To provide a chicken house with a heat exchanger in which a filter is hard to be clogged.SOLUTION: A chicken house includes a rectangular floor surface 2, a sidewall 3a being present in a rectangular long side, a gable wall being present in a rectangular short side, a roof for covering up the floor surface 2, multiple heating machines 10 arranged in the longitudinal direction between the sidewalls 3a, and at least one pair of heat exchangers 14 provided at the sidewall 3a across the heating machines 10. The heat exchanger 14 has an outside air outlet 14io for blowing the outside air into a chicken house 1 through a heat exchange element 14a and an inside air suction port 14oi for sucking the inside air in the chicken house 1 in the upper part of the sidewall 3a side, and has an outside air suction port 14ii for sucking the outside air and an inside air exhaust port 14oo for releasing the inside air to the outside of the chicken house 1 through the heat exchange element 14a in the lower part at the side opposite to the sidewall 3a. The chicken house 1 is provided with a projecting plate 15i between the outside air outlet 14io and the inside air suction port 14oi and between the outside air suction port 14ii and the inside air exhaust port 14oo, and a filter 40 in the inside air suction port 14oi. Accordingly, the chicken house constructs a suitable ventilation system in which the heat exchanger 14 is hard to be clogged.SELECTED DRAWING: Figure 2【課題】フィルタの目詰まりしにくい熱交換器を備えた鶏舎を提供する。【解決手段】長方形の床面2と、長方形の長辺にある側壁3aと、長方形の短辺にある妻壁と、床面2を覆う屋根と、側壁3a間の長手方向に配置された複数の暖房機10と、側壁3aに暖房機10を挟んで設けられた少なくとも一対の熱交換器14を備え、熱交換器14は、側壁3a側の上部に外気を熱交換素子14aを介して鶏舎1内に吹き出す外気吹出口14ioと、鶏舎1内の内気を吸い込む内気吸引口14oiと、側壁3aと反対側の下部に、外気を吸い込む外気吸引口14iiと、内気を熱交換素子14aを介して鶏舎1外に放出する内気排出口14ooを有し、外気吹出口14ioと内気吸引口14oiの間及び外気吸引口14iiと内気排出口14ooの間に突出板15iと、内気吸引口14oiにフィルタ40を設けた鶏舎1は、熱交換器14が目詰まりしにくく好適な換気システムを構築する。【選択図】図2
