ROOM THERMAL LOSSES DETERMINING METHOD AND DEVICE Russian patent published in 2018 - IPC G01K17/20 F24D10/00 

FIELD: measurement technology.

SUBSTANCE: invention relates to the field of thermometry and can be used to determine the room heat losses coefficient K. Claimed method of the room heat loss coefficient K determining comprises the stages, at which in a room applying the heating power P_k of the room for two consecutive time periods (D_k)k=1 or 2 and performing works to measure at least the temperature T_ik inside the room at short intervals, and also determining the outside air temperature T_ek at short intervals. At that, the heating power P₁ for the first period D₁ is such that the next parameter (α) was less than or equal to 0.8, while the heating power P₂ for the second period of time D₂ is substantially zero. For each time period D_k selecting the time interval Δt_k, at which the T_ik(t) change is substantially linear. For each time interval Δt₁ and Δt₂ determining the α₁ slope or the α₂ tangent to the curve T_ik(t). Based on the α₁ and α₂ slopes outputting the K_calc value of the room heat loss coefficient K.

EFFECT: higher accuracy of obtained data is provided.
