A RADIANT BARRIER AND VENTILATION SYSTEM FOR THERMAL MANAGEMENT

FIELD OF INVENTION:

The present invention relates to a radiant barrier and ventilation system for thermal management. Particularly it relates to a radiant barrier and ventilation system for thermal management to have energy-efficient management of various structures.

BACKGROUND OF INVENTION:

In the face of escalating global warming concerns, the need to develop sustainable solutions for managing thermal parameters within structures has become increasingly pressing. As various activities continue to elevate atmospheric greenhouse gas concentrations, resulting in adverse climatic shifts and amplified energy demands for indoor climate control, the need for innovative thermal management technologies has become ever more apparent.

The phenomenon of global warming, driven primarily by the release of carbon dioxide and other greenhouse gases into the atmosphere, has led to rising temperatures worldwide. This escalation in temperature demands for cooling systems in various structures, which in turn contributes to a vicious cycle of increased energy consumption and heightened carbon emissions. Consequently, there is an urgent call for sustainable interventions that can effectively mitigate heat gain and loss within structures, thereby reducing reliance on energy-intensive cooling mechanisms.

One such invention is disclosed in Patent “US9255406B1” Titled - Insulating and venting assembly. The invention discloses an effective insulation and ventilating assembly that can insulate a structure, usually in roofing or exterior wall applications, from conductive, convective and radiant heat. The insulating and venting assembly is comprised of a rigid foam sheet and a rigid panel such as oriented strand board (OSB) or plywood attached one or both sides of the rigid foam sheet. The rigid foam sheet has air spacer columns and air spaces on one or both faces. Radiant barrier layers can be applied to either faces of the rigid panels and/or can be applied to the air spacer and air space surfaces allowing for radiant heat to be radiating back or radiant heat to not be reradiated by the radiant barrier low emissivity surface. The air spaces in the rigid foam face allows air and moisture to be vented though the insulating and venting assembly.

One such invention is disclosed in Patent “US4509307A” Titled - Heat insulating panel. The invention discloses curling of a composite roofing panel having a core of polymeric foam is inhibited by providing the core with at least one slit which opens through opposed edges of the panel and also through one of the major surfaces of the panel, adhering to that one of the major surfaces a lamina of non-foam material which is interrupted by the slit, covering the open edge of the slit with an elongated flexible tranversely strong tape adhesively secured to the portions of said at least one lamina adjacent the slit, and providing at least one additional lamina of non-foam material which overlies and is secured to the other major surface of the core and extends in unbroken fashion across the location of the slit, the slit affording space for relief of stresses resulting from shrinkage of the polymeric foam due to uneven loss of moisture and thereby inhibiting curling of the panel, the tape providing supplemental structural strength to allow handling of the panel despite presence of the slit, yet allowing limited movement of the side walls of the slit relative to each other as said stresses are relieved.

The problem associated with the cited prior arts are that the foam sheets based insulation are not adequately resistant to weathering. Further condensation may increase the degradation rate. The foam sheets being wider occupy more space. In light of these challenges and to overcome the above mentioned issues the inventor of the present invention has developed a radiant barrier and ventilation system for thermal management. The development of a radiant barrier and ventilation system for thermal management emerges as a crucial innovation. By leveraging reflective materials to intercept and redirect radiant heat, such a system offers a sustainable solution to curtail heat transfer within structures. By reducing the amount of heat absorbed by building materials, these barriers can significantly alleviate the burden on cooling systems during hot weather conditions and reduce heating demands in colder climates.

OBJECT OF INVENTION

Another object of the present invention is to provide is to offer a sustainable system that minimizes reliance on energy-intensive cooling or heating systems, thereby reducing overall energy consumption and environmental impact.

Another object of the present invention is to leverage the natural flow of air to dissipate heat away from the structure, enhancing cooling efficiency without the need for mechanical ventilation systems.

Another object of the present invention is to utilize materials that effectively radiate heat while acting as a barrier between the structure's walls and the ambient air.

Another object of the present invention is to improve indoor comfort levels by efficiently managing heat transfer, maintaining stable temperatures throughout the structure, and reducing the reliance on artificial heating or cooling methods.

Another object of the present invention is to provide a system resilient to weathering, capable of effectively managing condensation without compromising the integrity or durability of the materials used.

Another objective of the present invention is to provide a system that enhances the ventilation of the structure without the need of an external power source.
