    Equipment for ventilation of buildings
    The present invention relates to equipment for ventilating buildings, which equipment according to the preamble of claim 1 comprises at least one and preferably at least two heat exchange units which exchange energy between the intake air and the exhaust air from the building respectively, which equipment is controlled electronically and centrally. Such equipment is used to improve the indoor climate in buildings. For example, poor indoor climate may be due to high humidity, too high CO2 content, too high radon content and too high content of other gases and pollutants. In addition, pollen and fungal spores can also give rise to poor indoor climate. Therefore, a frequent venting is recommended, which has traditionally been done by opening certain windows and doors and windows during a period whereby part of the indoor air is replaced with outdoor air. There are some drawbacks to this kind of venting. When the outside temperature deviates from the indoor temperature, a loss of heat or cold will occur. If the humidity is high outside, it will often not be possible to reduce the humidity of the indoor air, on the contrary. In addition, when the wind is blowing, features can occur which can lead to discomfort and smashing doors and windows.
    It is instead possible to use fans, which will however also lose heat or cold when the outside temperature differs from the indoor temperature.
    A solution to the problem of poor indoor climate is proposed by Genvex, which produces and sells ventilation systems with air-to-air heat exchangers. A Genvex system is expensive to buy and expensive and complicated to install, especially since a comprehensive piping is required. In use, the plant has a relatively high energy consumption, and frequent cleaning is required to avoid, among other things, dust and dirt in the pipes, where, for example, mold can grow, which will then lead to poor indoor climate.
    DK 2018 70630 A1
    It is an object of the invention to provide improvements over the prior art systems so that efficient ventilation of a building can be ensured in an easier and cheaper way.
    According to the characterizing part of claim 1, the equipment for ventilating buildings is characterized in that the equipment comprises at least one interior unit containing a first flow duct with an associated blower and a second flow duct with an associated blower, wherein the first blower blows in the air, and the other blower sucks out the air, which two blowers can be controlled separately. Such a unit simply ensures ventilation of separate rooms in a building and is at the same time suitable for ensuring air transport through, for example, corridors where one or more doors are closed. There is also a great advantage in the fact that there is no need to use pipes in the building, which allows the installation of the ventilation system can be done very cheaply and quickly.
    According to a preferred embodiment of the invention, the equipment is characterized in that the interior unit is provided with covers which can be used to direct the air in the desired direction into and out of the unit. This provides an opportunity for efficient air exchange in the separate rooms, and the units can thus help ensure good ventilation throughout the building.
    In an advantageous design of the equipment, the flow channels can be designed at least in the inlet side with narrowing towards outlet, so that the inlet takes place over a relatively small area. This makes it possible to almost push the supply air into the room, and this design also ensures some noise reduction.
    In the preferred embodiment, the flow channels are provided
    DK 2018 70630 A1 noise canceling material. This reduces the noise from fans and flowing air, and at the same time reduces the possibility of transmitting sound from room to room through the ventilation unit.
    According to an advantageous embodiment of the invention, the equipment for ventilating buildings is characterized in that the heat exchanger unit is formed with a thin metal plate heat exchanger part which is placed directly in an enclosing insulation which acts both to maintain the exchanger part and to insulate insulation. In this way, a good heat exchange is ensured in a structure that is easy and inexpensive to manufacture and is very compact.
    According to the invention, recesses are provided in the enclosing insulation to retain the heat exchanger part. This ensures a good holding of the unit when mounted.
    It is advantageous if the insulating material is also used to hold one or more fans. This is also a way to ensure a cheap construction.
    According to a preferred embodiment, the apparatus is characterized in that the heat exchanger portion is formed of alternately bent and flat plates, the bent plates being provided at both ends with an upward bend of about half the width and a downward bend of about half the width, the upward and downward bends, respectively, are placed diagonally opposite each other. These features also help ensure a simple and inexpensive construction.
    In an advantageous embodiment, the insulation is divided into sections, preferably longitudinally, and it, together with the heat exchanger part, can be removed from the wall and the insulation can be separated so that access to the heat exchanger part for cleaning thereof is provided.
    DK 2018 70630 A1
    It is preferable that the heat exchange unit be placed in an outer wall so that it does not take up space inside or outside the housing, but when an increased heat exchange effect is possible, it is possible to extend the heat exchange unit longer than the wall thickness.
    It is an important feature of the invention that guards located at the suction and exhaust side, of the interior unit and at the exhaust side of the heat exchanger unit can be used to help control air flow both in individual rooms and throughout the building.
    The invention will be explained in more detail below with reference to the drawing, in which

    FIG. 13 shows the unit provided with noise insulating material.
    In FIG. 1 shows a plant according to the invention for improving the indoor climate in
    DK 2018 70630 A1 a residential building. The building shown in the southern part comprises a kitchen / dining room 1, a living room 2, two rooms 3 and 4, a bedroom 5, a toilet / bath 6, an entrance / utility room 7 on the northern part and a hallway 8 that connecting the southern and northern parts of the house. The heat exchanger 9, which is located to the left of the drawing (the southern part of the building), takes the fresh air through open corridors and spaces and out through the heat exchanger 9, which is located in the northern part of the building, which in this example also has a fan in the form of a solo unit 38 in the bathroom 6, and extraction can take place directly in the kitchen / living room 1 via hood. Separate rooms 3-5 are provided with fans 25 in the form of indoor units 25, which can be adjusted to the current need, to ensure ventilation of all the rooms where air exchange is desired to increase the ventilation effect. In addition, the interior units 25 function to contribute to the overall flow of air through the building, and the support units 25a, which are of the same design as the interior units 25 and located at the end of the hallway 8, serve as the primary function of contributing to the air flow through the housing. The ventilation can be controlled both manually and automatically. For example, manual operation can be done via a traditional remote control or an application on a smartphone if you feel a need to change the function. The control can also be automated, so that ventilation is automatically controlled depending on, for example, indoor air temperature, humidity percentage, CO2 content, O2 content, particle content, radon content and the content of various organic compounds such as solvents.
    In FIG. 2 shows the system where air is blown in and out simultaneously through heat exchanger 9 in the outer walls. Here, the support unit units 25a function both to blow air into and suck air out of the shown passage 8. The unit unit 25a with support function is thus the extension arm of the switch units 9 and moves air inside the building.
    DK 2018 70630 A1
    FIG. 3 shows the plant, where there is mainly a flow of air through the building (from north to south). Here, the air passes through the heat exchanger unit 9, which is designed as a wall penetration. The support unit interior units 25a here function to transport the air through the building. In this way, a great deal of air transport is achieved, and thus a cooling effect is also possible, while the building is cleansed of unwanted substances.
    In FIG. 4, it is shown how an indoor unit 25 ventilates a room 3 with the air in the hallway 9, i.e. the air supplied by the switching units and the indoor units 25a with support function.
    According to a preferred embodiment of the invention, as a wall heat exchanger, a countercurrent heat exchanger embedded in a molded or adapted insulating material is used.
    The design of such a wall heat exchanger 9 for placement in a wall is shown in FIG. 5. Here is shown a joined heat exchanger part 10 which is to be enclosed by two parts 11 and 12 of molded insulating material. The two parts each constitute a half cylindrical shell which can be joined together to form a pipe-like structure. The reference numeral 13 indicates an example of a series of recesses in the insulating pipe 11, 12, which recesses 13 are used to hold the heat exchanger part itself. The heat exchanger portion consists of stacked exchanger plates 14, 17, and the exhaust air is conducted on one side by an exchanger plate and the intake air on the other side so that heat is exchanged through the plates. In the illustrated embodiment, this is accomplished by bending every other plate 14 to form upwardly extending tabs 15 extending over approx. half of the width of the plate 14, on one diagonal and downwardly extending tab 16, which also extends over approx. half the width of the plate 14, on the other diagonal. For practical reasons, it is shown that
    DK 2018 70630 A1 prefer that the bend is the same at both ends of the plate. The plates are stacked alternately with a bent plate 14 and a flat plate 17, so as to create in one layer diagonal flow through the exchanger 10, for example from left to right, while the flow in the layer above and below also extends diagonally, but from the right towards left (Fig. 6). This ensures a long way for the air through the heat exchanger with good heat exchange. In the preferred embodiment, the exchanger plates 14, 17 are bonded together and inserted as a total unit 10 into the insulating holding member. In the preferred embodiment shown, as holding and insulating part 10, 11 is a cellular plastic type, such as a relatively hard type of foamed polystyrene, which has both good insulation properties and sufficient strength. The exchanger part 10 and the holding and insulating part 10, 11 can be dimensioned so that the exchanger part 10 is held in place by the pressure of the insulating part 10, 11, but in the preferred embodiment the insulating part 10, 11, as shown in FIG. 5, provided with grooves 13, to which the exchanger part 10 fits, to ensure better retention.
    There is shown here an exchanger part 10 which is substantially circular in cross section. Hereby the maximum heat exchange effect is obtained in relation to the cross-sectional area, but if the consideration for an easy construction, where the slats have the same surface dimensions, weigh more heavily, the exchanger part can, for example, be designed with a substantially rectangular cross-section. Such a construction can advantageously be used for the exchanger 8.
    If it is desired to separate the exchanger and insulation / holding part, the holding part as shown in FIG. 5, advantageously carried out in two or more pieces 10 and 11 which are not glued together, but for example are held in place by the inner wall of the hole in which the unit is to be mounted. This makes it possible to pull the unit out of the wall and subsequently remove the insulation material and clean the slats.
    DK 2018 70630 A1
    The wall heat exchanger 9 works in the way that outdoor air has been preheated by the collector and in the first heat exchanger stage, but which will still usually be colder than the indoor air, is passed through the outer tube 10, 11, thereby passing the large number of thin aluminum slats 14, 17, whereby the temperature of the blown air approaches the temperature of the blown air. On the inside, the module is provided with a back plate 18 which is mounted on the wall, for example by screwing it in place. It is important that the suction air is discharged into the room in such a way that the fresh air is not immediately mixed with the dirty air, which can be done, for example, by passing the air more or less parallel to the module's back plate or by pushing the air in. in the building over a small area and with great force.
    The principle of the heat exchanger is also shown in FIG. 8. The heat exchanger is mounted with the two pipe halves 11, 12 in a wall 18. The reference numeral 19 indicates an inner shield and there may also be an outer shield 20. The outward air flow 21 moves diagonally through the exchanger unit and gives heat to the inward air flow 22 which also moves diagonally through the exchanger unit.
    Additional units (not shown) may be provided in connection with the exchanger 9 for cooling or heating the blown air.
    In FIG. 9, an example is shown of a way of mounting fans 23, 24. As shown, the fan 23 can be simply mounted in the insulating material by being displaced into place. In order to obtain heat exchange, it is important that suction and extraction take place simultaneously. If, on the other hand, you want less heat exchange, the suction and suction can be temporarily offset, or the suction can take place through another vent.
    An example of a so-called inner unit 25 is shown in FIG. 10 to 13. In FIG. 10 ses
    GB 2018 70630 A1 the indoor unit 25 with an outer cover 26 which can also act as a guide plate for controlling the direction of the air in and out of the unit. Similarly, an inner cover 27 is provided with the same function. In FIG. 11 is a section through a preferred embodiment of the interior unit 25. Here is also shown the cover 26, which covers the outside of the interior unit 25. The cover 26 functions partly as cover and can, as mentioned, be used to direct both the sucked-in and the discharged air. in the desired directions, and there is a corresponding shield 27 on the other side of the wall (inside). Between the screens there is an inward flow channel 28 in which is located a blower 29 for blowing in, and an outward flow channel 30 in which there is a blower 31 for extraction. Between the flow ducts there is a separator 32, which in a preferred embodiment is provided with a sound attenuating material, in order to reduce the noise from the fans and the air movement, as well as to reduce sound transmission between the spaces connecting the indoor unit. The shown design of the flow channels 28 and 30 further helps to reduce the noise and sound transmission. Around the fans and flow ducts there is a flexible tube which acts as the unit's outer wall against the wall in which the unit is placed. In addition, for stiffening and retaining the inner parts of the unit, a piece of material 33, in this case polystyrene, is cut which is cut to the correct length to fit the wall thickness. The structure is enclosed within the wall by a pipe 34. The pipe 34 is flexible so that it can be adapted to different wall thicknesses. Arrows 35 and 36 indicate the flow of air into and out of the dual fan. The use of interior units of this type enables complete ventilation of buildings without pipes, ducts or hoses, which significantly reduces the cost of the system and facilitates installation. Such a unit 25 can thus ventilate a room with air from one room or another room without doing so with air directly from the outside via an outer wall. When the unit's supply air and exhaust can be controlled separately, it can help move the air through several rooms to which the doors can be
    DK 2018 70630 A1 closed, and in both directions, depending on whether cooling or heating of the building is desired. It is possible, for example, by properly designing the structure and by controlling the strength of the supply air to ensure that the blown air is pushed 2-5 meters into the space to be ventilated so that it does not mix with the extracted air, as shown in FIG. FIG.
    12th
    If a function is desired where the unit 25 contributes to generating flow through a building, suction and exhaust on the outside of the room may conveniently take place approximately perpendicular to the overall flow direction through the wall and with suction in the direction of the main unit and suction in the direction towards the secondary unit.
    Support units 25a, as mentioned, for example, are positioned at one end at a time, are designed like the other interior units 25, but will usually only function by blowing in one or the other direction so that the air is moved through the building. This ensures a good air flow without the use of pipes, even when doors are closed.
    An example of the use of sound absorbing materials 39 in the flow channels is shown in FIG. 13. Together with the geometric design shown, the use of sound-absorbing materials ensures a quiet operation and also ensures sound attenuation between the spaces connected to the indoor unit.
    An interior unit 25 of the above-mentioned type is easy to install, as only one hole in the wall and one wiring is required to obtain both supply air and exhaust, and it is possible to control the air flows to ensure good ventilation in the room. and an air movement throughout the building.
    An example of designing an application for controlling the equipment for
    DK 2018 70630 A1 ventilation of buildings will be described below.
    When the application is opened, you get to the front where there is an overview of the temperature measured in degrees Celsius, the humidity measured in percent and the CO2 level measured in ppm. From the front you can click on COMFORT ZONE, PAUSE, NO HOME and HISTORY respectively.
    By clicking on COMFORT ZONE you will be taken to another screen which also shows the overview of temperature, humidity and CO2 level, and in addition a slider for selecting temperature. It is a scale with a range of 4 degrees that can be moved in either direction to set to the desired comfort zone. When the desired comfort zone is selected, click back to the main menu.
    When you click on PAUSE, you get to a screen where, in addition to the overview, there is also a slider where the pause interval can be adjusted from 0 to 2 hours. During a break, only air circulation takes place inside the building. (This is the program the system switches to if the hood is turned on).
    When NO HOME is clicked from the main menu, you will come to a page where you can set to sleep when there are no people in the building. It is possible to set a time interval for each weekday, and it is possible to switch on and off the sleep mode every single day. In addition, it is possible to switch off completely from rest, which may, for example, be desirable in private homes during vacations where you stay at home.
    When you click HISTORY from the front, you get to a screen where there is a graphical representation of the development in temperature as well as humidity and CO2 levels in relation to the recommendations. The temperature
    DK 2018 70630 A1 you choose as it is individual, but a maximum humidity of 45% is recommended and the recommended CO2 level is 550 ppm. It is desirable that it is clear to see when the measurement results are above the recommended. On the page, it is possible to change scaling, for example, from hour 5 to day to month, for example to see changes in levels over a day, a month and a year.
