THERMAL NON-DESTRUCTIVE TESTING METHOD OF RESISTANCE TO HEAT TRANSFER OF BUILDING STRUCTURE Russian patent published in 2013 - IPC G01N25/72 

FIELD: heating.

SUBSTANCE: on both sides of the building structure there installed opposite each other are flat heat insulated boxes with flat thermostats having linear sizes of three to five thicknesses of the building structure, which are located at the specified distance parallel to its surfaces and heating them to unequal temperatures between each other; density of heat flow passing through the building structure, as well as temperatures on both surfaces of the building structure, are measured at the specified time interval, differing by the fact that there controlled is resistance to heat transfer in relation to temperature difference of thermostats to density of heat flow after the specified heat release of surfaces of the enclosing structure is determined by adjustment of speed of air flows inside boxes.

EFFECT: providing the possibility of controlling resistance to heat transfer under conditions of equality to normalised values of heat transfer coefficients of surfaces of the tested building structure.
