Dieses Dokument legt die Begriffe, die Prüfbedingungen und die Prüfverfahren für die Bewertung und die Leistung von Dachgeräten fest. Es legt zudem die Leistungsbestimmung und die Berechnungsverfahren unter Berücksichtigung der Merkmale von Dachgeräten, wie freie Kühlung und Mischung von Luftströmen, zur Ermittlung der saisonalen Arbeitszahl bei Kühl- und Heizbetrieb fest. Dieses Dokument behandelt nur Raumheizung und/oder kühlung für Komfortzwecke (Prozessanwendungen liegen nicht im Anwendungsbereich dieses Dokuments). Es ist anwendbar für Luft/Luft- und Wasser/Sole-Luft-Dachgeräte mit elektrisch angetriebenem/n Verdichter(n), die mit einem zusätzlichen Heizgerät ausgestattet sein können und einen elektrischen Widerstand oder die Verbrennung fossiler Brennstoffe verwenden.
