## Key points

- Smart ACs use sensors to direct cooling towards people.
- Samsung claims up to 30 per cent energy savings.
- The actual savings from these features remain unclear.

## Summary

Air-conditioning is a major source of electricity use and emissions, and demand is expected to grow sharply as more homes, workplaces and schools need cooling. Manufacturers are adding radar, cameras and AI to direct cool air towards people and adapt to their routines, with the aim of improving comfort while using less energy.

The article describes systems from LG, Hisense, Samsung, Dyson and Midea, including LG’s five-metre radar sensor and Samsung’s claimed savings of up to 30 per cent when its AI energy mode is on. Some devices can track occupants or use wearable data to adjust airflow; others learn patterns or map rooms. The potential energy savings remain uncertain, and the article also points to compact heat pumps and climate-safe refrigerants as part of a broader response to rising cooling demand.
