    AN ELEMENT BASED VENTILATION UNIT WITH ENERGY RECOVERY FIELD OF THE INVENTION
    The present invention relates to an element based ventilation unit with energy recovery comprising an inlet part housing filter units for filtering fresh air and stale air (38), a core part housing a heat exchanger in which heat is exchanged between the stale air and the fresh air, and an outlet part housing two fans for sucking in fresh air and stale air respectively through the ventilation unit with energy recovery. The parts being assembled along mated edges to form the ventilation unit with energy recovery and the mated edges being provided so that the inlet part and the outlet part can swap positions relative to the core part without modifying the parts so as to change the configuration of the energy recovery unit. In addition, each of the inlet part, the outlet part and the core part being formed by combining at least two elements.
    BACKGROUND OF THE INVENTION
    Recent years' increase in energy prices and concern for global heating has resulted in a focus on using energy in an efficient manner. Conventionally, heating or cooling of houses - or other buildings - comprises a heat source which raises the temperature of the air in the building. The air inside the building must be renewed to maintain an acceptable air quality in the buildings. Conventionally, the renewal of air includes exhaust hot (or cold air) to the exterior and sucking in cold air (or hot air), and the temperature difference between interior and exterior air represents energy that can be transferred at least to some extent from e.g. the hot interior air to the colder exterior air using an energy recovery unit including fans, pipings, heat exchanger etc. Such heat exchanger will reduce the net energy used to heat the air in the building.
    Such energy recovery units are often relatively large and require a substantial foot print in the building in which they are to be installed. Further, the architecture of buildings often varies a lot and even in apartment buildings, the individual apartments differ at least to the extent of different requirements such as piping to and from the ventilation unit with energy recovery.
    While other needs may prompt a desire for the present invention, differences in layout and architecture result in ventilation units with energy recovery in many instances tailored to fit into a given building resulting in increased production costs and delivery time. Further, service of such energy recovery units is difficult due to the large variety of embodiments tailored to specific physical restrictions. US 4,322,229 discloses an example of a unitary matrix, valve and fan housing for energy recovery. The housing is manufactured with a modular design allowing final on-site assembly in a number of varying configurations. However, the unit according to US 4,322,229 still suffers from the drawback that the unitary matrix is a fixed stand-alone unit housing fans and heat storage matrix providing only limited geometric flexibility.
    Therefore, an improved ventilation unit with energy recovery would be advantageous, and in particular a more geometrically flexible ventilation unit with energy recovery would be advantageous.
    OBJECT OF THE INVENTION
    It is a further object of the present invention to provide an alternative to the prior art.
    In particular, it may be seen as an object of the present invention to provide a ventilation unit with energy recovery that solves the above mentioned problems of the prior art with respect to higher degrees of geometric flexibility. A further object may be to provide a ventilation unit being easy to assemble and having economic production costs.
    SUMMARY OF THE INVENTION
    Thus, the above described object and several other objects are intended to be obtained in a first aspect of the invention by providing an element based ventilation unit with energy recovery comprising an inlet part housing filter units for filtering fresh air and stale air, a core part housing a heat exchanger in which heat is exchanged between the stale air and the fresh air, and also containing a tray and pump for collecting and removing condensate from the heat exchanger, an outlet part housing two fans for sucking in fresh air and stale air respectively through the ventilation unit with energy recovery.
    The parts being assembled along mated edges to form the ventilation unit with energy recovery, the mated edges being provided so that the inlet part and the outlet part can swap positions relative to the core part without modifying the parts so as to change the configuration of the energy recovery unit, except from revealing or closing pre-formed openings in the elements to provide inlets or outlets, as needed. In addition, each of the inlet part, the outlet part and the core part being formed by combining at least two elements.
    Preferred embodiments of ventilation units according to the present invention are characterized in that the parts are at the same time load bearing and provided thermal insulation of the ventilation unit.
    Preferably, the parts of the ventilation unit are preferably provided so that once assembled into a unit, the unit is liquid sealed and no further sealing of the unit is needed.
    In the present context a number of terms are used to a lesser extent to a skilled person. However, some of these are explained in further detail below.
    Housing is preferably used which means that an item is contained within the housing part of the item.
    Mated edges are preferably used to mean edges that are adapted to each other so as to fit together.
    Swap is preferably used to mean the process of two elements or parts changing positions in the unit in a minor where a first element or part takes the position of a second and the second part or element takes the position of the first. During such swapping, the orientation of the parts or elements involved may be rotated.
    No modification of the parts is preferably used to mean that the elements of which a part is composed maintain their geometry (e.g. no mass modification process is applied to the elements), although their mutual orientation may be changed. A configuration of the unit is preferably used to mean a distinct assembly of the various parts and elements.

    DETAILED DESCRIPTION OF EMBODIMENTS
    Figure 1 shows an assembled view of a ventilation unit with energy recovery according to a first embodiment of the invention and in a first configuration.
    The ventilation unit with energy recovery A is intended for installation in e.g. houses and apartments, and includes an opening for inlet or stale, inside air as well as an opening for inlet or fresh outside air. A fan inside the ventilation unit with energy recovery enables air to flow into the ventilation unit with energy recovery A. The ventilation unit with energy recovery further comprises a flow path for the stale, inside air and another flow path for the fresh outside air, which flow paths include a heat exchanger through by means of which the heat goes from the warmer air flow to the cooler air flow.
    In situations where the indoor temperature is higher than the outside temperature, the stale, warm, inside air enables a heating of the fresh, cool outside air and exhaust the fresh warmed-up air to the inside environment and exhaust the stale, cooled air to the outside surroundings. In the same way, if the indoor temperature is lower than the outside temperature, the ventilation unit with energy recovery can be used to cool down the incoming fresh, warm, outside air and exhaust this to the indoor environment.
    Due to the element based structure (as will be further detailed below) of the invention, the ventilation unit with energy recovery may be configured in a number of ways, as will be disclosed in further detail in a later paragraph. This entails the advantage of a geometrically flexible construction, and that the openings for inlet and outlet of air can be positioned depending on the location and orientation needed, e.g. laterally or up / down reversed from the configuration on figure 1, which gives an advantage in e.g. apartment buildings, where a large number of ventilation unit with energy recoveries are required, and where apartments are laterally reversed, as the very same elements can be used for establishing ventilation unit with energy recoveries meeting different geometric requirements or desires.
    The ventilation unit with energy recovery A typically consists of 17 different elements and 22 elements in total. All possible configurations require use of the 22 elements. This will ease the work load in packing and storage since the same elements are stored and delivered not depending on the required configuration.
    With reference to figure 1, the ventilation unit with energy recovery A comprises three parts: an inlet part B, an outlet part C, and a core part D. These parts are indicated by indication lines 50 in the figures, which indication lines 50 are not part of the unit. Each of the parts is hollow structures being adapted to defined flow paths and housing functional parts (filters, fans, heat exchanger, drip tray etc.) of the ventilation unit with energy recovery A. The inlet part B and the core part D have mated edges defined by the extremities and upon assembly of the inlet part B and the core part D these mated edges abut each other, and typically form a fluid tight seal.
    Similarly, the core part D and the outlet part C have matted edges which upon assembly abut each other typically to form a fluid tight seal.
    The inlet part B comprises an opening for inlet of fresh, outside air 24 and an opening for exhausting inside air 25. The outlet part C comprises an opening 29 for exhausting stale, air to the outside surroundings. Exhaustion of heated (or cooled) outside air 39 into the building is done through an opening 30 in the core part D.
    Figure 2 shows an exploded view of the ventilation unit with energy recovery in accordance with a first embodiment of the invention and in a first configuration.
    The inlet part B, the outlet part C, and the core part D define a sealed unit where internal flow paths are defined by internal wall parts of the elements in combination with the exterior of the elements.
    The inlet part B comprises two filter housing elements 3 and 4, an inlet element 10, two plug elements 16, and a plug element with a hole 17. The hole is intended for a sensor arranged to measure e.g. the temperature inside the ventilation unit and wires to the sensor extend through hole 17, and a sealing is provided to seal the hole once the wire and sensor is arranged. Such hole 17 may be provided at other locations of the ventilation unit, or the position of elements 17 and 16 may swap.
    The filter housing elements 3 and 4 are assembled for housing a ventilation filter as well as inlet or outside air, i.e. circular shaped inlet openings 21, 22, 23, and 24, and furthermore square shaped inlet opening 25 for inside air. The two plug elements 16 are assembled to the openings 21 and 22 and thereby blocking the openings 21 and 22, and the plug element with a hole 17 is assembled to the opening 23 and thereby blocking the opening 23, thus leaving one opening 24 unblocked. for inlet of air. The square shaped inlet element 10 is assembled to the opening 25. The square shaped opening 25 has the dimensions in accordance with ventilation requirements. The square shaped element 10 is assembled towards the top edge of the square shaped opening 25 leaving an opening towards element 4 in the bottom of the square shaped opening 25 for inlet of inside air.
    The outlet part C comprises two motor elements 6 and 7, two fan elements 13, and three plug elements 16.
    The motor housing elements 6 and 7 are assembled for housing an engine as well as exhausting air, i.e. circular shaped outlet openings 26, 27, 28, and 29, and also enabling assembly of the square shaped ventilation elements 13, which are assembled between the two motor elements. The three plugs 16 are assembled to the openings 26, 27, and 28 blocking the openings 26, 27, and 28, thus leaving one opening 29 unblocked for exhaust of air.
    The core part D comprises a square shaped silencer element 11 which has a square shaped opening 30 on one side. The core part D further comprises an outlet element 12, a channel element 8, a pump insertion element 14, a filter motor element 9, two center elements 1 and 2, a pump element 15 and a channel element 5.
    The outlet element 12 is assembled to the opening 30 of the silencer element 11 enabling air outlet and silencing sound in the air. The channel element 8 is assembled to the silencer element 11 enabling an air channel. The channel element 8 is assembled to center element 2 providing two square openings 31 and 32. The square shaped pump insertion element 14 is assembled to the opening 31 of element 8 enabling continuous air flow through the channels, and the square shaped filter motor element 9 is assembled to the opening 32.
    Channel element 5 is assembled to center element 1 enabling continuous air flow through the channels, and also enabling a square shaped opening 33. The pump element 15 is assembled to the opening 33. The two center elements 1 and 2 are assembled providing a section center section between the channel elements 5 and 8, thus enabling assembly of part B and C to part D.
    All elements of the ventilation unit with energy recovery A are made of expanded polypropylene (EPP) and are produced using heat molding. The corners are rounded and angles between adjoining surface provided so as to provide mold slip.
    All elements of the ventilation unit with energy recovery A abut one or more elements, and the edges of an element that abut another element has a special design which serves as an assembly mechanism to seal the gap between two elements and thermally insulate, and preferably also electrically insulate, the ventilation unit with energy recovery A. The edges of an element which do not abut another element are rounded.
    The design of an assembly mechanism can be seen in figure 4, where one element (element Y on figure 4) has a male fitting, and the other element (element X on figure 4) has a female fitting. The female fitting is placed on the mated edge of one element and comprises a slot 46 along the edge, and the opposite male fitting is placed on the mated edge of the other element and comprises tongue 47.
    Due to the low stiffness of EPP, it is possible to assemble the male fitting into the female fitting by pressing the two elements against each other and thereby slightly bending the slot 46 of one element until the elements join and the slot 46 will rearrange to its default position. E.g. part D is assembled by the elements 1, 2, 5, 8, 9, 11, 12, 14, and 15.
    Element 1 and 1 are assembled and an edge of element 1 has a profile as element Y on figure 4, and the mated edge of the element has a profile as element X on figure 4. When pressing mated edges of elements 1 and 2 together the elements will attach.
    This assembly mechanism is used for fitting the elements together edge to edge and thereby strongly joining the abut elements and furthermore providing a smooth surface.
    Another way of assembling elements is shown on figure 5. All edges that abut another element have either a slot 48 or a ridge 49 placed on the middle of the edge. One element (element X 'on figure 5) has an edge with a spiky ridge 49, and the opposite element (element Y' on figure 5) has an edge with a matching slot 48.The ridge 49 projects a little less than the depth of the slot 48 allowing a thin layer of glue between the elements. The elements are assembled by applying the edge of one element to the mated edge of the opposite element joining the ridge 49 on element X 'to the slot 48 of the opposite element Y'. The ridges and slots serve as fix points for the assembly and before assembling two elements a thin layer of glue is applied to the edges giving means for keeping the elements together.
    Although not needed in many of the preferred embodiments, stabilization and support of the ventilation unit with energy recovery A, and prevent the elements and parts from detaching, a support structure may be applied to the ventilation unit with energy recovery (A). The support structure may preferably be in the form of a steel box or a box made from a fiber board, such as a medium density fiber board. Such boxes may also be applied to the ventilation unit to make it fire-retardent and / or to silence the ventilation unit.
    The box is designed with internal dimensions adapting it to receive the assembled parts and elements in a firm fit, and has openings corresponding to the openings 21-30 for all configurations of the ventilation unit with energy recovery A. The box is open on one side which serves as an opening for mounting the ventilation unit with energy recovery A, and after mounting the ventilation unit with energy recovery A into the box, the box is closed with a steel lid, which is fastened with one screw in each of the four corners of the member.
    The element based structure of the invention includes 32 different configurations of the ventilation unit with energy recovery A. For all configurations the same 22 elements are used. Figure 1 shows a configuration where the inlet of fresh outside air comes through the opening 24 while openings 21, 22, and 23 are closed with plugs. Since the plug 16 fits into any of the four holes 21, 22, 23, and 24, this gives four different openings that can be used for inlet of fresh outside air. The configuration shown on figure 1 shows that the stale air is exhausted to the outdoor environment through the opening 29 while the openings 26, 27, and 28 are closed with a plug, 16. Since plug element 16 also fits into any of the four holes 26, 27, 28, and 29, this gives four different openings that can be used for exhausting the stale air to the outdoor environment.
    With four possibilities for inlet of fresh outside air, and four possibilities for exhausting stale air to the outdoor environment, this gives 16 different configurations to be used. As can be seen in figure 10 it is possible to laterally reverse the ventilation unit with energy recovery A. When laterally reversing the ventilation unit with energy recovery A there are still four different possibilities for inlet or fresh outside air, and four possibilities for exhaust stale air to the outdoor environment, which gives another 16 different configurations to be used. In total this gives 32 different configurations to be used.
    Figure 6 shows an exploded view of the ventilation unit with energy recovery according to a second embodiment of the invention and in a second configuration. This configuration is a laterally reversed configuration of the first configuration on figure 2.
    The inlet part B comprises two filter housing elements 3 and 4, an inlet element 10, two plug elements 16, and a plug element with a hole 17.
    The filter housing elements 3 and 4 are assembled for housing a ventilation filter as well as inlet or outside air, i.e. circular shaped inlet openings 21, 22, 23, and 24, and furthermore square shaped inlet opening 25 for inside air. The two plug elements 16 are assembled to the openings 22 and 23 and thereby blocking the openings 22 and 23, and the plug element with a hole 17 is assembled to the opening 21 and thereby blocking the opening 21, thus leaving one opening 24 unblocked. for inlet of air. The square shaped inlet element 10 is assembled to the opening 25. In general, units according to the present invention are preferably dimensioned according to a desired design criterion, typically restrictions as to dimensions (such as footprint) and yielding capacity. Accordingly, openings in the unit are typically sized to meet such criteria. The square shaped element 10 is assembled towards the top edge of the square shaped opening 25 leaving an opening towards element 3 in the bottom of the square shaped opening 25 for inlet of inside air.
    The outlet part C comprises two motor housing elements 6 and 7, two fan elements 13, and three plug elements 16.
    The motor housing elements 6 and 7 are assembled for housing an engine as well as exhausting air, i.e. circular shaped outlet openings 26, 27, 28, and 29, and also enabling assembly of the square shaped ventilation elements 13, which are assembled between the two motor elements. The three plugs 16 are assembled to the openings 26, 27, and 28 blocking the openings 26, 27, and 28, thus leaving one opening 29 unblocked for exhaust of air.
    The core part D comprises a square shaped silencer element 11 which has a square shaped opening 30 on one side. The core part D further comprises an outlet element 12, a channel element 8, a pump insertion element 14, a filter motor element 9, two center elements 1 and 2, a pump element 15 and a channel element 5.
    The outlet element 12 is assembled to the opening 30 of the silencer element 11 enabling air outlet. The channel element 5 is assembled to the silencer element 11 enabling an air channel. The channel element 5 is assembled to center element 2 providing two square openings 31 and 32. The square shaped pump insertion element 14 is assembled to the opening 31 of element 5 enabling continuous air flow through the channels. Channel element 8 is assembled to center element 1 enabling continuous air flow through the channels, and also enabling a square shaped opening 33 and 34. The pump element 15 is assembled to the opening 33, and the square shaped filter motor element 9 is assembled to the opening 34. The two center elements 1 and 2 are assembled providing a center section between the channel elements 5 and 8, thus enabling assembly part B and C to part D.
    The configuration on figure 6 gives an ventilation unit with energy recovery A which is laterally reversed from the configuration of the first configuration on figure 2 and still using the same elements. This is possible due to the fact that all elements have the same assembly mechanism, and it is therefore possible to swap some of the elements and still maintain a fluid tight sealing between the elements. Additionally, part B and part C have identical shaped edges along the edges that are assembled with part D, and they can therefore be swapped and reversed. The plugs 16 and 17 all fit into any of the openings 21-24 and 26-29 which therefore makes it possible to freely configure which hole should be closed and which should be left open. It is generally preferred to arrange the wires and connection of the ventilation unit so that they extend or face downward when the ventilation unit is in use.
    In order to maintain the interior flow paths of the ventilation unit with energy recovery A, some elements in part D are also swapped; however, elements 1 and 2 typically maintain their mutual position. I.e. element 8 and 9 are positionally swapped with element 5. This is also possible inter alia due to the fact that the elements have the same assembly mechanism. In addition, motor element 9 can be assembled on both opening 32 on element 2 and opening 34 on element 1. In addition, the flow path internally in the ventilation unit can be changed to meet the configuration of the elements. Additional elements 5 and 8 need to be swapped in order to maintain the flow paths of the ventilation unit with energy recovery A. However, both elements 5 and 8 also need to be able to be assembled with element 11, which is possible due to the fact that the assembly mechanism on both elements is the same. As also apparent from the figures, elements 14 and 15 maintain their position relative to elements 1 and 2.
    The various configurations of the elements make it possible to change the flow paths internally in the ventilation unit A so that e.g. The flow path is adapted to flow intentionally through the various components, such as filters, pump, condensate tray, condensate pump, heat exchanger.
    Figure 3 shows internal details of the embodiment of Figure 1; Figure 3 outer surfaces of the ventilation unit with energy recovery has been removed to reveal various functional parts of the ventilation unit with energy recovery A visible. In addition, flow paths for fresh air, bypass of fresh air and inside air are indicated.
    As indicated above and in figure 3, the ventilation unit with energy recovery A comprises the following functional features: two fans 35 and 45, a heat exchanger 36 and two filter units 37 and 38. The ventilation unit with energy recovery A further comprises a unit for collecting condensate from the heat exchanger 36, which is preferably placed below the heat exchanger 36. Fresh air 39 is sucked in using the fan 45 into the ventilation unit with energy recovery A through the opening 24 (see figure 1) and flows towards and through a filter unit 37 filtering particles having sizes larger than a given size off. The given size is selected during the design of the ventilation unit with energy recovery to meet a designer defined criterion. A preferred purpose of the filtering units 37, 38 is to avoid blockage of the heat exchanger 36 by particles contained in the airstream passing the heat exchanger 36.
    After the fresh air 39 has passed through the filter unit 37, the flow towards and through the heat exchanger 36 in which heat is exchanged with the inside air sucked into the ventilation unit with energy recovery A. After passage of the heat exchanger 36, the fresh air flows towards and through the fan 45, where after it leaves the ventilation unit with energy recovery A through opening 30 (see figure 2).
    The flow of inside air 40 into, through and out of the ventilation unit with energy recovery A is similar to the flow of fresh air 39. Thus, inside air 40 is sucked in by using the fan 35 into the ventilation unit with energy recovery A through the opening 25 and flows towards and though the filter unit 38, having the same function as a filter of particles as the filter unit 37. After passage of the filter unit 38, the air flows towards and through the heat exchanger 36 in which heat is exchanged with the filtered fresh air 39. After passage of the heat exchanger 36, the inside air 40 flows towards and through the fan 35, where after it leaves the ventilation unit with energy recovery A through opening 29 (see fig. 1) .
    During use of the ventilation unit with energy recovery A, it is often desired to have bypassed an amount of fresh air from going into the heat exchanger 36. This could e.g. due to the fact that a high efficiency of the heat exchanger 36 as a heat exchange requires a certain amount of airflow and that the need for fresh air exceeds that certain amount of airflow in the heat exchanger 36. The bypass is accomplished by leading an amount of fresh air, bypass air 41, towards the fan 45 in a flow path bypassing the heat exchanger 36, eg as indicated in fig. 3. The amount of bypass air 41 is determined e.g. by a valve arranged, adjustable shutters or similar typically being arranged at the outlet of the filter unit 37 (not shown).
    To avoid mixing of the various air streams in the heat recovering unit A, separate flow channels are defined in the heat recovering unit A in such a manner that inside air 40 is not mixed with fresh air 39 and bypass air 41 and vice versa. The flow channels are e.g. defined by separating walls e.g. as shown in fig. 3 with numeral 42a which separates the internal volume of inlet part B into two chambers 43 and 44 constituting two separate flow channels and housing the filter elements 37 and 38.
    The fans 35 and 45 are preferably low noise centrifugal blower fans of conventional types. The rotational speed of the fans is preferably adjustable so as to render it possible to control the amount of air being sucked through the ventilation unit with energy recovery A.
    Figure 7 shows in a 3-dimensional view a further embodiment of a ventilation unit with heat recovery according to the present invention. The unit shown in fig. 7 contains a different shaped element 11 (with reference to e.g. Fig. 2) and this element 51 has a dimension extending along the full length of the unit. The element 51 has been provided with eight openings 52, which is shown in FIG. 7 as being circular openings although differently shaped openings. The openings 52 are configurable by suitable plugs (e.g. 16 and 17 in Fig. 2) to form inlet, outlet, exhaust, intake etc. as disclosed herein in 2 x 44 = 512 different combinations of arrangement.
    Although the present invention has been described in connection with the specified embodiments, it should not be construed as being in any way limited to the examples presented. The scope of the present invention is set out in the accompanying claim set. In the context of the claims, the terms "comprising" or "comprising" do not exclude other possible elements or steps.

The use of reference signs in the claims with respect to elements indicated in the figures shall also not be construed as limiting the scope of the invention. Furthermore, individual features mentioned in different claims may be advantageously combined, and the mention of these features in different claims does not exclude that a combination of features is not possible and advantageous.
