ABSTRACT:
A method and apparatus for measuring an unknown quantity of heat in a measuring zone formed by a vessel of good thermal conducting properties is carried out in such a manner that the measuring zone is supplied with a known quantity of heat and the quantity of heat of the measuring zone is given off to a cold zone, that the temperature of the measuring zone is always kept equal to the temperature of the environment and at the same time the dissipation of heat is kept constant by keeping the difference between the temperature of the measuring zone and the temperature of the cold zone always the same, and that the known quantity of heat supplied to the measuring zone is measured at a point outside of the vessel when the unknown quantity of heat is absent and when it is present, the difference between the known quantity of heat in the absence of the unknown quantity of heat on the one hand and the known quantity of heat in the presence of the unknown quantity of heat on the other hand being the measurement result for the unknown quantity of heat. The vessel includes a known heat source and a cold source is provided which is connected with the vessel by way of a heat-conducting element.
