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

VSEngineering 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

Engineering Contradiction:
Improveoccupant comfortVSAvoidair currents causing discomfort and health issues
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

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.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

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.

Inventive Principle:
Principle #2Taking out (Extraction)

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

Engineering Contradiction:
Improvetemperature regulationVSAvoidpollution entry
Core Design Contradiction:
TemperatureVSObject-affected harmful factors

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.

Inventive Principle:
Principle #2Taking out (Extraction)

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

Engineering Contradiction:
Improveheating and cooling coverage areaVSAvoidenergy consumption
Core Design Contradiction:
Area of stationary objectVSUse of energy by moving object

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.

Inventive Principle:
Principle #3Local quality

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

Engineering Contradiction:
Improvepollution filtrationVSAvoidpathogen transmission risk and maintenance frequency
Core Design Contradiction:
Object-affected harmful factorsVSReliability

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.

Inventive Principle:
Principle #2Taking out (Extraction)

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.
