Heating systems in buildings - Design of heat pump heating systems
This standard specifies design criteria for heating systems in buildings using electrically driven heat pumps alone or in combination with other heat generators. Heat pump systems considered include (see Table 1):
- water - water;
- water - air;
- brine - water;
- refrigerant - water (direct expansion systems);
- refrigerant - refrigerant;
- air - air;
- air - water.
This standard takes into account the heating requirements of attached systems (e.g. domestic hot water) in the design of heat supply, but does not cover the design of these systems. This standard covers only the aspects dealing with the heat pump, the interface with the heat distribution system and heat emission system (e.g. buffering system), the control of the whole system and the aspects dealing with energy source of the system.
Systems designed primarily for cooling and systems which can operate simultaneously in cooling and heating mode are not within the scope of this standard.
Heizungsanlagen in Gebäuden - Planung von Heizungsanlagen mit Wärmepumpen
Diese Norm legt Kriterien für die Planung von Heizungsanlagen in Gebäuden fest, die entweder nur mit elektrisch betriebenen Wärmepumpen oder mit Wärmepumpen in Verbindung mit anderen Wärmeerzeugern arbeiten. Dazu gehören folgende Systeme (siehe Tabelle 1):
Wasser/Wasser;
Wasser/Luft;
Sole/Wasser;
Kältemittel/Wasser (Direktverdampfungssysteme);
Kältemittel/Kältemittel;
Luft/Luft;
Luft/Wasser.
Diese Norm berücksichtigt die für die Planung der Wärmeerzeugung maßgeblichen Heizungsanforderungen sämtlicher verbundener Systeme (z. B. Trinkwarmwasser), behandelt jedoch nicht die Planung dieser Systeme. Diese Norm behandelt nur die für die Wärmepumpe, die Schnittstelle mit dem Wärmeverteilungs und Wärmeübergabesystem (z. B. Puffersystem) und die Regelung des gesamten Systems sowie die für die Energiequelle des Systems geltenden Aspekte.
Systeme, die hauptsächlich zur Kühlung ausgelegt sind, sowie Systeme, die gleichzeitig im Kühl und Heizbetrieb laufen können, liegen nicht im Anwendungsbereich dieser Norm.
Systèmes de chauffage dans les bâtiments - Conception des systèmes de chauffage par pompe à chaleur
La présente norme spécifie les critères de conception des systèmes de chauffage dans les bâtiments qui utilisent des pompes à chaleur à moteur électrique seules ou combinées à d’autres générateurs de chaleur. Les systèmes de chauffage par pompe à chaleur suivants sont pris en compte (voir Tableau 1) :
eau eau ;
eau air ;
eau glycolée eau ;
fluide frigorigène eau (systèmes à détente directe) ;
fluide frigorigène fluide frigorigène ;
air air ;
air eau.
La présente norme tient compte des besoins en chauffage des systèmes auxiliaires (par exemple, eau chaude sanitaire) dans la conception de la production de chaleur, mais ne couvre pas la conception de ces systèmes. La présente norme couvre uniquement les aspects concernant la pompe à chaleur, l’interface avec le système de distribution de chaleur et le système d’émission de chaleur (par exemple, le système tampon) et la régulation de l’ensemble du système, ainsi que les aspects liés à la source d’énergie du système.
Les systèmes conçus principalement pour le refroidissement et les systèmes qui peuvent fonctionner soit en mode de refroidissement soit en mode de chauffage n’entrent pas dans le cadre la présente norme.

Where possible, reference is made to other European or International Standards, a.o. product standards. However, use of products complying with relevant product standards is no guarantee of compliance with the system requirements. The requirements are mainly expressed as functional requirements, i.e. requirements dealing with the function of the system and not specifying shape, material, dimensions or the like.
The guidelines describe ways to meet the requirements, but other ways to fulfil the functional requirements might be used if fulfilment can be proved. Heating systems differ among the member countries due to climate, traditions and national regulations. In some cases requirements are given as classes so national or individual needs may be accommodated. In cases where the standards contradict with national regulations, the latter should be followed. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.
