Beschreibung
Zusammenfassung:	A projection apparatus includes a plurality of two-fluid nozzles, a projection-apparatus-side-gas-flow-path, a gas valve, a projection-apparatus-side-liquid-flow-path, a liquid valve, a projector, a mist concentration measurer, and a controller. The controller starts and stops spraying of a mist by controlling the gas valve and the liquid valve on the basis of an image or a video projected onto a screen from the projector. The controller receives a signal indicating a mist concentration from the mist concentration measurer, starts and stops spraying of the mist by controlling the gas valve and the liquid valve on the basis of the received signal, and thus controls the mist concentration.
