Thermal Engineering and Technical-Economical Indicators of Seasonal Flat-Plate Capacitive Solar Water-Heating Collectors

The article presents the results of field experiments to determine the thermal and technical and economic indicators of flat capacitive solar-water heating collectors made of translucent plastics with bottom absorption of solar radiation for seasonal use in the regions of the Republic of Uzbekistan. As follows from the results during the warm season, the seasonal thermal efficiency in the reservoirs under consideration, depending on the thickness of the water layer for the season, respectively, is 17% at 0.05 m and 24% at 0.07 m. At the same time, the specific savings for natural gas from the Shurtan deposit and Angren coal deposit are 488 Nm3 and 910 kg per season, respectively. The reduction of CO2 emissions during the season during the combustion of natural gas from the Shurtan deposit is 667 kg and Angren coal deposit (depending on the percentage of carbon in the composition of coal) from 3148 to 4814 kg of CO2, respectively.
