Vertiv SmartRow DCR, Инструкция по установке и эксплуатации

Страница: 9 / 102

2 INTRODUCTION
The SmartRow DCR is an integrated component of the SmartRow
™
offering from Vertiv™. The system
includes a closed-loop, integrated cooling system and fire suppression. Assembly is a matter of
connecting the plenums and cabinets, then making electrical and piping connections.
The SmartRow DCR is available in three basic cooling configurations:
• 20-kW (N) Configuration—3- to 6-rack system capable of removing up to 20 kW of heat (single
Liebert PDX/PCW).
• 20-kW (N+1) Configuration—3- to 6-rack system capable of removing up to 20 kW of heat
(redundant Liebert PDX/PCW).
• 36-kW (N) Configuration—5- to 10-rack system capable of removing up to 36 kW of heat (dual
Liebert PDX/PCWs).
Each configuration has different requirements and recommendations for setup and operation. Those
requirements are integral to effective operation of a SmartRow DCR.
The SmartRow DCR must be installed in an indoor, climate-controlled environment. The unit will not
protect electronic equipment if it is installed in an environment subject to extreme temperatures or
humidity.
This manual is to be used in conjunction with existing Vertiv™ product manuals for each component and
site-specific documentation and drawings. User and installation manuals ship with the equipment and are
also available at http://www.VertivCo.com/en-us/support/.
2.1 Operational Overview
The SmartRow DCR is an enclosed system to house and cool electronic equipment. The DCR racks house
the critical IT equipment, optional Rack PDUs and optional rack-mounted UPS units.
Cooling air is supplied by an integral Liebert PDX/PCW and conveyed to the racks with bottom plenums.
Heated exhaust air from the racks returns to the Liebert PDX/PCW through the top plenums. An
emergency fan system is included to exhaust air in the event of excessive internal temperature or a
primary cooling failure.
The DCR Control Panel and Fire Suppression System module contains the fire detection and suppression
system, fire strobe light and audible horn, the power/fire control interface, fire-suppression-system abort
and manual-release switches, emergency fan-reset controls, and the load-distribution center. The
fire-detection system uses a smoke detector to monitor the air in the SmartRow DCR for evidence of
combustion. If the smoke detector mounted in the return air plenum senses combustion products, the
system control activates audible and visual alarms and releases a fire-suppression agent (see Figure 7.1
on page 61). The load-distribution center distributes power to powered loads inside the SmartRow DCR.
2.2 DCR Control Panel and Fire-suppression System Commissioning and Training
A local qualified service representative will commission and arm the DCR Control Panel and Fire
Suppression System after the SmartRow DCR is fully installed and operational. The representative will
conduct training on the system during the same visit. The commissioning, arming and training cannot be
performed before all items in
Cooling and Power Component Installation Checklist on page 67, and Fire
Suppression System Installation Checklist on page 68, have been completed.
