Abstract

The system is used for measuring the thermal conductivity of bodies, and may determine the rate of heat flow through the bodies and the amount of heat stored in the bodies. There are two containers one inside the other. The outer container or mantle, contains a heater whose output may be regulated. It may be used as a guard ring, being switched to meet at the same temperature as the inner container. The inner container is used for the actual measurement when equilibrium conditions have been reached.

Description

Meßgerat zur Bestimmung von Warmedurchlassigkeit,Measuring device for the determination of thermal transmittance,

Warmedurchgang und Warmespeicherung von Körpern.Heat transfer and heat storage of bodies.

Beschreibung: Das Gerät besteht aus zwei ineinander geschachtelten Behältern. Der innere Raum, das Kernmeßgerat ist mit einer konstanten, beKannten Wärmequelle versehen. er übergestülpte zweite Behälter, das Mantelgerat, enthalt eine regelbare Wärmequelle, die über eine Schaltung hier immer dieselbe Temperatur wie im Kernmeßgerat schafft.Description: The device consists of two nested ones Containers. The inner space, the core measuring device is with a constant, known Provide heat source. it contains a second container, the jacket device, which is placed over it a controllable heat source that always has the same temperature via a circuit as in the core measuring device creates.

tie meßung des Wärmedurchgangs erfolgt, indem das gesamte Gerät mit der offenen Seite gegen das bauteil, b.z.w. den Körper gehalten wird; die Energiequelle wird eingeschaltet, und nach erreichen einen konstanten Temperatur im Kernmeßgerät, kann man ei über den Temperaturunterschied zwischen Kernmeßgerät und Gegenseite des Bauteiles den Wärmedurchgang durch den Querschnitt des Kernmeßgerätes direkt errechnen.The heat transfer is measured by using the entire device the open side against the component, e.g. the body is held; the energy source is switched on, and after reaching a constant temperature in the core measuring device, one can find out about the temperature difference between the core measuring device and the opposite side of the component the heat transfer through the cross-section of the core measuring device directly calculate.

Die Schwierigkeiten der Meßung auf diesem Gebiet, ta die in den Warmeverlusten sowohl auf Seiten des Gerätes, als auch in der seitlichen Erwärmung der Wand lagen, werden beide durch den Einsatz des Mantelgerätes beseitigt.The difficulties of the measurement in this area are due to the heat losses both on the side of the device and in the lateral heating of the wall, both are eliminated by using the jacket device.

Die Meßung der Wärmespeicherung erfolgt über die beit, die benötigt wird, um eine konstante Temperatur im Kernmeßgerät zu erhalten.The measurement of the heat storage takes place via the beit that is required to maintain a constant temperature in the core meter.

Das von mir erfundene und beschriebene Gerät ermöglicht es, auf einfache Weise in bestahenden Gebauden den k-Wert und die Wärmekapazität der Bauteile zu ermitteln.The device that I have invented and described makes it possible, in a simple Assign the k-value and the heat capacity of the components in existing buildings determine.

Exakte Ergebnisse können geliefert werden, wenn auf der Gegenseite des Bauteiles die Temperatur konstant gehalten wird.Exact results can be delivered if on the other side the temperature of the component is kept constant.
