Title (EN) CONTROLLING UNDER SURFACE HEATING/COOLING
(FR) COMMANDE D'UN CHAUFFAGE/REFROIDISSEMENT SOUS LA SURFACE
Abstract: front page image
(EN)Controlling under surface heating/cooling by supplying liquid to at least two supply loops in an under surface heating/cooling system, and controlling the flow of the liquid on and off such that during the duty cycle the flow is high and between the duty cycles the flow is off. Room temperature is controlled by controlling the percentage of the duty cycles, which percentage is determined on the basis of the heating demand of the rooms. Different loops are con¬ trolled such that at least in two different loops the duty cycles start at different moments.
(FR)L'invention concerne la commande d'un chauffage/refroidissement sous la surface, par la délivrance d'un liquide à au moins deux boucles d'alimentation dans un système de chauffage/refroidissement sous la surface et la commande de l'alimentation et l'arrêt de l'écoulement du liquide de telle sorte que, pendant le cycle de service, l'écoulement est élevé, et, entre les cycles de service, l'écoulement est arrêté. La température ambiante est régulée par commande du pourcentage des cycles de service, lequel pourcentage est déterminé sur la base de la demande en chauffage des salles. Différentes boucles sont commandées de telle sorte qu'au moins dans deux boucles différentes, les cycles de service commencent à des moments différents.
