Definitions

  • the invention relates to a charging device for storage and boiler according to the preamble of the first claim.
  • This device is a housing with a built-in heat pump, which is mounted on a frame construction with the necessary connections and other installation.
  • the heat pump is designed for air / water, water / water or brine / water, whereby the heat pumps of the same size known today include the following versions:
  • the heat pump unit is directly connected to a hot water boiler and is arranged either on top of it or laterally to it and is known under the term HP boiler.
  • a heating spiral which plunges directly into the boiler and is coupled to the heat pump outside it, heats the hot water.
  • the heat pump is an independent unit which is connected to the heat pump boiler via two metal hoses, i.e. once below and once above, is connected, with a pressure-controlled throttle valve regulating the amount of water and thus the water temperature.
  • the object of the invention is therefore to provide a charging device or a heat pump system which does not have the disadvantages of the conventional designs described.
  • the heat pump to be created should e.g. can be used in systems of the type described in EP-B-0 227 051.
  • a cube-shaped housing is best suited to accommodate the supply and exhaust air supply, the compressor and the evaporator in a housing that is as small as possible, the size of which is fixed for different outputs, and always has the same side lengths .
  • the side length for heating capacities up to 5 kW is only 55 cm, which is a huge compared to the previous versions Reduction in mass means.
  • a chair-like frame structure 12 including the entire, ready-to-connect piping is shown.
  • the frame structure 12 can either be mounted freely in the room or on a wall.
  • screw connections 13, 14 at precisely defined intervals the heat pump connected or screwed after installing the housing 1.
  • a mixing valve 2 with drive 3 and a pipe 4 for the lower water layer in a boiler or storage 15 (FIG. 5), a pipe 5 for the upper water layer in the storage 15, and a pipe 6 for a hot water flow are shown.
  • the lines 4 and 5 are connected via shut-off valves 10 and thermometers 9 via the mixing valve 2 with the drive 3 and a plug connection 23 to the heat pump 1.
  • a safety or pressure relief valve 25 is arranged parallel to the plug connection 23.
  • the screw connection 13 is arranged between the plug connection 23 and the heat pump 1.
  • the pipeline 6 is connected to the screw connection 14 via a shut-off valve 10, a thermometer 9, a charging and circulation pump 8, and a further electric register 26.
  • a temperature controller 7 is located in front of the pipe connection or the screw connection 14.
  • connection type corresponds to that according to EP-B-0 227 051.
  • the housing of the heat pump 1 is connected at the top to the two screw connections or pipes 13 and 14 and at the bottom to a drip water line 11, the one pipe 13 being connected to a mixing valve 2 controlled by a drive 3.
  • This mixing valve 2 draws water from two different layers of a reservoir 15 and delivers the water mixture determined by the drive 3 to the heat pump (not shown) accommodated in the housing 1.
  • the heated water flows from the condenser of the heat pump 1 through the pipe 14 into the pipe network on the one hand and on the other hand a part thereof into the boiler or storage tank 15.
  • the housing 1 is built on the frame structure 12 and consists of an independent heat pump unit, which is provided on the rear with two connections for the two pipes 13 and 14 and for the drip water line 11. Furthermore, the housing 1 is connected to the drip water line 11 with a connection via a flexible plastic or rubber hose. There is also an electrical cable with a plug on the housing 1 for the connection to the control box 18.
  • the housing 1 of the heat pump has the same dimensions for all outputs within a certain range and a side length of 55 cm up to an output of 5 kW.
  • the housing 1 contains the parts belonging to a heat pump, such as evaporators with fans, compressors, expansion valves, condensers and thermostats.
  • an air screen 21 is attached through which the room air is sucked in by a fan. The air is blown back into the room through three air grilles 21 on the adjoining side walls 20, 20 'and at the top of the housing.
  • 5 to 8 show the use of the accumulator charging device in various hot water systems, only one boiler being used in FIGS. 5, 7 and 8, whereas two boilers are used in FIG. 6.
  • 5 and 6 each show a heat pump 1, while in FIGS. 7 and 8 three heat pumps 1 are used, which are connected in parallel.
  • a group of tapping points 27 is assigned to each of the individual heat pumps 1, while in FIG. 8 all the heat pumps 1 feed together a group of tapping points 27.
  • 5 to 8 each show a circulation pump 28, an on and off thermometer 29 and a fitting or connection 30.
  • a check valve 31 is provided.
  • the greatest advantages of the present embodiment include the small dimensions, the compact design, the low-noise operation, and the low weight of the housing 1 with content.
  • a malfunction or failure of the heat pump it can be carried out in a few minutes. can be replaced by simply loosening the two screw connections 13, 14 on the housing and the plug on the electrical control box 18 is pulled out.
  • This quick and easy exchange option makes it possible to have the device replaced by a worker or caretaker, without the need for a heating technician.
  • the duration of an interruption in the event of a heat pump failure can thus be reduced to a minimum, which is a very great advantage over previous designs.
  • the storage charging device described is intended, inter alia, for use together with that heat pump device which is disclosed in EP-B-0 227 051.
