Description

The present invention relates to a temperature control device for a ventilation device. More specifically, the present invention minimizes the occupied space at the installation position of the ventilation device that ventilates the living space or office space, and directly connects to the ventilation device to reduce the heat loss and internal dew condensation phenomenon that can occur in the ventilation mode. It relates to a temperature control device for a ventilation device that can be minimized and even provide an antibacterial function.

Normally, the indoor air ventilation function was generally provided only in a large building such as an office space or a factory. However, these days, it is often the case that each household in a newly built apartment building is provided with a ventilation function to control the degree of indoor air pollution. If the indoor activity becomes active, the degree of pollution of the indoor air will increase, so a ventilation process that periodically supplies fresh outdoor air to the room and discharges the polluted indoor air to the outside is necessary. Recently, the need for ventilation of indoor air has become an issue because of combustion gas for cooking, sick building syndrome, or the group of sick building syndromes.

Such ventilation is preferable in terms of supplying fresh air to the room and discharging the contaminated air to the outside, but it discharges the indoor air heated (or cooled) at the optimum temperature to the outside. In the process of flowing cold (or hot) air into the room, heat loss (increased air conditioning load or energy loss) will be caused. In order to prevent heat loss that may occur in the ventilation process, the ventilation system is equipped with a heat exchanger for heat exchange between the air supplied to the room and the air discharged to the outside, but on the intersecting flow paths. Since it is rare that the temperature difference between the supply air flowing at high speed and the exhaust air becomes small, pure ventilation operation that completely shuts off heat loss is impossible.

In addition, since the temperature difference between the indoor air discharged from the room and the outdoor air supplied to the room is large in the conventional ventilation device, dew condensation occurs in the internal flow path of the ventilation device or in the vicinity of the heat exchanger. It will occur. If such a dew condensation phenomenon is repeated, the heat exchange efficiency between the exhaust air and the air supply by the heat exchanger will decrease, and the water generated by the dew condensation phenomenon will promote the growth of bacteria.

Since it is structurally difficult for the user to clean the inside of the ventilation system, if the phenomenon of dew condensation occurs repeatedly inside the ventilation system, it causes a hygienic problem that rather pollutes the air supplied to the room by the ventilation system. Become.

The general form of a ventilator with a heat exchanger, which is applied to modern apartments, has a flat rectangular shape and is mounted on the ceiling of a space such as a veranda so as to minimize the occupancy of the veranda living space. A structure is adopted in which indoor air and outdoor air are exhausted or supplied, and heat loss is minimized by a heat exchanger.

Although new additional equipment to solve the above-mentioned problems can be considered, it can be additionally applied to the space where a general ventilation system is installed, and even the problem due to the limitation of a narrow space can be solved. There is a demand for a method that can be used, but such additional equipment has not yet been proposed.

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

(Not shown) can be concatenated.

The ventilation device 100 according to the embodiment of the present invention can supply or exhaust indoor air to the diffusers 20a and 20b for supply or exhaust.

As shown in Fig. 2, the air-conditioning room as where the ventilation system is installed is used as a space such as a veranda or a multipurpose room, and the size of the motor and heat exchanger to secure sufficient ventilation and heat exchange is used. Considering this, the width of the ventilation device 100 in the flow direction can occupy most of the width in the indoor / outdoor direction of the air conditioning chamber.

However, as described above, in order to connect the additional equipment for preventing dew condensation or contamination inside the ventilation device in series with the ventilation device, the piping is extended downward from the ventilation device 100, and the other place other than the ceiling. Since additional equipment must be installed in the room and connected so that the air that has passed through the additional equipment is sent in the outdoor direction again, the piping becomes complicated and the space of the air conditioning room is considerably occupied.

The air supply port and the exhaust port 260, 280 face each other, and are arranged 270 apart from the other pair of air supply port and the exhaust port 250, and by opening and closing the first damper member 261 to the third damper member 281. An air purification mode that removes contaminants from the indoor air and resupplyes it indoors, a ventilation mode that discharges the indoor air to the outside and supplies the outdoor air to the room, or a ventilation mode in which part of the indoor air is mixed with the outdoor air and enters the room. It is possible to provide a temperature control device 200 for a ventilation device, which is driven in a temperature control ventilation mode for supplying and discharging the rest of the room air to the outside of the room.

The present invention is a temperature control device 200 for a ventilation device, which is equipped with a total heat exchanger 130 and is mounted on the outdoor side surface of a ventilation device 100 provided with air supply ports 150 and 170 and exhaust ports 160 and 180 on facing side surfaces. The housing 210 of the temperature control device 200 is divided into an upper region lp and a lower region lp, and the temperature control device 200 has air supply ports 270 and 280 and air flowing into the facing side surfaces of the upper region lp, respectively. The exhaust ports 250 and 260 are provided, respectively, and the pair of air supply ports and the exhaust ports 260 and 280 can be arranged so as to face each other and the other pair of air supply ports and the exhaust ports 250 and 270 to be separated from each other.

The ventilation device 100 to which the temperature control device 200 of the present invention is mounted includes a total heat exchanger 130 for reducing the temperature difference between the supply air and the exhaust gas, and at least one filter unit 140a for filtering contaminants in the supply air. It can include 140b, and at least one blower fan (not shown). Since the total heat exchanger 130 is configured by a method in which flow paths intersect and can perform heat exchange of flowing air and is related to a general ventilation device 100, detailed description thereof will be omitted. do.

Further, the ventilation device 100 may be provided with a pair of air supply ports 150 and 170 and exhaust ports 160 and 180 on the side surfaces in the indoor direction and the outdoor direction, respectively.

By communicating the air supply port and the exhaust port connecting the respective flow paths in the diagonal direction, the air supplied and the air exhausted can flow in the indoor direction and the outdoor direction.

The temperature control device 200 of the present invention includes air supply ports 270 and 280 for air to flow in and exhaust ports 250 and 260 for air discharge on both facing surfaces of the upper region lp, respectively, and has a pair of air supply ports and a pair of air supply ports and 260. The exhaust ports 260 and 280 face each other, and the other pair of air supply ports and exhaust ports 250 and 270 are arranged so as to be offset from each other. It can be a first air supply port 280 in which the exhaust air via the ventilation device 100 flows into the temperature control device 200 and a first exhaust port 260 in which the exhaust air is discharged to the outside of the room.

Further, the pair of offsetly arranged air supply ports and exhaust ports provided in the upper region lp of the temperature control device 200 pass through the second air supply port 270 to which the outdoor air is supplied and the lower region lp. It can be the second exhaust port 250 to which air is supplied to the room.

All of the indoor air supplied to the first air supply port 280 provided in the upper region lp is discharged to the outside through the first exhaust port 260, or indoors via the lower region lp of the temperature control device 200. The whole amount can be recovered, or a part of the air can be discharged to the outside through the first exhaust port 260, and the rest can be mixed with the outdoor air flowing in through the second air supply port 270 and supplied to the room.

Further, the outdoor air supplied from the second air supply port 270 provided in the upper region lp is independently supplied to the room via the second exhaust port 250 and the ventilation device 100, or the first air supply port. It is supplied to the port 280, is not discharged to the outside, is mixed with the room air via the lower region lp, and can be supplied to the room via the second exhaust port 250 and the ventilation device 100.

Here, when the indoor air supplied from the first air supply port 280 to which the indoor air is supplied to the upper region lp is discharged to the outside of the room, the indoor air passes through the upper region lp through the first exhaust port 260. Although it is discharged, the outdoor air supplied through the second air supply port 270 bypasses the lower region lp and is supplied into the room through the second exhaust port 250 and the ventilation device 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.

Then, as shown in FIGS. 3 and 4, the width of the upper region lp of the temperature control device 200 can match the width of the ventilation device 100, and the thickness w2 of the lower region lp is the upper region lp. Thickness can be greater than w1.

Further, the thickness h1 of the ventilation device 100 and the height h2 of the upper region lp can be matched. 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. The ventilation device 100 seated on the step portions 211 and 213 can be configured so as not to protrude to the outside of the upper region lp of the temperature control device 200 in the width direction and the thickness direction.

The width of the step portions 211 and 213 formed in the housing of the temperature control device 200 is a sufficient space inside the lower region lp because the indoor direction step portion 213 is configured to be larger than the width of the outdoor direction step portion 211. It is possible to minimize the size or thickness of the ventilation device 100 and the temperature control device 200 protruding to the outside of the room in the assembled state.

The thickness w2 of the lower region lp is larger than the total thickness w1 of the upper region lp of the temperature control device 200. It was experimentally confirmed that the total thickness of the lower region lp is preferably configured to have a size of about 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 smaller than 1.5 times the thickness w1 of the upper region lp, the lower region lp sufficient to perform the temperature control function, the filtering function or the antibacterial function. When the internal space cannot be secured and the thickness w2 of the lower region lp is larger than 5 times the thickness w1 of the upper region up, the size of the internal space of the lower region lp is large and the ventilation device 100 It was confirmed that the output of the blower fan may be insufficient.

Then, the clamp 233 for seating and clamping the side surface end portion of the ventilation device 100 is provided at the upper end and the lower end of the upper region lp of the temperature control device 200, thereby improving the assembling property and improving the assembled state. Can be stably supported.

Further, a damper member for selectively blocking the flow path is provided on the air supply port and the exhaust port provided in the outdoor direction among the air supply port and the exhaust port provided on both sides of the upper region lp, respectively. Can be done.

Specifically, as shown in FIGS. 3 and 4, the first and second damper members 261,271 are provided on the first exhaust port 260 and the second air supply port 270, respectively, in the air cleaning mode. 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 air supply port 270 can be opened in the temperature controlled ventilation mode. The opening degree 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) can be further provided in the lower region lp of the temperature control device 200. The third damper member 281 can selectively shield the flow path through which the indoor air supplied from the ventilation device 100 detours in the lower region lp.

A detailed description of such an air purification mode, a temperature controlled ventilation mode, and a general ventilation mode will be disclosed with reference to FIGS. 5 to 7.

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

FIG. 5 shows an air flow path in a state where the ventilation device 100 and the temperature control device 200 of the present invention are operated in the air purification mode.

In the air cleaning mode, the first damper member and the second damper member of the upper region up are controlled to be in a closed state, and the third damper member 281 of the lower region lp is controlled to be in an open state, whereby the ventilation device. As the indoor air passing through the 100 circulates in the lower region lp, the contaminants can be filtered and supplied to the ventilator 100 through the upper region up.

For this purpose, the lower region lp of the temperature control device can be provided with 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 passing through. Further, 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 applies the phytoncide liquid to the indoor air, the outdoor air or the mixed air of the indoor air and the outdoor air passing through. Further, a phytoncide liquid injection unit 240 for injecting can be provided.

Phytoncide is a substance that plants spout or secrete to resist pathogens, pests, and molds. When exposed to phytoncide, stress is relieved, intestinal and cardiopulmonary functions are strengthened, and bactericidal action is also performed. Therefore, by injecting the concentrated liquid phytoncide liquid of phytoncide into the air flowing through the flow path in the form of a mist, the temperature controller, ventilation device (particularly, the area around the total heat exchanger or the blower fan) and the entire ventilation duct Can be sterilized or provided with the function of preventing bacterial growth.

The phytoncide liquid injection unit 240 can be controlled to be sprayed periodically or intermittently only on a predetermined schedule or condition, and the phytoncide liquid is replenished or the phytoncide liquid container is controlled by the control of the temperature control device. (Not shown) can be configured to be interchangeable.

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

Therefore, when the temperature of the outdoor air is too low or high, ventilation of the indoor air is unnecessary, but purification of the indoor air is necessary, as shown in FIG. 5, the temperature control device 200 of the present invention is used. It can operate in air purification mode.

In this case, when the temperature control device 200 is driven in the air purification mode, the exhaust of the indoor air and the supply of the outdoor air are unnecessary, so that all the damper members in the upper region lp are controlled to be closed. The damper member of the lower region lp can be controlled to be in an open state. Specifically, if the first damper member 261 and the second damper member 271 are controlled to be in a closed state and only the third damper member 281 is controlled to be in an open state, the ventilation device 100 is contaminated. Contaminants are removed from the indoor air by the filter unit 290 as it passes through the ventilation device 100, and the phytoncide liquid is injected from the phytoncide liquid injection unit 240 to perform antibacterial treatment, and then the second exhaust port 250 and the ventilation. It can be supplied indoors via the device 100.

Generally, the ventilation device 100 is also provided with filter portions 140a and 140b, but its performance is not sufficient and replacement is not easy, so that it is not sufficient as a means for blocking particulate matter.

However, as shown in FIG. 4, the temperature control device 200 of the present invention has a control port 202, which can be opened and closed so as to be able to approach the internal space of the lower region lp in the indoor direction lower than the ventilation device 100. Since the 203 is provided, it is easy to replenish the replacement phytoncide solution of the filter constituting the filter unit 290.

Since the lower region lp of the temperature control device 200 is lower than the ceiling and can easily approach the control ports 202 and 203, the maintenance and management of the filter unit 290 or the phytonchid liquid injection unit is performed rather than replacing the filter of the ventilation device 100. Is effective for reducing particulate matter contained in the ventilated air so as to eliminate the anxiety of users who hesitate to ventilate due to the increasingly severe particulate matter these days. Can provide a solution.

Further, the space between the control ports 202 and 203 may be provided with a storage space 201 for accommodating a phytoncide liquid supply unit, a control unit, or the like.

The indoor air that flows in through the upper region up and passes through the lower region lp is allowed to flow along the'∪'-shaped flow path, and is vertically'∪' for the treatment of the horizontally flowing air. By adding a glyphic flow path, the effect of minimizing the thickness or the horizontal width of the temperature control device can be obtained.

FIG. 6 shows an air flow path in a state where 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 required.

In the ventilation mode, the first damper member and the second damper member of the upper region up are controlled to the open state, and the third damper member 281 of the lower region lp is controlled to the closed state, whereby the ventilation device 100. The indoor air passing through the above region up passes through the upper region up of the temperature control device and is discharged to the outside, and the air supplied from the outside is supplied to the ventilation device 100 through the upper region up via the lower region lp. be able to.

As shown in FIG. 6, the indoor air that has been heat-exchanged while passing through the ventilation device 100 is supplied to the first air supply port 280 of the temperature control device 200, discharged to the outside through the first exhaust port 260, and is the outdoor air. Is supplied through the second air supply port 270, then filtered while passing through the internal space of the lower region lp, and after the phytonchid liquid is injected, the second exhaust port 250 and the total heat exchanger 130 of the upper region lp. Can be supplied indoors through a ventilator 100 equipped with.

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

Specifically, if the ventilation device 100 is driven in a state where the first damper member 261 and the second damper member 271 are controlled to be in an open state and only the third damper member 281 is controlled to be in a closed state, the ventilation device 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 is decontaminated by the filter unit 290, antibacterial treated by spraying the phytoncide liquid, and then supplied to the room via the second exhaust port 250 and the ventilation device 100. Can be done.

In this case, the outdoor air that flows in through the upper region up and passes through the lower region lp can form a'∪'shaped flow path.

FIG. 7 shows an air flow path in a state where the ventilation device 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 of the upper region up are controlled to be in a partially open state, and the third damper member 281 of the lower region lp is controlled to be in an open state or a partially open state. As a result, a 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 indoor air that has passed through the ventilation device 100 can pass through the upper region up and be discharged to the outside of the room.

All indoor air ventilation and decontamination are required, but if the temperature difference between the indoor air and the outdoor air is large and energy loss is expected to be large when operating in general ventilation mode, the temperature of the present invention. The regulator 200 can be driven in a temperature controlled ventilation mode.

When the temperature control device 200 is driven in the temperature control ventilation mode, the damper member in the upper region lp is controlled to be in a partially open state, and the damper member in the lower region lp is controlled to be in an open state or a partially open state. Can be done.

That is, if the ventilation device 100 is driven in a state where the first damper member 261, the second damper member 271 and the third damper member 281 are partially opened, the room flows into the temperature control device 200 through the ventilation device 100. A part of the air flows into the lower region lp of the temperature control device 200, and the remaining 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 open state, the air flowing in the lower region lp flows to the filter portion 290 side, and the second damper member 271 is also in an open state, so that it is outdoors. Air is supplied through the second air supply port 270, mixed with the room air described above, pollutants are removed by the filter unit 290, antibacterial treatment is performed by jetting the phytoncide liquid, and then the second exhaust port 250 and the ventilation device. It can be supplied indoors via 100.

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

In this case, each of the outdoor air, the indoor air, and the mixed air that flows in through the upper region up and passes through the lower region lp can form a'∪'shaped flow path.

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

In this way, when the temperature difference between the indoor and outdoor areas is large but ventilation is required, ventilation can be performed while reducing the air conditioning load in the indoor space, and air purification and antibacterial treatment can be performed at the same time.

Similarly, the indoor air, the outdoor air, and the mixed air thereof that flow in through the upper region up and pass through the lower region lp can form a'∪'shaped flow path.

As shown in FIGS. 5 to 7, the present invention controls the damper unit and the phytoncide liquid injection unit 240 to drive the ventilation device 100 in various modes without a separate blower fan or the like. Can be done.

By such a method, it is possible to minimize the air conditioning load by mixing the indoor air to be exhausted and the outdoor air to be supplied to alleviate the indoor thermal shock while performing ventilation in the extreme cold or hot weather. can.

Further, even in the process of mitigating the indoor thermal shock and minimizing the air conditioning load, the indoor air purification and the antibacterial treatment can be simultaneously performed so that the mixed air passes through the filter unit 290 and the phytoncide liquid injection unit.

This specification has been described with reference to preferred embodiments of the invention, but those skilled in the art will not deviate from the ideas and areas of the invention described in the claims described below. The present invention could be modified and modified in various ways. Therefore, any modified practice should be considered to be within the technical scope of the invention, including the components of the claims of the invention.
