Heating Device Night Mode Parameter Control to Reduce Noise
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional heating devices that burn propane or butane generate significant noise, particularly disturbing during quiet times, and existing solutions like reducing blower power or using night modes do not adequately address noise reduction, especially in confined spaces like caravans or boats where continuous heating is desired.
Innovation Solution
A heating device with a burner, combustion air blower, circulating air blower, control device, and data storage device that operates in a night mode by adjusting parameters such as temperature tolerance, power levels, and fan speeds to minimize noise, prioritizing air heating over fluid heating to reduce the frequency of fuel valve openings and maintain quieter operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the heating device operates at standard power levels to maintain heating performance, then heating efficiency is improved, but noise level increases
Solution Approach 1:
The control device dynamically adjusts operating parameters based on time of day and heating requirements. During night mode, the system selectively operates only the air heating function at reduced power levels, while disabling or reducing fluid heating operations. This dynamic parameter adjustment allows the system to maintain adequate heating performance while significantly reducing noise-generating operations during nighttime hours.
Solution Approach 2:
The system changes operational parameters by implementing different parameter sets for night mode versus standard mode. Night mode parameters include reduced fan speeds, lower burner power levels, and relaxed temperature tolerance ranges. These parameter changes enable the heating device to operate quietly during nighttime while still providing sufficient heating, resolving the contradiction between heating efficiency and noise level.
2Measurement precision
If the temperature control range is narrowed to maintain precise temperature, then temperature control precision is improved, but the frequency of burner operations increases causing more noise
Solution Approach 1:
During night mode, the system applies partial action by deliberately allowing larger temperature deviations from the setpoint rather than maintaining tight temperature control. The control device is configured to tolerate temperature ranges that would be unacceptable in standard mode. This partial relaxation of temperature precision requirements significantly reduces the frequency of burner cycling and fan operations, thereby reducing noise while still providing acceptable heating performance during nighttime hours.
3Reliability
If the heating device operates continuously to maintain temperature, then heating reliability is improved, but noise level increases during quiet periods
Solution Approach 1:
The system implements periodic action by switching between different operational modes based on time of day. During night mode, the heating device operates intermittently with extended intervals between heating cycles, utilizing relaxed temperature tolerance ranges to delay the next heating cycle. This periodic operation pattern maintains heating reliability over 24-hour periods while significantly reducing noise during nighttime quiet periods, as the system does not require continuous operation.

AI summary
The invention relates to a heating device (1). A combustion air blower (3) supplies combustion air to a burner (2). The burner (2) burns a gas/air mixture of the combustion air and a fuel and is intended for heating air. A circulation blower (5) discharges heated air from the heating device (1). A control apparatus (7) acts on at least one component (2, 3, 3', 5, 12) of the heating device (1), with a night mode parameter set, which is assigned to an operation of the heating device (1) in a night mode, and a standard parameter set being stored in a data storage device (8). The control apparatus (7) accesses the night mode parameter set after activation of the night mode and uses same for acting on the component (2, 3, 3', 5, 12). The night mode parameter set causes a reduction in background noise generated by the heating device (1).
