Description

Ventilation device {Ventilation}

The present invention relates to a ventilation device capable of maintaining a constant air temperature in a building or purifying the indoor air using a total heat exchange unit. In particular, the contaminated indoor air is purified by a filter member inside the ventilation device and then purified. It relates to a ventilation device in which energy efficiency is improved by supplying indoor air to the room without using a total heat exchanger.

The indoor air in which we live is polluted by various factors, and ventilation that discharges contaminated indoor air to the outside and introduces outdoor air into the room is essential for a comfortable life.

In particular, in places where many people stay in a confined space, such as an office, it is necessary to ventilate from time to time. At this time, for general ventilation, there was a method of opening a window or using a ventilator.

However, when ventilation is performed by opening a window of a building, the cooling and heating efficiency of the building decreases, and in recent years, a ventilation device or air conditioning system capable of forcibly venting the air in the building due to extremely fine dust has been installed in the building.

In addition, as our residential spaces are becoming more and more high-rise today, the opening of windows is restricted due to problems such as stability and energy saving, noise, and security. Living spaces are becoming increasingly confidential or closed.

In accordance with these changes, almost all buildings today require a ventilation or air conditioning system that supplies fresh air from the outside and discharges the air to the outside. This ventilation system is a waste heat recovery type ventilation system equipped with a total heat exchanger. Is mainly used.

The waste heat recovery ventilator of this structure introduces outdoor air into the frame through an outdoor intake port, purifies it with a filter, and supplies it indoors through an indoor exhaust port. At the same time, indoor air is introduced into the frame through an indoor intake port and then outdoor. Exhaust to the outdoors through an exhaust port.

A total heat exchange unit is provided inside the frame of a general waste heat recovery ventilator, and its own heat energy (cold or warm) is transmitted through the total heat exchange unit before the indoor air introduced through the indoor intake port is discharged to the outside through the outdoor exhaust port. The outdoor air introduced through the outdoor intake port is also discharged through the indoor exhaust port after receiving the heat energy transferred to the total heat exchange unit while passing through the total heat exchange unit. At this time, the outdoor air and the indoor air are discharged by a blowing fan, respectively, and the operation of the blowing fan is controlled by a control box installed in the frame.

Republic of Korea Patent Registration No. 0690987 discloses that harmful components are easily discharged outdoors by ventilating indoor and outdoor air through a total heat exchange unit during a certain period of time when harmful components that cause sick house syndrome are detected after a new building is constructed, and after a certain period of time, harmful components are further released. When no abnormality is detected, an air cleaning system using a ventilation unit that can prevent heat loss by recirculating indoor air by purifying indoor air using a filter and an anion generator has been introduced.

In the above technology, when outdoor air passes through the total heat exchanger, energy efficiency sometimes decreases, so the technique of using a bypass duct was introduced.However, due to the complicated bypass duct, the ventilation system increases, manufacturing cost and maintenance cost. This excessive consumption problem occurred.
