2Loss of energy

If air volume is regulated according to actual workload, then energy saving is improved, but control complexity increases

Engineering Contradiction:
Improveenergy savingVSAvoidcontrol system complexity
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The patent employs a feedback control mechanism where temperature sensors monitor the actual temperature at cabinet outlets, compare it with preset temperature values, and use the temperature difference to adjust the opening degree of air valves. This closed-loop feedback system enables automatic adaptive regulation without requiring complex manual control.

Inventive Principle:
