System Description 1.0 SYSTEM DESCRIPTION The Liebert XD™ family of cooling units delivers efficient, sensible cooling to high-heat environments. Liebert XD systems are designed to cool computer racks and hot zones in a data center or computer room without taking up expensive floor space for cooling components.
System Description 1.1 European Union Fluorinated Greenhouse Gas Requirements Stationary air conditioning, refrigeration, heat pump equipments and stationary fire protection systems 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 atmosphere.
System Description 1.3 Liebert XDO—Overhead Cooling Module The Liebert XDO ceiling-mounted cooling module draws in hot air rising from densely populated cabinets, 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.
System Description 1.4 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: • The Liebert XDV can take hot air directly from an equipment enclosure, cool the air and discharge it downward into the cold aisle.
System Description 1.5 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 cooling system, supplied by either a Liebert XDP or Liebert XDC.
System Description 1.6 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.
System Description 1.7 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.
System Description 1.8 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 modules while preventing condensation by maintaining the refrigerant’s temperature above the dew point.
System Description 1.9 Liebert XDC—Refrigerant Chiller The Liebert XDC is an indoor chiller that connects directly to the Liebert XD cooling modules and provides 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.
System Description 1.10 Liebert XD Piping Liebert XD Piping is prefabricated distribution piping that is installed in anticipation of a growing system. Liebert XD cooling modules are added as required and are quickly made operational with flexible connection piping with threaded couplings. This unique system allows the room cooling capacity to increase to more than 30kW per rack with no additional disruptive piping installation.
Starting a New Equipment Cooling Project 2.0 STARTING A NEW EQUIPMENT COOLING PROJECT 2.1 Determining Cooling Equipment Needs 1. Is adequate space available for a Liebert XD installation? 2. Is the hot aisle/cold aisle approach being utilized for this room design or can it be utilized in this room design? 3. Is redundant cooling equipment required? 4. Are there access considerations for all components (possible rigging problems) 5.
Starting a New Equipment Cooling Project 2.2 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.
Designing a Liebert XD Solution 3.0 DESIGNING A LIEBERT XD SOLUTION Liebert XD systems are intended for use with precision air conditioning equipment, such as the Liebert 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.
Designing a Liebert XD Solution 3.3 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 piping circuit. This includes the Liebert XDCF, Liebert XDH, Liebert XDO and Liebert XDV.
Designing a Liebert XD Solution 3.6 Liebert XDO Placement 3.6.1 Determining Spacing of Liebert XDOs in an Aisle Liebert XDO units should be placed in rows directly above the cold aisles of a room for optimum cooling. Each Liebert XDO serves an area equal in width to the cold aisle spacing, typically 12 to 16 feet (3.7 to 4.9m). The length of the area served includes any space between Liebert XDO modules in a row.
Designing a Liebert XD Solution 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.
Designing a Liebert XD Solution 3.7 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.
Designing a Liebert XD Solution 3.8 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. The Liebert XDCF does not require electrical connections.
Designing a Liebert XD Solution 3.9 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. Regular spacing aids in optimizing cooling. Liebert XDH units should be placed among the cabinets that generate the greatest amount of heat.

Designing a Liebert XD Solution 3.12 Liebert XD Refrigerant The refrigerant used in the Liebert XD system is HFC-134a (1,1,1,2-tetrafluoroethane), made by a number of manufacturers. The amount of refrigerant used by the Liebert XD system may be significantly higher than in typical DX cooling systems. ! CAUTION Risk of improper oil use. Can cause equipment damage. The Liebert XD pumped R-134a refrigerant circuits do not use refrigerant oil. Do NOT put oil in the R-134a system.

Designing a Liebert XD Solution 3.16 Determining Refrigerant Volume After the preliminary system design is completed, Tables 7, through 15 may be used to determine the amount of refrigerant required. Perform the calculation below for each Liebert XD system being configured. NOTE All lengths in Tables 7, 8, 9 and 10, are actual pipe lengths, not equivalent pipe lengths. 3.16.

Designing a Liebert XD Solution 3.16.2 Calculating Refrigerant Charge—Example Using Tables 7, 8, 9 and 10, calculate the refrigerant charge of the individual sections of your Liebert XD system. Add the calculated charge amounts to determine the amount of R-134a refrigerant required for one system combining a Liebert XDP with Liebert XD cooling modules (Liebert XDCF, Liebert XDH, Liebert XDO and Liebert XDV). The example below combines one Liebert XDP with 20 Liebert XDV8 cooling modules.
