Abstract
(EN)
An air and coolant control system comprising: a heat source configured to receive air, generate heat, receive coolant, conduct the received coolant to a coolant outlet, and transfer the generated heat to the received coolant, thereby removing the generated heat from the heat source as the coolant is conducted out of the heat source; an air supply source configured to supply the air to the heat source; an air supply control system configured to adjust the supply of air from the air supply source to the heat source based on a dynamic feedback temperature characteristic from the heat source; a coolant supply source configured to supply the coolant to the heat source; and a coolant control system configured to adjust the flow rate of the coolant based on an estimated feed-forward heat source characteristic and to adjust the temperature of the coolant based on the dynamic feedback temperature characteristic.
(FR)
L'invention concerne un système de régulation d'air et de frigorigène qui comporte : une source de chaleur configurée pour recevoir de l'air, pour générer de la chaleur, pour recevoir du frigorigène, pour conduire le frigorigène reçu vers une sortie de frigorigène et pour transférer la chaleur générée vers le frigorigène reçu, éliminant ainsi la chaleur générée de la source de chaleur lorsque le frigorigène est conduit à l'extérieur de la source de chaleur; une source d'alimentation en air configurée pour alimenter de l'air vers la source de chaleur; un système de régulation d'alimentation en air configuré pour ajuster l'alimentation d'air depuis la source d'alimentation d'air vers la source de chaleur sur la base d'une caractéristique de température de rétroaction dynamique provenant de la source de chaleur; une source d'alimentation en frigorigène configurée pour alimenter le frigorigène vers la source de chaleur; et un système de régulation de frigorigène configuré pour ajuster le débit d'écoulement du frigorigène sur la base d'une caractéristique de source de chaleur à avance directe estimée et pour ajuster la température du frigorigène sur la base de la caractéristique de température de rétroaction dynamique.
