Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a compact fan filter unit having an antibacterial function and a clean air-

The present invention relates to a fan filter unit and a clean air conditioning system using the fan filter unit. More particularly, the present invention relates to a fan filter unit having a compact structure by arranging a blower and a filter in a vertical structure, The present invention relates to a compact fan filter unit having an antibacterial function and a clean air conditioning system using the same, which has a structure capable of effectively coping with airborne bacteria and viruses.

In general, a space such as a workplace where production of high-precision electronic parts such as semiconductors is performed, a workshop where food or medicine is produced, or an operation room where a surgical operation is performed must be kept constant in temperature and humidity in accordance with working conditions, It is necessary to keep the clean state by removing fine dust in the air.

Therefore, the work that is sensitive to the suspended substances such as temperature, humidity, and fine dust as described above is performed in a clean room.

The clean room is provided with the temperature and humidity controlled air through the air conditioner to always maintain a constant temperature and humidity. In the ceiling of the clean room, the air-conditioning air provided from the air conditioner is finally filtered and ejected into the inside of the clean room A clean air conditioning unit is installed.

Fig. 1 shows the structure of a conventional clean air-conditioning unit.

The clean air-conditioning unit shown in FIG. 1 is disclosed in Korean Utility Model Publication No. 0405156. The structure of a conventional clean air-conditioning unit will be described with reference to FIG.

The conventional clean air conditioning unit comprises a suction chamber 10, an exhaust chamber 20, a blower 30, and a filter 40.

The air-conditioning air and the circulating air are introduced into the suction chamber 10 by the operation of the blower. The air-conditioning air and the circulating air thus introduced enter the exhaust chamber (not shown) formed on the side surface of the suction chamber 10 20, and then is blown into the inside of the clean room through the filter 40 provided in the exhaust chamber 20.

For reference, the air-conditioning air is air whose temperature and humidity are controlled by the air-conditioning equipment, and the circulating air is air circulated by being discharged from the clean room.

In the conventional clean air-conditioning unit thus structured, the air-conditioning air and the circulating air flow in a direction orthogonal to each other or in a direction opposite to each other, and the flows of the two fluids collide with each other. And the flow of the fluid is not smooth, resulting in a problem that the cleanliness of the air and the distribution of the temperature and humidity become incomplete.

Further, when the air-conditioning air pressure and the circulating air pressure are not balanced, there is a problem that the backwash phenomenon occurs due to the air being pushed to one side.

Also, since the conventional clean air-conditioning unit as described above can not configure the suction chamber and the exhaust chamber together due to the volume of the sirocco fan constituting the blower, and the exhaust chamber is formed in the side portion of the suction chamber, the area occupied by the clean air- .

FIG. 2 is a plan view showing a structure in which a clean air-conditioning unit and an unshielded lamp are installed on a ceiling of a conventional operating room.

In FIG. 2, eight clean air conditioning units BFU are centrally located at a central portion where the operation table T is located. Each of the clean air conditioning units includes a suction chamber 10, And an exhaust chamber (20).

On the other hand, in the ceiling of the operating room, an unshaded lamp (L) is installed on all sides to prevent the generation of shadows during surgery.

However, when the suction chamber and the exhaust chamber are partitioned in the horizontal direction as in the conventional clean air-conditioning unit, since the area occupied by the clean air-conditioning unit is inevitably required to be installed far from the operation table, There is a problem that the effect is reduced.
