Thermal screen : used to maintain inner temperature of the greenhouse, when the sunlight is weak. Indeed, in wintertime or at night, after being deployed, it is used to keep heat and radiation. On the opposite, it is able to prevent the greenhouse from radiation and heat during hot periods of the year.
Ventilation capacity : maximum volume of air exchanged by a fan in m³/h or m³/m².h.
Ventilation – natural/forced : used to exhaust heat and moisture in order to refresh the air within the greenhouse. Therefore, it is the exchange of inner air and external air of the greenhouse. Natural ventilation depends on wind, temperature differences and vents dimensions, while forced ventilation refers to technical methods such as fans and vents opening characteristics.
Ventilation rate : volume of exchanged air in m³/m².h or m³/h.
Vents : ventilation windows located in the roof or the side walls of the greenhouse.
