Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional data center cooling systems face challenges with high energy consumption, increased cooling demands, and inefficient use of resources due to the need for separate installations and high capital and operational costs, especially in modern high-density data centers where initial cooling capacity requirements are low compared to peak demands.
Innovation Solution
A modular chiller system that includes a switching and pumping module, drycooler modules, and chiller modules sharing common water, power, and signal interfaces, allowing for scalable cooling capacity adjustments by adding modules without additional infrastructure, and operating in economizer-only, mixed, or full mechanical modes to optimize energy use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If cooling capacity is increased to meet high power density equipment demands, then equipment can operate at desired temperature, but capital expenditure and operational costs increase
Solution Approach 1:
The system dynamically switches between economizer mode (using ambient air when cool) and mechanical chiller mode (when ambient temperature is high), optimizing energy consumption based on real-time conditions. This dynamic operation resolves the contradiction by adapting cooling capacity to actual needs rather than providing constant maximum cooling.
Solution Approach 2:
The system changes operational parameters by switching between different cooling modes (economizer vs. mechanical) based on ambient temperature conditions, allowing optimal energy efficiency across varying environmental conditions while maintaining equipment temperature requirements.
2Temperature
If cooling capacity is increased to meet high power density equipment demands, then equipment can operate at desired temperature, but capital expenditure on cooling equipment increases
Solution Approach 1:
The cooling system is segmented into separate economizer modules and chiller modules that can be independently sized and configured. This allows the system to be scaled to match actual cooling needs rather than provisioning for maximum possible load, reducing capital expenditure while maintaining adequate cooling capacity.
Solution Approach 2:
The system provides multiple functions through a single integrated platform that can operate in economizer mode, mechanical chiller mode, or hybrid mode. This multi-functionality eliminates the need for separate cooling systems for different operating conditions, reducing overall capital expenditure.
3Adaptability or versatility
If modular design is implemented to improve scalability, then cooling capacity can be increased by adding modules without additional infrastructure, but device complexity increases
Solution Approach 1:
The system is divided into standardized, interchangeable modules (economizer modules and chiller modules) with uniform connection interfaces. This segmentation enables scalable configuration where modules can be added or removed without affecting the overall system architecture, managing complexity through standardization.
Solution Approach 2:
All modules share universal water, power, and signal interfaces, creating a standardized platform that simplifies integration. This universality reduces the complexity that would otherwise arise from custom interfaces for each module type, allowing straightforward scaling.
4Power
If traditional centralized cooling systems are used, then cooling capacity can be provided, but installation complexity and redundancy management become difficult
Solution Approach 1:
The centralized cooling system is replaced with distributed modular units that can be independently installed and managed. Each module is self-contained with standardized interfaces, simplifying installation compared to traditional centralized systems while maintaining adequate cooling capacity through aggregation of multiple units.
Solution Approach 2:
The system architecture changes from centralized to distributed modular configuration, fundamentally altering installation and redundancy management approaches. Individual modules can be independently installed, tested, and commissioned, reducing overall installation complexity while providing natural redundancy through modular replication.

AI summary
A modular chiller system includes a switching and pumping module, one or more drycooler modules, and one or more chiller modules. The switching and pumping module, the one or more drycooler modules, and the one or more chiller modules share same water, power, and signal interfaces. The cooling capacity of the modular chiller system may be increased by adding drycooler modules or chiller modules without additional hydraulic and electrical infrastructures.
