Definitions

  • the invention relates to a plate heat exchanger for applying a supply air flow with cooling energy, which is in the plate heat exchanger a humidified before flowing through the plate heat exchanger cooling air flow and transferable to the supply air, with politicianstaucherplatten on one side of Zu Kunststoff- and on the other side of the cooling air flow can be contacted and their contacted by the cooling air flow sides are provided with a hydrophilic lacquer coating, which is wetted with moisture from the cooling air flow.
  • the invention has the object of providing a plate heat exchanger of the type described in such a way that it, without impurities or contamination occur on the supply air flow exposed side of its heat exchanger plates can provide a quasi-constant temperature level.
  • the hydrophilic lacquer coating is formed on the side contacted by the cooling air flow side of the heat exchanger plate so that in its moisture from the cooling air flow can be stored. Moisture can be absorbed by this storage medium, which is not in operation in those periods in which the temporally clocked spraying device, which applies moisture to the cooling air flow upstream or upstream of the plate heat exchanger. As a result of this release of moisture from the storage medium to the free surface of the hydrophilic lacquer coating, a largely constant layer thickness of the wetting on this free surface can be ensured, which ultimately results in no temperature fluctuations occurring on the side of the heat exchanger plates of the plate heat exchanger exposed to the supply air flow.
  • zeolite As an inorganic storage medium zeolite has proven particularly advantageous, which can be provided in a simple manner in the hydrophilic lacquer coating.
  • zeolite In particular in nanocrystalline form, zeolite has proven advantageous, preferably a particle diameter ⁇ 1000 nm (nanometers) and in particular between 100 nm and 500 nm should be maintained.
  • Such zeolite materials can in an excellent manner in cooperation with the hydrophilic lacquer coating store moisture within the coating itself, this moisture can be delivered to the free surface of the paint coating in downtime of the arranged in the cooling air flow upstream or in front of the plate heat exchanger spraying.
  • the cooling air flow flowing through the plate heat exchanger can be an exhaust air flow or an outside air flow or a mixture of exhaust air flow and outside air flow, the cooling air flow designed in this way preferably being humidified adiabatically.
  • the heat exchanger plates of the plate heat exchanger may be formed of a metallic material or plastic.
  • a plate heat exchanger according to the invention has a multiplicity of heat exchanger plates 1 arranged at a distance from each other in a manner known per se, of which a section is shown in the single figure.
  • Each of these plurality of heat exchanger plates 1 has a side 2, which is contacted by a supply air stream 3, and another or other side 4, which is contacted by a cooling air flow 5.
  • the plate heat exchanger having the plurality of heat exchanger plates 1 serves for cooling energy from the cooling air flow 5 withdraw and hereby act on the supply air stream 3.
  • the cooling air flow 5 is for this purpose upstream, i. in front of the plate heat exchanger, adiabatically charged with moisture. Serves for this purpose a Bedüsungsvorraum not shown in the figure, which humidifies the cooling air flow 5 upstream of the heat exchanger.
  • a Bedüsungsvorraum not shown in the figure, which humidifies the cooling air flow 5 upstream of the heat exchanger.
  • an exhaust air flow or an outside air flow can be used as the cooling air flow 5.
  • the moistened cooling air flow 5 carries with it the moisture introduced into the plate heat exchanger or its heat exchanger plates 1.
  • Each heat exchanger plate 1 of the plate heat exchanger is provided at its other, the cooling air flow 5 facing and contacted by this page 4 with a hydrophilic lacquer coating 6.
  • a hydrophilic lacquer coating 6 On the outside of the hydrophilic lacquer coating 6, the moisture contained in the cooling air flow 5 settles in the form of a moisture layer.
  • the hydrophilic lacquer coating is designed such that the wetting of their free surface is as uniform as possible, so that the other side 4 of the heat exchanger plate 1 is wetted over the entire surface and with the same thickness. This results in favorable transmission options for the cooling air flow side cooling energy to the supply air flow.
  • zeolite 7 is introduced into the hydrophilic lacquer coating as a storage medium. Moisture can be present in the zeolite 7 contained in the lacquer coating 6 be received and stored, which is discharged at a standstill of the upstream of the plate heat exchanger, the cooling air flow 5 acting jetting device gradually to the free surface of the paint coating 6, so that the layer thickness of the wetting layer remains substantially constant.
  • the zeolite 7 or storage medium used is preferably a nanocrystalline zeolite having a particle diameter between 100 and 500 nm (nanometers).
