摘要：本文通過理論公式推導(dǎo)計(jì)算、經(jīng)驗(yàn)分析計(jì)算、熱仿真分析計(jì)算，得到了DKHR500風(fēng)機(jī)在4500m海拔條件下所需要的風(fēng)量，利用這些方法也可以得到不同型號風(fēng)機(jī)在不同海拔條件下所需風(fēng)量大小，為設(shè)計(jì)人員設(shè)計(jì)選型提供了思路。 關(guān)鍵詞：高海拔地區(qū);風(fēng)機(jī)風(fēng)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]
