Direct-to-Chip-Flüssigkeitskühlung: Die Zukunft des Wärmemanagements in Rechenzentren mit hoher Dichte
Die Leistungsdichte von Rechenzentren ist auf 12–30 kW pro Rack gestiegen, was eine Flüssigkeitskühlung unerlässlich macht. Erfahren Sie, wie einphasige und zweiphasige Direct-to-Chip-Systeme funktionieren, welche Kältemittelauswahlkriterien es gibt und welche wichtigen Designüberlegungen für Schläuche, Rohre und Kupplungen in modernen Rechenzentren mit hoher Dichte zu beachten sind.
Kanalluftstromausgleich
Das Ausgleich von Luftsystemen (Kanälen) kann auf verschiedene Weise erreicht werden. Die häufigste Methode, um das Ausgleich von Kanälen zu erreichen, ist eine proportionale Methode. Jeder Diffusor wird angepasst, um den richtigen Prozentsatz des Gesamtluftvolumens in der Kanäle zu liefern.
Ventileigenschaften
Why do we need to be aware of the valve characteristics? Every component in a hydronic system has some level of influence on the control and performance of a hydronic system. Valves are key because they are the controlling devices at the critical areas of heat transfer.

Dies ist eine fünf -Reihe von Veröffentlichungen, die das Kühlhandbuch für Kühlung von Emerson Climate Technologies, Inc. umfassen. Obwohl jeder getrennte Teil einen bestimmten Bereich der Kühltheorie und -praxis abdeckt, setzt jede aufeinanderfolgende Veröffentlichung ein grundlegendes Verständnis des in den vorherigen Abschnitten dargestellten Materials voraus.
Eisspeichersysteme
Thermische Energiespeicher (TEs) beinhaltet das Hinzufügen von Wärmeenergie (thermische) Energie zu einem Speichermedium und dann zu einem anderen Zeitpunkt aus diesem Medium. Dies kann das Speichern von Wärmeenergie bei hohen Temperaturen (Wärmespeicher) oder bei niedrigen Temperaturen (Kühllager) beinhalten.

This guide focuses on systems that use Refrigerant-22 (R-22). While the general requirements are the same for systems that use other refrigerants, velocities and pressure drops will differ.
Lebenszykluskostenanalysemethode
The life-cycle cost analysis method is the most commonly accepted method to assess the economic benefits of energy conservation projects over their lifetime. Typically, the method is used to evaluate at least two alternatives of a given project (for instance, evaluate two alternatives for the installation of a new HVAC system: a VAV system or a heat pump system to condition the building). Only one alternative will be selected for implementation based on the economic analysis.
