Thermal Shading Screen
Shading screens are meant to reduce the radiation inside the greenhouse when the damage of the increasing temperature is greater than the damage of reducing the radiation. Different screens create different levels of shading. The screens can be operated by motors which can be controlled by the control system. This enables automatic operation of the screens, regulated by sensors of temperature and radiation.
Thermal screens are shade screens of which their bottom side is covered by materials that reflect radiation. Spreading the thermal screens after sunset keeps the heat (infra-red radiation) that is emitted from the plants and the soil, inside the greenhouse, which elevates the temperature in the plants environment during the night.
