dc.description.abstractAccurate calculations of radiator thermal performance were performed based on accurate considerations of the varying heat transfer coefficient on the radiator surface. Using a reference point, both the main equation for heat power output and the main equation for exit temperature were derived. Both equations allow the prediction of all other operating points, so that the complete thermal characteristics of a given radiator can be calculated directly from the reference point without having to consider the geometrical parameters of the radiator and the physical properties of the air under free convection. For performing the load regulation with the exit flow temperature as the target, e.g., reverse calculations for the exact setting of the mass flow were presented. Furthermore, the approaching equation contained in DIN EN442 was reviewed for its accuracy and application limitations. For designs and calculations, both the eigen-constant and the eigen-parameter were furthermore introduced, which greatly facilitates the experimental determination of the heat transfer coefficient. The established relationship between the power output and the surface area of radiators showed satisfactory agreement with the data available in the VDI Heat Atlas.de_CH
