열회수 환기 시스템 및 이의 제어방법{System using heat recovery ventilator and method for controlling the same}Heat recovery ventilation system and its control method {System using heat recovery ventilator and method for controlling the same}

본 발명은 열회수 환기 시스템에 관한 것으로서, 보다 상세하게는 열회수 환기장치를 이용하여 건물의 실내공기를 효과적으로 환기할 수 있는 열회수 환기 시스템에 관한 것이다.The present invention relates to a heat recovery ventilation system, and more particularly, to a heat recovery ventilation system capable of effectively ventilating indoor air in a building using a heat recovery ventilation device.

일반적으로 공동주택, 사무실 또는 백화점, 대형마트 등 건물의 오염된 실내 공기를 외부로 배출시키고 외부의 새로운 공기를 실내공간으로 공급할 수 있도록 하기위해 전열교환기를 이용한 열회수 환기장치가 사용되고 있다.In general, a heat recovery ventilator using a total heat exchanger is used to discharge polluted indoor air of buildings such as apartment houses, offices, department stores, and large marts to the outside and supply new outside air to the indoor space.

즉, 통상의 전열교환기는 실내의 공기를 환기시킴에 있어, 갑작스런 냉기 및 열기가 외부에서 내부로 유입되지 않도록 실외공기를 실외로 배출되는 실내공기와 먼저 열교환 시켜주는 장치이다. 따라서, 전열교환기는 실내에서 발생한 휘발성 유기화합물질을 배기를 통하여 배출하고, 필터링한 외부의 신선한 공기를 실내로 흡입하는 방법으로 실내의 공기를 쾌적하게 유지한다.That is, a conventional total heat exchanger is a device that first exchanges heat with indoor air discharged to the outside to prevent sudden cool air and heat from entering the inside from the outside when ventilating indoor air. Therefore, the total heat exchanger discharges volatile organic compounds generated in the room through the exhaust and inhales the filtered external fresh air into the room to keep the indoor air comfortable.

이에, 일반적인 전열교환기의 작동을 설명하면, 공조된 실내의 공기를 외부로 배출할 때는 전열교환기 내에 설치된 배기팬이 작동하고, 이때의 정압으로 전열 교환기 소자를 통과하면서 실내에서 실외로 오염된 공기가 외부로 배출된다.Therefore, when explaining the operation of a general total heat exchanger, when the air in the conditioned room is discharged to the outside, the exhaust fan installed in the total heat exchanger operates, and the polluted air passes through the total heat exchanger element at a constant pressure at this time. discharged to the outside

종래의 열회수 환기장치는, 사용자의 조작에 의해서 단순 온/오프 작동되거나, 일정한 시간 간격으로 작동된다. 즉, 실내 공기의 질에 상관없이 작동되므로, 과도하게 작동되어, 외기가 과도하게 실내로 유입되어 에너지 손실이 크게된다.A conventional heat recovery ventilator is simply turned on/off by a user's manipulation or operated at regular time intervals. That is, since it operates regardless of the quality of indoor air, it operates excessively, and excessive outdoor air flows into the room, resulting in a large energy loss.

이러한 문제점을 해소하기 위해서, 실내의 특정위치에 실내의 공기질을 측정할 수 있는 공기 오염센서를 구비한 후, 측정된 오염도에 따라서, 열회수 환기장치를 작동할 수 있다. 그러나 신뢰성 있게 작동하는 공기 오염센서의 경우 고가이어서, 각 방마다 사용하는 경우 설치비가 과도하게 소요된다는 단점이 있다.In order to solve this problem, after installing an air pollution sensor capable of measuring indoor air quality at a specific location in the room, the heat recovery ventilator may be operated according to the measured pollution level. However, since air pollution sensors that operate reliably are expensive, there is a disadvantage in that installation costs are excessive when used in each room.

And to provide a control method thereof.

개선여부판단단계(S135)는, 복수의 공기질이 나쁜 실내공간(10)들로 부터 유입되는 공기질의 평균값을 기준값과 비교하여 판단한다.In the improvement determination step S135, an average value of air quality introduced from a plurality of indoor spaces 10 having poor air quality is compared with a reference value to determine whether or not the air quality is improved.

순차개방단계(S110) 이전에 분배기 및 관내에 잔존하는 공기를 배출하기 위해서, 배출팬(118)과, 공급팬(117)을 약하게 일정시간동안 작동하는 잔존공기 배출단계(S105)를 더 포함한다.In order to discharge the air remaining in the distributor and the tube before the sequential opening step (S110), the discharge fan 118 and the supply fan 117 are operated weakly for a certain period of time to further include a residual air discharge step (S105). .

개별 환기모드(S200)는, 환기가 필요한 개별 실내 공간(10)을 선택하는 단계(S210)와, 선택된 개별 실내 공간(10)과 연통되는 급기 댐퍼(220)와 흡기 댐퍼(320)를 개방한 후, 열회수 환기장치(100)를 동작하여, 환기하는 단계(S220)를 포함한다.In the individual ventilation mode (S200), the step of selecting an individual indoor space 10 requiring ventilation (S210) and opening the air supply damper 220 and the intake damper 320 communicating with the selected individual indoor space 10 Then, operating the heat recovery ventilator 100 to ventilate (S220).

상기와 같이, 본 발명의 실시예는 하나의 실내오염센서(130)를 사용함에도, 복수의 실내 공간 각각의 공기질을 개별적으로 관리할 수 있다는 장점이 있다.As described above, the embodiment of the present invention has the advantage of being able to individually manage the air quality of each of a plurality of indoor spaces even though one indoor pollution sensor 130 is used.

또한, 별도로 산소공급기를 열회수 장치에 구비함으로써, 별도로 산소를 공급하는 라인을 설치할 필요가 없을 뿐만 아니라, 산소의 농도도 효율적으로 측정하여 산소를 공급하므로, 산소를 필요한 곳에 원활하게 공급할 수 있다.In addition, since a separate oxygen supplier is provided in the heat recovery device, there is no need to separately install a line for supplying oxygen, and since oxygen is supplied by efficiently measuring the concentration of oxygen, oxygen can be smoothly supplied to a required place.

이상에서는 본 발명의 바람직한 실시예를 예시적으로 설명하였으나, 본 발명의 범위는 이와 같은 특정 실시예에만 한정되는 것은 아니며, 특허청구범위에 기재된 범주 내에서 적절하게 변경 가능한 것이다.In the above, preferred embodiments of the present invention have been described by way of example, but the scope of the present invention is not limited only to these specific embodiments, and can be appropriately changed within the scope described in the claims.
