Description

  The present invention relates to a clean room in which heat treatment and cleaning treatment of indoor air can be appropriately performed by a heat exchange device (FCU) and an air cleaning device (FFU).

  Conventionally, a heat exchange device (FCU (Fan Coil Unit)) that sucks indoor air and processes air-conditioning load and blows the air that has been blown into the room by sucking the air blown from the heat exchanger. There is a clean room in which an air purifier (FFU (Fan Filter Unit)) to be placed is arranged in the upper part of the room. In this clean room, air that has been heat-treated by the heat exchange device is cleaned and blown by the air purifier, and air that has been blown by the air cleaner and convected in the room is sucked and processed by the heat exchanger and circulated in the room. In this conventional clean room, it is possible to reduce the operation cost without generating a useless air volume. Further, since both the heat exchange device and the air cleaning device are arranged in the same room and the air is moved by the air current, a duct is not required, and the space can be used effectively. Moreover, the construction cost concerning a duct construction can be reduced and a construction period can be shortened (for example, refer patent document 1).
