Ceiling Air Terminal Installation Using Drop-Down Swing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Air conditioning terminal devices in ship cabins face installation challenges due to limited vertical space, often damaging the flexible hose or preventing proper installation when cabin modules are pushed into place, affecting air flow and temperature control.
Innovation Solution
A sliding and swinging mechanism allows the terminal device to be dropped through a ceiling opening with the supply air inlet foremost, using installation means like slide rails and support beams, enabling it to be installed below the ceiling initially and then lifted back into place, with optional turbulence reduction plates in the supply air pipe adapter to improve airflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal device is installed above the ceiling in its operating position during cabin construction, then air conditioning function is provided, but the terminal device may hit a horizontal beam and be damaged or prevent installation of the cabin
Solution Approach 1:
The terminal device is dropped into the cabin space before the cabin module is pushed into place on the ship. This preliminary positioning allows the terminal device to be installed in a supported position where it cannot interfere with the cabin installation process, eliminating the risk of damage from horizontal beams while ensuring air conditioning functionality is ready for operation
Solution Approach 2:
The installation process utilizes vertical movement through a ceiling opening to transition the terminal device from an accessible installation position to its final operating position above the ceiling. By moving the terminal device through the third dimension (vertical axis), the solution resolves the spatial conflict between installation accessibility and operational positioning
2Ease of operation
If a flexible hose is used as an inlet pipe and the terminal device is dropped into the cabin, then installation is enabled, but the flexible hose may be damaged while bending affecting air flow and temperature control
Solution Approach 1:
A rigid or semi-rigid supply air inlet pipe with a bending section is used as an intermediary between the flexible hose and the terminal device. The bending section is specifically designed to accommodate the curvature required during installation while protecting the flexible hose from direct bending stresses, thus maintaining hose integrity and ensuring proper air flow and temperature control
Solution Approach 2:
The supply air inlet pipe is designed with a pre-formed bending section that anticipates and absorbs the curvature requirements of the installation process. This beforehand preparation cushions the flexible hose from excessive bending stresses that would otherwise occur during terminal device installation, preventing damage before it can happen

AI summary
The invention relates to a method comprising moving a supply air terminal device (110) attachable to a ceiling of a space to be air conditioned at least partly above the ceiling between an operating position and a supported position. The terminal device is moved through an opening arranged in the ceiling in a position where a side of supply air inlet is towards the space to be air conditioned. The invention also relates to an air conditioning apparatus including a mechanism for dropping a terminal device through an opening arranged in a ceiling into a space to be air conditioned with a side of supply air inlet foremost. The invention also relates to a habitable room, such as a ship cabin or similar.
