With the development of production, the application of greenhouses has become more extensive, and the multi-span greenhouses have become more and more popular. The multi-span greenhouse is an upgrade of the greenhouse. It connects the original independent single-room greenhouse with scientific methods, reasonable design and excellent materials. In fact, it is a kind of super large greenhouse, or understood as a kind of expansion.
Greenhouse cooling methods can be divided into the following categories according to the physical conditions used:
1. Evaporative cooling method: Use indoor spray, water spray or install evaporator (wet wall, wet curtain) to "eliminate" solar radiation heat energy through water evaporation.
2. Shading method: Install shading coverings on the roof at certain intervals, which can reduce the net solar radiation by about 50%, and the average indoor temperature is reduced by about 2℃.
3. Ventilation method: Use ventilation fans and other artificial methods for forced ventilation to reduce the air temperature in the greenhouse.
