Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional thermal regulation methods for buildings, such as 'TOR' and 'PID' types, face issues of imprecision, excessive stress on equipment, high energy consumption, and rapid wear, failing to provide optimal thermal comfort and efficiency in multi-zone environments.
Innovation Solution
A multi-zone thermal regulation method that applies a setpoint temperature to each room, calculates temperature differentials, determines heat requirements based on these differentials, and adjusts the air production unit's load rate to optimize energy consumption and comfort, including temporary disconnection of rooms at set temperature and reconnection based on temperature thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If TOR (on/off) thermal regulation is used, then the system is simple and inexpensive to implement, but it causes excessive stress on equipment, high energy consumption, and rapid wear
Solution Approach 1:
The patent implements dynamic control of the air production unit by continuously adjusting its operation based on real-time temperature differentials and heating requirements. Instead of static on/off control, the system dynamically modulates the air production unit's output to match the actual thermal needs of each zone, thereby reducing stress cycles and extending equipment life while maintaining simplicity
2Device complexity
If TOR (on/off) thermal regulation is used, then the control system is simple, but it results in high energy consumption and imprecise temperature control
Solution Approach 1:
The patent employs feedback control mechanisms where temperature sensors continuously monitor each zone's actual temperature, calculate the differential from the setpoint, and feed this information back to the control system. This feedback loop enables precise energy management by adjusting the air production unit's operation based on actual thermal needs rather than binary on/off states, reducing energy waste while keeping the control system relatively simple
3Adaptability or versatility
If independent multi-zone thermal regulation is implemented, then each room can be controlled independently for optimal comfort, but the system complexity and cost increase
Solution Approach 1:
The patent divides the building into multiple independent thermal zones, each with its own temperature sensor and control parameters. This segmentation allows each zone to be regulated independently based on its specific heating requirements and occupancy patterns, providing customized thermal comfort without requiring a completely separate air production unit for each zone, thus managing complexity through modular zoning
4Duration of action of stationary object
If modulating control is used to extend equipment lifespan, then the air production unit operates more gently, but the system becomes more expensive
Solution Approach 1:
The patent implements dynamic modulation of the air production unit's operation based on real-time heating requirements calculated from temperature differentials. This dynamic control allows the system to operate the equipment more gently by matching output to actual demand rather than using aggressive on/off cycles, thereby extending equipment lifespan. The control approach uses straightforward calculations and control logic to achieve this dynamic operation without requiring complex or expensive control systems

AI summary
The invention relates to a method for the multizonal hot and/or cold thermal regulation of a building (1). According to the invention, the method includes in particular a step of determining a calorific need Ct of the building (1) at a time t, the calorific need Ct of the building (1) being determined depending on a differential ΔTm of each regulated room (P1, P2, P3, P4). The differential ΔTm of a regulated room (P1, P2, P3, P4) corresponds to the differential between a temperature Tm measured at a time t and the setpoint temperature Tc of each regulated room (P1, P2, P3, P4) of the building (1). Thus, according to the invention, the method comprises a step of adjusting the level of demand of the air production unit (4) for the building (1) at least depending on the calorific need Ct.
