Abstract
The invention refers to a device to measure thermophysical characteristics - thermal conductivity factor and specific thermal capacity of building encasements (walls) . Measurement is made in a dynamic non-destructive mode, with the possibility to be carried out on walls of existing buildings. The device comprises thermostable thermal cameras (1,4) providing for predefined thermal currents, thermal sensors (12,13) to measure the temperature of the wall, sensor (16) of the actual power fed to the heater, real timer (17), a computer (18) and a comparator (19). Evaluation of thermophysical characteristics is made by comparing the recorded encasement temperature curve recorded in the memory (15) to the temperature curve calculated from wall simulation by the computer (18). The device is especially suitable for evaluation of thermophysical characteristics of existing buildings without any damage to them.
