Název v původním jazyce

Dynamic behaviour of the panel radiator

Popis výsledku v původním jazyce

This article deals with the monitoring, analysis and description of the thermal dynamic processes of a panel radiator outside the thermally steady state. Analysis is based on the layout of the temperature fields on the frontal heat transfer surface of radiator. Surface was monitored by thermal camera. It is focused on the specific panel radiator - Korado Radik Classic type 10 with dimensions 500 x 1000 mm with a single side connection to a heating system from the top to the bottom. Heating appliance was observed only in phase of heat-up, i.e. stage of increasing of heat output. The thermography image of the whole front panel of the radiator was divided into 9 equal areas. In each of those sectors were graphically found dynamic variables describing rate of change of thermal state: dead time (or transport delay), process delay, process reaction rate, time constant and speed of response. The relationship of these values relative to the geometry of a radiator body and the dependence of their changes in time are also described in this paper. Article draws and further deepens knowledge arising from experiments performed at the Department of environmental engineering.
