Definitions

  • the present invention relates to a ventilating unit for use on the inner side of an outside wall of a building, which ventilating unit comprises a passage for passing outside air through the outside wall, control means for regulating the amount of outside air that is admitted through the passage, and a control unit for controlling said control means on the basis of the pressure difference between the inside and the outside of the building.
  • Such a ventilating unit is known from practice, and it functions to provide a natural and comfortable ventilation of buildings, and in particular of office buildings.
  • a constant ventilation flow which reduces any nuisance caused by draught, can be obtained by means of said control unit and the control means, which consist of a ventilation grille. Since the unit is built into an outside wall of the building, a complicated system of tubes is not needed, which makes it possible to keep costs low and reduce the risk of sick building syndrome, which is caused by long, contaminated ventilation ducts, in which germs can accumulate and develop.
  • the object of the invention is to provide a ventilating unit which enhances comfort even more and which is furthermore capable of effecting an energy saving.
  • the ventilating unit according to the invention is characterized in that said ventilating unit is provided with a passageway, which extends between the passage in the outside wall and the bottom side of a heating element when the ventilating unit is installed, whilst the control means are mounted in said passageway.
  • the ventilating unit is provided with a temperature sensor which is connected to the control unit, which sensor may be mounted near the upper side of the heating element, for example, where the ventilating air can flow past the sensor.
  • the ventilating unit can be controlled not only on the basis of the pressure difference between the outer side and the inner side of the outside wall, but also on the basis of the temperature. It is possible to arrange thereby that the temperature of the outflowing air above the heating element must not fall below a preset value, which value is preferably adjustable, between 12°C and 20°C, for example. If the temperature falls below the preset value, the amount of outside air that is admitted will be reduced until the preset temperature is reached again.
  • a preset value which value is preferably adjustable, between 12°C and 20°C, for example.
  • outside temperature As a measure for the control precision.
  • a high control precision may be selected, whilst the control precision will be lower when the outside temperature is high.
  • This aspect makes it possible to reduce the amount of adjusting movements of the control means, which saves energy and prolongs the life of the moving components of the control means.
  • Another possibility is to make this a "sliding" influence, wherein control can be made dependent of the number of movements of the control means in a preceding period.
  • the control means preferably comprise a valve which is mounted in the passageway, and which is capable of shutting off said passageway or releasing it partially or completely. It is advantageous if the valve can also be manually controlled. When the valve is closed, the control system will be disabled. On the other hand it is possible to put the valve in the open position, but in that case it is preferred to provide a frost protection device, which closes the control means if the exit temperature falls below 3°C, for example, in order to protect the heating element, which generally works with water, against freezing.
  • Fig. 1 is a ground plan of a house which is fitted with a number of ventilating units according to the present invention.
  • Fig. 2 is a larger-scale front view of a ventilating unit according to the invention, which is installed between an outside wall and a heating element.
  • Fig. 3 is a side view of the unit of Fig. 2.
  • Fig. 4 is a view which corresponds with Fig. 3, without the outside wall, however, wherein the air flow through the ventilating unit and the heating element is shown.
  • Fig. 5 is a larger-scale perspective view of a separate ventilating unit.
  • Fig. 1 is a ground plan of a house, in which the present invention is used.
  • the house has two outside walls 1, on which heating elements 2 are mounted in the various rooms.
  • Said heating elements may be independent heating elements, but generally they will form part of a central heating system, and in that case the heating elements 2 will consist of radiators, in which water heated by a boiler provides the supply of heat.
  • a passage 3 has been formed in the outside wall 1 at the location of each heating element 2, which passage functions to pass outside air through the outside wall 1 into the interior of the house for the purpose of ventilating the house.
  • Each passage 3 gives way to a ventilating unit 4, which is disposed between outside wall 1 and heating element 2 in this case.
  • the exhaust of air takes place via exhaust channels 12, which may or may not be fitted with an exhaust fan.
  • ventilating unit 4 is provided with a passageway 5, which extends between passage 3 in outside wall 1 and the bottom side of the associated heating element 2 when the ventilating unit 4 is installed.
  • Heating element 2 is internally provided with a vertical passage 6, so that rising air can be heated from two side over a long distance before it enters the room of the house or other type of building.
  • ventilating unit 4 is fitted with a (preferably electronic) control unit 7 (Fig. 5), to which control means, in this case in the form of a valve 8, are connected.
  • the valve may be capable of stepless operation, or it may close or open the passageway 5 of ventilating unit 4 partially or entirely in a number of steps.
  • the control unit is set for controlling valve 8 on the basis of the pressure difference between the inner side and the outer side of outside wall 1 of the house, in order to obtain a constant flow of outside air when pressure differences vary.
  • passageway 5 of ventilating unit 4 comprises an upward portion 5' and a downward portion 5'', and slide valve or rotary valve 8 is provided near the transition between the two portions 5' and 5''.
  • the valve is driven by means of an electric motor 9, which is connected to control unit 7, or by another drive unit for adjusting the valve 8.
  • Ventilating unit 4 is fitted with a sensor 10, which is capable of measuring the pressure difference between the two sides of the outside wall, on the basis of which pressure difference valve 8 is controlled so as to obtain a desired air flow, for example a more constant or less constant air flow.
  • Ventilating unit 4 is to that end provided with a temperature sensor 11, which is mounted near the place where the heated air exits heating element 2, in this case near the upper side of heating element 2.
  • This temperature sensor 11 makes it possible to ensure that the temperature of the outflowing air will not fall below a preset value, whereby said preset value may for example be a temperature selected from a possible range of 12 - 20°C, for example 15 to 16°C. Usually no draught problems occur with exit temperatures within this range.
  • the power for the electric motor 9 and the control unit 7 may be taken from the existing electricity grid, but it is also possible to use a separate direct current power supply, a battery or a solar cell, for this purpose.
  • said units may be coupled, and if said units are used in combination with a central heating system, they may also be coupled to the boiler, so that the temperature control of the central heating system takes place in cooperation with the control of the heating unit. All this depends on the particular use. In newly built houses or in office buildings more central facilities can be provided that in existing houses, where one or more ventilating units according to the invention are added later on, for example when carrying out a renovation project. Of course several variations and additions are possible on the basis of the present principle.
  • a filter for filtering the inflowing air may be incorporated in ventilating unit 4, said filtering may take place electrostatically, for example, but also mechanically or otherwise.
  • the generation of a ventilating flow may take place in a natural manner, but on the other hand it is possible to build in exhaust fans so as to effect mechanical ventilation.
  • the ventilating unit may be fitted with means which ensure that the valve will be closed if the supply voltage is cut off, this in order to prevent an undesirable inflow of air and freezing of the water in heating element 2.
  • Said means may comprise a capacitor, for example.
  • the invention provides a ventilating unit which is capable of providing comfortable and energy-saving ventilation of houses and other buildings, without large investments being required, whilst the ventilating unit can also be built into existing buildings without any difficulty.
