| 摘要 |
The invention relates to the area of measuring of heat that is liberated or absorbed at physical-chemical and biological processes, at scientific investigations, in power engineering, chemical, food, microbiological industry. A calorimeter of heat flow includes calorimetric sensitive shell mounted to thermostatically controlled block and a cell with reaction vessel placed there, and measuring-computation system. Coaxially to the main calorimetric shell an additional compensation calorimetric shell is placed, this has diameter, design and compactness of thermo-elements same to those of the main shell, and height of the shell is 2…10 times smaller, at that in compensation shell simulator of cell and reaction vessel is placed, this has specific heat capacity per unit area of the surface of the shell same to that of the content of the main shell. Between the main and compensation calorimetric shells heat screen and layers of heat insulation are placed. Simulator of the shell and reaction vessel placed in additional compensation shell is arranged as component, and between the parts that form the simulator controlled thermal resistances are placed. The technical result of the invention is in increase of accuracy of measurement of heat that is liberated or absorbed in physical-chemical and biological processes. |
