Process and control system for a reversible heat pump including thermoelectric modules

摘要

The system has an electric supply unit (10) connected to an electric current source (8), where the supply unit comprises output connections (S1-S4) for delivering supply voltage to heat transfer thermoelectric units (41-44) e.g. Peltier effect cell. A control device (6) is connected to switches, where the control device controls different switching configurations of the switches for selectively powering the thermoelectric units and selecting supplying of predetermined voltage level to the thermoelectric units. Independent claims are also included for the following: (1) a thermoelectric reversible heat pump comprising an exchanger (2) a method for controlling a thermoelectric reversible heat pump.
