Description

FOR AIE CONDITIONING OF ENCLOSED SPACES GRAF I This invention relates to arrangements electrical air conditioning of enclosed spaces such as rooms and vehicles by setting up an electric field using at least one It is known to produce an electric more especially a constant direct current electric but also a direct current electric field with superimposed using two or using one electrode earthed bounding surfaces of said space serving as the electrodes being connected to a correspondingly high With the aid of this field numerous favourable particularly on human can be achieved or indirectly for example by influencing charge Amongst other things a reduction of aerosols d germs in the atmosphere of a room can be achieved by means a direct current It has already been observed that there are certain relationships between atmospheric humidity and field If the voltage producing the direct current field is kept the field strength generally falls rising atmospheric It has further been observed that the negative influence of higher atmospheric humidity on the being of humans can be partly eliminated by increasing voltage producing the direct current It has there ore also been proposed to control the direct current in dependence on atmospheric It is however interesting to note that the results achieved hitherto were not always Despite exactly identical adjustment of the electrical it was possible for example in some cases to detect a considerable reduction of aerosols and whereas in other cases results were not The problem underlying the invention is to provide an arrangement for electrical air conditioning by which reproducible and optimum results can be achieved to a substantially greater extent than This problem is solved according to the invent by an arrangement having in combination a per known device which influences atmospheric and a regulator which is so set that the atmospheric humidity in the electric field remains approximately With this arrangement the electric field produc g voltage can be kept constant at a value which is considered or can be varied in accordance with a predetermined The results which can be achieved in this manner are to a large extent since owing to the constant atmospheric humidity in the electric field an important which hitherto hindered reproducibility of the results of electric air is the regulation of atmospheric humidity is very much simpler than regulation of voltage in dependence on In order to obtain optimum a field strength recognised as favourable and an atmospheric humidity recognised as favourable can be combined with one another in such a manner that influencing of long duration is also In it is advisable that a temperature regulator should keep the temperature of the space approximately since thereby still further disturbing influences on the electric are The humidity regulator is advantageously set to a constant value of about relative This humidity range is one found by humans to be agreeable outside the electric and in addition has still further In special the regulator can naturally maintain a different constant value of humidity if des In a preferred embodiment of the invention the space bounding surfaces floor furniture serving as consist at least in part of a material possessing hygroscopic properties such that at the set atmospheric humidity they have on their surface a constant conductivity which is at least one power of ten better than that of If humidity is kept at a constant the surface conductivity of the space bounding surfaces also remains Charge carriers encountering these surfaces are therefore immediately so that they do not form a barrier layer in front of said surfaces distorting the In this connection it should be observed that this conductivity is achieved without a metal electrode or the like incorporated in the space bounding On the normal a large number of wall are Because of their lack of hygroscopic properties the use of plastics such as are obtained by sealing or by painting with plastics emulsion is general ly not In further development of the said device for influencing humidity may comprise an air humidifying device in the form of an atomiser or which is so constructed that the fine water particles carry an electric Not only is a determined humidity produced in this manner in the electric but also a higher ion concentration which has a very favourable influence on The production of ions may be effected for example by the Lenard by which very fine electric charge carriers are such as can for example also be detected in bathrooms when cold water is sprayed from the shower under high A humidity range from O to relative humidity is very suitable both in order to achieve adequate conductivity of the hygroscopic room bounding surfaces and in order to produce an adequate ion The air humidifying device should advantageously be fed with twice distilled water or rain If in fact normal tap water from the mains is condensation the surface moisture of which rapidly dries are formed in heated rooms in consequence of its mineral The dry mineral core then actually produces the impression that the air contains breathing becomes and a grey coating is formed on furniture and The humidity of the room can be kept constant not only with the aid of a humidifying but also with the aid of a drying for example if in the room itself moisture is produced by evaporated An optimum effect is achieved by using an air circulating device in the case of which the air removed from the room is dried and the air supplied to the room is to the desired degree of humidity by adding By this means it is in fact possible to achieve very accurate control of atmospheric In fresh the very fine particles of which can be correspondingly is always Embodiments of the invention will now be described by way of example with reference to the accompanying in Figure 1 illustrates diagrammatically one embodiment of the and Figure 2 illustrates diagrammatically part of a second In Figure an electrode 3 is mounted on the ceiling of a room through insulators The comprise the earthed bounding surfaces of the constituted by a floor covering wall coverings a ceiling covering 6 of hygroscopic which is electrically conductive at least with a certain moisture content in the air in the room A source of high direct voltage 7 connected by a line 8 to the ceiling electrode 3 by a line 9 to the earthed room bounding surfaces A hygrostat regulator 10 measures the humidity in the room 1 and by means of a water atomiser 11 sprays so much water into the room that the humidity in the latter is Sept at a constant for example relative Since in rooms of this type it can generally be assumed that the temperature in the room also remains tially this relative humidity also corresponds to a constant absolute atmospheric In Figure 2 a room which in respect of its electrical equipment may be arranged in the same manner as the room 1 in Figure is provided with an air circulating installation The air is sucked out through a duct and returned through a duct The humidity of the air is lowered in a drying device brought to a desired temperature in a heating or coiling device and is mixed with finely divided water in a humidifying device The heating or cooling device is controlled by a thermostat 19 in the room in such a manner that the temperature in the room 12 is kept at a desired A humidity regulator 20 controlling the humidifying device 18 keeps the humidity in the room 12 at a desired constant The drying device ensures that a determined proportion of moisture must always be so that a continuous supply of ions is also insufficientOCRQuality
