Customized Hot DIP Galvanized Steel Warm Poultry Farm Multi Span Garden House Greenhouse

Ventilation System

Multi-span membrane greenhouse is equipped with top ventilation and side ventilation of two kinds of natural ventilation.

The high temperature air in the greenhouse is collected in the top of the greenhouse, through the top window, high temperature air can be discharged outdoors, low temperature air will enter the greenhouse through side ventilation.

 

Its advantages are:

1, adjust the temperature in the greenhouse.

2, add carbon dioxide in the greenhouse.

3, reduce humidity, reduce the transmission of fungal diseases.

4, reduce indoor harmful gas content.

Cooling system
Cooling pad/fan cooling system uses water evaporation cooling principle to achieve the purpose of cooling, the core of the cooling system is to make water evaporation of the wet curtain special wet curtain can ensure that water evenly wet the whole cooling wet curtain wall.
When the air penetrates the wet curtain medium, the sensible heat of water and air exchange with the surface of the wet curtain medium is converted into latent heat of vaporization, so as to realize the humidification and cooling of the air.

The wet curtain is generally installed on the north side of the greenhouse, and the fan is generally installed on the south side of the greenhouse. When the need to cool down, start the fan, the greenhouse air forced out, resulting in negative pressure; At the same time, water pumps hit the wet curtain wall opposite.
When the outdoor air is sucked into the room by negative pressure, it passes through the gap of the water curtain at a certain speed, resulting in water evaporation and cooling. The cold air flows through the greenhouse, absorbs the indoor heat, and is discharged by the fan, so as to achieve the purpose of cooling.
