What is Samsung WindFree technology?
Unlike conventional air conditioning systems that blow cold air directly into a room, Samsung WindFree technology is designed to distribute cooled air gently through thousands of tiny micro-holes in the indoor unit's front panel.
Once the room reaches the desired temperature, WindFree mode can maintain comfortable cooling with minimal noticeable draughts.
It's particularly useful in bedrooms, where direct cold airflow can be uncomfortable while sleeping.
Samsung WindFree features
WindFree Cooling
Enjoy gentle, draught-reduced cooling through thousands of micro-holes rather than a strong stream of cold air.
Smart Wi-Fi Control
Control compatible Samsung WindFree units using the Samsung SmartThings app.
- Turn the air conditioning on or off remotely
- Adjust the room temperature
- Change operating modes
- Create schedules and routines
- Manage compatible connected devices
Quiet Operation
WindFree cooling is designed to minimise noticeable airflow and reduce disturbance, making it ideal for bedrooms, home offices and living spaces.
Fast Cooling
Use conventional fast cooling to bring the room temperature down quickly, then switch to WindFree mode to maintain comfort more gently.
Heating and Cooling
The system works as an air-to-air heat pump, providing cooling in summer and efficient heating during colder months.
Energy-Efficient Inverter Technology
Samsung's inverter technology adjusts compressor operation according to demand, helping to reduce unnecessary energy consumption compared with fixed-speed operation.
Independent Room Temperature Control
Each indoor unit has its own controls, allowing different temperatures and fan settings in the two rooms.
Both indoor units share the same outdoor condenser and must operate within the system's supported heating or cooling mode.
Modern, Discreet Design
The Samsung WindFree indoor units feature a clean, contemporary appearance that complements modern bedrooms and living spaces.
