Abstract

The present invention enables a bypass chamber to be formed in an independent space separated from a space, where a heat exchanging device is disposed on a side area not upper and lower sides of a housing. Therefore, the small ventilation device with a small size and low height since the device is mounted in the small space such as a ceiling can secure the bypass chamber performing various functions at the sufficient size. Moreover, while performing a bypass mode, the present invention can allow external air to be introduced to an indoor space without heat exchange with indoor air to perform a ventilation effect like opening a window.

Description

소형환기장치{Small ventilation device}Small ventilation device

본 발명은 소형환기장치에 관한 것이다.The present invention relates to a small ventilation device.

일반적으로 건물 내부에는 실내의 오염된 공기를 외부로 배출시키고, 외부의 신선한 공기를 실내로 공급할 수 있도록 환기장치가 설치된다.In general, a ventilation device is installed inside a building to discharge polluted air from the room to the outside and supply fresh air from the outside to the room.

환기장치는 환기용량에 따라 소형환기장치, 대형환기장치로 대별된다.Ventilation devices are broadly classified into small ventilation devices and large ventilation devices according to ventilation capacity.

최근 들어, 소형환기장치에 다양한 기능이 요구되고 있다.Recently, various functions are required for a small ventilation device.

예를 들어, 실내와 실외의 온도차가 적은 봄철이나 가을철에 실내공기와 실내공기가 열교환소자를 거치지 않고 실내 공기를 환기시키는 바이패스기능이 요구되고 있다.For example, a bypass function for ventilating indoor air without passing through a heat exchange element between indoor air and indoor air in spring or autumn when the temperature difference between indoor and outdoor is small is required.

또한, 미세먼지, 황사 등으로 대기오염이 심각한 환경에서, 공기정화기능이 요구되고 있다.In addition, in an environment where air pollution is severe due to fine dust and yellow dust, an air purification function is required.

또한, 코로나 바이러스등과 같은 전염병의 창궐로 인해, 공기살균기능이 요구되고 있다.In addition, due to the outbreak of infectious diseases such as corona virus, air sterilization function is required.

그러나, 소형환기장치는 천장 등 협소한 공간에 장착되는 관계로, 크기가 작고 높이가 낮아, 이 모든 기능을 담아 실행하기 어렵다.However, since the small ventilation device is mounted in a narrow space such as a ceiling, it is difficult to carry out all these functions due to its small size and low height.

또한, 종래 바이패스 모드를 기능을 가진 소형환기장치는, 바이패스모드 실행시 실외공기가 전혀 유입되지 못하고, 단순히 실내공기만 외부로 배출할 수 있다. 따라서, 창문을 연 것과 같은 환기 효과를 누리기 어렵다.In addition, in the conventional small ventilation device having a bypass mode function, when the bypass mode is executed, outdoor air cannot be introduced at all, and only indoor air can be discharged to the outside. Therefore, it is difficult to enjoy the same ventilation effect as opening a window.

Accordingly, it is possible to purify and sterilize the air by sterilizing the indoor air. In addition, the bypass chamber itself can be sterilized.

본 발명은 실외공기가 열교환소자로 유입되는 공간, 즉 제2실외측 급기실에 자외선 살균기를 구비한다. 따라서, 세균 등이 제거된 깨끗한 공기를 실내로 공급할 수 있다.According to the present invention, an ultraviolet sterilizer is provided in a space in which outdoor air flows into a heat exchange element, that is, in the second outdoor air supply chamber. Accordingly, clean air from which bacteria and the like are removed can be supplied to the room.

본 발명은 환기모드, 바이패스모드, 공기청정모드, 자동모드를 실행할 수 있어, 실내공기를 항상 쾌적하게 유지할 수 있다. 또한, 공기청정모드와 열교환소자의 결로를 제거할 수 있는 청소모드를 겸비한다. 즉, 공기청정모드 작동시 실내공기만을 열교환소자로 유동시킴으로써, 환기모드에서 실내공기와 실외공기의 온도차로 인해 열교환소자에서 발생할 수 있는 결로를 제거할 수 있다.The present invention can execute a ventilation mode, a bypass mode, an air cleaning mode, and an automatic mode, so that indoor air can always be maintained comfortably.

At this time, heat exchange between the indoor air and the outdoor air is performed.

실외공기의 유입을 위해서는, 실외측 흡입구용 댐퍼(D410)를 열고 급기용 송풍기(310)를 작동시켜, 실외측 흡입구(111)를 통해 실외공기를 흡입하여 제1실외측 급기실(R11), 제2실외측 급기실(R12), 열교환소자(200), 실내측 급기실(R2)을 거쳐 실내측 배출구(114)로 배출시킨다(도 4의 점선화살표 참고).In order to introduce outdoor air, open the damper (D410) for the outdoor suction port and operate the air supply blower (310) to suck the outdoor air through the outdoor suction port (111) to the first outdoor air supply chamber (R11), It is discharged to the indoor outlet 114 through the second outdoor air supply chamber R12, the heat exchange element 200, and the indoor air supply chamber R2 (refer to the dotted arrow in FIG. 4).

구체적으로, 실외측 흡입구용 댐퍼(D410)가 열리면, 실외측 흡입구용 덕트(410), 제2실외측 급기실(R12), 열교환소자(200), 실내측 급기실(R2), 실내측 배출구용 덕트(440)로 유로가 형성된다. 급기용 송풍기(310)가 작동되면, 실외공기가 실외측 흡입구용 덕트(410)로 흡입된다. 실외측 흡입구용 덕트(410)는 제1실외측 급기실(R11)을 관통하여 제2실외측 급기실(R12)로 연결되어 있으므로, 실외공기는 실외측 흡입구용 덕트(410)를 통해 제2실외측 급기실(R12)로 바로 유입된다. 유입된 실외공기는 제2실외측 급기실(R12)에 설치된 자외선 살균기(UV)에 의해 살균된다. 살균된 실외공기는 열교환소자(200)의 측면에 설치된 필터(F)를 통해 정화된 후 열교환소자(200)의 유로를 따라 실내측 급기실(R2)로 유입된다. 유입된 공기는 실내측 배출구용 덕트(440)를 통해 실내로 배출된다. Specifically, when the outdoor intake damper D410 is opened, the outdoor intake duct 410, the second outdoor air supply chamber R12, the heat exchange element 200, the indoor air supply chamber R2, and the indoor exhaust port A flow path is formed by the duct 440 for use. When the air supply blower 310 is operated, outdoor air is sucked into the outdoor suction duct 410 . Since the outdoor air inlet duct 410 passes through the first outdoor air supply chamber R11 and is connected to the second outdoor air supply chamber R12, the outdoor air flows through the second outdoor air intake duct 410 through the outdoor air inlet duct 410. It flows directly into the outdoor air supply chamber (R12). The introduced outdoor air is sterilized by an ultraviolet sterilizer (UV) installed in the second outdoor air supply chamber (R12). The sterilized outdoor air is purified through the filter F installed on the side of the heat exchange element 200 and then flows into the indoor air supply chamber R2 along the flow path of the heat exchange element 200 . The introduced air is discharged into the room through the duct 440 for the indoor outlet.

구체적으로, 실외측 배출구용 댐퍼(D420)와 제2실내측 개폐구용 댐퍼(D124)가 열리면, 실내측 흡입구용 덕트(430), 제1실내측 배기실(R31), 제2실내측 배기실(R32), 열교환소자(200), 실외측 배기실(R4), 실외측 배출구용 덕트(420)로 유로가 형성된다. 배기용 송풍기(320)가 작동되면, 실내공기가 실내측 흡입구용 덕트(430)로 흡입된다. 흡입된 실내공기는 제1실내측 배기실(R31)로 유입되고, 제2실내측 개폐구(124)를 통해 제2실내측 배기실(R32)로 유입된다. 제2실내측 배기실(R32)로 유입된 열교환소자(200)의 유로를 따라 실외측 배기실(R4)로 유입된 후 실외측 배출구용 덕트(420)를 통해 실외로 배출된다. Specifically, when the damper D420 for the outdoor outlet and the damper D124 for the second indoor opening/closing port are opened, the indoor intake duct 430, the first indoor exhaust chamber R31, and the second indoor exhaust chamber are opened. (R32), the heat exchange element 200, the outdoor exhaust chamber (R4), the outdoor side exhaust duct 420 is formed with a flow path. When the exhaust blower 320 is operated, indoor air is sucked into the indoor intake duct 430 . The sucked indoor air flows into the first indoor exhaust chamber R31 and flows into the second indoor exhaust chamber R32 through the second indoor opening/closing opening 124 . It flows into the outdoor exhaust chamber R4 along the flow path of the heat exchange element 200 introduced into the second indoor exhaust chamber R32, and then is discharged to the outside through the outdoor exhaust duct 420.

이를 통해, 살균 정화된 깨끗한 실외공기가 실내로 유입되고, 배출되는 실내공기와 유입되는 실외공기 간에 열교환이 이루어져 유입되는 실외공기의 실내공기와의 온도차를 줄일 수 있다.Through this, clean outdoor air that has been sterilized and purified is introduced into the room, and heat exchange is performed between the discharged indoor air and the incoming outdoor air, thereby reducing the temperature difference between the incoming outdoor air and the indoor air.

[바이패스모드(M2)][Bypass Mode (M2)]

바이패스모드(M2)가 선택되면, 도 5에 도시된 바와 같이, 실외공기가 실내로 유입되고, 실내공기가 실외로 배출되며, 이때 실내공기와 실외공기의 열교환은 이루어지지 않는다.When the bypass mode M2 is selected, as shown in FIG. 5 , outdoor air is introduced into the room and the indoor air is discharged to the outside.

In order to purify the indoor air, the first damper D123 for the indoor opening and closing and the damper D122 for the second outdoor opening and closing are opened, and the blower 310 for supplying air is operated to operate the indoor air through the indoor suction port 113. is sucked in and passes through the first indoor exhaust chamber (R31), the bypass chamber (R5), the second outdoor air supply chamber (R12), the heat exchange element 200, and the indoor air supply chamber (R2) through the indoor outlet 114 ) (refer to the solid arrow in FIG. 6).

구체적으로, 제1실내측 개폐구용 댐퍼(D123), 제2실외측 개폐구용 댐퍼(D122)가 열리면, 실내측 흡입구용 덕트(430), 제1실내측 배기실(R31), 바이패스실(R5), 제2실외측 급기실(R12), 열교환소자(200), 실내측 급기실(R2), 실내측 배출구용 덕트(440)로 유로가 형성된다. 급기용 송풍기(310)가 작동되면, 실내공기가 실내측 흡입구용 덕트(430)로 흡입된다. 흡입된 실내공기는 제1실내측 배기실(R31)로 유입되고, 제1실내측 개폐구(123)를 통해 바이패스실(R5)로 유입된다. 유입된 실내공기는 바이패스실(R5)에 설치된 자외선 살균기(UV)에 의해 살균된다. 살균된 실외공기는 바이패스실(R5)에 설치된 필터(F)를 통해 정화된 후 제2실외측 개폐구(122)를 통해 제2실외측 급기실(R12)로 유입된다. 제2실외측 급기실(R12)로 유입된 실내공기는 자외선 살균기(UV)에 의해 재살균된다. 재살균된 실내공기는 열교환소자(200)의 측면에 설치된 필터(F)를 통해 정화된 후 열교환소자(200)의 유로를 따라 실내측 급기실(R2)로 유입된다. 실내측 급기실(R2)로 유입된 실내공기는 실내측 배출구용 덕트(440)를 통해 실내로 배출된다. Specifically, when the damper for the first indoor opening/closing port D123 and the second damper D122 for the outdoor opening/closing port are opened, the indoor intake duct 430, the first indoor exhaust chamber R31, and the bypass chamber ( R5), the second outdoor air supply chamber (R12), the heat exchange element 200, the indoor air supply chamber (R2), the flow path is formed with a duct 440 for the indoor side outlet. When the air supply blower 310 is operated, the indoor air is sucked into the indoor air intake duct 430 . The sucked indoor air flows into the first indoor exhaust chamber R31 and flows into the bypass chamber R5 through the first indoor opening/closing opening 123 . The introduced indoor air is sterilized by an ultraviolet sterilizer (UV) installed in the bypass chamber (R5). The sterilized outdoor air is purified through the filter F installed in the bypass chamber R5 and then flows into the second outdoor air supply chamber R12 through the second outdoor opening/closing opening 122 . The indoor air introduced into the second outdoor air supply chamber R12 is re-sterilized by an ultraviolet sterilizer UV. The re-sterilized indoor air is purified through the filter F installed on the side of the heat exchange element 200 and then flows into the indoor air supply chamber R2 along the flow path of the heat exchange element 200 .

이를 통해, 살균 정화된 깨끗한 실내공기가 실내로 지속적으로 공급되어, 실내공기가 정화될 수 있다.Through this, clean indoor air that has been sterilized and purified is continuously supplied to the room, so that the indoor air can be purified.

한편, 환기모드(M1)에서는 열교환소자(200)에서 실내공기와 실외공기의 온도차로 인한 결로가 발생할 수 있다. 공기청정모드(M3)는 실내공기의 순환만 이루어지므로, 공기청정모드(M3)를 통해 열교환소자(200)의 결로를 제거할 수 있어, 공기청정모드(M3)는 청소모드로도 작동한다. On the other hand, in the ventilation mode M1, condensation may occur in the heat exchange element 200 due to a temperature difference between the indoor air and the outdoor air. Since the air cleaning mode M3 only circulates the indoor air, dew condensation on the heat exchange element 200 can be removed through the air cleaning mode M3, and the air cleaning mode M3 also operates as a cleaning mode.
