AIR CONDITIONING SYSTEM

PROBLEM TO BE SOLVED: To provide an air conditioning system capable of providing comfortable environment in a living room with a simple and inexpensive constitution. SOLUTION: A refrigerating cycle is formed by connecting a compressor, a four-way valve, a condenser, an expansion valve and an evaporator by piping in which a refrigerant is circulated, the air exchanging its heat by the condenser or the evaporator is supplied to an underfloor space 25 of a double floor composed of a floor slab 23 and a floor board 4 disposed in opposition to the floor slab 23, by a blower fan, and circulated into the living room 10 from the underfloor space 25. A void 45 formed in advance along between a side edge face of the floor board 4 and a wall surface of the living room 10 is utilized as a circulation port for circulating the heat-exchanged air to the living room 10 from the underfloor space 25, and a flow rate of the air circulated in the void 45 is 0.1-1.0 m/s.
