Surface water circulation system
Using underground cold water according to the fluidity of the surface cooler circulation system and adding a centrifugal fan can achieve the actual effect of cooling at night without increasing the relative humidity of the air in the greenhouse. It can also use surface water resources and increase the temperature of the generator set, which can not only reduce the temperature, increase the temperature, but also save energy and environmental protection, but the cost is too high at this stage.
Cooling by cooling water curtain
The cooling water curtain cooling is the whole process of the external high temperature gas passing over the soaking cooling water curtain, humidifying and cooling, and generating cold air, which is digested and absorbed by the controllable house to recover the waste heat, and then discharged to the outdoors. It mainly uses the volatilization of water to cool down. Since the volatilization of water must be digested and absorbed, a part of the heat generated by the arch can be taken away. In addition, a cooling fan is activated to extract the hot cyclone in the greenhouse to cool down.
Air circulation
There are three key benefits in choosing the method based on the basis of course: one is to remove the waste heat recovery of the arch shed and reduce the temperature; the other is to remove unnecessary water from the arch shed and reduce the environmental humidity; the third is to adjust the composition content of the air in the room and increase the air content. The content of carbon dioxide to enhance the photosynthesis of plants. In addition, we should pay attention to increasing the total area of natural ventilation, the continuous butterfly window ventilation that can be applied at the top of the greenhouse, and increase the total area of natural ventilation around the side windows. That way, in the autumn and spring when it is not too hot, the air in the side windows and top windows can of course ventilate the flow of goods to cool down.
