Basing the fuel saving and environmental performance of solar air heater collectors

Abstract

In the article, the thermal energy balance of a laboratory-research room with a total area of 30 m2 and a volume of 60 m3 is compiled. The research was conducted on January 5, 2023. Coordinates of the research site Latitude - N = 40.42584°, Longitude - E = 71.76826°. Azimuth angle 119.85 degrees at sunrise time 738 hours was 1218 hours. When the heat balance of the laboratory-research room was drawn up, the external temperature decreased from -2 °C to -12 °C, correspondingly, it was observed that the heat loss of the laboratory-research room was from 7,8 kW to 10,6 kW. The reason for the sharp increase in energy consumption was that the house was built without meeting the standards of heat dissipation. In order to reduce energy consumption, a solar air cooler collector was installed on the side of the laboratory-research building and the results were obtained. As a result of the installation of a solar air heater collector with a working surface of 1 m2, it was experimentally determined that the daily energy consumption is reduced by 1,43 kW.
