Abstract

In the conditions of autonomous functioning of special equipment, there is a need to use its internal sources. This can be accomplished using a heat recovery system of the internal combustion engine. For this purpose, the authors suggest a heat accumulator. The mathematical modelling of the thermal state of the heat accumulator in the cooling stage is done. The main factors affecting the cooling time of the thermal accumulator are the thickness of the insulation of the heat accumulator, the mass of coolant, coolant temperature, air temperature, wind speed. The authors also developed a mathematical model of the cooling process of the heat accumulator in a general way. It is presented in graphical form, which makes it easier to determine the time of cooling the heat accumulator in the process of its designing. For automatic calculation, an algorithm has been developed and implemented in the program to determine the dimensionless temperature and criterion Bio.
