Description

Ventilator with fan drive and heat exchanger separated

The present invention relates to an indoor air ventilator, and more particularly, a heat exchange part in which heat exchange is performed while the indoor air and external air intersect, an exhaust fan for discharging indoor air to the outside, and an intake fan for supplying external air to the room. The fan driving unit is installed, but the fan driving unit and the heat exchange unit are installed so that the fan driving unit is installed on the veranda, which is a boundary between indoors and outdoors, and the heat exchange unit is installed indoors to prevent condensation occurring in the heat exchange unit. At the same time, by eliminating the fan provided in the indoor filter box to remove the noise generating element of the room relates to a ventilator separated from the fan drive unit and the heat exchange unit for clean and quiet ventilation of the room more comfortably.

In general, the air in an enclosed space provided in the interior of the building increases or contaminates the contents of carbon dioxide over time due to the breathing or activity of the occupant, which greatly affects the inner activity of the occupant.

Therefore, in a space where many people stay, such as an officetel or a department store, the indoor polluted air should be frequently ventilated with fresh air outside. At this time, a commonly used ventilation device.

Most conventional ventilation apparatuses employ a method of forcibly discharging only indoor air to the outside using a single blower. However, when forced to discharge only indoor air by using one blower, the indoor air is discharged to the outside without filtration and the outdoor air is introduced without heat exchange through a door or window gap, thereby heating and cooling the room. The cost to spend was unnecessarily high.

In addition, sudden cold air and heat flows from the outside to the inside of the air due to a sudden temperature change, people in the interior feel unpleasant, especially when the indoor air is discharged only when the windows and doors are closed. Oxygen deficiency may occur due to blocking the inflow of fresh air from outside, and humidity control of indoor air is not achieved at all, but there is a problem that does not maintain a comfortable indoor environment even though a ventilation device is provided. .

In order to solve this conventional problem, when the indoor air is discharged to the outdoor, the heat exchange method of the ventilation system for the first heat exchange with the discharged indoor air and then supply the outdoor air has been proposed.

The above-described heat exchanger ventilation apparatus discharges indoor air to the outside and at the same time sucks the outdoor air and discharges it into the room, through the process of crossing the indoor air discharged to the outside and the outdoor air flowing into the room. By making the heat exchange with each other, the temperature of the outdoor air flowing into the room is controlled to bring it closer to the indoor air.

Thus, even if the indoor air to be ventilated by the outdoor air to lower the change in the room temperature, minimizing the increase in load required for cooling or heating.

Looking at the configuration of a conventional ventilator having a conventional general heat exchange method,

An air supply duct in which the outdoor air is guided to the inside of the hollow body is provided, and an exhaust duct intersecting the air supply duct at a predetermined position and the indoor air is guided to the outside is provided. A total heat exchanger is provided for exchanging outdoor air that is supplied at the point where the air supply duct and the exhaust duct intersect with the indoor air that is exhausted. At this time, the air supply duct and the exhaust duct are not interfered with each other by the partition wall partitioning the inside of the body up and down.

The conventional ventilation apparatus as described above is installed in the air supply fan and the exhaust fan in the air supply duct and the exhaust duct, and is driven to supply and discharge the outdoor air to the room and the indoor air to the outside, respectively. Since such a ventilator is usually installed in a balcony, which is a boundary between indoor and outdoor, condensation may occur in a heat exchange part where indoor hot air and outdoor cold air meet each other.

In addition, since the outdoor air is filtered by a prefilter attached to the front end of the heat exchanger and discharged into the room, the dust accumulated in the prefilter needs to be periodically cleaned or replaced. It is very difficult and cumbersome to open the veranda ceiling and clean or replace it. In particular, when the outdoor air is bad, the replacement or cleaning interval of the prefilter is shortened, which makes the maintenance more difficult.

On the other hand, Applicant has a patent application No. 10-2018-0045754 to clean the air introduced through the heat exchanger and the heat exchanger once the heat exchanger is installed so that the heat exchange is performed while the indoor air and the external air crosses the outside to be supplied to the interior Applied a ventilation device consisting of a filter box connected to the air supply passage.

The patent has a structure in which a fan for forcing air in and out is installed while the filter box is installed indoors as a ventilation device having a filter box. However, the conventional ventilator equipped with a filter box is a problem that the fan is installed inside the filter box provided in the room, the loud noise is generated by the operation of the fan when the indoor air ventilation (operation) to interfere with the pleasant environment in the room There is.
