摘要：本文通過理論公式推導計算、經(jīng)驗分析計算、熱仿真分析計算，得到了DKHR500風機在4500m海拔條件下所需要的風量，利用這些方法也可以得到不同型號風機在不同海拔條件下所需風量大小，為設計人員設計選型提供了思路。 關鍵詞：高海拔地區(qū);風機風量 Abstract: This DKHR500 type fan capacity is obtained at 4500m altitude through Theoretical formula derivation calculation, empirical analysis calculation, thermal simulation analysis calculation. The capacity of different types fan is also obtained by these approa[登陸后可查看全文]
