(Main)Heat pumps with electrically driven compressors - Testing, performance rating and requirements for marking of domestic hot water units
Heat pumps with electrically driven compressors - Testing, performance rating and requirements for marking of domestic hot water units
This European Standard specifies methods for testing, rating of performance and calculation of water heating energy efficiency of air/water, brine/water, water/water and direct exchange/water heat pump water heaters and heat pump combination heaters with electrically driven compressors and connected to or including a domestic hot water storage tank for domestic hot water production.
NOTE 1 Testing procedures for simultaneous operation for domestic hot water production and space heating are not treated in this standard. Simultaneous means that domestic hot water production and space heating generation occur at the same time and may interact.
This European Standard comprises only the testing procedure for the domestic hot water production of the heat pump system.
NOTE 2 For heat pump combination heaters the seasonal efficiency of space heating is determined according to EN 14825.
This European Standard only applies to water heaters which are supplied in a package of heat pump and storage tank. In the case of water heaters consisting of several parts with refrigerant connections, this European Standard applies only to those designed and supplied as a complete package.
This European Standard does not specify requirements of the quality of the used water.
Wärmepumpen mit elektrisch angetriebenen Verdichtern - Prüfungen, Leistungsbemessung und Anforderungen an die Kennzeichnung von Geräten zum Erwärmen von Brauchwarmwasser
Diese Europäische Norm legt Verfahren zur Prüfung, Bewertung der Leistung und Berechnung der Energie-effizienz beim Erwärmen des Wassers für Wärmepumpen Wassererwärmer und Kombi Wärmepumpen-Heizgeräte mit elektrisch angetriebenen Verdichtern, die mit einem Speicher für Brauchwarmwasser verbunden sind oder einen solchen enthalten, bei Luft/Wasser, Sole/Wasser, Wasser/Wasser und Direkt-austausch/Wasser für die sanitäre Warmwasserbereitung fest.
ANMERKUNG 1 Prüfverfahren für die gleichzeitige sanitäre Warmwasserbereitung und Raumheizung werden in dieser Norm nicht behandelt. Gleichzeitig bedeutet, dass die sanitäre Warmwasserbereitung und die Wärmeerzeugung für die Raumheizung zur gleichen Zeit erfolgen und in Wechselwirkung treten dürfen.
Diese Europäische Norm umfasst nur das Prüfverfahren für die sanitäre Warmwasserbereitung des Wärme-pumpensystems.
ANMERKUNG 2 Für Kombi Wärmepumpen Heizgeräte wird die saisonale Arbeitszahl der Raumheizung nach EN 14825 bestimmt.
Diese Europäische Norm gilt nur für Wassererwärmer, die als Verbundanlage aus Wärmepumpe und Warm-wasserspeicher geliefert werden. Bei Wassererwärmern, die aus mehreren Teilen mit Kältemittelanschlüssen bestehen, gilt diese Europäische Norm nur für die Geräte, die als vollständige Einheit konstruiert und geliefert werden.
Diese Europäische Norm legt keine Anforderungen an die Qualität des gebrauchten Wassers fest.
Pompes à chaleur avec compresseur entraîné par moteur électrique - Essais, détermination des performances et exigences pour le marquage des appareils pour eau chaude sanitaire
La présente Norme européenne spécifie les méthodes d’essai, la détermination des performances et le calcul de l’efficacité énergétique pour le chauffage de l’eau des dispositifs de chauffage de l’eau par pompe à chaleur air/eau, eau glycolée/eau, eau/eau et détente directe/eau et des dispositifs de chauffage mixte par pompe à chaleur équipés de compresseurs entraînés par moteur électrique et raccordés ou intégrés à un réservoir de stockage d’eau chaude sanitaire pour la production d’eau chaude sanitaire.
NOTE 1 Les procédures d’essai applicables simultanément à la production d’eau chaude sanitaire et au chauffage des locaux ne sont pas traitées dans la présente norme. Le terme « simultanément » signifie que la production d’eau chaude sanitaire et la génération du chauffage des locaux s’effectuent en même temps et peuvent interagir.
La présente Norme européenne ne comprend que les procédures d’essai pour la production d’eau chaude sanitaire par le système de pompe à chaleur.
NOTE 2 Pour les dispositifs de chauffage mixte par pompe à chaleur, l’efficacité saisonnière pour le chauffage des locaux est déterminée conformément à l’EN 14825.
La présente Norme européenne s’applique uniquement aux chauffe-eau qui sont fournis sous forme d’ensemble comprenant une pompe à chaleur et un réservoir de stockage. Dans le cas de chauffe-eau composés d’éléments séparés avec des branchements de fluide frigorigène, la présente Norme européenne ne s’applique qu’aux appareils conçus et fournis comme un ensemble.
La présente Norme européenne ne spécifie pas d’exigences sur la qualité de l’eau utilisée.
Toplotne črpalke z električnimi kompresorji - Preskušanje, vrednotenje lastnosti in zahteve za označevanje naprav za pripravo tople sanitarne vode
Ta evropski standard določa metode za preskušanje, vrednotenje zmogljivosti in izračun energetske učinkovitosti ogrevanja kombinacij zrak/voda, slanica/voda, voda/voda in neposredna izmenjava/voda grelnikov vode s toplotno črpalko ter kombiniranih grelnikov s toplotno črpalko z električno gnanimi kompresorji, ki so povezani z ali vključujejo rezervoar za toplo sanitarno vodo za proizvodnjo tople sanitarne vode.
OPOMBA 1:Ta standard ne obravnava preskusnih postopkov za sočasno delovanje proizvodnje tople sanitarne vode in ogrevanja prostorov. Sočasno pomeni, da proizvodnja tople sanitarne vode in ogrevanje prostorov potekata ob istem času, pri čemer lahko pride do medsebojnega vpliva.
Ta evropski standard zajema le preskusni postopek za proizvodnjo tople sanitarne vode s sistemom toplotne črpalke.
OPOMBA 2: Pri kombiniranih grelnikih s toplotno črpalko se sezonska učinkovitost ogrevanja prostorov določi v skladu s standardom EN 14825.
Ta evropski standard se uporablja samo za grelnike vode, ki so dobavljeni v kompletu s toplotno črpalko in rezervoarjem za vodo. Pri grelnikih vode, ki so sestavljeni iz več delov, s priključki za hladilno sredstvo se ta evropski standard uporablja samo za tiste, ki so zasnovani in dobavljeni kot celoten komplet.
Ta evropski standard ne določa zahtev za kakovost uporabljene vode.

1 Scope
This European Standard specifies methods for testing, rating of performance and calculation of water heating
energy efficiency of air/water, brine/water, water/water and direct exchange/water heat pump water heaters
and heat pump combination heaters with electrically driven compressors and connected to or including a domestic
hot water storage tank for domestic hot water production.
NOTE 1 Testing procedures for simultaneous operation for domestic hot water production and space heating are not treated
in this standard. Simultaneous means that domestic hot water production and space heating generation occur at the same time
and may interact.
This European Standard comprises only the testing procedure for the domestic hot water production of the heat
pump system.
NOTE 2 For heat pump combination heaters the seasonal efficiency of space heating is determined according to EN 14825.
This European Standard only applies to water heaters which are supplied in a package of heat pump and storage
tank. In the case of water heaters consisting of several parts with refrigerant connections, this European Standard
applies only to those designed and supplied as a complete package.
This European Standard does not specify requirements of the quality of the used water.
