PURPOSE:To obtain a small-shaped ventilating device with heating and cooling functions whose air resistance is small and whose airflow can be enlarged. CONSTITUTION:In the upper and lower fan boxes separated by a partitioning wall 5 once-through fans 8 and 9 whose blades have the same directions and heat exchangers 18 utilizing evaporation and condensation are provided, while on the upper end of the heat exchangers 18 coolers 19 are provided and on the lower end thereof heaters 20 are provided. On the side of a wall 10 vent holes for ventilating-cooling 14a and 14b as well as vent holes for heat collection 15a and 15b are formed, while vent holes 17a and 17b are formed in small-box bodies 16 on the inside of a chamber. Around the fans 8 and 9 front-and-rear surface casings 24a, 24b, 25a and 25b are provided rotatably, while sealing members 32 are supported by support plates 34 and 36 having vent holes for heat collection 33a, 33b, 35a and 35b. In ducts 37a and 37b facing the vent holes 35a, 35b, 15a and 15b vent holes for cool and warm air 39a and 39b as well as dampers 40a and 40b are provided, and vent holes are opened and closed by rotating casings 24a, 24b, 25a and 25b, thereby the blowing directions of the fans 8 and 9 can be shifted. |
