This part of EN 16905 specifies the calculation of the seasonal performance factor for gas-fired endothermic engine driven heat pumps for heating and/or cooling mode including the engine heat recovery, to be used outdoors.
This document only applies to appliances with a maximum heat input (based on net calorific value) not exceeding 70 kW at standard rating conditions.
This document only applies to appliances under categories I2H, I2E, I2Er, I2R, I2E(S)B, I2L, I2LL, I2ELL, I2E(R)B, I2ESi, I2E(R), I3P, I3B, I3B/P, II2H3+, II2Er3+, II2H3B/P, II2L3B/P, II2E3B/P, II2ELL3B/P, II2L3P, II2H3P, II2E3P and II2Er3P according to EN 437:2021.
This document only applies to appliances having:
a)   gas fired endothermic engines under the control of fully automatic control systems;
b)   closed system refrigerant circuits in which the refrigerant does not come into direct contact with the fluid to be cooled or heated;
c)   where the temperature of the heat transfer fluid of the heating system (heating water circuit) does not exceed 105 °C during normal operation;
d)   where the maximum operating pressure in the:
1)   heating water circuit (if installed) does not exceed 6 bar,
2)   domestic hot water circuit (if installed) does not exceed 10 bar.
This document applies to GEHP appliances only when used for space heating or space cooling or for refrigeration, with or without heat recovery.
This document is applicable to GEHP appliances that are intended to be type tested. Requirements for GEHP appliances that are not type tested would need to be subject to further consideration.

Pompes à chaleur à moteur endothermique alimenté au gaz -Partie 5 : Calcul des performances saisonnières en modes chauffage et refroidissement

La présente partie de l'EN 16905 décrit le calcul du facteur de performance saisonnière des pompes à chaleur à moteur endothermique alimenté au gaz pour le mode chauffage et/ou refroidissement, y compris la récupération de chaleur du moteur, qui doivent être utilisées en extérieur.
Le présent document ne s'applique qu'aux appareils dont le débit calorifique maximal (dérivé du pouvoir calorifique inférieur) ne dépasse pas 70 kW dans les conditions de performance nominale.
Le présent document se limite également aux appareils classés dans les catégories I2H, I2E, I2Er, I2R, I2E(S)B, I2L, I2LL, I2ELL, I2E(R)B, I2ESi, I2E(R), I3P, I3B, I3B/P, II2H3+, II2Er3+, II2H3B/P, II2L3B/P, II2E3B/P, II2ELL3B/P, II2L3P, II2H3P, II2E3P et II2Er3P de l'EN 437:2021.
Le présent document ne s'applique qu'aux appareils :
a)   équipés de moteurs endothermiques alimentés au gaz régulés par des systèmes de régulation entièrement automatisés ;
b)      comportant des circuits fermés de réfrigérant dans lesquels le réfrigérant n'entre pas en contact direct avec le fluide à refroidir ou à chauffer ;
c)   dans lesquels la température du fluide caloporteur du système de chauffage (circuit d'eau de chauffage) ne dépasse pas 105 °C dans les conditions normales de fonctionnement ;
d)   dans lesquels la pression maximale de fonctionnement :
1)   ne dépasse pas 6 bar dans le circuit d'eau de chauffage (le cas échéant) ; et
2)   ne dépasse pas 10 bar dans le circuit d'eau chaude sanitaire (le cas échéant).
Le présent document s'applique aux appareils GEHP utilisés uniquement pour le chauffage de locaux, le refroidissement de locaux ou la réfrigération, avec ou sans récupération de chaleur.
Le présent document s'applique aux appareils GEHP destinés à être soumis à des essais de type. Les exigences relatives aux appareils GEHP non soumis à des essais de type pourraient être assujetties à des considérations supplémentaires.
