摘要

Theoretical studies of the thermal state of heat storage elements with air channels of various shapes in the modes of charging and heat output of the electric thermal storage (ETS) are carried out. The mathematical model of heat exchange processes adapted to the operating modes of the ETS is presented. The change in the average heat transfer coefficient in the air channels in the conditions of natural and forced convection in the modes of charging and heat output ETS, and the heat flux density in the mode of charging of the ETS from a tubular electric heating element (TEH) for heat storage elements with channels of a slit and round shape are shown. The temperature distribution in heat storage elements made of chamotte and magnesite with slit-shaped (standard design) and round shape channels is obtained. As a result of the studies carried out, the temperature change and the dynamics of heat transfer in the air channels of heat storage elements made of various types of thermal storage material (TSM) in the modes of charging and heat output of the ETS were analyzed. The conclusion is made about the efficiency of using heat storage elements made of chamotte with round-shaped channels in the ETS.
