Solution Overview
Problem
Current heating, cooling, and ventilation systems face challenges in achieving thermal comfort and flexibility, as they often rely on either convection or radiation, leading to inefficiencies and discomfort due to stratification and draft issues, and require extensive installation on ceiling surfaces, limiting adaptability in changing room configurations.
Innovation Solution
A modular island system that combines radiation and thermal convection, featuring a peripheral frame with a diffusion element, articulated deflectors, and thermostatic actuation to automatically adjust air flow direction and speed based on temperature, allowing for efficient heating, cooling, and ventilation without the need for extensive ceiling coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If air is blown perpendicular to the ceiling for heating, then heating effectiveness is improved, but cooling comfort deteriorates due to high-speed air currents
Solution Approach 1:
The motorized diffusion vanes dynamically adjust air flow direction based on mode. In heating mode, air is blown perpendicular to the ceiling to maximize heating effectiveness. In cooling mode, the vanes reorient to blow air horizontally along the ceiling at lower speeds, eliminating harmful air currents while maintaining cooling effectiveness.
2Device complexity
If a fixed diffusion angle is used for both heating and cooling, then device simplicity is maintained, but thermal comfort deteriorates due to suboptimal performance in both modes
Solution Approach 1:
The system automatically adjusts the diffusion angle based on the operational mode (heating or cooling) without requiring manual intervention. The motorized diffusion vanes are controlled by the system itself to optimize air flow direction for the current mode, providing self-service adjustment that maintains both device simplicity and thermal comfort.
3Ease of operation
If radiant panels are used for thermal diffusion, then thermal comfort is improved, but cooling power is limited due to dew point condensation risk
Solution Approach 1:
The patent merges radiant heating panels with a convective air diffusion system. The radiant panels provide thermal comfort through radiation, while the integrated motorized diffusion vanes provide convective cooling capability by directing air flow horizontally along the ceiling. This combination allows the system to achieve both high thermal comfort and sufficient cooling power without the condensation limitations of pure radiant systems.
4Ease of operation
If extensive ceiling coverage is installed for optimal thermal distribution, then thermal comfort is improved, but installation flexibility deteriorates due to inability to adapt to room reconfiguration
Solution Approach 1:
The system is divided into multiple independent modular units, each equipped with its own motorized diffusion vanes. These segmented modules can be installed on partial ceiling surfaces and can be independently adjusted or repositioned to adapt to room reconfiguration, while each module maintains optimal thermal distribution in its coverage area, thus preserving both thermal comfort and installation flexibility.
