Abstract: FIELD: electronics, electrophysical treatment of gaseous media, mainly air in residential, industrial and other rooms. SUBSTANCE: bioaeroionizer comprises ionizing electrode system, voltage generating system and system for voltage supply to ionizing electrodes. Structural components of plants, such as pointed tips, lanates and/or sharp edges are used as ionizing electrodes. Number of ionizing electrodes and their geometric dimensions are selected so that total added-up volume v1 of their effective ionization areas would be evaluated in relation to total volume v2 defined by system of tangential planes drawn to remotemost points of ionizing electrode system within range 1.001<=(v1+v2)/ v2 <= 2, while volume v2, as related to volume v3 defined by system of tangential planes drawn to remotemost points of plants, is selected to be comprised within range 1.0001 <=(v2+v3)/v3 <=2. Equivalent resistances R1 of plant components, through which feed voltages are applied to ionizing electrodes, are selected so as to be comprised within range 1 <= (R1 + R2) / R2 < = 100000000. Proposed method employs, as an aeroionizer of biological objects, mainly plants and/or the latter are used as an oxygen source for aeroionization. Method comprises the following steps: First required feed voltages are generated and applied to ionizing electrodes. Gaseous medium is exposed to effects of ion discharges, whereupon electric charges are redistributed within gaseous medium. Feed voltages are generated in form of negative-polariry pulses having arbitrary, mainly rectangular shape. Peak values of instantaneous voltage amplitudes, respectively A1 and A2, in every two, successively generated neighboring pulses are within range 1<=(A1 + A2) / A2 <= 2, while ratio of minimum t1 and maximum t2 pulse durations is selected to be comprised within range 1 <= (t1 + t2)/ t2 <= 2. Total volume v4 of oxygen released by plant during operation time of bioaeroionizer and of oxygen contained in surrounding air is related to volume v5 of air to be saturated with negative ions and this ratio must be comprised within range 1.1<=(v4+v5)/v5<=2. Total current value i1 passed through plant components is related to its maximum permissible value 12 and must be comprised within range 1<=(i1+i2)/i2<=2, surface current value i3 must be comprised within range 1<=(i3+i2)/i2<=2, while current leakage value i4 must be kept within range 1<=(i4+i2)/i2<=1.5. If this condition is observed, ratio of these current is kept within range 1.00000001<= (i1+i2+i3+i4)/i2<= 5. With this approach, ratio of minimum q1 and maximum q2 negative ion charge densities in each microvolume of gaseous medium being treated is comprised within range 1.1<=q1+q2)/ q2<=2. Finally, peak value of short-circuit current i5 is forcibly limited from any point of medium being treated and/or from any point of surfaces having electric potential in relation to current i2 and is kept within range 1<=(i1+i2)/ i2<=100. EFFECT: broader functional potentialities of biological objects, mainly plants, higher efficiency of saturation of gaseous media with negative oxygen ions, in particular due to additional oxygen liberated by plants. 3 cl
