Solution Overview
Problem
Existing hot water installations require continuous water circulation or timer-based pump control to maintain desired water temperature, leading to inefficiencies and unnecessary energy consumption.
Innovation Solution
A flow detection device is installed on the cold water branch to initiate and stop hot water circulation based on water consumption, eliminating temperature and time-dependent activations and using a control switch activated by water flow to manage the heating device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If continuous water circulation or timer-based pump control is used to maintain desired water temperature, then the water temperature stability is improved, but the energy consumption increases
Solution Approach 1:
The patent implements periodic action by using a flow detection device that triggers pump operation only when water consumption is detected. The control switch activates the circulation pump periodically based on actual demand signals from the flow detector, rather than maintaining continuous operation. This ensures temperature stability is maintained during periods when hot water is actually being used, while eliminating unnecessary energy consumption during periods of no usage.
2Use of energy by moving object
If flow detection device is installed on cold water branch to initiate hot water circulation, then the energy consumption is reduced, but the device complexity increases
Solution Approach 1:
The patent uses an intermediary approach by installing the flow detection device on the cold water branch rather than directly in the hot water circulation system. This intermediary location allows the system to detect water consumption events indirectly through the cold water supply line, triggering the hot water circulation pump only when needed. This reduces complexity compared to installing sensors throughout the hot water system, while still achieving energy savings through demand-based control.
3Ease of operation
If timer-based pump control is used, then the system operation is simplified, but the water delivery time increases
Solution Approach 1:
The patent implements feedback control by using a flow detection device that provides real-time information about water consumption to the control system. When the detector senses water flow indicating a tap is open, it immediately triggers the circulation pump to deliver hot water. This feedback mechanism eliminates the delays inherent in timer-based systems, providing rapid hot water delivery while maintaining operational simplicity through automatic demand-responsive control.
