- the specifications of the fan assembly (70) attached to the unit casing (2) need to be compatible with the model of the ventilator (1) being assembled. For this reason, if the fan assembling process and the fan mounting process are performed by different workers, the specifications of the fan assembly (70) to be assembled in the fan assembling process may be incorrect. There is a possibility that the specification of the fan assembly (70) to be attached to the thing (2) is wrong.
- the present embodiment In contrast, in the present embodiment, one worker performs the fan assembling step and the fan mounting step. For this reason, if the operator does not make mistakes in the specifications of the fan assembly (70) to be assembled in the fan assembly process, the specifications of the fan assembly (70) to be attached to the unit casing (2) in the fan installation process are changed. There is no chance of making a mistake. Therefore, according to the present embodiment, it is possible to reduce the risk of attaching a fan assembly (70) having wrong specifications to the ventilation device (1), and in this respect, it is possible to reduce the incidence of defective products. it can.
- the cover (58) of the opening (16) of the left side plate (6) is removed, and the heat exchange element (15) is connected to the guide rail (48).
- the opening (16) along the, maintenance of the air supply blower unit (17) and the like can be easily performed. That is, according to the present embodiment, maintenance of the ventilation device (1) is also facilitated.
- the present invention is useful for a ventilation device.
