Description: The use of heat exchangers to reduce the winter ventilation heat loss in livestock confinement buildings was reported as early as 1950 (Giese and Downing 1950). Despite this option livestock producers have traditionally chosen to add supple mental heat to their animal enclosures, rather than use a heat recovery system. Problems that discourage the use of heat exchangers in livestock buildings are freezing of condensate on the heat transfer surfaces, and fouling with dust produced by the animals and the feeds. The air-to-air, cross-flow shell-and-tube heat exchanger (Fig. 1) described by McGinnis et al. (1983) and McGinnis (1981) largely overcomes these problems and is a suitable heat exchanger choice for many building ventilation heat recovery applications, particularly in livestock confinement buildings. In the design of heat exchangers of this type, the engineer must rely to a great extent upon experience and judgement to estimate the performance characteristics of a given design under specified operating conditions.
