Definitions
- the present invention relates to a method for providing clean or pure air in premises, wherein unclean or impure air is received in an air-treatment device from lower portions of the premises and cleaned or purified therein.
- the invention further relates to a device for carrying through said method.
- the object of the present invention has been to eliminate this problem and this is done by providing the method according to the invention with the characterizing measures of subsequent claim 1.
- a device for carrying through said method is given the characterizing features of subsequent claim 22.
- fig. 1 schematically illustrates premises with a device according to the invention
- fig. 2 is a side view, partly in section, of a device according to the invention
- fig. 3 is a section of an air discharge or air emit- ting unit forming part of the device of fig. 1
- fig. 4 schematically illustrates a cooling device forming part of the device of fig. 1.
- an air treatment device 1 having a chassis 2 with driving wheels 3 for moving iQ o ⁇ fl 0 0 o ⁇ P ) CQ ⁇ Cfl H- 1 ⁇ rt a 4 • a ts ⁇ JD rt if rt
- the cooling device 13 is provided to cool the first partial flow DS1 to such temperature relative to the tem- perature of the air in the premises where the cooled air KL shall be discharged, that said cooled air KL will sink slowly, through a cell body member 17 forming part of the air discharge unit 15, for generating the zone of clean air RZ without thereby substantially co-eject impure air from the surroundings into the zone of clean air RZ and preferably without generating substantial turbulence in the air in the premises.
- the heating device 14 is provided to heat the second partial flow DS2 to such temperature relative to the te - perature of the air in the premises where the heated air VL shall be discharged, that said heated air VL slowly rises upwards towards the ceiling region TR of the premises without thereby causing substantial turbulence in the air in said premises .
- the zone of clean or pure air RZ may constitute or define parts of a breathing zone A for a person 18 which e.g. lies on a bed 19 or similar, but said zone of clean air RZ may also be another zone where clean air is needed, e.g. a working zone wherein work is done.
- the cooling device 13 may be a thermoelectric device with Peltier-effect, i.e.
- thermoelectric device with cooling members 13a and heat emitting or exothermal members 14a.
- the cooling members 13a are in this case the cooling de- vice 13 from which the cooled air KL is discharged and the heat emitting members 14a are defined by the heating device 14 from which the heated air VL is discharged.
- the cooling device 13 may be controlled by a control device RC which cooperates with a transmitter 20 which is situated on the same or substantially the same level as the breathing zone A or similar and preferably at a location or point outside said zone.
- a control device RC which cooperates with a transmitter 20 which is situated on the same or substantially the same level as the breathing zone A or similar and preferably at a location or point outside said zone.
- the control device RC cooperates with a transmitter 21 which is situated in the air passage branch 10a downstream of the cooling device 13.
- the transmitter 21 is adapted to measure the temperature at said level and, based on the measurement result, transmit a signal to the control device RC.
- the control device is adapted to cont- rol the cooling device 13 based on the temperature at said level.
- the transmitter 21 is preferably a set point transmitter which is set or adjusted to a certain set point temperature for the processing air.
- the fan device 12 is adapted to bring the processing air to flow through the air treatment device 1 such that the air flow overcomes the resistances therein, but not such that the air flow is pressed or forced out through the air discharge unit 15.
- the air discharged from the air discharge unit 15 does not become substantially turbulent and does not co-eject impure air from the surroundings .
- the cell body member 17 of the air discharge unit 15 preferably has a porous outer cell body layer 17a and a porous inner cell body layer 17b.
- the outer cell body layer 17a is preferably harder and has larger pores than the inner cell body layer 17b such that said outer cell body layer 17a defines a supporting part of the cell body member 17 and provides for a smaller fall of pressure for the passing processing air than the inner cell body layer 17b.
- an air guide means 22 which, relative to the incoming flow of processing air, has a transverse member and which
- the heated air VL is brought to flow upwards such that it forms an upper layer of air Ll closest to the ceiling and this upper air layer Ll is brought to keep a temperature of preferably about 22°C.
- air is sucked into the air treatment device 1 from a lower layer of air L2 closest to the floor 4 and having a lower temperature than the upper air layer Ll, and said lower air layer L2 preferably has a temperature of about 20°C.
- Air is brought to fall or descend at low speed and without turbulence from the upper air layer Ll to the lower air layer L2 preferably through an intermediate air layer L3 which might have a temperature of about 21°C.
- An alternative embodiment not described above might include that the air purifying device 11 can purify air in another way than by filtration and the air therein may be treated with radiation or ionized or provided with moisture and/ /or medicine. About half the air taken in into the air treatment device 1 is discharged or emitted as cooled air KL and about half as heated air VL.
- the cooling device 13 may be another cooling device than a thermoelectric device.
- the air discharge unit 15 may have another form than the one described and shown and it may include one or more cell body members 17 and/or cell body layers . There may also be more than one air discharge unit 15.
- the breathing zone A or similar may be another area wherein clean air is needed and instead of air or in connection therewith, a protective gas may be used.
