| Summary: | The analysis of heat exchange processes during cooling of the heated surface of the process equipment
is carried out on the basis of the equations contained in the ANSYS Fluent package. When modeling
heat exchange processes, the following boundary conditions are adopted: the temperature of the
heated surface; the coil heat exchanger is located at a distance from the heated surface of the process
equipment.
From these results, we can draw the following conclusions: the increase in the temperature of the
heated surface leads to the increase of the heating zone of the refrigerant with high capacity and,
hence, to increase heat capacity; increasing the refrigerant flow rate, the lower the temperature of
the refrigerant at the exit, but increases the thermal capacity; increasing the pressure of the heated
refrigerant increases the thermal; this design of the heat exchanger allows you to achieve the necessary
power for the operation of the drive by: changing the flow rate of the refrigerant, the excess pressure
of the refrigerant, the number of elbows, as well as by installing a heat-reflecting casing |
