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

The DVM Chiller is an air to water heat pump

Chill water temperature range: 41°F to 77°F Chill water temp down to 14°F with antifreeze

Hot water temperature range: 77°F to 131°F

Chiller ambient temperature operating range: Cooling: 5°F to 118°F Heating: -13°F to 109°F

10 ton and 15 ton nominal capacity models 208/230vac 3Ø and 460vac 3Ø models Modular combinations from 20 to 240 nominal tons Up to 16 units can be combined in one control group

Optional DMS 2.5 or Touch Central Controllers enable control of 3rd party air handlers

One group with up to 16 units can be controlled by a single Module Controller

Example:

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)

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


Module 1 Module 2


Module 1 Module 2

Operates the unit with the highest priority

Starting

When LWT is close to set point, the unit with the last priority stops

Close to set point

Thermo-Off

When first unit reaches its full speed (80~140Hz) and average LWT, another unit that has the following priority will operate.

↑↑

Operating


26


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
