The present invention provides a boiler having an exhaust gas temperature control unit using a temperature sensor, the boiler comprising: a combustion and exhaust unit having a burner for combusting fuel to generate heat, an exhaust port for discharging the combustion residue outside the boiler, and an exhaust pipe connected to the exhaust port, for guiding the combustion residue into the open air; a circulation unit for circulating hot water to provide hot water and heat for the user; a heat exchange unit for absorbing the heat generated from the burner to make hot water and for supplying the hot water to the circulation part, with both ends of the heat exchange part being connected to the circulation part; and a control unit including an outlet temperature sensor arranged in the outlet of the heat exchange unit, for measuring the temperature of the hot water, an inlet temperature sensor arranged in the inlet of the heat exchange unit, for measuring the temperature of the cold water introduced from the circulation unit, and a controller for calculating the temperatures measured by the inlet and outlet temperature sensors so as to control whether to operate the boiler or not. Thus the exhaust pipe may be made of cheap PVC and the use of PVC facilitates installation. Further, the existing temperature sensors may be used to control the boiler and thus an additional control device is not needed, thereby reducing installation costs.
La présente invention porte sur une chaudière, qui a une unité de commande de température de gaz d'échappement utilisant un capteur de température, laquelle chaudière comprend : une partie de combustion et d'échappement ayant un brûleur pour brûler un carburant afin de générer de la chaleur, une ouverture d'échappement pour décharger l'échappement et les résidus à l'extérieur de la chaudière, et un tuyau d'échappement relié à l'ouverture d'échappement pour guider l'échappement et les résidus dans l'air ouvert ; une partie de circulation pour faire circuler de l'eau chaude pour fournir de l'eau chaude et de la chaleur pour l'utilisateur ; une partie d'échange de chaleur avec les deux extrémités de celle-ci reliées à la partie de circulation pour absorber la chaleur générée à partir du brûleur afin de fournir de l'eau chaude à la partie de circulation ; et une unité de commande comprenant un capteur de température de sortie disposé dans la sortie de la partie d'échange de chaleur pour mesurer la température de l'eau chaude, un capteur de température d'entrée disposé dans l'entrée de la partie d'échange de chaleur pour mesurer la température de l'eau froide venant de la partie de circulation, et un dispositif de commande pour calculer les températures mesurées par les capteurs de température d'entrée et de sortie de façon à effectuer une commande du fait qu'il faut ou non actionner la chaudière. Par conséquent, le tuyau d'échappement peut être réalisé en poly(chlorure de vinyle), moins coûteux, ce poly(chlorure de vinyle) facilitant également l'installation, et les capteurs de température existants peuvent être utilisés pour commander la chaudière de telle sorte qu'un appareil de commande additionnel n'est pas nécessaire, réduisant les coûts d'installation.
