Due to Samsung’s policy of ongoing product development, specifications are subject to change without prior notice. Every effort has been made to insure that the information included in this presentation is as accurate as possible at the time of it’s publication.
This presentation is provided as a guide to help HVAC field technicians understand the proper procedures for installing Samsung DVM Chiller systems. This training module is not intended to replace Samsung service manuals, technical data books, installation/operation manuals or other factory documents.
Only properly trained, HVAC professionals should attempt to install and start up any Samsung heating and air-conditioning system.
High Voltage Caution:Extra care must be taken when working on or around DVM & DVM S equipment due to numerous high voltage components. Whether installing or servicing DVM equipment in the field or while attending Samsung HVAC training classes which include powered simulators and equipment, be aware of the potential dangers of high voltage USE CAUTION
This presentation may only be used with authorization by Samsung HVAC. Unauthorized use, duplication or alteration of this presentation is prohibited.

DVM Chiller Operation Control Patterns Selectable chiller group operation control patterns
Standard Control – Applications with high cooling/heating load factors All modules in the group start simultaneously Individual unit capacity control is based on the water outlet temperature sensor of each unit As individual units reach setpoint temperature, they go into thermo-off Factory default setting
Start OPERATION
All units will start at the same time. Each unit controls capacity based on its water outlet temperature
When units that have reached set temperature will go into Thermo-Off (idle)

DVM Chiller Operation Control Patterns Selectable chiller group operation control patterns
Rotation Control – Applications with lower loads at system startup and with small load fluctuations Chiller’s water outlet temperature is controlled based on the average temperature of all units in the module The module with the highest priority starts first. When the module reaches full load, the next module with the next priority starts When the module with the lowest priority operates at minimum capacity and the water outlet temperature approaches set temperature,
compressors stop Setting is enabled during commissioning

DVM Chiller Operation Control Patterns Selectable chiller group operation control patterns
Efficiency Control – Applications where the controlled area has a low load System capacity control uses an average leaving water temperature of all operating units in a module Load response time is prioritized as system capacity is increased Efficiency Control maintains compressor operating frequencies in the mid range frequencies (50 – 80Hz) Setting is enabled during commissioning
Start operating a unit with the highest priority.
Starting
50 ~ 80Hz
When the RPM of first unit reaches the most efficient level (60 ~ 80Hz),It starts operating second unit.
50 ~ 80Hz
↑↑
It turns on the next unit in order of priority as cooling load increase. The max. rpm is still limited below 50 ~ 80Hz.
Operating
↑↑
As the cooing load changes, the RPM of operating units will increase/decrease at the same time.
↑↑↑↑↑↑↑↑
When the RPM of operating units are below 50Hz, it will turn off one of the units with the lowest priority.

DVM Chiller Operation Control Patterns
Water Law Control – Applications where efficiency is increased by resetting the leaving water temperature based on outside ambient temperature or room temperature When chiller is configured for standard water temperature range (default) the operating water
temperature range in cooling will not drop below 41°F When chiller leaving water temperature is controlled by room temperature, a field supplied TP100
external sensor must be used or a signal from a BMS control
