Generally, apparatuses, systems, and methods are described to vent refrigerant vapor from the refrigerant pump line using a vent line, such as during priming of the pump and/or during a startup of the compressor, directed to a relatively reduced volute casing mass of the refrigerant pump, and/or directed to returning refrigerant to an economizer or chiller component other than the condenser. L'invention concerne, d'une manière générale, des appareils, des systèmes et des procédés qui permettent la ventilation des vapeurs de fluide frigorigène d'une conduite de pompe de fluide frigorigène au moyen d'une conduite de ventilation, tel que pendant l'amorçage de la pompe et/ou pendant un démarrage du compresseur, ainsi que l'obtention d'une masse de volute relativement réduite de la pompe de fluide frigorigène et/ou le retour du fluide frigorigène vers un élément économiseur ou refroidisseur autre que le condenseur.
