In the figure, the main body 6 includes an exhaust passage 1 for discharging indoor air 2, an air supply passage 3 for supplying outdoor air 4, a heat exchanger 5 for exchanging heat between the exhaust air and the supply air, and A heat exchanger 5 and a blower 7 for exhaust and air supply are incorporated, and a supply and exhaust duct 10 is connected to the main body 6 in an attic space 9. A cold/hot water coil piping 12 is wound around the outdoor air supply duct connecting portion 11 of the main body 6. In the figure, 8 is a ceiling plate that partitions the attic space 9 and the room, and 13 is a heat insulating material.
