Scope of work

Die aus dem Jahr 2001 stammende Kältezentrale im Gebäude CHN soll erneuert und erweitert werden. Die neue Kältezentrale wird an den geplanten Kältering angeschlossen, welche das gesamte ETH Zentrum mit Kälteenergie versorgt. Es werden drei neue NH3-Kältemaschinen erstellt (tot. 4.3 MW Kälteleistung), mit der Möglichkeit zum Ausbau mit einer vierten Maschine. Die Abwärme wird über einen Kühlturm und drei Hybridrückkühler abgeführt.

Es sind die Elektroinstallationen für die Kältemaschinen, Rückkühlung und Anlagen der Gebäudetechnik (HLKS/GA) zu erstellen. Sämtliche Arbeiten finden im laufenden Betrieb statt. Die Elektroinstallationen müssen auf die neue Situation angepasst, erweitert und grösstenteils neu verkabelt werden.
