  • the intermediate medium line 10 has a branch from which a line 24 branches off, likewise there is a branch in the line 11 in which a line 25 opens into the line 11. While the line 10, the intermediate medium in the cooled to was conveyed from the supply air heat exchanger 12 into the exhaust air heat exchanger 21, the exhaust gas heat exchanger 20 is hydraulically connected in parallel to the exhaust air heat exchanger 21 through the lines 24 and 25.
  • the fuel-heated heat source 2 is located in the room 30 and is connected via the exhaust pipe 6 to the exhaust gas heat exchanger 20, which is connected directly to the chimney 9.
  • a vent 3 is provided, which is connected via a guide 4 to the exhaust air heat exchanger 21, which conveys the exhaust air into the atmosphere via a special pipe 31.
  • the supply air duct 22 is also provided, which runs through the supply air heat exchanger 12 and heats a space 32 via a heating line 23, which is connected via a line 33 to the atmosphere as a vent.
  • the routing of the intermediate medium differs from the previous examples according to FIGS.
  • FIG. Four shows that a heat pipe 37, one end 38 of which can be used as the heat exchange element for the heat transfer device is acted upon by the combined exhaust gas / exhaust air heat exchanger 8, while the other end 39 is assigned to the supply air heat exchanger 12.
  • the heat pipe has a liquid which is evaporated in the end 38 under the action of heat supplied.
  • the steam reaches the end 39 and condenses on account of the heat given off to the supply air brought in in the duct 22.
  • the condensed heat transfer medium flows back to the end 38 at the bottom of the heat pipe due to a slope or pumping action, and the cycle begins again.
  • the supply air heat exchanger 12 is divided into several sections that have no connection with one another.
  • the supply air duct 22 is led to a separation point 40, from which individual supply air lines 41, 42 and 43 depart, which are supplied via separate heating lines 44 45 and 46 to different rooms 47, 48 and 49 to be heated with hot air.
  • the rooms 47 to 49 can be those in which fuel-heated heat sources are installed or which in turn are to be vented by a venting device 3.
  • the figure six teaches that instead of a single intermediate circuit, two intermediate circuits 50 and 51 can be provided, each having lines 10 and 11. It is advantageous here to assign one intermediate medium circuit to the exhaust air heat exchanger 21 and the other to the exhaust gas heat exchanger 20.
  • the common supply air line 22 is again led to the separation point 40, from which channels 41 and 42 branch, which lead to a supply air heat exchanger split into two elements 52 and 53. It is provided that the supply air heat exchanger element 52 is connected to a room 49 via a heating line 44, while the supply air heat exchanger element 53 is connected to the other room 48 via a heating line 45. Both rooms 48 and 49 can be vented via separate vent lines 33. It is also possible to vent these rooms via the ventilation device 3.
  • FIG. Seven a construction of the circuit according to FIG. 6 is possible to lead the supply air in parallel instead of from the separation point 40 in such a way that basic heating of the supply air takes place in a basic heating heat exchanger element 54 and that the separation point 40 lies at the outlet of this basic heating element.
  • a heating duct 46 is then led to the basic heating element directly to a room 47, another heating duct is guided via the post-heating element 55, the output line 56 of which is supplied either in the same room 47 or another room to be heated with hot air.
  • the exhaust air from the room 47 is discharged via the ventilation device 3.
  • the heated fresh air is only partially reheated in the exemplary embodiment according to FIG. Seven, a complete two-stage heating of the fresh air is provided in the exemplary embodiment according to FIG. So the Zu opens Air duct first in the basic heating element 54, but the heating line 44 is looped through the post-heating element 55, so that a two-stage heating of the fresh air or the circulating air is possible.
  • a memory 60 is provided as an essential element, which is connected via lines 11 and 10 to the exhaust gas heat exchanger 20, which is fed by the fuel-heated heat source 2 via the exhaust pipe 6.
  • the exhaust pipe 6 located downstream of the exhaust gas heat exchanger 20 is still looped through the exhaust air heat exchanger 21, which is otherwise fed by the vent 3 through the guide 4. Exhaust gas and exhaust air leave the exhaust air heat exchanger 21 via the chimney 9.
  • An intermediate circuit 50 with lines 10 and 11 feeds the supply air heat exchanger 12, to which supply air is supplied via the duct 22.
  • Two heating lines 44 and 45 leave the supply air heat exchanger 12, one of which is fed directly to a space 47 to be heated, while the other is guided via a storage heat exchanger 61.
  • An output line 62 of the storage heat exchanger likewise leads to room 47 or to another or more rooms.
  • the storage heat exchanger is connected via lines 63 and 64 to the storage 60, which may be designed as a domestic water storage. There is thus the possibility of charging the accumulator 60 from the exhaust gas heat exchanger 20 via the intermediate circuit 51 if, for example, a heat source has to be in operation. but no warm air heating in room 47 is desired.
  • the storage heat exchanger 61 it is possible to apply the charged content of the storage 60 to the storage heat exchanger 61 via the lines 63 and 64 if air heating in the room 47 is desired, but at this time there is no waste heat from the ventilation 3 or from fuel-heated heat sources or that the waste heat supply is not sufficient.
  • the intermediate medium circuit 50 it is possible via the intermediate medium circuit 50 to act on the supply air heat exchanger 12 via the heat exchanger 21, so that the storage heat exchanger 61 in one case represents after-heating as a second stage for the fresh air supplied via the lines 44 and 62, or that at Failure of an exhaust air preheating of the fresh air of the storage heat exchanger 61 takes over the heating of the supplied fresh or possibly recirculated air alone and in one step.
  • the exhaust air heat exchanger 21 Since it is not readily apparent to the system designer how high the temperature level of the exhaust gas in line 65, which has already cooled down in the first stage, it is expedient to provide the exhaust air heat exchanger 21 with a plurality of taps. It is now possible to connect the line 65 to one of the taps 66 to 68 after the system has been created and adjusted. The tap for the connection is then selected, in which the temperature level of the exhaust gas corresponds approximately to the temperature level of the exhaust air temperature level, which has already cooled down in the heat exchanger 21. This case is therefore chosen when the temperature level in the exhaust pipe 65 is lower than the temperature level of the exhaust air in the guide 4 on the inlet side of the exhaust air heat exchanger. If, however, the temperature level of the exhaust gas in line 65 is higher than the temperature level of guide 4, line 65 is connected directly to line 4 or to the inlet point. on the heat exchanger 21.
