When the outdoor temperature increases to be unsuitable for crop growth, close the skylights and side windows, start the fan to forcibly extract the indoor air to create a negative pressure, and at the same time start the water pump of the wet curtain system to pour water on the wet curtain, and the outdoor air is negatively pressured When it is sucked into the room, it passes through the gap of the wet curtain at a certain speed, which causes the water to evaporate. Therefore, it will send moist and cold air to the room temperature, and the temperature of the greenhouse will drop. The wet curtain has a thickness of 100 mm, a height of 1.5 to 2 meters, and an aluminum alloy frame. The wet curtain is composed of water pipes and water.
To cool the greenhouse, you need to understand the principle of greenhouse cooling, and use the cooling principle to set up cooling equipment to achieve the purpose of greenhouse temperature adjustment.
The greenhouse can be cooled by ventilation measures. The most basic cooling method of ventilation and cooling is used when the temperature requirements are not strict. If the outside temperature is too high, the indoor temperature can not be reduced by only using ventilation and cooling. This is needed at this time Professional cooling fan equipment is now available.
The commonly used cooling methods for greenhouses include: opening doors (windows) for ventilation and cooling, forced cooling of mechanical equipment, heat exchange cooling, and water curtain and wet curtain fan cooling.
