Arrangement and system for climate control

Technical area This invention concerns an arrangement that makes possible climate control in a room according to claim 1 and a system according to claim 19.

Background An indoor climate arises in the rooms that are present in buildings used for various purposes, for example private homes and public locations such as offices, hotels, schools, shops, factories and similar. It is usually desirable to control the climate in one or several rooms with respect to the temperature and ventilation. Various arrangements and systems that either heat or cool, or both heat and cool, the air in a room are previously known. Various anrangements and systems that make it possible to ventilate the air in a room are also previously known. Each one of these types of arrangement has its own specific field of use, or function, which means that several arrangements are needed in order to satisfy all of the climate needs in a room. It will be expensive to have all of these arrangements. It may be difficult also to find space for all of the arrangements in one room.

Description of the invention One purpose of this invention is to offer an arrangement and a system that make it possible to control the climate in a room with respect to both temperature and ventilation.

This purpose is achieved with an arrangement with the technical distinctive features that are specified in claim 1 and a system with the technical distinctive features that are specified in claim 19.

Detailed description of embodiments This invention concerns an arrangement 1 for climate control, influencing the climate, in a room. The arrangement 1 comprises a heat exchange arrangement 2 that is fed during use of the arrangement with a medium that has been heated or cooled, for the transfer of heat or cooling from the medium to the heat exchange arrangement 2 and onwards to the air in the room. The arrangement 1 comprises also an air supply arrangement 3 that makes possible the supply of air to the room. The air supply arrangement 3 is part of a ventilation system through which air that has been supplied is brought to the room and is allowed to spread out into the room. See Figures 1-4.

One side 2A of the heat exchange arrangement forms the side 1A of the arrangement that faces in towards the room. See Figure 2. The air supply arrangement 3 is arranged on the other side 2B of the heat exchange arrangement. The heat exchange arrangement 2 comprises at least one penetrating opening, a hole, 2.1 through which air from the air supply arrangement 3 can pass from the rear surface 2B of the heat exchange arrangement to the front surface 2A and 1 A of the heat exchange arrangement and the arrangement.

It is appropriate that the heat exchange arrangement 2 comprise several holes 2.1 evenly distributed across the heat exchange arrangement 2. An air distribution arrangement 2.1a, an air nozzle, is located in each hole 2.1. Since the supplied air is spread across the rear surface 2B of the heat exchange arrangement, a certain degree of heating or cooling takes place by the heat exchange arrangement 2 also of the supply air. The supply air entering the room at the front surface 1 A of the arrangement, in the region or at the surface at which the air in the room is heated or cooled by the front surface 2A of the heat exchange arrangement, results in the heated or cooled air in the room being set in motion by the supplied air, and this increases the rate at which the room is heated or cooled. In principle, 100% of the front surface 1A of the arrangement, the front surface 2A of the heat exchange arrangement, is a heated or cooled surface.

The heat exchange arrangement 2 and the air supply arrangement 3 are integrated, fixed united with each other. The air supply arrangement 3 is located above or behind the heat exchange arrangement 2. It is preferable that they be glued to each other, glued to each other and placed in contact with each other, along side sections 2B1 and 3A1 that face towards each other and are comprised within the arrangments 2 and 3, respectively. See Figure 3. The arrangement 1 is a flat panel-shaped construction with a height H that is less than or equal to 50 mm, preferably with a height that is less than or equal to 40 mm, and with a well- defined surface extent.

An arrangement 1 according to the invention can be described also as a panel construction that not only heats or cools but also ventilates the room in the same construction. The arrangement 1 can carry cooling in order to reduce the temperature in the room or it can carry heat in order to increase the temperature.

The heat exchange arrangement

The heat exchange arrangement 2 comprises an inlet 2.2 for the introduction of the medium into the heat exchange arrangement 2, an outlet 2.3 for withdrawal of the medium from the heat exchange arrangement and passageways 2.4, pathways, in and through the heat exchange arrangement 2, through which the medium is transported through the heat exchange arrangement 2 from the inlet 2.2 to the outlet 2.3.

The heat exchange arrangement 2 is a type of flat heat exchanger with a relatively large surface extent. The heat exchange arrangement 2 comprises two flat sheets 2.5 and 2.6 of material with a surface extent, which sheets are arranged parallel relative to each other and are tightly united with each other along their edges 2.7 and 2.8 and at parts 2.9 of the surfaces 2.10 and 2.11 of the sheets of material that are turned towards and face each other, which creates passageways 2.4 between the two sheets 2.5 and 2.6 of material and between, around, the parts 2.9 in which, through which, the medium is transported, is caused to pass, through the heat exchange arrangement 2. See Figure 4.

This design of the heat exchange arrangement 2 results in the medium being evenly spread across the complete surface 2A, which results in a high power of heating or cooling of the arrangement 1. Due to the high power of heating or cooling, it is necessary to cover only approximately 40-50% of a surface of the room in order to obtain satisfactory heating and cooling, corresponding to other heating and cooling arrangements. This provides greater opportunities to adapt the room to other requirements during the installation of, for example, illumination and fire protection.

The parts 2.9 have the form of points, principally circular, and are evenly distributed across the heat exchange arrangement 2, across the sheets 2.5 and 2.6 of material, such that the passageways 2.4 form a lattice across the heat exchange arrangement 2. The parts 2.9 are evenly distributed across the sheets 2.5 and 2.6 of material in order to offer an opportunity for the medium to flow evenly through the heat exchange a angement 2 and an even distribution of the heat or cooling.

One of the sheets 2.5 of material is plane. The other sheet 2.6 of material comes into contact with the plane sheet 2.5 of material at the parts 2.9 and is united with it there. The plane sheet 2.5 of material constitutes a side 2A of the heat exchange arrangement 2 that faces in towards the room, a side A that faces in towards the room, a front surface, of the arrangement 1. See Figure 4. At least one of the parts 2.9 in the heat exchange arrangement 2 comprises a hole 2.1 that passes through the heat exchange arrangement 2, from the rear surface 2B of the heat exchange arrangement to its front surface 2A. This hole 2.1 is the same hole as the hole 2.1 that has been previously mentioned and that through which air from the air supply arrangement 3 can pass, from the rear surface 2B of the heat exchange arrangement to the front surface 2A of the heat exchange anrangement, and of the arrangement, 1A. It is appropriate that the heat exchange arrangement 2 comprise several such holes 2.1 evenly distributed across the heat exchange arrangement 2. An air distribution arrangement 2.1a is located in each hole 2.1.

The heat exchange arrangement 2 is principally manufactured from a polymer material. There may be other parts or fittings that, for example, make possible attachment to other units, that reinforce certain parts, or that have some other function, which parts are manufactured from some other material than a polymer material.

The polymer material is of ABS type, a co-polymer with different amounts of acrylonitrile, butadiene and styrene monomers. ABS is a material of low weight, high strength, good shape-holding properties and low cost of production. ABS has high impact strength, surface hardness and surface finish; it resists acids, alkaline solutions, alcohol, grease, oil, salt solutions and saturated hydrocarbons. ABS also gives a significantly lower condensation temperature than other available materials, and this gives a higher heating and cooling power. This choice of material means that the heat exchange arrangement 2 can be fully recycled.

The sheets 2.5 and 2.5 of material of the heat exchange arrangement are heated during the manufacture of the heat exchange arrangement 2, placed against each other and pressed against each other at the part 2.9 such that the material in the sheets becomes bonded to each other and cooled, solidifies, in a joint at the part 2.9. The order in which these operations are performed does not need to be the order described here. The pressure force can arise through mechanical pressure on at least one sheet of material in a direction towards the second sheet of material or through the creation of negative pressure between the sheets 2.5 and 2.6 of material and at a predetermined locked relative positioning of the sheets.

The design of the heat exchange arrangement, with respect to both its construction and choice of material, results in it being sound-absorbing.

The air supply arrangement

The air supply arrangement 3 comprises an air distribution arrangement 3.1 arranged of the side 1B of the arrangement that faces away from the room, on the rear surface 2B of the heat exchange arrangement, which air distribution arrangement is fed with air from a source of air and spreads and distributes the air across the rear surface 2B of the heat exchange arrangement. See Figures 1 and 5.

The air supply arrangement 3 comprises a coupling arrangement 3.2 attached to, or constituting a part of, the air distribution arrangement 3.1 that makes it possible to couple the arrangement 1, the air supply arrangement 3, the air distribution arrangement 3.1, to an air transport arrangement 3.3 that is connected to the source of air. The air distribution arrangement 3.1 comprises a hood 3.4 that has one open side 3.4A that is directed towards and covers the rear surface 2B of the heat exchange arrangement. See Figure 5.

The air distribution arrangement 3.1 , the hood 3.4, comprises an edge part 3A1 that is fixed attached on the side 3.1 A or 3.4A that faces towards the heat exchange arrangement 2 to the rear surface 2B of the heat exchange arrangement, to the edge part 2B1 of the heat exchange arrangement.

Also the air supply arrangement 3, the air distribution arrangement 3.1, is principally manufactured from a polymer material. There may be other parts or fittings that, for example, make possible attachment to other units, that reinforce certain parts, or that have some other function, which parts are manufactured from some other material than a polymer material. This choice of material means that the air supply arrangement 3 can be fully recycled.

The surface layer

An arrangement 1 according to the invention comprises a surface layer 4 arranged across the side 1A of the arrangement that faces in towards the room, the front surface of the arrangement Since the front surface 2A of the heat exchange arrangement is that part that constitutes the front surface 1A of the arrangement, it is the heat exchange arrangement 2 that is covered by the surface layer 4. The surface layer 4 consists of a textile, appropriately manufactured from polyester, recycled polyester, which has a very low impact on the environment. The textile may have a neutral light colour, and it is possible to use also other colours. It is even possible to use screen- printed textile. Mould does not grow on the material, and the material is odour-free. It does not emit gases, provoke allergies or irritate skin or air passages. Further, it is easy to keep clean. Normal agents for textile cleaning that are available in shops are recommended for removing stains. This choice of material means that the surface layer 4 can be fully recycled.

Other considerations It is appropriate that an arrangement 1 according to the invention use water as the medium that is heated or cooled and subsequently transported through the heat exchange arrangement 2. The fact that the arrangement 1 , the system, is a hydronic system gives the room an even and comfortable temperature, with no air draughts at all.

It is appropriate that the air transport arrangement 3 be connected to a filter, an air filter, for example an allergy filter 5. This makes it possible to use an arrangement according to the invention in a room of the type known as a "clean room".

The size of the arrangement 1 is adapted for mounting in existing horizontally arranged mounting arrangements for currently existing interior ceiling structures that comprise sectioned frameworks, onto and into which are placed, laid, sheets of material, and where the sheets of material normally have sound-absorbing functions. It is possible with this arrangement 1 to construct a heating and cooling interior ceiling that can replace or supplement existing ceilings, interior ceilings, rapidly, simply and in a cost-effective manner. The fact that the parts and fittings of the arrangement 1 are manufactured from polymer materials results in the arrangement 1 being light. This, in turn, results in the installation of one or several arrangements 1 being easy, rapid T's" missing in source] and cost-effective. See Figure 6.

An arrangement 1 as the one described above is intended to be mounted horizontally at a ceiling 6. The arrangement 1 can be mounted also in, or it may comprise, similar or totally different attachment arrangements that make it possible to mount the arrangement 1 in a vertical direction, mounted, for example, at a wall 7. See Figure 7.

The arrangement 1 is, since it comprises relatively flat parts, a flat construction when considered overall, with a height H that is less than or equal to 50 mm, preferably with a height that is less than or equal to 40 mm, and with a well-defined surface extent, and with a length. An arrangement 1 may be adapted to an existing interior ceiling with supports of the type Armstrong Trulock T24 or equivalent, and it is then manufactured with dimensions of 600 x 1200 mm. The height H is measured from the front surface 1A of the arrangement to the coupling arrangement 3.2 of the air supply arrangement.

The embodiment of an arrangement 1 according to the invention shown in Figure 2 comprises an illumination unit 8 arranged to spread light either across or from, or both across and from, the front surface 1 A of the arrangement. The illumination unit 8, or a part of it, a source of light, is arranged in a penetrating opening 8.1 through the heat exchange arrangement 2 such that also the front surface 1A of the arrangement makes possible the illumination of the room. The illumination opening 8.1 may be one of the holes 2.1 through which it is intended that air be transported from the rear surface 2B of the heat exchange arrangement 2 to its front surface 2A, or it may be a specially constructed opening for this purpose. An illumination opening 8.1 is removed from one of the parts 2.9 previously described. The illumination unit 8 comprises parts necessary for power supply, the creation of light, and the spreading of light.

An arrangement 1 according to the invention comprises also a sprinkler system 9 or a part of a sprinkler system 9. A part 9.1 of a sprinkler system 9, a nozzle, a mouthpiece, is shown in Figure 2 arranged in at least one penetrating opening 9.2 through the heat exchange arrangement 2 in order to spread water or another fire-extinguishing medium in the room from the side 1A of the arrangement that faces in towards the room. The sprinkler opening, the nozzle opening, can be one of the holes 2.1 through which it is intended that air is to be transported from the rear surface 2B of the heat exchange arrangement to its front surface 2A, one of the holes 2.10 through which it is intended that an illumination unit be arranged, or a specially constructed opening 9.2 for this purpose. The sprinkler opening 9.2 is removed from one of the parts 2.9 previously described. One or several of the nozzles 9.1 may be arranged also in other ways at an arrangement 1 according to the invention, in a manner, for example, that results in a more direct access of the medium, the water, in the heat exchange arrangement 2. The sprinkler system 9 comprises parts necessary for the supply of medium, the supply of water, pressurisation, spreading, activation and control. It is appropriate that the sprinkler system be fed with the medium, the water, that is used in the heat exchange arrangement 2. See Figure 2.

Thus, an arrangement 1 according to the invention can, at most, heat and cool, ventilate, illuminate and sprinkle the room, in one and the same construction. This gives further major possibilities of adapting the room to also other needs, with the installation of different functions in one room, not only arrangements that affect the climate.

All of the coupling parts of the arrangement, for not only medium, but also air and electricity, are located at the rear side 1 B of the arrangement, which results in an invisible installation of the complete arrangement 1 when the arrangement 1 is mounted, installed, and in place.

The invention concerns also a system 10 for climate control, influencing the climate, in a room in which at least two arrangements 1 are coupled with respect to at least one of the supply of medium, the withdrawal of medium and the supply of air. The system 10 is also coupled in a suitable manner with respect to power supply to one or several illumination units 8. See Figure 8. The arrangement 1 , and also coupled arrangements 1 that form a system 10, is silent and sound-absorbing, and creates a pleasant acoustic environment in the room. This is particularly suitable for noisy environments and for rooms that have requirements for a particularly good sound environment placed on them. Thus the arrangement 1 affects not only temperature and air quality but also the experience of sound in a room.

The low weight of the arrangement, and thus of the system, means that it is possible to install the arrangement or system in an existing interior ceiling by exchanging several of the original ceiling panels, normally sound-absorbing panels, for several arrangements 1 according to the invention, or for a complete system 10. Each arrangement 1 is very thin and light and is coupled to a second arrangement 1 with the aid of a coupling system comprising jointed tubes and joints, for the supply of medium and air. The installation is simple - tubes are needed only between the arrangements 1. The system 10 can be mounted where necessary at a wall that, due to the distribution of heat and cooling and due to natural thermodynamics in a room, has a higher power.

The arrangement 1, the system 10, requires no maintenance after installation. Constructions and designs mentioned in the description of the invention may be freely combined to give the best conceivable arrangement or system for the purpose.

This description of the invention is not to be seen as a limitation: it is to be used as a guide to full understanding of the invention. Adaptations of different parts relative to other component active parts, the choice of materials, adaptations of size, adjustments in form, replacement of parts and fittings and anything else that is obvious or that is easy for one skilled in the arts to envisage may be made within the innovative concept of the invention. Different designs of different parts, and different parts described for different embodiments may be freely combined within the innovative concept of the invention, provided that the desired function is obtained.
