    专利说明:

    The present invention relates to a glass unit, and more particularly to a glass unit for use in a window in an outer wall or as the outer wall itself, in a property.
    In countries with fluctuating temperatures during the year, and especially in countries where there is a great need for heating in the winter, the design of glass units has primarily been designed to be able to design these so that they do not emit too much heat, ie. reduces heat radiation.
    As glass units have been made larger, and in many cases also make up the majority of exterior walls, more and more solar radiation has been obtained in the properties, which during the hot seasons is a cooling need, and air conditioning systems are then installed for this. In larger glass units, and also in office environments where there are many people and machines that create heat, the cooling needs thus increase during the hot season, and many installed air-conditioning systems are not dimensioned to be able to handle excessive temperatures. The object of the present invention is therefore to provide a new glass unit which is designed to attenuate heat radiation through the glass unit, without significantly encroaching on the light transmittance. I / | an still want to get in the daylight, and be able to look unhindered.
    In order to reduce the heat radiation, many attempts have been made to apply a coating to the inside of the inner glass, possibly in the form of a solar film applied to the inside of the glass. This reduces some of the radiated solar heat, but above all the radiated light. The disadvantage of such a solar film, however, is that it also reduces the possibility of looking to the same degree. I / | an has also developed glass which is already coated during manufacture with an oxide layer on one side of the glass to reduce solar radiation. Such an oxide layer can also be colored to give the glass a certain color shade when viewed from a distance, which can be an effect one wishes to achieve in properties where the entire façade consists mainly of glass. Such an oxide layer is arranged on one side of the glass, and then normally on the inner side of the outer glass at glass units composed of several glass panes.
    In order to increase the insulating capacity of the glass units, both in terms of heat radiation and heat radiation, insulating panes are now usually used, with two or three glass panes joined in a gas-tight metal frame and with a gas, usually a noble gas introduced into the space between the various glass layers. In the case of such composite insulating glass units, a glass with an oxide coating arranged on the side facing inwards into the property has then been selected for the glass facing outwards. The other glasses in the glass unit usually lack coating. The cost of a glass with an oxide layer is higher and a general opinion is that several oxide layers would not give any better values in terms of heat radiation or heat radiation.
    The inventor of the present invention has noted that the heat radiation can be further reduced by arranging an oxide layer on a further glass in the composite glass unit. The object of the invention is achieved by the inward-facing glass is also provided with a coating.
    According to a preferred embodiment of the invention, the coatings consist of oxide layers formed in connection with the manufacture of the glasses.
    According to a further preferred embodiment of the invention, the oxide layer on the outwardly facing glass is of the same material as the oxide layer on the inwardly facing glass.
    According to yet another preferred embodiment of the invention, the coating on the inwardly facing glass is arranged on the outwardly facing side of the inner glass. According to a further preferred embodiment of the invention, the glass unit with the outward-facing glass and the inward-facing glass constitutes an insulating glass unit.
    According to yet another preferred embodiment of the invention, the insulating glass unit is designed as an insulating glass unit with three glasses.
    According to a further preferred embodiment of the invention, the glass between the outwardly facing glass and the inwardly facing glass is also provided with a coating, preferably on its inwardly facing side.
    The invention will now be described in more detail in the form of a non-limiting exemplary embodiment, illustrated in the accompanying drawing figures, in which Fig. 1 shows a first exemplary embodiment of a glass unit according to the invention with a coating on the inside of the outwardly facing glass and on the outwardly facing the side of the inward-facing glass in an insulating glass unit with three glasses, and Fig. 2 shows a corresponding view where the middle glass is also provided with a coating on its inward-facing side.
    Fig. 1 shows a window portion 1 according to the invention inserted in a window frame 2. In this example the window portion 1 is an insulating glass unit comprising a first glass 3 facing the outside of the property in which it is mounted, a second glass 4 facing the inside of the property in which it is mounted, and a third glass 5 located between the first 3 and second 4 glasses.
    The three glasses 3, 4, 5 are joined in a known manner with e.g. an adhesive and a gas-tight metal frame 6, 7 between the respective glasses, and where the three glasses are separated by a space filled with gas. The gas is preferably a noble gas, such as for example Argon which is commonly used in such contexts.
    The first or outer glass 3 is provided on its inside, as is known, with a coating 8, more specifically a heat radiation-damping coating. This coating 8 is preferably an oxide coating created on the inside of the glass most often in connection with its manufacture. The oxide coating is preferably a metal oxide coating. 150014EN In the embodiment shown, the second or inner glass 4 is also provided with a coating 9, of the same kind as the coating 8 on the first glass 3. The coating 9 on the inner glass 4, on the other hand, is turned outwards, i.e. from the inside of the property and towards the coating 8 on the first glass 3.
    In the embodiment shown in Fig. 2, the third or intermediate glass 5 is also provided with a coating 10 of the same kind as the coatings 8 and 9 on the outer and inner glasses 3resp. 4. Preferably, the coating 10 on the intermediate glass 5 is arranged on its inside, i.e. against the inner glass 4 and its coating 9, but may also be arranged on the opposite side of the glass 5. The coating 10 is suitably also of the same material as the coatings 8 and 9, and also produced in connection with the manufacture of the glass itself.
    Glass units according to the invention have been able to achieve very good results in terms of inlet of heat radiation without adversely affecting the attenuation of heat radiation or light transmission, and can thus reduce heat radiation so that the requirements for cooling the indoor air by means of air conditioning systems can be reduced. .
    It has also been calculated that the cost of replacing existing windows or glass units is lower than the cost of increasing the capacity of existing air-conditioning systems to achieve corresponding indoor temperatures.
    In the description above it has been stated that the oxide coatings applied to the glasses are of the same kind, but it is obvious that they can also be different, especially in the case where one of them naturally or created gives a color shade. 150014SE
