- Air-to-air heat recovery is applied across very different buildings, and the "best" exchanger depends on what each building values most: air purity, uptime, moisture control, or simply first cost. Below are three common sectors and the logic that drives their choice.
- Air quality is non-negotiable. Fresh-air volumes are huge and infection control forbids stream mixing, so plate (fixed-plate) exchangers dominate. See our dedicated hospital heat recovery guide.
- Here the priority is continuous, reliable cooling with the lowest possible PUE. Sensible plate recovery and air-to-water loops feed the cooling plant; see the broader data-center heat recovery overview.
- Process and exhaust air carry both heat and moisture, often with grease or particulates. Enthalpic recovery plus robust cleanability wins. Our food-processing heat recovery guide covers it.
- Must streams stay separate? - Plate. Max effectiveness at huge airflow? - Rotary wheel. Humid climate or moist exhaust? - Enthalpic / desiccant. Ducts far apart? - Run-around coil. For climate-specific nuance, read selection by climate, and validate any choice with an AHU selection calculation.
