CONTROL METHOD FOR HOT-WATER SUPPLY HEADER

摘要

PROBLEM TO BE SOLVED: To provide a control method for a hot-water supply header capable of maintaining hot-water supply temperatures to respective hot-water supply destinations at a predetermined temperature by minimizing temperature change even when hot-water supply usage is carried out at two or more hot-water supply destinations at the same time.;SOLUTION: In a single hot-water supply using state with respect to only one hot-water supply destination, a mixing process cycle R1 is continuously repeated in regard to mixing ratio adjustment of a mixing valve corresponding to the hot-water supply destination to carry out a mixing control routine (a). In a concurrent hot-water supply using state wherein hot-water supply usage to another hot-water supply destination is additionally newly started, the mixing process cycle R1 and a mixing process cycle R3 regarding mixing ratio adjustment of a mixing valve corresponding to the new hot-water supply destination are serially and alternately repeated in order (b). The respective mixing process cycles R1 and R3 are mutually repeated with time intervals of a cycle time (100msec) of the other mixing process cycle to mitigate rapid and abrupt change of a mixing ratio.;COPYRIGHT: (C)2004,JPO
