Abstract[English]
To increase energy efficiency while cooling equipment in the computer data center, a refrigerant flowing through a first heat exchanger (1) is at least partially directed to flow through a second heat exchanger (20) before being directed to a refrigerant return line (5). The first heat exchanger (1) is configured to cool air used for air-cooling the equipment and the second heat exchanger (20) is configured to cool liquid used for liquid-cooling of the equipment. The system and the method aim to increase the heat-exchanging efficiency of cooling the data center.[French]
Pour augmenter l'efficacité énergétique tout en refroidissant un équipement dans le centre de données informatiques, un fluide frigorigène s'écoulant à travers un premier échangeur de chaleur (1) est au moins partiellement dirigé pour s'écouler à travers un second échangeur de chaleur (20) avant d'être dirigé vers une ligne de retour de fluide frigorigène (5). Le premier échangeur de chaleur (1) est conçu pour refroidir l'air utilisé afin de refroidir l'équipement et le second échangeur de chaleur (20) est conçu pour refroidir le liquide utilisé pour le refroidissement par liquide de l'équipement. Le système et le procédé visent à augmenter l'efficacité d'échange de chaleur de refroidissement du centre de données.
