Energy saving using solar air heater collectors

Abstract

In this study, the issue of providing heat energy to a small utility room from a solar air heater collector in the climate of Uzbekistan was considered. A diamond-shaped heat exchange accelerating element is used in the installed solar air heater collector. The total working surface is 1 m2. After installing the solar air heater collector, the thermal energy balance of the service room was compiled. As a result, it was determined that 81355 W of thermal energy is required during the day to maintain the room temperature at a normal level. The amount of heat required for the sunny time of the day was 28873 W. The amount of heat received from the solar air heater collector was 1350 W. As a result of the calculations, it was found that the total working surface is 21 m2 on average to provide 100% of the required amount of heat in sunny weather with the help of a solar air heater collector. The calculation process was carried out for 06.01.2023. Covering the daily amount of heat required by the consumer with the help of a solar air heater collector is considered very complicated and requires a lot of money. Therefore, during the design of the heat supply from the solar air heater collectors, it is appropriate to determine the average amount of heat for the season at 15-20%.
