Air conditioning is a concept that includes a cooling device (air conditioner) that cools and circulates air and a heating device (heater) that heats and circulates air. The indoor air is sucked in through the main body, the air sucked in is cooled or heated, and then discharged back into the room through the exhaust port.

Normally, air conditioning and heating devices are manufactured and sold as separate products, but recently, an air conditioning and heating device capable of simultaneously cooling and heating with one device is used. The air conditioner used in this specification may be understood as a concept including a cooling device, a heating device, and a cooling/heating device.

A detachable filter is built into the inlet side of the main body of the air conditioner to filter out foreign substances such as dust contained in the air that is sucked in. Such a filter is usually a mesh net or net shape made of plastic (PP).

Recently, interest in indoor air quality has increased, so precision filters (such as HEPA filters or nano filters) used in air purifiers are also used in air conditioners and heating devices, but in this case, the cost is high and the hassle of cleaning or replacing the filter It is common to purchase and use a separate air purifier.

On the other hand, the following prior art documents disclose an external filter attached to the outer surface of an air inlet of an air circulator. In this external filter, a filter member such as a HEPA filter or an activated carbon filter is sucked into a plate-shaped support member in which a plurality of suction holes are formed. It has a structure in which the inner surface of the hole or one side of the support member is tightly provided by thermal fusion, and the other side of the support member (the side facing the suction port) is provided with an adhesive.

However, such a prior art has a problem in that manufacturing cost is increased because a filter member such as a relatively expensive HEPA filter or an activated carbon filter is applied and the filter member must be fixed to the support member by thermal fusion.

In addition, since the plate-shaped support member is applied, it can be relatively easily attached to a stand-type air conditioner and can be robust, but when applied to a wall-mounted air conditioner with a curved inlet shape, it may be difficult to attach and not sturdy.

On the other hand, Dunaliella salina, a natural microalgae, is a eukaryotic organism belonging to green algae that performs photosynthesis. It exhibits a high salt adaptation range. Thus, Dunaliella salina is mainly found in places with low nitrogen content, strong sunlight and high salt concentrations.

In addition, Dunaliella salina contains natural beta-carotene. When the culture environment deteriorates, such as irradiation with strong light, beta-carotene is synthesized in large quantities to protect chlorophyll a, an important chlorophyll in photosynthesis, and grows under the cell wall. It is known to form a beta-carotene film on They accumulate beta-carotene (β-Carotene) in the cells in this way and turn yellow-green to orange. Therefore, Dunaliella salina is known as a marine microalgae that can be used for various purposes such as health food and medicine.

Beta-carotene (β-Carotene), which Dunaliella salina accumulates, is a carotenoid-based red pigment and is contained in a large amount of red-colored green vegetables such as carrots and tomatoes. Beta-carotene is used by being added to food due to its unique color and efficacy, and is widely used as an anticancer agent, an antioxidant related to skin aging, a skin disease treatment agent, and an antibacterial agent.

however. Despite the usefulness of beta-carotene, it is difficult to mass-produce and its content is limited even in green vegetables, so its production is not easy.

Recently, studies have been conducted to utilize Dunaliella salina and beta-carotene for various purposes such as health food and medicine. Accordingly, a method for culturing Dunaliella salina and a method for separating and refining beta-carotene from Dunaliella salina have been conducted. There are many reports about etc.

Therefore, after extracting the mixture of rice husk, silica mixture, and Dunaliella salina powder, adding a catalyst and aging it, coating or applying the filtered mixture on a nonwoven fabric and heat-treating it, it is possible to improve the amount of adsorption of heavy metals and carbon dioxide as well as antibacterial properties. Since the adsorption and antibacterial mixed solution coated or applied on the non-woven fabric filter has antiviral and adsorption power, the air sucked into the air conditioner is antibacterial and deodorized, and only purified air is supplied to the air conditioner and heating or cooling air is safely supplied indoors. It can be supplied to the pulverized silica together with water glass and a phytoncide solution for odor removal, and fried like a puff pastry using an industrial microwave oven to make it porous, and then calcium carbonate and red clay are added to prepare a silica mixture. KNO 3 , KH ₂ PO ₄ , FeSO 4 7H 2 0 and KNO ₃ , KH 2 PO 4 , FeSO ₄ 7H ₂ 0 and By transplanting and culturing Dunaliella salina in the Dunaliella salina culture medium composition optimized for the cultivation of Dunaliella salina prepared by adding MnSO ₄ H ₂ 0, it increases the growth rate of Dunaliella salina and beta There is an urgent need to develop a method for manufacturing a nonwoven fabric filter for air conditioners having a heavy metal, carbon dioxide adsorption and antibacterial function capable of increasing the content of carotene and a nonwoven fabric filter for air conditioners manufactured by the manufacturing method.

Here, the rice hull liquid is obtained by heating and carbonizing the rice hull and then liquefying it. When this rice hull goes through the process of carbonization, it creates countless holes like fine honeycombs, and its surface area is more than 200 pyeong per 1g, and it has excellent adsorption and breathability because it is in the form of rice hull itself. In addition, since the structure is dense and has many pores, it selectively absorbs harmful substances. That is, as the cell wall of the rice hull is burned, numerous fine pores are formed, and these pores can selectively absorb harmful viruses or toxins by exerting strong adsorption.

In addition, the rice hull can be prepared by removing impurities such as soil, sand, stone powder, etc. present on the surface by blowing air or washing several times in running water so as not to affect the carbonization and liquefaction processes to be described later. It is okay to grind and prepare with any equipment selected from ball mill, attrition mill, jet mill, rotary mill, and vibration mill. will be.

In addition, the rice hull from which impurities have been removed can be heated to 600 to 1000 ° C, preferably 750 to 850 ° C to carbonize the rice hull to remove woody substances such as cellulose. If the carbonization temperature is less than 600 ° C, cellulose, which is a fiber may be difficult to remove, and if it exceeds 1000 ° C., mineral components may be denatured.

In addition, the carbonized rice hull can be liquefied by applying pressure, preferably 5KG, under conditions of 50 to 300 ° C, preferably 100 to 200 ° C, and if the temperature is less than 50 ° C, it may be difficult to extract the active ingredient.
