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.

Table 1. Example of System Peak loads
f
Zone Peak Loads (
): To satisfy the demand for each room any time
- Sum of Zone peak Loads = 65.4kW (11.0 + 10.6 + 10.8 + 10.8 + 11.4 + 10.8)
f Block load ( ).

• When a system combination ratio is over 130%, 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.”
