Energy Conservation in Greenhouses

The heat loss in greenhouses is mainly achieved through the following channels: conduction and heat dissipation through glass enclosures, which can account for 70% to 80% of the total heat loss; Radiate and dissipate heat into the sky; Ventilation and heat dissipation; Air infiltration heat dissipation; Heat transfer in the ground. Greenhouse energy-saving is to reduce the heat dissipation of the greenhouse, and the effective method is to install insulation curtains, which can reduce the heat loss at night. On the premise of meeting crop lighting requirements, it is best to install double-layer transparent materials, which can reduce heat loss by 50%. It is also very effective to use cold resistant ditches and fill them with insulation materials to reduce heat transfer in the ground.
