Abstract

A wall-mounted radiator (1) includes a supply air device which conducts outside air from an external wall opening (4) along an air duct to a radiator outlet (5) while heating the air with the aid of a heating body (10). The radiator includes a particle filter (9) and a fan (12). The air duct also preferably includes a room air inlet opening (7), so that outside air and room air will both be driven through and cleansed by the article filter (9). The air flow cleansed of its particle pollutants is then passed through a carbon filter (20). The air duct may also include a connection opening (8) which enables the exhaust air flow to be passed through the particle filter of the radiator, this filter conveniently being an electrofilter.

Description

A radiator arrangement including filters.
The invention relates to a radiator arrangement of the kind defined in the preamble of Claim 1.
Unfortunately, the ambient air of urban areas, cities, towns, etc. , is often polluted with particulate, gaseous and vapour- form pollutants such as pollutants which derive from vehicle emissions, to such an extent that the ambient air is no longer suitable for direct introduction as supply air into the rooms of, for instance, high-rise apartments/flats, office buildings or the like, even when the contaminating solids have been filtered out. Consequently, it has been found appropriate to improve cleansing of the air with the aid of more effective apparatus. However, because such apparatus are both complex and expensive, all of the supply air to an apartment is cleansed, or purified, centrally and then distributed to the separate rooms in the apartment block through a system of air ducts.
However, in this regard it has also been found that the duct system used to distribute supply air to individual rooms from a central ambient air cleansing plant also represents a serious health hazard, in addition to demanding the high costs aforementioned.
On the other hand, it has not earlier been possible to introduce ambient air from an urban district environment directly into a room through a supply duct which extends through the external wall of said room, precisely because of the aforementioned airborne pollutants.
Admittedly, the advantages that are afforded by introducing ambient air through an external wall and bringing the air into contact with a radiator which heats the air to a comfortable temperature before the air is released into the room have earlier been achieved. In this regard, it has also been suggested that particle filters are used to extract particles from the ambient air prior to the air entering the room via the radiator. However, as before mentioned, known radiator constructions cannot be used when the ambient air concerned is also contaminated to a large extent by gaseous and vapour-form pollutants.
The object of the present invention is to provide a radiator arrangement which will enable ambient air that is contaminat- ed with particle pollutants, gaseous pollutants and vapour- form pollutants originating from vehicle emissions for instance, to be used nevertheless as supply air, said radiator being constructed to release to the room concerned air in which the concentrations of foreign vapours and gases, such as NOX, have been reduced to acceptable levels, the particle concentration of said air also being reduced to an acceptable level at the same time.
This object is achieved with a radiator arrangement of the kind defined in Claim 1.
One important feature of the invention is thus that the radiator arrangement is constructed to receive ambient or outside air as supply air for a room of a building, wherein said ambient air is first filtered through a particle filter and the air thus cleansed of its particle pollutants is passed through a carbon filter before being released into the room concerned.
It has surprisingly been found that with the aid of an essentially conventional particle filter of acceptable complexity and cost level, it is possible to cleanse the supply air of its particle pollutants to an extent such which enables the supply air to be further cleansed in practice with the aid of a carbon filter on which the gaseous pollut¬ ants, for instance NOX, can be adsorbed under conditions which allow the carbon filter to have a useful life span acceptable in practice. The invention thus surprisingly solves the problems which have earlier made it impossible to use radiator arrangements of the kind defined in the intro¬ duction and also achieve the exceptional advantage of no longer needing to use a central supply air system with associated central and expensive air-purifying apparatus and without needing to suffer the health hazards that are associated with such known central supply air systems.
The particle filter device included in the inventive radiator arrangement includes a true particle filter arrangement which may advantageously include an electrofilter, such as an electrostatic filter, which is particularly suited for extracting fine dust and small particles.
The particle filter device may also include a so-called crude filter at the upstream end of the supply air device, for crude extraction of airborne seeds, such as birch seeds, etc.
It has also been found that the amount of airborne contami¬ nating particles present in a room in which ambient air has been introduced as supply air via a known type of radiator construction but without the presence of a crude air filter, only about 30% of the air-contaminating particles in the room have been carried thereinto by the supplied ambient air, while the remaining 70% of the particles present in the room air have entered the room from other sources, such as from textiles, furnishings etc.
In accordance with the invention, the concentration or amount of contaminating particles can therefore be reduced in the air in a room to which ambient air has been delivered while being filtered and while being heated in the vicinity of a radiator according to Claim 1, by virtue of the fact that the radiator is provided with means which causes a flow of room air to circulate through a partial filter device adjacent the radiator, this device preferably also being adapted to treat the incoming flow of ambient air.
Thus, in accordance with one embodiment of the invention, the inventive radiator may include an ambient air inlet duct, optionally a crude filter for filtering ambient air that arrives at the radiator, a room air inlet duct, a mixing chamber for mixing ambient/supply air and room air, and blower (fan) means for blowing the fresh air and a preferably selectable flow of room air through the particle filter device and then through the fine filter.
According to one preferred embodiment, the filter device includes an electrofilter, for instance an electrostatic filter, which enables small particles to be extracted effectively from the passing air flow, and then particularly small particles that remain in the fresh air flow' after passing through the crude filter. Since an electrofilter will require a supply of electric current, this supply can also be used beneficially to enable the use of an electric fan arrangement adjacent the radiator.
Thus, according to the invention, the filter device of the radiator arrangement not only functions to extract particles from the crude filtered fresh air delivered directly to the radiator but also functions to extract particles from the air present in the room in which the radiator is installed.
According to one embodiment, the radiator may conveniently be provided with means for generating positive air ions.
This means may be implemented readily in the embodiment which includes an electrofilter, wherein said means may, for instance, have the form of a rod antenna connected to the high voltage source of the filter.
The radiator is also preferably constructed to enable it to be carried away, for instance to be collapsed outwardly from its wall mounted position, so as to expose the air supply device and the fresh air duct extending through the^wall, for cleaning purposes, among other things.
In this regard, the radiator is preferably collapsible about a generally horizontal hinge axle located at the bottom edge of the radiator, so that the fresh air duct, which is normally located in the region immediately beneath the upper edge of the radiator, can be reached easily for cleaning purposes, and also a crude filter located adjacent the fresh air inlet. The electrofilter may also be made accessible for cleaning purposes or for the purpose of replacing a dust collecting element, for instance by virtue of being able to move the radiator away from its wall mounted position.
The means used to propel the air through the radiator may include a conventional blower or fan, although it will be understood that instead of using a fan having a rotary impeller there may be used alternatively other known flow generating means.
According to one particularly favourable embodiment of the invention, the radiator is provided with an air duct connec¬ tion opening upstream of the filter device, this connection opening being particularly adapted to enable the connection of an exhaust air hose from a dust extracting vacuum cleaner, such that the exhaust air flow from the vacuum cleaner can be passed through the electrofilter in the radiator arrange¬ ment and therewith cleansed.
As a result of the inventive connection opening for connec¬ tion of the exhaust air hose of a vacuum cleaner, the invention offers an alternative to a central dust suction plant which would otherwise constitute the only realistic alternative for eliminating the extremely small particles that pass through a conventional dust extracting vacuum cleaner. The invention will now be described in more detail with reference to exemplifying embodiments thereof and also with reference to the accompanying drawing.
Fig. 1 is a schematic vertical sectioned view of a wall- mounted radiator constructed in accordance with the invention. Fig. 2 is a schematic section view taken on the line II- II in Fig. 1. Fig. 3 is a schematic sectioned view which illustrates the air mixing chamber of the radiator.
Fig. 1 shows a radiator 1 mounted on the inside of an external wall 2, beneath a window 3. The wall 2 has provided therein a through-penetrating opening 4 through which outside ambient air is introduced to the radiator 1. The radiator 1 includes a radiator body 10 which is heated by passing warm liquid through the radiator or by resistive heating of resistance wires or by some other suitable heating means.
The radiator body 10 is provided with a housing 11 which together with the radiator body 10 forms an air duct between the opening 4 and a warm air outlet 5. The housing 11 is provided on the rear side thereof with an opening 13 having a defining edge 14 within which the air duct 4 discharges, wherein the housing may be fitted flush with the inner surface of the wall 2 so that its opening defining edge surrounds the fresh air opening 4. As shown, the radiator body 10 is provided with surface-enlarging elements 101 on its rear side and with similar elements 102 on its front side. The ambient air opening 4 is shown to open out in the proximity of the upper edge of the housing and the housing is constructed to conduct the fresh air firstly through a crude filter 16 and then downwardly into surface-enlarged contact with the rear side of the radiator body 10 while preheating the fresh air, whereafter the fresh air flows into a mixing chamber 6, which has a room air inlet 7 and a connecting opening 8 for the connection of an exhaust air hose of a vacuum cleaner. The chamber 6 communicates with an electrofilter 9, and the exhaust air leaving the filter 9 communicates with a fan or blower 12, preferably a cross-flow fan, which drives the air up along the front side of the radiator body 10 so as to bring the air into surface-enlarged contact with the elements 102, and then to drive the air through a carbon filter 20 which adsorbs airborne pollutants, particularly gaseous pollutants, such as NOX, whereafter the air finally leaves the radiator arrangement through the outlet 5 at the upper end of the radiator 1. The carbon filter 20 is conveniently mounted adjacent the outlet 5 in a manner which enables the filter to be replaced. The room air inlet 7 of the mixing chamber 6 may be adjustable, so as to enable the volume of room air that is drawn through the filter 9 by the fan 12 to be adjusted as desired.
The filter 9 includes a high voltage unit, and a rod antenna 19 or some like device is suitably connected to the high voltage unit so as to generate positive air ions in the room air and therewith reduce the hazards associated with the presence of radon daughters in the room, particularly when the air is cleansed effectively of its small particle content.
As shown in Fig. 3, the connection opening 8 may include an associated valve means 81 having a valve flap which is biased towards a sealing position over the opening 8 by means of a pivot bearing 83 and a spring 84, wherein the bearing 83 and the opening 7 are arranged so that when fitted in the opening 8, the nozzle 88 on the exhaust air hose 89 will swing the valve flap 82 to a position in which it seals the opening 7 against the action of the spring 84.
The illustrated embodiment is of a principle nature and the person of normal skill in this art will realize that the actual construction of the radiator arrangement can be varied without departing from the inventive concept as expressed in the Claims. Naturally, the fan 12 may equally as well be placed at the upper part of the radiator as in the illustrat¬ ed position, and when the air flow through the radiator is established with the aid of external fan devices, the suction of room air in through the opening 7 can be achieved with the aid of an ejector arrangement or by similar means. Although the construction of the radiator body 10 and the manner of its suspension are of subordinate significance, it is naturally beneficial to drive the air into surface-enlarged contact with the radiator body 10 and its surface-enlarging elements, and it is also preferred to construct a supply air device and the radiator housing in a manner which will prevent the discharge of air at locations other than at the intended radiator air outlet 5.
The radiator body 10 is provided with typical control means for controlling the amount of heat emitted by the radiator to the by-passing air .
Fig. 1 shows schematically the radiator suspended on the wall by means of a hinge 17 having a horizontal hinge axle at the lower part of the radiator which enables the radiator to be swung away from the wall so that the area between the radiator body and the wall can be cleaned, and then particu¬ larly the duct 4 and any crude air filter 16 or the like that may be connected to the duct.
The radiator is latched in its working position by means of a releasable latching device 18 active between the wall 2 and the upper end part of the radiator.
The carbon filter 20 may conveniently have an enlarged, exposed surface on its upstream side. For instance, the filter may have a porous or a fluffy structure at least on its upstream side, so that the carbon filter will retain a long useful life despite the dust and other particles contained in the passing air flow. The carbon filter per se may also form the particle filter of the radiator, although the best embodiment at present is one in which the particle filter and the carbon filter are separate from one another.
