Definitions

  • the invention relates to a heat exchanger panel for temperature control of a room and a method for temperature control of a room with such a heat exchanger panel.
  • the device includes a heat sink that has a surface facing the room. The surface is brought to a lower temperature than the room using the heat sink.
  • the heat sink is implemented, for example, by cooling pipes. Water, a water/glycol mixture or refrigerant can flow through the cooling pipes. Instead of the cooling tubes, electrically cooled components, for example via Peltier elements, can also be provided.
  • the device comprises a surface element between the surface and the room. The surface element is designed to be almost tight or impermeable to room air and water vapor, but transparent to heat radiation.
  • the dehumidification device can be, among other things, a sorbent and/or a heating device and/or a fleece.
  • the fleece is applied to the entire surface of the heat sink and extends over the sides of the heat exchanger device into a rear area in order to dry there.
  • the problem here is that if the fleece is arranged over the entire surface, large amounts of water will accumulate, leading to an uncontrolled condition. As a result, the moisture is not always dissipated into the rear area of the heat exchanger device as intended, but can partially remain in the device remain. This degrades the performance of the heat exchanger device and can lead to long-term damage to the device. Since such a heat exchange device should be designed for continuous operation over a long period of time, this is a serious problem.
  • an air cooling and water condensate removal device which comprises a thin plate.
  • the plate has a fine, wettable, serrated or porous surface on one side.
  • the opposite side of the panel is thermally insulated.
  • a cooling plate for example with a circulating liquid coolant, is arranged inside the plate. The coolant cools the wettable surface so that moisture from the air condenses. The resulting condensate is drained off using capillary systems.
  • a radiant air conditioning device is described in CN 111 912 066 A.
  • the radiant air conditioning device includes an energy transfer layer facing away from the room, a damping layer and a radiation panel facing the room.
  • the energy transmission layer is in thermal contact with the radiation panel via the damping layer and with it the temperature of the radiation panel can be changed.
  • An adjusting device is provided with which the thickness of the damping layer can be adjusted. This allows the temperature of the radiation panel to be adjusted precisely.
  • a heat exchanger panel which comprises a heat exchanger.
  • the heat exchanger has a medium line for guiding a heat exchange medium from a medium inlet to a medium outlet and a heat-conducting heat exchanger wall which is connected to the medium line.
  • the heat exchanger wall forms an interface facing a room, which can be brought to a lower temperature than a heat load.
  • At least one surface element is arranged between the interface and the room, which is at least partially permeable to thermal radiation and almost impermeable to air, so that an almost airtight space is formed between the interface and the surface element.
  • the heat exchanger panel is characterized in that in the area adjacent to the medium inlet, a condensation cavity is formed adjacent to the medium line and on the side facing away from the heat exchanger wall with respect to the surface element, and the heat exchanger wall has at least one opening, so that the intermediate space is communicatively connected to the condensation cavity.
  • a capillary material is arranged in the condensation cavity or at least one capillary-active element is provided, which is guided to an outer surface of the heat exchanger panel, so that liquid condensing in the condensation cavity is transported to the outside due to the capillary action of the capillary material or the capillary-active element in order to dry there.
  • the condensing cavity is a cavity in the sense that it is free of other bodies so that air can enter it and the moisture contained therein can condense.
  • the heat exchanger panel described has the heat exchanger and the space formed between the interface of the heat exchanger wall and the surface element. In a theoretical and idealized structure of the heat exchanger panel, this space is completely sealed, so that there is no exchange of air and no entry of water vapor in the event of a vapor pressure gradient with the environment. In practice, this is very difficult to achieve, which is why there is almost always an exchange of air, entry of water vapor and thus entry of moisture.
  • the heat exchanger panel Since the heat exchanger panel is stressed during operation by a temperature difference between the cold interface and warm room air, over time air moisture accumulates in the gap, which condenses on the cold interface. It should also be taken into account that such a heat exchanger panel will be used in continuous operation over a long period of time.
  • the main transport mechanism for the entry of moisture is water vapor diffusion due to the partial pressure gradient in different climates. The water vapor partial pressure in the room is higher than that in the space between.
  • WO 2016/207141 A2 shows a heat exchanger panel in which a fleece is arranged along an interface of the heat sink and extends outwards and can transport moisture to the outside.
  • this known heat exchanger panel does not have one Condensation cavity so that air can collect in it and cool down, so that the moisture contained in the air condenses.
  • the capillary material can be a fleece or a woven fabric or a sorptive material.
  • the capillary material can be, for example, a polymer film, in particular a polyamide film or a polyester film.
  • capillary material refers to materials that are fundamentally capable of absorbing liquids, in this case water.
  • the materials are also characterized by the fact that they have pores, a structure being formed by the pores, whereby the liquids move inside the material primarily due to capillary forces.
  • Capillary tension is a special form of surface tension.
  • the pores can be macroscopic pores or microscopic pores at the molecular level, such as hollow fibers in a polyamide or a polyester film.
  • a polyamide film is a smooth, pore-free film. However, it has very small pores, which are suitable for absorbing water and cause water to spread throughout the film. With such small pores, molecular interactions can also influence the spread of water in the film.
  • capillary channels are incorporated into the heat exchanger wall, so that no fleece or fabric is necessary.
  • the heat exchanger wall additionally forms the capillary material and leads to an outer area of the heat exchanger panel.
  • the capillary channels can, for example, be incorporated into the surface of the heat exchanger wall using a laser.
  • the capillary channels are preferably introduced into the surface of the heat exchanger wall facing the condensing cavity and only into the heat exchanger wall up to the condensing cavity.
  • the heat exchanger wall is a good heat-conducting wall, with the interface of the heat exchanger wall representing the surface of the heat exchanger in the direction of the gap.
  • thermal contact is established between individual elements of the medium line, thus increasing the cooling surface of the heat exchanger.
  • the interface is cooled by a cold medium that is passed through the medium line.
  • the medium line is first cooled and due to heat conduction, the surface of the medium line and also the heat exchanger wall and the interface become cold.
  • the medium line has the coldest point close to the medium inlet. The further the medium line extends towards the medium outlet, the warmer it becomes.
  • the heat load in the room can be caused, for example, by solar radiation or by the heat given off by people.
  • the infrared thermal radiation emitted by the heat load is absorbed by the interface and removed from the room by the cold medium.
  • the condensing cavity is provided adjacent to the medium line.
  • the condensing cavity is a small air cavity that is formed on the side facing away from the heat exchanger wall with respect to the surface element.
  • the heat exchanger wall has at least one opening, so that the intermediate space is communicatively connected to the condensing cavity.
  • the air moisture that accumulates in the gap passes through the opening from the gap into the condensation cavity and condenses there on the cold medium line.
  • the condensing liquid is transported to the outside due to the capillary effect of the capillary material and can dry there in the air.
  • the pores of the capillary material are so fine that only a minimal entry of moisture occurs through diffusion into the capillary material both inside the heat exchanger panel and outside. This means that almost no water vapor can penetrate from outside and there is almost no flow of gas from outside towards the condensation cavity. If the pores are filled with water in the case of condensation, then they are impermeable to vapor diffusion. Since the condensed water is distilled water, there is no risk of clogging of the pores. In addition, no liquid moves through the capillary material from the outside to the condensation cavity, since the water vapor pressure and material moisture of the capillary material is greater inside the condensation cavity than on the outer surface.
  • the air humidity that occurs in the gap is not evenly distributed throughout the entire gap, but rather condenses primarily at the coldest point of the medium pipe. Since the moisture is removed from the air at this point, more air with higher humidity moves in this direction and the moisture condenses again.
  • the medium line is thus shielded from a large part of the heat radiation by the heat exchanger wall and remains in a cool state.
  • the medium line can be formed from one or more straight line sections or from a meandering line.
  • the heat exchanger has a meandering medium line.
  • the medium line is preferably designed in such a way that it has a supply line and a discharge line with a large cross section, which are arranged approximately parallel to one another and connecting lines with a smaller cross section are arranged between them.
  • the connecting lines run approximately parallel to each other and connect the supply line and the discharge line.
  • These connecting lines can be capillary tubes and such a line system with capillary tubes is also referred to as a capillary tube mat, especially if the lines are made of plastic.
  • the heat exchanger panel can include a ceiling or wall panel in which the medium line is embedded.
  • the medium line is preferably integrated into the ceiling or wall panel in such a way that the material of the ceiling or wall panel fills the spaces between the individual elements of the medium line.
  • the space between the interface and the surface element can be bordered laterally by edge elements.
  • the ceiling or wall panel and the edge elements can be made of a substantially diffusion-tight material. With this configuration, the heat input into the medium line and the moisture input into the space between the interface and the surface element are kept as low as possible.
  • the interface of the heat exchanger wall is particularly relevant for temperature control of the room. This interface can be smooth or rough in order to influence its absorption or reflection behavior.
  • the heat exchanger wall can, for example, be a layer made of metal or contain or consist of a metallic alloy.
  • the performance of the heat exchanger panel according to the invention can be increased through a high thermal conductivity and/or high heat capacity of the interface and high absorption in the radiation range of the temperature radiation of 2 to 20 pm wavelength.
  • the response behavior of the heat exchanger panel can be specifically influenced by a low or high heat capacity of the interface, or by additionally introduced or attached latent heat storage materials (PCM).
  • PCM latent heat storage materials
  • the area in which the condensation cavity is formed adjacent to the medium inlet can comprise at least 10% or at least 20% or at least 30% of a length of the medium line.
  • the condensing cavity in contrast to the surface of the heat exchanger wall, does not receive any heat radiation, it is fundamentally cooler than the heat exchanger wall.
  • a plurality of openings can be formed in the heat exchanger wall, the openings having a minimum clear width of at least 0.2 mm or at least 0.3 mm or at least 0.4 mm and/or a maximum clear width of 1.5 mm or have a maximum of 1.4 mm or a maximum of 1.3 mm.
  • the openings can also be designed as longitudinal or elongated slots or combinations of slots and round openings.
  • the heat exchanger wall can also be made of a vapor-permeable material in the area of the condensing cavity.
  • the heat exchanger wall has openings in the form of perforations.
  • the hole size of the perforation is chosen so that water vapor can flow through, but not liquid water. This prevents water from dripping from the condensation cavity towards the surface element and accumulating there. This would lead to permanent damage to the heat exchanger panel.
  • the surface element can show a transmission of more than about 50% or of more than about 70% or of more than about 90%, at least in a partial area .
  • the surface element decouples the heat exchange at the interface of the heat exchanger wall by means of heat radiation and heat conduction. Consequently, the interface can be cooled to a temperature below the dew point of the moisture in the room air. Heat can be effectively removed from the room through thermal radiation.
  • the surface element can, for example, contain or consist of a polymer.
  • the wavelength range mentioned contains a large part of the energy of the thermal radiation of a black body at around 300 K. If the heat exchanger panel according to the invention is in one If the device is to be used in warmer climates, this wavelength range may be shifted. Shorter wavelengths can also occur if the room has special heat sources, such as electrical or electronic devices. A transmission of about 50% to about 90% in at least a portion of the wavelength range mentioned ensures that a sufficient proportion of the thermal radiation reaches the interface of the heat exchanger wall and can in this way be transported out of the room.
  • the transparency and the associated low degree of absorption and emissivity of the surface element in the above-mentioned wavelength range of the material ensure that the surface element releases little heat energy to the interface and therefore does not cool down and therefore does not fall below the dew point of the moisture in the room air.
  • the surface element can be designed to be at least partially reflective and/or absorbent in the visible spectral range, so that a visually appealing design is made possible.
  • a trough can be provided which completely or approximately completely encloses the ceiling or wall panel on the side facing the ceiling or wall, and/or which completely or approximately completely encloses the medium line and the condensing cavity on the side facing the ceiling or wall completely encloses.
  • the trough can be made of a diffusion-tight material, preferably of a metal such as aluminum.
  • the trough thus insulates the ceiling or wall panel and subsequently also the condensation cavity from the ceiling or wall-side environment, which is normally formed by an insulating material that is not completely diffusion-tight. If the trough only encloses the medium line and the condensing cavity, then in particular the medium line and the condensing cavity are insulated from the environment.
  • a heat-insulating and/or sound-absorbing layer and/or a layer that is diffusion-tight to water vapor can be provided.
  • the heat-insulating layer can, for example, reduce energy losses from a room to the outside or into volumes and areas that do not need to be heated.
  • the sound-absorbing layer reduces the sound level in the room by absorbing sound waves and the resulting conversion into heat energy. This improves, among other things, speech intelligibility in rooms.
  • the sound-absorbing layer is, for example, an acoustic foam and is preferably made of the same material as the diffusion-tight thermal insulation material.
  • the acoustic foam has more open pores compared to the thermal insulation material surface.
  • the layer which is diffusion-tight to water vapor, prevents moisture from entering the ceiling and/or the wall of the room or on the surface of the heat exchanger.
  • Electronic components such as sensors, semiconductors, LEDs and/or other active or passive components or thermal or hygroscopic storage materials, can be arranged between the heat exchanger wall and the surface element and/or on the side of the surface element facing the room.
  • the components can also be electrothermal components, such as Peltier elements.
  • a PCM material can also be introduced for thermal buffering.
  • a heat exchanger panel according to the invention can not only serve to control the temperature of a room, but at the same time contribute to the visual design and workplace lighting of the room with lighting elements.

  • the heat exchanger wall 11 additionally forms the capillary material 18 and leads to the outer surface 19 of the ceiling or wall panel 4.
  • the capillary channels can be incorporated into the surface of the heat exchanger wall 11, for example by means of a laser.
  • the capillary channels have a circular surface of at least 0.1 mm 2 or at least 0.3 mm 2 or at least 0.5 mm 2 and/or a circular surface of a maximum of 1 mm 2 or a maximum of 0.75 mm 2 or a maximum of 0 .5 mm 2 on.
  • Heat radiation emanating from a heat load in room 2 transmits at least partially through the surface element 13. From there, after crossing the intermediate space 16, it reaches the interface 12 of the heat exchanger wall 11 and is absorbed there. The heat is absorbed and dissipated by the heat exchange medium that flows through the medium line 5 via heat conduction.
  • a sound-absorbing layer 20 is introduced into the material of the ceiling or wall panel 4.
  • the sound-absorbing layer 20 is preferably an acoustic foam and is preferably made of the same material as the diffusion-tight thermal insulation material of the ceiling or wall panel 4.
  • the acoustic foam has a more open-pored surface compared to the thermal insulation material.
  • the sound absorbing layer 20 reduces the sound level and the reverberation time in room 2.
  • lighting elements 21 are provided on the side of the surface element 14 facing away from the room 2.
  • the lighting elements 21 can be provided both on the side of the surface element 14 facing the room 2 and on the side of the surface element 14 facing away from the room 2.
  • the lighting elements 21 are, for example, LEDs that are attached to the surface element 14 at a distance from one another.
  • a ceiling or wall panel 4 can not only serve to control the temperature of the room 2, but at the same time contribute to the optical and technical design of the room 2 with lighting elements 21.
  • the lighting elements 21 are preferably connected to a control device 22.
  • the control device 22 can be controlled using a remote control. For example, the lighting elements 21 can be switched on and off individually or the brightness of the lighting elements 21 can be individually adjusted.
  • further electronic components such as sensors, semiconductors, LEDs and/or other active or passive components or thermal storage materials, can also be arranged on the surface element 14.
  • Both the lighting elements 21 and/or the other electronic components are arranged in such a way that a portion of thermal radiation that is necessary and sufficiently large for the invention can pass through the surface element 14 and reach the interface 12.
  • the lighting elements 21 and/or the further electronic components can also be designed in such a way that, like the surface element 14, they are at least partially permeable to thermal radiation and almost impermeable to air.
  • a cool heat exchanger medium is passed through the medium line 5 of the heat exchanger 3 of the heat exchanger panel 1 in order to cool it.
  • Moisture located in the intermediate space 16 of the heat exchanger panel 1 condenses in the condensing cavity 13 adjacent to the medium line 5.
  • the moisture accumulated in the condensing cavity 13 is absorbed by the section of the capillary material 18 arranged in the condensing cavity 13.
  • the moisture in the capillary material 18 is conducted and discharged to an outer surface 19 of the heat exchanger panel 1. Here the moisture is released into the environment.

Abstract

L'invention concerne un panneau d'échangeur de chaleur comprenant un échangeur de chaleur. L'échangeur de chaleur a une conduite de milieu pour conduire un milieu d'échangeur de chaleur d'une entrée de milieu à une sortie de milieu et une paroi d'échangeur de chaleur thermiquement conductrice qui est reliée à la conduite de milieu, et la paroi d'échangeur de chaleur forme une surface de limite faisant face à un espace, la surface de limite pouvant être amenée à une température qui est inférieure à une charge de chaleur. Entre la surface limite et l'espace, au moins un élément plat est disposé, lequel est au moins partiellement perméable au rayonnement thermique et est presque imperméable à l'air, de telle sorte qu'un espace intermédiaire presque étanche à l'air est formé entre la surface limite et l'élément plat. L'échangeur de chaleur est caractérisé en ce que, dans la région adjacente à l'entrée de milieu, une cavité de condensation est formée adjacente à la conduite de milieu et sur le côté opposé à la paroi d'échangeur de chaleur par rapport à l'élément plat, et la paroi d'échangeur de chaleur a au moins une ouverture, de telle sorte que l'espace intermédiaire est relié de manière communicante à la cavité de condensation. Dans la cavité de condensation, une substance capillaire est disposée ou au moins un élément capillaire actif est disposé, lequel est conduit vers une surface externe du panneau d'échangeur de chaleur, de telle sorte que la condensation de liquide dans la cavité de condensation est transportée vers l'extérieur en conséquence de l'effet capillaire de la substance capillaire ou de l'élément capillaire actif, et peut y sécher à nouveau.
