Definitions

  • the invention relates to a method according to the preamble of claim 1, a device for performing this method, a heating system with such a device, and an air conditioning system with such a heating system.
  • the object of the present invention is therefore, in particular, to provide a method and a device for carrying out this method which do not have these disadvantages mentioned above, and complete combustion, i.e. to enable near-stoichiometric, and can still burn very small amounts of fuel per unit of time perfectly.
  • the air supplied to the atomizing area of the fuel atomizer is given a swirl before being mixed with the atomized fuel in such a way that the swirl axis is at least approximately equal to the atomizer main dust direction of the fuel atomizer coincides.
  • the invention further relates to a device for carrying out the method according to the invention.
  • the invention also relates to a heating system with a device according to one of claims 3 to 6, and an air conditioning system with such a heating system.
  • the device shown has a speed-controlled airflow generator 2 of example within the cylindrical housing 1 have 1.8 watts for generating an air flow 3, and a first flow guide 4 downstream of this air flow generator 2 for generating an at least approximately laminar air flow.
  • a commercially available air volume flow measuring device 6 Arranged in this laminar flow area 5 is a commercially available air volume flow measuring device 6 and, in the flow direction after this laminar flow area 5, a second flow guide 8 consisting of five guide vanes 7 (see in particular FIG. 3).
  • This diffuser 8 gives the flowing, precisely regulated air a swirl around the longitudinal axis 9 of the burner for intensive mixing of the metered air with extremely fine atomized heating oil supplied from the ultrasonic fuel atomizer 10.
  • the latter is fed completely pressure-free to the fuel atomizer 10 provided with a piezoelectric ultrasonic oscillator by means of a pump (not shown) via line 11 and the solenoid valve 12.
  • a computing unit 14 connected to the air volume flow measuring device 6 via a feed line 13 is connected to an air temperature sensor 15, an air pressure sensor 16 and a fuel flow measuring device 17, and immediately electronically calculates the parameters for a near-stoichiometric one from the parameters determined in this way Combustion required exact amount of air, and regulates, if necessary, the speed of the airflow generator 2 until the required amount of air is supplied exactly.
  • a flame tube 18 made of ceramic is arranged in the flow direction after the fuel atomizer 10, the adjoining combustion chamber can be lined with fireclay brick in a known manner.
  • the flame tube 18 is connected to the rest of the burner via thermal insulation 19.
  • the burner described above is connected to a boiler 21 and the latter is connected to a chimney 22 on the flue gas side.
  • the outlet of the latter is provided with a chimney hat 24 in order to influence the chimney draft as little as possible through the chimney outlet from outside air flows 23.
  • a chimney top is e.g. available under the name "Basten-Regulator” (registered trademark) from the company Inventina AG., CH-7302 Landquart (Switzerland).
  • Such a chimney cap minimizes the influence of different wind flows from the chimney outlet mouth on the natural draft in the chimney 22, so that the air pressure in the boiler 21 is practically unaffected by such chimney even with very gusty winds flows remains, and therefore represents an extremely important component in this burner concept.
  • the burner described can even be used to burn less than 300 grams of heating oil per hour and generates practically no noise.
  • the ignition device and the control of the piezoelectric ultrasonic vibrator are commercially available and are therefore not described in detail.
  • the total electrical energy consumption of this burner, including the measuring and control device, does not exceed the amount of 10 to 15 watts for a single-family house.
  • the exhaust side e.g. a CO and a CO2 sensor 25 and 26 are arranged at the outlet from this boiler for the near-stoichiometric combustion of solid fuels.
  • sensors 25 and 26 are electrically connected to the computing unit 14, the latter being programmed in such a way that when solid fuels are burned in the boiler combustion chamber, depending on the CO and CO2 actual values determined in this way on the exhaust gas side and predetermined corresponding target values, the speed and / or the direction of rotation of the air flow generator 2 is adjusted to achieve near-stoichiometric combustion with a small excess of air.
  • FIG. 5 also shows an air conditioning system provided with a heating system according to the invention for air conditioning living or office spaces.
  • the supply air to be treated is first controlled by a control element 29 corresponding to the volume of the computing unit 21 ' a connected to the cooling system 30 first heat exchanger 31 and then a second to the heating system 21 'connected to the second heat exchanger 32, the cooling system 30 and the heat supply to the second heat exchanger 32 regulating member 33 also depending on the determined indoor climate actual values and the predetermined target Values are controlled by the computing unit 21 '.
  • the first heat exchanger 31 can be used to cool the supply air 34 or, in combination with the second heat exchanger 32, to dehumidify the same.
  • the computing unit 14 is connected to an air volume flow measuring device 36 arranged in the supply air duct 35 and to a temperature and humidity sensor 37 and 38 for determining the corresponding actual values of the supply air 34.
  • a water ultrasonic atomizer 39 is also arranged in the supply air duct 35, which increases the moisture content of the air flowing through as a function of actual moisture values determined in the air duct and / or in the room 40 to be air-conditioned and supplied to the computing unit 14 and predefined target values if the latter is undershot .
  • a computer unit 14 which is also controlled Solenoid valve 42 arranged to regulate the water flow to the atomizer 39.
  • a water atomizer 39 provided with a piezoelectric ultrasound transmitter is extremely advantageous because it is possible with such an atomizer to introduce the required liquid to be supplied in the form of an extremely fine mist into the incoming air 34.
  • a flow guide device 43 consisting of guide vanes is provided in the outlet area of the ultrasonic atomizer 39, which gives the supply air 34 to be enriched with water and metered in this mixing area a strong swirl around the longitudinal flow axis 44.
  • the air conditioning system shown is not continuous as before, but only in the case of actual values that deviate greatly from the room climate setpoints in a corrective sense, which enables significant energy savings and an insufficient air change associated with the various disadvantages and dangers as well excessive ventilation with correspondingly high heating costs can be prevented.
