5. An automatic warehouse for a clean room having an upper ceiling, a ceiling of at least one lower floor, a floor of at least one upper floor, a bottom floor, walls and an entrance on each floor, the automatic warehouse comprising:
-
vertical racks for supporting articles extending from a location approximate the bottom floor to a location proximate the upper ceiling, the racks are positioned to define a loading space in between two racks and positioned to define a clean air path between each rear face of the racks and the opposing wall of the automatic warehouse;
an air intake port provided in the vicinity of the upper ceiling for intaking air from an upper clean fan unit in the upper ceiling into the automatic warehouse;
the upper clean fan unit for blowing air from the upper ceiling to the floor of the at least one upper floor;
a middle clean fan unit in the ceiling of the at least one lower floor for sucking air through the floor of the at least one upper floor and blowing the air sucked through the floor of the at least one upper floor to the bottom floor;
an air supply means provided at a bottom portion of each rack for sucking air into the loading space from the clean air path and discharging air from the loading space back into the clean air path through a clean air filter; and
the clean air filter for purifying air discharged from the air supply means;
wherein an air flow path is created for circulating air from the loading space through the air supply means up into the clean air path and into the loading space via the racks. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14, 15)
wherein two air flows coexist, a first air flow for circulating air from the loading space through the air supply means up into the clean air path and into the loading space via the racks and a second air flow for circulating air from the loading space through the bottom floor to outside of the automatic warehouse via the bottom clean fan unit, for preventing air from settling at an upper part of the racks. -
