Definitions

  • the invention relates to a humidifier with a water reservoir and arranged in the water tank heat exchanger, which is connected on the secondary side to the water reservoir.
  • humidifiers which are designed as evaporators, evaporators or atomizers.
  • evaporators evaporators
  • atomizers evaporators
  • evaporators evaporators
  • atomizers evaporators, atomizers
  • any bacteria in the water are killed by heating the water.
  • fuel firing systems are used, which, however, require a relatively high design effort.
  • electrical heating elements are used, but in comparison with fuel firing due to the expensive energy carrier are economically unprofitable.
  • the invention is therefore based on the object, a humidifier in such a way that the associated with a fuel firing design effort and at the same time an economically favorable operation can be ensured.
  • the invention solves the problem by the fact that the heat exchanger is integrated on the primary side as a capacitor in the refrigerant circuit of a heat pump and the secondary side connected to a steam distribution line.
  • existing heat sources such as waste heat or exhaust air of industrial plants
  • the refrigerant of the heat pump is heated via the evaporator in heat exchange with the heat source and compressed by means of a compressor with additional heating, before the heated refrigerant absorbed heat energy via the heat exchanger surfaces of a heat exchanger to the water to be evaporated.
  • the primary side of the heat exchanger forms the condenser of the refrigerant circuit of the heat pump, while the secondary side is acted upon by the water from the water reservoir.
  • the heat pump be designed in several stages.
  • a plurality of refrigerant circuits with increasing temperature level can be connected in series, wherein the condenser of the one refrigerant circuit serves as a heat source for the evaporator of the subsequent refrigerant circuit.
  • heat transfer in the heat exchanger results in particularly advantageous conditions when the heat exchanger is designed as a plate heat exchanger, coaxial heat exchanger or tube bundle heat exchanger.
  • the water reservoir can have a level control, with fresh water being supplied as a function of the water level in the water reservoir.
  • an evaporator 1 takes a circulated refrigerant thermal energy of a heat source, not shown, for example, the environment, and is supplied to a compressor 2, which is the refrigerant compressed to a higher pressure level and additionally heated.
  • a heat exchanger 3 condenser condenses the refrigerant with heat release.
  • the heat exchanger 3 Since the heat exchanger 3 is arranged within a water reservoir 4, water can flow from the water reservoir 4 into the secondary-side inlet 5 of the heat exchanger 3 and is heated by the heat energy of the refrigerant discharged via the heat exchanger surfaces. If a sufficient heat input is achieved, the water evaporates within the heat exchanger 3 and can be supplied to the humidified air flow via a secondary discharge of the heat exchanger 3 connected steam distribution line 6 by means not shown in detail, such as blowers or steam lances. At the same time, water from the water reservoir 4 flows into the inlet 5 in accordance with the quantity of steam taken off and is likewise heated.
  • the condensed refrigerant is finally expanded via a throttle 7 and fed to the evaporator 1 in a conventional manner, in turn there to absorb the thermal energy of the heat source.
  • a heat exchanger 8 is arranged, which acts on the primary side as a condenser for the refrigerant circuit K 1 and on the secondary side as an evaporator for the refrigerant circuit K 2 .
  • the water reservoir 4 has a filling valve 9 for fresh water, which is controlled via a control device 10 as a function of the measured value of a water tank 4 associated level sensor 11.
  • a drain valve 12 is provided for emptying the water reservoir and for rapidly reducing the vapor pressure.
