Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a ventilation apparatus having a high efficiency heat exchange structure,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation apparatus using a highly efficient heat exchange structure, and more particularly, to a ventilation apparatus employing a highly efficient heat exchange structure capable of efficiently saving cooling / .

In general, pigs, cows, chickens, and other breeding houses are ventilating fans for ventilating indoor air. Particularly, in a winter house or in a cold weather in a cold weather, a barn was installed in double and triple rooms using insulation to prevent heat loss.

In the feces of the livestock, ammonia hydrogen sulphide gas, odor and dust are generated, and it is forced out by the ventilating fan to the outside or the window is opened to ventilate by natural ventilation.

Specifically, in one embodiment, the housing has an air inlet near the entrance, and a ventilation fan is installed on the opposite wall surface or the ceiling through each room of the house to perform ventilation by forced convection.

However, this technique is a forced exhaust method using only a ventilation fan. Since the indoor air is not sufficiently supplied to the bottom surface of each room of the housing, indoor air is not properly supplied. There is a problem that the cold air is suddenly dropped to generate heat loss, and the cold air and the hot air in the room collide with each other to cause condensation.

In another embodiment, an air duct is provided on the upper part of the room throughout the room, so that the high-pressure discharge air is supplied from the air duct to the bottom surface of each room.

However, in order to discharge air at high pressure, the electric power had to be increased, and the noise caused the pigs to be stressed, which hindered the growth of pigs. Since the external cold air directly touches the livestock, there is a risk that the livestock may be subjected to thermal shock depending on the type of livestock, and scattering of the dust inside the house is easy, but the air circulation is not performed properly and adversely affects the physical health of the livestock Respectively.

In particular, in the case of pigs, it was possible to supply a certain amount of air if each of the money pouches was a sash, but it was not easy to ventilate the entire pouch due to the large number of pigs spreading over the money pouch line. And the ventilation efficiency of the whole pond was decreased when each pond of the pension company was partitioned by the cement wall.

Furthermore, since the above-mentioned barn is cooled in summer and heated in winter for a pleasant temperature inside the barn, the maintenance cost for keeping the room temperature suitable for the growth of livestock is large, which puts a heavy burden on the farm household economy.

In recent years, in order to solve such a problem, there has been developed a heat exchange ventilator which discharges indoor air to the outside, exchanges outdoor air with room air, and then introduces the indoor air into the room.

1, the ventilation system drives the outdoor air intake fan 30 and the indoor air exhaust fan 40 by a single drive motor 50. The outdoor air intake fan 30 and the indoor air exhaust fan 40 are driven by a single drive motor 50, So that indoor air and outdoor air are fed to the heat exchanger (60) side. At this time, outdoor air to be fed is heat exchanged through an orthogonal flow (cross flow).

However, the above-mentioned heat exchange ventilator is required to periodically remove foreign substances remaining in the heat exchanger when it is applied to housing where many foreign substances such as dust are generated. However, there is a problem that it is very difficult to clean the structure of the heat exchanger itself.

Korean Patent Publication No. 10-2014-0121917 (published Oct. 17, 2014) Korean Registered Patent No. 10-1437291 (Announced on September 3, 2014) Korean Patent Publication No. 10-2006-0019889 (published March 6, 2006)

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide an air conditioner which expands a passage through which indoor air is discharged to the outside and a passage through which outdoor air is sucked into the indoor space to increase the efficiency of energy recovery in air ventilation, The present invention is to provide a ventilation system using a highly efficient heat exchange structure that can easily clean foreign substances such as dust and the like.

In order to achieve the object of the present invention, in an embodiment of the present invention, a front end and a rear end of a rear end are opened, an exhaust passage connecting the front and rear surfaces is formed, A second housing formed to surround the front end front face of the first housing and having an air inlet port, and a second housing formed on the side of the front end of the first housing, A third housing formed so as to surround the first outer air outlet and formed with a second outer air outlet; and a plurality of second housing openings formed in the exhaust passage of the first housing so as to vertically divide the exhaust passage of the first housing, An outlet is formed on a side surface of the first outdoor unit and an outlet is formed on a side surface of a rear end facing the first outdoor unit outlet, Output to provide a ventilation apparatus for dressing the inside comprises a heat exchange unit which passage is to be formed.

The use of the ventilator according to the present invention maximizes the efficiency of energy recovery at the time of air ventilation because the section where the exhaust passage of the indoor air and the intake passage of the outdoor air are in contact with each other is expanded as compared with a general heat exchanger.

Further, the ventilator according to the present invention allows the user to confirm the entire section of the exhaust passage from the outside, and it is possible to easily grasp that foreign matter such as dust accumulates in the exhaust passage.

In addition, since the exhaust passage of the present invention has a straight line structure, it is possible to easily remove the foreign matter accumulated in the exhaust passage even if the exhaust passage is installed in a housing where many foreign substances such as dust are generated. Therefore, the ventilator according to the present invention can continuously remove the foreign matter accumulated on the exhaust passage even when the ventilator is used for a long time, so that the ventilation passage can be kept constant since the exhaust passage is not narrowed.
