Storing hot water type electric calorifier

摘要

PURPOSE: To heat only necessary hot water quantity and to reduce energy loss by continuing an operation until a heating hot water amount calculated by a heating hot water amount calculator becomes a set value of hot water amount setting means. ;CONSTITUTION: When hot water of a predetermined temperature is stored from an upper part of a hot water reservoir 1 to a position of hot water amount sensing means 8, a signal is sent to a heating hot water calculator 10. Then, calculation of a heating circulating flow rate and its integration are started from inputs of a heater 4, first temperature detecting means 5 and second temperature detecting means 6, and a heating hot water amount is calculated. Thereafter, the calculator 10 repeatedly integrates until a difference of the hot water amounts previously clarified by a set value of hot water amount setting means 9 and a signal or the means 8 is eliminated. When it reaches the set value, a signal is sent to a controller 11, which stops operations of a circulating pump 2 and a heater 4. Accordingly, since a necessary amount can be stored by a simple apparatus, an energy conservation apparatus corresponding to a hot water supply load can be provided.;COPYRIGHT: (C)1994,JPO
