Set for ventilation of a room
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost of installing continuous laboratory ventilation systems makes it economically challenging to provide targeted ventilation in elongated rooms, particularly in laboratories, where efficient air distribution over the entire length is necessary.
Innovation Solution
A ventilation system comprising ceiling modules and connection modules arranged in series, where air flows from one ceiling module through a connection module to another without leaving the system, reducing the need for cost-intensive ceiling modules and allowing air distribution along the length of the room, with connection modules serving primarily for air conduction and not direct ventilation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If continuous laboratory ventilation systems are installed to provide targeted ventilation in elongated rooms, then ventilation efficiency is improved, but installation cost increases significantly
Solution Approach 1:
The ventilation system is divided into multiple ceiling modules arranged in series along the elongated room. Each module handles a specific section, allowing the system to cover long distances without requiring a single continuous expensive installation. The modules can be independently installed and configured.
Solution Approach 2:
Connection modules are introduced as intermediary elements between ceiling modules to conduct air from one module to the next. These connection modules serve as mediators that enable air flow continuity while reducing the need for expensive continuous ceiling module installation throughout the entire elongated room.
2Productivity
If ceiling modules are arranged in series with connection modules to distribute air along room length, then air distribution efficiency is improved, but system complexity increases
Solution Approach 1:
The connection modules serve multiple functions: they conduct air between ceiling modules, provide structural connection points, and maintain air flow continuity. This multi-functionality reduces the need for separate dedicated components, thereby managing system complexity while improving air distribution efficiency.
Solution Approach 2:
The system is segmented into standardized ceiling modules and connection modules that can be repeatedly assembled along the room length. This modular segmentation simplifies the overall system design by using identical repeating units rather than custom-designed continuous systems.
3Ease of manufacture
If connection modules are used primarily for air conduction rather than direct ventilation, then cost is reduced, but ventilation coverage may be limited
Solution Approach 1:
Connection modules act as intermediaries that transport air from ceiling modules to subsequent ceiling modules. While they don't provide direct ventilation themselves, they enable the air to reach distant ceiling modules that do provide ventilation, thereby extending the overall ventilation coverage across the elongated room at reduced cost.
Solution Approach 2:
The connection modules enable the ceiling modules to serve themselves by providing the air conduction infrastructure needed for air to reach multiple ceiling modules. Each ceiling module ventilates its local area while the connection modules automatically conduct air between them, creating a self-sustaining ventilation network.

Function Achieved in This Case
This configuration enables efficient and cost-effective ventilation of elongated rooms by distributing primary air along the room length, reducing investment costs and maintaining a constant air flow without significant constrictions, thus optimizing air distribution and reducing the need for separate ventilation components.
Implementation Method 1
at least one wall of a ceiling module and the connecting module each have at least one overflow cross-section, by means of which air can be routed at least indirectly, preferably directly, between the modules

AI summary
The present application relates to a room with an elongated set (1) for ventilating the room, in particular a laboratory, comprising at least one primary air connection (2) by means of which primary air can be supplied to the set (1), at least two arranged in a ceiling area of the room Ceiling modules (3) and at least one connection module (4) arranged in the ceiling area (3) of the room, wherein a width (6) of the set (1) measured perpendicularly to a longitudinal axis (5) of the set (1) is at least twice as large such as a height (7) of the set (1) measured perpendicularly to the longitudinal axis (5) and perpendicularly to the width (6), the ceiling modules (3) each having at least one ceiling space (9) spatially delimited by walls (8), at least an air inlet opening (10) for introducing air into the ceiling space (9) and at least one air outlet opening (11) for introducing air from the ceiling space (9) into the room to be ventilated, the air outlet opening (11) being in a lateral wall (12) of the respective ceiling module (3), the connection module (4) comprising at least one spatially limited connection space (13), at least two air openings (14) for introducing air into the connection space (13) and/or discharging air Air out of the connection space (13), at least one wall (8) of a ceiling module (3) and the connection module (4) each having at least one overflow cross section (16), by means of which air is at least indirectly drawn between the respective ceiling space (9) and a corresponding connection space (13) can be routed, with a direct transfer of air from the connection space (13) into the space to be ventilated being at least essentially prevented. In order to provide a set that enables reliable ventilation of an elongated room, in particular a laboratory room, using comparatively little financial resources, the invention proposes that the ceiling modules (3) and the at least one connection module (4) be installed in the longitudinal direction of the set (1) considered to be arranged one behind the other in terms of flow technology in such a way that an air particle, starting from a first ceiling module (3), can be guided into a further ceiling module (3) exclusively by means of flow through the connecting module (4).
