Definitions

  • the present invention relates to a device for heating air and a liquid.
  • the object underlying the invention is to propose a device for heating air and a liquid which represents an alternative to the prior art.
  • the invention solves the problem with a device for heating air and a liquid, with an air inlet, an air outlet, an air interaction area, an air delivery device, a liquid inlet, a liquid outlet, a liquid interaction area, a liquid delivery device, an energy unit, a heat exchanger, and a control unit , with air to be heated entering the device via the air inlet, with heated air leaving the device via the air outlet, with liquid to be heated entering the device via the liquid inlet, with heated liquid leaving the device via the liquid outlet, with the energy unit thermal energy generated, wherein the heat exchanger transfers the thermal energy generated by the energy unit to the air in the air interaction area and to the liquid in the liquid interaction area, the air conveying device conveying the air into the air interaction area, the liquid conveying device conveying the liquid into the liquid interaction area, wherein the control unit controls the air delivery device and the liquid delivery device as to whether the device only heats air in an air mode or liquid in another mode.
  • CONFIRMATION COPY Depending on the mode, air or liquid is conveyed by the two associated conveying devices to the corresponding interaction areas, in which they receive thermal energy from the heat exchanger.
  • the liquid delivery device is, for example, a pump and the air delivery device is a blower.
  • the control unit switches between the modes.
  • the air is preferably room air in a room and the liquid is, for example, process water.
  • control unit is designed in such a way that it controls the air delivery device and the liquid delivery device to determine whether the device only heats air in an air mode or only liquid in a liquid mode.
  • this configuration there are thus two modes in which only air or only the liquid is heated.
  • the liquid mode the small amount of room air, which may be heated by providing the thermal energy, is ignored as a by-product.
  • a further embodiment provides that the control unit controls the air delivery device and the liquid delivery device to determine whether the device heats only air in an air mode, only liquid in a liquid mode or air and liquid in a mixed mode.
  • the control unit controls the air delivery device and the liquid delivery device to determine whether the device heats only air in an air mode, only liquid in a liquid mode or air and liquid in a mixed mode.
  • One configuration consists in the control unit controlling the liquid delivery device before the air mode in such a way that the liquid interaction area is essentially free of the liquid.
  • the liquid is removed from the interaction area of the liquid before the air mode and in particular is not refilled, so that no liquid and thus only air is heated in the air mode.
  • One embodiment provides that when changing from the air mode to the other mode (e.g. liquid mode or mixed mode, if implemented), the control unit controls the liquid delivery device in such a way that in the Liquid interaction area, the liquid only arrives when a critical temperature of the heat exchanger is below a predetermined starting value.
  • the liquid is only heated when a certain temperature of the heat exchanger is sufficiently low and in particular lower than a predeterminable starting value. This avoids unwanted noise or pressure shocks, for example.
  • the start value is the temperature value at which the liquid mode or the mixed mode (as examples for the other operating mode, in which only or also liquid is heated) is started.
  • the critical temperature relates in particular to an area of the heat exchanger whose temperature affects the liquid.
  • One configuration consists in that the device also has a temperature sensor, that the temperature sensor detects a temperature of the heat exchanger, and that the control unit evaluates the temperature detected by the temperature sensor with regard to the critical temperature of the heat exchanger.
  • the control unit uses the measurement signals from a temperature sensor to determine whether the heat exchanger has cooled down sufficiently.
  • An alternative or supplementary embodiment provides that when changing from the air mode to the other mode (e.g. liquid mode or mixed mode), the control unit controls the liquid delivery device in such a way that the liquid only enters the liquid interaction area when after an end of the air mode, at least one predefinable cooling period has elapsed.
  • the cooling time is the time that the heat exchanger needs to cool down from a temperature of the air mode to a temperature below the start value and can be determined from the cooling behavior of the heat exchanger.
  • the energy unit generates thermal energy by burning a fuel/air mixture and/or by converting electrical energy.
  • the thermal energy is generated by burning a fuel, e.g. B. combustible gas or diesel fuel converted into the gaseous state, or generated by the conversion of electrical energy.

  • FIG. 1 schematically shows the structure of a device for heating air and a liquid.
  • the air enters the device through the air inlet 1 and leaves it warmed up through the air outlet 2.
  • the liquid for example water, enters the device via the liquid inlet 5 and leaves it warmed up via the liquid outlet 6.
  • a liquid container through which the liquid passes from the liquid inlet 5 to the liquid outlet 6.
  • the thermal energy for heating is generated by the energy unit 9 in the variant shown by burning a fuel-air mixture.
  • the heat exchanger 10 transfers this thermal energy to the air, to the liquid or both to the air and to the liquid, depending on the mode.
  • there are two interaction areas for transferring the thermal energy there are two interaction areas for transferring the thermal energy: an air interaction area 3 and a liquid interaction area 7.
  • the air or liquid is conveyed by the two conveying devices 4, 8 through the respective associated interaction area 3, 7.
  • a temperature sensor 12 is provided for this purpose, which detects temperature values of the heat exchanger 10 .
  • the measurement signals are evaluated by the control unit 11 with regard to a temperature that is critical for the liquid. Only when the heat exchanger 10 has cooled down sufficiently does the liquid delivery device 4 transport the liquid into the liquid interaction area 3 when changing from one air mode to another mode.
