Abstract

The windowsill system has a windowsill (1) having a surface (3) forming an air duct (2), with a ventilation channel having a fan. The air duct (2) is parallel to the inner wall of the space is air conditioned. The air duct (2) has a channel (6) which branches in the direction of outdoor air.

Description

The The invention relates to a sill, which is mainly used in energy-optimized buildings is used, these are buildings with high thermal insulation. By a controlled ventilation should a pleasant room climate and the prevention of mold growth be achieved. The system window bank is due to production as serviceable body to disposal, which by mounting the equipment for the respective application is completed.

To the Heating or cooling or for the air conditioning of interiors, there are many possibilities. In view of the still to be presented technical solution only briefly on the air circulation To be received. The air is either from the heated / too cooling Room or sucked in as fresh air, heated by water or other energy sources / cooled and returned to the room (Convection principle). Instead of heating / cooling the sucked air can by using a known heat exchanger, the temperature the air and thus the space in question.

to Preventing the formation of mold on the one hand no humid air be present and on the other hand should help to create a healthy Indoor climate the air should not be too dry. At the respectively desired Temperature should be given the appropriate relative humidity be.

to Realization of heating or cooling (ventilation) gives It is relatively complicated and thus expensive facilities or devices. In general, the principle is maintained that the radiator below the window is arranged, because it is (apart from the heat radiation) thereby once caused a vertical air movement and further an air circulation.

It It is therefore an object of the invention to propose a system window bank, which is manufactured so that without further processing or editing a main body to disposal stands, which equipment technology completed in such a way becomes that with it the basic function, namely the air conditioning can be done and supplementary Other functions in the sense of home technology can be adopted. The proven Principle that a radiator advantageously arranged below or near the system window sill is, should be maintained.

According to the invention Task solved as follows, being with regard to the fundamental inventive thought up Reference is made to claim 1. The further embodiment of Invention results from the claims 2 to 10.

to Further explanation of the invention, the following should be executed.

Of the body the system window sill is preferably an extrusion process produced semi-finished product made of fiber-reinforced plastic. The cost-effective production in a twin-screw extruder carried out by moistening and compaction of wood fibers or hemp shives with a matrix polymer and subsequent shaping in one Tool, its opening the desired Semi-finished cross-section corresponds. Through a downstream coextrusion stage can the surface functional and / or aesthetic in a manufacturing process be modified.

This body exists - like in the embodiment even closer is stated - off a ventilation duct with molded contact surface, the ventilation duct with contact surface represents the actual windowsill. The bearing surface is a hollow chamber profile with reinforcing ribs. This is the stability the bearing surface guaranteed at low weight of the system window sill.

Of the ventilation duct We arranged parallel to the inner wall of the room in question. At one end of the ventilation duct a fan is installed. This fan can be switched in the direction of rotation be and is speed controllable. This is a controlled and venting possible.

Corresponding In one variant, the system window bank is designed such that branches off a channel parallel to the inner wall arranged ventilation duct, making a connection (possibly through a flanged channel extension) to the outside air he follows. The discharge Exhaust air or suction of fresh air is given. About sensors and possibly additional Evaluation technology it is possible considering the interior temperature, the temperature of the outside air and the respectively existing one relative-humidity the desired Parameters in the interior, namely To set the temperature and relative humidity as far as possible, so that a comfortable indoor climate is created

According to a further variant, in the case where two windows are arranged side by side, placement of two system window banks side by side is proposed in order to create a long sill. Of course, the bearing surfaces abut each other conclusively, while on the interior side the abutting ventilation ducts are separated by a miter. In the area of these miters is the access to the fans, the connections, the Zulei cabling, etc. possible.

The Invention will now be explained with reference to embodiments.

The system window bank 1 according to 1 as a basic body consists of the ventilation duct 2 and the bearing surface 3 , The bearing surface 3 has reinforcing ribs for stabilization 4 , On each side of the ventilation duct is an insert 5 arranged. On this insert are (outwardly arranged) ventilation grille 7 placed, which are provided with vents, ventilation holes or similar air passage possibilities, as is the case 3 results. The ventilation grilles 7 are manually adjustable and give the air flow the desired direction. Seen from the outside behind the insert 5 is on one side of the ventilation duct 5 a fan (not shown) arranged. As already said, its speed is adjustable and switching the direction of rotation (and thus the change of the flow direction of the air) possible.

In the system window bank according to 2 branches from the ventilation duct 2 a leading to the outside air duct 6 from. It remains the respective execution reserved, whether according to 2 the ventilation duct 6 from the ventilation duct 5 branches off at a right angle or leads arcuately outward. With an air exchange over the channels 2 and 6 must the ventilation grille 7 , which is located in the ventilation duct 2 closed to the fan.

It is suggested at the end of the ventilation shaft 6 leading to the outside, possibly flanging an extension that terminates with the outer wall. In this extension, an air filter can be installed and provided at the outer end of a conventional insect screen.

It should be emphasized that by the bearing surface 3 , which is designed as a hollow chamber profile, various cables can be passed through the chambers, z. As electric cables, telephone cables, data transmission cable.

at the juxtaposed system window sills can this advantageous Type of wiring through the hollow chambers also done. The accessibility is, as already said, given by the mitres in the ventilation ducts.

Proposals are still to be made which mean a multifunctional use of the system window bank:
In the bearing surface 3 Solar modules are integrated with the aim of self-sufficient power supply (about 60 W per running meter).

The outer surface of the ventilation duct 2 is used for orientation lighting. The lighting is also used for ground illumination.

In summary can be said that it is through the system window bank according to the invention possible is cheaper, with relatively simple design and installation equipment technology To achieve good results in the air conditioning of interiors. become.
