Smart, smaller, more powerful and energy-efficient: Today’s room air conditioning units must fulfill a growing list of demands. Because they are used in private homes, quiet aircon systems are highly sought after. Functions such as stable and smooth starting, a wide range of operating speeds and vibration suppression round out the list of must-haves.

In addition, it must be possible to integrate them easily and securely with a home automation network to support remote control and condition monitoring. Designing room air conditioning units that boast such capabilities requires everything from low vibration components and a low acoustic noise compressor through reliable fan control to sensorless field-oriented control. The enabling semiconductor solutions must also be energy-efficient and reflect new form factors. System solution proposals offer proven integration, comprehensive features, and robust protection while reducing time-to-market. Last but not least, an excellent price-performance ratio is key, as are new features supporting emerging smart appliance designs.
