Features & Benefits
Rebuilt on all new innovations
Rethink your approach to air conditioning with the Samsung DVM S2.
It delivers outstanding comfort and energy efficiency, even in extreme climates.
Its intelligent features make installation and maintenance easier and more cost-effective.
Perfectly compatible with WindFree™
Active Frequency Drive 10Hz
Enjoy continuous comfort and avoid wasting energy. Active Frequency Drive 10Hz technology enables the
compressor to precisely control a small amount of refrigerant. So it maintains a more consistent
temperature and is compatible with Samsung’s WindFree™ Cooling.

Features & Benefits
Enabling a new era of consistent comfort
Advanced Flash Injection Compressor
Enter a new era of non-stop comfort and efficiency. The Advanced Flash Injection Compressor
provides the world’s largest capacity*. It combines Flash Injection technology with a strengthened
Triple Profile Scroll and efficient Optimal Discharge Superheat (DSH) Control technology.
* Samsung circulates 14,400cc/sec refrigerant (= 90cc (displacement volume) x 160rps (revolutions per second)), while Company A circulates 12,480cc/sec (= 96cc x 130rps), Company B circulates
14,080cc/sec (= 88cc x 160rps) and Company C circulates 12,320cc/sec (= 88cc x 140rps).
More powerful performance, less space
34HP Super Capacity with a Compact
Design
Enjoy an exceptionally powerful
performance and use less space. It’s the
first outdoor unit to offer super capacities
of 32HP and 34HP in a single unit. Their
compact design saves up to 18% space*
and helps reduce the cost and effort of
installation.
* Based on internal testing compared to both Samsung conventional outdoor units and those of other brands.

NOTE
• Ma ke sure to use an indoor unit that is compatible with DVM S.
•Indoor units can be connected within the range indicated in following table.
•If the total capacity of the connected indoor units exceeds the indicated maximum capacity, cooling and heating
capacity of the indoor unit may decrease.
•Total capacit
y of the connected indoor units can be allowed from 50% to 130% of the total outdoor unit capacity.
0.5 × Σ( Outdoor unit capacity) ≤ Total capacity of the connected indoor units ≤ 1.3 × Σ( Outdoor unit capacity)
※You can connect maximum 64 indoor units to the outdoor unit. Maximum quantity of connectable indoor unit is set to 64
since outdoor unit only support up to 64 communication address. Indoor unit address can be
assigned from 0~63. If the indoor unit address was assigned from 64~79, E201 errorwill occur.
※Maximum 32 Wall-mount type indoor units with EEV (AM∗∗∗∗NQDEH∗∗∗, AM∗∗∗JNVDKH∗∗∗) can be connected.

1.Design Procedure & Combination Ratio
Definition of Combination Ratio, CR
CR = Sum of Nominal Cooling Capacity of Indoor units *100%
Nominal Cooling Capacity of Outdoor unit
Constraints of Allowable Combination Ratio
DVM S systems are normally designed to utilize a CR 50% to 130% to ensure effective load balancing between indoor units
and outdoor unit. As buildings have become more insulated, and usage and occupancy of buildings are highly variable,
more buildings can realize a higher load balancing between IDUs and ODU, thus higher CR (>130%) is often required. If a
system design exceeds 130%, risks associated to increased indoor sound level and reduced comfort levels should be
considered. Therefore, when it is necessary to design a combination ratio exceeding 130%, the following conditions must
be complied with: -
Design & Selection Procedure
Determine DVM Design Condition
• Design temperature
• Calculate cooling and heating loads (Zone peak loads/System Peak load)
• Power supply, piping length and level difference
Select indoor unit for each zone
Max capacity at design condition should be greater than Zone Peak Load
Select outdoor unit
(Max capacity at design condition should be greater than System Peak Load)
Go to the next step to
complete design
Size up outdoor unit or change indoor unit type or capacity
Decide Minimum Operation Ratio in heating mode
Total nos. of indoor units exceed limit?

1.Design Procedure & Combination Ratio
Satisfying cooling & heating comfort
The Maximum Capacity of outdoor unit at design condition calculated from Samsung capacity data table or design
tool (DVM Pro) should always be the same or greater than System Peak Load (Block Load) defined in table 1.

• When a system combination ratio is over130%, a max system capacity is the same as the published
capacity in TDB capacity table at the combination ratio of 130%
NOTE
Cooling Operation Only
When only cooling operation is used, CR is allowed up to 180% if the Max Capacity of outdoor unit is greater than
System Peak Load (Block load) as shown table 2.
Outdoor unit All capacities of H/P & H/R model
Indoor unit All indoor unit types
Operation Condition Cooling mode only
Allowable CR 180%
Table 2. Allowable CR in only cooling operation
• Table 2 shows a standard for allowable CR of cooling only model. Samsung Electronics is not
responsible for any problem caused by using a heating mode at the site with a system designed by
table 2. If heating operation is required, extended CR design must follow section “Allowable CR limit to
avoid abnormal sound level risks in heating operation.”
