Free Cooling System Water Flow Detection for Reserve Tank Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional free cooling systems for computing centers face high costs and maintenance burdens due to the need for large water reserves, which require cooling and disinfection, and inefficient water usage patterns.
Innovation Solution
A method and apparatus for a conditioning system that detects water flow and level to optimize water consumption by prioritizing fan operation and auxiliary cooling when water is scarce, using water only when necessary to maintain setpoint temperatures, and reducing tank size through intelligent control and management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If large water reserves are stored in tanks for free cooling systems, then cooling capacity is ensured during water service interruptions, but tank maintenance costs and operational complexity increase significantly
Solution Approach 1:
The invention extracts the water storage function from the free cooling system by using the condenser water tank of the air conditioning system for dual purposes: both as a heat exchange medium and as a water reserve for evaporative cooling, eliminating the need for separate dedicated storage tanks
Solution Approach 2:
The condenser water tank is designed to serve multiple functions simultaneously: condenser heat exchange, water reserve for evaporative cooling, and cooling reservoir, thereby reducing overall system complexity and eliminating dedicated storage infrastructure
2Temperature
If water is continuously used for evaporative cooling in free cooling systems, then cooling effectiveness is maintained, but water consumption and associated costs increase
Solution Approach 1:
The system incorporates sensors that continuously monitor water level, temperature, and flow conditions, with a control unit that automatically adjusts evaporative cooling operation based on real-time data, enabling water usage only when and where needed
Solution Approach 2:
The system dynamically switches between different cooling modes (evaporative cooling, conventional cooling, hybrid operation) based on ambient conditions, water availability, and thermal load requirements, optimizing water consumption while maintaining cooling effectiveness
3Quantity of substance
If dedicated water storage tanks are installed for free cooling systems, then water availability is ensured, but initial installation costs and space requirements increase
Solution Approach 1:
The invention merges the water storage function with the existing condenser water tank of the air conditioning system, combining two separate functions (heat exchange and water storage) into a single integrated component, thereby eliminating the need for additional dedicated storage tanks
