METHOD OF DETECTING FAILURE OF WATER SUPPLY FLOW RATE SENSOR OF HOT WATER STORAGE TYPE HOT WATER SUPPLY SYSTEM, AND HOT WATER STORAGE TYPE HOT WATER SUPPLY SYSTEM USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a hot water storage type hot water supply system capable of notifying a user of the failure with a simple constitution when a water supply flow rate sensor is failed.;SOLUTION: This system comprises a hot water storage tank, a hot water supply pipe for supplying the hot water of high temperature to the hot water storage tank, a water supply pipe for supplying the water of low temperature to the hot water storage tank, a water supply flow rate sensor mounted on the water supply pipe for measuring a flow rate of the water of low temperature supplied to the hot water storage tank, a water level sensor for measuring a water level of the water of low temperature by a plurality of temperature sensors mounted on the hot water storage tank, a display part for displaying an operation state of the water supply flow rate sensor, and a control part electrically connected with the hot water flow rate sensor and the water level sensor to recognize the measurement data and to display a result on the display part. The water supply flow rate measured by the water supply flow rate sensor and a water supply flow rate estimated on the basis of a measured value of the water level sensor are compared by the control part, and the failure of the water supply flow rate sensor is displayed on the display part when it is judged that the difference between both water supply flow rates is more than a specific value.;COPYRIGHT: (C)2006,JPO&NCIPI
