Through this, in the ventilation air purifier 100 according to an embodiment of the present invention, even if dew condensation occurs inside the heat exchanger 140 during the heat exchange between indoor air and outdoor air through the heat exchanger 140 , Condensation can be prevented by allowing relatively high-temperature air to pass through the heat exchanger 140 for a predetermined period of time.

For this reason, it is possible to prevent in advance the propagation of bacteria such as mold inside the heat exchanger 140 .

As a non-limiting example, when the ventilation air purifier 100 according to an embodiment of the present invention is driven through a user's manipulation as shown in FIG. 13 , the control unit 160 is configured as a first step (St1). For ventilation, both the first blower 120 and the second blower 130 may be operated.

Accordingly, the outdoor air may be sucked in from the outside through the driving of the first blower 120 and then discharged to the indoor space through the heat exchanger 140 , and the indoor air is driven by the second blower 130 . After being sucked from the indoor space through the heat exchanger 140, it may be discharged to the outside.

Then, when a signal for turning off or temporarily stopping the driving of the ventilation air purifier 100 is input to the control unit 160 through a user's manipulation, the control unit 160 controls the outdoor air temperature as a second step (St2). (To) and the temperature (Ti) of the indoor air can be compared.

Through this, the control unit 160 may selectively drive any one of the first blower 120 and the second blower 130 as the third step (St3) and change the other to the OFF state.

That is, if the temperature To of the outdoor air is relatively higher than the temperature Ti of the indoor air through the second step (St2), the control unit 160 turns on the operation of the first blower 120. While maintaining, the operation of the second blower 130 may be changed to an off state.

On the other hand, if the temperature To of the outdoor air is relatively lower than the temperature Ti of the indoor air through the second step St2, the control unit 160 turns off the operation of the first blower 120. While changing, the operation of the second blower 130 may be maintained in an on state.

Through this, the relatively high temperature air among the indoor air and the outdoor air may be additionally introduced into the heat exchanger 140 for a predetermined period of time. For this reason, the inside of the heat exchanger 140 may be dried using the heat of relatively high temperature air, thereby preventing condensation from occurring inside the heat exchanger 140 .

Then, as a fourth step (St4), the control unit 160 may stop the operation of the blower that is in an on state selectively among the first blower 120 and the second blower 130 . That is, when the operation of the first blower 120 is in the on state and the operation of the second blower 130 is in the off state, the operation of the first blower 120 is maintained while the operation of the second blower 130 is maintained in the off state. The operation may be changed to an off state, and when the operation of the first blower 120 is in the off state and the operation of the second blower 130 is in the on state, the operation of the first blower 120 is maintained in the off state. The operation of the second blower 130 may be changed to an off state. Through this, the ventilation air purifier 100 according to an embodiment of the present invention may be changed to an off state or a pause state.

On the other hand, if the filter member 150 applied to the ventilation air purifier 100 according to an embodiment of the present invention can remove fine dust contained in the air, all of the known various filter members can be applied, but replace It can be configured to increase the cycle, increase the removal efficiency, and lower the pressure loss.

In addition, the filter member 150 may disable or remove an antivirus such as Corona 19 from outdoor air flowing into the room by adding an antiviral function.

In addition, an antibacterial function may be added to the filter member 150 .

Accordingly, when the ventilation air purifier 100 according to an embodiment of the present invention is operated, the outdoor air in a state in which pollutants such as yellow dust and fine dust are filtered while the indoor air is discharged as described above is introduced into the room. can Through such ventilation, the concentration of carbon dioxide in the indoor air can be lowered and the indoor air can be maintained in a comfortable state because pollutants existing in the room can be discharged.

In addition, since outdoor air in a state in which an antivirus such as Corona 19 is disabled or removed through the filter member 150 can be introduced into the indoor space, the occurrence of diseases and disease transmission due to viruses can be prevented in advance.

On the other hand, the filter member 150 for filtering outdoor air is configured to inhibit the growth of bacteria, mold, viruses, etc., thereby preventing contamination of the heat exchanger while preventing bacteria and viruses from entering the room.

To this end, the filter member 150 may include a porous first member 151, a porous second member 152 and a third member 153 electrostatically treated as shown in FIGS. 7 to 9 . can

The first member 151 is a porous member that has been electrostatically treated, and may be a filter medium through which outdoor air primarily passes, and the first member 151 filters fine dust, dust, etc. contained in the air using electrostatic force. can do. For example, the first member 151 may be a known nonwoven fabric, preferably a melt blown nonwoven fabric.

Here, the electrostatic treatment may be performed on the entire area of the first member 151 , but may be processed only on a partial area of the total area of the first member 151 , and in manufacturing a typical electrostatic treatment filter A known method used may be appropriately employed.

In addition, in the first member 151, the diameter and basis weight of the fiber can be adjusted according to the purpose, and in order to guarantee improved filtration performance and durability, the first member 151 is a fiber having a diameter of 1 to 10 μm. may include, and the basis weight of the first member 151 may be 15 to 50 g/m 2 , and in another example, the basis weight may be 20 to 35 g/m 2 . In addition, the average pore diameter of the first member 151 may be 20 μm or less, and in another example, 10 μm.

If the average pore diameter of the first member 151 is excessively small, air permeability may decrease and pressure loss may increase. Conversely, when the average pore diameter of the first member 151 is excessively large, filtration efficiency may be reduced.

In addition, when the average diameter of the fibers forming the first member 151 is excessively small, air permeability may decrease and pressure loss may increase. Conversely, when the average fiber diameter of the first member 151 is excessively large, filtration efficiency may be reduced.

In addition, if the basis weight of the first member 151 is excessively low, the filtration efficiency may be lowered as the deviation increases, or a uniform filtration efficiency may not be expressed. Conversely, if the basis weight of the first member 151 is excessively large, air permeability may be reduced and pressure loss may increase.

Meanwhile, the fibers forming the first member 151 may include a synthetic polymer component selected from the group consisting of polyester, polyurethane, polyolefin and polyamide, or a natural polymer component including cellulose.

The second member 152 may secondarily filter the air that has passed through the first member 151 .

To this end, the second member 152 may be a nanofiber web in which nanofibers are accumulated, and the nanofiber web may be in which nanofibers are accumulated in a three-dimensional network structure.

For example, the second member 152 may include a known fiber-forming component capable of forming nanofibers, and preferably, the fiber-forming component may be a component capable of electrospinning.

The pore diameter of the second member 152 may have a size capable of physically filtering fine dust of PM2.5 or less, and the second member 152 may be configured to prevent a decrease in the flow rate of passing air. Euros may be included.

The second member 152 is configured to form the filter member 150 together with the above-described first member 151 to compensate for the problem of reduction in collection efficiency due to static electricity that may occur in the electrostatically treated first member 151 . And it can maintain the designed filtration efficiency even for a long time.

That is, the electrostatically treated first member 151 uses electrostatic force to adsorb dust to the fiber surface, and as time passes, the electrostatic force decreases. Accordingly, when the filter member 150 is configured using only the electrostatically treated first member 151 , the filtration efficiency of the filter member 150 decreases as time passes, so there is a problem that the replacement cycle is very short.

However, when the filter member 150 is composed of the first member 151 and the second member 152 subjected to electrostatic treatment, the reduction in collection efficiency is small compared to the filter member composed only of the first member 151, Even after several months, the collection efficiency can be maintained at more than 95% of the initially designed value.

Meanwhile, the second member 152 may have an antiviral function by further including an antiviral component in the nanofiber.

For example, the second member 152 may be provided with an antiviral coating layer on the nanofiber web, and the antiviral coating layer may include an antiviral component.

Here, the antiviral component may include an antiviral fusion protein, and the antiviral fusion protein may be formed by binding an antiviral motif to an adhesive protein. The antiviral motif may be a motif that functions to block infection by inhibiting the proliferation of the virus, annihilating the virus itself, or participating in the mechanism of the host being infected by the virus.

10 and 11 , the antiviral motif may have a function of directly or indirectly destroying the outer membrane, which is a protective layer of the virus. In addition, when the virus infects a host cell, the antiviral motif directly or indirectly destroys a protein that binds to a receptor of a host cell (ex. the spike protein of coronavirus), or directly or indirectly disables the protein. can have

Here, the direct or indirect meaning may mean that the antiviral motif directly performs the corresponding function or is ultimately involved in the beginning or intermediate process in performing the corresponding function.

The antiviral motif may be used without limitation as long as it is a known motif known to have antiviral effects such as extinction and inactivation of the aforementioned virus.

As a non-limiting example, the antiviral motif is any one peptide selected from the group consisting of the amino acid sequence of SEQ ID NO: 1 to SEQ ID NO: 7, a peptide to which one or more amino acid sequences selected from the group are linked, or one selected from the group It may be a peptide comprising more than one amino acid sequence as a basic sequence.

Here, the motifs according to SEQ ID NOs: 1 and 2 may be useful for SARS coronavirus, the motifs according to SEQ ID NOs: 3 to 7 may be useful for influenza A virus, and the motif according to SEQ ID NO: 7 may also be useful for HSV have.

In addition, the antiviral motif may be, for example, a peptide having 3 to 100 amino acids, more preferably 3 to 20 amino acids.

In addition, the virus targeted by the antiviral motif is not limited in the case of a known virus, and non-limiting examples thereof include JV, HSV, HIV, IPNV, VHSV, SHRV, HCMV, IAV, Japanese encephalitis virus, Ebola virus, It may be rhinovirus, adenovirus, measles virus, hepatitis B virus, influenza A and the like.

The above-described antiviral motif may be provided in the nanofiber web by itself without forming a fusion protein, but it may be difficult to fix only the antiviral motif in the nanofiber web for a long time. In order to solve this problem, in the present invention, the antiviral motif can be implemented in the form of a fusion protein combined with a junction protein, and it can be provided on the fiber web or the surface of the fiber forming the fibrous web.

The adhesive protein may function as an adhesive component that provides adhesion between the antiviral motif and the fibrous web or the fiber surface forming the fibrous web. In addition, the binding between the antiviral motif and the adhesive protein may be a covalent bond, and more specifically, the carboxy terminus, amino terminus, or both carboxy terminus and amino terminus of the adhesive protein may be bound by a peptide bond.

On the other hand, the antiviral motif and the adhesion protein can be combined through a known method, for example, can be prepared through a recombinant protein production method using E. coli. Meanwhile, the adhesive protein and the antiviral motif may be directly covalently bonded, but the present invention is not limited thereto and may be indirectly coupled between the adhesive protein and the antiviral motif by adding a third material as a spacer.

In addition, the adhesive protein may be used without limitation in the case of a protein having a known adhesion function, but may be, for example, a mussel-derived adhesion protein, and a known adhesion protein commonly referred to as a mussel-derived adhesion protein may be used without limitation. have. Preferably, the adhesive protein may be any one protein selected from the group consisting of the amino acid sequence of SEQ ID NO: 8 to SEQ ID NO: 21, or a protein to which one or more amino acid sequences selected from the group are linked.

In addition, the adhesive protein is a coating layer in the form of aggregates formed by reacting with an aggregation inducing component including a carbodiimide coupling agent and a hydroxy succinimide-based reactant, which may be further contained in the coating composition to be described later. Through this, the antiviral motif can be fixed on the fiber web or the fiber surface forming the fiber web with improved adhesive strength. In addition, by preventing or minimizing the disabling of the antiviral motif for a long time at room temperature, such as decomposition, denaturation, etc., the antiviral performance can be maintained for a long time, and storage stability and friction fastness can be improved.

On the other hand, the adhesive protein may contain a guiding moiety in order to express more improved fibrous web or adhesion properties with the fiber surface forming the fibrous web. Mussel adhesive proteins are known to have adhesive properties, but as a result of the study by the present inventors, when these adhesive proteins are used as they are, they show no or insignificant level of adhesive (or adhesion) properties, so it may be difficult to fix the antiviral motif on the surface of the substrate. .

In order to improve this, it can be modified to contain a guide moiety in the adhesion protein, and in this case, improved adhesion performance can be expressed. The modification may be performed by appropriately using a known method by modifying some or all of the tyrosine residues contained in the adhesion protein with a guide residue. For example, the modification may be performed using an enzyme, and the enzyme may be, for example, tyrosinase.

As for the method of modifying the tyrosine residue into the dopa residue using tyrosinase, the antiviral fusion protein having an adhesive protein was prepared with 25-100 mM ascorbic acid, 20-100 mM sodium acetate, 20-100 mM sodium borate. After dissolving in a buffer solution to a concentration of 0.01 ~ 10 mg/ml, oxygen is injected for 10 ~ 1 hour to saturate the oxygen in the solution, and then tyrosinase is added to a final concentration of 10 ~ 50 μg/ml. After mixing and stirring under oxygen conditions for 30 minutes to 2 hours, the reaction is terminated by adding acetic acid to a final concentration of 2 to 10%, desalting and concentration of the finished reaction solution with 1 to 10% acetic acid solution, followed by freeze-drying Through this process, a dopa-modified antiviral fusion protein in powder form can be obtained.

The antiviral fusion protein containing the waveguide moiety prepared by the above-described method can be easily fixed on the fiber web or the fiber surface forming the fiber web without other adhesive components. Inadvertent chemical reaction between the ingredient and the antiviral motif, or deterioration or inability of activity due to physical blocking can be prevented.

In addition, the antiviral component may further include a heterogeneous substance having an antiviral function in addition to the above-described antiviral fusion protein. The heterogeneous material may be a known organic material or inorganic material. For example, the heterogeneous material may be an inorganic material in which a substituent having proton donating or proton water solubility is disposed on a surface contacted by a virus, and specific examples include a phosphate compound of a titanium group element such as zirconium phosphate, hafnium phosphate, titanium phosphate, aluminum phosphate , inorganic phosphoric acid compounds such as hydroxyapatite (phosphate mineral); inorganic silicic acid compounds such as magnesium silicate, silica gel, aluminosilicate, sepiolite (hydrous magnesium silicate), montmorillonite (silicate mineral), and zeolite (aluminosilicate); It may be alumina, titania, hydrous titanium oxide, or the like. Alternatively, the heterogeneous material may be a salt containing a metal such as silver or an ion thereof.

The above-described antiviral component may be implemented with an antiviral coating layer by processing the antiviral coating composition on the fiber web or fibers forming the fibrous web. At this time, the fibrous web implemented using the fiber having the antiviral coating layer treated with the antiviral coating composition on the fiber may be implemented by a conventional nonwoven fabric manufacturing process.

The antiviral coating composition may further include a solvent or stabilizing buffer solution for dissolving the antiviral component in addition to the antiviral component including the above-described antiviral fusion protein. The solvent may be water and/or an organic solvent, and 20 to 100 mM Tris or sodium hydrogen carbonate buffer solution having a pH of 8 to 8.5 may be used.

In addition, the above-described antiviral fusion protein may be contained in the coating composition at a concentration of 0.001 to 1 mg/ml, as another example, 0.001 to 0.1 mg/ml, and if contained at a high concentration, antiviral properties may be improved, but , it may block the pores of the fibrous web to which the coating composition is applied, which may be undesirable if the pores of the fibrous web are to be maintained.

On the other hand, the antiviral coating composition comprising the antiviral fusion protein containing the above-described guidepa moiety can improve the adhesion of the implemented antiviral coating layer, but additional cost, time and effort are required according to the modification. The antiviral coating composition according to another embodiment may further include an aggregation-inducing component including a carbodiimide coupling agent and a hydroxy succinimide-based reactive agent in the coating composition without modifying the adhesive protein.

The aggregation-inducing component is a material for introducing the antiviral fusion protein to the surface of the substrate, and in case the antiviral fusion protein is treated alone or on the surface of the fiber constituting the fibrous web using a conventional method, the antiviral fusion protein It is possible to improve the adhesion between the coating layer and the surface of the.

Specifically, the aggregation-inducing component aggregates the antiviral fusion protein into granules, and the antiviral coating layer can be implemented in such a way that these granules are adsorbed to the surface of the substrate to form an aggregate. The coating composition using the aggregation-inducing component can enhance the adhesion of the antiviral fusion protein, and it can stably maintain its shape and activity even under changes in external temperature or humidity, so it has excellent storage stability and friction fastness, and antiviral The effect can last for a long time.

On the other hand, the antiviral coating layer implemented through the antiviral coating composition containing the aggregation inducing component may include a carbodiimide-based compound. It may remain in the antiviral coating layer through bonding to a hydroxyl group, a sulfone group, or the like.

On the other hand, the granular form in which the antiviral fusion protein is aggregated due to the aggregation inducing component is difficult to see as due to a specific chemical bond between the fusion proteins, for example, an amino bond between a carboxyl group and an amine group by a conventionally known carbodiimide coupling agent. , This is because the adhesive protein, for example, a plurality of hydroxyl groups and sulfone groups included in the mussel-derived adhesive protein, can also react with the carbodiimide coupling agent. Therefore, the granular form formed by the antiviral fusion protein according to the present invention having a plurality of reaction sites is difficult to be regarded as due to a specific reaction and a chemical bond resulting therefrom. can be seen as a result of

The carbodiimide coupling agent may be used without limitation in the case of a coupling agent that allows the antiviral fusion proteins to bind to each other, for example, 1-[3-(dimethylamino)propyl]-3-ethylcarboimide hydrochloride (EDC) or N,N'-dicyclohexylcarboimide (DCC).

In addition, the reactive agent is provided to prevent the antiviral fusion protein in a coupled state with carbodiimide from being hydrated, thereby increasing the efficiency of antiviral fusion proteins aggregating with each other. For example, N-hydroxysuccin is It may be one of imide (NHS) and N-hydroxysulfosuccinimide (Sulfo-NHS), or a mixture thereof.

The aggregation inducing component may include the carbodiimide coupling agent and the reactant in a weight ratio of 1:0.5 to 20. If they are not included in an appropriate ratio, it is difficult to achieve the desired effect of the present invention, and there is a fear that the durability of the implemented antiviral coating layer and the activity of the antiviral motif may be reduced.

In addition, the aggregation-inducing component may further include sodium acetate, phosphate buffer or MES buffer as an active ingredient to improve reactivity. In this case, the active ingredient may be included in an amount of 1 to 100 parts by weight based on 100 parts by weight of the carbodiimide coupling agent.

In addition, the above-mentioned aggregation component to the coating composition may be added in a liquid phase dissolved in a solvent, in which case water or an organic solvent may be used as a solvent, preferably water and/or ethanol may be used, and coating In terms of increasing the volatilization rate of the solvent in the composition, ethanol may be used as a solvent. When vaporization of the solvent is slow after treatment of the coating composition, it may be difficult to form an antiviral coating layer with a desired content and thickness, as the coating composition flows from the fiber web or the fiber surface forming the fiber web.

On the other hand, when the coating composition further contains an aggregation inducing component, a reaction between the antiviral fusion protein and the aggregation component may be induced until the coating composition is treated on the fiber web or the surface of the fiber forming the fiber web, and if the reaction is the target If the fiber web or the fiber surface forming the fiber web is treated after being excessively advanced beyond one level, it may be difficult to form an antiviral coating layer. Accordingly, it is preferable that the coating composition further include a delay component capable of delaying the reaction between the antiviral fusion protein and the aggregation inducing component, or the coating composition is stored under conditions capable of delaying the reaction, for example, a low temperature condition.

Alternatively, in order to further improve storage stability, the antiviral coating composition may be composed of a two-component coating composition comprising a first liquid containing an antiviral component and a second liquid containing the aggregation component. In this case, the first liquid may include water as a solvent, and the second liquid may include ethanol.

In addition, the antiviral coating composition may further include an oxidizing agent such as sodium periodate and hydrogen peroxide, and through this, it may be easier to achieve the object of the present invention.

As another example, the second member 152 may further contain an antiviral component in the nanofiber to perform an antiviral function. In this case, the antiviral component may include a surfactant, and specifically, a surfactant in which a functional group included in the surfactant binds to a virus to express antiviral performance may be used.

As a specific example, a polyoxyalkylene alcohol type nonionic surfactant may be used. Specific examples of the polyoxyalkylene alcohol type nonionic surfactant include polyoxypropylene glycol, polyoxyethylene glycol, polyoxyethylene polyoxypropylene glycol, polyoxyethylene alkyl ether, polyoxyethylene polyoxypropylene alkyl ether, acetylene glycol or acetylene alcohol. In addition, anionic surfactants such as C8 to C22 alkyl sulfonates and/or alpha sulfonated carboxylic acids or esters thereof, specifically linear alkyl benzene sulfonic acids, can also be used, in addition to cationic, Amphoteric surfactants may also be used.

The third member 153 may be a porous member performing a supporting function of the filter member.

The third member 153 may be disposed between the first member 151 and the second member 152 , but is not limited thereto, and may be disposed on one surface of the second member 152 .

In this case, the third member 153 is not particularly limited as long as it is a porous member that normally functions as a support.

As an example, the third member 153 may be a woven fabric, a knitted fabric, or a non-woven fabric, and as a non-limiting example, the third member 153 may be a thermal bonding non-woven fabric.

However, the material of the third member 153 is not limited thereto, and may include synthetic fibers selected from the group consisting of polyester, polypropylene, nylon and polyethylene.

Meanwhile, the filter member 150 may further have an antibacterial function. With this in mind, the filter member 150 may further include a fourth member 154 disposed between the first member 151 and the third member 153 as shown in FIG. 9 .

Here, the fourth member 154 may be formed including a known component having antibacterial properties, but preferably may be formed of a fiber containing silver that exhibits antibacterial properties.

The silver-containing fiber may be a silver wire made of silver alone, a metal wire containing other metals such as copper other than silver, or a ply-twisted yarn in which a silver wire and/or a metal wire containing silver and a conventional non-metal fiber are braided. have.

When describing a metal wire containing other metals such as copper, it may be linearly formed by mixing a metal other than silver in a non-solid state with silver, that is, in a non-solid state, ie, silver and non-alloy state. When a metal other than silver is mixed with silver in a non-solid state, the silver and the other metal may be arranged such that silver and other metal occupy a predetermined area regularly or irregularly in a single linear region, For example, it may have a double structure in which a layer is formed by enclosing silver on the outside of the copper wire.

In this case, the copper wire may impart excellent flexibility to the silver wire, and the surrounding silver may have an average thickness of 3 to 3200 nm, and preferably, an average thickness of 5 to 3000 nm. If the average thickness of the surrounding silver is less than 3 nm, it is easy to manufacture so that copper, which is the central metal, is exposed to the outside, so that the antibacterial function may be reduced, and the silver may be detached from the silver wire, thereby further reducing the antibacterial function. In addition, when the average thickness of the surrounding silver exceeds 3200 nm, the flexibility of the silver wire may decrease.

Next, a description of the ply-twisted yarn in which a silver wire is plied with a non-metallic conventional fiber is described. For the silver wire and the conventional fiber, a known manufacturing method in the field of textiles in which two types of fibers are plied, and a known arrangement structure of two types of fibers are appropriately used. It may be a ply-twist yarn implemented by employing it.

In this case, the silver wire used may be a wire made of only silver or a metal wire containing silver and other metals. For example, the ply-twisted yarn is a yarn having a triple structural cross section including a core yarn, a first covering yarn including a silver line surrounding the core, and a second covering yarn surrounding the outside of the first covering yarn surrounding the core yarn can

The core and second covering yarns may be used without limitation as long as they are fibers that can be used to improve the flexibility and elasticity of the ply-twisted yarn, and preferably, any one or more selected from natural fibers and synthetic fibers may be used, and more preferably, poly Ester-based fibers may be used.

In addition, the core yarn and the second covering yarn may be formed of a mono yarn or a plurality of filament yarns, and preferably a fiber formed of a plurality of filament yarns.

In addition, the screening and second covering yarns may be used without limitation as long as they are fibers of fineness commonly used in the art, and preferably each independently may have a fineness of 20 to 100De' (denier), more preferably The fineness may be 30 ~ 75De'.

If the fineness of the screening and the second covering yarn is independently less than 20De', durability and antibacterial performance due to the single yarn of the silver wire may be reduced, and if the fineness exceeds 100De', elasticity may be reduced.

In addition, the second covering yarn may be twisted at a twist number of 350 to 1100 TPM, preferably twisted at 450 to 1000 TPM, and may be included in the ply-twisted yarn. If the number of twists of the second covering yarn is less than 350 TPM, the durability and antibacterial performance according to the single yarn of the silver wire may be deteriorated. In addition, when the number of twists exceeds 1100 TPM, elasticity and flexibility of the third member may be reduced, and as the area of the silver wire exposed to the surface decreases, the antibacterial performance may be relatively reduced.

In addition, the fourth member 154 may be a woven fabric, knitted fabric, nonwoven fabric, or mesh sheet implemented to have a porous structure including the aforementioned silver wire, silver-containing metal wire, and/or ply-twisted yarn. In this case, the woven fabric, knitted fabric, non-woven fabric or mesh sheet may further include natural fiber and/or synthetic fiber that does not contain a silver wire.

Such a filter member 150 may be implemented as a pleated filter in which peaks and valleys are repeatedly formed so as to increase the filtration area.

On the other hand, when the filter member 150 is implemented as a pleated filter, the filter member 150 may be bent so that the height h of the ridge or valley is 5 to 55 mm, preferably It may be bent so that the height of the peak or the valley has a size of 10 to 50 mm.

If the height of the peak or valley is less than 5 mm, the filtration area may be reduced, so that the filtration efficiency may be lowered and the pressure loss may be increased. In addition, when the height of the ridge or trough exceeds 55 mm, the adjacent ridge and ridge or trough and trough may adhere to each other, thereby reducing the filtration area, and when the pressure is high, the ridge or valley may be deformed. Here, the height of the ridge or valley means a height difference between adjacent ridges and valleys.

In addition, the filter member 150 may be bent to form 70 to 95 peaks per 300 mm in length, and the size of the filter member is 1.3 to 8.5 m per 300 mm of the installation space in which the filter member is installed. A filter element having a length may be used.

Through this, the filter member 150 can increase the specific surface area compared to the total size of the installation space, so that the removal efficiency is excellent, the pressure loss can be lowered, and the reduction of the removal efficiency can be prevented.

Here, the filter member 150 may be directly coupled to one side of the heat exchanger 140 .

Alternatively, the filter member 150 may further include a filter frame 155 disposed to surround the rim as shown in FIG. 7 , and the filter member 150 is passed through the filter frame 155 . It may be coupled to one side of the heat exchanger 140 .

Although one embodiment of the present invention has been described above, the spirit of the present invention is not limited to the embodiments presented herein, and those skilled in the art who understand the spirit of the present invention can add components within the scope of the same spirit. , changes, deletions, additions, etc. may easily suggest other embodiments, but this will also fall within the scope of the present invention.
