Definitions

  • the invention relates to the heating/air conditioning installations that equip certain vehicles, such as automobiles, as well as certain buildings.
  • certain heating/air conditioning installations include reversible heat pumps that are able to work both in a heating mode as well as in a cooling mode.
  • they comprise an internal condenser which, in the heating mode, contributes towards heating of interior air by exchange with a heated and pressurized refrigerant fluid, and an external evaporator which, in the heating mode, heats the cooled and depressurized refrigerant fluid by exchange with exterior air.
  • a first solution which is most notably described in the French Pat. No. FR 2525330, consists of associating conduits to the external evaporator that are dedicated to de-icing in which a heat transfer fluid coming from the cooling circuit (for example, from a vehicle motor) circulates.
  • the disadvantage of this first solution lies in the fact that this requires an important modification of the external evaporator.
  • a second solution most notably described in the British Pat. No. GB 988874, consists of implanting the external evaporator within the same housing as the internal condenser, in such a manner that the external evaporator can be heated due to the refrigerant liquid that is circulating in the internal condenser.
  • the disadvantage of this second solution lies in the fact that it is exceedingly inconvenient, or even impossible to implement in an automobile and has a negative impact on overall performance.
  • a third solution that is notably described in the U.S. Pat. No. 5,586,448 consists in the use of an additional electric radiator for the heating of a heat transfer fluid which circulates through the external evaporator.
  • the disadvantage of this third solution lies in the fact that it requires not only a modification of the external evaporator, but also an additional electric heating device, which reveals itself to be very cumbersome and energy hungry (which is penalizing as regards range in the case of an electric or hybrid vehicle).
  • the object of the invention is therefore to propose a heating/air conditioning installation that does not present all or parts of the aforementioned disadvantages.
  • a heating/air conditioning installation or system that comprises:
  • the heating/air conditioning installation can also feature other characteristics that can be taken either separately or in combination, and more in particular:
  • the invention furthermore proposes a vehicle, such as an automobile, which features a heating/air conditioning installation of the type described here above.
  • FIG. 1 illustrates a first embodiment in a schematic and functional form of a heating/air conditioning installation, in heating mode
  • FIG. 2 illustrates a second embodiment in a schematic and functional form of a heating/air conditioning installation, in heating mode
  • FIG. 3 illustrates, in a schematic and functional form, the heating/air conditioning installation of FIG. 1 , in refrigeration mode.
  • the purpose of the invention is that of proposing a reversible heat pump heating/air conditioning installation (IC).
  • the heating/air conditioning installation belongs to an automobile, such as for example, a car, such as the “full electric” or “hybrid” type.
  • the invention is not limited to this application. It does in fact involve any reversible heat pump type heating/air conditioning installation, no matter whether it is destined to be installed in a vehicle or a building.
  • FIGS. 1-3 Two embodiments of heating/air conditioning installations IC, according to the invention, are schematically represented in FIGS. 1-3 .
  • the first embodiment, illustrated in FIGS. 1 and 3 is, for example, destined to be installed in an electric automobile or in a building.
  • the second embodiment, illustrated in FIG. 2 is for example destined to be implanted in a hybrid automobile.
  • the heating/air conditioning installation IC is destined to work, as required, in heating or refrigeration mode.
  • it features a compressor CP, an internal condenser CDI, an external pressure reducer DTE, an external evaporator EE, and an external condenser CDE that all are used, at least, in the heating mode.
  • the compressor CP heats and pressurizes a refrigerant fluid which, in heating mode, comes from the external evaporator EE.
  • the internal condenser CDI is only used in the heating mode. It contributes to the heating of the interior air (which here comes from the interior of the vehicle cabin) by exchange with the refrigerant fluid transformed into hot and pressurized gas by the compressor CP. At its outlet, it delivers a refrigerant fluid in liquid phase that has been partially cooled during exchange with the interior air.
  • the internal condenser CDI is of the gas/air type. It is therefore used to heat the interior air which passes through it by exchange with the refrigerant fluid (hot and pressurized gas) which circulates in its conduits or between its stacked panels.
  • the internal condenser CDI is of the gas/liquid type. It therefore heats a heat transfer fluid, which circulates in some of its conduits or between certain parts of its stacked panels and which comes from a cooling circuit, by exchange with the refrigerant fluid (hot and pressurized gas) which circulates in certain other of its conduits or between certain other parts of its stacked panels.
  • This heated heat transfer fluid then returns to the cooling circuit to feed a pump PE, which feeds an air heater AR which, in heating mode, heats the interior air which passes through it by exchange with the heated heat transfer fluid.
  • the heat transfer fluid which flows out of the air heater AR feeds the portion of the cooling circuit which passes through the motor MR and which feeds the internal condenser CDI.
  • air heater is understood to mean an air/liquid heat exchanger. Furthermore, one will note that the air heater AR can form part of the installation IC.
  • the external pressure reducer DTE is only used in the heating mode. It cools and depressurizes the refrigerant fluid which comes from the external condenser CDI, before it feeds the external evaporator EE. It delivers a depressurized and cooled liquid.
  • the external evaporator EE is only used in the heating mode. It is used in heating the refrigerant fluid (depressurized and cooled liquid) which comes from the external pressure reducer DTE, by exchange with the exterior air (cold), which is to say absorption of heat contained in the exterior air. It delivers a refrigerant fluid at the outlet, in gaseous and lightly heated phase, which is destined to feed the compressor CP.
  • the external condenser CDE is contiguous with the external evaporator EE.
  • contiguous is understood to be the fact of being in contact with the external evaporator EE, or in the immediate vicinity of the external evaporator, most typically within a few centimeters, or rather interlocked in the external evaporator EE.
  • the external condenser CDE in heating mode, collects the refrigerant fluid, which comes from the internal condenser CDI, so as to feed together with this refrigerant fluid, the external pressure reducer DTE and constitutes a heat source for the contiguous external evaporator EE.
  • this source of heat (which is made up of the external condenser CDE) is such that it will reduce the probability that the external evaporator EE will ice up in the presence of an exterior air whose temperature is low.
  • reducing the probability of icing is understood to be the fact of limiting, as much as is possible, the creation of icing as regards the external evaporator EE.
  • icing up will only be able to occur in the presence of a low exterior temperature, with a high level of humidity and a low exterior air speed.
  • the heating of the external evaporator EE can be undertaken by thermal conduction, in the case of an interlocking, or mechanical contact, with the external condenser CDE, and/or by means of the exterior air which has been heated during its passing through the external condenser CDE (which requires that the external condenser be placed upstream of the external evaporator EE vis-â-vis the flow of exterior air, as illustrated).
  • the external condenser CDE and the external evaporator EE may constitute two contiguous sub-units (preferably, interlocking) of a single heat exchanger or two independent and contiguous heat exchangers.
  • the external condenser CDE may also function in the cooling mode.
  • the installation must also include an internal pressure reducer DTI and an internal evaporator EI, as illustrated in FIGS. 1-3 .
  • the internal pressure reducer DTI is only used in the cooling mode. It cools and pressurizes the refrigerant fluid (in liquid phase), which comes from the external condenser CDE, before it arrives at the internal evaporator EI.
  • the internal evaporator EI also is only used in the cooling mode. It is used to cool the interior air which passes through it by thermal exchange with the cooled and depressurized refrigerant fluid (in liquid phase) which comes from the internal pressure reducer DTI.
  • the external condenser CDE is used to pre-cool the refrigerant fluid (hot and pressurized gas), which comes from the compressor CP, by thermal exchange with the exterior air, so as to feed the internal pressure reducer DTI with pre-cooled refrigerant fluid (in liquid phase).
  • the heating/air-conditioning installation can include at least one of the three-way valves Vj, that are described here-below:
  • the installation IC can optionally include one or more dehydrating reservoirs RD 1 , RD 2 .
  • the installation IC features a first dehydration reservoir RD 1 positioned between the first inlet/outlet of the external condenser CDE and the inlet of the external pressure reducer DTE, and a second dehydration reservoir RD 2 positioned between the second inlet/outlet of the external condenser CDE and the inlet of the internal evaporator EI.
  • the mode of heating of the installation IC is symbolized by arrows in FIGS. 1-2 .
  • the refrigerant fluid circulates from the compressor CP towards the internal condenser CDI where it is used ( FIG. 1 ) or simply contributes ( FIG. 2 ) to the heating of the interior air by thermal exchange.
  • the first valve V 1 is then configured in such a way that the refrigerant fluid is directed towards the internal condenser CDI.
  • the refrigerant fluid goes from the internal condenser CDI towards the external condenser CDE, by way of the second valve V 2 which is configured for this purpose. It then heats the contiguous external evaporator EE and thereby permits that it is either not or only slightly iced up.
  • the refrigerant fluid goes from the external condenser CDE towards the external pressure reducer DTE, by way of a third valve V 3 which is configured for this purpose. It is then partially cooled and depressurized. Then, the refrigerant fluid goes from the external pressure reducer DTE towards the external evaporator EE where it is cooled by thermal exchange with the exterior air. Lastly, the refrigerant fluid goes from the external evaporator EE towards the compressor CP where it is transformed in to heated and pressurized gas, by way of a fourth valve V 4 which is configured for this purpose.
  • the cooling mode of the installation IC is symbolized by arrows in FIG. 3 .
  • the refrigerant fluid circulates from the compressor CP towards the external condenser CDE where it is partially cooled by thermal exchange with the exterior air.
  • the first valve V 1 and the third valve V 3 are configured for this purpose.
  • the refrigerant fluid goes from the external condenser CDE towards the internal pressure reducer DTI where it is cooled and depressurized, by way of the second valve V 2 which is configured for this purpose.
  • the refrigerant fluid goes from the internal pressure reducer DTI towards the internal evaporator EI where it cools the interior air that passes through the same (EI) by thermal exchange.
  • the refrigerant fluid goes from the internal evaporator EI towards the compressor CP where it is transformed in heated and pressurized gas, by way of the valve V 4 which is configured for this purpose.
  • the invention offers a certain number of advantages, amongst which:
  • the invention does not limit itself to methods of execution of the heating/air conditioning installation and of the vehicle described here above, in a non-exhaustive manner, but rather encompasses all variants that could be foreseen by the person skilled in the art within the framework of the claims that follow.
