PROBLEM TO BE SOLVED: To solve problems in which adjustment is difficult in a tunnel type ventilation in order to finely manage ventilation and temperature management every age in day and it cannot be satisfied from the viewpoint of energy saving, in the breeding of a broiler where an environment of a period of a short age in day has a great effect on a body weight when being grown.SOLUTION: A poultry house is characterized by including a rectangular floor, sidewalls provided at rectangular long sides, gable walls provided at rectangular short sides, a roof for covering the floor, multiple heating machines disposed in the longitudinal direction between the sidewalls, and at least one pair of heat exchangers provided across the heating machines at the sidewalls. The heat exchanger has an outside air outlet having a box shape and blowing the outside air into the poultry house through heat transfer elements in the upper part of the sidewall side, an inside air suction port for sucking the inside air in the poultry house in the lower part of the sidewall side, an outside air suction port for sucking the outside air at the side opposite to the sidewall, and an inside air discharge port for discharging the inside air to the outside of the poultry house through the heat transfer elements.SELECTED DRAWING: Figure 1
