Description

Ventilation system of the total heat exchanger connected to the filter box {A Ventilator}

The present invention relates to an indoor air ventilator, and more particularly, to purify the air introduced through the heat exchanger and the heat exchanger is installed once again so that the heat exchange is carried out while the indoor air and the external air crosses and supplies to the room again. It consists of a filter box which is connected to the external air supply passage as possible, and has a bypass passage between the indoor air discharge passage and the filter box, and the heat recovery that ventilates the room while the outdoor air enters the room through the heat exchanger and the filter box directly. Ventilation mode, indoor air clean mode that completely blocks the outdoor air and purifies the indoor air through the filter box, and supplies it back to the room, condensation removing mode to remove condensation of the heat exchanger, and dust filter installed in the filter box. It is a filter to switch the filter dust mode to remove dust of the room and to ventilate the room cleanly. Box relates to the ventilation of the heat exchanger is connected.

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.

If you look at the general configuration of the general heat exchange ventilator,

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, Patent Nos. 10-1272674 and 10-2008-0024379 disclose a uniform heat flow of indoor and outdoor air to increase heat exchange efficiency.

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.

Also, recently, due to the influence of fine dust and yellow dust, many air cleaners are separately installed in the room, but such air cleaners can only clean the air in some areas where they are located, and cannot clean the entire room, especially as partitions or rooms. In this case, a single air cleaner cannot clean the room.

In addition, when the outdoor air quality is very bad and the pollution degree is more severe than the indoor air, the ventilation further pollutes the indoor air, so the conventional heat exchanger has a limitation in purifying the indoor air.

In general, crowded exterior and enclosed buildings require regular ventilation and purification of the internal air as carbon dioxide is released through people's breathing and dust increases due to various causes. In addition, the concentration of carbon dioxide (C02) in the room should be regularly measured and kept below the reference value.

Therefore, a hollow duct is installed through a plurality of partition spaces in the ceiling of the building, and an electrothermal heat exchanger is installed in the interior of the building to send indoor air to the outside and to let outside fresh air into the room for ventilation. However, the prefilter installed in the total heat exchanger is very difficult and expensive because the duct inside the ceiling must be opened, repaired and replaced.

In addition, the space portion formed inside the building where people are active is provided with an air cleaning device for each space portion, and the space portion to purify the indoor air independently.

Therefore, a large number of air cleaning devices must be installed inside the building, which leads to a considerable amount of uneconomical factors, such as limited space utilization and cost.

As shown in FIG. 4, the heat recovery ventilator mode is operated when the quality of the outside air is good and the quality of the indoor air is improved only by the ventilation, and is controlled by the first damper (D1), the intake fan 126, and the first. 5 damper (D5), the eleventh damper (D11) is turned on, the outside air is the upper left space 121 of the heat exchange unit 120, the heat exchanger 110, the lower right space 124, the Enters the filter box 150 through the outdoor air supply passage 130 and is supplied to the fourth room (R4) through the fourth branch pipe (L4),

At the same time, while the second damper D2, the exhaust fan 125 and the fourth damper D4 are turned on, the indoor air of the fourth room R4 discharges the fourth exhaust branch pipe d and the indoor air. The passage 140 is discharged to the outside through the lower left space portion 123 through the upper right space portion 122 and the heat exchanger 110. As described above, the first to third rooms R1, R2, and R3 may also be ventilated.

At this time, the third damper (D3), the sixth damper (D6) provided in the bypass passage 160, the fan 152 provided in the filter box 150 is turned off. However, the fan 152 may be turned on when the entire first to fourth rooms R1, R2, R3, and R4 are simultaneously ventilated.

As shown in FIG. 4, the indoor air cleaning mode is operated when the quality of external air is not good, and the sixth damper D6, the eleventh damper D11, and the fan 152 are controlled by a control unit. Is ON,
