Definitions

  • the present invention relates to a method for conditioning, especially dehydration, of a gas, such as air.
  • the invention also relates to a device carrying out the method.
  • This object is attained by combining, according to the invention, a cooling dehydrator with a regenerative exchanger apparatus in such a manner that the air which shall be dehydrated firstly is conducted over the evaporator of the cooling circuit before it reaches the treating zone of the regenerative exchanger apparatus, and that the effect of the cooling circuit is adjusted so as to avoid a formation of ice on the evaporator.
  • a cooling dehydrator with a regenerative exchanger apparatus in such a manner that the air which shall be dehydrated firstly is conducted over the evaporator of the cooling circuit before it reaches the treating zone of the regenerative exchanger apparatus, and that the effect of the cooling circuit is adjusted so as to avoid a formation of ice on the evaporator.
  • Figure 1 shows a diagrammatic view of a plant according to the invention of carrying out the novel method.
  • Figure 2 shows a view similar to Figure 1 of a changed embodiment of the plant.
  • the gas which is to be treated according to the invention is air to be dehydrated and that the regenerating gas also is air, even if the invention is not limited thereto.
  • outdoor air denoted with the arrow 10 is blown by means of a fan 12 into a room 14 after that the air has been dehydrated by means of an evaporator unit 16 and a regenerative exchanger apparatus 18.
  • the evaporator unit 16 which will be described nearer more below, achieves by cooling of the air a first dehydration of the air, from which the main part of the water content is removed, whereas the regenerative exchanger apparatus dries the air finally to the desired state.
  • the exchanger apparatus is constituted by a rotor containing a moisture absorbing drying mass of a material which in itself is absorbing and/or impregnated with a hygroscopic substance.
  • the moisture exchanger rotor 18 is subdivided into a drying zone through which the outdoor air 10 streams, as mentioned above, and a regenerating zone, within which the regenerating air which is indicated at the arrow 20, is brought to flow by means of a fan 22.
  • the regenerating air is taken from the room 14, as in the shown embodiment, even if, of course, other possibilites are conceivable.
  • the regenerating air 20 is supplied upon preheating to the regenerating zone of the rotor 18, in which the moisture taken up by the rotor is removed.
  • the proportion between the drying zone and the regenerating zone is 1:1, i.e. each of the zones covers approximately one half of the rotor surface.
  • a cooling dehydrator in the shape of a heat pump circuit, over the evaporator 16 of which the outdoor air passes ahead of 'the exchanger 18.
  • a preheating also of the regenerating air is effected prior to the entrance into the regenerating zone of the exchanger 18 by means of the condenser 24 of the heat pump circuit.
  • the circuit comprises also a compressor 26 and a conduit system 28 which connects the components contained therein.
  • the heat pump circuit or system contains also other elements necessary of the operation thereof such as throttle valve 30 and other details of the kind usual in this technique for the opeartion.
  • the described plant works as follows: The air entering at 10 is cooled and dehydrated on one hand in the evaporator 16, on the other in the moisture exchanger'18, as has been described above, whereafter it is supplied to the room 14. At very warm weather conditions, for example at 40°C, and with the highest moisture in the outdoor air, the plant works with its full capacity, i.e. the heat pump circuit is in opearation with full capacity.
  • the arrangement is such, that the cooling dehydrator or evaporator 16 is operated with the highest possible capacity without any formation of ice taking place.
  • the cooling circuit is controlled as to its capacity in such a manner that when a risk of formation of ice on the evaporator 16 is present, a portion of the refrigerant gas coming from the compressor 26 - instead of being conducted to the condenser 24 and there becoming condensed - is conducted via a branch conduit 44 to a point in the heat pump circuit 28 behind the throttle valve 30 in the evaporator 16 and there is mixed with the vaporized refrigerant gas.
  • the refrigerating capacity in the evaporator 16 is reduced in relation to the temperature of the entering outdoor air.
  • a further heat pump circuit which comprises a compressor 32, a condenser 34, a throttle valve 36 and a conduit system 38, which connects the mentioned units with an evaporator circuit 16a.
  • the two heat pump circuits are separated from one another and affect also two separate evaporator circuits 16, 16a, as is shown diagrammatically in Figure 1.
  • the evaporators may be built to form a unit by means of common flanges of the so-called inter-twin-type.
  • the evaporator or that circuit in the combined evaporator 16, 16a which belongs to the heat pump circuit with the highest capacity or effect and which therewith has the largest cooling capacity, shall be located last, viewed in the direction of flow of the outdoor air.
  • the condenser 24 in this heat pump circuit with the highest capacity, which condenser 24 has low condenser capacity and the largest heat supply be situated first in the direction of flow of .the regenerating air towards the regenerating zone of the exchanger apparatus 18, as is shown in Figure 1 of the drawing.
  • the evaporator can suitably, as is shown at 116a, be transferred to a position behind the rotor viewed in the direction of flow for the outdoor air, in which position the air is dryer and warmer, because it has passed both the cooling circuit to the evaporator 116 and the rotor 18.
  • the evaporator 116a may be transferred to the position 116b indicated by dashed lines, i.e. behind the rotor 18 in the channel for the outlet air. In these cases the evaporators 116a or 116b, respectively, will through the condenser 34 supply heat to the regenerating air in the regenerating air stream 20.
