The oyster mushroom cultivation house typically has multiple layers of growing shelves that cause the disturbance of air circulation inside the mushroom house. Due to this instability in the internal environment, growth distinction occurs according to the area of the growing shelves. It is known that minimal air circulation around the mushroom cap facilitates the metabolism of mushrooms and improves their quality. For the purpose of this study, a CFD analysis FLUENT R16 has been carried out to improve the internal environment uniformity of the oyster mushroom cultivation house. It is found that installing a section of the working passage towards the ceiling is to maintain the internal environment uniformity of the oyster mushroom cultivation house. When all the environment control equipment – including a unit cooler, an inlet fan, an outlet fan, an air circulation fan, and a humidifier – were operated simultaneously, the reported Root Mean Square (RMS) valuation the growing shelves were as follows: velocity 23.86%, temperature 6.08%, and humidity 2.72%. However, when only a unit cooler and an air circulation fan operated, improved RMS values on the growing shelves were reported as follows: velocity 23.54%, temperature 0.51%, and humidity 0.41%. Therefore, in order to maintain the internal environment uniformity of the mushroom cultivation house, it is essential to reduce the overall operating time of the inlet fan, outlet fan, and humidifier, while simultaneously appropriately manage the internal environment by using a unit cooler and an air circulation fan.

시설재배 멜론은 소득이 비교적 높고 시설 내 환경 변화에 민감한 작목이다. 특히 여름 고온기재배 시에는 광합성 저하와 호흡 증가로 인해 멜론의 생산성과 품질이 저조하다. 고품질 멜론 생산을 위해서 는 시설 내 기온과 습도를 적정 조절하는 것이 매우 중요하다. 본 연구는 고온기 멜론재배 시에 포그 및 공기유동팬을 이용한 온도와 습도 조절이 과실 품질에 미치는 효과를 구명하고자 하였다. 그 결과, 포그와 유동팬을 가동 할 때 시설 내 기온은 최대 7℃, 평균 3.2℃ 강하되었고 상대습도는 최대 28%, 평균 12% 상승하였다. 이러한 온도와 습도 조건의 영향으로 무처리(천창과 측창환기 실시)에 비하여 멜 론의 과중이 300g, 당도가 1.5°Bx 각각 높았다.
