Abstract

PURPOSE:To inexpensively and efficiently exhaust the air without necessity of a large scale facility by disposing a gradually decreasing curved surface or oblique surface toward an exhaust port concentrically disposed at a ceiling of a large space, and generating a spiral rising air flow in the entire space. CONSTITUTION:An exhaust port 1 is concentrically disposed at a ceiling of a large space. A directional spiral air flow, i.e., a spiral flow 2 is formed in the entire space toward the concentrically disposed port 1. Directionality is imparted to the flow 2 as natural spiral flow to heat rising flow in the space. The formation of the flow 2 is facilitated by providing a convergent curved surface 3 directed toward the port 1 of a ceiling. Further, the surface 3 may be formed of a plate provided in the space or a curtain. A guide plate 4 may be provided of a plate or a curtain toward the port 1. The surface 3 may be so formed in a hyperboloid as to generate a Coanda effect on the surface.

In order to ventilate such a large space, usually, a large number of ventilation / air-conditioning devices are arranged in the periphery to forcefully exhaust the air. Further, in buildings other than the air dome, an exhaust port may be provided in the ceiling of the space. Such exhaust is generally 30 m 3 / person.
Time is considered as a goal. However, in this conventional exhaust method, the capital investment for the forced ventilation and its operating cost are enormous, and the burden thereof is extremely large. In addition, the conventional forced ventilation method is not very good in its exhaust efficiency itself.
