Cooling principle wet curtain wall; wet curtain wall common to negative pressure ventilation cooling mode. Negative pressure ventilation and cooling mode, the suction fan for the room dirty, wet curtain of hot air pumped, and installed in the opposite suction fan wet curtain wall is used for air intake. Fresh outdoor hot air passes through the wet curtain wall was wet hole, with water filtration and heat exchange cooling. The source of the name; because it is typically installed on factories, cafes, greenhouse walls, similar to the wall, so called wet curtain wall outside the solar radiation intensity: After 900W / M2 calculate the amount of ventilation required in determining wet curtain area to consider strike the right balance between wet curtain of efficiency, resistance and economy. The more wet curtain installation, of course, the better the cooling effect of the wet curtain manufacturers, ventilation resistance is also smaller wet curtain cleaning, but the higher the investment; and vice versa. Therefore, we recommend selection based on experience following the curtain wind speed: 100 mm Wet curtain: 1.2-1.5 m / s. The choice of the thickness of wet screens, wet screens in addition to considering the role of geographical location, climatic conditions, we must also look at greenhouse wet curtain and fan of distance and flower crop sensitivity to temperature. If the distance between the fan and the greater the wet curtain (usually more than 32 meters above), it is recommended to use 15 cm thick wet curtain; and if the floriculture greenhouse temperature sensitive, high temperature tolerance of difference, it is recommended to use 15 cm thick wet curtain. Conversely, if the distance between the greenhouse wet curtain and fan less sensitive to temperature from the flower or the low level, you can use 10 cm thick, wet curtain.
