  • the deterioated environment forces us to reduce our energy consumption by 50% in home heating by the year 2020 (Bruntland Report). It has been determined that three times more people die as a result of injurious indoor air than car accidents. About 350.000 to 430.000 people need medical care as a result of bad indoor air. The connection between people who suffer with allergies and those who suffer from respiratory ailments are proven as they spend about 20 hours per day indoors.
  • Hygienic demands indicate that future ventilation has to be increased 2 or 3 times as compared to now, which means that nearly all ventilation systems are in need of rebuilding. This also signifies that ventilation in the future will absorb 50% of the home-heating costs if the heat from the exhaust air is not used to heat the fresh air.
  • the invention HYGIENICALLY DISTRIBUTED VENTILATION WITH RECYCLED HEAT AND POINT EXHAUSTION for every apartment lowers the investment cost for the rebuilding of ventilation to about one-third i.e. approximately 20.000 SEK per apartment at the same time as the equipment provides the character of a household machine for ventilation and energy saving which heat fresh air to more than 90 % with the heat energy reclaimed from used air.
  • Ventilation of larger buildings is usually accomplished by installation of a central ventilation system with natural exhaust, a mechanical exhaust, a mechanical input and exhaust-air system or a mechanical exhaust or a mechanical input and exhaust- air system combined with a heat exchanger.
  • Central ventilation system are often been dimensioned for an all-too-low air circulation which prevents a volume of hygienic air from being channelled into or out of buildings. This together with the short circuiting and stagnation in the air stream combined with the areas which have a low effectivity in air-exchange activity causes injury to people and damage to buildings. Uneven warm-air supply also brings about a situation where many apartments permanently add extra ventilation by opening windows whereas others block the ventilation in order to avoid cooling the apartment.
  • the invention is a technically new solution for a energy and climate system which gives a good indoor atmosphere, safety and high -energy effectivity.
  • central ventilation consists of a channelling between the different parts that hold the building open and which force a more expensive sectoring which can , therefore, never be made safe or separate. Therefore, it is always the ventilation system of 8 building which is the greatest danger in the spreading of fire, contamination or sound.
  • the described invention provides a completely new view of ventilation systems in large buildings which have a way of functioning which supplies the different parts of the buildings with a quality which meets the needs of air indoors.
  • the load on the building's heating system can be regulated so that better heat distribution can be maintained in the whole building.
  • the aim of the invention is to install a channelling system in the ventilation- heat exchanger, to achieve a better air distribution, better filtering, a lower noise level and at the same time make it possible to achieve a usage-friendly operation and maintenance and by providing accessibility while attending the system.
  • the electronics which steers the ventilation is adjusted so that it becomes easier to use and guides the one who is to tend the equipment in looking for faults and measures to be taken against them.
  • the ventilation system can be described in such a way that an area of a building usually an apartment, a stairway, or other premises can each be one of a building's separate ventilation's cells (fig. 1:, 10, 11 12 13).
  • the ventilation cell is equipped with a completely closeable or limited evacuation arrangements (8) which opens momentarily and releases the polluted air when such accumulates or is brought into the ventilation cell through the ventilation chimney (9) which is taken from the cells through the building's roof so that this air will not cause disadvantages.
  • This channel can also be used at the same time for ventilation's cells in the building and can be kept closed to the other ventilation cells when it isnt in use as well as when it is automatically closed off e.g. in case of fire.
  • a regenerative warm-air exchanger serves only as a ventilation cell, (Fig.1:, 10 , 11 , 12, 13), the communal air in the installations is nothing more than the increased blending of the air. Here, it is more than a matter of choice of air turnover - instead it is a matter of the risks involved in harmful communal air.
  • the opening for the outside air and exhaust air are taken up through the facade of the ventilation cell.
  • the ventilation aggregate (22+4+5) preferably the regenerative type is most suitably brought to ceiling height in the building to limit the used areas.
  • the ventilation aggregate which also provides easy cleaning, maintenance and operation is provided with a channel arrangement for the ventilation system (Fig 1: 6+7) which gives enough air turnover.
  • Blowers (17), dampers (16) and the aggregate's channel system (6+7) or the details Fig 8:23a, 27,26, 28, etc.) are to be carried out so that the generation of sound is eliminated by internal soundlosses and so that resonant sound is also prevented.
  • Movable mechanical parts such as dampers (16) and blowers (17), are placed on elastic sound- and vibration- dampening material in the aggregate (19) so that these parts lie close and tight to the bordering channel parts with centre parts of elastic sound- and vibration-dampening material (18). These parts are placed in an external height (an outer covering) (12, 14, 15) the mass and isolation layer of which give the room sound isolation from the installation's sound source.
  • the outer covering makes it possible to divide (14.+15) or open the installation easily where by it becomes possible to move the damper housing (16), blowers (17) in the regenerative channel heat exchanger (Fig 5) so that they don't hinder changing, cleaning and maintenance of the heat accumulators (3) toward the outside of the ventilation cells and the replacing, cleaning and maintaining of the filter (21) as well as the electrofilter or air heat on the channel side of the aggregate.
  • the heat exchanger technique should preferably be used since it has been shown that it is possible to save energy from the exhaust which is able to heat incoming air to over 90% efficiency through large heat.-conveying areas.
  • the corresponding annual average, for example, for the other regenerative heat exchangers lies at 65% to 86 % while the recuperative remains at 50%, however, in the latter, the degree of effectivity can be increased to 76% if considerable amounts of defrosting energy are added as these exchangers are series-coupled.
  • a sound absorber is placed in the channels trough the aggregate (28, 29, 30). This should preferably consist of high-density baked ceramic which has the ability to greatly reduce sound and thereby lower the occurrence of significant amounts of air sound. These sound absorbers or sound traps are also placed in the filter housing (5), regulating box and even, when needed, in the channel system (6+7) which lead to the different rooms or parts of the ventilation cells such as occurs in combination with air equipment ( 28) or air spreaders and aperture filters.

Abstract

L'invention se rapporte à une installation d'aération destinée à de grands bâtiments et qui est divisée en plusieurs cellules de ventilation, la ventilation de chaque cellule étant isolée du reste du bâtiment. On obtient ainsi une ventilation décentralisée et un ensemble de recyclage de chaleur ayant son propre système de canalisation pour la circulation de l'air à l'intérieur de chaque cellule de ventilation. La circulation de l'air à l'entrée et à la sortie se fait à travers la façade, de même que l'évacuation (élimination) d'un air fortement pollué, par ex. les fumées de cuisines, qui se fait momentanément, ou qui est réduite, par des cheminées de ventilation qui fonctionnent comme une ou plusieurs cellules différentes de ventilation.
