The next generation
Digital Variable Multi
Rethink your approach to climate solutions with the Samsung DVM S2. It delivers outstanding comfort and high energy efficiency, even in extreme climate conditions. Its intelligent features make installation and maintenance easier and more cost-effective.
Quieter and enhanced heating performance
Advanced Flash Injection Compressor
Experience new levels of comfort. The Advanced Flash Injection Compressor provides tremendous capacity*. It combines Flash Injection technology with a strengthened Triple Profile Scroll and efficient Optimal Discharge Superheat Control technology. It maintains pleasantly cool or warm conditions in every corner of a building all year round.
* Samsung circulates 14,400cc/sec refrigerant (= 90cc (displacement volume) x 160rps (revolutions per second)).
Redesigned to reduce operating costs
Energy Efficiency
Reduce operation costs with a high energy efficiency. The Heat Exchanger has 36.2% more area* to transfer more energy at once. An optimised refrigerant path maximises the transfer rate while minimising any loss. A Multi-serration Fan uses 32% less electricity**. And a new IGBT reduces electricity loss by 20%***.
* Based on Samsung’s measurements, comparing 33.6kW models of a DVM S2 and a DVM S outdoor unit.
** Based on internal testing, using the DVM S2 33.6kW model. A Multi-serration Fan generated 195CMM consuming 725W, while a DVM S fan generated 176CMM consuming 1,057W. Results may vary depending on the individual test or usage conditions.
*** Based on internal testing of the DVM S2 33.6kW model compared to a DVM S outdoor unit, combined with 6 GD2 5.6kW indoor units. Results may vary depending on the individual test or usage conditions.
Active AI Technologies to reduce energy consumption
Active AI Technologies
Optimise cooling automatically. Active AI Pressure Control* intelligently adjusts the condensing pressure, cutting energy use by 35%**. Active AI Defrost increases the continuous heating time by 40%***. And Active AI Refrigerant Analysis**** helps to maintain the optimal amount of refrigerant.
* Optionally available depending on the installation conditions. For detailed information, please refer to the installation manual. 20 % faster cooling based on internal testing of the cooling operation, with the temperature set at 22 °C and using Auto mode for 4 hours, at a room temperature of 33 °C and an external temperature of 35 °C. The tested model was an AM080AXVGGH/EU connected to AM083NN4BHD1 and AM145NN4DBH1 indoor units with 25 m of piping. The elapsed times were measured when the room temperate reached 25 °C. ² 15 % energy consumption is reduced with an AM080AXVGGH/EU outdoor unit connected to AM083NN4BHD1 and AM145NN4DBH1 indoor units with 25 m of piping, using the cooling operation in Auto mode for 4 hours with an external temperature of 30 °C and a set temperature of 22 °C. Results may vary depending on the actual installation and usage conditions, such as the piping length, elevation and external temperature.

Results may vary depending on the actual installation and usage conditions, such as the piping length, elevation and external temperature.
*** Based on internal testing. Heating time at -10° over a period of 6 hours: Samsung DVM S2 (AM240AXVAGH/EU) = 180 minutes vs. conventional outdoor unit = 110 minutes. Results may vary depending on environmental factors and individual use.
Perfectly compatible with WindFree™ indoor units
WindFree™ Cooling and Active Frequency Drive 10Hz
Enjoy continuous comfort and avoid wasting energy. The DVM S2 range is compatible with our WindFree™ products* that feature our unique WindFree™ technology to cool gently and quietly by dispersing fresh air through thousands of micro-holes to avoid any unpleasant cold drafts**. Active Frequency Drive 10Hz technology enables the compressor to precisely control a small amount of refrigerant. So it maintains a more consistent temperature.
* DVM S2 is compatible with the WindFree™ 4-Way and 1-Way Cassette and the WindFree™ Deluxe.
** ASHRAE (American Society of Heating, Refrigerating, and Air-Conditioning Engineers) defines “Still Air” as air currents at speeds below 0.15m/s which lacks the presence of cold drafts.
Uses less refrigerant due to slimmer liquid line
Slimmer Liquid Pipe
Save installation cost with efficient piping. The DVM S2 uses 28% less refrigerant* as it can use a slimmer liquid pipe**. As a result, it reduces installation and maintenance costs and improves design flexibility. In addition, by using less refrigerant it is more environmentally friendly, as it reduces CO₂ emissions.
* When a slimmer pipe, instead of a normal pipe, is used for the Main Liquid Pipe on the same capacity of air conditioning system, the amount of refrigerant to be charged can be reduced by 28% on average.
** Optional. A slimmer pipe can be used for the Main Liquid Pipe, between an outdoor unit and the first branch of indoor units. The diameter of the slimmer pipe will vary depending on the diameter of the pipe that is normally used. Not available on the 22.4kW and 28kW models. It may not be available in certain installation conditions, and is not compatible with the AI functions of outdoor units. Please contact Samsung’s technical professionals regarding its availability and for more detailed information.
Reduces the disturbance of fan noise
Multi-serration Fan & Diffuser Type Discharge Plenum
Reduce disturbance caused by air turbulence. A Multi-serration Fan* minimises the turbulence of the air vortex, which reduces the air resistance. The discharge plenum’s edgeless, curved design also allows the fan to gently diffuse air without creating a vortex**.
* Only available on certain models that have one fan.
** Based on internal testing and simulation using a fluid dynamics software, Ansys CFX. Results may vary depending on the actual usage conditions.
Lasting protection, optimal performance
Safeguard the Heat Exchanger from damaging corrosion. The Durafin™ Ultra has an anti-corrosive layer and a hydrophilic layer that protects the Heat Exchanger from rust. Its superb corrosion-resistance was proven in a Salt Spray Test (SST)*.
* Based on testing by a third party lab in accordance with ASTM B117, an official test method. For more details, please contact Samsung’s technical professionals.
** Based on testing by a third party lab, applying the actual pressure of refrigerant for 1 minute, after a Salt Spray Test (SST) of over 2,280 hours.
Anti-rust Protection extends lifespan
Galvanized Iron Steel Plate (GI)
Inhibit the formation of rust on the cabinet. It is made of Galvanized Iron Steel Plate (GI) with a PE powder coating that is up to 100µm thick, which improves corrosion-resistance by 43%*. It protects it from rusting, so it can endure harsh conditions.
* Based on internal testing using corrosion chambers, Q-FOG and CCT-1100. The Complex Cycle Test (CCT) includes cycles of spray (for 2 hours at 35°C), dry (for 4 hours at 60°C with 30% Relative Humidity) and damp (for 2 hours at 50°C with 95% Relative Humidity) conditions. As a result, the Galvanized Iron Steel Plate (GI) formed red rust after 240 hours, which is 43% slower than general Electro-Galvanized Steel Plate (EGI) which forms red rust after 168 hours.
Designed to perform in cold climates
Upgraded Base Design & Base Heater
The DVM S2 ensures that you always feel comfortably warm. It delivers reliable heating in extremely cold weather. Its upgraded base design helps drain condensed water quickly so it cannot freeze, and a base heater* melts any ice that forms inside.
* Optional. Available in the second half of 2021. Varies based on the base size of an outdoor unit.
Easy troubleshooting with one touch
On-device Inverter Checker™
Save time identifying system issues and the cost of specialist diagnostic tools. An On-device Inverter Checker™ features a one-touch button that enables you to quickly check for device errors. It is easy to access without removing the entire front cover.
