- You need high sensible efficiency with low maintenance. The air streams are close together. Cross-contamination must be minimized. The application is drying, data center cooling, or general ventilation.
- You need both heat and humidity recovery. Airflow is large and centralized. Installation space allows a round wheel housing.
- The supply and exhaust ducts are separated. Zero cross-contamination is required. The environment is dusty, corrosive, or explosive.
- Mine ventilation: Heat pipe or plate Data centers: Plate (sensible, no moisture transfer) Swimming pools / ice rinks: Enthalpy rotary wheel Industrial drying: Plate (sensible, no moisture return) Kitchen / lab exhaust: Run-around coil or heat pipe
- Which technology is most reliable? All three are reliable when correctly applied. Plate exchangers generally have the lowest maintenance and longest life. Can I combine technologies? Yes. For example, a plate exchanger can be used for primary recovery and a heat pipe for a remote exhaust point.
기음hoosing the right air-to-air heat exchanger depends on airflow, temperature, humidity, installation space, and contamination risk. This guide compares the three most common technologies.
