The present invention relates to a ventilation device for mushroom cultivation, provided in the mushroom cultivation room temperature and humidity sensor for sensing temperature and humidity； A concentration measurement sensor provided in the mushroom cultivation room to measure carbon dioxide concentration； One end is located outside the mushroom cultivation chamber, the other end is disposed inside the mushroom cultivation chamber, and the outside air flowing into the mushroom cultivation chamber is connected to the outside air inlet pipe and the outside air inlet pipe located inside, and the inside of the mushroom cultivation chamber is introduced. Mixing chamber to form the first air by mixing the bet introduced from, Heat exchanger connected to the mixing chamber to exchange the temperature and humidity of the first air with predetermined conditions to form the second air, and the first air to heat exchanger A humidity control device having a blower that generates suction power to be transported along and blows out the second air and discharges the second air flowing out from the blower to the outside and inside of the mushroom cultivation chamber； An LED device that provides LED light to each layer of the mushroom badge holder formed in multiple stages in the mushroom growing room； And a control unit for controlling the mushroom cultivation chamber and the amount of the second air discharged to the outside based on the temperature and humidity sensed through the temperature and humidity sensor and the concentration measurement sensor.본 발명은 버섯 재배용 환기 장치에 관한 것으로서, 버섯재배실에 구비되어 온도 및 습도를 센싱하는 온습도 센서； 버섯재배실에 구비되어 이산화탄소 농도를 측정하는 농도측정센서； 일단이 버섯재배실의 외측에 위치하고, 타단이 버섯재배실의 내측에 배치되어 외기를 버섯재배실로 유입시키는 외기유입관, 내측에 위치하는 외기유입관에 연결되어 유입되는 외기와 버섯재배실의 내측에서 유입된 내기를 혼합하여 제1 공기를 형성하는 혼합챔버, 혼합챔버에 연결되어 제1 공기의 온도 및 습도를 기설정된 조건으로 교환하여 제2 공기를 형성하는 열교환기, 제1 공기가 열교환기를 따라 이송되도록 흡입력을 발생시키며, 제2 공기의 토출력을 발생시키는 송풍기 및 송풍기로부터 유출되는 제2 공기를 버섯재배실의 외측 및 내측으로 이동시키는 유출부를 구비하는 항습장치； 버섯재배실에 다단으로 형성된 버섯배지 거
