Compressors and condensing units for refrigeration - Performance testing and test methods - Part 2: Condensing units
This European Standard applies only to condensing units for refrigeration and describes a number of selected performance test methods. These methods provide sufficiently accurate results for the determination of the refrigerating capacity, power absorbed, refrigerant mass flow and the coefficient of performance.
This European Standard applies only to performance tests conducted at the manufacturer's works or wherever the instrumentation and load stability for testing to the accuracy required is available.

Compresseurs et unités de condensation pour la réfrigération - Essais de performance et méthodes d'essais - Partie 2 : Unités de condensation
La présente Norme européenne s’applique uniquement aux unités de condensation pour la réfrigération et décrit une sélection de méthodes d’essai des performances. Ces méthodes fournissent des résultats d’une exactitude suffisante pour déterminer la puissance frigorifique, la puissance absorbée, le débit masse du fluide frigorigène et le coefficient de performance.
La présente Norme européenne s’applique uniquement aux essais de performance conduits dans les usines des fabricants ou en des endroits où l’on dispose de l’instrumentation et d’une stabilité de charge permettant d’effectuer les essais avec l’exactitude requise.
Kompresorji in kondenzacijske enote za hladilne naprave - Preskušanje lastnosti in preskusne metode - 2. del: Kondenzacijske enote
Ta evropski standard se uporablja samo za kondenzatorske enote za hlajenje in opisuje izbrane metode za preskušanje zmogljivosti. Te metode zagotavljajo dovolj natančne rezultate za določanje zmogljivosti hlajenja, porabe energije, pretoka hladilne tekočine in koeficienta zmogljivosti.
Ta evropski standard se uporablja le pri preskušanju lastnosti v tovarni proizvajalca ali povsod, kjer so na voljo instrumenti in stabilnost bremena za preskušanje pri zahtevani natančnosti.
