    YSTEM ESCRIPTION The Liebert XD™ family of cooling units delivers efficient, sensible cooling to high-heat environ- ments. Liebert XD systems are designed to cool computer racks and hot zones in a data center or com- puter room without taking up expensive floor space for cooling components. The Liebert XD family includes: •...
  • Page 8: European Union Fluorinated Greenhouse Gas Requirements

    European Union Fluorinated Greenhouse Gas Requirements Stationary air conditioning, refrigeration, heat pump equipments and stationary fire protection sys- tems in the European Community market and operating with fluorinated greenhouse gases (f-gas), such as R407C, R134a, R410A, must comply with the F-Gas Regulation: (EC) No. 842/2006 (F-gas). The regulation prohibits, among other actions, venting fluorinated greenhouse gases to the atmo- sphere.
  • Page 9: Liebert Xdo-Overhead Cooling Module

    Liebert XDO—Overhead Cooling Module The Liebert XDO ceiling-mounted cooling module draws in hot air rising from densely populated cab- inets, passes it over the Liebert XDO’s coils and exhausts cooled air downward into the cold aisle. The unit is available with optional, flexible metal pipes with quick-connect couplings at each end for easy connection to the refrigerant distribution pipes.
  • Page 10: Liebert Xdv-Vertical, Above-Cabinet Cooling Module

    Liebert XDV—Vertical, Above-Cabinet Cooling Module The Liebert XDV is installed on top of or above a rack enclosure. It is available with optional flexible metal pipes with automatic shutoff with quick-connect couplings at the ends for easy connection to the refrigerant distribution pipes. The Liebert XDV may be set up in either of two ways: •...
  • Page 11: Liebert Xdh-Horizontal Cooling Module

    Liebert XDH—Horizontal Cooling Module The Liebert XDH cooling module is designed to be placed within a row of server enclosures in a hot aisle-cold aisle arrangement. The Liebert XDH has dual refrigeration circuits and is available in a half-rack-width unit. The Liebert XDH is intended for use with a Liebert XD pumped refrigerant cool- ing system, supplied by either a Liebert XDP or Liebert XDC.
  • Page 12: Liebert Xdcf

    Liebert XDCF The Liebert XDCF is a self-contained module designed to cool Egenera’s BladeFrame EX cabinets and equipment without exhausting heat into the room. Two modules (top and bottom) may be mounted on the rear of a BladeFrame cabinet. CF modules consist of a sheet-metal frame, coil and filter dryer. It has no moving parts and needs no electricity.
  • Page 13: Liebert Xda-Air Flow Enhancer

    Liebert XDA—Air Flow Enhancer The Liebert XDA is a fan unit that boosts the airflow through densely populated enclosures, removing hot spots from within the racks. One or two units can be mounted on the rear of most rack enclosures. Figure 9 Liebert XDA—air flow enhancer—on Liebert Foundation enclosure System Description...
  • Page 14: Liebert Xdp-Pumping Unit

    Liebert XDP—Pumping Unit The Liebert XDP isolates the building’s chilled water circuit from the pumped refrigerant circuit. The Liebert XDP circulates refrigerant to Liebert XDCF, Liebert XDH, Liebert XDO or Liebert XDV mod- ules while preventing condensation by maintaining the refrigerant’s temperature above the dew point.
  • Page 15: Liebert Xdc-Refrigerant Chiller

    Liebert XDC—Refrigerant Chiller The Liebert XDC is an indoor chiller that connects directly to the Liebert XD cooling modules and pro- vides refrigerant circulation and control. The Liebert XDC keeps the refrigerant temperature above the dew point and eliminates the need for a separate pumping unit in the direct system configuration. The Liebert XDC employs two sets (for redundancy) of remote sensors to determine the temperature and humidity in the air and instantly adjusts refrigerant supply temperature to compensate for changing conditions.

  • Page 17: Starting A New Equipment Cooling Project

    TARTING A Determining Cooling Equipment Needs Is adequate space available for a Liebert XD installation? Is the hot aisle/cold aisle approach being utilized for this room design or can it be utilized in this room design? Is redundant cooling equipment required? Are there access considerations for all components (possible rigging problems) What heat load growth is anticipated over the next few years? How are the cabinets going to be populated (density of heat generation)?
  • Page 18: Implementing A Hot-Aisle/Cold Aisle Design

    Implementing a Hot-Aisle/Cold Aisle Design A best practice is to use rows of equipment racks in an alternating arrangement of cold aisles and hot aisles. This is best accomplished when the layout of the file-server farm area is first being planned, and it is exceedingly more difficult to accomplish when the computer room is already populated with operating hardware.
  • Page 19: Designing A Liebert Lxd Solution

    ESIGNING A IEBERT Liebert XD systems are intended for use with precision air conditioning equipment, such as the Lie- bert Deluxe System/3 and Liebert DS. The precision air conditioning equipment is required to control the room’s humidity and to filter the air. The Liebert XD systems provide efficient, highly effective heat removal (sensible cooling only), and provide no dehumidification.
  • Page 20: Selecting Liebert Xd Cooling Modules

    Selecting Liebert XD Cooling Modules The next step is to select the Liebert XD cooling modules to be configured into the solution. Liebert XD modules that use pumped refrigerant can be connected to the same Liebert XDP/Liebert XDC pip- ing circuit. This includes the Liebert XDCF, Liebert XDH, Liebert XDO and Liebert XDV. Generally, the Liebert XDO is selected for use in new installations or renovations where the unit can be installed on the ceiling or in the overhead space.
  • Page 21: Liebert Xdo Placement

    (1.8m), overall performance of the system may be negatively affected and gaps in cooling may occur. Emerson recommends installing one Liebert XDO at the end of each aisle being cooled and to space the remainder between these end units in pairs as shown in Figure 15. This layout will block the incursion of hot air around the side of the end cabinets.
  • Page 22: Determining Vertical Placement Of Liebert Xdos Above The Cold Aisle

    3.6.2 Determining Vertical Placement of Liebert XDOs Above the Cold Aisle In the maximum density configuration, Emerson recommends placing the Liebert XDOs between 18 and 24 inches (457-609mm) above the equipment cabinets. In some cases where the required density is less, the front-to-rear spacing of Liebert XDOs in a row will be increased. To ensure coverage of the wider spaces between the Liebert XDO units, the vertical distance between the cabinets and the Lie- bert XDOs should be increased.
  • Page 23: Liebert Xdv Unit Placement

    Liebert XDV Unit Placement Liebert XDV units should be placed on top of the cabinets that generate the greatest amount of heat. If heat loads are dispersed evenly throughout the room, the Liebert XDV modules may be spread out accordingly. The Liebert XDV must be placed toward the front of the equipment cabinet, so that its front bottom edge is flush with the front top edge of the cabinet.
  • Page 24: Liebert Xdcf Placement

    Liebert XDCF Placement The Liebert XDCF is a self-contained module designed to cool Egenera’s BladeFrame EX cabinets and equipment. Liebert XDCF modules attach to the rear of the Egenera BladeFrame EX cabinet, beside the power modules (see Figure 17). No cutting or drilling is required to attach the modules; all mounting holes, slots and pins required are fabricated at the factory.
  • Page 25: Liebert Xdh Placement

    Liebert XDH Placement The free-standing Liebert XDH cooling unit is best placed among the equipment cabinets in a hot aisle-cold aisle arrangement (see Figure 18). The Liebert XDH draws in air from the hot aisle, cools it and discharges the cooled air into the cold aisle where it is drawn into the equipment cabinets. Reg- ular spacing aids in optimizing cooling.

The amount of refrigerant used by the Liebert XD system may be signifi- cantly higher than in typical DX cooling systems. CAUTION Risk of improper oil use.
