Device and method for thermal measurements on walls

Abstract

Abstract 1. Method for measuring the coefficient of thermal transmission K of a wall, from a measurement of the thermal flux and a differential measurement of temperature on either side of the wall, characterised by the following operations : a) repetitively measuring the ambient temperatures Tae , Tai on each side of the wall, b) at the same time measuring the thermal flux vphi passing through an area of pre-determined contour (F) on one side of the wall, c) determining the ratio SIGMA vphi/SIGMA DELTA T of the cumulative thermal flux to the cumulative temperature differences DELTA T = Tae -Tai , and d) continuing the operations a) to c) until the said ratio tends towards a substantially constant value.
