1 to 5, the intelligent integrated air conditioning system of fire associated with the underground composite commercial facility according to an embodiment of the present invention performs intelligent integration of air conditioning in connection with the fire occurrence of the underground composite commercial facility 10. The duct unit 110, the air supply unit 120, the exhaust unit 130, the cleaning dust collecting unit 140, the contaminated water treatment unit 150, the sensor unit 160, and the system controller 170. ).

The duct unit 110 includes an interlayer duct 111, an air supply duct 112, and an exhaust duct 113. Here, the interlayer duct 111 is installed for each floor of the underground composite commercial facility 10. The underground complex commercial facility 10 may correspond to an underground complex substation, but may correspond to various complex commercial facilities such as a complex shopping mall having a space underground.

The interlayer duct 111 may be installed on the ceiling of the floor space. The interlayer duct 111 introduces purified air supplied from the air supply duct 112 into the layer space through the inlet port, and sucks the contaminated air in the layer space through the inlet port and discharges the exhaust air to the exhaust duct 113. The inlet and the inlet of the interlayer duct 111 may be opened and closed by dampers, respectively.

In the case of a fire protection zone, such as a main transformer bay (Main transformer bay) 11, a damper of the interlayer duct 111 operates to block air inflow into the surrounding pressure chamber 11. After the inflow of air to the surrounding pressure chamber 11 is blocked, a halon of the extinguishing facility is injected into the surrounding pressure chamber 11 of the sealed space to remove oxygen from the sealed space to prevent fire spreading. Thereafter, the water of the fire extinguishing facility is sprayed into the surrounding pressure chamber 11 to allow the fire to initially enter.

The air supply duct 112 is connected to the interlayer duct 111 to supply outdoor air through the filter 116. The air supply duct 112 may have a shape in which a passage extends vertically. The air supply duct 112 sucks outdoor air through the upper air intake port and supplies the air duct 112 to the interlayer duct 111 through the air supply port.

The filter 116 is installed at the intake port of the air supply duct 112 to collect foreign substances in the outdoor air, and then discharges the purified air into the air supply duct 112. The filter 116 may include a roll filter, a hepa filter, a loofah filter, or the like.

A roll filter is a filter which winds a filter medium on a wide roll, and filters it in the form which winds up when a large amount of dust etc. adhere to a flowing air passage. The scrubber filter is a scrubber filter, which is excellent in filtration effect and easy to clean.

The filter 116 may be cleaned by the filter cleaning unit 117. Therefore, since there is no periodic replacement of the filter 116, it is possible to reduce the replacement cost and labor according to the replacement operation. The filter cleaning unit 117 injects the water mist into the filter 116 by using a water mist injector 118, and then sprays compressed air by the compressed air injector 119, thereby remaining of the filter 116. Can be configured to eliminate the enemy.

The water mist injector 118 may be configured to pump water stored in the water tank to the nozzle by a pump to spray the water mist through the nozzle. The water mist injector 118 of the filter cleaning unit may correspond to one of the water mist injectors 141 constituting the cleaning dust collecting unit 140. The compressed air injector 119 may be configured to inject air compressed by the air compressor through the nozzle.

The water mist injector 118 and the compressed air injector 119 may be controlled by the system controller 170. In the air supply duct 112, an air flow rate sensor 164 may be installed to measure the air flow rate of the air passing through the filter 116 from the intake port. The system controller 170 drives the filter 116 by driving the water mist injector 118 and the compressed air injector 119 when the measured air volume is determined to be less than or equal to the set air volume based on the air volume provided from the air volume sensor 164. It can be washed.

The exhaust duct 113 is connected to the interlayer duct 111 to discharge indoor air to the outside. The exhaust duct 113 may have a shape in which the passage extends vertically. The exhaust duct 113 sucks contaminated air from the interlayer duct 111 through the intake port and discharges it outward through the upper exhaust port.

The air supply unit 120 sucks outdoor air through the air supply duct 112 and sends the outdoor air to the interlayer duct 111. The air supply unit 120 may include air supply fans 121. The air supply fan 121 may be installed in a facility space provided for each floor to supply air from the air supply duct 112 to each floor space. The rotation speed of the air supply fan 121 may be adjusted by the air supply fan inverter 122. The air supply fan inverter 122 may be connected to the sensor unit 160 and the system controller 170 and controlled through a network.

The exhaust unit 130 sucks indoor air from the interlayer duct 111 to the exhaust duct 113 and sends it out. The exhaust unit 130 may have exhaust fans 131. The exhaust fan 131 may be installed in a facility space provided for each floor to discharge air from the respective floor spaces to the exhaust duct 113. The rotation speed of the exhaust fan 131 may be adjusted by the inverter 132 for the exhaust fan. The exhaust fan inverter 132 may be connected to the sensor unit 160 and the system controller 170 and controlled through a network.

The exhaust fan 131 is controlled by the exhaust fan inverter 132 and the air supply fan inverter 122 so that the floor space is usually ventilated together with the air supply fan 121 to maintain a proper temperature. The system controller 170 controls the exhaust fan inverter 132 and the supply fan inverter 122 according to the air pollution and temperature information of the floor space provided from the sensor unit 160 to exhaust the exhaust fan 131 and the supply fan 121. By intelligently adjusting the air volume, the energy consumption can be reduced and the efficiency can be increased. In addition, in the event of a fire, the air supply fan 121 and the exhaust fan 131 may be independently controlled for each floor to prevent the spread of fire smoke, and to configure a flue gas path in a single direction for dust cleaning.

The cleaning dust collecting unit 140 cleans and collects the fire smoke passing through the air supply duct 112 and the exhaust duct 113. The cleaning dust collecting unit 140 may include water mist injectors 141 and collision baffles 142.

The water mist injectors 141 inject the water mist into the fire smoke passing through the air supply duct 112 and the exhaust duct 113. The sprayed water mist collects and separates the dust in the fire smoke by liquid crystal, liquid film, bubble or the like. At this time, it may be collected by the action of the collision of gas liquid, the destruction of bubbles, the inertia by the weight difference between the gas and particles, diffusion adhesion. Accordingly, the fire smoke may be purified and discharged from the air supply duct 112 and the exhaust duct 113 to the outside.

Some of the water mist injectors 141 are arranged along the passage of the air supply duct 112 to form the water mist injector 141 for the air supply duct, and the others are arranged along the passage of the exhaust duct 113 for the exhaust duct. The water mist injectors 141 are configured.

The water mist injectors 141 are controlled by the system controller 170. The water mist injector 141 may be supplied with water through a pipe branched independently from the fire fighting equipment. Valves may be installed in the piping. The valve may be controlled by the system controller 170 to open the piping in the event of a fire.

When a power failure occurs while the water mist injector 141 injects the water mist, the engine pump 101 may be driven to pump water in the water tank to the nozzle, thereby allowing the water mist to be continuously sprayed from the nozzle. Therefore, damage due to the interruption of operation of the water mist injector 141 can be prevented. The engine pump 101 is a pump using a power source of an engine such as an internal combustion engine. The engine pump 101 may be configured to automatically start / stop using the pressure difference in the pipe.

The collision baffles 142 are arranged to be offset from each other along the passages of the air supply duct 112 and the exhaust duct 113 to cause a fire smoke. The collision baffles 142 collide with the fire smoke rising along the passages of the air supply duct 112 and the exhaust duct 113, thereby enhancing the contact between the particles of the fire smoke and the particles of the water mist to activate the gas-liquid contact. . Therefore, the cleaning dust collection effect can be further improved.

Some of the collision baffles 142 are arranged to be offset from each other along the passage of the air supply duct 112 to constitute collision baffles 142 for the air supply duct, and others are arranged to be offset to each other along the passage of the exhaust duct 113 to exhaust. The impact baffles 142 for the ducts are constructed.

The collision baffles 142 for the air supply duct may be arranged in one row on both vertical inner walls of the air supply duct 112, and may be configured in two rows. The collision baffles 142 in one row are arranged vertically and spaced apart from the other vertical inner wall of the air supply duct 112 while being fixed to one vertical inner wall of the air supply duct 112. The collision baffles 142 of the other row are arranged up and down to be offset from the collision baffles 142 of one row and spaced apart from one vertical inner wall of the air supply duct 112 in a state fixed to the other vertical inner wall of the air supply duct 112. . The collision baffles 142 may all be arranged in an inclined form in the same direction.

The air supply duct water mist injector 141 may be disposed at each upper side of the collision baffle 142 in any one row. The exhaust duct collision baffles 142 are arranged in the exhaust duct 113 in the same manner as the air supply duct collision baffles 142, and the exhaust duct water mist injector 141 also has a It may be arranged per upper side. Of course, the arrangement of the collision baffles 142 and the water mist injector 141 is not limited to the illustrated, and may be variously configured.

Impingement baffle 142 may be made of a porous structure to further activate the gas-liquid contact. For example, the collision baffle 142 may have a plurality of through holes 142a, and the collision baffles 142b may be disposed on the upper sides of the through holes 142a at intervals. The fire smoke passes through the through hole 142a from the lower side of the through hole 142a and then hits the collision plate 142b to escape to the periphery of the collision plate 142b. In this process, gas-liquid contact can be further activated. The impingement plate 142b may be disposed so that a portion thereof is connected to the periphery of the through hole 142a and the remaining portion is spaced apart from an upper side of the through hole 142a.

The contaminated water treatment unit 150 processes contaminated water generated during the cleaning dust collection of the cleaning dust collecting unit 140. The contaminated water treatment unit 150 may include a sump 151 and a drain pump 152. The sump 151 and the drain pump 152 may be installed at the lowest floor of the underground composite commercial facility 10. Sump 151 collects contaminated water in the event of a fire. The drain pump 152 discharges and processes the contaminated water collected in the sump 151 after the fire is extinguished.

The level sensor 165 may measure the level of the sump 151 and provide it to the system controller 170. Based on the information provided from the water level sensor 165, the system controller 170 drives the drain pump 152 to collect the contaminated water in the event of a fire and drains the drain pump 152 after draining it from the sump 151. Stop it. In addition, the system controller 170 may prevent the flooding damage by draining by the drain pump 152 such that the water level of the sump 151 does not exceed the set level. At this time, when a power failure occurs, the engine pump 101 may be driven to drain the water level of the sump 151 so as not to exceed the set level.

The sensor unit 160 measures temperature and air pollution of each floor of the underground complex commercial facility 10 and detects a fire. The sensor unit 160 includes temperature sensors 161 for measuring the temperature of each floor, air pollution measuring sensors 162 for measuring the air pollution for each floor, and a fire detector 163.
