Abstract

Provides good practice to limit the internal air leakage in bidirectional air handling units, especially those fitted with a rotary heat exchanger. Outlines the most important measures to be considered in the design and setting of a unit to minimise the leakage. Recommendations also present guidelines on how to correct the declared performance due to leakages. The potential magnitude of internal leakage rates resulting from incorrect unit design and the corresponding consequences are also covered.
