Title (EN) A COOLING SYSTEM, A CONTROL METHOD THEREOF AND A MACHINE ROOM
(FR) SYSTÈME DE REFROIDISSEMENT, PROCÉDÉ DE COMMANDE ET SALLE DES MACHINES
(ZH) 一种散热系统、控制方法及机房
Abstract: front page image
(EN)A cooling system includes a heat exchanger (301) buried under ground, a first air-liquid heat exchanger (302), a second air-liquid heat exchanger (303), a controller (304), a fluid conveying means (305), and connecting pipes (307). A control method used in the cooling system includes steps: obtaining at least one surrounding information including temperature out of the machine room, and soil temperature surrounding the buried pipes, controlling the opening of corresponding circulation paths according the preset control strategy and the obtained surrounding information, opening at least one of the circulation paths, cooling by means of flow of the circulation fluid in the opened circulation paths. A machine room using the cooling system is also disclosed.
(FR)L'invention concerne un système de refroidissement qui comprend un échangeur de chaleur (301) enfoui dans le sol, un premier échangeur de chaleur (302) air-liquide, un second échangeur de chaleur (303) air-liquide, un organe de commande (304), des moyens de transport de fluide (305) et des tuyaux de raccordement (307). Le procédé de commande utilisé dans le système refroidissement comprend les étapes suivantes: obtenir au moins des données relatives à l'environnement, y compris la température à la sortie de la salle des machines et la température du sol entourant les tuyaux enfouis; régler l'ouverture des trajets de circulation correspondants selon la stratégie de commande préétablie et les données d'environnement obtenues; ouvrir au moins un des trajets de circulation; mettre en œuvre un refroidissement par l'écoulement du fluide circulant dans les trajets de circulation ouverts. L'invention concerne aussi une salle des machines utilisant ce système de refroidissement.
