Description: In swine confinement buildings, winter ventilation heat loss is large relative to other thermal losses. A heat exchanger can be utilized to significantly reduce these losses by warming incoming ventilation air by means of heat recovered from the exhaust air. In many cases, the supplemental energy recovery required to achieve a heat balance is a small part of the total energy exchange, and a heat ex changer of low effectiveness is both practical and possible for such applications. The desired attributes for this heat ex changer were modular design, low cost, durability, and ease of cleaning. A modular design avoids the need to redesign for different building sizes, and provides greater flexibility to incorporate heat exchangers in ventilation systems of various types. An important design objective is to minimize the power consumption of the fans relative to the heat transferred. Problems found with livestock barn heat exchangers (Larkin and Turnbull 1977) are freezing of condensate in the exhaust stream during cold weather, and fouling with dust. The icing and dust problems must be solved, preferably by an automatic system requiring minimum super vision.
