PROBLEM TO BE SOLVED: To provide a displacement ventilation system capable of saving a space of a room forming an air conditioning space as a target of displacement ventilation. SOLUTION: In the displacement ventilation system 1, low temperature air having a temperature lower than that within the air conditioning space 2 is supplied to the air conditioning space 2 surrounded by a floor plate 4, a sidewall 6 and a ceiling plate 10 arranged to be separated from a building frame ceiling 8 downwardly, and high temperature air having a temperature higher than that of the low temperature air is lifted within the air conditioning space 2 and is discharged to outside of the air conditioning space 2, so as to ventilate inside of the air conditioning space 2. The displacement ventilation system 1 includes: an air supply port 16 for supplying the low temperature air to inside of the air conditioning space 2; and a main air discharge port 18 for discharging the high temperature air to outside of the air conditioning space 2. The air supply port 16 is opened on the lower face opposing to the floor plate 4 in a hanging part 28 positioned above a lower end of an air exhaust hood 32, formed of an air supply chamber 26 protruded from the ceiling plate 10 downwardly and hung from the ceiling plate 10.
