A calorimetric sensing device is suitable for measurement of thermal energy consumption and consist from the metal calorimetric body (1) with defined cross-section, equipped with heat-conducting ring (11) on inlet, with the first and the second inner temperature sensing elements (2, 3), which are placed on the calorimetric body (1) in defined distance and with the cooler (12) with defined cooling surface on the outlet. The calorimetric body (1) up to the cooler (12) is embraced by thermo-insulating layer (5), with cover (6) on which is placed external sensing element (4). The first and the second inner temperature sensing element (2, 3) and the external sensing element (4) are connected by measuring traces (7) with the evaluating unit (8). The calorimetric sensing device enables to take in consideration at the final calculation of the thermal energy consumption the instantaneous changes of convection conditions as well as changes of the heat transfer coefficient, changes of moisture and the changes in mass of heated air. Thehigh accuracy of measurement is achieved. |
