Definitions
- the present invention relates to a ventilation system for a building.
- Numerous ventilation systems are known in the state of the art.
- a first system is that in which air is extracted from the various rooms by a central unit and, optionally with the addition of further air originating from the environment, is blown back into the rooms.
- Such a system can be used only for somewhat larger buildings and demands appreciable structural modifications.
- a further system consists in the use of a single extractor in which a fan has been fitted. Ventilation openings are made in the various rooms of the building. If these ventilation openings are made relatively large, it can be guaranteed under all circumstances that a flow of air from the various rooms to the outside takes place via the central extractor. However, this requires that the central extractor has an appreciable power and extraction is also accompanied by the loss of an appreciable proportion of the heat. The latter can be compensated by installing a heat exchanger in the central extractor, but this is associated with appreciable technical and practical problems.
- US 4 742 475 discloses an air control system for a non-compartmentalised building, such as a greenhouse, wherein there is a feed system with fan and heating in the ridge, whilst a ventilation window is fitted in the side wall. There can also be an extractor fan.
- WO 01/25695 a ventilation system is described wherein air that has been blown out is fed over a heat accumulator and the heat stored therein is recovered again at a later stage.
- the aim of the present invention is to provide a ventilation system for a building that is relatively simple to implement. It must be possible to use this system easily both in new buildings and in existing buildings. On the other hand, the system must always guarantee that sufficient air is introduced into the various rooms. On the other hand, in order to be sufficiently comfortable and as far as possible to prevent heat losses, not too much air must be introduced. That is to say, the aim is to provide a minimal ventilation system so that there is no more ventilation than is necessary in order to maintain the desired climate in the building.
- a ventilation system for a building comprising at least two air blowers with adjustable flow rate, which only blow in air, each to be connected by an inlet to the outside air and to be installed in different rooms in said building, as well as a single air extractor which only blows out air and is to be installed in a further room in said building, and a control device for mutual control of said air blowers and air extractor, wherein said system is embodied for minimal ventilation and has measurement means for measuring the quantity of incoming and outgoing air, said measurement means being connected to said control device for controlling said air blowers and/or said air extractors. It has been found that for a minimal ventilation system it is essential that the amount of air that enters and/or the amount of air that is extracted is accurately known.
- control device is provided with means for converting the control signal into a signal to be transported by a mains supply and to provide the blowers with means for converting a signal received from the control device from the mains supply to a control signal for said blowers.
- a connection between a controller and the various blowers is provided with the aid of multiplexing techniques.
- these blowers are active mechanically operating fans. By drawing in air directly from the outside, it is possible to provide a continually adjusting control. The amount of air drawn in from outside can be controlled depending on, for example, weather conditions, but also on conditions in the various rooms. Because the various components operate via the mains, complex separate wiring is not necessary.
- a coupling has to be made, preferably in the meter cupboard, for the connections for the various signals superimposed on the mains for controlling the blowers. Furthermore, measures can be taken to prevent measurement/control signals being introduced into or received from the network upstream of the meter cupboard.
- the extractor by means of the control device. This is possible either via a separate cable, which in general will be present, or by means of the multiplexing technique described above.
- sensors in the various rooms These measure the conditions prevailing therein.
- An important factor is the percentage of CO 2 . This is a measure for the number of people and the activity of those people who are in a specific room. It is easily possible to measure this percentage and on the basis thereof to admit more or less air from the outside. It is also possible to determine other parameters in certain rooms, such as the humidity in a kitchen.
- a signal can be given manually to the control device if, for example, additional build-up of moisture is to be expected in the kitchen during cooking.
- Another important parameter is, as indicated above, the wind speed acting on the building. By measuring the air speed at the location of the blower, the flow rate can be corrected, that is to say the blower can start to run at a higher or lower rate. If the wind is blowing onto the blower, the energy supplied will become less and if the wind is blowing away from this a higher speed of revolution or more work on the part of the fan concerned will be required.
- This control by means of sensors can be independent of or combined with the control based on ways of life described above.
- the invention also relates to a building containing the ventilation system described above.
- the extractor is preferably connected to the wet cells of the building. Examples are toilets, showers, bathrooms and kitchens.
- the installation is used in relatively cold climates, it is preferable to warm the incoming air to avoid the sensation of draught as far as possible.
- the air is not warmed to above room temperature, but preferably to a temperature of at most 16 °C.
- the invention also relates to a method for ventilating a building, wherein air is mechanically blown into a number of rooms directly form the outside and air is mechanically extracted to the outside from at least one room, wherein the speed of air blown in is determined per blowing-in point and the mechanical work for blowing in is increased or reduced depending on this determination.
- FIG. 1 shows, diagrammatically, a building provided with the system of the invention.
- a building is indicated by 1.
- the blowers are indicated diagrammatically by 2.
- Various sockets are indicated by 3.
- the attic floor of the building is provided with a mains network 28, the first floor with mains network 9 and the ground floor with mains network 10. These mains network are on different phases and come together in the meter cupboard 4.
- An extractor 7 has been installed in the top of the building. This provides extraction for, inter alia, a shower room 8. Via the various chinks between doors and the like, extraction from the shower room 8 results in a reduced pressure in the building. However, this is negated by the action of the blowers 2. Control of the blowers 2 takes place with the aid of a control unit or central controller 6.
- radiator and blower fan shown here can also be used with other heating and air control systems, that is to say it does not necessarily have to be used exclusively with the system according to the present invention as described above.
- the air blower can comprise any known construction, such as the Sonair blower marketed by limosource. It is also possible to fit a wide variety of types of filters, ionisers and the like in the air blower.
