- Transfers temperature only. Plate exchangers, heat pipes, and run-around coils are sensible devices. They pre-heat or pre-cool the supply air without adding or removing moisture.
- Transfers both temperature and moisture. Enthalpy rotary wheels and some membranes move water vapor, which can cut cooling and dehumidification loads in humid climates.
- Condition Best choice Cold, dry climate Sensible (avoid adding moisture indoors) Hot, humid climate Enthalpy (reduce cooling + dehumidification) Drying / exhaust with moisture Sensible (don't return humidity) Swimming pool / ice rink Enthalpy wheel
- Enthalpy recovery can reduce total HVAC energy by an additional 10–30 % versus sensible-only in humid regions, because it offsets both latent and sensible loads.
- Does enthalpy recovery spread bacteria? Modern enthalpy wheels use antimicrobial coatings and purge sectors; risk is low when maintained per manufacturer guidance. Can a plate exchanger do enthalpy? Only special enthalpy plates or membranes; standard aluminum plates are sensible-only.
시간eat recovery is often described as “sensible” or “enthalpy.” The difference decides comfort, energy savings, and which technology to specify.
