System Description 1 1.0 S YSTEM D ESCRIPTION The Liebert XD™ family of cooling units delivers efficient, sensible cooling to high-heat environ- ments. Liebert XD systems are desi gned to cool computer racks and hot zones in a data center or com- puter room without taking up expensiv e floor space for co olin g components.
System Description 2 1.1 European Union Fluorinated Greenhouse Gas Requirement s Stationary air conditioning, refrigerat ion, heat pu mp equipments and stationa ry fire protection sys- tems in the Eur.
System Description 3 1.3 Liebert XDO—Over head Cooling Module The Liebert XDO ceiling-mounted cooling module draw s in hot air rising from densely populated cab- inets, passes it over the Liebert X DO’s coils and exha usts cooled air downward into the cold aisle.
System Description 4 1.4 Liebert XDV—V ertical, Ab ove-Cabinet Cooling Module The Liebert XDV is installed o n 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 pi pes.
System Description 5 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-c old aisle arrang ement. The Li ebert XDH ha s dual refrigerat ion circuits and is availabl e in a half-rack-width un it.
System Description 6 1.6 Liebert XDCF The Liebert XDCF is a self-contained module design ed to cool Ege nera’s BladeFrame EX cabinets and equipment without exhausting heat into the room. T wo modules (top and bottom) may be mounted on the rear of a BladeFrame cabinet.
System Description 7 1.7 Liebert XDA—Air Flow Enhancer The Liebert XDA is a fan unit that boosts the airf low through densel y populated enclosures, removing hot spots from within the racks. One or two units ca n be mounted on the rear of most rack enclosure s.
System Description 8 1.8 Liebert XDP—Pumping Unit The Liebert XDP isolates the buildi ng’s chilled water circuit from th e pumped refrigerant circuit.
System Description 9 1.9 Liebert XDC—Refrigerant Chiller The Liebert XDC is an indoor chi ller that connects directly to the Liebert XD cooling modules and pro- vides refrigerant circulati on and control.
System Description 10 1.10 Liebert XD Piping Liebert XD Piping is prefabricated di stribution piping that is installed in a nticipation of a growing sys- tem. Liebert XD cooling modules are a dded as required and are quickly made operational with f lexible connection piping with threaded couplings.
Starting a New Equipment Cooling Project 11 2.0 S TA R T I N G A N EW E QUIPMENT C OOLING P ROJECT 2.1 Determining Cooling Equipment Needs 1. Is adequate space av ailable for a Lieb ert XD installation? 2. Is the hot aisle/cold aisle approach being util ized for this room design or can it be utilized in this room design? 3.
Starting a New Equipment Cooling Project 12 2.2 Implementing a Hot-Aisle/Cold Aisle Design A best practice is to use rows of equipment racks in an alternating arrangemen t of cold aisles and hot aisles.
Designing a Li ebert XD Solution 13 3.0 D ESIGNING A L IEBERT XD S OLUTION Liebert XD systems are intended for use with p recis ion air conditioni ng equipment, such as the Lie- bert Delux e System/3 and Liebert D S. The precision ai r conditioning equi pment is required to control the room’s humid ity and to filter the ai r.
Designing a Li ebert XD Solution 14 3.3 Selecting Liebert XD Cooling Modules The next step is to select the Li ebert XD coo ling modules to be con figured into the solution. Liebert XD modules that use pumped refrigerant can be co nnected to the same Liebert XDP/Liebert XDC pip- ing circuit.
Designing a Li ebert XD Solution 15 3.6 Liebert XDO Placement 3.6.1 Determining S p acing of Liebert XDOs in an Aisle Liebert XDO units should be placed in rows directly above the cold aisles of a room for optimum cool- ing. Each Liebert XDO serves an area equal in width to the cold aisle spacing, typically 12 to 16 feet (3.
Designing a Li ebert XD Solution 16 3.6.2 Determining V ertical Placeme nt of Liebert XDOs Above the Cold Aisle In the maximum density configuration, Emerson recommends pl acing the Liebert XDOs between 18 and 24 inch es (457-609mm) above the equipment cabinets.
Designing a Li ebert XD Solution 17 3.7 Liebert XDV Unit Placement Liebert XDV units sh ould be placed o n top of the ca binets that g enerate the greatest amount of heat. If heat loads are dispersed evenly throughout th e room, the Lieber t XDV mo dules may be spread out accordingly.
Designing a Li ebert XD Solution 18 3.8 Liebert XDCF Placement The Liebert XDCF is a self-contained module design ed to cool Ege nera’s BladeFrame EX cabinets and equipment. Liebert XDCF modules a ttach to the rear of the Egenera BladeFrame EX ca binet, b eside the power modules (see Figure 17 ).
Designing a Li ebert XD Solution 19 3.9 Liebert XDH Placement The free-standi ng Liebert X DH cooling unit is best p laced amon g the equipm ent cabinets in a hot aisle-cold aisle arrangement (see Figure 18 ).

Designing a Li ebert XD Solution 22 3.12 Liebert XD Refrigerant The refrigerant used in the Liebert X D system is HFC-134a ( 1,1,1,2-tetrafluoroetha ne), made by a number of manufacturers. The amo unt of refrigerant used by the Liebert XD system may be signi fi- cantly higher than in typical DX coo ling systems.
Designing a Li ebert XD Solution 23 Figure 23 Piping for Liebert XDP/Liebert XDC used with Liebe rt XD cooling units The assembly and connection means used for piping in the Liebert XD system are similar to that of conventional refrigeration systems. All pi ping should be in stalled with high te mperature brazed joints.
Designing a Li ebert XD Solution 24 Figure 24 Hydraulic diagram 3.14 Liebert XD Piping Slope The main supply and return lines to and from the XDP/XDC must be sloped downward toward the XDP/XDC at a rate of 1-2" per 20 feet (25-51mm per 6m) of pipe run.
