The paper discusses ways to improve the energy efficiency of solar collectors. Constructive, technical and operational methods are considered. The purpose of the work is to determine the effectiveness of the application of certain methods. The work evaluates the rationality of methods for various uses (hot water supply, heating, etc.). A mathematical and computer model for calculating solar collectors has been built, methods for assessing the energy efficiency of the system have been determined. Comparative analysis of calculated data with experimental data is carried out. The dependence of the temperature of the heat-transfer fluid in the circuit on the type of fluid, the angle of inclination of the collector and the flow rate in the system is determined. Practical recommendations for the operation of similar systems in general and for the northern regions of Europe have been compiled. |
