There are many LoRAs for interior design, but very few tailored for air conditioning design, and even fewer specifically for central air conditioning design.

You can use the following workflow to generate images:

This LoRA for central air conditioning ducted louver vents is already capable of generating many practical interior central air conditioning design images.

If you need to generate more precise images, it is best to specify the positions of the central air conditioning air supply outlet and return vent in the prompt, for example: Between the ceiling and the window, there is a long linear recessed central air conditioning supply outlet, with a central air conditioning return air vent below it, and no central air conditioning supply or return vents on any other walls.

Since this LoRA is designed for the F.1 model and supports natural language, you can directly translate the prompt above into English:

Between the ceiling and the window, there is a long recessed central air conditioning outlet, and there is a central air conditioning return air outlet below the central air conditioning outlet, and there is no central air conditioning outlet and return air outlet on other walls.

 The above example places the central air conditioning vent between the ceiling and the window; please adjust it according to your actual scenario.

Sample Prompt:

nuantool,Hyper-realistic 8K renderings present the texture of urban light luxury: the warm and cold dialogue between champagne gold metal and matte microcement, the collision of glass and carbon fiber materials, and the virtual and real interaction between dynamic light and shadow and static sculpture. In the 15° upward viewing angle, the suspended bed resembles a futuristic space capsule, and the precision array of the air-conditioning grille and the technological sense of atomized glass form a rhythm of "mechanical aesthetics", realizing the fashionable bedroom philosophy of "less is more" through "hidden intelligence" (sensors = decorative components, pipes = spatial lines).

  Wall-mounted units, floor-standing units, ceiling cassettes, and other HVAC products are coming soon. Stay tuned!
