PROBLEM TO BE SOLVED: To prevent the diffusion of drain water on a drain pan and prevent the drain water from remaining in the drain pan.SOLUTION: A heat exchanger ventilation system comprises: a humidification element installed in a supply air duct through which a supply air flow after being subjected to heat exchange passes and humidifying the supply air flow; a drain pan 24 receiving drain water flowing from the humidification element; and a drain duct discharging the drain water from the drain pan 24 to outside of the system, the drain pan 24 including a bottom surface 81 that includes an exhaust port 244 leading to the drain duct, a pair of pedestals 241, 242 on which the humidification element is mounted, and a drainage 243 having an inclination passing between the paired pedestals 241, 242 and introducing the drain water to the discharge port 244; an outer peripheral wall 82 surrounding a perimeter of the bottom surface 81; and a water reservoir 248 formed outside of each of the paired pedestals 241, 242.SELECTED DRAWING: Figure 3 |
