Non-stationary temperature field of the heating device in the conditions of unsteady thermal field of the space

Abstract

The trend of the modern world is aimed at improving the energy efficiency of buildings and reducing unnecessary costs of heat and electricity. In view of this, heating systems are used with a periodic operating time, in order to reduce the cost of heat energy during periods of absence of people. As a result, this paper will consider a method for determining the temperature of a heating device, taking into account the heat accumulation by the metal body of the device and the heat carrier inside it, with changing environmental parameters, which will allow taking into account the accumulated heat during the heating system operation.

Solution of Thermal Conductivity Problem of a Finite Dimensions Plate with Two Heat Sources

“…In this regard, thermal panels are quite complex objects from the point of view of mathematical description, and each of their designs is actually a special case. A review of modern works on this issue showed that to determine the thermal characteristics of thermal panels, the solution of analytical equations is rarely used, and, as a rule, exclusively for solving the problem of radiation heat transfer [11][12][13][14]. The method of numerical modeling [15][16][17][18], experimental studies on finished samples [19][20][21], and in some cases a combination of numerical modeling and experimental research [22] are used more often.…”
