In preparation for biochemical terror, the building's air intake is recommended to be installed above a certain height above the ground to prevent terrorists' access and inflow of poison gas.

However, if biochemicals have already been spread in certain areas of the building, the system to prevent the spread of these biochemicals is inadequate. In the case of biological terrorism, it is important to respond early because symptoms do not appear and are left to seal, but this requires a system for early detection of pollutants.

In addition, in the case of chemical terrorism, if a pollutant is in a building, it must be quickly exited without passing through the contaminated place.However, if a pollutant is sprayed in an area of the building, the pollutant may be further moved to another area by the air conditioning of the building itself. It is likely to spread quickly, resulting in greater casualties.

2 is a flow chart illustrating a control method for preventing a risk due to biochemicals in a building control system according to an embodiment of the present invention.

Hereinafter, with reference to the accompanying drawings, a building control system and method for preventing the risk due to biochemicals according to the present invention will be described.

1 is a view showing a schematic configuration of a building control system according to an embodiment of the present invention.

Referring to FIG. 1, the building control system according to the present invention includes a building air conditioner, an air conditioner 100, a conductivity detector 120, a microbial measurement unit 140, and a central controller 160.

The building air-conditioning department has a division space (10-1,10-2, ..., 10-n) where each occupant of the building resides, and each division space (10-1,10-2, ..., 10-n) Air supply duct 40 having a plurality of air supply guide ducts (45) branched into the inside, and the air supply duct 40 in each division space (10-1, 10-2, ..., 10-n) On the exhaust duct 50 and the air supply duct 40, which are separately installed and have a plurality of exhaust guide ducts 55 branched into each division space 10-1, 10-2,..., 10-n. It is provided on the air supply damper 30 to adjust the opening degree of the duct, and the exhaust damper 20 is provided on the exhaust duct 50 to adjust the opening degree of the duct.

The air conditioner 100 is installed between the air supply duct 40 and the exhaust duct 50, and the air supply duct 40 and the exhaust air are separated into the respective spaces 10-1, 10-2, ..., 10-n. It is connected via the duct 40. The air conditioner 100 includes an air filter 101 for filtering dust and bacteria, a cooling coil 103 for cooling the exhaust air introduced from the exhaust duct 50 by contact with a refrigerant body, and a heating coil for heating the air. 105, and a supply fan 107 which sends air passing through the cooling coil 103 to the room through the air supply duct 40.

Part of the air exhausted by the exhaust fan 60 and air coming in from the outside pass through the air filter 101 to filter dust and bacteria. The filtered air is lowered in temperature and humidity while passing through the cooling coil 103, and is heated while passing through the heating coil 105. In this case, when the air needs to be humidified, the air conditioner 100 further includes a spray device (not shown). The air passing through the air filter 101, the cooling coil 103, and the heating coil 105 is supplied to each division space 10-1, 10-2, ..., 10- of the building by the supply fan 107. n) is sent.

At this time, since the air passing through the cooling coil 013 is air that is hotter than the cooling coil 103, condensation is generated while passing through the cooling coil 103, and condensate is generated in the condensate. Substances will also be included.

If the main refrigerator (not shown) is not operated, such as in a special case of pure heating, only a separate cooling coil is operated to generate a condensed water and to operate an auxiliary refrigerator such as a heat pump including a reheat coil to reheat it. It is preferable.

As the air supply damper 20 is opened and closed, air is supplied and blocked to each division space 10-1, 10-2,..., 10-n through the air supply duct 40. Similarly, the air in each division space 10-1, 10-2,..., 10-n is exhausted and blocked by the exhaust damper 30 by opening and closing.

The conductivity detector 120 detects the electrical conductivity of the condensed water generated by the cooling coil 103. In more detail, a drain plate 109 in which condensed water generated when air passes through the cooling coil 103 is installed below the cooling coil 103. After the condensate accumulated in the drain plate 109 is transferred to the conductivity detecting unit 120, the electrical conductivity of the condensate is continuously detected in the conductivity detecting unit 120.

Electrical conductivity is the inverse of the intrinsic electrical resistance, also called conductivity, and the unit is written S and reads Siemens. The higher the conductivity of the condensate, the greater the electrical conductivity, and the higher the purity, the lower the electrical conductivity. In other words, condensate in which contaminated air is condensed contains contaminants in the air, and the more the contaminants, the higher the electrical conductivity of the condensate.

Since the device for measuring such electrical conductivity is a known technique as described in the Republic of Korea Patent Publication No. 10-0741042 which is a patent document, the detailed structure may refer to the document.

The central controller 160 receives the electrical conductivity detected by the conductivity detector 120 and controls to stop the operation of the air conditioner 100 when the electrical conductivity is greater than a preset reference value. That is, when the electrical conductivity of the condensate is greater than the preset reference value, the central controller 160 stops the supply fan 107 so that each zone 10-1, 10-2, ..., 10-n of the building is stopped. To ensure that no more air is supplied. This can prevent contaminated air from certain areas of the building from being supplied to other areas.

Alternatively, the central controller 160 stops air conditioning of the building air conditioning unit by closing the air supply damper 30 and the exhaust damper 20. That is, the central control unit 160 controls the air supply damper 30 and the exhaust damper 20 to be closed in the building air conditioning unit, thereby allowing air to be separated into each division space 10-1, 10-2, ..., 10-n. Is controlled so that air is not supplied or exhausted from each of the division spaces 10-1, 10-2, ..., 10-n.

The microbial measurement unit 140 cultures the microorganisms from the condensed water from which the electrical conductivity is detected by the conductivity detection unit 120, and then collects a sample to measure and output the microbial value. In more detail, when the electrical conductivity detected by the conductivity detector 120 is greater than the preset reference value, the central controller 160 controls the microbial measurement unit 140 to measure the microbial value of the condensate.

The microbial measurement unit 140 receives a portion of the condensate from the conductivity detection unit 120, and then cultures the microorganisms to collect a sample. There are various methods of collecting a sample, and in the present invention, taking a sample by allowing the cultured microorganism to adhere to the antibody with the fluorescent dye. When light is emitted to the collected sample, the light is emitted secondarily from the fluorescent dye. At this time, the microbial value is measured by measuring the size of the light emitted second.

The central control unit 160 controls to resume operation of the air conditioner 100 when the microbial value measured by the microorganism measuring unit 140 is equal to or less than a predetermined reference value. That is, when the microbial value of the condensate is less than or equal to the preset reference value, the supply fan 107 is operated to circulate air to each of the divided spaces 10-1, 10-2, ..., 10-n of the building. .

On the other hand, when the microbial value measured by the microbial measurement unit 140 is greater than the preset reference value, the central control unit 160 displays the microbial value numerically. In this case, the central control unit 160 sounds an alarm so that the building manager can check the numerical value, or causes an alarm sound to be generated in the whole building so that people staying in the building can know.

2 is a flowchart illustrating a control method for preventing a risk due to biochemicals in a building control system according to an embodiment of the present invention.

According to FIG. 2, first, an electrical conductivity of condensate detected by the conductivity detection unit 120 is received (S200). That is, the conductivity detecting unit 120 detects electrical conductivity by transferring condensed water accumulated in the drain plate 109 installed under the cooling coil 103 of the air conditioner 100. At this time, the electrical conductivity is continuously detected by the conductivity detector 120 and transmitted to the central controller 160.

When the electrical conductivity transmitted from the conductivity detection unit 120 is greater than the preset reference value (S210-Y), the central control unit 160 stops air conditioning of the building air conditioning unit (S210). That is, the central control unit 160 stops the operation of the supply fan 107, so that the air conditioner 100 is not supplied to each division space 10-1, 10-2, ..., 10-n. To control. Alternatively, the central controller 160 may stop air conditioning of the building air conditioning unit by closing the air supply damper 30 and the exhaust damper 20.

Then, the central control unit 160 controls the microbial measurement unit 140 to measure the microbial value of the condensate (S230). Here, the microbial measurement unit 140 collects a sample by culturing the microorganisms for a part of the condensate, and then attached to the antibody with the fluorescent dye. And, when the light is emitted to the sample collected, by measuring the size of the light emitted second from the fluorescent dye, the microbial value is measured and output.

When the microbial value measured by the microbial measurement unit 140 is greater than the predetermined reference value (S240-Y), the central control unit 160 outputs the microbial value as a number (S250). At this time, the central control unit 160, when the microbial value is output as a number, so that the alarm or alarm sounds together to cope with the dangerous situation.

If it is determined that the microbial value measured by the microbial measurement unit 140 is equal to or less than a predetermined reference value (S240-N), the central control unit 160 controls to resume operation of the air conditioner 100 (S260). That is, the central controller 160 operates the supply fan 107 to control the air conditioner 100 so that air is supplied to each division space 10-1, 10-2,..., 10-n.

By the above process, when the biochemical material is sprayed in a predetermined area of the building, by detecting it and stopping the air conditioning of the building air conditioning unit, it is possible to prevent the biochemical material from spreading to other areas. In addition, it is possible to quickly determine the contamination situation by outputting the numerical value of the contamination.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
