Heat recovery is often described as \u201csensible\u201d or \u201centhalpy.\u201d The difference decides comfort, energy savings, and which technology to specify.<\/p>\n
Transfers temperature only<\/strong>. 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.<\/p>\n Transfers both temperature and moisture<\/strong>. Enthalpy rotary wheels and some membranes move water vapor, which can cut cooling and dehumidification loads in humid climates.<\/p>\n Enthalpy recovery can reduce total HVAC energy by an additional 10\u201330 % versus sensible-only in humid regions, because it offsets both latent and sensible loads.<\/p>\n Does enthalpy recovery spread bacteria?<\/strong> Can a plate exchanger do enthalpy?<\/strong>Enthalpy Recovery<\/h2>\n

\nModern enthalpy wheels use antimicrobial coatings and purge sectors; risk is low when maintained per manufacturer guidance.<\/p>\n
\nOnly special enthalpy plates or membranes; standard aluminum plates are sensible-only.<\/p>\n
