    Background of the invention The invention relates to a flattening element for cooling and / or heating of room air, especially in connection with submerged roofs, which flattening element comprises a canister body, which is intended to be placed inside the submerged roof or another canister space substantially in the horizontal plane and horizontally. separated by a suction chamber and a pressure chamber, the suction chamber of the suction chamber and the exhaust tip of the pressure chamber and a fresh air unit; a heat exchanger and at least one flap adjoining the suction and pressure chambers, which is located inside the capsule body; and a grid arrangement, which connects to the suction and exhaust openings.
    The flattening elements are roughly divided into two main groups: encapsulated elements and non-encapsulated elements. Encapsulated elements are intended for visible installation and non-encapsulated elements inside a sunken roof or casing. The invention relates in particular to such an unencapsulated flat element, the capsule body of which is hidden inside the structures of the building. Such a technical solution is common, for example, when cooling and / or heating hotel rooms.
    There is already a solution on the market which represents the state of the art, whose canister body consists in a set of several modules, so that on the pressure side of the flat unit towards the room space the pressure chamber is fixed and on the suction side on the opposite side of the flat unit a water chamber is fixed away from the room space. , the fresh air unit being located on one side of the exhaust chamber. In the room space, this unit of apparatus is covered inside the sunken ceiling, whereby, for example, in a hotel room, it is covered in the ceiling in the room's hall. Room air is sucked into the suction chamber, via the grille in the roof of the drum and cooled or heated air is biased into the room via a second grid arranged in the end surface above the drum.
    This flat element that is used nowadays is large, expensive and clumsy. In this solution, the element also always sucks mixed air, whereby the logarithmic temperature difference between element and air is small. A slight temperature difference in turn leads to circulation of a large amount of air, which results in an increase in the sound level of the element and an increase in energy consumption.
    Summary of the invention The object of the invention is to develop the flattening element described at the outset, so that the above-mentioned problems can be solved. This object is achieved with a flat element according to the invention, which is mainly characterized by the fact that the flat is placed in the rear part of the capsule body; the space in front of the surface is divided substantially in the horizontal direction into two spaces located one above the other, the space in the lower part of the capsule body forming a suction chamber and the space above it in the upper part of the capsule body forming a pressure chamber; the heat exchanger is located on the surface of the suction chamber substantially halfway between the suction chamber and the suction opening; and that an intermediate wall between the suction chamber and the pressure chamber is bent upwards next to the heat exchanger on [Dada sides thereof to provide a sound-damping trap on the side of the pressure chamber.
    Thanks to the construction according to the invention, a large logarithmic temperature difference is achieved between the liquid circulating in the element and the air coming to the element. The flue is placed as far away from the exhaust opening as possible, whereby the suction and pressure chambers function in real time as sound damping chambers without these having to be arranged separately. When the heat exchanger is placed in the suction chamber, and not too far from the suction opening, the flatness creates an even paraploid velocity profile over the heat exchanger. The heat exchanger and an advantageous supply air filter to be placed in front of it also function for their own part as the extra side muffler on the suction side in addition to the long suction chamber itself. With the advantageous bending upwards of the intermediate wall between the suction chamber and the pressure chamber, a sound-damping trap is obtained on the side of the pressure chamber and space for the heat exchanger located in the suction chamber is correspondingly set.
    Since the flow and heating technical solutions make it possible to make the suction and pressure channels shallower without causing an increase in the sound level, the flux in fact now determines the height of the entire flattening element, whereby the construction can be made very low. This, together with the simple mechanics, enables an approximately 50% weight reduction compared to kanda solutions. The simple and clear construction Is it also possible to Ora the flat element a lot of pine without water and air varnish.
    Preferably, the grid arrangement therefor is formed as a whole, which is divided in the horizontal direction functionally into two parts, its lower part connecting to the suction chamber of the suction chamber and the lower part to the exhaust opening of the pressure chamber. In this case, the lower part on the side of the suction opening has horizontal lattice slats, which are directed obliquely downwards, and the upper part on the side of the exhaust opening has horizontal lattice slats, which are directed obliquely upwards. The control of the air trays is further made more efficient when the grating arrangement therefor is designed for the vertical cross-section convexly curved towards the room space. Figure The invention is now explained in more detail with the aid of an advantageous exemplary embodiment with reference to the accompanying drawings, in which: as a cross section and installed on site at the place of use; figure 2 shows a flat element according to figure 1 seen from above; and figure 3 shows a lattice assembly seen in figures 1 and 2 shown separately and seen from the front.
    Detailed description of the invention With reference to the drawings, they show a flat element 1 according to the invention for cooling and / or heating of room air, especially in connection with sunken ceilings LC.
    The flattening element 1 comprises a canister frame 2, which is intended to be placed inside a recessed ceiling LC of a room space R, more precisely defined in a space A formed by the recessed ceiling LC, the actual ceiling C and the cradles W or inside another corresponding canister space substantially in the horizontal plane. This canister body 2 has Than separated from each other, but attached to the structure belonging to a suction chamber 3 and a pressure chamber 4, the suction chamber suction opening 5 and the pressure chamber exhaust outlet 6, and a fresh air unit 7. In the case of the canister body 2, suction is provided in each case. the pressure chambers 3, 4 connecting flats 8 and a heat exchanger 9 and a supply air filter 10. A grid arrangement 11 in turn connects to the suction and exhaust openings 5, 6.
    The essential thing in this construction is that the flaps 8 are placed in the rear part of the capsule body 2, the space in front of the flaps 8 being divided substantially in the horizontal direction into two superimposed spaces, the space in the lower part of the capsule body 2 forming the suction chamber 3 and the space above it in the capsule body 2 upper part forms the pressure chamber 4. The floats 8 function as a "joint" which separates the suction and pressure side in the rear end of the nnellan cradle 12 between the suction chamber 3 and the pressure chamber 4. 2110121EN 4 In connection with such a construction, where the suction and pressure the pressure chamber 3, 4 are coated on top of each other, it is possible and sensible to design the grid arrangement 11 into a whole which is divided in the horizontal direction functionally into two parts, so that its lower part 13 connects to the suction chamber 5 of the suction chamber and upper part 14 to the exhaust chamber of the pressure chamber. 6. The grid arrangement 11 has on the suction opening 5 sides in the lower part 13 horizontal grid slats clays 13a, which are directed obliquely downwards and on the side of the exhaust opening 6 in the upper part 14 horizontal lattice slats 14a, which are directed obliquely upwards. This grid arrangement 11 is additionally formed 10 to the vertical cross-section convexly curved towards the space R. Salunda, the route for air which is sucked up Than the space R is clearly separated from the air which is biased towards the space R.
    The heat exchanger 9 is located on the surface of the suction chamber 3 substantially halfway between the suction chamber 3 and the suction opening 5, and at the same time the intermediate wall 12 between the suction chamber 3 and the pressure jug chamber 4 is bent upwards next to the heat exchanger 9 on both sides thereof. to simultaneously place the heat exchanger in a vertical layer in the suction chamber 3.
    The supply air filter 10 is placed in an inclined position immediately behind the grid structure 11. Its cleaning is simple when the grid structure 11 is suitably fixed with hinges to open it.
    The fresh air unit 7 is placed in the central region of the rear cradle of the capsule body 2, so that inside the capsule body 2 it extends between the flaps 8 to their suction side. When the unit 7 is coated in this way, only 25 single-dimensional flat elements are needed.
    In addition, in the central region of the rear cradle of the capsule body 2, a condensate water outlet assembly 15 is located. This also fits well with the single-element design of the flattening element, since the unit 15 can be ruddered in equal choice either to the right or to the left. The flat element can be freely condensing and the condensed water can be diverted either by gravity or by a pump.
    The above description of the invention is only intended to ash the basic idea according to the invention. One skilled in the art can thus modify its details within the scope of the appended claims.
