Description
Title of invention
Ventilation window and method for leading condensation water of ventilation device of ventilation window to the exterior
Field of invention
The invention is related to the field of building and
ventilation technology, more specifically to ventilation windows .
Technical background
IFN-Holding AG's European patent application publication
EP 2 594 725 A2 describes a window with a ventilation unit. The air inlet openings and outlet openings of the window can be in the horizontal or vertical frame or in the horizontal or vertical sash. Air travels between the inlet openings and outlet openings in air ducts made in the frame or in the sash. In this way, condensation water also travels between the inlet openings and outlet openings in air ducts made in the frame or in the sash. A heat exchanger possibly included in the ventilation window has been placed on the outside of the frame inside the body structure of the building, in a recess made on the outside of the vertical frame.
Objective of invention
The objective of the invention is to simplify the removal of the condensation water of a ventilation device integrated into a ventilation window. It is possible to solve the objective in accordance with the invention by means of a ventilation window according to claim 1 and by means of a method according to claim 8.
The dependent claims describe the preferred aspects of the ventilation window. Advantages of invention
The ventilation window comprises a) a ventilation device equipped with a heat exchanger, installed inside the frame on the vertical side of the ventilation window, b) an outlet duct which is located after the duct of the heat exchanger in the
ventilation device and which forms in the ventilation device a drain connection to the exterior.
The outlet duct comprises i) a guide, such as a trough, inclined guide surfaces and/or a funnel, arranged to guide condensation water from the mouth of the duct of the heat exchanger, ii) an outlet tube connected to the guide, and iii) an arrangement for keeping water melted. The outlet duct runs over the entire distance between the heat exchanger and the mouth of the outlet tube inside the
ventilation device and furthermore so that condensation water travels all the time downwards by gravitation and with an air flow. As compared to the window described in IFN-Holding AG's European patent application publication EP 2.594 725 A2 , the removal of the condensation water of the ventilation device now discussed, integrated into the ventilation window, is simplified, because condensation water travels all the time inside the ventilation machine and the direction of travel of condensation water is always downwards .
When the arrangement of the ventilation window for keeping water melted comprises a trace heating cable, it is possible to keep the condensation water that is formed in the ventil'ation device melted and the ventilation machine operational also during winter time.
When the trace heating cable is self-adjusting, for example so that its . resistance is proportional to the temperature, it is possible to keep trace heating on continuously. Such a
ventilation window is care-free to use, and by means of it it is possible to minimise breakages of the ventilation device occurring as a result of freezing due to human factors.
When the mouth of the outlet tube extends to the exterior, it is possible to lead condensation water out of the ventilation window to a distance from the reference surface of the external wall of the building, in which case it is possible to avoid the
running of condensation water along the surface of the external wall of the building and moisture and mould problems possibly resulting from this.
When the outlet tube has been connected or is connectable to the rainwater system or sewer system of the building, it is possible to lead condensation water in a controlled manner to water removal systems already existing in the building, in which case it is possible to avoid the getting of water to a wrong place such as the structures of the building. When the heat exchanger is a counter flow heat exchanger, it is possible to achieve a temperature efficiency of as high as 90%.
When in the method for leading the condensation water of a ventilation device of a ventilation window to the exterior a ventilation window according to any one of the preceding claims is used for removing condensation water so that the outlet duct runs over the entire distance between the heat exchanger and the mouth of the outlet tube inside the ventilation device and furthermore so that condensation water runs all the time downwards by gravitation and with an air flow, it is possible to reduce the getting of condensation water to the frame and/or sash structure of the ventilation window and/or to the body structure of the building as well as a moisture and/or mould problem possibly resulting from condensation water.

Detailed description of the invention
FIG 1 and 2 show a perspective view of a ventilation window 1, to which a ventilation device 50 has been installed. The ventilation window 1 comprises a ventilation device 50 equipped with a heat exchanger 62, installed inside a frame 2 on the vertical side of the ventilation window 1, and an outlet duct 77 which is located after the duct 62B of the heat
exchanger 62 in the ventilation device 50 (the structure of the ventilation device 50 is described in more detail in FIG 3) and which forms in the ventilation device 50 a drain connection to the exterior U.
FIG 3 shows a vertical section of the ventilation machine 50 on, the plane of the centre line of the outlet tube. The outlet duct 77 comprises a guide 75, most preferably for example a trough, inclined guide surfaces and/or a funnel, arranged to guide condensation water from the mouth of the duct 62B of the heat exchanger 62, an outlet tube 55 installed to the guide 75, and an arrangement 80, 85 for keeping water melted. The heat
exchanger 62 is most preferably a counter flow heat exchanger, but it can also be for example a cross flow heat exchanger or a heat exchanger with a rotating cell.
Condensation water forms as water vapour contained in air condenses into a: liquid on a surface the temperature of which is lower than the dew point temperature of the air passing by, in other words the temperature at which the absolute humidity contained in air reaches 100% relative humidity. In the
ventilation device 50, condensation water forms in particular in the exhaust air duct 62B of the heat exchanger 62 in a situation where the temperature of fresh air 20 is sufficiently much lower than the temperature of exhaust air 22, and fresh air 22 cools
the lamellas of the heat exchanger 62 at least partially to below the dew point temperature .
The outlet duct 77 runs most preferably over the entire distance between the heat exchanger 62 and the mouth 55B of the outlet tube 55 inside the ventilation device 50 and furthermore so that condensation water travels all the time downwards assisted by gravitation with the air flow. The mouth 55B of the outlet tube 55 extends to the exterior to a distance L, most preferably to a distance of 10-30 cm, from the external wall R of the building. It is also possible to connect the outlet tube 55 to the rainwater system or sewer system of the building.
The arrangement 80, 85 for keeping water melted comprises a trace heating cable 85, which is most preferably self-adjusting, for example so that its resistance is proportional to the temperature. The trace heating cable 85 has been presented in more detail in the perspective view FIG 4 of the electric system 80.
FIG 5 shows a view of the mouth 55B of the outlet tube 55 viewed from the top. The outlet tube 55 goes from the ventilation device 1 to the exterior U through the outlet 54 of waste air 23. The outlet tube 55 is fastened to the outlet 54 most preferably by means of a fastening element 72, which can most preferably be a screw, such as a sharp-tipped plate screw ISO 1481 - ST 3.5x13 -C or blunt-tipped -F. In the method for leading the condensation water of a
ventilation device 50 of a ventilation window 1 to the exterior U, a ventilation window 1 according to any one of the preceding claims is used for removing condensation water so that the outlet duct 77 runs over the entire distance between the heat exchanger 62 and the mouth 55B of the outlet tube 55 inside the ventilation device 50 and furthermore so that condensation water travels the entire distance downwards with an air flow assisted by gravitation.
The invention should not be understood to be limited only by the below claims, but the invention is to be understood to include
all their legal equivalents and the combinations of the embodiments presented.
