Abstract

The device has a measurement element (M) permitting to simultaneously record an ambient temperature (TA) of a room, an external temperature (TE) and an inner surface temperature (TS) of a considered wall. The element integrates a surface thermal resistance value according to a direction of a heat flow and the nature of an external environment, and considers a mean surface temperature of the wall by scanning the wall surface. A calculator of the element permits to calculate and display a thermal coefficient (U) value by using a formula with temperatures (TE, TS, TA) and the resistance value.

Description

-1- La présente invention concerne un dispositif permettant de mesurer leThe present invention relates to a device for measuring the

flux de chaleur noté coefficient thermique appelé U exprimé en Watt à travers un mètre carré de paroi d'un bâtiment pour une différence de température d'un degré entre les deux ambiances que sépare cette paroi et ainsi définir la performance thermique de la paroi. Traditionnellement, dans le cadre d'une construction neuve ou existante, ce flux thermique est calculé théoriquement en prenant en considération la résistance thermique de chaque élément qui compose la paroi. Mais le flux réel dû à l'imperfection de mise en oeuvre des isolants et des matériaux de construction constituant cette paroi n'est pas mesuré. Le dispositif selon l'invention permet de remédier à cet inconvénient. Le flux de chaleur U est déterminé par la relation suivante : Le dispositif comporte un élément mesureur capable de prendre en compte simultanément la température de surface de la paroi (TS), la température ambiante du local (TA) et la température extérieure ou du local non chauffé (TE). Le coefficient d'échange superficiel de convection 1/hi est fixé quant à lui suivant les règles de calculs réglementaires thermiques en vigueur et diffère suivant la direction du flux. Un calculateur intégré à l'élément mesureur prend en considération la formule et permet de calculer puis d'afficher la valeur du coefficient thermique U.  heat flow noted thermal coefficient called U expressed in Watt through a square meter of wall of a building for a temperature difference of one degree between the two ambiances that separates this wall and thus define the thermal performance of the wall. Traditionally, in the context of a new or existing construction, this heat flow is calculated theoretically taking into consideration the thermal resistance of each element that composes the wall. But the actual flow due to the imperfection of implementation of insulators and building materials constituting this wall is not measured. The device according to the invention overcomes this disadvantage. The heat flux U is determined by the following relation: The device comprises a measuring element capable of simultaneously taking into account the surface temperature of the wall (TS), the ambient temperature of the room (TA) and the outside or local temperature unheated (TE). The convective surface exchange coefficient 1 / hi is set according to the thermal regulation rules in force and differs according to the flow direction. A calculator integrated in the measuring element takes into consideration the formula and makes it possible to calculate and then display the value of the thermal coefficient U.

Le dessin annexé (figure 1) illustre l'invention. Le dispositif selon l'invention est particulièrement destiné dans le cadre de diagnostics de performances énergétiques, d'audits thermiques et de contrôle de mise en oeuvre des isolants des parois d'un bâtiment.  The appended drawing (FIG. 1) illustrates the invention. The device according to the invention is particularly intended in the context of energy performance diagnostics, thermal audits and control implementation of insulators of the walls of a building.
