Discover the entire line of Samsung’s innovative VRF systems. Samsung DVM S – smart products for smarter businesses.

What is VRF?

Glad you asked.

Variable Refrigerant Flow (VRF) systems consist of outdoor units connected to multiple indoor units via refrigerant piping to provide cooling and heating to individual zones. The outdoor units can modulate capacity based on the requirements of the individual zones, thus saving energy by not always running at 100% capacity and improving occupant comfort by maintaining the temperature as needed in each individual zone.

With design flexibility, premium comfort, and superior performance, Samsung DVM S VRF air conditioning systems offer just the right solution for any application.

Design Flexibility

Compact Equipment

Small outdoor unit footprints allow for installation in applications where space is limited, such as on crowded rooftops, or in tight mechanical closets. DVM S systems feature a design diversity ratio of 50 – 200%**. Diversity ratios above 100% mean connecting more indoor unit capacity than outdoor capacity taking advantage of shifting building loads

Wide Variety of Indoor Unit Options

Our indoor units offer superior performance, flexible installation, and ease of operation. These units employ innovative technologies, like our Wind-Free™* cooling technology, to optimize comfort in any environment. With over 10 types of indoor units, ranging from 5,000 to 96,000 Btu/h, there are solutions for almost any application.

Extended Piping Length

DVM S systems offer installation options with extended piping lengths up to 722 ft, vertical separation up to 361 ft between the outdoor unit and furthest indoor unit, and 164 ft between the highest and lowest indoor units.

Control Integration Options

A number of control options are available to fit a variety of project needs, from simple local controllers to full central control options. This grants the capability to integrate into any Building Management System (BMS) through BACnet, LonWorks, or ModBus.

Removable EEPROM Chip

DVM S systems are equipped with a removable EEPROM chip at the main PCB to store data. This allows for the replacement of the control PCB without losing startup information, system settings, and other field-programmed data. In addition, this allows for ease of startup, commissioning, and product registration.


Ultimate Zoning Solution

Samsung DVM S systems allow for precise temperature control in multiple zones, providing comfort to a wide range of occupants. Heat Recovery systems add the capability to heat and cool separate zones simultaneously making it a superior choice.

Quiet Operation

Samsung systems are meticulously designed with the user in mind, and minimizing sound levels is a key design aspect our engineers focus on.


Flash Injection Technology

DVM S systems† uniquely feature flash injection compressor technology that increases heating performance with a two-phase refrigerant that is activated during heating mode in low ambient conditions.


Samsung DVM S systems feature several smart technologies that are designed to deliver comfort and efficiency. These
systems provide the perfect solution for businesses looking to optimize power and energy costs.

Intelligent Defrost Technology

DVM S systems do not only consider time and temperature like most VRF systems but temperature and outdoor heat exchanger air resistance to determine when to start defrosts operation‡.

Low Ambient Cooling

Compatible with both DVM S Heat Pump and Heat Recovery models, our Low Ambient Cooling Hood provides 100% cooling capacity down to -13°F (-25°C). Advanced integrated logic allows for louver positioning based on outdoor unit high pressure, outdoor ambient temperature, compressor compression ratio, and operating mode.

Low Ambient Heating

With the ability to produce high heating capacity at -13°F (-25°C), our DVM S systems are a smart solution for commercial buildings in areas that experience low outdoor ambient temperature. Some models may produce up to 100% heating capacity at -13°F (-25°C) outdoor ambient temperature.

Individual Control

There are many different ways to control a Samsung system. For applications where a wireless controller is not acceptable (i.e. public facilities), two wired controllers, Touchscreen and Premium, are available to purchase as an option. Based on the desired level of control and user interface preference, Samsung offers a variety of wired controllers suitable for any application. Additionally, a Thermostat Adapter can be applied to control up to two indoor units on the same system simultaneously with a 24VAC thermostat. Visit to learn more.
