PROBLEM TO BE SOLVED: To provide an air supply chamber for replacement ventilation capable of reducing discomfort by a draft, and reducing a difference of upper and lower temperatures in a living area without increasing facility cost. SOLUTION: The air supply chamber 20 for supplying low temperature air to an inside of an air conditioned space 10 where replacement ventilation is conducted, is provided with air supply ports 15 of the low temperature air formed on a front surface. A fin 30 for feeding a swirling component to the low temperature air is provided on the air supply ports 15. The swirling components of the low temperature air blown out from the adjacent air supply ports 15 form mutually opposite rotation directions. When the swirling components are given to the low temperature air SA blown out in the air conditioned space 10, induced volume of air (an induced rate) in the air conditioned space 10 induced by the blown-out low temperature air SA can be increased.
