Solution Overview
Problem
Traditional chilled water data center cooling systems have high energy consumption due to numerous heat exchange links and a one-way working medium, leading to poor energy performance.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If traditional chilled water cooling system is used, then cooling function is provided, but energy consumption is high due to large numbers of heat exchange links
Solution Approach 1:
The patent combines multiple heat exchange functions into a single evaporative condenser that handles both condensation and evaporative cooling in one integrated device, eliminating the need for separate heat exchange links and reducing energy consumption
Solution Approach 2:
The evaporative condenser performs multiple functions simultaneously: it condenses refrigerant gas, cools the condensing refrigerant through evaporative cooling, and provides overall heat exchange functionality, making the system more efficient with fewer components
2Loss of energy
If traditional one-way working medium system is used, then cooling is provided, but overall energy performance is poor
Solution Approach 1:
The patent implements a dynamic two-way working medium circulation system where the refrigerant can flow in different directions based on operating conditions, allowing the system to adapt to varying cooling loads and improve overall energy performance
Solution Approach 2:
The circulating pump ensures continuous circulation of the working medium through the optimized circulation path, maintaining continuous heat exchange and cooling action without interruption, which improves energy efficiency
