Description

정풍량 환기장치{Ventilation apparatus with constant air volume}Ventilation apparatus with constant air volume

본 발명은 환기장치에 관한 것으로, 실내로 유입되는 외기와 실내로부터 배출되는 배기 간에 열교환을 발생시켜 폐열을 회수하는 한편, 실내로 유입되는 외기 및 배출되는 배기의 풍속을 측정한 후 팬의 모터 구동 속도를 조절함으로써 정풍량을 유지할 수 있도록 한, 정풍량 환기장치에 관한 것이다.
The present invention relates to a ventilator, and recovers waste heat by generating a heat exchange between the outside air introduced into the room and the exhaust discharged from the room, while driving the motor of the fan after measuring the wind speed of the outside air introduced into the room and the exhaust exhaust The present invention relates to a constant air amount ventilator, which is capable of maintaining a constant air amount by adjusting a speed.

일반적으로 공동주택, 주택의 발코니 또는 기계실에 설치되어 있는 폐열회수환기장치는 배기팬을 이용하여 실내의 오염된 공기를 열교환기를 통과시킨 후 외부로 배출하고, 급기팬을 이용하여 실외의 신선한 공기를 열교환기를 통과시킨 후 실내로 공급한다.In general, the waste heat recovery ventilator installed in a multi-family house, a balcony of a house or a machine room uses an exhaust fan to exhaust polluted air indoors through a heat exchanger and then discharges it to the outside. After passing through the heat exchanger, it is fed into the room.

이와 같은 기계식 환기과정에서 폐열회수 환기장치의 열교환기에서는 실내공기와 실외공기 사이의 열교환이 이루어진다.In the mechanical ventilation process, the heat exchanger of the waste heat recovery ventilator performs heat exchange between the indoor air and the outdoor air.

기계실 또는 발코니에 설치된 폐열회수 환기장치는 주택 내 각 방에 연통하는 급배기 덕트라인을 구비하고 있어, 안방, 거실 또는 서재 등 각 방의 환기가 개별적으로 이루어질 수 있는 구조로 되어 있다.The waste heat recovery ventilator installed in the machine room or balcony is provided with a supply / exhaust duct line communicating with each room in the house, so that each room such as a room, living room, or study room can be individually ventilated.

이와 같은 급배기 덕트라인을 구비한 폐열회수 환기장치의 경우 외풍의 영향과 급배기 덕트라인의 조건에 따라 압력손실 차이가 불가피하게 발생하게 되고, 이로 인하여 급기와 배기 풍량이 균형을 이루지 못해서 풍량차가 발생하게 되며, 이러한 급배기 풍량차에 의해 열교환기에서 급기와 배기 사이의 열교환 성능도 저하되는 문제점이 있다.In the case of the waste heat recovery ventilator provided with the air supply and exhaust duct line, the pressure loss difference is inevitably generated according to the influence of the outside air and the conditions of the air supply and exhaust duct line, resulting in an unbalance between the air supply and the exhaust air flow. The heat exchange performance between the air supply and the exhaust in the heat exchanger is also deteriorated by the air supply and exhaust air flow difference.

현재 이러한 폐열회수 환기장치는 초고층 고기밀화 되는 신축건물에 있어서 환기 문제가 이슈화되면서 냉난방 열부하를 경감시킴과 동시에 건강한 실내공기의 질을 확보할 수 있는 제품으로 선택되어 설치되고 있다.At present, the waste heat recovery ventilator is selected and installed as a product that can reduce the heating and cooling heat load while ensuring the quality of healthy indoor air as the ventilation problem is raised in the new high-density high-density building.

이러한 폐열회수 환기장치는 특성상 송풍기와 같은 기계장치와 덕트와 같은 부속물이 함께 시공됨에도 불구하고, 송풍기와 같은 기계장치만을 기준으로 풍량 및 열교환 성능을 표시하였으며, 이로 인해 실제 급배기 풍량비와 열교환 성능이 제품 성능과 일치하지 않는 문제점이 있었으며, 이러한 문제점을 해결하기 위해 현장에서 덕트 시스템상의 포함한 실제 풍량과 열교환 성능을 시험하는 것도 현실적으로 어려운 일이다.Although the waste heat recovery ventilator has the characteristics such as a blower and an attachment such as a duct, it shows the air flow rate and heat exchange performance based only on the mechanical device such as the blower, and as a result, the actual exhaust / air flow rate ratio and heat exchange performance There was a problem that was inconsistent with the product's performance, and in order to solve this problem, it was also practically difficult to test the actual air flow and heat exchange performance included in the duct system in the field.

이러한 문제점을 해결하기 위하여, 덕트 시스템 내부 및 건물 외부에 있어서의 풍량과 풍압 등의 환경적 요인에 기인한 압력손실의 변동에 상관없이 정풍량 성능을 유지하여 일정한 급배기 풍량과 열교환 성능을 실현할 수 있는 환기장치의 개발이 요구되고 있다.
In order to solve this problem, it is possible to realize constant air flow rate and heat exchange performance by maintaining the constant air flow performance regardless of fluctuations in pressure loss caused by environmental factors such as air flow and wind pressure inside and outside the duct system. There is a need for the development of ventilation systems.

예를 들어 입력장치를 통해 강풍, 중풍, 약풍 등으로 풍속을 조절하도록 구성할 경우 외기흡입구(14), 외기공급구(13), 실내공기흡입구(12), 실내공기배출구(11)의 직경이 150 mm인 경우 운전 모드별 풍량 및 풍속은 아래의 표 1과 같이 설정하여 운영될 수 있다.
For example, when the wind speed is controlled by an input device such as a strong wind, a middle wind, or a weak wind, the diameters of the outside air intake port 14, the outside air supply port 13, the indoor air intake port 12, and the indoor air outlet 11 are In the case of 150 mm, the air volume and wind speed for each operation mode may be set and operated as shown in Table 1 below.

운전모드Operation mode 풍량(㎥/hr)Air volume (㎥ / hr) 풍속(m/s)Wind speed (m / s) 강풍gale 275275 4.34.3 중풍A stroke 250250 3.93.9 약풍Breeze 200200 3.13.1

이 경우 입력장치를 통해 풍량을 강으로 설정하여 운전할 때, 풍속이 4.3 m/s보다 낮을 경우 컨트롤장치(60)는 모터의 회전수를 높이며, 풍속이 설정값보다 높을 경우 컨트롤장치(60)는 모터의 회전수를 내리게 된다.In this case, when the wind speed is set to strong through the input device, when the wind speed is lower than 4.3 m / s, the control device 60 increases the rotational speed of the motor, if the wind speed is higher than the set value, the control device 60 The speed of the motor is lowered.

중풍량 및 약풍량일 경우에도 위와 같은 방식으로 운영된다.Medium air volume and weak air volume are operated in the same manner as above.

이처럼 사용자가 원하는 모드로 풍속측정장치(50)를 통해 측정된 값에 따라 컨트롤장치(60)가 모터의 회전수를 조절하여 항상 정풍량을 갖게 되는 것이다.
As such, the control device 60 adjusts the number of revolutions of the motor in accordance with the value measured by the wind speed measuring device 50 in a mode desired by the user so as to have a constant wind amount.

조사한 결과 정압이 25 pa에서 250pa 범위에서 운영모드를 풍량 250 ㎥/hr 및 400 ㎥/hr로 운영한 결과 풍량이 10% 이내의 오참 범위로 유지되어 정풍량 기준을 만족하였다.As a result, the operation mode was operated with the air flow rate of 250 ㎥ / hr and 400 ㎥ / hr in the constant pressure range of 25 pa to 250 pa.

또, 이때의 소비전력은 정풍량 250㎥/hr 설정시 정압이 0에서 300 pa에 이를 동안 소비전력이 90 ~ 108W로 매우 낮게 나타났다.In addition, the power consumption at this time was very low as 90 ~ 108W while the static pressure reaches 0 to 300 pa when the constant air flow rate 250㎥ / hr.

즉, 본 발명에 따른 정풍량 환기장치는 외부로부터 흡입되는 풍속에 따라 회전수를 조절함으로써 일정한 정풍량을 유지하여 열교환이 안정적으로 이루어지면서 환기가 이루어지게 되는 것이다.
That is, the constant air volume ventilator according to the present invention is to maintain a constant constant air flow rate by adjusting the rotation speed in accordance with the wind speed is sucked from the outside while the heat exchange is made stable.
