Solution Overview
Problem
Conventional data center air cooling systems consume significant energy and struggle to efficiently manage thermal conditions across multiple rooms with varying temperature requirements, especially when some rooms use liquid cooling solutions.
Innovation Solution
A data center air cooling system that utilizes a combination of air ducts, air chambers, and louvers to adjust air inlet temperature and airflow in each room based on specific thermal needs, allowing for serial or parallel airflow modes between rooms, and using fans to manage airflow effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a conventional air cooling system is used to cool all rooms, then the thermal environment is maintained, but energy consumption is significant and cannot accommodate varying temperature requirements of different rooms
Solution Approach 1:
The data center is divided into multiple IT rooms with different thermal requirements. Each room can be independently controlled through adjustable air inlet louvers, allowing customized cooling strategies for each segment rather than uniform cooling across the entire facility.
Solution Approach 2:
The system employs dynamically adjustable air inlet louvers in each room that can be controlled independently. These louvers can be opened or closed to different degrees based on real-time thermal conditions and cooling demands, enabling adaptive temperature control that optimizes energy consumption.
2Adaptability or versatility
If air cooling is provided to all rooms uniformly, then cooling is provided, but rooms with liquid cooling solutions receive excessive cooling
Solution Approach 1:
Different cooling strategies are applied to different rooms based on their specific cooling methods. Rooms with liquid cooling solutions have their air inlet louvers adjusted to receive warmer air or reduced airflow, while rooms with air cooling receive adequate cold air supply. This localized customization prevents energy waste in liquid-cooled rooms.
Solution Approach 2:
The system changes the air inlet temperature parameter for different rooms by adjusting louver positions. Rooms with liquid cooling receive air at higher temperatures, while rooms with air cooling receive air at lower temperatures, optimizing the cooling efficiency for each room's specific cooling methodology.
3Temperature
If multiple independent cooling systems are used for each room, then specific temperature requirements are met, but system complexity increases
Solution Approach 1:
A single centralized cooling system serves multiple IT rooms with different thermal requirements. The system achieves room-specific temperature control not through multiple independent cooling units, but through a universal cooling infrastructure equipped with adjustable air inlet louvers in each room that can be controlled independently.
Solution Approach 2:
Adjustable air inlet louvers act as intermediary devices between the centralized cooling system and individual IT rooms. These louvers mediate the airflow and temperature delivery, enabling each room to receive customized cooling conditions from a single cooling source without requiring multiple independent systems.
