The present invention relates to an indoor air purification system, and more particularly, to a prefabricated panel which is used as a partition or wall attachment device in an interior and has an exhaust passage therein and an air discharge port, and a purification device for purifying and discharging air. Inhalation of the air through the intake of the ceiling to purify the air is discharged through the air outlet of the prefabricated panel, so as not to install an air purifier in each compartment in the space having a compartment, Ultra-fine dust, which enables low-cost air purification and convection between air in the upper floor and air in the lower floor, resulting in energy savings and quick air quality improvement. The indoor air purification system using the prefabricated panel for purification .

At present, the attention warning of ultra-fine dust is rapidly increasing, which seriously affects the respiratory and eye health. Therefore, it is recommended to wear a dust mask that can limit outdoor activities or going out, or to block ultra-fine dust if inevitable.

However, even in the indoor, due to the bad air quality outside, the ventilation can not be frequently performed, and pollution caused by fine dust cannot be avoided, and thus, the home is equipped with an air cleaner to prepare for the fine dust.

However, in the case of such an air cleaner, in many spaces, such as offices, the space has to be installed for each partitioned space, so that an excessive installation cost may occur compared to the effect.

Accordingly, air purification systems using partitions that perform air purification of partitioned indoor spaces without having an air cleaner for each partitioned space have been provided. For example, Korean Patent No. 10-073077 discloses an interior space of a partition. Provided is a partition provided with an air purifying apparatus for performing indoor air purification by providing an air purification system.

However, in the above-described prior art, since the air purification module is provided for each partition, the price of the partition increases.

In addition, a system purifier for purifying and discharging air in a predetermined space by installing an air purifier in a ceiling or inside a wall has been developed, but in this case, the thickness of the vertical wall where an air discharge port through which the purified air is discharged is formed is thick. There is a problem that the overall cost is increased due to the installation of the inspection port for their inspection. In addition, in the case of installing the purification device in the ceiling or wall of the building or the building already in use, there is a problem in that the installation cost is increased because a work for forming the air outlet on the vertical wall is required. That is, in the existing system purifier, as the duct is disposed inside the vertical wall, the thickness of the vertical wall has to be thickened to more than 250 mm to secure the duct installation space, and there is a problem in that it cannot be moved as a fixed wall.

Can be. At this time, since the prefabricated panel 60 is thin, it is possible to install an air purification system without a separate wall construction, and to reduce the thickness of the wall itself.

The indoor air sensor unit 70 is configured to detect the pollution degree of the air introduced from the room and output to the control unit 90, the external air sensor unit 80 detects the pollution degree of the air introduced from the outside to the control unit ( 90).

Specifically, as shown in Figure 3, the indoor air sensor unit 70, the fine dust detection unit 71 for detecting the amount of fine dust and ultra-fine dust contained in the indoor air, and included in the indoor air TVOC detection unit 72 for detecting the total amount of organic compounds, formaldehyde detection unit 73 for detecting the amount of formaldehyde contained in the indoor air, and carbon monoxide detection unit for detecting the amount of carbon monoxide contained in the indoor air 74 and a carbon dioxide detector 75 for detecting the amount of carbon dioxide contained in the indoor air, and a sensor controller 76 for transmitting a detection signal to the controller 90. In addition, the external air sensor 80 is a fine dust detection unit 81 for detecting the amount of fine dust and ultra-fine dust contained in the outside air, and the carbon monoxide detection unit for detecting the amount of carbon monoxide contained in the outside air 82 and a carbon dioxide detector 83 for detecting the amount of carbon dioxide contained in the external air and a sensor controller 85 for transmitting a detection signal to the controller 90.

The control unit 90 controls the driving of the purifier 40, and compares the indoor air pollution degree information detected by the indoor air sensor unit 70 and the external air pollution degree information detected by the external air sensor unit 80. , Selective opening and closing of the flow path through the intake inlet 32 or the outside air inlet 3310 by the opening and closing door 31 of the internal and external air selection supply valve unit 30 so that the air of the low pollution degree is introduced into the room.

The controller 90 compares the pollution degree detected by the fine dust detector 71, the TVOC detector 72, and the formaldehyde detector 73 of the indoor air sensor unit 70 with the reference value to purify the purified air. By controlling the blower 44 of the device 40, the degree of pollution of the indoor air is reduced. Accordingly, the fine dust filter 41 of the blower 40 removes 99.99% or more of fine dust and ultrafine dust, and the purification filter 42 removes 80% or more of the organic compound and formaldehyde. . However, since it is impossible to reduce carbon monoxide and carbon dioxide by using the fine dust filter 41 and the purification filter 42, the outside air is supplied to the purification device 40 through the internal / external air selection supply valve unit 30 and ventilated. To be done.

In addition, the control unit 90 divides the pollution degree detection value into good, caution, bad, and very bad by comparing with the reference value, and operates the blower 44 to circulate the air in the case of caution or higher, and the worse the air quality. By operating the blower 44 at a higher speed, the circulation of the air is made faster, thereby improving the quality of indoor air.

In addition, the control unit 90 compares the contamination detection value detected by the fine dust detection unit 81 of the external air sensor unit 80 with a reference value only when the amount of fine dust and ultrafine dust of the external air is less than or equal to the reference value. By supplying air to the purifier 40, the amount of fine dust and ultrafine dust contained in the indoor air can be reduced. And, if the amount of carbon monoxide or carbon dioxide contained in the outside air is above a certain value, by blocking the inflow of outside air so that the air circulates only in the room to prevent the increase in the amount of carbon monoxide and carbon dioxide contained in the indoor air.

Indoor air purification system using the ultra-fine dust purification prefabricated panel of the present invention described above to replace the separate air conditioning device for the air purification, to install a partition for the indoor compartment or to install the prefabricated panel 60 attached to the pre-installed wall surface By doing so, it becomes possible to perform high efficiency air purification at low cost.
