FLOOR FACE INDUCED AIRFLOW AIR CONDITIONING SYSTEM

PROBLEM TO BE SOLVED: To provide a floor face induced airflow air conditioning system capable of efficiently performing air conditioning and ventilation of a large space such as a factory discharging large amount of exhaust by a local exhaust ventilation of production equipment and exhausting equipment of the whole factory. SOLUTION: In this air conditioning system in the large space having a number of exhaust systems 20, 21, openings of a prescribed opening area penetrating through an outer wall, are formed on an upper part of one or more side walls 100a of a large-space building 100, an outside-air intake port 10 comprising a heat exchanger 13 for taking in fresh air, heating/cooling the taken fresh air as request, and releasing the same toward a floor face in yard, is disposed, the cooled/heated fresh air is conveyed as the floor face induced airflow C by Coanda effect with the floor face to exchange the heat in a desired air conditioned-space, and then the contaminated air hanging in an intermediate layer is raised by ascending airflow separated from the floor face, and exhausted by the local exhaust ventilation 21 disposed in yard and/or a ceiling exhaust system 20 disposed on a ceiling portion or an upper wall face.
