Abstract
A phase change heat storage device for an active thermoelectric heat pump was
tested for its heat storage and release performance at different operating
voltages and heat source temperatures. A study on heat release/discharge
characteristics of a phase active heat exchanger is proposed. The
experimental results show that there are significant differences in
heating/discharging time and operating performance of the device under
different operating conditions and heating conditions. When the operating
voltage is high and the temperature of waste heat is high, the heating time
of the device is short. Continuing to increase the voltage efficiency during
this period will increase the temperature difference between the cold and
hot ends of the semiconductor chip, decrease the heat coefficient of the
device. Compared to passive phase change heating equipment, the best way of
this equipment is to adjust the voltage. Adjusting the operating voltage in
a suitable manner can maximize its heat/discharge efficiency, while
overcoming the shortage of heat-supply equipment in low voltage secondary
heat storage systems, and cannot improve the inequality between supply and
demand in terms of time, position, and energy.
