PROBLEM TO BE SOLVED: To realize an inexpensive and efficient in-structure thermal storage air-conditioning system. SOLUTION: Diffusion of air for air conditioning of indoor spaces is carried out by a plurality of variable air-volume units 3 connected to an air conditioner 1 through a duct 2. Control of supplying air to each room is made by the variable air-volume unit 3. The unit 3 is provided with a first outlet 5 for indoor air-conditioning, a second outlet 6 for thermal storage in a structure, and an outlet-switching means for making selection between the outlets 5, 6. In the nighttime thermal storage, cold or hot air is diffused from the outlet 6 to the structural body to store heat in it. The stored heat is used as a part of heat source for daytime air-conditioning. |
