Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If active heat management equipment (air conditioning systems) is used to remove heat from data centers, then heat removal effectiveness is improved, but energy consumption increases
Solution Approach 1:
The patent converts the harmful waste heat generated by servers into a beneficial resource by using it to drive absorption chillers. The waste heat from server racks provides the thermal energy needed to power the cooling system, transforming an adverse factor (heat waste) into a useful resource that reduces the need for additional energy-consuming cooling equipment.
Solution Approach 2:
The data center cooling system serves itself by using the heat generated within the data center to power the absorption chiller that cools the data center. The system is self-sustaining, where the waste heat from computing operations directly drives the cooling process, eliminating the need for external energy input to the cooling system.
2Temperature
If active heat management equipment is used, then heat removal capability is improved, but heat management equipment generates additional heat
Solution Approach 1:
The patent addresses this contradiction by capturing the additional heat generated by active cooling equipment and using it to supplement the waste heat from servers. This combined heat source powers the absorption chiller, converting the harmful additional heat into a useful resource that enhances the overall heat removal capability without increasing net energy consumption.
3Stability of the object's composition
If conventional HVAC systems with thermostats are used, then temperature control is maintained, but energy efficiency deteriorates
Solution Approach 1:
The patent replaces the conventional mechanical vapor-compression cooling system with a thermally-driven absorption chiller system. This substitution eliminates the need for high-power electric compressors and refrigerant circulation pumps, using instead thermal energy from waste heat to drive the cooling process, thereby significantly improving energy efficiency while maintaining temperature control.

AI summary
New data center heat removal systems and methods allow a combination of active and passive thermal processes for removing heat from and cooling air in data center environments. Systems and methods include a data center heat removal system including an adjustable thermal feed cold air intake system, a distribution system for cold and warm air including one or more hot aisles and one or more cold aisles, and a convection system to draw cool air through data center equipment using a naturally- occurring convection processes to expel hot air. Misters, cooling elements, and/or freezer boxes may further cool the intake of air. A controller is programmed to efficiently manage and control the climate (e.g., temperature, humidity, air flow, pressure, air quality, etc.) within a data center to minimize the use for energy for air distribution and cooling.
