Comparative Characteristics of the Developed Electric Heat Exchanger Regulators to Obtain the Energy of Water-Ice Phase Transition

Abstract

The authors have developed electric regulators: relay-pulse ones, with solid filler and electric heater, with solid filler and thermoelectric module, for a heat exchanger to obtain the energy of the water-ice phase transition. Experimental studies were carried out, the static and dynamic characteristics of electrical controllers were determined to determine the most fast-acting regulator. They substantiated that after the use of the thermoelectric module, the regulator operation is ensured during potato storage heating and cooling. Moreover, when they change the potato storage operating modes by changing the polarity of the thermoelectric module, the speed of the regulatory body is ensured. The heating efficiency of the solid-filled electrical regulator and thermoelectric module is higher than of electrical regulator with solidfilled electrical controller and electric heater.
