The article presents the results of studies of the optical characteristics of a
composite polyethylene film (CPP) (South Korea), manufactured using the Heungil technology for
solar greenhouses with a single- and two-layer translucent coating. It has been established that in
the visible region of the spectrum the transmittance (T) of a two-layer translucent coating is lower
than that of a single-layer coating. In the infrared spectrum, the graphs of the transmittance of
one- and two-layer coatings intersect. The composition of the CPP was determined by X-ray
diffraction analysis using a Rigaku Mini Flex 600 diffractometer.
Based on the results obtained, the design of an energy-saving trench-type double-slope solar
greenhouse was modernized. Experiments were carried out to determine the thermal parameters
of a trench-type solar greenhouse without the use of traditional fuels. The temperature regimes,
relative humidity of solar greenhouses with one- and two-layer CPPs were studied under warm
(December 7-8, 2022) and cold (January 12-13, 2023) weather conditions. The experiments showed
that on frosty days (January 12-13, 2023) the night temperature of the air in a trench-type solar
greenhouse with single-layer and two-layer film coatings, respectively, was -2 0С and 2.10С.
