Title
(EN) REFRIGERANT COOLING AND LUBRICATION SYSTEM
(FR) SYSTÈME DE REFROIDISSEMENT DE RÉFRIGÉRANT ET DE LUBRIFICATION
Abstract
(EN) Generally, apparatuses, systems, and methods are described to prime a refrigerant pump by decoupling or shielding from a condenser operation, such as for example the condenser water pump, so that liquid refrigerant can be appropriately sourced from the condenser and/or the evaporator using flow control device(s) such as a source valve on a source line of the condenser and/or on a source line of the evaporator and the control of such valve(s).
(FR) L'invention concerne généralement des appareils, systèmes et procédés pour amorcer une pompe à réfrigérant par découplage ou protection du fonctionnement d'un condenseur, tel que, par exemple, la pompe à eau de condenseur, de sorte que le réfrigérant liquide peut être approvisionné de façon appropriée à partir du condenseur et/ou de l'évaporateur au moyen d'un ou plusieurs dispositif(s) de contrôle d'écoulement tels qu'une vanne d'approvisionnement sur une conduite d'approvisionnement du condenseur et/ou sur une conduite d'approvisionnement de l'évaporateur et de la commande d'une telle ou de telles vanne(s).
