A device for measuring the integrale with respect to time of a overtake of temperature and the application to the control of the heating of a building

摘要

The invention relates to a device for integrated measurement with respect to time of the exceeding, with respect to a reference temperature, of the temperature of an enclosure in which the said device is placed, of the type comprising a container 1 divided by a liquid-permeable means 4 into two compartments 2, 3 and in which there is placed a substance 5 which has the said reference temperature as its melting point. The volume of the said container is completed by a second substance 6 whose melting point is less than the said reference temperature and whose density is different from the density of the first substance.
