PROBLEM TO BE SOLVED: To reduce the laying cost for a duct, and prevent due condensation formed on a ceiling surface. SOLUTION: A ductless air conditioning system is adapted such that air conditioned air is supplied to a ceiling closed space formed in the ceiling of an air conditioned room, and the air conditioning air is blown out from the ceiling closed space to the air conditioned room without passage through a duct. In the ductless air conditioned system, there are provided an air mixing part 9 for forming conditioning air with mixed air of air conditioned primary supply air and return air from the air conditioned room, and a fan 2 for sending the mixed air from the mixing pat 9 into the ceiling closed space. An air supply chamber 3 is connected with the fan 2 for sending the air conditioning air from a blowoff outlet 19 into the ceiling closed space. The fan 2 is constructed as an air volume variable fan capable of altering the volume of sent air in response to a heat load. |
