Abstract:
A device for determination of heat transfer characteristics through an arrangement of at least one plate-like sample affected by various types of heat which consists of two chambers R1 and R2 of equal size separated by the sample arrangement and supplied with heating and cooling equipment in order to heat or cool the air in chamber R1 continuously as well as in form of cycles, surface heaters in order to provide radiant heat as well as conductive heat exposure, a ventilation system producing an air stream which flows over the front of the sample arrangement and PT 100 temperature sensors for temperature measurements as well as infrared sensors for heat radiation measurements and where the sample arrangement is separated from chamber R1 by a diaphragm to avoid heat transfer through the sample arrangement prior to the test and that this diaphragm is removed from the device through an opening in the device cover.
