Title (EN) A PUMP AND AN ENERGY RECOVERY APPARATUS FOR A REFRIGERATION SYSTEM
(FR) POMPE ET APPAREIL DE RÉCUPÉRATION D'ÉNERGIE POUR UN SYSTÈME DE RÉFRIGÉRATION
Abstract:
(EN) A pump is described comprising first and second chambers each having an inlet and an outlet. The inlet of each chamber is selectively in fluid communication with an inlet line and the outlet of each chamber is selectively in fluid communication with an outlet line. First and second valve means provided to selectively place each chamber in fluid communication with gas at a pressure comparable to pressure in the inlet line or with gas at a pressure comparable to pressure in the outlet line. Pressure equalisation means selectively equalises fluid pressure in the first and second chambers. An energy recovery system using the pump for use in a refrigeration system is also described.
(FR) L'invention concerne une pompe, qui comprend des première et seconde chambres comprenant chacune une entrée et une sortie. L'entrée de chaque chambre est en communication fluidique sélective avec une ligne d'entrée et la sortie de chaque chambre est en communication fluidique sélective avec une ligne de sortie. Des premier et second moyens formant vanne sont disposés de façon à mettre de façon sélective chaque chambre en communication fluidique avec un gaz à une pression comparable à la pression dans la ligne d'entrée ou avec un gaz à une pression comparable à la pression dans la ligne de sortie. Des moyens d'égalisation de pression égalisent de manière sélective une pression de fluide dans les première et seconde chambres. L'invention concerne également un système de récupération d'énergie utilisant la pompe lors d'une utilisation dans un système de réfrigération.
