Pumped Refrigerant Based Cooling for High Heat Density Applications The Liebert XDH in-the-row cooling module is placed directly in line with the rack enclosures, and requires very little floorspace. Air from the hot aisle is drawn in through the rear of the unit, cooled, and then discharged horizontally through the front of the unit into the cold aisle. The XDH draws directly from the hot aisle, allowing the unit to take advantage of higher heat transfer efficiency. Available with Smart Module integrated control board, for increased module control and monitoring. The Liebert XDH is a part of our high heat-density cooling product family that utilizes pumped refrigerant technology. The pumped refrigerant operates at low pressure in the system and becomes a gas at room conditions, making it ideal for use around electronic equipment. Since the Liebert XD system always provides 100% sensible capacity, the need for humidification is significantly reduced, further reducing energy usage and maintenance. The modular and adaptive design of the Liebert XDH unit also allows it to be easily added as the demand for cooling increases.
Smart Module technology Liebert XDH Smart Modules include integrated control boards that provide the following capabilities: Save energy by shedding up to two fans -one on the top bank of fans, one on the lower bank of fans, based on the supply and return air temperature at the module Monitor the status of individual fans on the module with an on-unit, red/green LED Be alerted to the presence of condensation Remotely shutdown the module via dry contact closures
When a building chilled water system is available, the Liebert XDP Pumping Unit is utilized as an interface between the pumped refrigerant circuit and the chilled water system. Both the Liebert XDC and the XDP units circulate the refrigerant to Liebert XD units, while maintaining the refrigerant at a temperature always above the actual dewpoint.
