The Ir-Radiation Transmission Coefficient of a Water Condensate Film on Internal Solar Greenhouse Surfaces and Hotbed Transparent Covers as a Function of Thickness

摘要

The experimental results are presented on the determination of IR-radiation transmission coefficient of a water condensate film on internal surfaces of transparent solar greenhouse film covers and hotbeds partially permeable to IR radiation as a function of thickness. It is established that water condensate films 60 μm and thicker can be considered impermeable to IR radiation.
