Row Level Air-to-Liquid Cooling

 

RackChiller In-Row Precision Cooler

nVent SCHROFF RackChiller In-Row chilled water heat exchanger is a modular and scalable precision cooling solution that can replace or supplement traditional data center cooling infrastructure. The RackChiller In-Row is designed to deliver localized energy efficient cooling, which includes an air-to-water heat exchanger that removes and transfers heat to a water circuit. Six integrated Electronic Commutator (EC) fans provide chilled return air to the front of the unit for localized feed to a contained row and/or adjacent IT equipment.

Features

  • Water connection from above or below

  • Built-in redundancy through EC fan technology

  • Dual A-B power feed (integrated ATS)

  • Control with internal and external sensors possible

  • Monitoring via SNMP or Modbus

  • Compatible with nVent aisle containment system

  • Available in 300 mm and 600 mm widths

 

 Benefits

  • Up to 85% efficiency improvement vs. CRAC based systems in optimal operating conditions

  • Operates with cooling water temperatures up to 84°F / 29°C while maintaining air

  • temperatures within ASHRAE A1 allowable envelope

  • Minimal planning outlay; short setup time

  • Conforms to UL STD No. 61010-1 and CSA STD C22.2 No. 61010-1

Row Level Cooling Configurations

Open Aisle

Open aisle row configuration includes a single row or dual row of cabinets that separate open cold and hot aisle, no aisle containment. The nVent SCHROFF RackChiller draws hot air from the rear of the cabinets in the hot aisle, removes the heat through an air-to-water heat exchanger and supplies cooled air to the front of IT equipment in the cold aisle.

To increase efficiency it is allways better to combine in row cooling with a containment system to minimize

air leakage.

Hot Aisle Contained Row

Hot aisle contained row configuration contains the hot exhaust air generated from IT equipment to prevent mixing with cool air in the room environment. The nVent RackChiller draws the contained hot air from the hot aisle, removes the heat through an air-to-water heat exchanger, and feeds cooled

air to the front of IT equipment in the uncontained cold aisle.

Cold Aisle Contained Row

Cold aisle contained row configuration contains chilled air provided by the Schroff RackChiller in the cold aisle to prevent mixing with hot air generated by the exhaust of equipment within the hot aisle. The nVent RackChiller draws the contained hot air from the hot aisle, removes the heat through an air-to- water heat exchanger, and feeds cooled air to the front of IT equipment in the contained cold aisle

Monitoring

  • Valve position (adjustable via cold air temperature)

  • Fan speed (adjustable via hot air temperature)

  • Return water temperature

  • Fan-function display

  • Local alarm display

  • User-defined preventative maintenance alarms

  • Alarm log

  • SNMP and Modbus interface
