본 발명은 양축모터 듀얼팬을 적용한 에너지절감형 스탠드 공기순환기에 관한 것이다.The present invention relates to an energy-saving stand air circulator to which a dual-axis motor dual fan is applied.

일반적으로 건물의 실내가 외부와 통풍이 잘되지 않은 상태에서 실내에서 사람이 장시간 활동하게 되면 실내 공기의 오염 및 CO2 증가로 인하여 쾌적한 상태를 유지하지 못하게 되므로 실내를 환기시켜주어야 한다. 창문을 열어 환기시키게 되면 오염물질이 유입될 뿐만 아니라 내부 열 손실이 발생된다. 이러한 문제점을 해결하는 장치가 바로 전열교환소자가 구비된 환기시스템(일명, 공기순환기라고도 함)이다.In general, when a person is active indoors for a long time in a state where the interior of a building is not well ventilated with the outside, it is difficult to maintain a comfortable state due to contamination of the indoor air and an increase in CO2, so the room must be ventilated. Ventilation by opening windows not only introduces pollutants but also causes internal heat loss. A device that solves this problem is a ventilation system (aka, also referred to as an air circulator) equipped with a total heat exchange element.

대한민국 공개특허 제10-2019-0122074호(2019. 10. 29. 공개일)(이하, 선행기술이라 함)에는 환기시스템의 일예로, 건물의 벽에 설치되는 전열교환기와, 그 전열교환기와 건물의 실내(들)를 연결시켜 전열교환기를 거친 외부 공기를 실내로 유입되도록 안내하는 실외공기 유입배관과, 전열교환기와 건물의 실내(들)를 연결시켜 실내의 공기를 전열교환기를 거쳐 실외로 배출되도록 안내하는 실내공기 배출배관이 개시되어 있다.Republic of Korea Patent Publication No. 10-2019-0122074 (2019. 10. 29.

그러나 선행기술은 전열교환기를 건물의 벽에 실외와 연통되도록 설치되고 그 전열교환기에 실외공기 유입배관과 실내공기 배출배관을 설치하여 실내와 연결시키게 되므로 배관 구성이 복잡하여 설치가 어려울 뿐만 아니라 기존 건물에 설치하게 될 경우 설치가 더 어려운 문제점이 있다.However, in the prior art, the total heat exchanger is installed on the wall of the building to communicate with the outdoors, and the outdoor air inlet pipe and the indoor air discharge pipe are installed in the total heat exchanger to connect it to the room.
