Description

The present invention relates to a temperature control device for a ventilator. More specifically, the present invention minimizes the space occupied at the installation position of a ventilation system for ventilating a residential or office space, is directly connected to the ventilation system, and reduces the heat loss and internal condensation phenomena that can occur in the ventilation mode. It relates to a temperature control device for a ventilator that can be minimized and even provide an antibacterial function.

The indoor air ventilation function was generally provided only in large buildings such as office spaces or factories. Recently, however, newly built apartments often provide each household with a ventilation function to control the degree of indoor air pollution. As indoor activities become more active, indoor air becomes more polluted. Therefore, a ventilation process is required to periodically supply fresh outdoor air to the indoors and exhaust polluted indoor air to the outdoors. Recently, the need for indoor air ventilation has become an issue due to reasons such as combustion gases for cooking, sick house syndrome, and Oldhaus syndrome.

Such ventilation is preferable in terms of supplying fresh air to the room and expelling polluted air to the outside, but it also expels the heated (or cooled) room air at the optimal temperature to the outside. Heat loss (increase in air conditioning load or energy loss) occurs in the process of inflowing cold (or hot) air into the room. In order to prevent possible heat loss during the ventilation process, the ventilation system shall be equipped with a heat exchanger for heat exchange between the air supplied to the room and the air discharged to the outside. Since the temperature difference between the fast-flowing supply air and the exhaust air is seldom small, a pure ventilation operation with complete cutoff of heat loss is not possible.

In addition, with conventional ventilation systems, there is a large temperature difference between the indoor air discharged from the room and the outdoor air supplied to the room in winter, etc., so dew condensation occurs in the flow path inside the ventilation system or near the heat exchanger. will occur. If the dew condensation phenomenon is repeated, the heat exchange efficiency between the exhaust air and the supply air of the heat exchanger is lowered, and the moisture generated by the dew condensation phenomenon promotes the propagation of bacteria.

Since it is difficult for the user to clean the inside of the ventilator due to its structure, if the dew condensation phenomenon occurs repeatedly inside the ventilator, the air supplied to the room by the ventilator will be polluted, causing a sanitary problem. Become.

A general form of a ventilator equipped with a heat exchanger applied to recent apartments has a flat rectangular parallelepiped shape, and is mounted on the ceiling of a space such as a veranda so as to minimize the occupation of the veranda living space. Adopt a structure that exhausts or supplies indoor air and outdoor air and minimizes heat loss with a heat exchanger.

New additional equipment can be considered to solve the above-mentioned problems, but it can also be applied to spaces where general ventilation equipment is installed, solving problems due to narrow space restrictions. Although there is a demand for a method capable of doing so, no such additional equipment has been proposed yet.

The present invention minimizes the occupied space at the installation position of the ventilation device that ventilates the residential space and office space, is directly connected to the ventilation device, minimizes the heat loss and internal condensation phenomenon that may occur in the ventilation mode, and even has an antibacterial function.

Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. This invention may, however, be embodied in other forms and should not be construed as limited to the embodiments set forth herein. Rather, the embodiments presented are provided so that this disclosure will be thorough and complete, and will fully convey the spirit of the invention to those skilled in the art. Like reference numerals refer to like elements throughout the specification.

FIG. 1 is a plan view of a residential space in which a ventilation system according to an embodiment of the present invention is installed, and FIG. 2 is a diagram showing a ventilation device that constitutes the ventilation system of FIG. 1 attached to the ceiling of an air-conditioned room. .

As shown in FIGS. 1 and 2, the ventilation system according to the embodiment of the present invention includes a ventilation device 100, a temperature control device 200, ventilation ducts 10a and 10b, and indoor diffusers 140a and 140b connected to the ventilation ducts 10a and 10b. can be understood to be of a concept that includes

Since ventilation pipes are mainly arranged on the indoor ceiling, the ventilation device 100 can also be installed on the ceiling of an air-conditioned room as such as a veranda, as shown in FIG. The ventilation device 100 constituting the ventilation system of the present invention according to the embodiment of the present invention is a heat recovery type ventilation device, and the ventilation system of the present invention may further include a temperature control device 200 .

For example, the temperature control device 200 of the present invention can be vertically connected to the ventilator 100 maintaining a horizontal state on the bottom when viewed from the side of the ventilator 100, installed on the ceiling. The structure of the temperature control device 200 of the present invention is described in more detail below.

Ventilation ducts 10a and 10b are installed on one side of the ventilation device 100, and the temperature control device 200 is installed on the other side. not shown) can be connected.

A ventilator 100 according to an embodiment of the present invention can supply or exhaust indoor air to supply or exhaust diffusers 20a, 20b.

As shown in Fig. 2, the air-conditioned room as where the ventilation system is installed is used as a space such as a veranda or a multi-purpose room, and the size of the motor and heat exchanger to ensure sufficient ventilation and heat exchange is selected. Considering this, the width of the ventilator 100 in the air flow direction can occupy most of the width of the air conditioning room in the indoor and outdoor directions.

However, as described above, in order to connect additional equipment to the ventilation system in series to prevent dew condensation or contamination inside the ventilation system, it is necessary to extend the piping downward from the ventilation system 100 and install it in a place other than the ceiling. Additional equipment must be installed in the air-conditioning room and connected so that the air that has passed through the additional equipment is sent to the outdoor direction again.

However, in the temperature control device 200 of the present invention shown in FIG. 2, the thickness of the upper region is small and the thickness of the lower region is relatively large. A region is attached, and the lower region of the temperature control device 200 extends below the upper region and can provide temperature control or antibacterial functions in its interior space.

The temperature control device 200 for a ventilator according to the present invention will be described in detail with reference to FIG. 3 and subsequent drawings.

As shown in FIG. 3, the ventilation device 100 is installed horizontally and the temperature control device 200 is installed vertically. It can form an L' shape.

As described above, the space between the ventilator 100 and the wall surface of the outdoor side is narrow, and the ventilator 100 having a constant volume is usually placed at the outer edge of the air-conditioned room such as a veranda to avoid interference with the space of the air-conditioned room. Try to minimize aesthetic disturbances. In such an installation environment of the ventilation device, the upper region of the temperature control device 200 is arranged between the ventilation device and the outdoor wall surface, and the region that performs the temperature control function or the antibacterial function corresponding to the lower region is the ventilation device. In the case of horizontal installation, the occupied area of the ceiling of the air conditioning room increases, and a separate ceiling fixing work is required to support the load of the temperature control device. In addition, there may be installation variables related to the installation environment, such as interference with lighting installed on the ceiling.

However, when using the method of installing the upper region of the temperature control device 200 in the space between the ventilator 100 and the outdoor wall surface and arranging the lower region below, the spatial limitation can be minimized. , Workability can be improved.

The present invention is a temperature control device for a ventilator installed on the outdoor side of a ventilator 100 having a total heat exchanger 130 and an air supply port and an air exhaust port on opposite sides. A housing 210 is divided into a lower area lp, a pair of air inlets 270 and 280 through which air is introduced into opposite sides of the upper area UP, and air is discharged through opposite sides of the upper area UP. and an exhaust port 260 and an air supply port 270 provided on the outdoor side of the upper region up, and the exhaust port 260 and the air supply port 270 are selectively opened and closed. a first damper member 261 and a second damper member 271, and a third damper member 281 provided in the lower region lp for selectively blocking the inflow of indoor air from the ventilator 100; The air supply and exhaust ports 260 and 280 face each other and are offset from the other pair of air supply and exhaust ports 250 and 270, and are opened and closed by opening and closing the first to third damper members 261 to 281. An air purification mode that removes pollutants from the indoor air and resupplies it indoors, a ventilation mode that exhausts the indoor air to the outdoors and supplies the outdoor air indoors, or a part of the indoor air is mixed with the outdoor air and sent indoors It is possible to provide a temperature control device 200 for a ventilator, which is driven in a temperature control ventilation mode that supplies air and exhausts the rest of the room air to the outside.

The present invention is a temperature control device 200 for a ventilator installed on the outdoor side of the ventilator 100 having a total heat exchanger 130 and having air supply ports 150, 170 and exhaust ports 160, 180 on opposite sides, respectively. A housing 210 of the temperature control device 200 is divided into an upper region lp and a lower region lp. A pair of air inlets and outlets 260 and 280 may be opposed to each other, and the other pair of air inlets and outlets 250 and 270 may be displaced.

The ventilation device 100 equipped with the temperature control device 200 of the present invention includes a total heat exchanger 130 for reducing the temperature difference between supply air and exhaust air, at least one filter unit 140a for filtering pollutants in the supply air, 140b, and at least one blower fan (not shown). The total heat exchanger 130 is configured in a way that flow paths intersect, and may be of a type that performs heat exchange of flowing air. do.

In addition, the ventilator 100 may be provided with a pair of air supply ports 150 and 170 and a pair of air exhaust ports 160 and 180 on the indoor and outdoor side surfaces, respectively.

The air supply port and the air exhaust port connecting the flow paths are connected in a diagonal direction, so that the supplied air and the exhausted air can flow in the indoor direction and the outdoor direction.

The temperature control device 200 of the present invention includes air inlets 270 and 280 through which air is introduced and outlets 250 and 260 through which air is discharged, respectively, on opposite sides of the upper region lp. The air outlets 260 and 280 face each other, and the other pair of air inlets and air outlets 250 and 270 are offset from each other. A first air supply port 280 through which the exhaust air from the ventilation device 100 flows into the temperature control device 200 and a first exhaust port 260 through which the exhaust air is discharged to the outside of the room may be provided.

In addition, a pair of air inlets and air outlets provided in the upper region lp of the temperature control device 200 are separated from each other through a second air inlet 270 through which outdoor air is supplied and the lower region lp. It may be the second exhaust port 250 through which air is supplied to the room.

The indoor air supplied to the first air supply port 280 provided in the upper region lp is entirely exhausted to the outside through the first exhaust port 260, or is passed through the lower region lp of the temperature control device 200 into the room. Alternatively, part of it may be discharged to the outside through the first exhaust port 260, and the rest may be mixed with outdoor air introduced through the second air supply port 270 and supplied to the room.

In addition, the outdoor air supplied from the second air supply port 270 provided in the upper region lp is supplied to the room alone through the second air outlet 250 and the ventilation device 100, or is supplied to the room through the first air supply. The air is supplied to the outlet 280 and is not discharged to the outside, but is mixed with the room air passing through the lower region lp and is supplied to the room through the second exhaust port 250 and the ventilator 100 .

Here, when the room air supplied from the first air supply port 280 through which the room air is supplied to the upper region lp is discharged to the outside, the room air passes through the upper region lp through the first exhaust port 260. There is a difference in that the outdoor air that is exhausted but is supplied through the second air supply port 270 bypasses the lower region lp and is supplied to the room through the second exhaust port 250 and the ventilator 100 .

The upper region lp of the temperature control device 200 provides a flow path determination function, and the lower region lp of the temperature control device 200 can perform a temperature control function, a filtering function, or an antibacterial function by mixing air passing through.

3 and 4, the width of the upper region lp of the temperature control device 200 may match the width of the ventilator 100, and the thickness w2 of the lower region lp is the thickness of the upper region lp. can be greater than the thickness w1.

Also, the thickness h1 of the ventilator 100 and the height h2 of the upper region lp may be the same. That is, stepped portions 211 and 213 corresponding to the difference between the thickness w1 of the upper region lp and the thickness w2 of the lower region lp may be provided between the upper region lp and the lower region lp of the temperature control device 200. Also, the ventilation device 100 seated on the stepped portions 211 and 213 may be constructed so as not to protrude outside the upper region lp of the temperature control device 200 in width and thickness directions.

The width of the stepped portions 211 and 213 formed in the housing of the temperature control device 200 is such that the stepped portion 213 facing the room is larger than the stepped portion 211 facing the outside, so that a sufficient space is provided inside the lower region lp. While securing the temperature, the size or thickness of the ventilating device 100 and the temperature control device 200 that are assembled together can be minimized.

Also, the thickness w2 of the lower region lp of the temperature control device 200 is greater than the total thickness w1 of the upper region lp. It was experimentally confirmed that the total thickness of the lower region lp is preferably 1.5 to 5 times the thickness w1 of the upper region lp.

That is, when the thickness w2 of the lower region lp is less than 1.5 times the thickness w1 of the upper region lp, the thickness of the lower region lp is sufficient to perform the temperature control function, filtering function or antibacterial function. If the inner space cannot be secured and the thickness w2 of the lower region lp is more than five times the thickness w1 of the upper region up, the size of the inner space of the lower region lp is large and the ventilator 100 We were able to confirm that the output of the blower fan of the

In addition, clamps 233 for clamping the side edges of the ventilator 100 are provided at the upper and lower ends of the upper region lp of the temperature control device 200, thereby improving the assembling efficiency and improving the assembling state. It can be supported stably.

A damper member for selectively blocking a flow path is provided on the air supply port and the air exhaust port provided on both sides of the upper region lp, respectively. can be done.

Specifically, as shown in FIGS. 3 and 4, by providing first and second damper members 261 and 271 on the first exhaust port 260 and the second air supply port 270, respectively, the above- described The first exhaust port 260 and the second air supply port 270 can be closed, the first exhaust port 260 and the second air supply port 270 can be opened in the ventilation mode, and the first exhaust port 260 and the second air supply port 270 can be opened in the temperature control ventilation mode. The opening degrees of the exhaust port 260 and the second air supply port 270 can be adjusted.

In addition, a third damper member 281 (see FIG. 5) may be further provided in the lower region lp of the temperature control device 200 . The third damper member 281 may selectively block a path through which indoor air supplied from the ventilator 100 detours in the lower region lp.

A detailed description of such air purification mode, temperature control ventilation mode and general ventilation mode will be disclosed with reference to FIGS.

That is, the damper members 261, 271, and 281 are provided only with a damper member for blocking the flow path and a driving motor for driving the damper member, so that a separate fan unit can be omitted and the temperature control device can be used. The controller can adjust the opening of the damper member only by controlling the rotation of the motor.

FIG. 5 shows air flow paths when the ventilator 100 and the temperature control device 200 of the present invention are operated in the air purification mode.

In the air purification mode, the first damper member and the second damper member in the upper area up are controlled to be in a closed state, and the third damper member 281 in the lower area lp is controlled to be in an open state. As room air through 100 circulates through the lower region lp, contaminants are filtered and can be supplied to the ventilator 100 through the upper region up.

For this purpose, the lower region lp of the temperature control device may include a filter unit 290 for removing dust from the indoor air, the outdoor air, or the mixed air of the indoor air and the outdoor air. In addition, for the antibacterial treatment inside the temperature control device, the ventilation device or the ventilation duct, the lower region lp of the temperature control device may add a phytoncide liquid to the indoor air, the outdoor air, or the mixed air of the indoor air and the outdoor air. A phytoncide liquid injection part 240 for injecting may be further provided.

Phytoncide is a substance that plants spurt or secrete to resist pathogens, pests, and fungi. Exposure to phytoncide relieves stress, strengthens intestinal and cardiopulmonary functions, and has bactericidal action. Therefore, by spraying a concentrated phytoncide liquid in the form of a mist into the air flowing through the flow path, the temperature control device, the ventilation device (especially the area around the total heat exchanger or the ventilation fan) and the entire ventilation duct can sterilize or provide the function of preventing bacterial growth.

The phytoncide liquid injection part 240 can be controlled to be periodically or intermittently injected only according to a predetermined schedule or conditions, and the phytoncide liquid is replenished or the phytoncide liquid container is controlled by a temperature control device. (not shown) can be configured to be interchangeable.

The filter part 290 may include at least one or both of a HEPA filter 291 and an activated carbon filter 293 .

Therefore, when the temperature of the outdoor air is too low or too high, ventilation of the indoor air is unnecessary, but purification of the indoor air is necessary, as shown in FIG. Can work in air purification mode.

In this case, when the temperature control device 200 is driven in the air purification mode, exhaust of indoor air and supply of outdoor air are unnecessary, so that all the damper members in the upper region UP are controlled to be in a closed state. A damper member in the lower region lp can be controlled to be in an open state. Specifically, if the ventilation device 100 is driven with the first damper member 261 and the second damper member 271 controlled to be in a closed state and only the third damper member 281 is controlled to be in an open state, contamination will occur. As the indoor air passes through the ventilation device 100, pollutants are removed by the filter unit 290, and the phytoncide solution is sprayed from the phytoncide solution spraying unit 240 to be antibacterially treated. A room can be supplied via the device 100 .

In general, the ventilator 100 also has the filter units 140a and 140b, but the performance of the filter units 140a and 140b is not sufficient, and replacement is not easy.

However, as shown in FIG. 4, the temperature control device 200 of the present invention has control openings 202 that can be opened and closed so that the inner space of the lower region lp can be approached in the direction of the room that is lower than the ventilation device 100. Since the filter 203 is provided, it is easy to replenish the replacement phytoncide solution of the filter constituting the filter part 290 .

Since the lower region lp of the temperature control device 200 is lower than the ceiling, it is possible to easily access the control ports 202 and 203, so maintenance and management of the filter part 290 or the phytoncide liquid spraying part is easier than replacing the filter of the ventilation device 100. Since it can be easily performed, effective measures for reducing particulate matter contained in the ventilated air have been developed so as to eliminate the anxiety of users who hesitate to ventilate due to increasingly severe particulate matter. can provide a solution.

In addition, a space between the management ports 202 and 203 may be provided with an accommodation space 201 for accommodating a phytoncide solution supply unit or a control unit.

The indoor air flowing through the upper region up and passing through the lower region lp is made to flow along a '∪'-shaped flow path, and a vertical '∪' flow path is used to treat the air flowing horizontally. The addition of glyph channels has the effect of minimizing the thickness or horizontal width of the temperature control device.

FIG. 6 shows the air flow path when the ventilation device 100 and the temperature control device 200 of the present invention are operated in the general ventilation mode. The temperature difference between the outdoor air and the indoor air is not large and ventilation is necessary.

In the ventilation mode, the first damper member and the second damper member in the upper region UP are controlled to be open, and the third damper member 281 in the lower region lp is controlled to be closed, so that the ventilator 100 The indoor air passed through the upper region up of the temperature control device is discharged to the outside, and the air supplied from the outside passes through the lower region lp and is supplied to the ventilator 100 through the upper region up. be able to.

As shown in FIG. 6, the indoor air heat-exchanged through the ventilator 100 is supplied to the first air supply port 280 of the temperature control device 200 and discharged to the outside through the first exhaust port 260. is supplied through the second air supply port 270, filtered while passing through the inner space of the lower region lp, and the phytoncide liquid is injected, and then the second exhaust port 250 of the upper region lp and the total heat exchanger 130 can be supplied to the room through a ventilation device 100 with

In this case, when the temperature control device 200 is driven in the ventilation mode, the damper members of the upper region lp can be controlled to be open, and the damper members of the lower region lp can be controlled to be closed.

Specifically, if the ventilator 100 is driven with the first damper member 261 and the second damper member 271 controlled to be in an open state and only the third damper member 281 is controlled to be in a closed state, the ventilator 100 The air flowing into the temperature control device 200 through the third damper member 281 can be discharged without passing through the lower region lp of the temperature control device 200 . On the other hand, the outdoor air flowing into the temperature control device 200 has pollutants removed by the filter unit 290, is antibacterially treated by spraying phytoncide liquid, and is then supplied to the room through the second exhaust port 250 and the ventilation device 100. can be

In this case, outdoor air flowing through the upper region up and passing through the lower region lp may form a '∪'-shaped flow path.

FIG. 7 shows the air flow path when the ventilator 100 and the temperature control device 200 of the present invention are operated in the temperature control ventilation mode.

In the temperature control ventilation mode, the first damper member and the second damper member in the upper region up are controlled to be partially open, and the third damper member 281 in the lower region lp is controlled to be open or partially open. As a result, part of the indoor air that has passed through the ventilation device 100 is mixed with the outdoor air supplied from the outside through the upper region up in the lower region lp, and supplied to the ventilation device 100 through the upper region up. , the rest of the room air that has passed through the ventilator 100 can be discharged to the outside through the upper region up.

If indoor air ventilation and decontamination are all required, but the temperature difference between indoor and outdoor air is large and energy losses are expected to be large when operating in general ventilation mode, the temperature of the present invention The control device 200 can be driven in a temperature control ventilation mode.

When the temperature control device 200 is driven in the temperature control ventilation mode, the damper member of the upper region lp is controlled to be partially open, and the damper member of the lower region lp is controlled to be open or partially open. can

That is, when the ventilator 100 is driven with the first damper member 261, the second damper member 271, and the third damper member 281 partially opened, the indoor air flowing into the temperature controller 200 through the ventilator 100 is driven. Part of the air flows into the lower region lp of the temperature control device 200 and the rest of the air is discharged to the outside through the first exhaust port 260 . Since the third damper member 281 is also in an open or partially opened state, the air flowing in the lower region lp flows toward the filter unit 290, and since the second damper member 271 is also in an open state, Air is supplied through the second air supply port 270, mixed with the indoor air, pollutants are removed by the filter unit 290, and after being antibacterially treated by spraying phytoncide liquid, the air is discharged through the second exhaust port 250 and the ventilation device. Via 100 can be fed into the room.

That is, the indoor air and the outdoor air are partially mixed to minimize energy consumption or thermal shock, and pollutants that may exist in the outdoor air are filtered as the mixed air passes through the filter unit, and the phytoncide liquid injection unit 240 filters the pollutants. It can even be antibacterial treated.

In this case, each of the outdoor air, the indoor air, and the mixed air flowing through the upper region up and passing through the lower region lp may form a '∪'-shaped flow path.

5-7, each damper member 261, 271, 281 can be expected to open to 45 degrees when closed, opened, or partially opened, but Considering the temperature difference with the room or the amount of heat loss, the opening degree of at least one of the damper members in the upper region lp and the lower region lp in the partially open state and the opening degree of the remaining damper members are mutually adjusted. It can be configured differently (eg 30 degrees or 60 degrees). In summary, the opening degree of at least one of the damper members in the upper region up and the lower region lp in a partially open state and the opening degree of the remaining damper members may be different from each other.
