1 , the main greenhouse heat radiation from the sun , according to the following table to select the general values ??of solar radiation and greenhouse ventilation rate required .
2 , greenhouse wet curtain of Installation :
Greenhouse area : 100m x 45m = 4500m2
Shade was 60% , outside solar radiation 900 W / m2
Ventilation volume = area x rated air volume of greenhouse
= 100 x 45 x 210 = 945000m3 / h
= 262m3 / h
Required ventilation ÷ area = wet curtain off curtain speed
= 262 ÷ 1.5 = 175m2
