Combi Boiler Start-Stop Control to Reduce Chimney Heat Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current combi boilers operate with a continuous water circulating pump, leading to excessive heat loss as they maintain water temperatures significantly higher than the environment, even in summer, resulting in unnecessary energy consumption and increased heat loss through chimneys.
Innovation Solution
The development of a main card with enhanced software that measures atmospheric temperature to control the combi boiler's heating function, starting and stopping the water pump based on external temperature, thereby reducing heat loss and optimizing energy usage by only generating heat when required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the combi boiler operates continuously with the water circulating pump running, then the heating system maintains stable temperature, but excessive heat loss occurs through chimneys and installations
Solution Approach 1:
The patent implements periodic operation of the combi boiler and water circulating pump based on atmospheric temperature measurements. The system alternates between active heating periods and idle periods, using a start-stop control mechanism that activates the boiler only when external temperature falls below a predetermined threshold, thereby eliminating continuous operation and reducing thermal losses through chimneys and installation pipes
Solution Approach 2:
The patent employs atmospheric temperature sensors that continuously monitor external conditions and provide feedback to the control unit. This feedback mechanism enables the system to automatically adjust its operation state (on/off) based on real-time temperature data, ensuring the boiler operates only when heating is actually required, thus preventing energy waste while maintaining temperature stability when needed
2Temperature
If the combi boiler heats water to high temperatures (40-50 degrees or above), then the heating system can effectively warm the environment, but heat loss in chimneys increases
Solution Approach 1:
The patent implements dynamic temperature control by adjusting the boiler's operating temperature based on atmospheric conditions. Rather than maintaining a fixed high temperature, the system dynamically modulates water temperature and operation duration according to external temperature measurements, heating water to the minimum necessary temperature and for the minimum necessary time, thereby reducing thermal losses in chimneys while still achieving effective environmental warming
3Productivity
If the water circulating pump operates continuously, then heat is continuously distributed through radiators, but heat is absorbed by installations and external column lines
Solution Approach 1:
The patent applies periodic operation to the water circulating pump, synchronizing its operation with the boiler's heating cycles. The pump runs only during active heating periods when the boiler is operating, and remains stopped during idle periods, thereby eliminating continuous circulation that causes heat absorption by installations and external column lines, while still ensuring adequate heat distribution during heating phases
Solution Approach 2:
The patent ensures continuous useful action during heating phases by maintaining synchronized operation of the boiler and water circulating pump. When the boiler is active, the pump continuously circulates heated water through the radiators, ensuring uninterrupted heat distribution. This coordinated continuous operation during active phases maximizes heating efficiency while minimizing losses during idle phases when both systems are stopped
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution significantly reduces heat loss and energy consumption by operating the combi boiler in a start-stop mode, minimizing chimney heat loss and enhancing efficiency, especially during climatic transition phases, by calculating the necessary thermal energy based on external temperatures and adjusting the operation accordingly.
Implementation Method 1
a sensor measuring the atmospheric temperature (3); the operation system of software in the main card (2) continuously measures the atmospheric temperature with the sensor (3)
Implementation Method 2
the combi boiler heats the water within the system... the combi boiler fulfills its heating function by taking its electricity... and heats the water up to the measuring range
Implementation Method 3
continuous water circulating pump motor (carrying modulation feature on water pump combi, working principle is the same) makes the water in radiators pass over the combi boiler
Implementation Method 4
makes the water in radiators pass over the combi boiler by absorbing it... the heat is absorbed much better by the return water in the combustion chamber
Implementation Method 5
the energy in the hot water heated by the combi boiler is absorbed by the block and transmitted to the exterior surface of the building and to the atmosphere
