Definitions

  • the invention relates to an air heat pump evaporation device for an air heat pump heating according to the preamble of claim 1 and to a method for operating an air heat pump heating with an air heat pump evaporation device according to the preamble of claim 11.
  • heat pumps are used as heat pump heaters to bring heating water to a desired temperature.
  • the energy required by a heat pump for this purpose is met by about one third of the electricity it derives from the electricity grid and the rest, ie its largest share, from the free heat that occurs naturally. This not only has the advantage that the operating costs can be kept relatively low, the operation of a heat pump heating is also particularly environmentally friendly.
  • Known types of heat pump in which a working fluid is circulated, are the compression heat pump and the absorption heat pump.
  • a refrigerant circulates in a circuit which, driven by a compressor or compressor, alternately assumes the states of matter liquid and gaseous.
  • Absorption heat pumps have a mechanical instead of a mechanical one thermal compressor and use the physical effect of the heat of reaction when mixing two liquids or gases.
  • the absorption heat pumps have a solvent circuit and a refrigerant circuit, whereby the solvent in the refrigerant is repeatedly dissolved or expelled.
  • groundwater and soil energy sources must be costly to open up for the installation of geothermal probes, geothermal collectors etc., but due to the relatively constant temperatures in the ground at a few meters depth or in the groundwater, satisfactory performance figures of more than four (soil) or even more than five (soil) Groundwater).
  • an air heat pump heating with outside air as a heat source is much cheaper because no costly development and construction work is required here.
  • the outdoor air as a heat source has the disadvantage in German latitudes and latitudes with comparable climatic conditions that the temperature of the outside air is subjected to very large fluctuations both during the day and during the year, so that the coefficient of performance of such an air heat pump over the groundwater heat pumps and the Soil heat pumps a much lower Has a coefficient of performance of about 2.5. Because of these large temperature fluctuations in the course of the day and year in air heat pump heaters, these are regularly with an additional heating, z. As an electric heating sword, combined to ensure the occurrence of very cold periods a sufficient heating supply. This additional use of electricity again reduces the coefficient of performance of an air heat pump.
  • solar panels are arranged on a house roof, circulated through the piped water, which is heated by the solar energy absorbed by the solar panels.
  • the water thus heated is then intermediately stored, for example, in heat accumulators designed as stratified storage tanks, from which hot water can then be withdrawn.
  • the object of the invention is therefore to provide an apparatus and a method for an air heat pump heating available, with the simple and inexpensive and environmentally friendly way an air heat pump heating operation can be performed with high performance figures.
  • an air heat pump evaporation device for an air heat pump heating in which an air heat exchanger assembly as a multiple (in the sense of at least triple) heat exchanger assembly is additionally flowed through by at least one further heat-emitting medium of a further heat source, said at least further heat-emitting medium of the air and / or the working medium, which is preferably a refrigerant, supplies heat.
  • These Supply of heat may be effected in dependence on a predetermined by means of a control and / or regulating device of an air heat pump heating mode of operation.
  • z. B. depending on certain predetermined operating parameters of an air heat pump heating but also be provided that the z. B. sucked outside air is vaporized solely by the other heat-emitting medium, whereby even the drive energy of a fan or fan can be saved.
  • a combination is possible in such a way that both the air and the working medium are heated by the additional heat-emitting medium, which likewise has a positive effect on the evaporation process and thus the energy to be expended in heat pump operation.
  • Another significant advantage of such a device according to the invention is that this also an excellent deicing of the evaporation device, for. B. in conjunction with a solar system as the other heat-emitting medium providing additional heat source, can be effected. So z. B. form ice at evaporator temperatures around 0 ° C. This ice is eliminated in conventional dual-air heat exchanger assemblies by a momentary reversal of the refrigeration cycle, which requires the use of electrical energy and thus is very expensive. In the apparatus according to the invention, however, this defrosting process can be performed by the solar system itself or the solar panels, and indeed already at collector temperatures that are little above 0 ° C.
  • an air heat pump heating can be provided with sufficiently high performance figures, wherein also the investment costs despite the provision of a further heat source for providing a further heat-emitting medium, for. B. in the form of a solar system, are significantly lower than comparable performance numbers having soil or groundwater heat pumps.
  • the problem of evaporator icing is solved much better.
  • the multiple heat exchanger assembly is designed as a triple heat exchanger assembly, which is traversed by the air as a first heat source, the working medium and a single further heat-emitting medium of the second heat source.
  • the working medium can be guided here in a tube-bundle-like first tube register and the further heat-emitting medium in a second, tubular bundle-like tube register, said first and / or second tube register Depending on the specific structure of the device according to the invention then more or less can be flowed around by the sucked air.
  • the further heat-emitting medium leading second pipe register is fluidly arranged before the working medium leading first pipe register is arranged.
  • These two pipe registers can also be integrated for a very good heat transfer between the individual media in a disk set of a plurality of individual and spaced apart slats.
  • the disk pack itself can z. B. made of a copper material or even made of an aluminum material.
  • a fan or ventilator device can be integrated into this structural unit, by means of which a directed air flow can be generated by the multiple heat exchanger arrangement.
  • This fan device is preferably arranged with respect to the two tube registers, that the air sucked in by the fan device flows around the tube register in a predetermined air flow direction.
  • this fan device is also designed to be switched off, so that, as has already been discussed above, evaporation of the working medium may also be effected solely by the additional heat-emitting medium can be done.
  • the fan or ventilator device can also be provided as a separate component in addition to the tube registers integrated in a structural unit.
  • a heat exchanger assembly possible, in which all media, ie air, working medium and additional heat-emitting medium, are guided in separate units, as long as only an efficient heat transfer between the units is ensured.
  • the additional or additional heat-emitting medium is preferably a liquid coming from a solar system as a further heat source, preferably heated to a certain predeterminable temperature.
  • the further heat-emitting medium can also be a liquid coming from a geothermal collector or a geothermal probe or a groundwater probe. It goes without saying that the additional heat-emitting medium always has to have such a temperature that, depending on the respective operating mode of the air heat pump heating, a heat transfer from this additional heat-emitting medium to the sucked air and / or the working medium is possible.
  • Such an air heat pump evaporation device is particularly inexpensive and easy to integrate into a compression air heat pump heating, which has at least one compressor and at least one expansion element.
  • the further or additional heat-emitting energy is used by a solar thermal system as a further heat source
  • Medium-forming liquid stream passed to the triple heat exchanger assembly which is preferably branched off from a guided to a buffer or stratified storage, heated liquid flow.
  • the high temperatures of the solar system can also be delivered via a switching valve in the solar circuit directly to the buffer or hot water tank.
  • both compression heat pumps and absorption heat pumps with air as the heat source can be effectively operated in an effective manner, in particular in connection with a building heating or hot water preparation.
  • a refrigerant is conducted as a working medium in a coolant circuit 2.
  • a compressor 3 driven, for example, by means of an electric motor, which is not shown here, is arranged downstream of which a condenser 4 is connected downstream.
  • an expansion valve 5 Downstream of the condenser 4, an expansion valve 5 is arranged in the refrigerant circuit 2, downstream of which a triple heat exchanger 6 downstream of the air heat pump evaporator is connected downstream.
  • the triple heat exchanger 6 is associated with a fan 7, by means of the outside air can be sucked through the triple heat exchanger 6 through, as shown in Fig. 1 only schematically by the two air arrows 8.
  • the triple heat exchanger 6 has on the fan side a refrigerant tube register 9 which, viewed in the air flow direction, is behind a solar fluid tube register 10 is arranged, wherein the two tube registers 9, 10 are combined in a built-up of a copper material or an aluminum material plate pack 11 in a conventional manner to form a structural unit.
  • a dashed "dividing line" is shown in FIG.
  • the two tube registers 9, 10 are flowed through in direct current, as shown in FIG. 1 can be removed and at the same time from the outside air, shown by the air arrows 8, flows around.
  • the solar fluid tube register 10 is traversed by a solar fluid, which is a partial flow 12 of one of a z. B. arranged on the roof of a building not shown here solar system 13 heated water flow 14 is subtracted.
  • the heated by means of the solar system 13 water is stored in a stratified storage tank 15, from which a return 16 is again guided to the solar system 13. In this return 16 of the triple heat exchanger 6 flowing through partial flow 12 is also fed again.
  • a water return 17 is led to the condenser 4, where the cooled water is reheated and recycled as a feed 18 to the stratified storage tank and stored there.
  • a partial flow of this flow 18 can also directly into a building heating, z. B. a floor heating 19 are passed.
  • a return 20 of this floor heating can, as is shown here only by way of example, are fed into the return line 17 from the stratified storage tank 15 to the condenser 4.
  • Fig. 1 can be further removed, starting from the stratified tank 15 and hot water or cold water to a mixing valve of a z. B. shower 21 are guided, but what will not be discussed in more detail here.
  • both the sucked by the fan 7 air stream 8 is preheated to outside air or also finds a heat input via the disk set takes place in the refrigerant pipe register 9, so that an effective evaporation of the refrigerant in this triple heat exchanger 6 takes place by the preheated outside air-air flow and the heat input into the refrigerant pipe register 9, which then in the compressor 3 with relatively little power consumption to a high Pressure can be compressed.
