Abstract

A device for heating supply air for the ventilation of a room, which is supplied with supply air from a glazed balcony located adjacent to the room, has an outer balcony parapet (5), which is permeable to the heat radiation of the sun, and a heat-absorbing inner balcony parapet (12) located inside the outer balcony parapet (5) and adapted to be heated by the solar heat radiation that penetrates the outer parapet. The outer and inner balcony parapets (5, 12) define between them a substantially vertical air gap (13). A fan arrangement (16) is adapted to force air present in the glazed balcony through the air gap (13) from the lower part thereof to the upper part thereof for heating of said air. Inner outlets (19) are arranged in the upper part of the air gap (13), through which outlets the heated air is allowed to flow out into the glazed balcony before being supplied to the room as supply air.

Description

DEVICE FOR HEATING OF AIR IN A GLAZED BALCONY
Technical Field
The present invention relates to a device for heating supply air for the ventilation of a room, which is supplied with supply air from a glazed balcony located adjacent to the room.
Background Art
When heating the veranda that is formed by a glazed balcony it is common today to use, in particular, heating elements such as electric heaters, LPG heaters and IR heaters. In the case where the heated air of the ve- randa is used as supply air for the ventilation of an indoor room located adjacent to the veranda, the temperature of this room will of course also rise slightly.
Summary of the Invention
The object of the present invention is to provide a device which in a simple and inexpensive manner heats the air of a glazed balcony that is utilized as supply air for the ventilation of an adjoining room and thus also contributes to heating the veranda that is formed by the glazed balcony.
This object is achieved according to the present invention by a device, which is of the kind stated by way of introduction and which is characterised in that it comprises
an outer balcony parapet which is permeable to the heat radiation of the sun,
a heat-absorbing, inner balcony parapet located inside the outer bal- cony parapet and arranged to be heated by the solar heat radiation that penetrates the outer balcony parapet,
the outer and inner balcony parapets defining between them a substantially vertical air gap, a fan arrangement, which is adapted to force air of the glazed balcony through the air gap from the lower part thereof to the upper part thereof for heating of said air,
and inner outlets arranged in the upper part of the air gap, through which outlets the heated air is allowed to flow out into the glazed balcony before being supplied to the room as supply air.
The inner outlets are closable.
In a preferred embodiment of the invention, closable, outer outlets are arranged in the upper part of the air gap and adapted, in an open state, to divert the air forced through the air gap to the outside of the glazed balcony. This diversion is used in particular in the summer and is achieved with the inner outlets closed and the outer outlets open.
Advantageously, the heat-absorbing, inner parapet is made of heat- absorbing glass. It can also be hollow and have an inner chamber which con- tains a heat-absorbing liquid or gas.
Advantageously, the fan arrangement is operated by means of solar panels.
Brief Description of the Drawings
Fig. 1 is a schematic view in vertical section of a glazed balcony provided with a device according to the invention.
Fig. 2 is an enlarged view in vertical section of the device according to the invention, the device being illustrated in a first setting position.
Fig. 3 corresponds to Fig. 2 but shows the device in a second setting position.
Description of a Preferred Embodiment
The glazed balcony 1 shown in Fig. 1 has a horizontal balcony slab 2 and, located directly above, a horizontal roof slab 3, which here forms the balcony slab of an upper balcony. Correspondingly, the balcony slab 2 forms the roof slab of a lower balcony. The two slabs 2 and 3 are mounted in conventional manner on the wall 4 of a building. At its front side the balcony 1 has an outer parapet 5 which is permeable to the heat radiation of the sun and formed of a plurality of substantially vertical glass panels arranged side by side. In the embodiment shown, the balcony 1 also has, at its front side, four mutually horizontally displaceable glass panes 6. The glass panels of the outer parapet 5 and the glass panes 6 are mounted in a frame structure.
The frame structure has an upper horizontal sectional element 7, a lower horizontal sectional element 8, an intermediate horizontal sectional element 9 and two vertical sectional elements (not shown), the horizontal sec- tional elements 7-9 extending between said vertical sectional elements. The outer parapet 5 is mounted between the lower sectional element 8 and the intermediate sectional element 9. The glass panes 6 are mounted between the upper sectional element 7 and the intermediate sectional element 9 and are mutually displaceable in per se known manner. The horizontal sectional elements 7-9 and the vertical sectional elements are suitably made of aluminium.
A room 10 is located inside the building wall 4 opposite the glazed balcony 1. The room 10 and the balcony 1 communicate via a ventilating opening 11 which is formed in the wall 4 and through which supply air is supplied to the room 10 from the balcony 1 , as indicated by the arrow P4 in Fig. 1.
An inner parapet 12 is arranged inside the outer parapet 5. The inner parapet 12 is formed of a plurality of substantially vertical panels arranged side by side and adapted to be heated by the solar heat radiation that penetrates the outer parapet 5. The panels of the inner parapet 12 are therefore advantageously black in colour and suitably consist of black panels made of heat-absorbing glass. The inner parapet 12 may also be hollow and have an inner chamber which contains a heat-absorbing liquid or gas.
The outer and inner balcony parapets 5 and 12 define between them a substantially vertical air gap 13. This air gap 13 is closed at the bottom by means of a horizontal sectional element 14, which is preferably made of aluminium and has inlets 15 distributed along its length. Each inlet 15 houses a fan 16, which is operated by means of a solar panel 17 and adapted, as indicated by the arrows P2 in Figs 2 and 3, to force air present in the glazed bal- cony 1 through the air gap 13 from the lower part thereof (inlets 15) to the upper part thereof for heating of said air.
The air gap 13 is closed at the top by means of a horizontal sectional element 18, which forms part of the intermediate horizontal sectional element 9 and has inner outlets 19 which are distributed along its length and open onto the glazed balcony 1 , and outer outlets 20 which open onto the outside of the glazed balcony 1. The outlets 9 and 20 are closable by means of valves in the form of slide dampers 21 and 22, respectively. Fig. 2 shows an inner outlet 19 in the open position and the corresponding outer outlet 20 in the closed position, whereas in Fig. 3 said inner outlet 19 is in the closed position and the corresponding outer outlet 20 is in the open position.
The inner parapet 12 is mounted between the horizontal sectional elements 14 and 18.
The device described above works in the following manner.
The air of the glazed balcony 1 is circulated in the direction indicated by the arrows P1 , P2, P3 and P4 shown in Fig. 1 , when the inner outlets 19 are open and the outer outlets 20 are closed (Fig. 2), which is the state that is used when the veranda formed by the glazed balcony 1 is to be heated and heated supply air (arrow P4) is to be supplied to the room 10. The cold air near the balcony slab 2 is sucked into the inlets 5 by the fan arrangement formed by the fans 16 and is forced by said arrangement in the direction indicated by the arrows P2 up through the air gap 13, inside which the air is heated by the inner parapet 12, which has been heated by the solar heat radiation. The heated air flows via the inner outlets 19 out into the glazed bal- cony 1 (arrows P3) before being supplied, via the opening 11 , to the room 10 as supply air (arrow P4).
In the case where the veranda is not to be heated and no heated air is to be supplied to the room 10, for example in the summer, the state of the device is changed to the one illustrated in Fig. 3, i.e. the state in which the inner outlets 19 are closed and the outer outlets 20 are open, the heated air being diverted to the outside of the glazed balcony 1 , as indicated by the arrows P5 in Fig. 3.
