The invention discloses a projection system without a machine room. The projection system without the machine room comprises a movie projection hall and a network control projector, wherein a projection server is connected with the network control projector through a network connecting wire; a closed box body where the network control projector is placed is arranged on the lower side of a ceiling of a rear wall of the projection hall, a lift is arranged on the lower side of a stand of the rear wall of the movie projection hall, a push arm of the lift is fixedly connected with the box body, and a projection window is arranged at the front end of the box body. According to the projection system without the machine room, the construction cost is greatly reduced, a conventional projection device interlayer is omitted, and the area of the conventional machine room can be reasonably changed into the area of the movie projection hall so as to increase the number of chairs; due to an installed locking device, the phenomenon that a whole system suddenly falls due to the fact that a device has a fault is avoided, quite good safety measures are taken, scheme details can be flexibly changed according to different environments, and the purpose that the scheme adapts to the environment is achieved.
