Condensing units for refrigeration - Rating conditions, tolerances and presentation of manufacturer's performance data

This European Standard specifies the rating conditions, tolerances and presentation of manufacturer's performance data for condensing units for refrigeration with compressors of the positive-displacement type. These include single stage compressors and single and two stage compressors having an integrated means of fluid sub cooling. This is required so that a comparison of different condensing units can be made. The data relate to the refrigerating capacity and power absorbed and include requirements for part-load performance where applicable.

Verflüssigungssätze für die Kälteanwendung - Nennbedingungen, Toleranzen und Darstellung von Leistungsdaten des Herstellers

Diese Europäische Norm legt die Nennbedingungen, Toleranzen und die Darstellung der Leistungsdaten des Herstellers für Verflüssigungssätze für die Kälteanwendung mit Verdichtern des Verdrängertyps fest. Dazu gehören einstufige Verdichter sowie ein- und zweistufige Verdichter mit eingebauten Einrichtungen zur Unterkühlung von Flüssigkeiten. Dies ist notwendig, damit ein Vergleich von unterschiedlichen Verflüssigungssätzen durchgeführt werden kann. Die Daten beziehen sich auf die Kälteleistung und die Leistungsaufnahme und umfassen Anforderungen an die Teillastleistung, sofern zutreffend.

Unités de condensation pour la réfrigération - Détermination des caractéristiques, tolérances et présentation des performances du fabricant

La présente Norme européenne spécifie les conditions de détermination des caractéristiques, les tolérances et la présentation des performances des unités de condensation pour la réfrigération avec compresseurs de type volumétrique. Elles incluent les compresseurs à un ou deux étages équipés d’un système de sous-refroidissement du fluide. Ceci est nécessaire afin de permettre une comparaison entre différentes unités de condensation. Les données se rapportent à la puissance frigorifique et à la puissance absorbée et comprennent les exigences pour les performances à charge partielle, le cas échéant.

Kondenzacijske enote za hladilne naprave - Ocenjevalni pogoji, tolerance in predstavitev podatkov o lastnostih, ki jih navede proizvajalec

Ta evropski standard določa pogoje za določanje nazivne moči, toleranc in predstavitev tehničnih karakteristik proizvajalca za kondenzatorske enote za hlajenje s kompresorji z iztiskanjem. Ti vključujejo enostopenjske kompresorje ter eno- in dvostopenjske kompresorje z vgrajenim sredstvom za podhlajevanje tekočine. To je potrebno zato, da je mogoče opraviti primerjavo različnih kondenzatorskih enot. Podatki se navezujejo na zmogljivost hlajenja in absorbirano moč ter vključujejo zahteve za zmogljivost pri delni obremenitvi, kjer je to primerno.
