Current temperature control systems for outdoor cabinets, particularly those used with 5G devices, face high energy consumption due to continuous operation of air conditioners to maintain temperature, leading to excessive energy waste.
Innovation Solution
A modular temperature control system that adjusts the operation of refrigeration and fan modules based on power consumption and temperature thresholds, dynamically switching between modules to optimize energy use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the number of cabinet door air conditioners and cooling capacity are constantly increased to maintain temperature, then the temperature control reliability is improved, but the energy consumption increases excessively
Solution Approach 1:
The system dynamically adjusts the operational state of air conditioners based on real-time temperature monitoring. When the cabinet temperature is within the normal range, air conditioners are turned off or operated at reduced capacity. When temperature exceeds thresholds, air conditioners are activated or capacity increased. This dynamic adjustment maintains temperature control reliability while avoiding excessive energy consumption from continuous full-capacity operation.
Solution Approach 2:
The system changes operational parameters (number of active air conditioners, cooling capacity, set temperature) based on temperature conditions. Instead of maintaining constant high capacity operation, the system adjusts these parameters dynamically according to actual temperature needs, thereby reducing energy consumption while ensuring temperature control reliability when needed.
2Stability of the object's composition
If air conditioners operate continuously to maintain temperature within normal range, then the temperature stability is improved, but the energy consumption becomes excessive
Solution Approach 1:
Instead of continuous operation, the system employs periodic action by activating air conditioners only when temperature thresholds are exceeded. The system monitors temperature continuously but intervenes only when necessary, creating a periodic on-demand operation pattern that maintains temperature stability when needed while reducing overall energy consumption compared to continuous operation.
Solution Approach 2:
The system allows the cabinet to self-regulate temperature within normal ranges without active cooling intervention. Air conditioners are activated only when the cabinet temperature exceeds the upper threshold, allowing the system to maintain temperature stability through minimal necessary intervention rather than continuous active control, thereby reducing energy consumption.
3Temperature
If the set temperature of air conditioners is constantly lowered to meet dissipation demands, then the cooling effectiveness is improved, but the energy consumption increases
Solution Approach 1:
The system adjusts the set temperature parameter dynamically based on actual cooling needs and environmental conditions. Instead of constantly maintaining a low set temperature, the system raises the set temperature when outdoor conditions permit (e.g., when outdoor temperature is lower than cabinet temperature), thereby reducing the temperature differential and cooling load, which directly reduces energy consumption while maintaining adequate cooling effectiveness.
