La station de réfrigération mobile comprend une unité de commande (8), une unité de réfrigération d'ammoniac et un conteneur (10). L'unité de commande (8) et l'unité de réfrigération d'ammoniac sont disposés dans le conteneur (10). L'unité de commande (8) est connecté électriquement à l'unité de réfrigération d'ammoniac et utilisé pour obtenir des paramètres d'une ou de plusieurs parties de composant de l'unité de réfrigération d'ammoniac. Le système de commande à distance comprend un terminal de commande et un serveur. Le terminal de commande est connecté à l'unité de commande (8) au moyen du serveur, et le serveur est connecté au terminal de commande de manière à obtenir une surveillance à distance de la station de réfrigération mobile.
