Definitions

  • the invention relates to a device for generating hot water for heating and service water purposes in buildings with a heat pump, is removed by the heat of the environment, the heat pump of the environment in particular the exhaust air, the ambient air, geothermal and / or groundwater heat over a removes the first heat exchanger and increases in temperature via a second heat exchanger feeds a pump having a heating circuit, is fed through the heat to the heating surfaces and the service water.
  • the object of the invention is to provide a device of the type mentioned above with small outer dimensions, lower weight, lower cost and easy installation.
  • the invention integrates additional functions in the pump housing and avoids the copper tube by a direct connection of the pump housing with the plate heat exchanger.
  • the heat exchanger of a heat pump is the "primary heat exchanger" because it gets the calories from the condensing refrigerant of the heat pump.
  • the corresponding medium flow must flow from top to bottom.
  • the central heating water must therefore flow countercurrently from bottom to top in the plate heat exchanger.
  • the plate heat exchanger is mounted on the heat pump and the circulation pump is mounted upside down, that is, it pumps the heating water into the lower connection of the plate heat exchanger.
  • An important step of the invention is therefore a direct connection from the pressure side of the pump housing to Plate heat exchanger. In known boilers, however, the plate heat exchanger is mounted on the suction side of the pump housing.
  • the pump housing is connected to the plate heat exchanger by a clip attached to a male metal joint of the plate heat exchanger.
  • the pressure side of the pump housing is provided with a drain valve to drain the heating water at the lowest point of the pump housing.
  • the drain valve is designed to open and close a quarter turn and provides easy opening and a cost and space saving connection.
  • the device for generating hot water for heating and domestic purposes in buildings has a heat pump with a recirculated in a circuit 1 by a compressor 2 fluid, wherein in the circuit 1, a heat from an environmental circuit 3 receiving the first heat exchanger I, the heat a heating circuit 5 dispensing second heat exchanger II and located between the heat exchangers throttle. 7 are arranged.
  • the first heat exchanger I works as an evaporator and the second heat exchanger II as a condenser.
  • the guided through the first heat exchanger I environmental circuit 3 has a pump 8, which circumscribes the fluid in the environmental circuit 3, wherein the environmental cycle coils 9 and a heat exchanger, by / the heat from the environment, d. H. is taken from the ambient air, the soil, the groundwater or from the exhaust air of a building.
  • the guided through the second heat exchanger II heating circuit 5 has a heating water circulating pump 10 and is guided by heating surfaces forming convectors (radiators, floor heating 11), which heat a building. Further, a second heating circuit 12 is branched off at the heating circuit 5 as a bypass, which runs with a pipe coil 13 through a drinking water tank 14.
  • the pump 10 of the heating circuit 5 is connected with its outlet port 10a directly without an intermediate line at the inlet IIa of the side wall IIb of the second heat exchanger II, so that the second heat exchanger II and the pump 10 form a compact unit, as Fig. 2 shows.
  • a secure hold of the pump 10 on the heat exchanger II is given by the fact that on the side wall IIb a bolt B projects, on which a protruding on the pump housing sheet metal part 10b is screwed.
  • the direct attachment of the pump to the heat exchanger wall IIb can also be done by latching form-fitting, in particular by a clip.
  • a transmission of vibrations generated by the pump 10 to the second heat exchanger II is prevented by a damping element between the attachment of the pump and the heat exchanger.
  • a drain valve 16 is connected as a drain cock on the pressure side of the pump.
  • the heat pump 1, 2 7 is arranged with the two heat exchangers I, II and the environmental circuit 3 with its pump 8 and all valves, sensors and terminals and the heating circuit 5 with its pump 10 and all valves, sensors and terminals in a single housing 17 , On the outside of the housing 17 of the environmental leading part of the environmental cycle 3 and leading to the heating surfaces and in particular for drinking water heating part of the heating circuit 5 is connected.
  • connections and functions may be added to the pump housing, such as a pressure relief valve, a pressure sensor, 3-way valves that allow active interposition between the two suction connections, a venting chamber to separate potential air bubbles from the water flow a flow sensor is conceivable and advantageous.
  • the integrated pump housing described is also used in the environmental circuit 3 and is there directly attached to the already mentioned integration advantages on the heat exchanger I.
