Title: Controller for hot water supplying apparatus
Inventor: ADACHI IKURO
IPC: F24H1/10
Filed: 1988-09-06
Abstract: PURPOSE:To correct the time delay of a feedback due to the increase or decrease in water quantity and to uniformly evaluate an integration correcting amount over the whole water quantity by providing variation amount in the correcting amount by integration control means proportionally to water quantity. CONSTITUTION:Difference (deviation amount) between a set temperature Ts set by a controller 44 and hot water temperature To detected by a fed hot water temperature sensor 53 is corrected by an integration control with an integration correcting amount I, and an integration constant is so set to (b)XW that the variation amount of the amount I is proportional to water quantity W. The calculation of the amount I is represented by an equation of In=In-1+ bWn(Ts-To), where FFn is feed-forward amount calculated this time. If the water quantity W is large, the flowing speed of water flowing through a heat exchanger 33 is fast, and the time delay of a feedback is small. Thus, when a deviation amount is generated between the temperatures Ts and To in a state that the quantity W is large, the variation amount of the amount I is increased in response to the large quantity W by setting the integration constant to bXW. That is, the amount I is increased in response to the increase in the quantity W.
