It is more preferable to adjust the first and second dampers 22 and 31 such that the first damper 22 is opened and the second damper 31 is sealed in winter.

In particular, the control unit 70, the input button unit 71, the ON / OFF (OFF) switch 72 and the display window 73 is preferably formed, in this case, the bathroom exhaust fan 23 Is preferably driven by a power supply (not shown) provided in the bathroom, but in winter, the controller 70 controls the bathroom exhaust fan 23 to be driven by sensing the outside temperature of the temperature detector 80. It is okay.

As a result, the controller 70 is set to the initial state by the ON / OFF switch 72, the appropriate button CO2 indoors by the input button 71 (CO2) The air supply fan 12 and the first and second dampers 22 and 31 and the bathroom exhaust fan 23 are driven by setting a concentration and an appropriate temperature outside air in winter.

That is, when the outside air proper reference temperature of the winter season is set to 5 degrees or less than 5 degrees below the image in the control unit 70, the temperature detector 80 detects the outside temperature and sends a signal to the control unit 70. The control unit 70 controls the first damper 22 and the second damper 31 according to the outside temperature to seal the natural exhaust unit 30 in winter to drive the bathroom exhaust fan 23. Contaminated air in the room is discharged to the outside through the mechanical exhaust unit 20, and the mechanical exhaust pipe 20 is sealed in the intermediate period (spring, summer, autumn) to indoor through the natural exhaust pipe (30). Polluted air will be discharged to the outside.

At this time, in the intermediate period (spring, summer, autumn), the bathroom exhaust fan 23 is driven by a power supply unit provided in the bathroom, and the bathroom ventilation is made separately from the indoor ventilation, and in winter, the control unit 70 or the bathroom The bathroom exhaust fan 23 is driven by the provided power supply device to simultaneously perform indoor ventilation and bathroom ventilation.

On the other hand, the first and second dampers (22, 31) is formed with a blocking plate therein, it is preferable that the block is formed of a motor damper that is opened and closed by the driving of the motor.

Due to this, the hybrid ventilation device (1) which combines mechanical ventilation and natural ventilation of a multi-family house according to the seasonal outdoor air temperature and indoor pollution concentration changes in the mid-term (spring, summer, autumn) is the outside of the air polluted indoors by natural ventilation. In the winter, the indoor air is discharged to the outside by mechanical ventilation.

As mentioned above, the reason why indoor polluted air is naturally ventilated during the middle period (spring, summer, autumn) and mechanical ventilation during the winter is because the air inside the building is cold during the middle period. This is because the polluted air may be naturally ventilated, and thus, power consumption may be reduced by blocking unnecessary driving of the bathroom exhaust fan 23 configured in the mechanical exhaust unit 20.

On the contrary, in winter, the interior of the building is warm and the exterior of the building is cold, so the pressure on the ground is low inside the building, so air entering the building on the ground due to this pressure difference enters the building, and thus, the natural exhaust part 30 is configured. After the 2 dampers 31 are sealed, the indoor polluted air drives the bathroom exhaust fan 23 to mechanically ventilate, thereby minimizing heat loss in the heating room due to inflow of external air. will be.

In particular, the second grade pipe 13 is buried in the indoor floor and installed so as to pass through the lower portion of the heating pipe 40, even if the cold air from the outside during the indoor ventilation in the winter to the waste heat of the heating pipe 40 The cold air is heat-exchanged by the outside to heat up and the external cold air can be supplied to the heating temperature of the room.

In addition, in summer, even if the outside hot air is introduced, the outside hot air is heat-exchanged by the cold air of the indoor floor surface, and the outside hot air can be supplied to the indoor cooling temperature as it becomes cold.

This can solve the problem that the indoor temperature is lowered due to the inflow of cold air during the indoor ventilation in winter, and the indoor temperature is increased due to the inflow of hot air in the summer, which is caused by the inflow of external air. By maintaining the room temperature without heat loss it is possible to reduce the power consumption due to unnecessary use of air conditioning and heating.
