Deformed example 2

In the discharge cell (30) of the second modification shown in FIG. 5, a needle-shaped discharge electrode (31) is supported on one side of a support plate (33) having an "L"-shaped vertical section. The discharge electrode (31) is composed of a rod-shaped trunk and a conical protrusion formed at the tip of the trunk. On the other hand, the counter electrode (32) is arranged in the air passage (15) substantially parallel to the discharge electrode (31). In addition, the discharge electrode (31) and the counter electrode (32) are perpendicular to the air flow direction and arranged along the air inflow surface of the heat exchanger (20), not shown, as in the above-mentioned embodiment. Then, when a voltage is applied from a DC power supply (50) to both electrodes (31, 32), streamer discharge (60) develops from the tip of the protrusion of the discharge electrode (31) to the counter electrode (32).

[0071] Also in this modification 2, since the streamer discharge (60) can gener...

Deformed example 3

The discharge unit ( 30 ) of Modification 3 shown in FIG. 6 is the same as the above embodiment, including an insulating barrier ( 35 ), a discharge base ( 34 ) and a rod-shaped discharge electrode ( 31 ). On the other hand, in this third modification, different from the above-mentioned embodiment, there is no plate-shaped counter electrode (32), and the top end of the discharge electrode (31) faces the heat exchanger (20). The heat exchanger (20) is mainly composed of conductive aluminum, and is electrically connected to the negative side (ground side) of the DC power supply (50). Furthermore, the heat exchanger (20) is configured to also serve as the counter electrode (32) of the above-mentioned embodiment. That is, once a voltage is applied from the DC power supply (50) to the discharge electrode (31) and the heat exchanger (20), a streamer discharge is developed from the top of the rod-shaped discharge electrode (31) to the surface of the heat exchanger (20). (60). Furthe...

Abstract

An electric discharge unit (30) and a heat exchanger (20) are arranged in an air path (15). In the electric discharge unit (30), a stick-like discharge electrode (31) and a plate-like opposed electrode (32) are arranged orthogonal to airflow and along the heat exchanger (20). When a voltage is applied to both electrodes (31, 32), streamer discharge occurs between the electrodes (31, 32), creating active species that decompose a component to be treated.

Description

technical field [0001] The invention relates to an air conditioner for conditioning the air to be processed, in particular to an air conditioner for purifying the air to be processed. Background technique [0002] Conventionally, air-conditioning apparatuses for air-conditioning indoor spaces such as general households have been known. Among such air conditioners, those having an air cleaning function are also widely known. [0003] For example, the air conditioner disclosed in Patent Document 1 is a so-called wall-mounted room air conditioner provided with an air cleaning function. In this air conditioner, an air passage for treated air is formed in a cabinet. The air passage is provided with a corona discharge unit for decomposing odor components and harmful components in the air (hereinafter referred to as components to be processed), and a heat exchanger for air conditioning. The corona discharge unit includes a pair of electrodes, and a power source that applies a pu...
