Liebert DS Configuration - UpFlowWhen Data Center Management and Computer Room Air Conditioning (CRAC) Meets Old Man Time

How do you handle Data Center Management when construction demands that you turn off the cooling without melting the servers?

Updating a Liebert CRAC system can be complicated, and the larger the system, the more complex becomes the operation. Shutting down big computer room air conditioning environments demands forethought, long-range planning, and access to a host of well trained HVAC and electrical service professionals.

For example: Greening Columbia University recently upgraded the core chilled water cooling system and electrical power supply line for the University’s existing data center. The project required a full mechanical shutdown of the cooling plant. Existing unused cooling pipe had to be demolished. New and upgraded electrical components had to be installed. Various additional construction processes affected the overall activity. And they were working with the wear and tear that so often affects conditions in a 50-year old facility. Thus along with the upgrades and component replacements, the University took opportunity to press the CRAC service team for extensive preventative maintenance.

Data Center Management – When Reducing the CRAC Becomes Unavoidable

The functionality of your data center is mission critical to daily and yearly business or organizational operations. In the above scenario, Greening Columbia University was dealing with a computer room air conditioning system that typically demanded a 120-ton operating load. Shutting down non-critical services for even one day still left them facing a need to cool nearly 700 servers, merely two-thirds of the center’s normal capacity. Thus for completion of the work, a temporary 50-ton cooling system had to be employed.

This is what mission critical data center management is all about. When reducing the CRAC becomes unavoidable, you need reliable HVAC technicians who have been trained and who continue to train in all aspects of mission-critical precision cooling product installation, services and management. American Cooling and Heating provides full-service commercial HVAC installation, repairs and support for Liebert CRAC precision cooling equipment throughout Chandler AZ, Gilbert AZ, Glendale AZ, Mesa AZ, Peoria AZ, Scottsdale AZ, Tempe AZ, And All Other Phoenix Areas.

Effective CRAC services begin with efficient installation and carry through to reliable system maintenance and services. Rightly configuring your Liebert DS cooling system for optimal performance requires skill, training, and on-the-job know-how. As a world renown leader in manufacture and installation of mission-critical Liebert precision cooling systems and CRAC products, Arizona based American Cooling and Heating can help you get your system up and running quickly and efficiency.

Time Out For Q&A!

For what purpose serves a time delay on an AC unit?

Answer:

When running a single-phase scroll compressor, you may encounter concerns about a pressure-equalization time delay. During off-cycle pressure equalization, scroll compressors spin backwards. Short cycling and energizing a scroll during this time period can cause the unit to continue spinning backwards. Once initiated, this reverse spin will continue until manual ended or the unit trips on internal overloads. Thus may end the life your scroll compressor.

More often than not, a time delay will be linked to anti-short cycling. Short cycling during compressor rush can cause the system to continuously trip a low-pressure safety switch, which in turn can damage the unit. By taking advance of features in a pump down solenoid, some systems isolate refrigerant during off cycling. If the compressor is controlled solely off the LP safety, a faulty LL solenoid can cause pressure to rise in the evaporator during an off cycle. This problem can be present in the recip compressor of an older Liebert Deluxe system.

5 Field Options for Liebert DS Cooling Configurations

1) AIR-COOLED – Liebert DS Cooling Configuration

This process requires piping of field-supplied refrigerant to the condenser. The unit contains a nitrogen holding charge and factory-issued piping is spun closed.

2) GLYCOL-COOLED – Liebert DS Cooling Configuration

Factory charged and confirmed reliable, Glycol-cooled Liebert DS units require field supplied and installed piping from the pump package to the drycooler.

3) GLYCOOL-INTEGRATED FLUID ECONOMIZER – Liebert DS Cooling Configuration

As with the base Glycol-cooled unit, Glycool systems ship factory charged and tested. Piping from the pump package to the drycooler is field supplied and field installed. To complete the installation, cold glycol is circulated through a secondary Liebert Economizer coil that is designed to reduce compressor load when fluid temperatures drop below room temperature.

4) WATER-COOLED – Liebert DS Cooling Configuration

As with the other units, a water-cooled Liebert DS system ships factory charged and factory tested. The piping that runs from the cooling tower to the unit is field supplied and field installed.

5) DUAL-COOL – Liebert DS Cooling Configuration

The dual-cool Liebert DS also incorporates a secondary cooling coil. This unit utilizes access to an external source for chilled water. Cooling is supplemented and improved by circulating chilled water through the secondary coil system.
