Abstract
A ventilation heat recovery system is mounted in a livestock building or the like. The system includes a counterflow shell and tube heat exchanger with an outer sleeve axially surrounding the shell along a substantial longitudinal portion thereof. Air is drawn from the ambient atmosphere into the shell for heat-exchanging flow counter to exhaust air that is drawn from the building atmosphere and forced through the exchanger tubes for exhausting to the ambient atmosphere. An annular-shaped distribution channel is formed between the outer sleeve and the shell, and the sleeve has a plurality of distribution orifices therealong for distributing incoming air to the building atmosphere. The channel is in flow communication with the shell through a transition zone defined between the end of the shell and a transition manifold which supports the tubes. Alternatively, the shell is in flow communication with a remote distribution duct having a plurality of distribution orifices.
