The present invention relates to a ventilation system, and in detail, the air supply space is separated into a room and a kitchen (including a living room), and when the hood of the kitchen is operated, the integrated ventilation using a heat exchanger to supply air only to the kitchen to perform ventilation. It's about the system.

In general, high-functional high-rise apartments, which are being constructed recently, have windows (curtain wall) to be sealed in terms of energy conservation, and such high-rise apartments inevitably need to introduce a large amount of fresh air in response to the demand for comfort. Therefore, the indoor ventilation problem is becoming more serious.

1 is a cross-sectional view showing a typical building.

As shown in FIG. 1, in a typical building, a plurality of hoods 2 and an exhaust port 3 are connected to the kitchen exhaust shaft 4 in a kitchen countertop 1, a bathroom, a ceiling, and the like, and are contaminated indoors. Air is discharged through the hood 2 and the exhaust port 3 to the kitchen exhaust shaft 4.

In addition, the interior of the building is equipped with a variety of air conditioning and heating, the room to perform the cooling and heating, the air supply vent (5) is provided on the outer wall naturally, the hood (2) and the exhaust port (3) as described above In place of the polluted air discharged through the) through the air supply (5) fresh air is introduced into the room.

However, when the exhaust hood and the exhaust fan are operated at the same time in order to discharge the polluted air in the room as described above, the general building as described above is constructed by the curtain wall method, so that the interior is sealed, and thus naturally ventilated to the outer wall. Even if the air inlet is installed, only the air is exhausted from the enclosed space, and the air is not supplied to the room smoothly. As a result, the negative pressure is generated in the room, thereby greatly reducing the efficiency of the hood and the exhaust fan. At the same time, the ventilation of the room is also not made smoothly, as well as the overall ventilation effect, there was a disadvantage that the indoor environment is deteriorated.

In addition, the natural air supply is installed to solve the problem that occurs when only the indoor air is exhausted as described above, but as outdoor air is directly distributed through the natural air supply, cold outside air in the heating room Direct inflow or direct inflow of hot and humid outside air into the air-conditioned room destroys the indoor air environment and heat environment, resulting in large energy loss, and thus, the overall cooling and heating efficiency of the building is greatly reduced. .

In order to solve the above problems, Utility Model Registration No. 0406146 (Registration date January 09, 2006, name: indoor ventilation using a heat exchanger) has been developed.

One end of each of the air supply duct 30 and the exhaust duct 40 is connected to the heat exchanger 10, and the other ends of the air supply duct 30 and the exhaust duct 40 are respectively installed on the ceiling of the room. It is connected to the ventilation opening (20).

However, the indoor ventilation device using the conventional heat exchanger has a problem that the air supply and exhaust is not made smoothly when the indoor pollution is high when using the kitchen because the air supply to the entire space is made at the same time.

In addition, the conventional ventilation device using the conventional heat exchanger has another problem that the operating noise of the heat exchanger is transmitted through the exhaust duct.

The present invention is to solve the above problems, separate the air supply space into the room and the kitchen (including the living room), and when the hood of the kitchen to supply air only to the kitchen to prevent the diffusion of pollutants and It is an object of the present invention to provide an integrated ventilation system using a heat exchanger for quick ventilation.
