Description

INNER TEMPERATURE MODIFICATION SYSTEM BASED ON AIR CIRCULATION
WITH REFLECTIVE THERMAL PANEL
OBJECT OF THE INVENTION
The present invention may be included in the technical field of building, in particular, within the field of constructive systems or conditioning of buildings or premises, including upper areas such as roofs, as well as the construction or adaptation of already existing premises, such as factory premises or equipment. More particularly, the invention refers to an inner temperature modification system based on air circulation having a thermal reflective panel.
BACKGROUND OF THE INVENTION In the 70s in the XX century, as a result of the energy crisis, with the "boom" of renewable energy sources, the bioclimatic architecture, etc., the effect of the built space began to be taken under consideration, with the purpose of pollution reduction and energy conservation. Nowadays, the greenhouse effect problem, ecology issues and sustainability of spaces, make this research line in the architecture field and urban planning be the focus of attention. The control of the urban micro climatic conditions is fundamental both for energy efficiency and reduction of emissions, so as to guarantee comfortable living spaces for citizens.
The most noteworthy features of the urban microclimate appears as a temperature increase, as the reduction of the daily temperature range, as a particular distribution of the city winds, as a consequence of the friction with buildings and canalization in the avenues, and as an hydric balance being different to that in rural spaces.
It is known that the effects due to urbanization and construction of structures with solid materials directly influences on heat increase in a house, building or storage place, this leading to modification of microclimatic conditions within the spaces and areas where human beings work, live or where products are stored, above all in summer and in those places characterized by the high temperature thereof, causing discomfort problems both in outdoor areas and in indoor areas, thus increasing the energy demand for refrigeration.
If the local temperature increase is added to the increase being expected from climate change, risk conditions could be generated in the cities for its inhabitants' health, as well as problems related to energy consumption and supply.
The problem of cooling the buildings in warm climates is very important, since it may involve energy consumption and emissions being higher than those produced by heating. In the last decades the consumption for refrigeration has shot up, especially in European cities. It has to be taken into account that the air conditioning systems use electric energy, which creates considerable problems in the energy supply, as well as leading to an increase in greenhouse gases emissions, of pollutants such as sulphide dioxides, carbon monoxide, nitrogen oxides and of volatile particles produced by power generation plants.
The solutions found currently only define a specific problem to be solved and they do not offer a complete solution for heat insulation and cooling in the same device as specified in US8635824B2 (Scherrer) and US7882669B2 (Qu). As it can be observed, there are no modular systems incorporating in the same panel heat insulation components and air piping for refrigeration.
DESCRIPTION OF THE INVENTION The present invention refers to an inner temperature modification system based on air circulation having a smart reflective thermal panel, intended for being part of a coating for thermal insulation in buildings.
The system of the invention comprises a smart thermal reflective panel. The thermal panel may be generally applied, among others, for thermally insulating surfaces, including roofs, from buildings or industrial premises or equipment, undergoing high heat exposure because of solar radiation. The thermal panel comprises an outer reflective layer, comprising photopolymers, so as to reflect incident light, further comprising two insulating layers as well, located more internally to the reflective layer, an air chamber formed between both insulating layers, so as to evacuate air from the panel into the outside, and ducts for conveying air inside the air chamber.
The reflecting layer with the photopolymer coating provides the capacity of thermally insulating building surfaces (walls, outer walls) undergoing high heat exposure because of solar radiation.
The thermal panel provides for easy installation and removal thereof by using expanding bolts. This thermal panel is used for efficiently reducing and optimizing the inner temperature within the areas where it has been installed. The thermal panel and the constructive system are highly water and fire resistant. They do not release toxic gases.
Additionally, due to their modular nature, they allow installation thereof inside buildings or premises which require improvements in product preservation. The thermal panel and the system can be removed in cases where they are not necessary and reinstalled when they are required.
The thermal panel is part of a thermal insulating system for building having an inner cooling or heating system, based on cool or hot air circulation, which allows raising or lowering the inner temperature of the coated area so as to optimize the preservation or habitability processes.
This smart device is characterized in that: (1 ) it adapts the temperature in buildings, houses or premises being indicated and preferred by the user; (2) It allows cold or heat to flow uniformly throughout the whole building where it is required; (3) it provides human beings, products or items being inside a premise with adequate comfort, protection and preservation; (4) by being modular and removable it allows using the necessary amount; (5) and it contributes to energy saving and preservation of the planet. The thermal panel of the invention allows thermal insulation of both upper and side surfaces of already existing buildings or buildings to be built, both in inside or outside areas of premises, factory premises or industrial equipment undergoing high exposure to solar radiation. Its operation encompasses the following: it reduces heat absorption, it conducts inside thereof the heat being received and it acts as a stop for thermal radiation, as well as allowing hot air circulation. It is used for efficiently reducing and optimizing the inner temperature within the area where it has been installed. It is highly water and fire resistant. It does not release toxic gases. For all the above, the system of the invention constitutes a smart device capable of providing heat insulation and refrigeration by means of structural layers being joint together in a single component, that increases the energy saving efficiency, improves the micro-climate of the space where it is located and keeps a more comfortable environment of the place according to the needs thereof.
