Abstract

PURPOSE:To make construction work easy and make possible installation in a narrow area available in a wall, by giving dimensionally a long form to a ventilation apparatus and mounting a built-in fire damper each on outdoor side of the exhaust air passage for discharging air to the outside and the inlet air passage for intaking air into the inside. CONSTITUTION:Indoor air drawn through a plurality of suction ports 14 by an exhaust fan 3 is passed successibly through an exhaust chamber 12, a heat exchanger element 2, a fire-proof damper 10 to an exhaust ports 5 to be discharged to the outside therefrom. Outdoor air drawn through an intake port 7 by an intake fan 6 passes successibly through a fire-proof damper 11, the heat exchanger element 2 to a plurality of outlet ports 16 of an inlet chamber 13, flowing out therefrom into the room. The outdoor air, therefore, is heat- exchanged with the indoor air while passing through the heat exchanger element 2 countercurrently with the indoor air; as a result, air is supplied from the outlet ports 15 into the room under such condition that the temperature and humidity thereof is close to those of the air to be exhausted from the inside.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a total heat exchange type ventilation system that can simultaneously perform air supply and exhaust air.

[Conventional technology]

4 and 5 are an external view and a sectional view showing a conventional total heat exchange type ventilation device disclosed in, for example, Japanese Utility Model Application No. 54-75562, in which the ventilation device 1 is installed along a building wall W. In the exposed installation type, 2 is a heat exchange element, 3 is an exhaust fan that draws indoor air from an inlet 4 through the heat exchange element 2, and exhausts it to the outside through an exhaust port 5. This is a fan for supplying air through the replacement element 2 and into the room through the air outlet 8. Reference numeral 9 indicates a motor for driving both fans 3.6, and reference numerals 10 and 11 indicate fire dampers respectively disposed in air passages between the exhaust port 5 formed in the building wall W and the suction lower.

Next, the operation will be explained. Indoor air sucked through the suction port 4 by the exhaust fan 3 passes through the heat exchange element 2, the fire protection pump 1O, and is discharged to the outside from the exhaust port 5.

On the other hand, the outside air sucked in from the suction lower by the air supply fan 6 passes through the fire damper 11 and the heat exchange element 2.
The air is supplied into the room from the air outlet 8. For example, when the room is being cooled, the outside air sucked in from the suction lower is heat exchanged with the indoor exhaust gas by the heat exchange element 2, and the indoor temperature
The air is supplied into the room from the air outlet 8 in a state close to humidity.

[Problem that the invention seeks to solve]

Conventional total heat exchange type ventilation systems are configured as described above, so when installing a ventilation system, it is necessary to provide openings for air supply and exhaust in the building wall W, or to install a ventilation system in a building designated as a fire prevention zone. For exterior walls and buildings, fire dampers must be installed inside the building walls.

In addition, there are also problems with the installation location, such as the fact that horizontally oblong ventilation devices can only be installed in relatively wide spaces, such as at the bottom of windows.

This invention was made in order to solve the above-mentioned difficult problems, and it simplifies the installation work by incorporating a fire damper into the ventilation system, and also makes it possible to embed it in the wall or incorporate it into the wall. The purpose of the present invention is to obtain a total heat exchange type ventilation device that is vertically long and can be installed on a narrow wall.

[Failure to solve the problem]

The total heat exchange type ventilation device according to the present invention has a vertically elongated ventilation device, and has built-in fire dampers on the outdoor sides of the exhaust passage for exhausting air from indoors to the outdoors and the air supply passage for sucking air into the room from the outdoors. It is something.

[Effect]

The total heat exchange type ventilation system of this invention has a fire damper built into the air passage of the ventilation system, so there is no need for construction work such as installing a fire damper on the building wall as in the past. It can be embedded or built into a wall.

[Embodiments of the invention]

An embodiment of the present invention will be explained below with reference to the drawings.

Figures 1 (a) and (b) show a side view and a front view of the total heat exchange type ventilation system, and Figure 2 shows a side sectional view of the installed state. The heat exchange elements 12 and 13 are an exhaust chamber and an air supply chamber respectively provided on the upper part of the heat exchange element 2.Both chambers 11.12
An exhaust inlet 14 and an air supply outlet 1 are provided on the front and side surfaces of the
5 is set. Note that an exhaust inlet 14 and an air supply outlet 15 can be attached to the upper surfaces of both chambers 11 and 12, respectively (1), and can be closed with a panel when not in use. 3 is an exhaust fan, and the room air sucked in from the suction port 14 by this fan 3 is transferred to the chamber 12.
It passes through the heat exchange element 2 and is discharged to the outside through the exhaust port 5. Reference numeral 6 denotes an air supply fan, and the outdoor air sucked from the suction lower by this 7 un 6 passes through the heat exchange element 2, passes through the air supply chamber 12t, and is supplied into the room from the outlet 15. Reference numeral 9 denotes a motor that drives the upper G pin fans 3 and 6; 10 and 11 are fire dampers built into the exhaust port 5 and the air passage of the suction lower; 16, a ventilation system l is connected to the building wall W;
, the root is for installation.

In the total heat exchange type ventilation system of the present invention configured as described above, the indoor air sucked from the plurality of suction ports 14 by the exhaust fan 3 is passed through the exhaust chamber 11 and the heat exchange element 2, and the fire prevention damper lO It is then discharged to the outside of the room through the exhaust port 5. On the other hand, the outdoor air sucked from the suction lower by the air supply fan 6 passes through the fire damper 11, passes through the 2ft heat exchange element, and is passed through the plurality of air outlets 15 of the air supply chamber 12.
It is supplied indoors. Therefore, the outdoor air and the indoor air exchange heat when passing through the heat exchange element 2, and the indoor air is supplied into the room from the outlet 15 under conditions close to the temperature and humidity of the indoor air to be exhausted. By the way, fire damper to,
When a fire occurs outdoors or indoors, the tt detects the temperature and automatically shuts off the air passage to prevent the fire from passing through, and it penetrates buildings and walls as required by law. required in some cases.

FIG. 3 shows an installation example of the above-mentioned ventilation system, in which a suction grill 18 embedded in the wall is connected to the exhaust air inlet 14 through a duct 17, and an air outlet embedded in the wall is connected to the air supply outlet 15. A grill 19t is attached.In this way, the ventilation system can be installed in a narrow space on the wall of a building without damaging the interior of the room.

In addition, the ventilation system can be embedded or built into the wall W, and as shown in Figure 2, the wall W is assembled in a factory, transported to the site, and then installed in the wall (16). It is also possible to install the ventilation system in the wall.

〔Effect of the invention〕

As explained above, according to the present invention, the ventilation device is vertically elongated, and fire dampers are built in on the outdoor sides of the exhaust passage that discharges air from the room to the outdoors and the air supply passage that sucks the air into the room from the outdoors. This eliminates the need for construction work such as installing a fire damper on a building wall as in the past, making the construction work easy and inexpensive. In addition, it can be embedded or incorporated into a building wall, and since it is vertically long, it can be installed in a narrow wall.
