Description

ARRANGEMENT FOR IMPROVE OP ATMOSPHERIC CONDITIONS CLOSED PARTICULARLY IN BUILDINGS AND BY MEANS OP ELECTRODES CONNECTED TO A HIGH DC VOLTAGE The invention relates to an arrangement for the improvement of atmospheric in cular in closed in which an electrostatic is created electrodes provided in said which electrodes are connected to terminals of a source of direct current of high In known installations of this kind usually two electrodes are for example one connected to a positive terminal of the source of direct current situated below the ceiling of the space and insulated relative to said and the other being connected to a negative terminal situated within the It is also possible to provide only one electrode in the ceiling connected to the positive while the negative terminal is so that the floor of the space itself constitutes the second It has also been proposed to provide an electrically insulated electrode in the region of the floor and to connect the same to the negative terminal of the current and to earth the positive terminal the walls and the ceiling of the space thus constituting the All installations of the kind are for the purpose of creating a voltage drop in the electrostatic which corresponds approximately to the temperature in open air on a fine day and to control the air condition in buildings in particular in modern constructions of concrete such as and dust such arrangements of electrodes an advantage in that it enables collection of dust in a much simpler manner than by the usual which latter require the provision of ventilators and collecting A ine in open air is characterized the following Relative humidity about temperature about atmospheric pressure relatively dust contents of air very concentration of small ions 200 to centration of large ions several 1000 voltage 2 drop 100 to 200 vertical current about The following of aforesaid features can be selectively controlled by means of a conventional conditioning Relative humidity ature and dust By an arrangement of electrodes of known kind the voltage drop and the vertical current can also be as well as the dust to a quite important up to the present the concentration of small and large could not be nor could control of atmospheric pressure be carried out except in particular because of the high expense It has been in air conditioning plants in which an electrostatic of high DC voltage is the result is not fully since in a closed space the ions in the atmosphere are said ions being collected according to their polarity by the corresponding rodes thereby impairing the voltage drop and the vertical This disadvantage of the known electrode may be eliminated according to the by in the region of at least one an the electrode and the for example such as metal strips impregnated with Tritium or the The emits with a maximum energy of corresponding to a maximum range of about 7 in air at atmospheric The the air so that in this manner on each metal strip positive and negative small ions are created about equal ing to the the respectively the carriers may be connected selectively to the terminal of the DC source which is coordinated to the for an electrically insulated cover may be provided on the side of the electrode which faces the space respectively on the lower side of a said cover having slits in vertical direction relative the grooves being provided in the side walls of said slits in which the emitting respectively its are The situated near the top part of the may be pointed to a lighting to a standard and the material may be mounted in particular when the electrode is situated at a relatively great distance from the space ceiling preferably below and above said The subject of the invention is shown schematically in the in which vertical section through a closed a ceiling and floor a metal strip impregnated with tritium being mounted in the region of the oeiling Z is a standard lamp with an the lighting for example a fluorescent being provided with an impregnated metal strip mounted below and above said In the drawings below oeiling 1 of a space which on all its an electrically insulated metallic electrode of any desired is arranged in while on floor of the space an electrode over which a floor cover may be laid in usual The DC source o high voltage of any is designated by The positive terminal the source is connected to the coiling electrode and its negative terminal to the floo electrode The negative is the of which the walls of the space is electrically the floor electrode 5 may be because the floor itself may serve as a counter for example as the negative In this speci ication and in the claims the term electrode is not limited to the usual sense of the but includes as well Other terminals which perform the same as ceilings or irrespective of whether they are of conductive or underside of ceiling electrode 3 is provided with an electrically insulated cover 8 as shown in the has channele 9 directed vertically relative electrode The side of said channels 9 are provided with grooves or simila in which metal strips 12 are said metal strips being impregnated with tritium example with an activity of 5 which emits As the of Tritium amounts to about the of Tritium ion source is about 20 years corresponding to an activity drop of of the starting As shown in the metal strips can be connected to the ing terminals of the DC source 7 which is connected to the electrode When a positive voltage of about 500 is connected to the ceiling electrode 3 most of the negative ions of the positive and negative ions created by the metal strips impregnated with Tritium are retained on the positive ceiling electrode so that most of the positive ions enter space When metal strips are connected to the same terminal to which ceiling electrode 3 in principle all created negative ions are If it is desired to emit negative ions into the it is possible to switch over the so that the negative terminal of voltage source 7 is connected to the ceiling electrode while the positive terminal is connected to the floor respectively the positive ions created by metal strips are retained in the region of the while the negative ions enter the space In the according to its height and the chosen a vertical voltage drop of 100 to 200 is corresponding to the conditions in open on a fine the air of the space is enriched homogeneously with positive or negative The voltage drop and the artificial ionization of the air create an ion current for example from the to the floor This that the disordered movement of the natural open is then replaced by a vertically directed moveaient of the naturally and artificially created The artificially created are primarily small These have a tendency to be collected on condensation dust or humidity particles and in this to large These large ions are also transported in electric to th or floor electrode respectively and are thus separated from the air of the creating a cleaning effect in the same way as in open It is of course possible under certain conditions to omit a special ceiling as alread mentioned and provide only a floor which is electrically insulated relative the When said floor electrode connected to the negative terminal of the voltage source the space ceiling if constructed of an electrically suitable the positive This a possibility of arranging the metal strips electrically insulated relative the space ceiling or also all connected to space 2 shows a transportable embodiment of the invention form of standard The latter fo tubes and a or electrode which can be connected ively to the positive or negative terminal of a As shown in an Insulating cover may be provided below and above electrode which cover may be ed similar to cover 8 of electrode 3 shown in metal strips mounted also above electrode may be if the lamp is open in upward direction as it frequently is and the distance of electrode 3 from the ceiling of the space is relatively to provide for ions to enter the space situated immediately above the Many modifications are of course possible in the arrangement of the electrode and the impregnated metal which need not be Also in the case of use of a standard lamp or the like the impregnated metal strips may be connected ively to the coordinated electrode as has been described with to insufficientOCRQuality
