Novakivsky E. Increasing of efficiency of use solar energy in the combined industrial systems of heat supply

The thesis deals with the theoretically and practically proved technical opportunity of creation of the combined system industrial systems of heat supply that based of solar “delta – system” prefixes for boiler. The analysis of different techniques of estimation of instant efficiency of usual solar collectors and solar “delta–system” prefixes is carried out. The analysis of long-term characteristics of solar “delta–system” prefixes and usual solar collectors is carried out. Practical salvations that concerns structure of combined system of heat supply are offered. Hourly mathematical modeling of energy efficiency of usual solar collectors and solar prefixes for boiler, modeling of replacement factor for warm months of the year my means of Visual Basic are determined. Energy characteristics of solar prefix in view of regimes of work of solar collectors at long-term work of system are determined. Recommendations of optimum designing of usual solar collectors and solar “delta- system” prefixes for boilerinstallations as a main structure elements of combined industrial heat supply system are offered. The technique, algorithms and programs of numerical modeling of thermal processes in combined systems of heat supply are developed.
