CONTROL DEVICE OF HOT-WATER STORAGE TYPE ELECTRIC HOT-WATER HEATER

摘要

PURPOSE:To contrive to utilize the performance of the titled heater according to the actual requirement of user by a method wherein the necessary amount of heat required to be stored in a hot-water storage tank is calculated based on the actual amount of the hot-water consumed by the user and the predetermined necessary amount for the next day inputted by an inputting device. CONSTITUTION:The amount of heat KG for the required amount of hot-water of the day is obtained with a necessary amount of heat calculating device 16, the data is inputted into a memory device 12, simultaneously, the predetermined necessary amount of hot-water for the next day is selected from among the previously prepared control pattern, then inputted by an inputting device 18. Therefore, a time switch 8 is made ON at midnight, then a control is started. At first, the maximum data KGmax is called from among the up-to-date data by the memory device 12, a necessary amount of heat KS is preset by a necessary amount of heat presetting device 13. A heating up temperature To is preset based on a water supply temperature Ti in a hot-water storage tank 1 and the storage tank capacity Vt. Thus, a central control device transmits the energizing start signal to each heater for levelling of load through the entire time zone of midnight electric power supply service time zone.
