (50).
- the heat exchanger (20) is configured to also serve as the counter electrode (32) of the above embodiment.
- the streamer discharge is performed by using the heat exchange (20) as the counter electrode (32) and directing the heat exchange ⁇ (20) from the discharge electrode (31). I have to. For this reason, it is not necessary to provide the counter electrode (32) separately, and the number of parts of the air conditioner (10) can be reduced. In addition, the air conditioner (10) can be reduced in size and thickness by the space for installing the counter electrode (32).
- the prefilter (41) is provided as a collecting means for collecting dust in the air.
- an electrostatic precipitator or any other precipitator instead of this, place an electrostatic precipitator or any other precipitator.
- the heat exchanger (20) that only controls the temperature of the air to be treated is provided as an air conditioning unit.
- an adsorbent that adsorbs and desorbs moisture in the air and a humidifier that imparts moisture to the air may be provided.
- the present invention is useful for an air conditioner that cleans the air to be treated.
