Definitions

  • the present invention relates to an air conditioner with a heat exchanger unit.
  • the heat exchanger unit is of a kind that may be installed at, e.g. hidden behind, a ceiling of a building or any other location providing for a limited installation space, particularly a limited height.
  • Heat exchanger units of this type are often also called duct-type heat exchanger units, which are connected to and form part of an air duct of an air conditioner.
  • heat exchanger unit An example of such heat exchanger unit is known from EP 2 108 897 A1 disclosing a heat exchanger unit having an L-shaped heat exchanger laying on its side, wherein air is flown through both legs of the "L".
  • a heat exchanger provides for a relatively small heat exchange surface in combination with a relatively uneven distribution of air flowing through the heat exchanger (uneven air distribution).
  • the height of the heat exchanger unit is relatively large, because the legs of the "L" shaped heat exchanger are arranged with their width oriented vertically.
  • a heat exchanger unit providing for a larger heat exchange surface and a lower height is disclosed in EP 2 402 669 A2 .
  • This heat exchanger unit implements a V-shaped heat exchanger with a central axis of the "V" oriented horizontally. Thereby, the height of the heat exchanger can be reduced at the same time increasing the heat exchange surface. Yet, the air distribution of air flowing through the heat exchanger is still relatively uneven, because the air is blown by a fan towards the apex of the "V" leading to reduced heat exchange efficiency.
  • a heat exchanger having the features defined in the preamble of claim 1 is known from WO 2015/033467 A1 as well as from JP H02 13923 U .
  • the heat exchange unit comprises a casing having a duct to be flown through by a fluid, particularly air (in the following reference is made primarily to air only, but it is to be understood that other fluids may as well be used).
  • the casing is particularly configured to be connected to a fluid path, particularly an air duct, e.g. connecting to a space to be conditioned or a heat source, particularly outside air. As such, the casing will be part of the fluid path.
  • a fan is disposed in the casing.
  • more than one fan may be provided.
  • the fan or fans are configured to induce a flow of the fluid through the duct in a flow direction.
  • a heat exchanger is provided within the duct and to be flown through by the fluid flowing through the duct by means of the fan/-s.
  • the heat exchanger is disposed in the duct so that no air may bypass the heat exchanger.
  • the heat exchanger is disposed in the air duct so that the entire amount or at least a major part of air flowing through the duct also passes through the heat exchanger.
  • the heat exchanger is V-shaped in a side or cross-sectional view with an apex at one end and an opening at the opposite end. The angle of the "V" may be adjusted as needed. The larger the angle, the better for achieving even air distribution and good efficiency. The smaller the angle, the better for obtaining a low height.
  • the heat exchanger may comprise two planar or plate shaped heat exchange elements which are positioned so as to form the "V". These elements may be fluidly connected by refrigerant piping to be flown through by refrigerant preferably in parallel. Further, these elements may be defined as an upper heat exchange element and a lower heat exchange element.
  • the terms "upper” and “lower” in this context refer to a centerline passing the apex and extending horizontally in use. This centerline may be a line of symmetry of the heat exchanger when seen in the side view and the heat exchanger may be disposed in the duct with the apex of the "V" being directed towards the flow direction.
  • the fan or fans is/are disposed downstream of the heat exchanger in the flow direction.
  • the fan is disposed further away from the apex than the opening of the heat exchanger or is disposed on a side of the opening of the "V" of the heat exchanger.
  • the fan is disposed downstream of the heat exchanger in the flow direction, it can be ensured that fluid is passing the whole or at least a major part of the heat exchanger at a relatively even amount distributed over the heat exchange surface of the heat exchanger (air distribution).
  • the fan establishes a lower pressure on the side downstream of the heat exchanger. Therefore, air is sucked into the duct from an upstream side of the heat exchanger flowing into an inlet opening of the duct and hence through the heat exchanger more evenly.
  • the amount of air is not as concentrated on a particular portion of the heat exchanger as in the prior art. Hence, a more even air distribution and thus higher efficiency may be achieved.
  • the heat exchanger is symmetric in the side view.
  • a line of symmetry of the heat exchanger in the side view extends horizontally.
  • the upper and lower heat exchange elements are preferably identical or at least substantially identical. All these measures assist in obtaining an even air distribution.
  • the center axis of the fan or fans, particularly their suction opening/-s is located on a line parallel with the centerline of the V-shaped heat exchanger particularly its line of symmetry.
  • the center axis of the fan or fans, particularly their suction opening/-s is located on a common line with the centerline of the V-shaped heat exchanger particularly its line of symmetry in the side view.
  • the fan or fans is/are a backward curved centrifugal fan.
  • the heat exchanger unit is disposed in a fluid path (air duct).
  • the heat exchanger unit is further preferably used as part of a heat source unit (also known as outdoor unit even if disposed indoors) and may be combined with a compressor or a separate compressor unit to constitute the "outdoor unit".
  • a relatively large pressure drop has to be overcome because of fences and filters. Therefore a relatively high ESP (external static pressure) is required.
  • a relatively high airflow is required so as to enable the use in an air conditioner supplying a plurality of indoor units disposed in the spaces to be conditioned.
  • normal outdoor units provide for an air flow of 120 m 3 per minute
  • common indoor units provide for an air flow of 30 m 3 per minute.
  • the appliance of the heat exchanger unit as described above only requires a lower flow rate as compared to normal outdoor units but a higher flow rate as compared to usual indoor units.
  • the use of a backward curved centrifugal fan is desirable to achieve a relatively high ESP and air flow rate with high-efficiency.
  • An additional requirement for the heat exchanger unit to be placed in the ceiling is that the whole unit and also the fans have to be restricted in regard of weight and size.
  • the fluid flow rate needs to be adjustable. Also these requirements can be met by the use of a backward curved centrifugal fan.
  • the flow rate to be induced by the fans resides between about 60 m 3 per minute and 100 m 3 per minute and preferably about 60 m 3 per minute and 85 m 3 per minute. This may efficiently be obtained with one or more backward curved centrifugal fans.
  • the flow rate should also be adjustable in the aforesaid ranges.
  • the use of a plurality of backward curved centrifugal fans further provides for a reduced overall fluid speed in the high velocity zones of the fans. Accordingly, the fans may be positioned closer to the heat exchanger without condensation water formed on the outer surface of the heat exchanger being drawn into the fans. By positioning the fans closer to the heat exchanger, a more compact heat exchanger unit as regards its length may be achieved.
  • the heat exchanger i.e. the opening of the heat exchanger must stay away from the fan between 20 and 30 cm to avoid water from being sucked into the fan at a flow rate of 85 m 3 per minute when two backward curved centrifugal fans are used.
  • the use of a plurality of fans leads to less noise because each fan may be driven at a lower RPM to reach a certain air flow rate as compared to the use of fewer fans to reach the same air flow rate.
  • the heat exchanger comprises a baffle plate disposed at the apex of the heat exchanger and directed towards the flow direction, i.e. facing the fluid flow (airflow).
  • the baffle plate provides for the advantage that a certain amount of fluid is deflected at the baffle plate so as to ensure that not all of the fluid passes the heat exchanger through the apex but is evenly distributed over the heat exchanging surface along the legs of the "V". Thereby an improved distribution of air flowing through the heat exchanger can be achieved. If the baffle plate covers the entire surface of the heat exchanger at the apex, that is the front faces of the heat exchanger elements at the apex, no air flows through the apex.
  • baffle plate only covers a part of the surface of the heat exchanger at the apex or front to surfaces of the heat exchanger element, some passes through the apex and a more even air flow through the heat exchanger at the apex may be obtained.
  • the baffle plate may be air impermeable, but it is also conceivable that the baffle plate is perforated to allow a certain amount of air to pass the baffle plate. Further, the baffle plate may be made of sheet-metal or EPS.
  • the baffle plate is symmetrical relative to the centerline or the line of symmetry, of the heat exchanger.
  • the baffle plate has, in the cross section or side view an equiangular triangular shape, wherein the apex of the triangle is located on the centerline of the heat exchanger and directed towards the flow direction.
  • the legs of the equiangular triangular shape directed towards the flow direction are convex.
  • the baffle plate has in cross section or side view a rounded shape, particularly a partial circular shape, wherein the center of the circle is located on the centerline of the heat exchanger.
  • the rounded shape provides for a larger amount of deflection as compared to the previously described shape.
  • the heat exchanger unit In order to collect condensation water formed on of the outer surfaces of the heat exchanger, the heat exchanger unit according to an aspect further comprises a drain pan.
  • the drain pan may be a drain pan which needs to be manually removed and emptied or drain pan that is connected to drainage.
  • the drain pan has a lowest position. If the drain pan is connected to drainage, a drain opening is disposed at the lowest position. According to an aspect it is preferred that the lowest position and if present the drain opening is disposed in that half of the drain pan away from the fan seen in the flow direction. In particular, the drain pan extends in a direction away from the fan. If the drain pan in this extension direction is separated into halves, the lowest position is positioned in that half that is further away from the fan than the other half. Furthermore, the drain pan is particularly designed so as to guide water accumulated in the drain pan away from the fan to its lowest position and if present the drain opening.
  • the heat exchanger unit further comprises an insulation (thermal and/or sound) disposed on an opposite side of the heat exchanger relative to the drain pan.
  • an insulation thermal and/or sound
  • the surfaces of the insulation and the drain pan directed toward the heat exchanger have approximated, preferably identical shapes.
  • the heat exchanger or heat exchanger elements each comprise loops of tubing with fins being interposed between the tubing. These fins are preferably waffled fins without any openings formed in the fins itself.
  • FIGS. 1 and 2 show a heat exchanger unit 1 in accordance with one embodiment of the invention.
  • the heat exchanger unit 1 comprises a casing 2 being configured for connection to an air duct of an air conditioner.
  • the heat exchanger unit is configured as an "outdoor" unit of an air conditioner which is however disposed inside particularly within ceiling of a building.
  • a first connection 3 is provided at the casing 2 for connection to an air duct communicating the heat exchanger unit 1 with the outside of the building and so as to enable sucking of outdoor air into the casing 2.
  • a connection 4 provided for the connection of the heat exchanger unit 1 to the air duct again leading to the outside of the building and to enable blowing out of air having passed the heat exchanger 5 to the outside is disposed at the opposite end of the casing 2.
  • the casing is substantially rectangular and flat, meaning that the height H is a smaller than the width W and the length L.
  • the height H is not more than 500 mm, preferably not more than 450 mm, more preferably not more than 400 mm and most preferred not more than 350 mm.
  • the heat exchanger unit 1 further comprises a heat exchanger 5 which is also visible in figure 1 .
  • a heat exchanger 5 which is also visible in figure 1 .
  • Figure 3 also represent a side view of the heat exchanger 5.
  • the heat exchanger 5 comprises an upper heat exchanger element 6 and a lower heat exchanger element 7. Both, the upper and lower heat exchanger elements 6, 7 are flat or planar shaped and are positioned with an angle ⁇ enclosed between them. Hence the heat exchanger 5 has a V-shape wherein the "V" is oriented horizontally. A centerline CL passing the apex 8 of the "V" is oriented horizontally, that is along the length L extension of the heat exchanger unit 1. The centerline CL is also a line of symmetry of the heat exchanger 5 as regards the heat exchanger elements 6, 7.
  • Heat exchanger 5 is arranged within the air duct formed by the casing 2 so that all air sucked in through the opening at the connection 3 has to flow through the heat exchanger 5 without any air bypassing the heat exchanger 5 at the top or the bottom or the sides of the heat exchanger 5 in the width direction W. Further, the apex 8 is directed towards the connection 3 and, hence, the flow of air introduced into the duct formed by the casing 2 and flowing there through.
  • the upper and lower heat exchanger elements 6, 7 are connected to each other at the apex 8.
  • the baffle plate 9 may be used for connecting the heat exchanger elements 6, 7 at the apex.
  • the baffle plate 9 is impermeable to air and as mentioned before can also be used to mechanically or physically connect the upper and lower heat exchanger elements 6, 7.
  • the baffle plate 9 serves for guiding the flow of air introduced through the connection 3 into the duct of the casing 2 along the upper and lower heat exchanger elements 6, 7 so as to obtain an as even as possible air distribution through the heat exchanger elements 6, 7. This effect is particularly described with respect to figure 4 .
  • Each of the heat exchanger elements 6, 7 comprises heat exchanger coils 10 (loops of tubing) and fins 11 disposed there between.
  • the heat exchanger of the present embodiment is particularly applied for outdoor applications, i.e. as part of the heat source unit of an air conditioner.
  • the fins of the upper and lower heat exchanger element 6, 7 are preferably waffled fins.
  • louvered fins may be used. Louvered fins are preferably for a good air flow through the heat exchanger as several holes are provided to allow the air to flow through the fins.
  • condensation water may accumulate in these holes and may lead to problems regarding the formation of frost during heating operation if used as outdoor application (i.e. when outdoor passes the heat exchanger), when the ambient temperature is lower than about 7°C. To prevent these problems it is in these cases preferred to use waffled fins.
  • Two backward curved centrifugal fans 20 are provided inside the casing. These backward curved centrifugal fans 20 each have a suction opening 21. In the side view ( figure 3 ), the center axis of the suction opening 21 and hence the fans 20 is substantially congruent or aligned with the centerline CL of the heat exchanger 5. In some appliances, it may however be sufficient as in the depicted embodiment that the center axis of the suction opening 21 and the centerline CL of the heat exchanger 5 are parallel but displaced relative to each other in a horizontal direction.
  • the fans 20 create a suction force at the suction opening 21 so as to induce a fluid flow (airflow) in the direction F.
  • air particularly outside air is drawn in through the connection 3 toward the apex 8 of the heat exchanger 5, passes through the upper and lower heat exchanger elements 6, 7 and is sucked through the suction opening 21 to be flown out through the connection 4.
  • the casing 2 defines a duct from the connection 3 via the heat exchanger 5 and the fan 20 to the connection 4.
  • the connection 3 and the connection 4 define an inlet opening 13 and an outlet opening 14.
  • a drain pan 15 is provided within the casing.
  • the drain pan 15 is separated into two halves 16, 17 along the length L of the casing 2 in the side view.
  • the two halves 16, 17 are identified by the dotted line with one half being located on the left side and one half being located on the right side of the dotted line.
  • the drain pan 15 has a lowest position 18 at which a drain opening 19 is provided.
  • the bottom of the drain pan 15 slants toward the drain opening 19 and hence the lowest position 18.
  • water dropping from any component into the drain pan is directly guided to the drain opening 19 and the lowest position 18 which is furthest away from the fan 20. Thereby it is prevented that water accumulated within the drain pan may be sucked into the fan 20 and hence through the opening 14 into the duct.
  • the drain opening 19 is directly connected to drainage so that water is directly drained.
  • a sound and/or thermal insulation 22 are provided within the casing 2 at the side opposite to the drain pan 15 with respect to the centerline CL.

  • the simulation in figure 4a visualizes that the selected shape of the baffle plate 9 avoids turbulences in an area 37 upstream of the baffle plate 9 as compared to a baffle plate 9 as shown in figure 4c ).
  • baffle plate 9 Similar may also be achieved when using a baffle plate 9 as shown in figure 4b ).
  • the baffle plate 9 in figure 4b has a rounded shape and particularly that of a partial circle. The center of the circle is again located on the centerline CL of the heat exchanger 5. Further apparent from the drawing, the baffle plate 9 covers the entire area of the apex 8 of the heat exchanger so that substantially no air is introduced into the heat exchanger 5 at the front facing the air flow F.
