Description

MULTI-FUNCTIONAL VALVE DEVICE FOR EXPELLING HUMIDITY AND SATURATED STEAM FOR BUILDING STRUCTURES Field of the invention The present invention relates to a multi-functional valve device for expelling humidity and saturated steam for building structures. Such device removes the risks of condensation inside conventional building walls and structures, coated with thermal coatings (also conventional), without application limits on multiple thermo-acoustic covers for doors or windows, or can also be integrated on various types of frames, windows, doors, thermal caissons and thermal coatings.

The check valve with ball-type shutter, even if known in hydraulics, according to the knowledge of the Applicant, has never been used nor is known in the building industry in general. Such type of valve is extremely reliable, when it is positioned both vertically, and horizontally, due to its construction simplicity and the absence of mechanisms.

Its operating principle is based on the free movement of the "ball" inside the valve body, and on the particular design of. the valve body with thermal ma-terials (so that the temperature of the passing fluid is not subjected to strong variations).

Moreover, the design of the ball drive and of the delivery duct guarantees a completely open passage, free of cloggings or asperities, that otherwise could stop every type of outflow, both of steam, and of humidity or water.

Due to the free passage that is created, load losses are very low. The valve ball has a low inertia and therefore the opening pressure of the check valve is about half the opening 2 pressure of a known valve, for example of the clapet type; the duct opening position is obtained without using springs or other mechanical means.

To obtain both a perfect seal, and a silent closing, the ball is made of phenolic resin or is coated with nitryl rubber resistant to clean, soft or sea water, to flowing or rain water, even with hydrocarbon residuals. The extreme conceptual simplicity of the valve makes it of a very long life and free from maintenance.

As is known, the realization of structures-building envelopes in all its partitions; such as foundations, walls, floors, roofs, doors, windows and frames, with thermoregulation functions, which have high performance characteristics and at the same time a good breathability is always a very sensitive issue in civil and industrial in the world.

Another very sensitive issue is to rehabilitate and what structures incorporating such as doors and windows, etc. that can be healed in less time.

A further object is to provide a device in multi-function valve for expulsion of moisture and saturated vapor consists of lightweight thermal materials to facilitate transportation and installation, as well as its functionality over time.

The present inventive multi-function valve device for expulsion of moisture and saturated steam, for its particular constructive characteristics, is capable of ensuring the greatest assurances standards of reliability and safety over time.

The inventive valve device finds wide application in various fields of construction, such as, for example, and without 3 limitation, for any type of frame of windows or doors, wood, aluminum, steel or the like; for the connectors / spacers of any material; in the cavities of building envelopes in general, made of brick or other conventional materials, and coated with thermal coat (External Thermal Insulation Composite Systems).

As said, the inventive device has the function, to evacuate moisture, the saturated steam and interstitial condensation that are created in any structure, is monolithic, is hollow, solving the so-called "sick building syndrome", known previously unsolved problem.

The inventive valve arrangement is based on the concept of enclosure, such as dynamic and interactive element of a complex energy system and hygrometric, which, via multiple valves multifunction integrated or applied subsequently, regulates the operation of the building and characterizes functionality, offering them an exclusive living comfort in all weather conditions, also very adverse. Legislation and Regulations Technical reference for such a device is the UNI EN ISO 13788:2003, Performance hygrometric components and building elements - Internal surface temperature to avoid critical surface humidity and interstitial condensation - Calculation, 01/06 / 2003.

To better understand the operation of the inventive device, we will discuss below the phenomena that it goes to counteract.

In particular, as regards the formation of condensation in the wall of a building and/or in the various partitions of the building structure, the primary requirement in order to maintain the performance of the building envelope is to avoid the risk of formation and accumulation of condensation, so that the duration 4 and the integrity of the building elements are not compromised, from the point of view both thermal, both because of the known structural deterioration.

The condensation can be of two types: - Surface when it affects the inner surface of the walls, due to the achievement of high values of relative humidity of indoor air, which creates in the vicinity of the corners of the walls, the appearance of condensation; - Interstitial when, inside the wall, creating the conditions of temperature and pressure such as to. achieve the conditions of dew.

The damage caused by the formation of condensation in the walls and/or in the building structure cause: - A decay of the performance characteristics of the walls, with consequent reduction of the degree of insulation of the wall due to moisture that there is contained; - A deterioration in the quality of life and comfort of the rooms bounded by these walls or structure; The appearance, on the surfaces of wall, of mold and efflorescence, with the consequent damaging of the finishing coats interior and exterior of the walls, such as plasterboard, plaster, etc.

The verification of the formation of condensation inside of each wall can be determined using the Glaser diagram, which is the graphical method through which, once known the temperature and humidity outside and inside, the temperature, the pressure and the thermal characteristics relating to the individual layers that make up the wall, they build the curve of the partial pressures and the curve relative to the saturation pressures, verifying, the presence of points of intersection between the two curves.

Where there are points of intersection, this means that in those points will occur conditions of temperature and pressure such as to bring the air to a state of saturation, and consequently in here points you will have condensation, advantageously and exclusively problem solved precisely by the application of the device to multi-function valve of the invention.

The condensate is formed in this way. The air contained in a given environment may contain a certain amount of water - in the form of water vapor in suspension. The amount of water vapor that may be contained in the air depends on two variables: temperature and pressure. This means that, the air may be contained a maximum amount of water for each value of temperature and pressure and that, once this limit is reached; it has a state of saturation of the air. This saturation implies that, for each increment of a quantity of steam in addition to the maximum limit value of the content, there is a precipitation of the steam in the form of condensate, for which it is obvious and necessary to apply multiple valve devices of the invention for the expulsion of moisture and saturated steam towards the outside.

It is clear that, in conditions of constant pressure, with an increase in air temperature corresponds to an increase of the amount of vapor that may be contained in it. Consequently, the lower the temperature, the lower the quantity of steam the air can hold. 6 Under normal conditions the air is not saturated, but contains a certain quantity of steam (g/kg) less than the value that would correspond to a situation of air saturation. This relationship between the weight of the vapor contained in the air and the weight of the vapor contained in the same saturated air is said "relative humidity", which is expressed as a percentage of absolute humidity. A value of 80% of relative humidity in the air, therefore, will be up to indicate that it contains 80% of the maximum quantity of water vapor that can be contained at that temperature. It has condensation when in an environment, in the presence of a certain relative humidity, the temperature decreases up to reach the saturation value, with the consequent precipitation of the vapor from the gaseous to the liquid (condensation), other condition in it becomes necessary to use the device of the invention for the expulsion of the condensate to the outside.

The "dew point" or "dew point temperature" indicates the temperature of the air, at which there will be the formation of condensate and then water. The considerations made so far, assuming applies to keep constant one of the two variables, for example the pressure that is created naturally, by varying the temperature and vice versa (ie even when the temperature is kept constant, by varying the pressure) . Consequently that define "partial pressure" is the pressure at which the steam contained in the air, at a given temperature, and "saturation pressure" the pressure value corresponding to a condition of saturation of the air at a given temperature. The relative humidity expresses the 7 ratio between the relative pressure and the saturation expressed as a percentage: Ur = Pr/Ps (in %) The verification of the condensation of the walls and/or partitions of the building structure preferably takes place through the so-called method of Glaser. The phenomenon of the formation of condensation on the walls as low in the corners and then spread across the surface of the buildings is created when you reach high values of relative humidity of indoor air of 'building envelope, thus determining the conditions for the formation of dew on the inner face of the walls and/or in the horizontal partitions. The condensation can also affect the inside of the wall, e.g when within the layers that compose it, occurring conditions of temperature and pressure such as to induce the condensation of water vapor, other negative condition in which it becomes necessary to use the device inventive’s expulsion of water vapor.

Whereas the water vapor present in an environment tends to move from an area in which the vapor pressure is higher to another in which this pressure is lower, a wall that divides two environments places in different temperature and pressure will crossed by a flow of steam, that passing through the various layers of the wall will meet an Obvious resistance. This resistance will be directly proportional to the thickness of the wall and to the characteristics of impermeability of the material of which it is composed, and therefore the value of D, a value that takes the name of "coefficient of resistance to the passage of steam", and indicates the resistance to the passage the vapor 8 of a certain material compared to that of air at the same temperature and pressure.

Another parameter useful for studying the phenomenon of condensation is the "coefficient of conductivity vapor barrier" or "permeability", indicated by M, that measures the amount of steam (kg) which crosses the thickness of 1 square meter for a difference unitary pressure.

The coefficients of resistance to the passage of sfeam and permeability are a feature of many building materials and are related to the density of the materials themselves. They can be obtained from appropriate tables contained in the Statement and European Community and ASTM international standards. The process by which, by relating the parameters relevant to the characteristics of the materials and the physical parameters of the layers that make up the wall and/or the building structure, it leads to the tracking of a diagram for the verification of the condensate in the wall, takes the procedure name Glaser. The diagram Glaser allows dimensioning the wall, both as concerns the thickness of the layers, both as regards the choice of materials that compose it, according to the characteristics of permeability of the same. The hygrometric parameters for the individual layers of the wall that are needed are: Temperature within each layer; -Partial pressure of each layer; -Saturation pressure at various temperatures; -Resistance to water vapor of the individual layers.

Once these parameters are known, the relative diagram is built, consisting of a curve of saturation pressures and a curve 9 of partial pressures. Comparing the curve of the partial pressures with the curve of the saturation pressures within the various layers of the wall, there may be cases: • the two curves have no points of intersection, and thus there is no danger of condensation; • the two curves have a point of tangency: in this case we have verified the conditions for the formation of condensate in a point and then simply a decrease in temperature or an increase in the relative pressure to cause the appearance of dew: even in this condition becomes obvious and essential to use the inventive device for expelling moisture; • the two curves have more points of intersection: in this case the section between the start point and the end point of the area of hypothetical intersection represents the portion of the masonry in which there is the formation of condensate, other situation that requires the use of the inventive device for the expulsion of moisture.

There are different reasons why the humidity can penetrate- the walls creating the effects already discussed in other sections.

It is important to recognize which are to implement the correct intervention and solve in this way the problem permanently and advantageously with the use of the inventive device in quantities necessary for the expulsion of humidity.

With reference to Figure 1, there is shown a site of application of the inventive device. In this Figure, the reference signs represent the following: Splashing water Slope - Water pressure hygroscopic Effect of Humidity Humidity Humidity rain due to chemical factors condensing humidity due to construction Water Filter lateral infiltration of moisture damage to plants Humidity geological or environmental humidity rising from the ground Area on which the inventive device has a full effect 1. Capillary humidity rising from the land If the insulation (horizontal) is missing or defective conventional porous building materials absorb humidity coming from the ground, contrary to the force of gravity, through the capillary system, in which situation it is essential to apply the inventive device for the expulsion of humidity in quantities necessary. 2A. hygroscopic moisture Each and every wall plaster contain, after drying, a certain amount of hygroscopic salts (which attract moisture) of its wall structure but also salts extraneous to it (for example the salts of the ground). Due to the continuous capillary rise of moisture, these salts protrude from the wall and from the land up to settle in the area of evaporation on the plaster or on painting. After a drying of the internal walls successful, plaster or on painting remain residues of salts capable of absorbing only a certain amount of moisture in the air: there is therefore the possibility that the wall dries within but that the plaster or paint with excessive levels of salts remain moist and here it becomes indispensable for the integration of the inventive device expulsion of constant moisture to the outside. 2B. Residual moisture - degree of humidity of the walls Of course the purpose of drying the damp walls is not to eliminate all moisture from the walls. A wall completely dry but 11 also impossible to obtain, it would be contrary to every comfort.

Advantageously, the inventive device regulates the microclimate of an environment ensuring the comfort, ejecting the excess moisture in a natural way. Each type of masonry and every kind of building material has a degree of residual moisture natural.

According to the situations, the temperatures and the use of the housing there are optimal residual moisture to reach. This matter is so important and delicate that some countries, such as Austria and Germany, have issued specific Normative for specific sector which describe various humidity levels to be achieved, in fact, the inventive device for expelling moisture advantageously meets every legislation even more restrictive.

For example, a classic brick building is totally saturated, e.g totally moist, when 25% of its weight consists of water (approximately 500 liters of water per cubic meter of the 'building block). In this way the conventional brick is water to 100%. So the maximum residual moisture is established has then when 5% of the weight of the brick consists of water (this percentage is then obtained from 20% of 25% = 5%). Also integrated into the brick inventive device for expelling moisture, advantageously provides the 'expulsion of excess moisture and allows perspiration. 3. Lateral infiltration of moisture In the presence for damage or defects in the insulation vertical (eg consider the outer walls of a cellar, which are usually in contact with the ground), moisture can penetrate laterally through the capillaries until you cross the entire wall.

More often it is the wall and the lower the humidity infiltration 12 by side, the better the results of expulsion of excess moisture through the valve device for multi-function invention. To have a house or building structure completely dry (inside and sideways) , you can use various devices of the invention advantageously placed in quantity 'needed, obtained by appropriate calculations to determine the' exact dumping moisture. 4. Water a slope with pressure The water that flows from a slope or a level of water in the soil temporarily high, exert a pressure on the masonry, penetrating. When it is inside the wall, the water is pushed upward through the capillary system (hydrostatic pressure): situation in which it is essential to apply the inventive device for the expulsion of humidity.

. Splashing water The rain, bouncing on a flat surface near the outer wall (concrete slabs, road or other), it hits the base. Obvious situation in which it is essential, to apply the inventive device for the expulsion of humidity. 6. Humidity caused by technical faults of construction, damage to installations This moisture comes from the lack of, or inadequate protection against ingress of rainwater (damage to the roof or roofing material, inadequately sealed fireplace, lack of protective material from the surface of the roof, chimneys unused.

Missing roof drainage etc) and/or pipeline damage (damage or clogging the gutters, clogging of drains, pipes, broken pipes, etc) situation where it is essential to implement the inventive device for expelling of humidity. 13 7. Moisture due to rain If the rain falling directly on the walls, the moisture penetrates the plaster is not waterproof or not plastered walls in a situation where it is essential to implement the inventive device for expelling of humidity. 8. Water infiltration Surface waters that are formed due to the precipitation can penetrate freely into the gaps between the ground and the wall of the building, so the walls below ground level (such as those of the cellars) often become very damp: the situation in which it is essential apply the inventive device for the expulsion of humidity. 9. Moisture due to construction, humidity caused by the new plaster The humidity is moisture construction remains "incorporated" into the wall or building structure when it is usually built in traditional materials such as brick, concrete block, etc. It evaporates slowly over about a year and a half or three years. In a recently plastered wall, the natural evaporation of the specific humidity of the plaster occurs in 1 or 2 years, and depends on the material and its thickness of the plaster. The complete process of drying of the plaster walls and instead can take place in a period of time greater than that reported for the two cases separately: the situation in which it is essential to apply the inventive device for the expulsion and evaporation of humidity, in times rapid to obtain a building structure before wetness.

. Humidity caused by disturbances geological or technical 14 Certain electromagnetic fields, electrostatic and/or other fields of different nature, brick, concrete block and by their very nature, can increase the humidity in the capillary wall.

Basically, there are two types of disturbances: Geological factors: are formed due to the presence of sources of water in the subsoil, underground streams that flow quickly, tectonic fractures, etc.; Disturbing Factors Technical transmitters are caused by television, radio, radar, cell- phones or other types of transmitters (producing the so-called "electro-smog" as certain preventive measures can reduce these waves), by electric conductors or insulated metal (pipes etc.) or by supports of lightning rods not isolated.

Even in this case the valve device multi-function invention plays a fundamental role in water evacuation and vapor diffusion. 11. Humidity Condensation The warm, moist air condenses on cooler wall surfaces. This creates the moisture from condensation. The causes are often due to a faulty thermal insulation due to thin outer walls (they create a bridge cold-hot), excessive humidity in the rooms (eg bathroom, bedroom, kitchen, laundry room, or rooms where there are aquariums many plants, etc.) airtight windows that do not allow moist air to escape, no ventilation, heating defective organic paint (emulsion paint), which is a breeding ground for mold, damp walls (which in winter cools faster than dry) : situation in which it is essential to implement the inventive device for expelling of humidity. 12. Humidity caused by chemical factors The different building materials have different chemical characteristics and quality. An example is the old wall that is slightly acidic and the cement plasters which are strongly alkaline (pH values = different). These effects cause a chemical transport of humidity electrochemical wall that _ attracts other humidity and/or maintain high humidity. Rusty materials (steel <'>pipes, iron frames etc.) Have a similar effect on the moisture in the walls. A complete drying of the walls is only possible situation where it is essential to implement the inventive device for expelling of humidity.

There is a specific cycle to block the infiltration of rising damp. The walls of the old buildings are often subject to ingress of moisture from the ground up. At the origin of the phenomenon is the porosity of the construction materials, which determines the capacity of the material to absorb water and to transport it to rising damp.

The action of water on the masonry involves a whole series of harmful consequences which manifests itself in the form of spots of humidity on the walls, efflorescence of water-soluble salts and then prejudicial to the building, friability of the bricks making up the wall, chalking of the material junction and plaster, flaking and detachment of parts of the coating mural, development of sponginess in the wall and the wooden parts used for the construction, proliferation of molds and microorganisms.

The most effective way to combat the phenomenon of rising damp is to use some devices of the present invention, for the evacuation of water and steam. 16 The process consists essentially in the introduction of some inventive devices by injection through holes in the masonry inclined channeled downwards, by natural gravity or better under pressure.

The problem of condensation of water vapor in building structures, whether it takes place on the surfaces of structures, whether it takes place within the same, is a risk in two ways: one linked to the preservation of buildings and that related to health environments.

It is rare to come across in the formation of mold, or watch the disintegration of plaster and masonry precisely because of these phenomena. In relatively recent years, the need to contain the heat loss has favored the adoption of indiscriminate frames endowed with excellent air tightness that, in the absence of mechanical ventilation, however, has resulted in a significant reduction of the natural ventilation with consequent additional burden of the problem under examination caused by the moisture present in ambient air.

It is then very widespread use in kitchens of filtering hoods, with no connections to ducts of the fumes expulsion, that the advantage of the compositional freedom of the kitchen furnishing contrast the disadvantage of placing large quantities of steam in the environment as a result the cooking of food.

The formation of condensation, a phenomenon typical of poorly insulated structures (thermal bridging) , can also occur even in the presence of well-isolated structures where, however, the placement of the insulating layer, is misplaced with respect to the permeability of the remaining layers. 17 It should also be taken not to confuse condensation with those due to the presence of water infiltrations, for example for capillary rise from the ground, to driving rain, for breaking water pipe, etc.

As stated above, you can see the complexity of dealing with the phenomenon, the resolution of which depends, however, on the exact understanding of the causes which determine it.

Said inventive device inserted in windows and/or frames in masonry super insulate exclusively and advantageously solves the aforementioned problems and known allowing a perfect breathability without energy consumption thanks to its special shape more later described.

As can be noted from the treatment of mixtures of dry air and water vapor, the condensation of water vapor occurs when the partial pressure of the same reaches the saturation pressure, the latter a function of temperature (condensation temperature or dew) ; at the same temperature, the higher the content of steam, and therefore the higher the relative humidity, the greater the risk of condensation (the condensation can occur even in the presence of modest cooling ambient air).

In order to verify the occurrence or not of the condensate must therefore always check that the temperature, surface and/or internal to the wall, is greater than the relative condensing temperature (e.g the partial pressure of steam is greater than the saturation pressure) . In the specific case, the analysis of the physical phenomenon relates to the molecular diffusion of a gas (water vapor) in a solid and is expressible by the Fick's law; simplifications deriving there from, together with the can 18 consider the vapor water a perfect gas, mean that the determination of the flow of steam that spreads inside a solid, it may be expressed in terms of the pressure gradient that occurs due to variations in temperature and therefore the density (or other terms to vary the concentration of water vapor in the air) ; the treatment of the problem then becomes quite similar from the point of view of physical and analytical to what was seen for the transmission of heat. The new physical parameter that characterizes the components is then the vapor permeability or diffusivity, which is a coefficient that represents the amount of steam that passes per unit time through a unit thickness of the material, due to a difference unitary pressure.

Oftentimes in literature, values of the resistance to the flow of steam are expressed in dimensionless form by means of the parameter μ, given by the ratio between the resistance to the flow of vapor of the material under examination and the reference assumed equal to the resistance to vapor diffusion to offer 'air for the same thickness; course for the air that is μ = 1.

For example, a resistance μ = 10 of a brickwork filled devoid of plaster, means that the test material has a permeability value less than that of air; convenience in the adoption of the values μ aforesaid, having to dealing with very small values of the permeability, is in the greater simplicity in calculations, and then in the lower risk of. committing errors with the units of measurement.

As regards the surface resistances to the passage of vapor, they can be held completely negligible compared to the resistance offered by the other building components, therefore the partial 19 pressure of the steam on the inner and outer faces of the component are assumed equal to the partial pressure of the vapor of air contacting surface.

The flow of steam takes place when you create a pressure differential; the direction of the flow goes from the warmer environment to the colder ones (the higher vapor content of the first corresponds to a higher pressure) , and then generally occurs from the inside to the external environments in both summer and winter.

In general it is noted that the internal condensation does not take place in the walls homogeneous, but in those multilayer.

In particular it is noted that if the layer facing the warm environment is richer in water vapor has a higher thermal conductivity, in which case the partial pressure of water vapor PV reaches high values in the areas of the wall that (a due to the low thermal resistance) are located at relatively low temperatures and accordingly with values of the saturation pressure PS modest: these areas are considered therefore at high risk of condensation (PV-PS).

The problem, as will be seen, can be addressed by providing an insulating layer towards the cold side (thermal coat-external thermal insulation), thus raising the temperature value and then the saturation pressure: situation in which it is essential to integrate the inventive device in quantities necessary for the expulsion of moisture.

To assess the risk of condensation you can take the road through analytical Fick's law determining the amount of vapor may be condensed, or you can solve the problem graphically using the Glaser diagram, this diagram is to represent together with the trend in temperature inside the structure but also the corresponding values of the saturation pressure; comparing the latter with the values of the partial pressures is able to determine the application of the inventive device to avoid any risk of condensation.
