Room Ventilation Layout Using Adjacent-Space Air Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ventilation systems in buildings, such as hotel rooms, face challenges with reduced ceiling height due to air conditioning unit placement and high installation costs, while also being visually unappealing and disruptive.
Innovation Solution
A ventilation device is placed in a separate room with air supply and exhaust connections made through sealed room zones, eliminating the need for additional air ducts and allowing for a modular design that can be expanded, with components like fans and heat exchangers, and integrated into the building's structure using existing walls and ceilings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If air conditioning units are installed in ceiling steps of hotel rooms, then heating and cooling functions are provided, but ceiling height is reduced and space is narrowed
Solution Approach 1:
The ventilation device is extracted from the first room (hotel room) and installed in the second room (corridor/lobby area). This separates the ventilation function from the living space, eliminating the need for ceiling steps in the hotel room while maintaining temperature control capabilities through the wall-opening-connected ventilation system.
2Ease of operation
If traditional ventilation systems with separate air ducts are installed, then ventilation function is provided, but device complexity and installation effort increase
Solution Approach 1:
The ventilation device housing is merged with the building structure by directly connecting it to wall openings. The housing serves multiple functions: protecting the ventilation device, providing structural support, and establishing air flow paths through integrated connections to supply and exhaust openings, eliminating the need for separate air ducts and reducing installation complexity.
Solution Approach 2:
The ventilation device housing performs multiple functions simultaneously: it protects the ventilation components, provides structural integration with the building wall, creates sealed air flow paths, and serves as the mounting structure for the ventilation device. This multi-functionality reduces the number of separate components needed and simplifies installation.
3Ease of operation
If ventilation equipment is installed in the first room, then ventilation is provided, but the equipment appears as a visual nuisance
Solution Approach 1:
The ventilation device is extracted from the visible interior space of the first room and installed in the second room (corridor/lobby). Only the functional wall openings remain visible in the first room, maintaining aesthetic appeal while the ventilation device operates effectively in the adjacent space where it is less visually intrusive.
