Description

[Detailed description of the invention] This invention relates to a heat exchange ventilation device used for air conditioning and ventilation, which simultaneously exhausts polluted indoor air and supplies fresh outdoor air into the room through a heat exchanger. It is.

A heat exchange ventilation device, well known as an air conditioning ventilation fan, ventilates a room while suppressing heat loss. Therefore, the configuration is more complicated than that of a normal ventilation fan or ventilation device, and the main components include a heat exchanger and a blower, making the whole device large. In the conventional model, the heat exchanger and two blowers are all assembled into the ventilation main body, so if the ventilation main body is installed indoors, the ventilation main body of the room will occupy a large amount of space, and the condition of the room will be affected. There are many things. These problems have been addressed by locating the ventilation body outside, but there are also problems with ventilation bodies that protrude significantly outdoors.

It is an object of the present invention to provide a heat exchange ventilation system that can solve the above-mentioned conventional problems, occupies a small space indoors or outdoors, and does not disrupt the cohesion of the room.

Next, the configuration of the present invention will be specifically explained based on an embodiment shown in the drawings.

The heat exchange ventilation system as an application example of the present invention shown in the drawings includes a wall W serving as a partition wall that partitions a ventilation main body 1 incorporating the main components of the ventilation function into the inside and outside of the room.
It is attached to the outside of the room, and the room is ventilated by the communication cylinder 2 provided through the wall W. The main components of the ventilation function are an exhaust blower 3 for exhausting room air to the outside and a supply air blower 4 for supplying outside air into the room. That is, the ventilation main body 1 is formed with two independent passages, an exhaust passage _S1 and an air supply passage _S2 , each of which is individually provided with an exhaust blower 3 and a supply air blower 4. There is. The outlet end of the exhaust passage S ₁ is formed at the upper front surface of the ventilation main body 1 facing the discharge port of the exhaust blower 3, and the inlet end thereof is formed at the center of the back surface of the ventilation main body 1. In addition, the outlet end of the air supply passage S ₂ is formed at the center of the back of the ventilation main body 1, and the inlet end is formed in the ventilation main body 1 facing the suction port of the air supply blower 4.
is formed on the bottom and sides of the The inlet end of the exhaust passage S ₁ and the outlet end of the air supply passage S ₂ are arranged vertically adjacent to each other, and a connection port 5 is provided on the back side of the ventilation main body 1.
is formed. One end of a cylindrical or rectangular communication cylinder 2 provided through the wall W is connected to this connection port 5. The communication cylinder 2 is equipped with a prismatic heat exchanger 6 which has an air-to-air exchange function for heat and moisture, which are the main components of heat exchange, and is used to divide the inside of the communication cylinder 2 into air supply and exhaust air. It is inserted in an internal state so as to partition it as a ventilation passage. This heat exchanger 6 is equipped with two independent passageways _S3 that have entrances and exits opening at both ends of the communication cylinder 2, and is connected to the connection port 5 of the ventilation body 1 by connecting the communication cylinder 2 and the connection port 5 of the ventilation main body 1. Thus, each passage _S3 is individually connected to the inlet end of the exhaust passage _S1 or the outlet end of the air supply passage _S2 . A simple box-shaped indoor box 7 having a separate exhaust chamber _S4 and an air supply chamber _S5 is connected to the indoor opening end of the communication cylinder 2. The exhaust chamber S ₄ of the indoor box 7 has an intake port 8 opened indoors,
One passage S ₃ of the heat exchanger 6 connected to the exhaust passage S ₁
will be contacted. Further, the air supply chamber _S5 has an air outlet 9 opened indoors, and is connected to the other passage _S3 of the heat exchanger ₆ , which is connected to the air supply passage S2. In addition, when the connecting cylinder 2 is made into a cylinder, a square prismatic heat exchanger 6 is inserted in an inscribed state as shown in FIG. In this case, as shown in FIG. 4, the rectangular prism-shaped heat exchanger 6 is inserted into the connecting cylinder 2 at an angle of 90 degrees.

Therefore, the exhaust passage S ₁ and the air supply passage S ₂ are independent in the entire route, and intersect within the communication cylinder 2, allowing ventilation of the room while exchanging heat and moisture.
In other words, air conditioning and ventilation can be realized.

Since the ventilation main body 1 is the largest structure in this device, it is more convenient to install it outside the room because it will not disrupt the unity of the room. It is considerably smaller than the conventional model. Therefore, even if the ventilation main body 1 is installed indoors and the previous indoor box 7 is installed outdoors as another aspect of the present invention, the space occupied by the ventilation main body 1 in the room is smaller than before, and the condition of the room is not so great. It has not collapsed, and the air conditioning and ventilation function is the same as the previous example, so there are no problems.

As is clear from the above description of the embodiments, the heat exchange ventilation system of the present invention is designed to have a heat exchanger installed in the ventilation body, which forms the exhaust air flow and the supply air flow, and is the main body of ventilation. Since the ventilation body installed indoors or outdoors does not include a heat exchanger, the ventilation body can be made smaller, so the space occupied by the equipment in the room can be reduced. It has the advantage that it hardly disrupts the condition of the room.
