METHOD OF CONSTRUCTION OF THE TEMPERATURE FIELD IN VOLUME OF THE PREMISE

The knowledge of a temperature field in volume of a premise is necessary at the analysis and researches of parameters of a microclimate, dynamics of a temperature mode of a fire, a condition of technological thermal process, etc. There are various methods of definition of a spatial temperature field of the gas environment in a premise. The most effective method is the method in which as gauges the thin plates possessing constructive simplicity are used. Thus the assumption is done, that the temperature of a surface of the gauges placed in control points is practically equal to temperature of the gas environment these points. The temperature of a surface of gauges is measured nonconductor with the help of a pyrometer. The offered assumption proves to be true mathematical model of heating of a thin plate in the gas environment of the set temperature. The equation of heating of a plate is received, and on the basis of this equation it is possible to define borders of an error of the measured temperature in control points. The value of this error depends on thickness of the gauge: the less thickness, the less value of an error, which can be taken temperature in control points fastly and more precisely.
