BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a method and apparatus for ventilating a building. More particularly, the present invention relates to a method and apparatus for ventilating a building wherein a pressure that is different than the outside pressure is induced in certain rooms of the building.
2. Description of the Prior Art
In most of the buildings in use today it is a problem to secure ventilation of the buildings under all circumstances. Particularly, in buildings to be heated the quality and quantity of the replacing air and the distribution of the replacing air into different rooms is often poor. In air conditioned buildings, the problems are the disadvantages caused by humidification of constructions and the arranging of the ventilation in a reliable way. When endeavouring to heat the replacing air brought in from the outside advantage is not sufficiently taken of the energy contained in the walls.
When using mechanical air-conditioning apparatuses air from the inside of the building is continuously removed and replacing air is brought inside. The replacing air must be either heated or cooled off, depending on the circumstances, prior to introducing it into the room spaces, and into the inlet channels for the replacing air. Different kinds of set-ups are arranged for these purposes. Similarly, air from the room spaces must be removed with the help of different kinds of equipment. These types of tube networks, channels made for the leading of the air, and the cleaning, cooling or heating apparatuses are expensive and bulky, and their mounting, cleaning and maintenance require much time and costs. Additionally, the heat energy contained in the interspace between the ceiling and the roof is not sufficiently taken advantage of for heating the replacing air. One problem is also the costs arising from the air-conditioning operation when using mechanical air-conditioning for bringing-in and removing the air.
SUMMARY OF THE INVENTION
It is an object of the present invention to bring about a method for arranging the ventilation of a building, by which method some above mentioned disadvantages of the present methods are eliminated. In particular, it is an object of the present invention to bring forth a method, which require no expensive tube systems and/or channels for the transport of either replacing or exhaust air. Additionally it is an object of the present invention is to bring forward a method which easy to use and dependable in operation. Further an object of the present invention is to bring about a structure that is favourable to produce and the air-conditioning of which works efficiently and reliably.
According to the invention, air under higher pressure led from one side to the other side of the wall mainly through the air permeable insulating materials of the wall and is directed by means of directing materials, which are essentially less air permeable compared with the insulation materials in the wall. When there is an under-pressure in the room space the air flows through the wall from the outside indoors. Correspondinggly, if there is a positive pressure in the room space, the flowing direction is from the indoors out.
When endeavouring to heat the buildings, the replacing air must be heated before leading it into the room space. In the method according to the present invention the replacing air is led through the wall, when an underpressure is induced in the room space. In this way the replacing air is at the same time heated by the heat energy contained in the wall of the building. The air is led through an opening formed in the outer wall of the building on and is directed by the insulation materials indoors. When using the method of the present invention no particular replacing air channels or heat exchangers are required, because the wall of the building is functioning both as an air channel as a heat exchanger. During the heating season the replacing air is taken mainly through the walls, but during the warm period, e.g. in the summ
