Water curtain wall, also known as wet curtain wall, is often used for negative pressure ventilation and cooling.
In the negative pressure ventilation cooling mode, the negative pressure fan is used to take away the dirty hot air in the room, and the water curtain wall installed opposite the negative pressure fan is used for air intake. When the outdoor fresh hot air passes through the wet holes on the water curtain wall, it is filtered and cooled by heat exchange with water.
The water curtain wall consists of two parts: the water curtain piece and the frame. According to the thickness of the water curtain, it can be divided into 10cm and 15cm. According to the frame material, it can be divided into three types: aluminum alloy, stainless steel iron and stainless steel. The water curtain wall with the thickness of 15cm has a better cooling effect, because when the outside hot air penetrates the water curtain, the path it passes is longer. Stainless iron water curtain wall is low in price and poor in quality, mainly because stainless iron is easy to rust and often wears out in a year or so, which will inevitably lead to water leakage of the water curtain wall.
