At the heart of these systems is a crucial component: the power electronics. It controls the flow and conversion of electrical energy and ensures that living spaces are kept at a pleasant temperature at all times of the year. Of central importance here is the inverter, which converts direct current (DC) into alternating current (AC) to drive the compressor and the circulation motors. This enables precise control of the compressor speed and fan power - crucial for maintaining efficiency and meeting different heating or cooling requirements.
