Outdoor system makes WindFree™ units even more “wind-free,” helping spread its comfortable cool to every corner of the space

Samsung Electronics announced the global launch of its new DVM S2 Variable Refrigerant Flow (VRF) outdoor air conditioning unit that works with indoor units to provide exclusive WindFree™ Cooling everywhere without the discomfort of direct cold airflow when indoors.


“DVM S2’s efficient yet powerful performance exhibits how Samsung’s exclusive WindFree™ Cooling technology continues to advance,” said Young June Choi, Head of Air Solution Biz Group of the Digital Appliances Business at Samsung Electronics. “This AI-controlled system is Samsung’s most advanced climate control solution yet, set to bring WindFree™ comfort to apartment blocks, small to midsize office buildings, and commercial buildings everywhere.”



DVM S2, Samsung’s sixth-generation Digital Variable Multi air conditioner, incorporates an outdoor-installed system for enhanced flexibility and functionality. It enables connection with up to 64 Samsung indoor air conditioning units for optimal comfort without unpleasant cold drafts. Compatible with Samsung’s 1Way, 4Way, 4Way 600×600, and wall-mounted models, DVM S2 is currently available in Europe and slated to be available in China in July 2021, followed by the Middle East, North America, and select markets in Asia.



Wider Frequency Range for Better WindFree™ Performance

The DVM S2 features innovative technologies including a more advanced scroll compressor with Advanced Flash Injection (AFI) technology, an enlarged heat exchanger with optimized refrigerant flow, a multi-serration fan, and an enhanced power module.


The more advanced AFI motor control technology allows for a wider frequency range of 10~180Hz. The new low of 10Hz (compared to the previous model’s 14Hz) making the system more stable at low frequencies, leading to better WindFree™ performance for draft-free, comfortable temperature control. The new high of 180Hz ensures more powerful cooling performance.



Bigger Heat Exchanger and Multi-Serration Fan

Compared to the same capacity models in the current DVM S series, the heat transfer area of the heat exchanger in all the new models are significantly larger. The new unit’s hybrid path is designed to optimize the refrigerant flow corresponding to the airflow profile. Moreover, its unique multi-serration fan minimizes the turbulence of the air vortex, applying different serration, considering the air velocity of the edge and the inside of the blade, respectively. Moreover, the highly efficient Insulated Gate Bipolar Transistor (IGBT) reduces the loss of conducted electricity.


DVM S2’s new design is more aerodynamic and allows quieter operation, compared to previous generations. It has a more robust frame and reinforced structure with an upgraded exterior cabinet for reliability. The cooling operating range and external static pressure have been extended for flexibility in design, along with an upgrade on the emergency operation mode. Moreover, DVM S2 also features an on-device inverter check for better maintenance. Advanced technology for refrigerant sub-cooling control and installation condition analysis allowed for a smaller liquid pipe, which provides a 28% reduction in the amount of additional refrigerants used during installation compared to its predecessor.




AI Capabilities for Smarter, Faster Cooling

Thanks to its AI capabilities, DVM S2 detects indoor climate conditions to deliver optimized cooling and heating performance. AI Low Pressure Control learns the patterns of cooling operation and reaches the target temperature more rapidly, ensuring users in the room feel more at ease at the desired temperature. Meanwhile, AI High Pressure Control maintains the optimal high pressure by making adjustments based on the installed environment. AI Defrost Control provides the best timing for defrost operations, and hence offers increased comfort during heating. In addition, DVM S2’s advanced AI algorithms can detect refrigerant leaks in real-time and send alerts immediately so users can monitor and manage their units quickly without compromising comfort.
