Definitions

  • the invention relates to a heat pump, in particular an air-water heat pump, according to the preamble of claim 1.
  • a heat pump is, for example, from the DE 30 27356 A1 known.
  • This heat pump consists of a housing through which ambient air flows, a flow guide for the ambient air arranged in the housing and a sound-emitting heat pump component assigned to the flow guide and interacting with the ambient air.
  • This heat pump is used, as the term air-water heat pump expresses, to transfer the heat present in the ambient air to a liquid heat transfer medium, in particular heating circuit water of a building. Used the other way round, the heat pump can also be used to cool the building.
  • ambient air is to be understood here and also in the case of the inventive solution to be explained, the air that surrounds the heat pump, that is, for example, temperature-wise, weather-dependent fresh air outside a building.
  • the term “heat pump component” is to be understood in particular as a fan assigned to a heat exchanger. This emits on the one hand due to its electric motor drive, on the other hand but also when the ambient air meets the fan blades, sound.
  • the compressor or the compressor, the evaporator or even valves of the heat pump come into consideration as the heat pump component, ie the term “heat pump component” ultimately refers to all possible, ultimately but at least one sound-emitting component of a heat pump.
  • the ambient air flows into the heat pump via an inlet opening on the right-hand side of the housing. It then flows upwards via a flow guide, there to a sound-emitting component (a fan assigned to a heat exchanger) and from there again downwards via a or the flow guide to an outlet opening on the housing.
  • a sound-emitting component a fan assigned to a heat exchanger
  • the invention is based on the object of improving a heat pump of the type mentioned at the beginning. In particular, an even quieter heat pump is to be created.
  • the housing in this solution is apparently cuboid, ie the flow guide for the ambient air is or the inlet and outlet openings for the ambient air are only provided on two sides of the housing, in Figure 1 left and right. There is no flow guide on the front and rear sides parallel to the plane of the drawing, ie emitted sound is more easily transmitted to the outer walls of the housing on these sides than in the area of the flow guide.
  • the flow guide envelops the heat pump component like a jacket, ie at least from all vertical sides of the housing.
  • the flow guide it is provided with regard to the flow guide that it is designed such that it guides the ambient air in the form of a sheath flow around the heat pump component.
  • Such a core flow is not necessarily present in the heat pump according to the invention, but it is essential that the jacket flow in the solution according to the invention envelops the core flow or a corresponding component.
  • the sheath current can be more or less precisely rotationally symmetrical with respect to a vertical axis of the housing: if, for example, which is preferred, the housing is cylindrical, then in principle a very pronounced rotational symmetry results.
  • the housing is designed to be triangular or polygonal in cross section, for example Approximately three or more flow segments that are approximately symmetrical to one another (in the examples mentioned C 3 - or C n -symmetrical), although ultimately possible internals or circumferential singularities may be present in the flow guide, the basic rotation or But do not influence the rotational symmetry of the flow or the flow segments.
  • the flow guidance it is also preferably provided that it extends either from an inlet opening on the housing to the heat pump component or from the heat pump component to an outlet opening on the housing or even from the inlet opening to the outlet opening mentioned. If, for example, the inlet opening is only provided at one point on the circumference of the housing, the flow guidance ultimately begins at the point where the flow of the ambient air is actually designed as a sheath flow or at least roughly rotationally symmetrical for the first time. The same applies to the end of the flow guidance.
  • the invention further provides that the heat pump component comprises a fan with a vertically oriented axis of rotation and the fan is optionally assigned a cone-shaped or pyramidal flow deflection on the outflow side.
  • the heat pump according to the invention which is intended and designed for installation in the open air (that is to say outside of a building), is first explained in more detail with reference to its features. Finally, a functional description follows.
  • an inlet and / or outlet opening 2.1, 2.2 connected to the flow guide 2 is optionally provided on the housing 1 for supplying and removing the ambient air.
  • the inlet and / or outlet openings 2.1, 2.2 are optionally designed to be closed with an air-permeable screen element 12.
  • the flow guide 2 for forming a sheath flow of the ambient air in the housing 1 is designed to enclose the heat pump component 3 on its vertical sides like a sheath.
  • the heat pump component 3 of which comprises a heat exchanger 4 in a known manner it is provided that this heat exchanger 4 is enclosed by the jacket flow of the ambient air and is preferably designed as a lamellar heat exchanger through which the ambient air flows on the one hand and a refrigerant on the other.
  • the heat pump component 3 comprises, in a manner known per se, a preferably electric motor-operated fan 5, which, in contrast to the solution according to FIG.
  • the housing 1 viewed in horizontal cross-section, is optionally triangular, square, pentagonal or more than pentagonal or rounded, particularly preferred - see the embodiment according to FIG Figure 2 to 7 - is circular, is formed.
  • the flow guide 2 optionally from the inlet opening 2.1 on the housing 1 to the heat pump component 3, from the heat pump component 3 to the outlet opening 2.2 on the housing 1 or (at least in sections) from the inlet opening 2.1 to the outlet opening 2.2 extends is formed.
  • the inlet and / or outlet opening 2.1, 2.2 is / are arranged distributed over or the circumference of the housing 1.
  • Housing 1 which is circular in cross section, the openings are thus in principle in the surface of a cylinder ring.
  • there are corresponding edges in the surfaces for the openings wherein in principle webs or the like can also be provided between the openings.
  • the housing 1 has an upper and a lower housing section 1.1, 1.2.
  • An upper casing duct 2.3 (with a vertically oriented main axis) for supplying the ambient air is provided in the upper housing section 1.1 and a lower casing duct 2.4 (also with a vertically oriented main axis) for discharging the ambient air in the lower housing section 1.2.
  • the inlet opening 2.1 is arranged on the upper housing section 1.1 and the outlet opening 2.2 around the lower housing section 1.2.
  • the heat exchanger 4 is arranged in the upper housing section 1.1, which is particularly preferably designed as a ring cylinder with a vertically oriented main axis or, as seen in the horizontal cross section, ring-shaped.
  • the heat exchanger 4 is furthermore designed to delimit a first interior space 9 and is preferably designed for, in particular, horizontal guidance of the ambient air from the sheath flow into this first interior space 9.
  • the fan 5 already mentioned is assigned to the first interior space 9 of the heat exchanger 4, specifically particularly preferably, as shown, at the end of the ring cylinder on the housing-bottom side.
  • the fan 5 is optionally assigned a conical or pyramid-shaped flow deflector 6 which preferably opens out at the lower jacket duct 2.4 and is preferably formed from a sound-absorbing material, in particular polystyrene, on the outflow side. Its tip is particularly preferably designed to be aligned with an axis of rotation of the fan 5.
  • said lower jacket duct 2.4 is designed to delimit a second interior 10, with at least the compressor of the heat pump, preferably also a further heat exchanger, in particular a plate heat exchanger, a throttle element and parts of a cooling circuit of the heat pump being arranged in this or in the lower housing section 1.2 (not shown separately).
  • a support frame 7 for the heat pump components such as compressors, heat exchangers, etc. is arranged in the housing 1, to which in particular housing outer shells 8 are attached and which is preferably seen in horizontal cross-section (see in particular Figures 4 to 7 ) is rectangular, in particular square, is formed.
  • a first flow deflector 2.5 is provided in the housing 1 in the area of the inlet opening 2.1 and a second flow deflector 2.6 in the area of the outlet opening 2.2.
  • the flow deflector 2.5, 2.6 is optionally designed (that is, depending on the flow direction, which will be explained in more detail below) to deflect the ambient air from horizontal to vertical or vice versa.
  • a sound-absorbing material in particular polystyrene, is particularly preferably used as the material for the flow deflector 2.5, 2.6.
  • a sound insulation 11 is arranged between the jacket channel 2.3, 2.4 and an outer wall of the housing 1, in particular the aforementioned housing outer shell 8.
  • the heat pump according to the invention works as follows: Ambient air flows through the inlet opening 2.1, which is distributed over the entire circumference of the upper housing section 1.1 of the housing 1, into the upper jacket duct 2.3, whereby it is deflected from horizontal to vertical (upward) right at the beginning by the likewise full-circumferential flow deflector 2.5. Further attracted by the negative pressure generated by the fan 5, the ambient air located in the jacket duct 2.3 and surrounding both the heat exchanger 4 and the fan 5 flows next after a further deflection horizontally through the heat exchanger 4 into the (first) interior 9. There, the Ambient air deflected once more, this time downwards towards fan 5.
  • the intended transfer of heat takes place, either from the ambient air to a refrigerant flowing through the heat exchanger 4 (so-called heating mode) or from this to the air flowing through (so-called cooling mode).
  • the heat exchanger 4 is connected on the refrigerant side to the other typical components of a heat pump, for example with a compressor, a throttle element and another heat exchanger for transferring heat, for example via a refrigeration circuit (not shown separately) to a heating circuit in a building.
  • the components mentioned are preferably arranged in the second interior 10 and, as already explained, are also enclosed by a jacket duct 2.4 for the ambient air to be discharged.
  • the air passes after the fan 5 to the aforementioned conical or pyramidal flow deflector 6 and after this into the jacket duct 2.4 in the lower housing section 1.2. There the air flows vertically from top to bottom until it reaches a further flow deflector 2.6 and from there to the outlet opening 2.2, which is also distributed over the circumference.
  • the air sucked in via inlet opening 2.1 and blown off via outlet opening 2.2 is deflected several times within the heat pump.
  • all the sound-emitting components are completely enclosed either by the upper or lower casing duct 2.3, 2.4, ie sound generated inside the housing 1 can practically only leave the housing 1 indirectly.
