DEVICE AND METHOD FOR DETERMINING THE THERMAL CONDUCTIVITY AND/OR HEAT CAPACITY OF A WALL

摘要

Device (10) for identifying the thermal conductivity k and/or the heat capacity C of a planar wall, comprising: first and second temperature sensors (A0, AL), placed on the two sides of the wall; a third temperature sensor, delivering a measurement of the ambient temperature neighbouring the first side of the wall; a data acquisition system, for acquiring the measurements delivered by the sensors; and data processing means, able to determine the conductivity coefficient k and/or the heat capacity C of the wall based at least on the information delivered by said sensors in the absence of temperature regulation of or heat flow to one or the other of the sides of the wall. The thermal conductivity and/or the heat capacity are thus determined based only on measurement of easily measured quantities, i.e. surface or ambient temperatures.
