Název v původním jazyce

Thermography Data of Panel Radiator Dynamic Behaviour for Simulation Model

Popis výsledku v původním jazyce

Article deals with monitoring, analysis and description of the thermal dynamics of panel radiator outside thermally steady state. Simulation could be based on these evaluated data. Radiator was observed by infrared camera mainly in the heating-up phase, i.e. when the initial temperature balanced state is changing into a nominal temperature state. However cooling phase was observed too. Research is based on changing of temperature fields’ layout on frontal heat transfer area. According to the thermography pictures of the front plate and assessment of whole process could be developed a mathematical model in e.g. Matlab Simulink. Dynamic model in this software environment will be able to describe and generate heat-up and cool-down phases and their combination (i.e. real dynamic behaviour) for specific radiator and its transition states. Knowledge and the ability of simple generation of thermal inertia will be beneficial both for manufacturers of radiators and for designing an appropriate way of controlling. Inputs for mathematical model are experimentally evaluated values of dead time, process delay, process reaction rate, time constant and speed of response, as a dynamic variables describing speed of change of thermal states, and a radiators manufacturer data. The relationship of variables to the geometry of a radiators body and the dependence of their changes in time are also described. Future goal of this model is the ability to evaluate transition states for different types of radiators with using a minimum experimental data.
