Description
Verhältnis der Dichte des Wärmestroms, der im stationären Zustand durch das Bauelement fliesst, zur Differenz der beiden Aussen- und Raumtemperaturen.
Description
Heat flow rate in the steady state divided by area and by the temperature difference between the surroundings on each side of a system.
Description
Quotient du flux thermique par unité de surface, en régime stationnaire, par la différence de température entre les milieux situés de part et d'autre d'un système.
Description
Rapporto tra la densità di flusso termico che attraversa l’elemento costruttivo in situazione stazionaria e la differenza tra le temperature degli ambienti che limitano l’elemento.

Linguistic Context
Der U-Wert wird vor allem verwendet, um einen Bauteil hinsichtlich seiner Wärmedämmfähigkeit beurteilen zu können.
Linguistic Context
Il coefficiente U viene utilizzato soprattutto per poter valutare un elemento costruttivo in rapporto alla sua capacità di isolamento termico.
Term Note
EXP: Formelzeichen = U; Masseinheit = W/(m2 · K) (a); der Wärmedurchgangskoeffizient ist kein materialspezifischer Wert, sondern eine Grösse zur Ermittlung wärmeschutztechnischer Kennzahlen für Bauteile (b)
Term Note
EXP: symbol = U; unit = W/(m2·K)
Term Note
EXP: symbole = U; unité de mesure = W/m2K (a); plus la valeur du coefficient est faible, plus la construction sera isolée (b)
Term Note
EXP: simbolo = U; unità di misura = W/(m2 · K) (a); il coefficiente U non è una proprietà specifica del materiale, bensì una grandezza usata per calcolare parametri caratteristici dei materiali isolanti (b)
