Definitions

  • the invention relates to a heat pump with a base frame receiving the heat pump units with the interposition of vibration damping elements, in turn on feet provided with vibration damping elements, and with a self-supporting, hood-shaped housing which is independent of the base frame and which can be put over the base frame with the units mounted thereon, on its inside has a sound absorption coating.
  • a heat pump of this type is known from EP-A-97 86, which belongs to the prior art according to Art. 54 (3).
  • the base frame is designed here as a shelf-shaped frame with a plurality of compartments delimited by intermediate shelves arranged one above the other, in each of which a heat pump unit is accommodated.
  • the casing forming the casing is provided with a circumferential wall, so that it must be lifted off as a whole if maintenance or repair work is to be carried out.
  • the disadvantage here is that this housing must first be raised so far that its lower edge projects beyond the outer contour of the heat pump. Only then can it be moved sideways and parked in a suitable place. The handling of such a housing therefore proves to be very cumbersome and difficult.
  • a heat pump is known which is accommodated in an hermetically sealed, heat-insulated cell together with an associated heat accumulator and water heater as well as all fittings in order to avoid heat losses.
  • this cell should be formed by a slip-on box. Since such a box for exposing the heat pump must first be raised to such an extent that its lower edge projects beyond the outer contour of the heat pump, the same disadvantages arise that have already been stated above in connection with EP-A-97 86.
  • structure-borne noise may also be transmitted in the arrangement according to DE-U-77 15 448, since no vibration damping elements are used here and the slip-on box is to be connected to the box bottom receiving the heat pump without the interposition of a seal.
  • DE-U-79 08 625 shows a so-called module heat pump with several modules arranged one above the other. These consist of a carrier plate on which all module units are mounted. However, no vibration damping elements are provided between the carrier plate and the module units. The carrier plates are taken up like drawers on slide rails. Intermediate vibration damping elements are also not provided here.
  • the slide rails mentioned are in turn attached to a housing that surrounds all modules. This housing should be provided with sound insulation. It is to be feared, however, that structure-borne noise is transmitted as a result of the direct connection of sound-generating units via the carrier plates and the slide-in rails with the supporting housing parts. Quite apart from this, laborious disassembly of the sound insulation is required to achieve access to the individual units.
  • the base frame is formed in a pallet shape and is provided with a rear wall which is penetrated by supply lines and has a sound-absorbing mass which extends to the bottom, which is stiffened at least in the lateral and upper edge region and on which the housing, which is one of the rear wall has corresponding recess and is provided on its lower edge with a sealing strip, with its sound absorbing coating.
  • the use of a pallet-shaped base frame advantageously enables one Easily accessible arrangement of the various heat pump units, which are damped against each other and against the base frame.
  • the sound generated from the heat pump units which are so insulated from one another in terms of sound, is encapsulated by the slip-on housing and the rear wall engaging in it. Since the housing is recessed on the rear wall and the soundproofing rear wall closing this recess can be arranged in a stationary manner, it is advantageously possible here to simply pull the soundproofing housing forward without having to disassemble supply lines or raise the housing. This also ensures that the amount of space required is extremely low, which is extremely advantageous when installing heat pumps in poorly accessible rooms. Another advantage of the decoupling according to the invention.
  • Machine construction and soundproofing cladding can also be seen in the fact that the soundproofing cladding can also be easily removed for transport purposes, so that the entire heat pump can be transported in the form of smaller units.
  • the measures according to the invention therefore result in excellent maintenance and installation friendliness. Nevertheless, sound bridges leading to the outside are reduced to such an extent that resonances leading to mutual reinforcement are practically not to be feared even within a large working area within which a heat pump can operate, which further measures for acoustic control of the large heat pump working area can advantageously be dispensed with makes.
  • a particularly compact, yet clear arrangement of the units to be accommodated on the pallet-shaped base frame results if they are arranged in the form of the compressor, the evaporator and the condenser in a coaxial construction.
  • the circumferential sealing strip of the hood-shaped housing can expediently be provided with a movable sealing lip, which can advantageously also adapt to larger uneven floors or the like, which cannot significantly simplify the effort involved in setting up the installation site of the heat pump according to the invention.
  • the rear wall can have on its outside a circuit board with recesses for the supply lines, the edge of which is provided with an approximately U-shaped mount for the sound absorbing compound and is fastened to the base frame by side tabs.
  • the recesses assigned to the supply lines can expediently have an oversize with respect to the respective line diameter, so that direct body contact is avoided and the sound bridges leading to the outside are thus reduced to a minimum.
  • control unit assigned to the units is accommodated in a control cabinet which is separate from the base frame and housing and is arranged above it.
  • the control cabinet can advantageously be provided with holding legs which can be fixed on the rear wall. This ensures that the hood-shaped frame can be removed without dismantling the control cabinet and vice versa.
  • the use of a separate control cabinet also facilitates the introduction of the heat pump according to the invention into a room that is difficult to access.
  • the heat pump indicated schematically in FIG. 1 consists, in a manner known per se, of an evaporator 1, a condenser 2 and a compressor 3.
  • the structure and mode of operation of a heat pump are known per se and therefore do not require any further explanation at this point.
  • the machine units in the form of the evaporator 1, condenser 2 and compressor 3 are mounted on a pallet-shaped base frame forming the machine frame.
  • the base frame 4 is supported on four feet 5, which are provided with vibration damping elements 6 to reduce the noise, which can preferably be designed simply as a rubber or plastic buffer.
  • the machine unit outlined above is encapsulated for sound insulation by means of a separate housing, designated as a whole by 7, which is placed over the base frame 4 and the units 1 to 3 accommodated thereon in the manner of a hood.
  • the hood-shaped housing 7 consists of a self-supporting outer wall 8, which is produced, for example, as a plastic or sheet metal blank and is lined in the area of the inside of the housing with a sound-absorbing coating 9, for example in the form of a foam rubber sheet or the like.
  • the bottom edge of the housing 7 is provided with a circumferential sealing strip 10, which is made of so-called called sponge rubber or the like can exist and compensates for unevenness in the heat pump installation site, which ensures excellent encapsulation even on relatively uneven ground.
  • the hood-shaped housing 7 can be easily removed to expose the machine units indicated at 1 to 3, which clearly ensures ease of maintenance and also enables transport in several units. Nevertheless, the hood-shaped housing 7 ensures excellent encapsulation of the machine units, without this resulting in an excitation for natural vibrations, so that the respective operating point of the heat pump has no influence on the noise development.
  • the pallet-shaped base frame 4 consists of circumferential angle rails 12, on which two cross members 13 are fastened, which in turn receive the machine assemblies, which are interposed on this with the interposition of vibration damping elements described in more detail below.
  • the compressor 3 is provided with feet 14 formed by angled tabs or the like, which are underlaid with a vibration-damping element 15, here in the form of a simple rubber or plastic buffer.
  • the evaporator 1 and the condenser 2 consist of stacked coils surrounding the compressor 3, which are held by support struts 16 welded to the cross members 13.
  • the support struts 16 are provided at their free end with a pipe clamp 17 which, as can best be seen from FIG.
  • a vibration damping element also designated 15, here in the form of a rubber or plastic ring or the like is.
  • the vibration damping elements 15 used in the area of supporting the machine units ensure that the machine vibrations, which are generally unavoidable, are largely kept away from the machine frame itself.
  • the evaporator 1 and the condenser 2 are arranged one above the other and placed around the compressor 3. This coaxial design results in a particularly compact machine unit, over which a hood-shaped housing can be put very easily.
  • the base frame 4 is provided with a rear wall 19 penetrated by the supply lines 18, against which the correspondingly recessed hood-shaped housing 7 rests with its shell swallowing coating 9.
  • the rear wall 19 is overlapped by the corresponding edge of the housing 7.
  • the sound-absorbing coating 9 can be provided with a corresponding edge fold 20. The fact that the housing 7 rests only with its sound-absorbing coating 9 on the rear wall 19 means that the transmission of structure-borne noise is practically impossible.
  • the rear wall 19 is in turn provided with soundproofing mat 21, which is stiffened on the housing side and stands with its lower edge 22 on the heat pump installation site and thus seals in the manner of a sealing strip, in order to achieve sound insulation.
  • the sealing strip 10 of the housing 7 provided for the sealing on the bottom side of the housing 7 can, as can be seen from FIG. 2, have a movable sealing lip which is able to compensate for wide tolerances in the flatness and fineness of the heat pump installation site.
  • a board 23 made of sheet metal or plastic can be advantageously provided, which is bent at the edge in a U-shape. This results in an edge-side socket 24 for the sound-absorbing mat 21 and a clean, defined system for the hood-shaped housing 7.
  • the rear wall 19 is simply connected to the base frame 4 by side tabs 25 fixed in the region of the U-shaped angled portion. In the embodiment shown in Figure 2, the tabs 25 are welded to the side angle rails 12 and fixed by screws on the rear wall 19.
  • the board 23 is excluded for the implementation of the supply lines 18.
  • the corresponding recesses 26 of the board 23 are expediently oversized compared to the line diameter, so that the transmission of structure-borne noise is excluded.
  • the supply lines 18 are formed in the water-water heat pump shown by hose or pipe socket, the diameter of which is small compared to the clear cross section of an air duct of an air-water heat pump, so that the size of the recesses 26 advantageously remains within limits.
  • the control cabinet 1 .1 which is independent of the machine structure and the soundproofing cladding, can be fastened to a building wall or the like.
  • the control cabinet 11 is releasably attached to the rear wall 19.
  • the control cabinet 11 is provided with two holding legs 27 which are simply provided in the embodiment shown in the rear wall bushings 28 formed by profile tubes can be inserted. This results in a simple plug connection, which has an advantageous effect on the assembly or disassembly of the control cabinet 11.
  • the insertion length of the holding legs 27 is expediently chosen so that the hood-shaped housing 7 can be manipulated freely under the control cabinet 11 located above it. For maintenance of the machine units located under the hood-shaped housing 7, it is therefore not necessary to remove the control cabinet 11, which also has a positive effect on the ease of maintenance.
