Piping

3.3Liebert XDP Interconnection with Liebert XD Cooling Modules

All piping must be ASTM (American Society for Testing and Materials) Type ACR copper pipe.

The Liebert XDP may be connected to Liebert XD cooling modules with either Liebert’s XD prefabricated piping assembly or with rigid, off-the-shelf piping. In either setup, piping for the Liebert XD system is arranged in a manner similar to piping for a chilled water system. Liebert XD cooling modules are connected in parallel between main return and supply pipes going to and from the Liebert XDP/Liebert XDC. Figure 19 represents a typical configuration. For piping details, refer to Liebert’s XD System Design Manual, SL-16655, available at Liebert’s Web site: www.liebert.com. The guidelines provided for pipe size must be strictly followed. Failure to size the main lines and connection lines adequately may result in reduced cooling capacity. The critical aspects of pipe sizing are related to refrigerant volume and pressure drop. Each must be minimized.

3.4Piping Installation Methods

The assembly and connection means used for piping in the Liebert XD system are similar to those used for conventional refrigeration systems. All piping should be installed with high-temperature brazed joints. Soft soldering is not recommended.

During brazing, the lines must be filled with flowing dry nitrogen to prevent excessive oxidation and scale formation inside the piping. Prevailing good refrigeration practices must be employed for piping supports, leak testing, dehydration and charging. Failure to use good system practices may result in damage to the system. Refer to the ASHRAE refrigeration handbook for general good-practice refrigeration piping.

Insulate all piping lines to prevent condensation in applications where the dew point approaches the R-134a refrigerant temperature.

Emerson recommends venting the pressure relief valve for the R-134a outside the conditioned space where it is open to the atmosphere. The R-134a side relief valve is inside the Liebert XDP unit at the top of the receiver.
