Title: Hot water supplier with space heating function
Inventor: EGAMI TOYOHIKO
IPC: F24H1/44
Filed: 1987-07-31
Abstract: PURPOSE:To prevent the fluctuation of the temperature on the space heating side by a single blower at the time of the simultaneous operation of hot water supply and space heating by setting the space heating side on which an optimum combustion quantity is determined dependent on the draft quantity due to the ability of the hot water supply side, and setting the combustion stop temperature on the space heating side slightly lower than that at the time of a single operation. CONSTITUTION:The operation of the hot water supply side, when the operation on the hot water supply side is carried out simultaneously, is set to an on-off operation, and the hot water supply side continues to carry out a proportional control operation. When the hot water supply side is placed in a simultaneous operation, the necessary draft quantity is greatly increased by the combustion on the hot water supply side, and accordingly the draft quantity distributed to the space heating side is greatly increased. Since the combustion on the space heating side becomes strong in accordance with the increase in the draft quantity distributed, the temperature adjustment on the space heating side is carried out. In the case where the hot water temperature adjustment on the space heating side is set to To and the operation on the hot water supply side is carried out, the combustion stop temperature on the space heating side is set to a temperature which is lower than the set hot water temperature To by DELTAT. Therefore, if the hot water temperature T exceeds To-DELTAT, the combustion is stopped.
