Description

Air purification circulator

The present invention relates to an air cleaning circulator.

In general, a ventilation device capable of ventilating indoor air without opening a window is installed in a building.

Such a ventilation device is composed of a duct that connects indoors and outdoors, and a blower that discharges indoor air to the outside or introduces outside air into the room through the duct. Since such a ventilation device directly inflows outside air into the room, it lowers the cooling and heating efficiency of the building.

In order to solve this problem, registered patent (10-0690987) discloses an air cleaning system including a heat exchanger for exchanging external air and indoor air. The heat exchanger heat-exchanges the external air flowing into the room and the indoor air discharged to the outside, so that the temperature of the external air and the indoor air can be matched to some extent.

However, in the heat exchanger, external air and indoor air simply intersect, so if the temperature difference between indoors and outdoors is large, such as in summer or winter, heat exchange efficiency inevitably decreases. In this case, even if a heat exchanger is used, it is difficult to prevent the building's cooling and heating efficiency from falling.

In order to solve this problem, registered patent (10-1105995) discloses a heat recovery ventilation device including a bypass flow path. Through the bypass passage, a part of the indoor air can be guided to the heat exchanger together with the outside air, so that heat exchange efficiency can be maintained even when the temperature difference between indoors and outdoors is large, such as in summer or winter.

However, in recent years, due to inconvenient installation and replacement of the heat exchanger, there is an increasing demand for an air-cleaning ventilator without the heat exchanger itself.

As such, there is a slim type air cleaning ventilation device disclosed in the registered patent (10-1811179) as the air cleaning ventilation device without a heat exchanger. However, in such a slim air cleaning ventilator, if the bypass damper is blocked, indoor air is bound to stagnate in the case, and if the bypass damper is open, indoor air is mixed with outside air and enters the room again. It is difficult to discharge to the outside. For this reason, it is difficult to implement a ventilation mode in which all indoor air is discharged to the outside, and it is difficult to implement various other modes.
