Radiant Wall and Glazing Heating-Cooling to Eliminate Drafts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current heating and air conditioning systems in vehicles and buildings suffer from discomfort due to air currents, poor temperature regulation, pollution entry, and high energy consumption, failing to effectively address temperature differences and health issues.
Innovation Solution
A device using radiant-type panels and triple or double-glazed surfaces with air renewal systems, where air is supplied at defined temperatures, and pollution is measured to control intake and exhaust, with temperature regulation via sensors and 'transfer' and 'night' modes to optimize comfort and energy efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If direct air heating and cooling systems are used, then air renewal and heating/cooling functions are provided, but air currents cause discomfort, neuralgia and rhinitis for occupants
Solution Approach 1:
The patent replaces the mechanical forced air circulation system with a radiant heating and cooling system that uses thermal radiation through panels and glazing surfaces. This substitution eliminates the harmful air currents while maintaining temperature regulation functionality, directly addressing the health and comfort issues caused by conventional air movement.
Solution Approach 2:
The invention extracts the air renewal function from the heating/cooling system, allowing them to operate independently. The air renewal system handles ventilation separately while the radiant system provides thermal comfort without requiring high-velocity air movement, thus eliminating the harmful effects of drafts while maintaining both functions.
2Temperature
If conventional air conditioning systems are used, then heating and cooling functions are provided, but they allow continuous penetration of pollution such as toxic hydrocarbon vapours, dust and pollen
Solution Approach 1:
The patent separates the air renewal function from the thermal regulation function. By extracting air renewal as an independent system with dedicated filters and controlled intake/exhaust points, the system can provide thorough pollution removal without relying on the heating/cooling air circulation, thus eliminating the pathway for pollution entry while maintaining temperature control.
3Area of stationary object
If high or very low temperatures are produced to heat or cool large volumes, then heating and cooling coverage is sufficient, but energy consumption increases significantly
Solution Approach 1:
The radiant heating and cooling system applies local quality by treating different surfaces (walls, ceiling, glazing) independently with appropriate thermal characteristics. Each surface can be optimized for its specific function and location, allowing efficient thermal regulation across large areas without requiring extreme temperatures, thus reducing energy consumption while maintaining comprehensive coverage.
4Object-affected harmful factors
If forced air systems with filters are used, then pollution filtration is provided, but filters must be changed frequently and pathogens may be transmitted
Solution Approach 1:
The invention extracts the filtration function from the forced air system and integrates it into a dedicated air renewal system with controlled intake and exhaust points. This separation allows for more effective filtration without the limitations of recirculating filters, reducing pathogen transmission risk and maintenance frequency while maintaining pollution filtration capability.
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
Significantly reduces drafts and pollution, improves comfort by addressing temperature differences, and lowers energy consumption through targeted air renewal and efficient temperature regulation.
Implementation Method 1
by a network of small-diameter pipes which transmit the heat or the cold mainly by conduction to the wall
Implementation Method 2
The air circulation comprises a circulation fan, supply and extraction vents distributed in the passenger compartment
Implementation Method 3
the insulation is completed for double glazing by an insulating or reflective film deposited on the inner face of the outer pane and for triple glazing by the air plenum located between the central pane and the outer pane

AI summary
The invention relates to a heating-cooling device that suppresses most air drafts and improves comfort in passenger compartments or buildings. The device essentially includes radiating panels arranged on the walls and/or the ceiling. A panel comprises 1 or 2 plates (33, 35) associated with an array of fine ducts (34) and an insulator (36). Heated or cooled air flows through the ducts (34) that can be integrated to the inner wall (33), which generates a radiating effect (32) on the inner side. The radiation can also be generated by glazed surfaces. The adjustment includes two "transfer" and "night" optimisation modes. The device of the invention is intended for heating-cooling any building and any transport means.
