Ventilation valve, method and system for ventilation of a space for animals or plants
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ventilation valves for animal or plant spaces have insufficient air throw and poor controllability, especially at minimal flow rates, leading to inefficient air mixing and potential freezing issues due to leakage.
Innovation Solution
A ventilation valve with a profiled edge and aerodynamically shaped edges, providing a non-linear relation between passage opening and panel movement, ensuring a good air throw and airtight closure, and optionally a separate top-piece for enhanced control and direction of air current.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If conventional linear opening valves are used, then the valve structure is simple, but the air throw is insufficient at minimal flow rates
Solution Approach 1:
The patent applies curvature by providing a profiled edge with a non-linear edge contour on the circumferential framework. This curved geometric feature creates a non-linear relation between passage opening and panel movement, extending air throw in the minimum opening range while maintaining a relatively simple valve structure.
2Ease of operation
If conventional ventilation valves are used, then the valve is easy to manufacture, but controllability of air flow is poor
Solution Approach 1:
The patent applies local quality by providing aerodynamically shaped edges at specific locations (inflow side and profiled edge) rather than changing the entire valve structure. This localized geometric modification improves air flow controllability and mixing while keeping the overall manufacturing process relatively simple.
3Productivity
If conventional valves are used, then the structure is simple, but air mixing efficiency is poor
Solution Approach 1:
The aerodynamically shaped edges and profiled edge with non-linear contour create optimized air flow patterns that enhance mixing efficiency. The curved geometric features guide air flow more effectively through the space, improving productivity without requiring complex multi-component valve structures.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution ensures better air distribution and reduced energy consumption by maintaining all valves in use, with improved air mixing and prevention of freezing, while allowing for precise control of air flow and exit angle.
Implementation Method 1
on the circumferential framework a profiled edge is provided which in an initial opening range between the fully closed position and a predetermined partly opened position provides a non-linear relation between a passage opening for the ventilating air and an associated relative movement position, or opening position, of the panel relative to the circumferential framework
Implementation Method 2
aerodynamically shaped edges on the inflow side for a higher air output

AI summary
A ventilation valve (1; 101) for ventilation of a space for keeping animals or plants includes an opening-defining circumferential framework (3; 103) for mounting in a wall of that space, and a movable panel (5; 105). The panel (5; 105) is movably attached to the framework (3; 103) for relative movement between a fully closed position, in which substantially no air can pass between the framework and the panel, and a fully open position, in which substantially the complete opening is available for passage of air. A profiled edge on the framework provides a non-linear relation between a passage opening and an opening position of the panel (5; 105). Also provided is a system for ventilating the space, having at least a single ventilation valve, and for periodically determining parameters of inside air in the space, and adjusting the opening position of the valve based on the parameters.
