Definitions

• the invention relates to a window ventilation device (claim 1, claim 27), which is able to exchange air between an exterior space and an interior and thereby "improve" the air quality in the interior.
• the window ventilation device is not more than area-wise installation in the profiled frame allows and there are elements of the fixed (immovable) frame used as hollow chambers in the form of flow channels for the air duct for heat and / or moisture exchange.
• a laterally projecting housing is provided, whose wall sections both define the housing and also determine at least two flow paths in an interior of the housing which intersect within the housing, presumably in an intersection area (there 3). On one narrow side are two (there 8, 9), and on two other, opposite (narrow) end faces are two more (there 6)
• a problem of the claimed invention is to realize the covert installation of such a window ventilation device on site. It is not intended to be fully integrated into the fixed frame, but must protrude in areas (in terms of volume). Despite the window ventilation device in the fixed frame (frame) is the
• the solution can be found in claim 1 or claim 27 or claim 28.
• the hollow profile is used to complement the description of the adaptation, design and suitability of the window ventilation device as such (and its working method).
• the claimed window ventilation device requires four openings (understood in the general sense also "outlets”, which also include an inlet, just abstract in the sense of a “flow opening” as the opening area).
• Two flow openings are to be provided to the outside (not: directed), with a view of the wing as parting plane, "outside" in the sense of the weather-dependent side.
• the window ventilation device is easy to maintain, which is required for replacement of filters or heat exchanger elements or electronic components from time to time.
• the window ventilation device is also suitable to be placed in a middle Ipfosten (in the sense of a widening profile).
• the outside of the frame is also suitable to be placed in a middle Ipfosten (in the sense of a widening profile).
• the term of the window is also to be seen as a French door or door as such.
• the term of the window is functional to look at, so provided with a glass insert, which should not be reduced according to task and at the same time to achieve ventilation on his profile frame (fixed frame).
• Sensors can be provided (claim 22). Two sensors can be used in conjunction with the electrical circuit on the board to detect the installation position of the ventilation unit, as a "device” mounted on the right or left of the profile frame (frame) without having to define the right or left device in the production. So it can only be one
• Temperature sensors for an antifreeze strategy may also be present to protect the ventilation unit from icing during operation.
• the antifreeze strategy (claim 23) for avoiding icing of the ventilation device by control measures is as follows.
• a temperature sensor in the exhaust air duct (the channel that leads the air to the outside) is arranged. Since it is not known before the final installation, whether the ventilation unit is mounted on the right or left of the fixed frame (frame), two temperature sensors, one in each example outermost Stömungskanal be mounted. During final assembly, an installer adjusts the unit to a left or right ventilation unit, and the control system selects the right sensor as the "outgoing sensor" (FO outward sensor).
• the electronic / electrical control operates with a hysteresis of a few ° C, for example between 2 ° C to 4 ° C.
• the exhaust air temperature the temperature of the exhaust air FO
• a set first value of z. B. 2 ° C drops
• the electronic control on the board in response to a fan speed (speed) down the supply fan (fan for the air CLOSED), in particular completely off.
• the supply air fan is again at the same stage (at the same speed) as the exhaust fan (the fan of the exhaust air AB, which is the exhaust air FO after the heat exchanger).
• the ventilation unit can be of symmetrical design and it is not known before final assembly how it is installed, there may be a possibility that the unit tunes the volume flows to the respective mode (right / left). The installer therefore adjusts when installing the housing, whether it is a right or left installation.
• the on-board electronics can regulate the fans so that the top fan is operated as an exhaust fan and the bottom fan as a supply fan.
• the supply air fan is set to a slightly lower speed, so that it is ensured that there is no supply air surplus in the interior (outlet from CLOSED).
