In this way, When the air conditioner is operated, indoor air may become turbid or contaminated. Thus, the indoor air is ventilated by periodically ventilating the room by discharging the room air outward and introducing fresh outdoor air into the room.

On the other hand, in the case of a cattle breeding livestock such as cattle or pigs, the air inside the cattle can easily become turbid or contaminated by the carbon dioxide and livestock excretion caused by the breathing of the cattle, It is managed to ensure good ventilation.

The ventilation device installed to ventilate the room air as described above is generally divided into a forced ventilation system and a natural ventilation system according to an air circulation system. In the forced ventilation system, an air discharge piping communicating with outdoor is installed in a room, In this piping, a fan unit driven by a motor is installed to ventilate the room air through the piping. In this case, a plurality of fan units may be installed depending on the size of the indoor space. In this case, In addition, when the air is ventilated, there is a disadvantage that the energy consumption is large. Moreover, since air is forced to be circulated by the fan unit and air is discharged, a difference occurs in the amount of air supplied and exhausted, Or an excessive static pressure may be generated.

On the other hand, in the natural ventilation system, instead of installing a fan unit driven by a motor, an opening communicating with the outside of the building is installed in the building, and external air is introduced and extracted through the opening to circulate air in the room by natural convection. There is a disadvantage in that the ventilation performance is deteriorated due to the inadequate ventilation of the room air, and thus there is a possibility that the room temperature becomes low in the winter season or the indoor humidity becomes high in the rainy season have.

Therefore, it is required to develop a ventilation device that can save energy and have a good exhausting performance of air in a building with low energy consumption as in a natural ventilation system.

In response to the above-mentioned demand, the present applicant has developed an energy-saving type ventilator (Patent Publication No. 2013-0112584) with a power generation device and applied for a patent. A horizontal duct 100 installed on a side wall of the building and communicating with the inside of the building; A vertical duct 200 connected to the vertical end of the horizontal duct 100 and installed vertically; A fan unit 300 installed inside the horizontal duct 100; A generator (400) connected to the fan unit (300) and producing electrical energy by rotation of the fan unit (300); And a heating jacket 500 installed on the outer circumferential surface of the vertical duct 200 and filled with air to heat the vertical duct 200.

With this configuration, the ventilator is heated in the process of discharging indoor air through the horizontal duct 100 and the vertical duct 200, and the heated indoor air is discharged to the upper side faster by the convection phenomenon, The heating jacket 500 needs to be continuously heated by solar heat in order to heat the vertical duct 200. In a rain or cloudy weather, The jacket 500 is not heated sufficiently and the flow rate of the air discharged to the outside of the communication is low so that the generator can not be continuously driven and the electric energy can not be continuously generated. have.
