Solution Overview
Problem
Current air conditioning systems fail to optimize energy efficiency due to inherent thermal losses and inertia, leading to increased energy consumption and non-uniform temperature distribution within indoor environments, which cannot be effectively compensated for in real-time.
Innovation Solution
A method that involves setting a comfort temperature, monitoring its trend, and using an air conditioning device to activate/deactivate based on predetermined durations, calculating surface areas of temperature curves to balance thermal energy, and adjusting thermal power to maintain a constant energy content, minimizing thermal losses and ensuring comfort across the environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional air conditioning systems regulate temperature based on a single reference value, then the control system is simple, but thermal losses cannot be compensated in real-time and energy efficiency is not optimized
Solution Approach 1:
The patent divides the indoor environment into multiple zones with different reference temperatures (first zone with temperature T1, second zone with temperature T2). This segmentation allows independent temperature control for each zone, enabling real-time compensation of thermal losses in different areas without requiring a completely complex centralized system.
Solution Approach 2:
The system pre-calculates and stores reference temperatures for different zones before operation. These reference temperatures are determined based on expected thermal conditions and loss patterns. By having these references prepared in advance, the system can quickly respond to thermal losses without complex real-time calculations, balancing energy efficiency with control simplicity.
2Stability of the object's composition
If the system uses a single reference temperature for the entire environment, then the control is simple, but uniform temperature distribution cannot be achieved
Solution Approach 1:
The patent divides the indoor environment into multiple zones with different reference temperatures (first zone with temperature T1, second zone with temperature T2). This segmentation allows independent temperature control for each zone, enabling real-time compensation of thermal losses in different areas without requiring a completely complex centralized system.
Solution Approach 2:
Each zone is assigned a specific reference temperature tailored to its local thermal characteristics and loss patterns. The first zone has reference temperature T1 while the second zone has reference temperature T2, allowing each area to maintain optimal temperature independently. This local customization achieves uniform temperature distribution across the entire environment while keeping individual zone controls relatively simple.
3Temperature
If the air conditioning device operates continuously to maintain constant temperature, then temperature stability is achieved, but energy consumption increases
Solution Approach 1:
The patent implements periodic measurement and adjustment cycles rather than continuous operation. The control unit measures actual temperatures, compares them with reference temperatures, and activates the air conditioning device only when deviations are detected. This periodic action maintains temperature stability while avoiding unnecessary continuous operation, thereby reducing energy consumption.
Solution Approach 2:
The system continuously monitors actual temperatures in each zone and compares them against reference temperatures. When deviations are detected, the control unit activates the air conditioning device to correct the temperature. This feedback mechanism ensures temperature stability is maintained only when needed, preventing unnecessary energy consumption during periods when temperature is already within acceptable ranges.
