What are the factors that affect the insulation of glass greenhouses?

The heat source of the solar greenhouse comes from solar radiation during the day. When designing the glass greenhouse, it absorbs more heat energy during the day, loses less heat energy at night, stores more heat, and cools down slowly at night to ensure the normal growth of crops.

Generally, the solar radiant heat obtained in the greenhouse is dissipated outward in the following 5 ways:

①Through flow heat release on the covered surface of the greenhouse;

②The ground heat transfer of indoor soil;

③The heat released through gaps or vents;

④The heat transfer of latent heat of water evaporation, transpiration, condensation, etc.;

⑤The heat used by crop growth.
