Solution Overview
Problem
Existing air conditioning control methods in production factories are inefficient in maintaining constant temperature without wasting power, as they require complex data correlations and prior understanding of environmental and operational conditions, making it difficult to adapt to changing factory layouts and operational states.
Innovation Solution
A control device that divides air conditioners into two groups: one operating regardless of facility state and the other adjusting based on facility operational state, using power consumption thresholds to optimize cooling and heating operations, thereby reducing waste and maintaining constant temperature without detailed environmental data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a high-capability air conditioner is used to suppress temperature raise caused by heat radiation, then the temperature control capability is improved, but wasted power consumption increases when the production line stops
Solution Approach 1:
The air conditioners are divided into a first group and a second group. The first group operates regardless of facility state to maintain baseline temperature, while the second group operates based on facility operational state to handle additional cooling demands during heat-generating operations.
Solution Approach 2:
The operational state of air conditioners in the second group is dynamically adjusted based on the operational state of the facility. When the facility operates and generates heat, these air conditioners activate; when the facility stops, they deactivate, preventing wasted energy consumption.
2Use of energy by moving object
If the operational capability of air conditioners is set by changing preset temperature based on environmental data, then wasted power consumption is suppressed, but the system complexity increases due to need for environmental data collection and analysis
Solution Approach 1:
The patent extracts the temperature control function from a single complex system and distributes it across multiple simpler air conditioner units with different operational modes. This eliminates the need for complex environmental data analysis while achieving energy efficiency.
Solution Approach 2:
Each air conditioner in the second group autonomously determines its operational state based on facility operational status without requiring complex centralized control or environmental data processing. The system self-regulates based on simple operational cues.
3Use of energy by moving object
If air conditioners are controlled based on facility operational state, then energy efficiency is improved, but the temperature stability may be compromised when facility state changes frequently
Solution Approach 1:
Air conditioners in the first group operate in advance and continuously to establish baseline temperature conditions before facility operations begin. This preliminary cooling ensures that when the facility starts generating heat, the temperature can be quickly stabilized without fluctuations.
Solution Approach 2:
The first group of air conditioners provides uniform baseline cooling across the facility regardless of operational state, creating a homogeneous temperature foundation that stabilizes the overall environment while the second group provides variable cooling as needed.
