Prospects for using polymer ceramic composite films in solar engineering and agriculture
Abstract
Data are presented on the increase of the temperature by 15°C with the use of a film containing 1% of a functional ceramic, and the evaluation of the economic effectiveness of the heated agricultural facilities and the various solar heating and drying systems with the transparent enclosures upon replacing the conventional film or glass with this composite material. The energy savings thanks to the use of the ceramic are 288 000 euros/ha, the crop yield increases by 35% or 21 tonnes/ha, the reduction of the energy consumption for the same productivity is 288 000 euros/ha or a total of 3556 to 4800 million euros per year; the additional income plus the energy savings amounts to 298 500 euros/ha. The payback time in terms of the income plus the energy savings is 0.0101 to 0.0109 year.
