Ductless exposed heat recovery ventilator {A Ventilator}

The present invention relates to a heat recovery ventilator for ventilating indoor air, and more particularly, is installed in an exposed type on the side wall of the room without a duct, the lower return chamber to which the indoor air flows, the indoor air and the outside air It consists of a heat exchanger unit is installed, the heat exchanger is installed so that the heat exchange occurs while crossing, and an upper air supply chamber for supplying the purified air into the room, the heat exchange unit is provided with an outside air supply pipe and the air discharge pipe, the outdoor air Ventilation mode where the air is ventilated directly by the air inside the room, the internal circulation mode where the outdoor air is completely blocked and the indoor air is purged through the electrothermal heat exchanger and resupply to the room, and the dust of the dust collecting filter installed in the heat exchanger. Ductless exposed heat recovery to clean the room while switching to filter elimination mode to remove It relates to a group unit.

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

Therefore, when a large number of people stay in a narrow space such as an office or a vehicle, 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 the indoor air by using a single blower, the cold air or heat in the room is discharged directly to the outside without going through a separate filtering device and the outdoor air is introduced without heat exchange through the door or window gap As a result, the cost of heating and cooling the room is 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 inside the interior feel unpleasant, especially when the indoor air is discharged only when the windows and doors are closed. Oxygen deficiency may be caused by the inflow of fresh air from outside, and the humidity control of the indoor air is not achieved at all, and there is a problem in that a pleasant indoor environment is not maintained even though a ventilation device is provided. .

In order to solve the conventional problems, when the indoor air is discharged to the outside, the heat exchanger ventilation apparatus for exchanging the indoor air discharged first and then supplying the outdoor air to the room 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 the ventilation system according to the general electrothermal 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.

As a related art, Korean Patent No. 10-1272674 discloses an increase in heat exchange efficiency during ventilation of indoor and outdoor air.

However, the electrothermal exchange type ventilator disclosed in the above-described prior arts has a limitation in use that is substantially used only for a single use in order to improve the heat exchange efficiency during ventilation.

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

In addition, Patent No. 10-1819046, filed by the applicant of the present invention and registered in the notification No. 10-1819046 divides the hollow duct body into a partition wall and installs a heat exchanger therein, the indoor air discharged and the outdoor air introduced into the heat exchange is At the same time, the air circulation control unit communicating with the filter device is installed on the front side of the total heat exchanger, so that the outdoor air can be ventilated in various modes according to the quality of the outdoor air. There is known a configuration using a filter device for ventilating the room cleanly so as to be switched to each mode.

However, the conventional electrothermal ventilation device as described above provides a variety of functions, but because it is provided with a duct for installing the outside air intake and indoor air discharge on the ceiling and the landfill is configured to ventilate the indoor air through them, studio or individual office space There is a problem in that installation is difficult.

In addition, since the conventional electrothermal ventilation apparatus is installed inside the ceiling, the ceiling of an aging building or school is made of a material that is fatal to health such as asbestos, and thus there is a problem that health and environmental problems may occur to remove and install them.

The intake fan 180 may also be operated to quickly supply the outside air to the room.

The inner circulation mode of the present invention, as shown in Figure 6,

When the outdoor air contains a lot of fine dust or yellow dust, it is carried out when it is not desirable to introduce outdoor air, and it is an operation mode for purifying the indoor air and supplying it back to the room. Opening the D1) and the fourth damper (D4) and the indoor air flows into the return chamber 110 through the vent 111 to supply to the lower left space 134 through the fourth damper (D4) After the indoor air is filtered through the heater filter 121 again, the indoor air is supplied to the upper right space 131 through the heat exchanger 120 and then introduced into the air supply chamber 140 through the first damper D1. And then resupplied to the room through the air supply pipe 150. In this case, the intake fan 180 is operated to quickly supply air introduced into the upper right space portion 131 to the air supply chamber 140.

In addition, the first damper (D1) is installed as a two-way damper that can supply the air introduced into the upper right space portion 131 to the air supply chamber 140, and can be operated in reverse.

The bypass ventilation mode of the present invention, as shown in Figure 8 and 9,

In the spring and autumn, since the indoor temperature is slightly higher than the outside temperature, there is a case where it is not necessary to recover the heat contained in the bet while operating the heat exchanger 120 and supply it to the room again. Therefore, in this case, the bet may be directly discharged to the outside through the bet discharge pipe 170 and the outside air may be simply supplied to the room by simply passing through without the operation of the heat exchanger 120. In this case, it is also possible to obtain the effect of reducing the cost of operating the total heat exchanger (120).

The bypass ventilation mode is divided into a bypass exhaust mode and a bypass air supply mode. In the bypass exhaust mode, the third damper D3 and the seventh damper D7 are opened by the control unit as shown in FIG. 8. After the indoor air flows into the upper left space 132 through the third damper D3, the indoor air is discharged to the outside through the seventh damper D7 and the internal air discharge pipe 170. At this time, by operating the exhaust fan 190 it is possible to quickly ventilate without passing through the other space. The bypass exhaust mode discharges bad air in the room to the outside, and since the bad air inside does not pass through the other space part, the possibility of contaminating the other space part is basically excluded.

In this case, the first damper D1, the second damper D2, the fourth damper D4, the fifth damper D5, and the sixth damper D6 are closed.

In the bypass air supply mode, as shown in FIG. 9, the first damper D1 and the sixth damper D6 are opened by the control unit, and the outside air passes through the external air supply engine 160 and the sixth damper D6. After flowing into the lower left space 134, the heater filter 121 and the heat exchanger 120 are introduced into the upper right space 131. Then, the air supply chamber is passed through the first damper D1. After entering the 140 is supplied to the room through the air supply pipe 150. At this time, the intake fan 180 may be operated to quickly perform ventilation. In this case, the second damper D2, the third damper D3, the fourth damper D4, the fifth damper D5, and the seventh damper D7 are closed.

When the bypass exhaust mode and the bypass air supply mode operate simultaneously, the first damper D1, the third damper D3, the sixth damper D6, and the seventh damper D7 are opened, and the second damper ( D2), the fourth damper D4 and the fifth damper D5 are closed.

As described above, the present invention operates the bypass ventilation mode as described above in the season when the indoor air is slightly higher than the outdoor air, such as spring and autumn, so that the air flowing into the room is not hot and can be ventilated more freshly. It can be discharged to the outside immediately without passing through other spaces, thereby preventing contamination of other spaces.

On the other hand, the air supply chamber 140 of the present invention may be added a guide tube (not shown) for inducing the flow of air uniformly. The guide tube starts from an upper portion of the first damper (D1) and continues to the lower end of the injection portion of the air supply pipe (150) and is installed through the air supply filter (141).
