데이터센터의 열회수: 공기 대 공기 열교환기 냉각

Data centers consume enormous amounts of electricity for cooling. Much of that energy leaves the facility as low-grade waste heat. By using air-to-air heat exchangers, facilities can pre-cool incoming ventilation air with exhaust air, reducing the load on mechanical cooling and improving Power Usage Effectiveness (PUE).

Why Data Center Heat Recovery Makes Sense

• Server racks produce a steady, high-temperature exhaust airflow.
• Outside air must often be cooled before entering the white space.
• Plate or heat-pipe exchangers transfer heat with no cross-contamination.
• Recovered heat can pre-heat offices, domestic hot water, or adsorption chillers.

Plate Exchangers vs Rotary Wheels for Data Centers

요인	Plate Exchanger	Rotary Wheel
Cross-contamination risk	Very low	Low with purge sector
Moisture transfer	현열만	Enthalpy possible
효율	70–85 %	75–85 %
유지보수	Low	중간
최적 fit	Cool/dry climates	Humid climates

Implementation Considerations

• Match exchanger capacity to IT load and airflow (CFM or m³/h).
• Design for N+1 redundancy if cooling is critical.
• Integrate with the building management system for variable-speed fan control.
• Include filtration upstream of the heat exchanger to protect fins and plates.

Heat recovery works best when combined with free-cooling and airflow management. In cold or temperate climates an air-side economizer can satisfy the load directly for many hours, with the exchanger handling the remainder and trimming compressor runtime. Hot-aisle or cold-aisle containment keeps the recovered airstream at a stable temperature so effectiveness stays near the rated point. Monitor the loop through the building management system and report recovery against Power Usage Effectiveness so savings are visible to operations. Filtration upstream of the core remains essential: fine dust in return air will otherwise coat plates or heat pipes and raise pressure drop.

자주 묻는 질문

Does heat recovery affect cooling redundancy?
No, if the system is designed as a pre-cooling stage. Chillers or CRAC units remain as backup.

Can recovered heat be reused?
Yes. It can pre-heat make-up air, domestic water, or drive absorption cooling, depending on temperature level.
