Abstract

PURPOSE:To enable a heat exchange type ventilating device to be mounted to the interior of a ceiling or an arbitrary place on a wall and to enable ventilation of a plurality of rooms without damaging indoor appearance, by a method wherein a blower for air feed, a blower for exhaust, and a heat exchanger are contained in their respective boxes, and the boxes are connected to each other through an air passage. CONSTITUTION:A feed air 7 fed from the exterior of a room to the interior of a room is sucked through rotation of a blower 4 for air feed, and is supplied to the room from an indoor air feed grill 11 through a damper box 16 for air feed, an air passage 18, a blower box 14 for air feed, an air passage 18, and a heat exchanger 13. An exhaust air 8, exhausted from the interior of the room to the exterior of the room, is sucked from an indoor exhaust grill 12 through rotation of a blower 5 for exhaust, and is exhausted to the exterior of the room through a heat exchanger box 13, the air passage 18, a blower box 15 for exhaust, the air passage 18, and a damper box 17 for exhaust. Since the box bodies 13-17 are formed in a small size independently from each other and are connected to each other through the air passages 18, the box bodies can be installed even in a relatively small space, and a distance therebetween can be easily changed through change of the length of the air passage 18.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a ventilation system that performs air supply and exhaust through a heat exchanger.

[Conventional technology]

Figures 7 and 8 are views of the conventional heat exchange type ventilation system shown in, for example, Japanese Utility Model Publication No. 54-42125, which is installed exposed on the ceiling; Figure 7 is a perspective view of the room, and Figure 8 is FIG.

In the figure, (IA) is the outer wall of the building, (IB) is the inner wall of the building,
(1c) is the ceiling, (2) is the outer box installed exposed along the ceiling (1C), and (3) is the heat exchanger housed inside the outer box (2), which communicates with many corrugated plates. The outer box (2 ) and 45
It is installed at an angle. (4) is a supply air blower installed on the inflow side of the blown air of the heat exchanger (3), (5) is an exhaust blower installed on the outflow side of exhaust air, (
6 is an air supply/exhaust box that is installed through the building wall and is equipped with a damper to block the fire/airflow path and communicates with the outer box (2); (7) is an air supply; and (8) is an exhaust.

The conventional heat exchange type ventilation system is configured as described above, and the supply air (7) supplied from the outdoors to the room is supplied to the supply air blower (4).
) is sucked into the air supply and exhaust box (6).

9. In the outer box (2). It passes through the heat exchanger (3) and is blown into the room. Also, exhaust gas discharged from indoors to outdoors (8)
is sucked into the outer box (2) by the rotation of the exhaust blower (5), passes through the heat exchanger (3), and is blown out from the air supply/exhaust box (6) to the outside. When the room is being cooled, the supply air (1) supplied from outside is heat exchanged with the exhaust air (8) discharged from the room in the heat exchanger (3), until the temperature and humidity are close to the indoor temperature. It is cooled and dehumidified before being supplied indoors.

[Problem that the invention seeks to solve]

In the conventional heat exchange type ventilation system as mentioned above, it is necessary to provide a penetration part in the wall for air supply and exhaust, and a fire damper must be installed inside the wall for external walls and buildings designated as fire prevention zones. The problem is that it does not. Additionally, since they are installed exposed on the ceiling, they impair the aesthetics of interior decoration, and there is also the problem that one unit needs to be installed in each room.

This invention was made to solve the above problems, and can be installed anywhere inside the ceiling or on the wall.

To provide a heat exchange type ventilation device which can ventilate a plurality of rooms without spoiling the beauty of the room.

[Means for solving problems]

The heat exchange type ventilation device according to the present invention has a supply air blower, an exhaust air blower, and a heat exchanger housed in independent boxes, and these boxes are connected by an air path.

[Effect]

In this invention, each functional component is housed in a separate box, so the size of the two boxes is reduced.

In addition, by changing the air path, the installation position of the υ box is not restricted, and air supply and exhaust can be freely applied to multiple rooms.

〔Example〕

Figures 1 to 4 are diagrams showing one embodiment of the present invention.
The figure is a plan view, FIG. 2 is a front view, FIG. 3 is an interior perspective view, and FIG. 4 is a vertical sectional view, (IA) to (ic).

(2) to (51, +7+, +81) are similar to those of the conventional device described above.

In the figure, α[ is the window frame, αυ is the inner wall at the top of the window frame (11
B) is an indoor air supply grill that blows out the supply air (7) into the room, 03 is an indoor exhaust grill that also sucks exhaust air (8) from the room, and α3 is a heat exchanger that houses the heat exchanger (3). The box, αY, is a supply air blower box in which the supply air blower (4) is stored, 歺9 is the exhaust blower box, in which the exhaust blower (5) is stored, and αe is the fire prevention damper (not shown). The air supply damper box, a71a, is also an exhaust damper box,
+13-(IT) each has a height A of 350 mm or less,
The depth B is formed to be 200 mm or less, and it is provided inside the outer wall (1 person) and the inner wall (1B), is placed on the upper part of the window frame αI, and is connected to each other by an air channel α barrel such as a duct.

In the heat conversion type ventilation system configured as above,
The supply air (7) supplied from the outdoors to the room is sucked in by the rotation of the supply air blower (4), and is sent to the supply air damper box αQ→
The air passes through the air path α seconds → supply air blower box 04 → air path +18 → heat exchanger box α3, and is blown into the room from the indoor air supply grill αυ. In addition, the exhaust gas (8) discharged from indoors to outdoors is
Depending on the rotation of the exhaust blower (5), indoor exhaust grill 02
It is sucked in from the heat exchanger box 0 → air path αυ → exhaust blower box αω → air path α♂ → exhaust damper box QD and is blown out to the outside of the room.

Each of the boxes αJ to Q71 is independently formed into a small size and is connected with a wind path brocade, so it can be installed even in a relatively small space. It can be easily changed by changing.

The air supply damper box and exhaust damper box 07+ are designed to prevent the spread of fire by sensing the temperature and automatically blocking the air passage when a fire occurs outdoors or indoors.
It is required to be installed when penetrating buildings and external walls as stipulated by law. but,
It can be easily removed if it is not subject to legal restrictions.

There is an example in which one ventilator is installed in one room in the ones shown in Figures 1 to 4, while one ventilation device is shared between two rooms in the ones shown in Figures 5 and 6. This is what is shown.

In other words, it is applied when one span from pillar to pillar or beam to shi of a building is divided into two rooms by 9 partitions 11. Indoor air supply grill (ILA), (HB)
and indoor exhaust grilles (12A) and (12B), which are connected to the heat exchanger box 03 by a path αe. In this way, it becomes possible to ventilate two rooms with one ventilation device.

〔Effect of the invention〕

As explained above, in this invention, the air blower, exhaust blower, and heat exchanger are housed in independent boxes,
Since these boxes were connected to the air passage, the inside of the ceiling -?
Can be installed anywhere on the wall.

It has the effect of ventilating multiple rooms without compromising the aesthetics of the room.
