摘要：Problem statement.All heat-proof materials can be divided into homogenous – low thermal conductivity (foam,foams,etc.),and composite,laminated – with the presence of mineral media having different thermal characteristics showed the analysis ,but in an amount giving a beneficial effect in the presence of thermal insulation of the predominant proportion of radiant body.Studies have shown that in the presence of an equal distribution of the volume of air mass takes place largely pin and convective heat transfer.The analysis methods for determining the thermal properties of materials and their means of measurements showed that the majority of them based on solving the problems of transient heat conduction with heat sources,the geometry of which is not reflected in the calculation formulas.Therefore,a measurement method that allows to determine the thermal performance of building materials walling according to experience directly in a production environment.Purpose – to perform theoretically study the development and application of sensors with ring heater for the determination of thermal properties of building materials walling,which will assess the indoor climate changes,taking into account changes in the environment.Conclusion.The method of solving the problem with the annular heat source results in analytical functions describing the change of the temperature field of the array with the initial and boundary conditions,geometry and thermal power sources.It may naturally be generalized to problems with variable power heat sources,as well as inhomogeneous and isotropic bodies having different thermal performance.Ultimately,as a result of the research we have obtained to determine the dependence of thermal characteristics of the materials studied.On the basis of the calculated dependences we have proposed a sensor,with which,in addition to determining the thermal properties of materials,it is possible to investigate the heat transfer of building structures with the environment in a confined space.At the same time we adopted a functional block diagram of the sensor with a ring heater that allows to evaluate the changes of thermal properties of building materials during the operation.
