Description

  The present invention relates to a replacement ventilation apparatus including a filter for replacing a room with ventilation and filtering supplied supply air.

  The principle of displacement ventilation is to introduce air into the room through one or more air supply means located in a low place. The speed of the air passing through the air supply surface of the air supply means is set low, thereby causing a slight turbulence.

  The temperature of the air supplied from the air supply means is somewhat lower than the temperature of the room air, and as a result, after being exhausted from the air supply means, the supply air flows over the floor, rises, Is filled with clean air from below. The air already present in the room somewhat hotter than the air supplied from the air supply means contains, for example, particles and possibly undesirable gas compositions, and this hot air is pushed over clean air. It is discharged and discharged to the outside through the exhaust means usually located at a high place in the room.

  In a conventional replacement ventilation air supply means to which supply air is supplied from a central ventilation system having an air filter, the house including this means has a conical air distributor and a transmission wall through which the air is supplied. The supply air flows at low speed into the room where it is ventilated.

  This known air supply means for replacement ventilation functions well, but has the disadvantage that its structure limits its adaptability to the room in which it is installed.

  It is an object of the present invention to provide a replacement ventilation device that is more adaptable than conventional devices.

  This purpose includes a connection to the supply air conduit of the central air supply system and a filter for filtering the supplied air in order to introduce temperature-controlled clean air to replace room air An apparatus for evacuating a room, further comprising a filter-housing module having a filter for filtering air supplied through an air supply conduit connection, and a rear part for supporting a plurality of support plates A modular support body configured, wherein at least one of the support plates is connected to the rear for supporting the filter-housing module, and the filter-housing module comprises a replaceable sealed module This is achieved by a replacement ventilator characterized in that

  The present invention provides a replacement ventilation device that can be easily and efficiently applied to different construction conditions and that is easy to assemble and maintain as well as manufactured. Furthermore, the present invention provides a wide range of modular ventilation equipment, which meets and meets all conditions of a particular room with a limited number of basic modules. Many differently shaped air supply means can be formed that are adapted to achieve the desired effect.

  The replacement ventilation apparatus of the present invention preferably includes a circulation module for pre-filtering air circulating in the room.

  The replacement ventilation apparatus of the present invention preferably includes a fan unit for circulating air. Especially in combination with the above circulation module, the circulating air is filtered before being taken into the fan unit, which is quite effective. In particular, this combination also ensures that the circulating air filter is adapted to the condition of the particular room and the contaminants that are expected to be scattered in the room, while the filter-housing module itself is in the condition of the supply air. Fits virtually reliably.

  By arranging a silencer for the inlet and exhaust of the fan unit, noise can be significantly reduced.

  By supporting the fan unit inside the silencer block, it is possible to effectively prevent vibration from the fan unit from being transmitted as vibration sound to the frame of the apparatus and further to the building part. The silencer block is preferably connected to the inlet-side silencer, particularly preferably forms part of the inlet-side silencer, thereby enhancing the silencer function and the possibility of noise leakage Can be suppressed.

  The silencer is advantageously made from a synthetic foam with open cells and an airtight surface layer on the outside. As a result, a very good silencing effect can be obtained. The air channels inside the silencer members are not coated with an airtight layer, but the open cells of the foam are open towards these channels.

  An apparatus having a modular body consisting of a rear part (such as a rear plate) and a support plate fixed at right angles thereto facilitates the manufacture and assembly of the air supply means of the present invention. In particular, in some cases, the support plate may have a structure in which a short tubular portion is provided, and this tubular portion supports the silencer and serves as a conduit connecting the silencer. Adjacent to the silencer located on both sides of the.

  Further advantages of the present invention will become apparent from the following detailed description.

  The replacement ventilation device 1 shown in FIG. 1 is connected to an air support conduit 2 belonging to a central air support system. The air support conduit 2 is connected to the filter-housing module 3 via its upper air supply connection 4, which has a filter on its front face.

  In addition to the filter housing module, the replacement ventilation device 1 of the present invention includes a circulation module 5 provided with a circulation air filter. This circulation module 5 is located on two circulation conduits 7, which are located on the inlet-side silencer 8 and connected to a block that supports the fan unit 6. Absorbs intake noise generated during operation.

  The exhaust from the fan unit 6 includes a first part including a first connection part 10 for connection to the fan unit and a second part including a second connection part 11 for connection to the filter housing module 3. Suction is performed via the exhaust-side silencers 9a and 9b.

  The circulating air from the fan unit is thus guided through the conduit 9a of the first part of the exhaust silencer and further to the second part of the exhaust silencer, where the air flow is substantially And is guided to the filter-housing module 3 via the end opposite to the end of the supply air connection 4.

  The replacement ventilator 1 is composed of a rear portion 12 made of a plate bent at 90 degrees to fit the corner of the room. A number of support plates 13, 14, 15 and 16 can be fastened to the rear part 12 in a snap-type manner or in a way that these support plates are located substantially perpendicular to the two main parts of the rear part 12. . The support plate 13-16 supports an intake connection to the circulation module 5 and the intake-side silencer 8, constitutes a boundary between the fan unit block and the exhaust-side silencer, and further exhausts the silencer. It forms the boundary between the two parts 9a, 9b of the machine and at the same time supports the connection of the filter-housing module 3.

  The bottom support plate 16 located at the bottom may be arranged to support a control device included in the apparatus.

  A cover 17 made of a plate with holes for allowing air to pass through is arranged to cover the filter-housing module 3 and the circulation module 5. A rounded concave cap 18 is disposed at the bottom of the replacement ventilation device 1. The fan unit block is covered with a lid 19 provided with an inner sound insulating material (not shown).

  The replacement ventilation apparatus 1 is designed to be very small while having the above-described structure, and thus can include several functions in a limited area while maintaining high adaptability and modular structure.

  When the functions of the filter-housing module 3 and the circulation module 5 are used up, the cover 17 covering the air supply conduit 2 is removed, the intake port and the exhaust port are sealed, and the filter is covered with a cover sheet or the like. After covering the front, it can be easily replaced by removing the filter-housing module 3 and the circulation module 5 and installing a new module.

  FIG. 2 shows an enlarged view of the filter-housing module 3 with the connections 4 and 20. The filter-housing module 3 is designed in the form of a sealed bag and is obtained by sealingly joining two identical molds, preferably made of a plastic material such as polycarbonate, to each other at its flange. Reference numeral 21 denotes three filter parts having a filter inserted hermetically inside the filter-housing module 3.
