EXPERIMENTAL INVESTIGATION OF THE HEAT CONSUMER OF A LABORATORY SOLAR THERMAL INSTALLATION
Abstract
In this paper, the main heat exchange parameters of the heat consumer of a laboratory solar thermal installation are investigated. The heat consumer is a water-air convector, composed of a total of six two-rows staggered finned tube bundles. The research is carried out under certain operating parameters of the solar installation. The internal heat convection coefficient is calculated according to a criterion equation. The external heat convection coefficient is calculated according to a certain formula, depending on the velocity of the air flowing the heat exchange surface. The overall heat transfer coefficient is calculated by neglecting the thermal resistance of the walls of the tubes and the fins.
