Abstract

La présente invention porte sur un procédé de protection contre le gel d'une chaudière à gaz, lequel procédé peut empêcher un tuyau de chauffage de geler par l'utilisation d'un capteur de température d'eau de chauffage qui est disposé dans la chaudière et peut empêcher un tuyau d'eau chaude de geler par la commande d'une vanne à trois voies. Le procédé de protection contre le gel pour un tuyau de chauffage et un tuyau d'eau chaude d'une chaudière comprend les étapes consistant à : (a) convertir la vanne à trois voies (120) dans un mode d'eau chaude et effectuer une opération de combustion de la chaudière, si la température de l'eau de chauffage chute en dessous d'une température de consigne de protection contre le gel prédéfinie, et faire circuler l'eau de chauffage à travers une boucle fermée comprenant un échangeur de chaleur de chauffage (110), la vanne à trois voies (120) et un échangeur de chaleur d'alimentation en eau chaude (130) par entraînement d'une pompe de circulation (140) ; et (b) convertir la vanne à trois voies (120) dans un mode de chauffage et effectuer une opération d'extinction de la chaudière, si la température de l'eau de chauffage est supérieure à une certaine température prédéfinie, et faire circuler l'eau de chauffage vers le tuyau de chauffage (200) par l'entraînement de la pompe de circulation (140). Par conséquent, en plus d'une fonction de protection contre le gel pour le tuyau de chauffage, un gel du tuyau d'eau chaude peut être empêché, de façon à remédier ainsi à un inconvénient de l'utilisation d'eau chaude dû au gel du tuyau d'eau chaude pendant l'hiver. Également, comme il est inutile d'effectuer de façon continue l'opération de combustion de la chaudière pour empêcher le tuyau de chauffage et le tuyau d'eau chaude de geler, il n'y a pas de différence significative dans la quantité de gaz utilisée par rapport à des fonctions de protection contre le gel existantes.
