본발명은 음압실 변환 공조시스템은 내부에 송풍기(10)와, 열교환기 또는 전기히터등 코일이 설치되어, 외부로부터 공급되는 냉매의 열원에 의해, 열교환기(102)를 통해 실내공기를 히팅 내지 냉각하거나 전기히터 등에 의해 히팅하는 공조기(100)의 급기닥트(110)를 통해 외부공기가 실내에 연결된다. 상기 열교환기는 실내의 공기는 배기닥트(120)를 통해 외부로 배기된다. 상기 배기닥트(120)를 통해 배기되는 공기중 일부는 리턴닥트(130)를 통해 공조기(120)에 리턴되며, 배기닥트(120)에는 배기팬(121)이 설치된다.In the present invention, the negative pressure room conversion air conditioning system has a blower 10 and a coil such as a heat exchanger or an electric heater installed therein, and heats indoor air through the heat exchanger 102 by a heat source of refrigerant supplied from the outside. External air is connected to the room through the air supply duct 110 of the air conditioner 100 that is cooled or heated by an electric heater or the like. In the heat exchanger, indoor air is exhausted to the outside through the exhaust duct 120. Some of the air exhausted through the exhaust duct 120 is returned to the air conditioner 120 through the return duct 130, and an exhaust fan 121 is installed in the exhaust duct 120.

그리고 상기 리턴닥트(130)의 배기닥트(120)에서의 리턴닥트 분기점(131)은 배기팬(121) 이후에 설치되며, 상기 배기닥트(120)의 전방부에는 음압발생용 닥트(140) 라인이 연결되는 음압발생 분기부(144)가 형성된다.And the return duct branch point 131 in the exhaust duct 120 of the return duct 130 is installed after the exhaust fan 121, and the front part of the exhaust duct 120 has a duct 140 line for generating negative pressure A negative pressure generating branch 144 connected thereto is formed.

상기 음압발생용 닥트(140)에는 음압발생용 송풍기(141)가 설치되어 공기를 흡입하여 실내를 음압으로 만든다.A blower 141 for generating negative pressure is installed in the negative pressure generating duct 140 to suck air to make the room negative pressure.

음압발생 분기부(144) 이후의 배기닥트(120)에는 배기닥트 자동댐퍼(142)가 설치되어 평상시는 개방되었다가 비상시 음압실로 실내를 사용시 폐쇄된다. 그리고An exhaust duct automatic damper 142 is installed in the exhaust duct 120 after the negative pressure generating branch 144, and is normally open, but is closed when the room is used as a negative pressure chamber in an emergency. and

상기 음압발생용 송풍기(141) 전방에는 자동댐퍼(142)가 설치되어 평상시에는 폐쇄되었다가 비상시 실내를 음압실로 사용시 개방한다.An automatic damper 142 is installed in front of the blower 141 for generating negative pressure, which is normally closed and opened when the room is used as a negative pressure chamber in an emergency.

음압발생용 송풍기(141)와 자동댐퍼(142) 사이에는 필터(143)가 설치되며, 상기 음압발생용 닥트에는 내부에 자외선램프가 설치되어 공기를 살균할 수 있다. 상기 음압발생용 닥트(140)는 항균철판으로 제작되어 세균을 살상할 수 있다.A filter 143 is installed between the negative pressure generating blower 141 and the automatic damper 142, and an ultraviolet lamp is installed inside the negative pressure generating duct to sterilize the air. The duct 140 for generating negative pressure is made of an antibacterial iron plate and can kill bacteria.

그리고 실내에는 압력센서가 설치되어, 진공도가 설정치에 도달하면, 제어기의 제어부는 음압발생 송풍기의 구동을 멈춘다.In addition, a pressure sensor is installed in the room, and when the vacuum level reaches the set value, the control unit of the controller stops driving the negative pressure generating blower.

본발명은 제어부는 실내에 설정된 음압이 유지되는 상태에서는 송풍기는 음압발생 송풍기가 작동되지 않으면 작동되지 않게 제어하여 음압이 설정치에서 벗어나 상압으로 복원되지 않게 한다. 특히 가동중에도 송풍기의 풍량은 음압발생 송풍기의 풍량보다 크지 않게 송풍기의 팬속도를 제어한다. 출입문이 열려 음압이 순간적으로 깨어지는 경우에는 제어부는 비상상태로 송풍기를 정지시키고 설정된 음압이될때까지 음압발생 송풍기만 작동하게 한다.In the present invention, the control unit controls the blower not to operate when the negative pressure generating blower is not operated in a state where the negative pressure set in the room is maintained, so that the negative pressure does not deviate from the set value and is restored to normal pressure. In particular, even during operation, the fan speed of the blower is controlled so that the air volume of the blower is not greater than the air volume of the negative pressure generating blower. When the door is opened and the negative pressure is momentarily broken, the control unit stops the blower in an emergency state and operates only the negative pressure generating blower until the set negative pressure is reached.

따라서 본발명은 실내에 음압발생용 송풍기 및 닥트가 설치되어 코로나 바이러스 발생 등의 비상시 실내를 음압실로 사용하여 병균으로부터의 오염을 방지하는 현저한 효과가 있다.Therefore, the present invention has a remarkable effect of preventing contamination from germs by using the room as a negative pressure room in the event of an emergency such as corona virus by installing a blower and a duct for generating negative pressure in the room.
