The present paper overviews heat storage materials (HSM) with phase change
based on organic compounds. They consist of paraffin, brown-coal wax and polyethylene
wax. These materials are produced on an industrial scale for the foundry work. It is shown
that heat capacity of HSM in the solid and liquid states can be used for heat storage in addition
to the heat of phase change. The results of investigations of phase change during heating
and cooling HSM are presented. The studies are carried out by differential scanning calorimetry
(DSC). The measurement techniques of the specific heat capacity and the coefficient
of thermal conductivity are shown. Temperature dependences of the specific heat capacity of
HSM in the solid and liquid states are researched by DSC. Values of the coefficient of thermal
conductivity are determined by contact stationary technique of the flat plate over the entire
temperature range of the operation of heat storage system. |
