Product Description

1.0PRODUCT DESCRIPTION

1.1General Product Information

1.1.1Product/System Description

Liebert’s XDP refrigerant distribution unit is an interface between the building chilled water system and the cooling modules in the Liebert XD system. It is designed to circulate and control refrigerant to the cooling modules that are in the room with heat-producing equipment. The Liebert XDP is rated for 160kW (546,000BTU/H) of cooling.

The Liebert XDP consists of a cabinet that includes a heat exchanger, circulating pump(s), control valve, receiver, controls, valves and piping.

The Liebert XDP monitors room conditions and prevents coil condensation by maintaining the refrigerant being pumped to the cooling modules at a temperature above the room’s dew point.

All functions, such as switching pumps (if applicable), controlling refrigerant temperature, etc., are automatic.

2.4Remote Sensor Installation—Proper Placement

Placement of the two remote temperature/humidity sensors is critical to effective cooling of the conditioned space.

The remote sensors must be installed in areas where conditions are representative of the space conditioned by the Liebert XDP. Emerson recommends installing the sensors in different areas near the cooling modules served by the Liebert XDP. If the return air side of the primary air mover, such as a Liebert DS, represents the conditions where the Liebert XD cooling modules are located, one sensor could be placed there. Emerson suggests placing the other sensor on the wall opposite the heat load area (see Figure 18 for guidance).

Do not install the sensors where ambient air might cause false readings, for example, near unsealed doors or windows, or areas with stagnant air.

1.Unpack the two remote temperature/humidity sensors and cables.

One sensor is labeled Sensor A and the other Sensor B. The sensor cables are interchangeable; each bears labels indicating Sensor End and Unit End.

2.Connect the Sensor End of one of the supplied sensor cables to P66 on Sensor A (see Figure 14).

3.Connect the Unit End of the sensor cable to P67 on the Liebert iCOM input/output board inside the Liebert XDP. Secure the ring terminal on the cable shield to the electric box adjacent to P67 (see Figure 14).

4.Connect the Sensor End of the second sensor cable to P66 on Sensor B (see Figure 14).

5.Connect the Unit End of the cable to P67 on the Liebert iCOM display (see Figure 14). Secure the ring terminal on the cable shield to the grounding screw adjacent to P67.

Piping

3.0PIPING

3.1European Union Fluorinated Greenhouse Gas Requirements

Stationary air conditioning, refrigeration, heat pump equipment 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.

The F-Gas Regulation requires operators to use all measures that are technically feasible and do not entail disproportionate cost to prevent leakage of these gases, to test for leakage regularly and to recover f-gas before disposing of equipment, as well as during service and maintenance.

Refer to the full regulation for additional details.

3.2Connection Sizes

The copper pipe connections on the Liebert XDP are:

Building Chilled Water Supply	2-5/8" OD
Building Chilled Water Return	2-5/8" OD
Refrigerant Supply	1-1/8" OD
Refrigerant Return	2-1/8" OD

3.2.1Recommended Pipe Size

Connect the main pipes between the Liebert XDP and the Liebert XD cooling modules according to site specific documentation and the configuration guide for the Liebert XD system.

Elbows and restrictions must be minimized to get good fluid flow.
