    DESCRIPTION
    Ventilation system for ventilated facade with closed joint Technical field of the invention
    The present invention corresponds to the technical field of construction, in particular to the closing of facades by ventilated facades, these being of closed joint and presenting externally to a layer of support factory, an insulation layer and an outer layer of the facade fastened to the layer of support factory by means of uprights.
    Background of the Invention
    There are currently several ventilated facade systems, which are characterized by incorporating a ventilated air chamber between the outer layer of the facade and the continuous insulation along it.
    The purpose of this type of facades is to dissipate the heat absorbed by the external skin when direct solar radiation strikes it, and thereby reduce the temperature of the inner sheet and therefore that of the interior space of the building. Its operation is based on the natural convection of the air due to the increase in its temperature. In this way, an upward flow of air is created through the chamber, which dissipates heat from the outer layer, to finally be expelled to the outside by the top of the facade.
    The ventilated facades of open joint, allow the free circulation of air between the chamber and the outside through the existing joints between the pieces that make up the outer skin. In this type of facades, air normally enters from the outside into the chamber through the joints of the lower half of the facade, and gradually leaves the exterior through the upper joints.
    In the ventilated facades of closed joint, there are no open joints between the pieces that make up the outer layer, so that the air enters the chamber through an opening or grid located at the bottom of the facade, and goes outside by another opening or grid in the coronation of the facade.

    Ventilated facades are especially indicated in climates with hot summer periods, and in orientations exposed to direct solar radiation. Under these conditions, solar radiation can increase the surface temperature of the facade by more than 30 ° C, so that the dissipation of this heat by means of the ventilated chamber means an important energy saving in the air conditioning systems.
    However, in cold periods, when the outside temperature is lower than the interior comfort temperature, this type of facades is an inconvenience because it does not take advantage of the heat that the facade can absorb by solar radiation on sunny days.
    There are control systems for closing the chamber that allow the chamber air to be occluded during these periods and prevent its ventilation, thus configuring itself as a closed chamber capturing heat, obtaining energy gain in front of a ventilated facade with the chamber open.
    As an example of the state of the art, reference documents ES2435091 and ES2477715 can be mentioned.
    Document ES2435091 defines a self-ventilated prefabricated facade composed of a plurality of panels where each panel comprises a layer of exterior finishing material, at least one ventilation air chamber and at least one layer of thermal-acoustic insulation where each panel forms a unique piece and the ventilation air chamber is comprised between the layer of exterior finishing material and the layer of thermal-acoustic insulation, crossing completely each panel vertically forming upper and lower openings to ensure effective air circulation and being communicated through transverse channels and provided with lateral openings.
    The ventilation air chamber of this façade passes through each panel vertically and forms openings at the upper and lower ends to ensure air circulation.
    In this case it is observed that the proposed ventilated façade presents a permanent communication with the outside, so in hot periods it is an advantage, but in cold periods the opposite will occur due to the heat absorbed by the facade and passing to the ventilation chamber, escapes through the openings and is not used for the supply of heat inside the building.

    On the other hand, the document ES2477715 refers to a device for ventilating two-leaf facades with an internal air chamber, formed by an envelope which has holes, a rotating rod, a control coupled to the rod and a gate that runs over a slide, intended to be arranged on the outer sheet of the facade. The enclosure of this device has holes outside at the end that is on the outer sheet of the facade, as well as one or several holes inside towards the inner chamber between the two sheets.
    The holes to the outside have some gates that allow their closing, which are moved by actuating a rod from the inside of the wall by means of a knob, which is arranged as the only visible part from the inside of the construction to which The facade belongs.
    In this case, it is observed that this facade has a device that tries to solve the problem existing in the first document, by closing the communication of the ventilation chamber with the outside in cases where it is convenient, as in the periods of low temperatures.
    However, this type of ventilated facade continues to present problems. Thus, in the case of hot periods, the chamber remains connected to the outside and the ventilation air that circulates through it, due to contact with the outer layer of the facade, gradually increases its temperature as it rises by the chamber, so that in the lower area of the facade, the air in the chamber has approximately the outside temperature and therefore the efficiency of the system is maximum, while in the upper area, the chamber air acquires a high temperature, and therefore in this area of the building the system loses its effectiveness.

    Detailed description of a preferred embodiment of the invention
    In view of the figures provided, it can be observed that in a preferred embodiment of the invention, the ventilation system for ventilated façade with a closed joint, comprising externally to a support layer 15, an insulating layer 3 and an outer layer 4 of the facade fastens the support factory layer by means of uprights 5 proposed herein, comprising a double ventilation chamber, disposed between the outer layer 4 of the facade and the insulation layer 3 thereof and , at least one air intake and expulsion device 6 disposed on the facade.
    As shown in Figures 1 and 2, the intake and ejection devices 6 are located in the coronation of the roof breastplate and on the double ventilation chamber.
    The double ventilation chamber is formed by a first chamber 1 located adjacent to the outer layer 4, a second chamber 2 located adjacent to the insulation layer 3 and an insulating membrane 7 separating them. The first and second cameras 1, 2, are communicated in the lower zone of the same.
    In this preferred embodiment of the invention, the separating insulating membrane 7 is formed by bands of flexible material, this material being preferably a closed cell polyethylene foam.
    As can be seen in Figures 1, 2, 5.1 and 5.2, in this preferred embodiment of the invention, the intake and ejection devices 6 comprise an air intake grill 8, an air exhaust grill 9, a valve of butterfly 10 and control means thereof. In said Figures it is shown that the butterfly valve 10 has a first open position in which the intake grid 8 is communicated with the second chamber 2 and the ejection grill 9 is communicated with the first chamber 1 and, a second closed position in which the intake and expulsion grilles 8, 9, are communicated with each other and the first and second chambers 1, 2, are also communicated in the upper area thereof in a closed circuit.
    Thus, by actuating the control means of the butterfly valve 10, its position is changed between open and closed, thus allowing to control the air flow between the exterior and the chambers.

    As can be seen in Figures 5.1, 5.2, 6.1 and 6.2, in this preferred embodiment of the invention, the control means of the butterfly valve are formed by a handle 11 located on the inner face of the cover breastplate and also said control means have a fixing spring 12 of the position of the butterfly valve.
    In this preferred embodiment of the invention, the intake and ejection devices 6 comprise a cover element thereof formed by sections of aluminum sheet 13 for protection against rain. Said sections of sheet 13 are joined together and have a silicone seal.
    Likewise, as shown in Figures 6.1, 6.2, the intake and ejection devices 6 are arranged subject to a frame 14 whose transverse dimension is equal to the total thickness of the façade at its roof top and its longitudinal dimension is smaller or equal to 1m.
    The frames 14 of adjacent admission and expulsion devices 6 are secured to each other by means of bolting elements and each of them is fixed to the façade breastplate.
    For the resolution of the corners, as shown in Figure 7, in this preferred embodiment of the invention, the ventilation system comprises a corner module formed by a frame 14 whose transverse and longitudinal dimension is equal to the total thickness of the facades that converge in said corner and where the bottom and sides of this corner module comprise a closing plate 16 of the air passage.
    As shown in Figure 4, in this preferred embodiment of the invention, the bands of the separation insulating membrane 7 are fixed at a certain distance from the insulation layer 3 by means of plastic separators 17. The membrane is fixed to them by means of a closure clip 18.
    Said bands of the insulating membrane 7 are connected to each other and to the fastening uprights 5 of the outer layer 4 of the facade by means of joining means formed by an H-profile 19 glued with adhesive, which ensures the tightness between the two chambers.
    The operation of the system is different according to the needs, which depend on the outside temperature of the building. Thus, as shown in Figures 1 and 5.1, when
    5
    10

    twenty
    25

    35
    the outside temperature is higher than the inside temperature of the building, the butterfly valve 10 is operated so that it acquires an open position.
    In this case, the air enters through the intake grid 8 and is introduced into the second chamber 2. The air in contact with the second chamber 2 descends until it reaches the lowest zone through which it passes to the first chamber 1. At reaching the first chamber 1, the air is heated by contact with the outer layer 4 of the façade and begins to rise until it exits outside by the ejection grid 9 located on the outer face of the roof breastplate.
    The movement of air through the chambers is assured thanks to the temperature gradient between the air entering through the intake grille 8 and the one coming out through the ejection grille 9.
    Since the average temperature of the air in contact with the insulation layer 3 is significantly lower than the average air temperature in a ventilation chamber of a conventional ventilated facade, it is possible to reduce the thermal increase inside the building by solar radiation .
    On the other hand, as can be seen in Figures 2 and 5.2, when the outside temperature is lower than the internal temperature of the building, the butterfly valve 10 is activated so that it acquires the closed position, preventing the communication of air between the chambers and the outside.
    In this case, when the valve is closed, a communication is generated at the top of both the first and second chamber 1, 2, allowing the air to circulate in a circular direction between them.
    Thus, the air of the first chamber 1 is heated by being in contact with the outer layer 4 of the facade, and rises by convection until it passes to the second chamber 2 through the upper communicated area.
    In this second chamber 2, the air comes into contact with the insulation layer 3 and yields part of its heat to the interior of the building, so that the air cools and begins to descend through the second chamber 2 until it returns to the first chamber 1 and the cycle starts again.

    The described embodiment is only an example of the present invention, therefore, the specific details, terms and phrases used herein are not to be considered as limiting, but are only to be understood as a basis for the claims and as a representative basis that provides an understandable description as well as sufficient information to the person skilled in the art sufficient information to apply the present invention.
    With ventilation system for ventilated facade of closed joint presented here, important improvements are achieved with respect to the state of the art.
    Thus, a facade is achieved in which the air flow is controlled and with this a correct operation is obtained with the desired results, both in periods of high temperatures, and in periods of low temperatures.
    In addition, since there are two air chambers instead of one, it is possible to separate the air closest to the outermost layer of the building from the layer closest to the interior. Thus, the air next to the outermost layer, which in times of heat acquires high temperatures, is not the one that is in contact with the insulation layer, being the air that enters through the intake grid, and that has a temperature lower than the air next to the outer layer, the one in contact with it.
    Likewise, in cold seasons, thanks to the two chambers, a circular flow is generated that allows the heated air in the first chamber to pass to the second chamber and, when cooled, returns to the first chamber and begins the cycle. In this way, the hot air in the upper zone and the cold in the lower one do not get stuck as if it occurs in conventional ventilated facades.
    It is therefore obtained in a simple way, increases the energy efficiency of the building.
