Inventor: UNO TAKASHI
IPC: F24D3/00
Filed: 1984-04-26
Abstract: PURPOSE:To save energy by making the amount of circulating hot-water variable in accordance with the load of room heating. CONSTITUTION:When room temperature is lower than a set temperature, a radiator control unit 21 drives a fan motor 18 to rotate a fan 17 and promote heat radiation. When the room temperature has arrived at the set temperature, the control unit 21 stops the motor 18. Driving signal as well as stopping signal for the motor 18 are transmitted to a sequence controller 11' also. The controller 11' dicides the load of room heating in accordance with the length of driving signal for the motor 18 from the radiator control unit 21 and changes the operating speed of a variable speed circulating pump 7'. According to the change of operating speed, the heat energy of hot-water in the boiler body of a gas boiler is radiated in accordance with the load of room heating while an electric power consumption in accordance with the revolving speed of the pump 7' is changed. The energy release of hot-water and the electric power consumption of the circulating pump may be saved in case the load of room heating is reduced when it is compared with a case wherein a constant speed pump is employed.
