Abstract

PURPOSE:To simplify the installation work and make possible a built-in inside wall or assembling of the apparatus, by providing an intake chamber and an exhaust chamber respectively on the right and left sides of the apparatus and placing a built-in fire-proof damper in each of said chambers. CONSTITUTION:Indoor air drawn by an exhaust fan 3 through a suction port 4 is passed through a heat-exchanger element 2, a fire-proof damper 10 in an exhaust chamber 13 and discharged from an outlet port 5 to the outside, while outdoor air drawn by an intake fan 6 through an inlet port 7 is passed through a fire-proof damper 11 in an intake chamber 12, the heat-exchanger element 2 and supplied into the room through a blow-off port 8. Accordingly, when the outdoor air and indoor air passes through the full heat-exchanging element 2, heat transfer occurs between both of said airs; 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. As the intake and exhaust chamber each are provided with a fire-proof damper in such a manner as stated above, construction work to install a fire-proof damper in the wall of a building is unnecessitated.

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]

Figures 4 and 5 show an external view and a sectional view of a conventional total heat exchange type ventilation system disclosed in, for example, Japanese Utility Model Application Publication No. 54-75562. 2 is a total heat exchange element; 3 is an exhaust fan that draws indoor air through the total heat exchange element 2 from an inlet 4 and exhausts it to the outside through an exhaust port 5; 6 is an outdoor fan; This is an air supply fan that draws air from the lower part through the total heat exchange element 2 and supplies it into the room through the air outlet 8. 9 is a motor that drives both fans 3 and 6, and 10 and 11 are building walls W. Fire prevention dampers are respectively disposed in the air passage of the exhaust port 5 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, passes through the fire damper IO 9, 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, the heat exchange element 2t, and 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 by the heat exchange element 2, and is supplied into the room from the air outlet 8 in a state close to the temperature and humidity of the room.

[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 external walls and buildings, fire dampers must be installed inside the building walls.

There were problems with construction.

This invention has been made to solve the above-mentioned problems, and aims to provide a completely wedge-shaped ventilation device that is easy to install and can be embedded or built into a wall.

[Means for Solving the Problems] The total heat exchange type ventilation device according to the present invention has an air supply chamber and an exhaust chamber on the left and right sides of the device, and a fire prevention damper is built into each chamber. .

[Effect]

The total heat exchange type ventilation system according to the present invention has a fire damper built into 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 becomes possible to embed the ventilation system in the wall or assemble it.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings. 1st
Figures (a) and (b) show a rear view and a side view of the total heat exchange type ventilation device, in which l is the ventilation device, and 12 and 13 are the air supply chambers provided on the left and right sides of the ventilation device l, respectively. and an exhaust chamber, both chambers 12.13
Each has a 10° fire damper built-in. Figures 2 and 3 are a cross-sectional view and an external view showing the ventilation system #l installed in a built-in manner on the building wall W1, where 69.2 is a total heat exchange element, 3 is a total heat exchange element, and 3 is a total heat exchange element that draws room air from the suction port 4. Heat exchange element 2
1. An exhaust fan that exhausts air from the exhaust chamber 13 through the fire damper 11 to the outside of the room through the exhaust port 5;
Reference numeral 6 indicates that outdoor air is sucked from the lower part through the total heat exchange element 2 via the fire damper lO and the air supply chamber 12, and the air outlet 8
This is a fan that supplies air into the room. Reference numeral 9 indicates both the fans 3, 6f: a driving motor, and 14 indicates bolts for installing the ventilation system 1 on the wall of the building.

In the total heat exchange type ventilation system of the present invention configured as described above, the indoor air sucked from the suction port 4 by the exhaust fan 3 is passed through the heat exchange element 2, and the fire prevention damper 1ot-a in the exhaust chamber 13 It is discharged outside from the exhaust port 5. -10,000, outside air sucked from the suction lower by the air supply fan 6 is sent to the fire prevention damper 1it in the air supply chamber 12-
The air then passes through the heat exchange element 2 and is supplied into the room from the air outlet 8.

Therefore, the outdoor air and the indoor air exchange heat when passing through the total heat exchange element 2, and the indoor air is supplied into the room from the outlet 8 under conditions close to the temperature and humidity of the indoor air used for exhaust.

Incidentally, the air supply chamber 12 and the exhaust chamber 13
The fire damper 10.11 installed in the chamber is designed to detect the temperature of a fire and automatically shut off the chamber to prevent the passage of fire in the event of a fire occurring outdoors or indoors. Required when penetrating buildings and walls.

The ventilation system can be embedded in the wall W1 or built into the building wall, and as shown in Figure 2, the ventilation system can be installed in the wall W1.
are assembled in a factory etc. and delivered to the site, and then the gelt 14
It is also possible to install the ventilation device on the wall W.

〔Effect of the invention〕

As explained above, according to the present invention, a fire damper is provided in each of the air supply chamber and the exhaust chamber of the ventilation system, so that installation work such as installing a fire damper on a building wall as in the conventional case is not required. is no longer necessary,
This makes construction work easy and inexpensive. Furthermore, it is easy to embed or integrate into the wall of a building, and it also has the advantage of good appearance because it does not protrude into the room.
