PURPOSE:To obtain a ceiling embedded type ventilator improved in the maintenance and service therefor by a method wherein a heat exchanger as well as respective fans for air supplying and air discharging are permitted to take them out from the one side surface of the box body of a main body casing. CONSTITUTION:A box type main body casing 5 is provided with a supplying air blow-off port 7 and a discharging air blow-off port 5 on the first side surface 1C1 and is provided with a discharging air suction port 8 and a supplying air suction port 6 on the second side surface 1C2, opposing to the first side surface. A heat exchanger 9 is arranged at the side of the first side surface 1C1 in the main body casing while a fan 12 for supplying air as well as the fan 13 for discharging air are arranged at the side of the second side surface 1C2 along the lengthwise direction of the heat exchanger. A third side surface 1C3, intersecting orthogonally to the first and second side surfaces, is provided with an opening 1d for maintenance and service as well as removable covers 3, 4 for closing the opening 1d while the heat exchanger, the fan for air supplying and the fan for air discharging are permitted to take them out of the opening 1d for maintenance and service. The openings for maintenance and service are gathered on one side surface of the box body, therefore, the provision of the opening of a ceiling plate and an inspection space may be enough by one place while the fans for supplying air and discharging air are constituted so as to be taken out of the main body casing, therefore, maintenance and service may be effected by taking them down from a ceiling to a floor in a room. |
