METHOD AND DEVICE FOR MEASURING HEAT FLOW THROUGH OBJECTS Russian patent published in 2016 - IPC G01K17/20 G01N25/18 

FIELD: construction.

SUBSTANCE: invention relates to construction heat engineering and can be used for measuring heat flow through a structure. Structure has thickness (D), at which in cross direction temperature (ΔT) difference is formed. According to invention at least two temperature sensors (G1, G2) are installed on first surface (S1), wherein at least one of them, for example, first sensor (G1), is heat-insulated from second sensor (G2). As a result temperature (T1′), detected by heat sensor (G1), is influenced by heat flow passing through structure (K) to a greater degree than temperature (T1″), detected by second sensor. Method includes determining difference of temperatures (T1″-T1′) between second sensor (G2) and first sensor (G1), after which energy is supplied to first sensor (G1), heating first surface in area surrounding said sensor, thereby reducing said difference. Then, based on amount of applied power (E_Q), determining as function of temperature difference (Δt), heat flow (J) passing through structure.

EFFECT: technical result is higher accuracy of determination for a specific structure of heat transfer coefficient.
