Definitions

  • the invention relates to a heating device with a heating circuit and a heating system located therein, in particular an oil or gas heating system, with an exhaust gas duct in which the evaporator, which can be acted upon with the support of a blower, optionally by exhaust gas, exhaust gas / outside air mixture or outside air a refrigerant-circulating heat pump is arranged to exchange heat, the condenser of which is heat-exchanging in the heating circuit.
  • Such a heating device is known from DE-A-2 647 216. It has the advantage that heat energy can be recovered from the flue gases of the heating furnace with the help of the heat pump, and that the heat pump can cover this alone - without using the heating furnace - with a relatively low energy requirement of the heating circuit.
  • the invention is based on the knowledge that these problems can be eliminated in a (at least) bivalent operated heat pump as easily as suddenly by an independent of the temperature of the outside air and only load-dependent connection of the heating device. Accordingly, it consists in that a control unit switches on the heating system depending on the pressure (or the temperature) of the refrigerant in the evaporator when the pressure (or the temperature) falls below a predetermined lower limit and when the pressure (or the temperature) exceeds a predetermined limit. Temperature). If the pressure of the refrigerant in the evaporator of the heat pump is low, the control unit switches on the heating device so that the heating circuit and thus the condenser of the heat pump quickly reaches the optimal temperature of approx. 30-40 ° C for heat pump operation.
  • the volume throughput of the fan can preferably be regulated and is reduced when the heating is switched on. If the evaporator of the heat pump is only exposed to outside air, then a volumetrically much higher throughput is required than when operating with an exhaust gas or exhaust gas / air mixture. If the requirement of the fan, which is required in both cases, were fixed to one operating state, the heat pump could not work optimally in the other operating state.
  • a further development of the invention is that a further control device is provided which, depending on the refrigerant pressure in the condenser of the heat pump, switches off the circulating pump of the heating circuit when the pressure falls below a certain minimum.
  • the control of the circulation pump not by a thermostat that records the room or outside temperature, but by the pressure in the heat pump condenser ensures the adaptation of the heat pump state to the heating circuit and prevents, for example shows that the circulation of the heating circuit is interrupted, although the heat pump circuit needs the heat exchange in the condenser.
  • Fig. 1 shows a heating kettle) 1 with the associated heating, not shown in detail.
  • the heated in the boiler 1 heat transfer medium usually water, flows through the heating circuit 2, in which a plurality of radiators 3 are turned on; only a single radiator is shown in the present case.
  • a circulation pump 4 ensures the forced circulation of the heat transfer medium.
  • the flue gases from the heating system are released through the flue gas duct 6. Of the building in which the heating system is arranged, only the roof 7 is indicated.
  • An adjustable flap 8 in the exhaust duct 6 makes it possible to direct the exhaust gas into a branch 9 through the evaporator 12 of a heat pump 13 described below and a further branch 10 back into the exhaust duct 6.
  • a connection 19 in which there is an adjusting flap 21 ambient air can be led into the branch 9 via the opening 20 and admixed with the exhaust gas flowing to the evaporator 12.
  • a fan 22 in the branch 10 ensures the required flow of the exhaust gas or the exhaust gas / air mixture.
  • the fan 22 is advantageously speed-controllable, so that it produces a substantially higher, for example 10 times the throughput in pure air operation than in exhaust gas / air operation. Furthermore, a return line 29 for cold air (or cold air / exhaust gas mixture) branching off behind the blower 22 can be provided in the connection 19; the control flap 21 is designed and arranged such that it opens either the fresh air or the cold air supply to the opening 20.
  • the heat pump 13 also includes a compressor 14, a condenser 15 and an expansion valve 16. With the associated pipelines, these components form a secondary circuit which is filled with a refrigerant which is circulated by the compressor 14.
  • the refrigerant heated in the evaporator 12 flows through the pipeline 17 into the compressor 14.
  • the temperature rises sharply.
  • the condenser 15 which is in heat exchange connection with the heating circuit 2
  • the heat of the refrigerant is largely given off to the heat transport medium circulated in the heating circuit 2.
  • the refrigerant in the expansion valve 16 expands, it cools down strongly, so that the refrigerant is ready to absorb heat again in the evaporator 12.
  • the temperatures in the evaporator are usually 0 to + 5 ° C, in the condenser 80 to 90 ° C.
  • a valve arrangement is designated, through which a short-circuit connection 26 of the flow and return of the heating circuit 2 can be effected if the heating of the heating circuit 2 takes place only by such heat that the heat pump 13 draws the ambient air drawn in through the connection 19 from the blower 22 .
  • FIG. 1 shows - albeit schematically - the design of a heating device with the features that can be seen in FIG. 1.
  • the same parts have the same reference numerals and do not require a new explanation here. Deviations and additions are described below.
  • the flow is denoted by 5 'and the return by 5 "; the dashed line 30 indicates what belongs to a heating device according to the invention of simple construction and can be set up as a compact unit at the place of use.

  • the evaporator 12 of the heat pump 13 is supported on the upper frame 31.
  • a drip tray 23 which collects condensed water and condensed pollutants.
  • the exhaust duct is reduced to an exhaust nozzle 6 '. Otherwise, the exhaust gas duct continues in a connecting line 11, which surrounds the exhaust pipe 6 ′ with an enlarged section 11 ′ in such a way that ambient air enters the connecting line 11 according to the arrows 18 and there - if the burner 38 is in operation - can mix with the exhaust gas.
  • the air (or the exhaust gas / air mixture) accelerated by the blower 22 comes out of the building through the outlet connection 24 in the building wall 25.
  • a chimney is not required because the gas that has escaped has cooled down and been cleaned.
  • FIG. 3 has been expanded compared to that in FIG. 2 by numerous additional devices for the purpose of multivalent heat use. Again, the same parts are identified by the same reference numerals as in the previous figures. This also applies to FIG. 4, which in terms of circuitry illustrates the structural design of the heating device shown in FIG. 3.
  • the blower 22 arranged in the outlet connection 24 also sucks either air according to the arrows 18 or air and additionally exhaust gas according to the arrows 18 'into the connecting duct 11 and through the evaporator 12 of the heat pump.
  • an inlet 56 is provided through which warm external air (for example from a swimming pool) can be supplied.
  • a heat exchanger 48 is provided which is acted upon on the primary side via a line 59 by a heat transfer medium heated by solar energy (in a manner not shown here). The air entering according to arrows 18 can thus be preheated.

  • the heat exchanger 48 is only acted on when only solar heat of a low temperature level is available.
  • the solar heat is fed directly to the domestic water (hot water); this is not shown in FIG. 3, but is indicated in FIG. 4.
  • the heat transport medium in question is fed via line 41 to a heat exchanger 40 which is acted upon on the secondary side by the return 5 "of the heating circuit 2, which then enters and leaves the condenser 15 of the heat pump this at its connection to a heat exchanger 42, which is also in the heat pump circuit and which carries domestic water via line 43 on the secondary side.
  • the refrigerant circulated by the compressor 14 in the heat pump circuit arrives after leaving the condenser 15 into a collector 28 and from there into a heat exchanger 44 which, with the aid of a blower 46 according to the arrows 47, the ambient air or - with the aid of a pipeline (not shown) - the air in one warmed another room.
  • a branch 51 is provided, which leads via an expansion valve 16 'to an evaporator 12' only shown in FIG. 4.
  • the return line bears the reference number 52.
  • the circulation pump 55 in the heating circuit 2 is controlled by a pressure switch 57, which measures the pressure (or the temperature) in the condenser 15 via the line 58 and switches the circulation pump 55 off when the pressure falls below a certain minimum pressure in the condenser 15.
