US 10,541,357 B2 · Method and device for cyclical operation of a thermoelectric cell arrangement

Abstract

The invention relates to a method for cyclical operation of a thermoelectric cell arrangement by periodically changing the temperature of the thermoelectric cell arrangement, wherein the thermoelectric cell arrangement is thermally coupled to a cyclically operated absorption heat pump. The following method steps are carried out cyclically: thermally coupling the thermoelectric cell arrangement during a cooling phase to a cold side of the absorption heat pump, thermally coupling the thermoelectric cell arrangement during a heating phase to a hot side of the absorption heat pump. The invention also relates to a harvester device for generating electrical energy by means of a thermoelectric cell arrangement, wherein the thermoelectric cell arrangement is thermally coupled to an absorption heat pump, wherein the thermal coupling makes it possible to effect, in time with the working cycle of the absorption heat pump, a temperature change in the thermoelectric cell arrangement.

A method for cyclically operating a thermoelectric cell arrangement, that is thermally coupled to a cyclically operated sorption heat pump, which comprises the step of:

periodically changing the temperature of the thermoelectric cell arrangement, which comprises the sub-steps of:
lowering the temperature of the thermoelectric cell arrangement by thermally coupling the thermoelectric cell arrangement during a cooling phase with a cold side of the sorption heat pump, whereby due to a lowering of the temperature charge separation with a first polarity takes place within the thermoelectric cell, and
increasing the temperature of the thermoelectric cell arrangement by thermally coupling the thermoelectric cell arrangement during a heating phase with a hot side of the sorption heat pump, whereby a temperature increase leads to a renewed charge separation with a second polarity within the thermoelectric cell, the second polarity being opposite the first polarity,
wherein electrical energy is generated by cyclically performing the steps of lowering the temperature of the thermoelectric cell arrangement and increasing the temperature of the thermoelectric cell arrangement.
