Laminar counterflow duct recuperator: the ideal heat exchanger?

Author(s) : VELTKAMP W. B.

Type of article: Article

Summary

The author presents a recuperator, in which all ducts are surrounded by ducts in which the flow is reversed. It can achieve a high degree of effectiveness at low levels of pressure loss. The duct geometry also allows the use of materials that conduct heat poorly. This makes it possible to construct gas-gas recuperators from plastic, which is less expensive than the metal cross-flow recuperators currently used. The recuperator is not only suitable for heat recovery from ventilation air; it can also be used in central heating boilers, dryers and in recuperative radiant burners.
