Solution Overview
Problem
Current air flow regulation members for ventilation, heating, and air conditioning systems in the tertiary sector lack efficient control over fresh air flow rates per zone and centralized distribution of fresh air, leading to suboptimal air quality and comfort in multi-zone premises.
Innovation Solution
An air flow regulation member with pivotally mounted flaps for temperature-controlled and fresh air flow outlets, allowing independent regulation of air flow rates and centralized fresh air distribution, featuring a box design with separate compartments for temperature-controlled and fresh air flows, and adjustable components for external operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional air flow regulation members are used, then the system structure is simple, but the control precision of fresh air flow rate per zone is insufficient
Solution Approach 1:
The air flow regulation member is divided into separate compartments for temperature-controlled air flow and fresh air flow, with independent flap devices for each. This segmentation allows precise independent control of fresh air flow rates per zone while maintaining a modular structure that doesn't excessively complicate the overall system.
Solution Approach 2:
The patent employs pivotally mounted flaps that can dynamically adjust to different positions to control air flow rates. The first flap device controls temperature-controlled air flow while the second flap device controls fresh air flow, providing dynamic and precise regulation capability for each zone.
2Ease of operation
If centralized fresh air distribution is implemented, then air quality and comfort are improved, but the device complexity increases
Solution Approach 1:
The air flow regulation member serves multiple functions: it distributes both temperature-controlled air flow and fresh air flow, regulates flow rates for multiple zones, and provides centralized control capability. This multi-functionality allows improved air quality and comfort management without requiring separate devices for each function.
Solution Approach 2:
The regulation member acts as an intermediary device between the air treatment system and the distribution ducts. It centralizes the distribution of fresh air flow and controls flow rates before air enters the ducts, thereby improving air quality and comfort while maintaining a manageable structural complexity.
3Ease of operation
If adjustable components are added for external operation, then ease of adjustment is improved, but the device complexity increases
Solution Approach 1:
The flap devices are designed to be adjustable from outside the regulation member, allowing operators to directly control air flow rates without requiring disassembly or complex internal access. This self-service capability improves ease of operation while keeping the component structure relatively simple and maintenance-friendly.
