Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional boiler systems heat water to a single temperature range for circulation throughout facilities, which is inefficient and does not cater to varying heating needs across different zones, compromising both fuel efficiency and user comfort.
Innovation Solution
A temperature regulation system that identifies calls for heat from multiple zones and heats the medium to specific temperature ranges tailored to each zone's requirements, using a controller with input and output interfaces to manage temperature settings for zones like rooms, dishwashers, and outdoor areas, ensuring efficient fuel use and user comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the boiler heats water to a single fixed temperature range for circulation throughout the facility, then the system operation is simplified and streamlined, but the system cannot cater to varying heating needs across different zones, compromising fuel efficiency and user comfort
Solution Approach 1:
The patent divides the facility into multiple temperature zones, each with its own temperature sensor and control capability. The boiler system segments its operation into different heating modes (first temperature range for comfort heating, second temperature range for domestic hot water) based on which zone requires heating, allowing customized temperature control for different spatial regions rather than uniform heating throughout the entire facility
Solution Approach 2:
The system dynamically adjusts the heating temperature range based on real-time temperature sensor readings from different zones. The controller selectively activates either the first temperature range (lower, for comfort heating) or the second temperature range (higher, for domestic hot water) depending on which zone calls for heat, making the system adaptable and responsive to varying heating demands rather than operating at a fixed temperature
2Device complexity
If the boiler heats water to a single fixed temperature range, then the control system is simpler, but fuel efficiency deteriorates due to overheating zones that do not require high temperatures
Solution Approach 1:
The patent applies local quality by providing different temperature levels to different zones based on their specific heating requirements. The first zone receives heated water at a first temperature range appropriate for comfort heating, while the second zone receives water at a second temperature range for domestic hot water needs. This localized temperature customization prevents energy waste from delivering excessively hot water to zones that only require mild heating
Solution Approach 2:
The system changes the operating temperature parameter dynamically based on zone requirements. Rather than maintaining a constant high temperature, the boiler adjusts its output temperature between two distinct ranges depending on which zone requires heating. This parameter adjustment optimizes fuel consumption by matching the heating output to the actual thermal needs of each zone
3Productivity
If the boiler heats water to a single fixed temperature range, then the heating process is more efficient in terms of process simplicity, but user comfort deteriorates due to inability to meet diverse temperature requirements
Solution Approach 1:
The facility is segmented into multiple thermal zones with distinct heating requirements. The first zone is served by heated water at a first temperature range optimized for comfort heating, while the second zone receives water at a second temperature range optimized for domestic hot water applications. This segmentation allows the system to simultaneously serve multiple heating needs with appropriate temperature levels for each application
Solution Approach 2:
The boiler system achieves multi-functionality by serving both comfort heating and domestic hot water requirements through a single heating unit. By implementing selective heating to different temperature ranges based on zone demands, the system performs multiple functions (comfort heating and hot water supply) efficiently without requiring separate heating systems for each purpose

AI summary
One embodiment relates to a method for temperature regulation of a medium to be circulated through a plurality of zones of a facility. In this method, a call for heat is received. The method identifies a zone within the plurality of zones from which the call for heat originated. The medium is then heated to a first temperature range if the identified zone is a first zone within the facility and is heated to a second temperature range if the identified zone is a second zone within the facility. The first and second temperature ranges differ from one another. Other methods and systems are also disclosed.
