Description

Wall-embedded type Ventilation apparatus

The present invention relates to a ventilation device, and more particularly, a wall-embedded ventilation device in which intake of outdoor air and discharge of indoor air are performed by a single motor, and the indoor and outdoor air exchanges heat with each other to increase energy recovery rate. is about

In general, a ventilation device for maintaining clean indoor air by forcibly discharging indoor polluted air to the outside is a ventilator having a structure in which one fan is installed to induce a unidirectional air flow to discharge indoor air to the outside. .

These fans are generally installed on glass windows and assume that the inflow of indoor and outdoor air through the gaps in the windows or doors due to the exhaust of indoor air to the outside. As the glass window or door expands and contracts with a closed structure, the density of indoor air is weakened due to the single use of the fan, resulting in a very dangerous situation.

Accordingly, in recent years, a ventilation fan having a double fan structure that allows outdoor air to be introduced into an indoor space and indoor air to be discharged to the outdoors at the same time has been developed.

The fan with this double fan structure uses a single motor and installs a fan on one or both motor shafts, and each fan draws in indoor air and discharges it to the outdoors. It has the effect that intake and exhaust of indoor air and outdoor air are made simultaneously by being provided in the discharge passage.

A fan with such a double fan structure has the advantage of always maintaining fresh indoor air with only one fan in an enclosed space, and is very useful in spring and autumn when the temperature difference between indoor and outdoor is not high because intake and exhaust are performed at the same time. On the other hand, there is an advantage of being able to use it comfortably, but a factor of wasting energy occurs in summer or winter when air conditioning is performed due to a large temperature difference between indoor and outdoor.

In other words, in winter, because heating is performed indoors, considerable heat is lost during the ventilation process and heating efficiency is lowered. There is a problem in that the cooling efficiency is lowered.

In order to solve this problem, a heat exchange unit is provided inside the ventilator in which outdoor air is sucked and indoor air is discharged by a single motor, and indoor and outdoor air is intake and exhausted while the indoor and outdoor air is in contact with the heat exchange unit to increase the energy recovery rate. Ventilation systems for tall buildings have also been developed.

However, when installing such a ventilation device on a wall, not only is it difficult to install, but also leaves, insects, and other pollutants may be deposited on the part that protrudes to the outside. Heat exchange has to take place and the indoor air must be exhausted.

Therefore, it is possible not only to selectively exchange heat between exhausted indoor air and sucked in outdoor air, but also to circulate only indoor air for purification of indoor air. A buried ventilation system became necessary.

As shown in FIG. 3, when the indoor damper does not require heat exchange with the air sucked into the room, the air entering the indoor air outlet from the left and right of the indoor air outlet is blocked by the indoor damper and passes through the central space of the indoor air outlet to remove the ventilation filter. It does not pass through and does not flow to the total heat exchange element, and flows from the left and right spaces formed on the left and right sides of the indoor air exhaust unit by the indoor damper to the space formed on the left and right between the circular housing and the total heat exchange element. let it pass

On the other hand, if heat exchange with the air coming into the room from the outside is required when discharging the indoor air, the left and right indoor dampers rotate 90 degrees by the operation of a motor (not shown) connected to the indoor damper, so that the left and right spaces and the center of the indoor air outlet As it communicates the space and at the same time blocks the passage of the indoor air outlet of the space formed on the left and right between the total heat exchange element and the circular housing,

The air flow through the left and right spaces formed by the circular housing and the total heat exchange element is blocked, and the indoor air entering the indoor air outlet passes through the ventilation filter and exits through the total heat exchange element. After entering the lower space formed by the exchange element, it passes vertically through the total heat exchange element, flows into the upper space formed by the circular housing and the total heat exchange element, and then enters the room. At this time, the air and length passing vertically through the total heat exchange element The air flowing in the direction exchanges heat with each other.

The left side wall of the fan case part has an open central part, has a certain thickness, has a rim protruding to the outside, and is formed in a circular shape as a whole to be sealed in combination with a circular housing or a fan case housing, but the lower part of the left wall is a total heat exchange element It is formed in a straight line to correspond to the lower edge of the total heat exchange element at the portion in contact with the lower part of the total heat exchange element and is in direct contact with the side surface of the total heat exchange element. It cannot escape to the lower part of the fan case.

In addition, a separate protrusion 335 is formed on the left side wall portion of the fan case portion in contact with the upper right side of the total heat exchange element so as to correspond to the height of the rim protrusion, and is in contact with the upper right surface of the total heat exchange element. Air between the spaces formed between the left side walls of the sub-left was prevented from escaping to the upper part.

The air discharged from the room flows through the total heat exchange element in the left and right longitudinal directions when heat exchange is made with the air sucked into the room through the total heat exchange element as described when describing the indoor part. If heat is not exchanged with the air sucked in through the furnace, it flows through the space on the left and right sides of the circular housing and the total heat exchange element. After entering the space formed at the portion where the right side of the exchange element abuts, it enters the first space of the fan case through the central portion of the left wall.

Meanwhile, FIG. 6 shows a right perspective view in which the fan case part and the electric damper are combined.

The right wall of the fan case part has an open central part, has a certain thickness, has a protruding edge, and is generally circular, so that it is sealed with a circular housing or fan case housing, but the upper part is a circular housing or fan case housing and air The top of the right wall circle is cut in a straight line to create space for flow.

In order to prevent direct contact with the electric damper or motor even if it penetrates into More may be provided.

The outdoor part can prevent the failure of the electric damper from rain or fallen leaves and dust, and it is possible to easily clean sediments such as fallen leaves accumulated on the outside of the outdoor part casing due to the detachable attachment and detachment of the outdoor part casing. can

Figure 8 is an air flow when heat exchange occurs between outdoor intake air and indoor exhaust air through the total heat exchange element. It shows the air flow when the indoor air is purified by the installed filter.

That is, in FIG. 8, indoor air passes through the first space of the fan case through the center of the indoor air outlet and the total heat exchange element of the indoor unit, and exits to the outdoors, and the outdoor air sucked through the lower end of the outdoor unit is the After passing through the second space from the lower part to the upper part of the total heat exchange element, heat exchange with the indoor air discharged is made, and then it enters the room.

9 shows a mode for circulating indoor air when only purification of indoor air is required. Since indoor air passes through the ventilation filter and the filter installed in the outdoor air supply unit of the indoor unit, contaminants in the indoor air are naturally caught.

At this time, in the total heat exchange element, heat exchange is performed between the air discharged from the room and the air sucked into the room.

On the other hand, if heat exchange through the total heat exchange element is meaningless and you want to simply exhaust indoor air and suck fresh outdoor air into the room, you can select the bypass mode.

In this mode, indoor air is discharged through passages on the left and right sides of the indoor air outlet of the indoor unit, passes through the left and right surfaces of the total heat exchange element, passes through the first space of the fan case, and is discharged to the outdoors. It enters the room while passing from the lower part to the upper part of the total heat exchange element through the second space of the fan case part through the lower end of the outdoor part. Since it moves to the space formed between the and the circular housing, heat exchange with the air entering the room from the total heat exchange element is not performed.
