Definitions

  • the present invention relates to a heat transfer station which transfers demand from heat sources at different temperature level to heat sinks having different temperature specifications as required.
  • the object of the present invention is to provide service water and heating heat as needed with the least possible energy losses.
  • FIG. 1 shows a heat transfer station 1 with a heat exchanger 2, which is connected to four terminals 3, 4, 5, 6, in which there is a first input 3, a first output 4, a second input 5 and a second output 6.
  • the first input 3 is fluidly connected via the heat exchanger 2 to the first output 4.
  • Disconnected therefrom via the heat exchanger surface of the heat exchanger 2 the second input 5 is connected in a fluid-conducting manner via the heat exchanger 2 to the second output 6.
  • a changeover valve 8 a circulating pump 9 which can be regulated in the delivery rate, and a mixing valve 10 are arranged one behind the other in a supply line 7.
  • the circulation pump 9 also has an integrated volume flow sensor.
  • the mixing valve 10 is connected to a respective connection to the second input 5, the second output 6, a first heat source supply line 11 and a second heat source supply line 12.
  • the second output 6 is connected to a heat source return line 13.
  • the switching valve 8 is connected to a respective connection to the second input 5, the supply line 7 and a heating circuit 15.
  • the second output 6 is connected to a heating circuit return 16.
  • the mixing valve 10 is always open to the second input 5, while the feeds to the second output 6, the first heat source supply line 11 and the second heat source supply line 12 continuously locked.
  • FIG. 2 shows the integration of the heat transfer station 1 with a controller 20 in a system.
  • WW hot water
  • KW fresh water
  • WW hot water
  • two heat sinks 17 are connected in the form of radiators in rooms to be heated.
  • a first stratified storage 18.1 is connected at its upper portion to the first heat source supply pipe 11 and at its lower portion to the heat source return pipe 13.
  • a second stratified storage 18.2 is connected at its upper portion to the second heat source supply line 12 and at its lower portion also to the heat source return line 13.
  • the second output 6 of the heat exchanger 2 is connected via a bypass line 19 to an input of the mixing valve 10.
  • the circulation pump 9 conveys the fluid to the heat exchanger 2, where it transfers thermal energy to service water, which flows via the fresh water supply of the inlet 3 through the heat exchanger 2 and the first outlet 4 to the hot water tapping point 14.
  • the first layer memory 18.1 is at a higher temperature level than the second layer memory 18.2.
  • the fluid, which flows to the second input 5 of the heat exchanger 2 is mixed as required in the mixing valve 10 from fluid from the first heat source supply line 11, the second heat source supply line 12 and / or return from the bypass line 17.
  • the higher the required temperature the more fluid from the first heat source supply line 11 is used, since there the highest temperature is withdrawn from the first layer memory 18.1.
  • At even lower temperatures required fluid from the second heat source flow line 12 can be mixed in the mixing valve 10 with fluid from the bypass line 19.
  • the switching valve 8 is switched such that the supply line 7 is connected to the heating circuit 15.
  • the circulation pump 9 takes over the delivery of the fluid, which leads via the heat sink 17 and the heating circuit return 16 to the heat source return line 13.
  • the circuit is analogous to the dhw requirement.
  • FIG. 3 shows a building installation with several heat transfer stations according to the invention 1.
  • Several heat transfer stations 1 have here together via a first layer memory 18.1 at a higher temperature level and a second layer memory 18.2 at a lower level.
  • a heat pump 21 has an environmental heat source 23 for transferring thermal energy from ambient air to a brine circuit 22.
  • the environmental heat source 23 may be an air heat exchanger, a geothermal heat exchanger, a groundwater heat exchanger or other source.
  • the brine circuit 22 can on the one hand serve the evaporator of the heat pump 21. On the other hand, heat can also be transferred from the brine circuit 22 to the second stratified storage 18.2 via a brine heat exchanger 24.
  • heat from a radiator which then acts as a heat sink 17 can be transmitted via a heat transfer station 1 to the second layer storage 18.2.
  • the stored heat can later be used again via the heat transfer station 1 for domestic water heating. If the stored heat can not be used meaningfully, the heat can be transmitted via the brine heat exchanger 24 to the brine circuit 22 and discharged into the environment heat source 23, for example an air heat exchanger to the environment.
  • the heat pump 21 can also be used with inverted process control as Klimaanalage; In this case as well, heat can ultimately be released to the environment via the environmental heat source 23, which in this case is a heat sink.
