Description

TECHNICAL FIELD [0001] The present invention relates to an air conditioning system and a control method thereof,

The present invention relates to a vehicle air conditioning system and a control method thereof, and more particularly, to an air conditioning system and a control method thereof that can generate ozone through an electric dust collection unit to sterilize and deodorize an air conditioning case and a vehicle interior. And a control method thereof.

The interior of the vehicle is narrow and airtight, and the contamination of the interior of the vehicle is further exacerbated by fine dust and various pollutants in the city. Particularly, since the current vehicle penetration rate continues to increase, and the time in which the user is inside the vehicle also increases, research for maintaining the comfort inside the vehicle continues.

As an example of purifying the interior of a vehicle, air purifiers for automobiles for sterilizing microbes captured in the air purification process and allowing cleaner air to enter the room are disclosed in Korean Patent Application No. 10-2004-97758. 1, the air cleaner for a vehicle includes a case 50 having a suction port 51 and an outlet port 52, a first air cleaner 50 installed at the rear of the air suction port 51 for collecting foreign matter or dust, A filter 60 installed in front of the outlet 52 of the case 50 and a static eliminator 70 for adsorbing fine dust using electric discharge and a photocatalyst disposed in front of the outlet 52 of the case 50 to decompose the organic material, And an ultraviolet lamp 80 installed between the electrostatic dust precipitator 70 and the second filter 90 to activate the photocatalyst of the second filter 90.

In the conventional air purifier for vehicles, the harmful microorganisms are sterilized using the photocatalyst activated by the ultraviolet rays of the ultraviolet lamp, and odor generation factors are removed through decomposition of organic materials. The air introduced through the inlet port 51 of the case 50 is filtered while passing through the first filter 60. The first filter 60 mainly filters dust having a large particle size. The primary filtered air flows into the electrostatic precipitator 70. When power is supplied through the power supply unit 73, the fine dust particles charged by the discharge electrode 71 are attracted to the dust collecting electrode 72. [ Therefore, the fine dust that has passed through the first filter is removed by the electrostatic precipitator 70. Microbes such as bacteria and fungi contained in the air are sterilized by ultraviolet rays irradiated from the ultraviolet lamp 80 while the air passing through the electrostatic dust precipitator 70 flows to the second filter 90. In addition, the second filter 90 decomposes organic matter such as ammonia by using the photocatalyst activated by the ultraviolet light emitted from the ultraviolet lamp 80, thereby preventing odor from being generated, The harmful microorganisms such as fungus and bacteria are sterilized and removed. Therefore, the air discharged through the outlet 52 of the case 50 is in a clean state in which dust and harmful microorganisms are removed.

That is, the air cleaner for vehicles uses a variety of filters collecting fine dust to purify indoor air of the vehicle, or a combination of ultraviolet lamps for sterilization.

However, the filter for collecting fine dust mainly uses a particulate filter to filter out particles having a specific diameter or more, a form for collecting bacteria, fungi and odor generating factors by using an activated carbon filter, And discharging and then collecting.

The first and second type filters need to be replaced as the dust is removed by trapping, while the third type of dust collecting filter does not need to be replaced and the small size particles can be effectively removed There are advantages to be able to.

2 is a view for explaining the dust collection of the electrostatic dust precipitator 70 which is a filter of the electrostatic dust collecting type and includes a discharge plate 71a for charging the introduced dust D by corona discharge and a discharge pin 71b A charging unit 71 and a dust collecting unit 72 for collecting the charged dust D 'through the charging unit 71. [

In the electrostatic precipitator of the type shown in FIG. 2, electromagnetic noise and ozone are generated at the sharp ends of the discharge fin as the corona discharge is charged. Electromagnetic noise interferes with the operation of various devices inside the vehicle, and ozone has a problem that separate means for removing water and ozone from the human body must be provided.

Further, when the blower is operated in a state where the power of the electrostatic dust precipitator is not supplied, the dust adhering to the wall surface of the electrostatic dust collecting filter may be detached and supplied to the vehicle interior.
