Description

TECHNICAL FIELD

[0001] The utility model relates to air conditioning design field, concretely relates to a water cooling filter air conditioner. BACKGROUND

[0002] The compressor of the traditional air conditioner is arranged in the outdoor unit, and needs to be connected with the indoor unit through copper pipes after refrigeration.

[0003] At present, the compressor of the new air conditioner is arranged in the indoor unit, and only PVC water pipes are used to connect the indoor unit and the outdoor unit, without copper pipes. After refrigeration, the medium is heated and transmitted to the outdoor unit for cooling. The medium also has many kinds, and some of them are easy to increase impurities during the transmission to the outdoor unit for cooling, thereby producing peculiar smell. Moreover, more problems may be caused, such as pollution of the indoor unit, influence on heat transfer efficiency, local aging and damage of the heat exchanger, abrasion and corrosion of the rotating parts such as the fan blades and the water pump impeller, corrosion of the corrosive impurities, reduction of the heat exchange efficiency due to the impurity blockage, and problems of the compressor burden.

[0004] When the medium is tap water, impurities are mixed in the tap water during the circulation and the spraying process, and peculiar smell is produced. Therefore, it is urgent to invent a water cooling filter air conditioner, so as to solve the above problems and improve the use experience of the air conditioner. CONTENT OF THE UTILITY MODEL

[0005] One of the purposes of the utility model is to provide a water cooling filter air conditioner in view of the deficiencies of the prior art, as described in the background.

[0006] To solve the above technical problems, the application adopts the following technical scheme:

[0007] The water cooling filter air conditioner comprises an outdoor unit assembly, a water tank, a filter assembly, a spraying assembly and a ventilation part. The water tank is arranged at the lower part of the frame, and the side of the water tank is provided with a water supplement opening, a water inlet opening, a water outlet opening and a water overflow opening. The water supplement opening is connected with a water source, and the water from the water source enters the water tank through the water supplement opening. The water inlet opening and the water outlet opening are connected with the indoor unit. When the water level in the water tank is higher than the water overflow opening, the water overflows from the water overflow opening. The filter assembly is arranged on the water tank and comprises a support, a second filter and a first filter arranged in sequence. The second filter has a fiber structure, and the first filter has a mesh structure. The spraying assembly comprises a water suction part and a water spraying part. The water suction part sucks water from the water tank, and the water sprayed by the water spraying part is filtered by the filter assembly and then enters the water tank. The ventilation part is arranged on the side of the frame. The filter assembly is mainly used to filter the water sprayed by the spraying assembly, so that a better filtering effect is achieved. The high-temperature cooling circulating water is delivered to the upper part of the outdoor unit of the water cooling filter air conditioner. Under the action of the evaporative water curtain combined with the ventilation part, the high-temperature water becomes normal-temperature water, and then flows through the indoor unit again, so as to reduce the temperature of the refrigerant under high pressure and high temperature, and form a reciprocating circulation system.

[0008] Further, the support is a perforated stainless steel structure, the second filter is filter cotton, and the first filter is a dust screen.

[0009] Further, the first filter is a dust screen in a mesh structure containing mesh holes.

[0010] Further, the first filter is a dust screen in a mesh structure containing mesh holes.

[0011] Further, the first filter is a dust screen in a mesh structure containing mesh holes.

[0012] Further, the second filter is a gradient density fiber filter cotton, which is divided into three layers from top to bottom: a polypropylene melt-blown cotton layer, a glass fiber cotton layer, and a hydrophobic modified non-woven fabric layer.

[0013] Further, the water tank is provided with a lower water level limit, and when the water level is lower than the lower water level limit, water enters the water tank from the water supplementing port.

[0014] Further, the water spraying element is arranged at the upper portion of the rack.

[0015] As a further improvement, the support is a drawer-shaped structure with a length of 500-1000 mm, a width of 400-900 mm, and a height of 10-50 mm.

[0016] As a combined improvement, the support is two or more pieces.

[0017] The beneficial effects of the present application are as follows:

[0018] 1. Can block impurities. When the evaporative cooling energy-saving air conditioner outdoor unit is running, it will suck in the surrounding air. Dust, sand, willow catkins, hair and other suspended particles in the air, as well as scale, rust and other substances that may exist in water, if they enter the air conditioner indoor unit, they will gradually accumulate. After installing the filter device, the fine structure of the filter screen can effectively intercept these particulate pollutants, prevent them from entering the indoor unit, and ensure the cleanliness of the air and water circulation inside the air conditioner.

[0019] 2. Protect the heat exchange system. Impurities entering the air conditioner pipeline will gradually adhere to the inner wall of the pipeline, reducing the inner diameter of the pipeline and hindering the normal flow of water or refrigerant. The filter device can intercept impurities to prevent the pipeline from being blocked and ensure smooth circulation of water and refrigerant. The heat exchanger is a key component of air conditioner heat exchange, and impurities will form a dirt layer on its surface. This not only affects the heat transfer efficiency, but also causes the local temperature of the heat exchanger to be too high, accelerating aging and damage. The filter device can prevent impurities from contacting the heat exchanger and maintain its efficient and stable operation.

[0020] 3. Extend the service life of the equipment. Impurities enter the air conditioner along with the airflow or water flow, which can cause friction with rotating parts such as fan blades and water pump impellers. Long-term effects can cause surface wear and tear, affecting the rotation accuracy and stability. The filter device can reduce the amount of impurities entering, reduce the wear and tear of the parts, and extend the service life. Some corrosive impurities (such as acidic dust and high-ionic-content limescale) entering the air conditioner can cause chemical reactions with metal parts, leading to corrosion. The filter device blocks these corrosive impurities, protects metal parts, and reduces the risk of corrosion.

[0021] 4. Improve energy efficiency. When the pipes and heat exchangers in the heat exchange system are kept clean, the heat exchange process can proceed normally. Refrigerant or circulating water can efficiently absorb or release heat, allowing the air conditioner to achieve the cooling or heating goal with lower energy consumption. If the heat exchange efficiency is reduced due to impurities blocking, the air conditioner needs to consume more energy to maintain the set temperature, resulting in increased energy consumption. The filter device ensures the cleanliness of the system, allowing the refrigerant to circulate smoothly, and the compressor does not need to overcome the additional resistance caused by impurities blocking, allowing it to operate under easier working conditions, reducing power consumption.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described in combination with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application. Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing the specific embodiments of the present application, and are not intended to limit the present application.

[0032] In the description of the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connecting", "fixing" should be understood in a broad sense, for example, it can be fixed connection, or detachable connection, or integrated; it can be mechanical connection, or electrical connection; it can be direct connection, or indirect connection through intermediate medium; it can be internal communication of two elements or interaction relationship between two elements. For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0033] Although the present application is disclosed with the preferred embodiments as above, it is not intended to limit the claims, and any person skilled in the art can make several possible changes and modifications without departing from the concept of the present application, therefore, the protection scope of the present application should be limited by the scope defined by the claims of the present application.

[0034] The working principle of the air conditioner is that: the inner machine exchanges heat through the heat exchanger to produce hot water, and then the hot water is delivered to the water distributor of the outdoor machine to flow to the wet curtain, and the heat is evaporated by the principle of air cooling + wet curtain evaporation, and the high-temperature water becomes normal-temperature water, and then flows through the heat exchanger of the inner machine, and the cycle is repeated.

[0035] According to the above principle, the working process of the air conditioner is as follows. Firstly, the temperature of the cooling circulating water is reduced to normal temperature by using the water curtain cooling method and the evaporative condensing method of the outdoor unit. Subsequently, the refrigerant and the cooling circulating water are heat exchanged through the heat exchange system inside the air conditioner, and the cold air is blown out of the air conditioner evaporator in the indoor unit. At the same time, the high-temperature cooling circulating water is transported to the upper part of the outdoor unit of the air conditioner by the circulating water pump, and under the action of the evaporative water curtain, the high-temperature water becomes normal temperature water, and then flows through the indoor unit again to reduce the temperature of the refrigeration device in the indoor unit, thereby forming a reciprocating circulation system.

[0036] The applicant finds that the existing air conditioner cannot solve the problem of smelling odor when using the air conditioner. During the water curtain cooling process, impurities are inevitably mixed in the water, whether it is a problem of the water source itself or caused by the use environment, which will cause the problems described in the background art. In order to pursue better use experience and improve the grade of the air conditioner, it is necessary to solve the above-mentioned problems.

[0037] The present application changes the structure of the outdoor unit of the air conditioner to eliminate odor, block impurities, protect the heat exchange system, prolong the service life of the equipment, improve energy efficiency, and improve the use experience of the air conditioner.

[0038] The present application is not limited to a specific indoor unit of the air conditioner, and the indoor unit of the air conditioner can be selected and adapted to the outdoor unit of the air conditioner according to actual needs.

[0039] As Figures 1-6This application discloses a water-cooled filtration air conditioner, including an outdoor unit assembly: a frame 1, with an internal space for housing; a water tank 2, located at the lower part of the frame 1, with a water inlet 21, an inlet 22, an outlet 23, and an overflow 24 on its side; the water inlet 21 is connected to an external water source, and water from the source enters the water tank 2 through the water inlet 21; the inlet 22 and outlet 23 are connected to the indoor unit; when the water level in the water tank 2 is higher than the overflow 24, water overflows from the overflow 24; a filter assembly 3, laid on the water tank 2, comprising a support member 33, a second filter member 32, and a first filter member 31 laid sequentially, the second filter member 32 being a fiber structure and the first filter member 31 being a mesh structure; and a spray assembly 4, comprising a water suction member 41 and a water spray member 42, the water suction member 41 spraying water from the water tank 2. Water tank 2 draws water, and the water sprayed by water sprayer 42 enters water tank 2 after being filtered by filter assembly 3. Ventilation section 5 is located on the side of frame 1. It mainly achieves better filtration effect by using filter assembly, that is, first physically intercepting and then adsorbing odors, so as to ensure that no odor is generated when the circulating water is delivered to the indoor unit. The core of this utility model technical solution is to lay support member 33, second filter member 32, and first filter member 31 in sequence. The filter assembly 3 is laid on water tank 2 in the above order. In addition, water sprayer 41 above filter assembly 3 and water suction member 42 extending into water tank 2 through filter assembly 3 are added to design the technical solution as a unified whole. It can intercept and adsorb, and can also play its role in sequence, so that the function of filter assembly can be maximized, thereby achieving the aforementioned technical effect.

[0040] Implementation Method 1

[0041] like Figures 1-6 As shown, a water-cooled filter air conditioner includes an outdoor unit component. Before the first use, water needs to be added through the water inlet 21 to the water level of the overflow outlet 24. Usually, tap water is drawn from the water pipe.

[0042] Specifically, water drawn in by the suction element 41 of the spray assembly 4 is sprayed out by the spray element 42 to form a water curtain. Since the ventilation section 5 introduces airflow, it accelerates the evaporation of water vapor and quickly removes heat. The water curtain formed by the spray element 42 pours onto the filter assembly 3, and after being filtered by the filter assembly 3, it enters the water tank 2. Because the suction element 41 continuously draws in water, and the spray element 42 continuously sprays out water to form a water curtain, water is replenished by the water inlet 21 after the water vapor evaporates. When the water level in the water tank 2 is higher than the overflow outlet 24, water overflows from the overflow outlet 24; this prevents water from overflowing to the top of the water tank 2 and then rising onto the filter assembly 3, causing odor transfer and affecting the filtration effect.

[0043] After being cooled, the water is supplied to the indoor unit for cooling through the outlet 23. The resulting hot water then returns to the outdoor unit's water tank 2 through the inlet 22.

[0044] According to the embodiment, the suspended particles in the water, such as silt, rust, algae, and large bacteria, are first physically intercepted by the mesh structure of the first filter, and then adsorbed by the adsorption performance of the fiber structure, including organic matter, pigment, odor, heavy metal ions, etc., to eliminate odor and improve the use experience of the water-cooled filter air conditioner.

[0045] The filter assembly 3 is composed of a support 33, a second filter 32, and a first filter 31 laid in sequence, wherein the support 33 provides support, Figures 3-6 It can be seen that the support 33 allows water to flow freely, and the double filtration by the second filter 32 and the first filter 31 ensures better filtration from a physical structure, eliminates odor, and avoids the odor feeling when blowing. First, the water is filtered by the first filter 31, and then filtered by the second filter 32, which not only achieves better filtration effect, but also is more targeted during cleaning and replacement, saving economic cost.

[0046] Embodiment 2

[0047] As Figures 3-7 shown, the difference between the embodiment and embodiment 1 is that the filter assembly of the embodiment is more specific, the support 33 is a stainless steel structure, the second filter 32 is filter cotton, and the first filter 31 is a dust screen. Specifically, the outer layer of the first filter includes a PET dust screen (with a mesh side length of 0.5-1.2 mm or a mesh number of 35-16), and the surface can also be coated with a silica coating. Specifically, the second filter uses gradient density fiber filter cotton, which is divided into three layers from top to bottom: polypropylene melt-blown cotton 321, glass fiber cotton 322, and hydrophobic modified non-woven fabric 323.

[0048] Specifically, the support can have various water permeation modes, such as round holes, long strip holes, zigzag lines, or curves. The stainless steel mesh not only provides good support, but also does not rust and pollute the water in the water tank 2.

[0049] The first filtration is implemented by the dust screen, and the mesh structure physically intercepts the suspended particles in the water, such as silt, rust, algae, and large bacteria. The dust screen can be easily cleaned to remove the suspended particle pollutants that cause odor. The surface coating of silica coating can increase the strength and resist the impact of the water curtain and the sand and stones therein.

[0050] Further adsorption is performed by the adsorption performance of the fiber structure, including organic matter, pigment, odor, heavy metal ions, etc., to further eliminate odor and improve the use experience of the air conditioner. Specifically, the second filter uses gradient density fiber filter cotton, which is divided into three layers from top to bottom: 30PPI polypropylene melt-blown cotton, 50PPI glass fiber cotton, and hydrophobic modified PET non-woven fabric.

[0051] The core function of the polypropylene meltblown cotton layer 321 (surface layer) is to form a dense mesh structure composed of ultra-fine fibers (diameter 1-5μm) through high-pressure meltblown process, with a mesh density of 30-50PPI (number of pores per inch), to intercept large particulate impurities (such as dust, willow catkins, insect remains, etc.), with a filtration efficiency of over 95% (for particles ≥10μm).

[0052] The core function of the glass fiber cotton layer 322 (intermediate layer) is that it is composed of borosilicate glass fibers (0.5-3μm in diameter) stacked in an interlaced manner to form a high porosity (≥85%) structure, which adsorbs fine suspended matter (such as PM2.5, oil mist, pollen, etc.) and achieves a filtration efficiency of over 85% for particles of 0.3-1μm.

[0053] The core function of the hydrophobic modified nonwoven layer 323 (bottom layer) is that the polyester (PET) nonwoven fabric is modified by fluorocarbon plasma, with a contact angle >120°, which blocks water vapor penetration and prevents the filter cotton from absorbing water and clumping.

[0054] Implementation Method 3

[0055] like Figures 1-6 As shown, the support component 33 is drawer-shaped, with a length of 500-1000mm, a width of 400-900mm, and a height of 10-50mm. Users can adjust it according to the usage scenario. For example, in factories or large spaces, a rack 1 with a larger length, width, and height ratio can be used, while in homes or small spaces, a rack 1 with a larger length, width, and height ratio can be used.

[0056] The rack 1 in this embodiment is not limited to the above scope. It can be implemented by increasing the length, width and height, or by using multiple racks.

[0057] Implementation Method 4

[0058] The difference from embodiments 1, 2, and 3 is that there are two support members 33, each 720mm long, 340mm wide, and 25mm high. These two support members 33 not only distribute the weight, allowing for a thinner support member 33, but also allow the water-absorbing member 41 to pass through them before drawing water from the water tank 2. In a further preferred embodiment, the water-absorbing member 41 is located in the middle of the frame 1. In a further preferred embodiment, the water-spraying member 42 is located at the upper part of the frame 1. In a further preferred embodiment, the first filter member 31 has square mesh with a side length of 0.5-1.2mm. In a further preferred embodiment, the first filter member 31 has a mesh size of 35-16. In a further preferred embodiment, the frame 1 can have four sides, with the ventilation section made of stainless steel mesh.

[0059] The above technical scheme has the following advantages: the structure is more reasonable, the stress is more balanced, and when cleaning and replacing, the nose and eyes are distinguished, so that the cleaning and replacement are more targeted, and the economic cost is further saved. The water absorption part is arranged in the middle part of the rack, providing a certain space for the filter assembly and the water tank, so that the machine can work for a long time when the water supply is stopped; the water spraying part is arranged in the upper part of the rack, so that the spraying distance is longer and the temperature drop is better; the first filter part has a square mesh, which is convenient for process manufacturing; the mesh of the first filter part is limited, so that the filtered material is accurately screened, and larger pollutants are prevented from entering the second filter part; the side of the rack is four sides, which is convenient for installing the ventilation part, so that better ventilation is achieved, and the ventilation part adopts a stainless steel mesh structure, which ensures good ventilation while avoiding the generation of rust odor.

[0060] The significant effects of adding a filter device to the water-cooled filter air conditioner outdoor unit mainly include: 1. High efficiency of blocking impurities. During the operation of the water-cooled filter air conditioner outdoor unit, it continuously inhales the surrounding air, and the circulating water also continuously flows. In this process, various suspended pollutants in the air, such as dust, sand, willow catkins, hair, etc., and possible scale, rust, etc. in the circulating water, all have the risk of entering the air conditioner. Once these impurities enter the internal machine, they will gradually accumulate inside. The added filter device, with its fine and scientifically designed filter screen structure, can effectively intercept these particulate pollutants. Whether it is suspended matter in the air or solid impurities in the water, it is difficult to break through the defense line of the filter device, effectively preventing it from entering the internal machine, and ensuring the cleanliness of the air circulation path and water circulation system inside the air conditioner, creating a relatively pure operating environment for the internal air conditioner. 2. Comprehensive protection of the heat exchange system. (1) Pipeline protection. The air conditioner pipeline is the channel for water or refrigerant circulation. When impurities enter the pipeline, they will gradually adhere to the inner wall of the pipeline. Over time, the amount of adhered impurities will gradually increase, causing the inner diameter of the pipeline to decrease. This not only hinders the normal flow of water or refrigerant, but also increases the resistance of the fluid flowing in the pipeline, affecting the efficiency of the entire circulation system. The filter device acts as a loyal guardian of the pipeline, intercepting impurities that may enter the pipeline. In this way, it prevents the pipeline from being clogged, ensuring that water and refrigerant can circulate smoothly in the pipeline, maintaining the stable operation of the system and reducing the hidden dangers caused by pipeline blockage. (2) Heat exchanger maintenance. The heat exchanger, as the core component of air conditioner heat exchange, its performance is directly related to the refrigeration or heating effect of the air conditioner. However, once impurities accumulate on the surface of the heat exchanger, a layer of dirt will be formed. This layer of dirt will become a barrier to heat transfer, significantly reducing the heat transfer efficiency, causing the air conditioner to consume more energy during heat exchange. At the same time, the presence of the dirt layer will also cause the local temperature of the heat exchanger to be too high. High temperature will accelerate the aging process of the heat exchanger, and even may cause component damage. The presence of the filter device can effectively prevent impurities from contacting the heat exchanger, keeping its working surface clean, and maintaining high efficiency and stable operation, ensuring that the heat exchange performance of the air conditioner remains at an excellent level for a long time. 3. Significantly prolong the service life of the equipment. (1) Reduce wear and tear. During the operation of the air conditioner, if impurities enter the internal machine with the airflow or water flow, they will rub against rotating components such as fan blades and water pump impellers. The continuous friction between these rotating components and impurities during long-term operation will cause wear and tear on the surface of the components. Once wear and tear occurs, it will not only affect the rotation accuracy of the components, but also may reduce their running stability, even cause vibration and noise problems. The addition of the filter device can effectively reduce the amount of impurities entering the internal machine of the air conditioner. The contact probability of rotating components and impurities is greatly reduced, thereby significantly reducing the degree of wear and tear, allowing these key components to maintain good working conditions, thereby prolonging the service life of the entire equipment. (2) Reduce corrosion.Some of the corrosive impurities, such as acidic dust, scale with excessive ion content, etc., once into the air conditioning system, will have a chemical reaction with metal parts. This chemical reaction will gradually erode the metal parts, resulting in corrosion. Corrosion not only weakens the structural strength of the metal parts, but also may cause leakage and other serious problems, affecting the normal operation and service life of the air conditioner. The filtering device can accurately block these corrosive impurities and isolate them from the air conditioning system. This provides a reliable protection barrier for the metal parts, effectively reduces the corrosion risk, and further ensures the long-term stable operation of the equipment.4. Effectively improve energy efficiency.(1) Maintain heat exchange efficiency. Keeping the pipes and heat exchangers in the heat exchange system clean is the basis for efficient operation of the air conditioner. When they are clean, the refrigerant or circulating water can efficiently absorb or release heat during the heat exchange process. This efficient heat exchange process enables the air conditioner to achieve the desired refrigeration or heating goal with lower energy consumption, achieving energy saving. On the contrary, if the heat exchange system is blocked by impurities, the inner diameter of the pipe is reduced, and the surface of the heat exchanger is covered with dirt, the heat exchange efficiency will be greatly reduced. In order to maintain the set temperature in the room, the air conditioner needs to consume more energy to operate, resulting in a significant increase in energy consumption. The filtering device keeps the heat exchange system clean and ensures efficient heat exchange process, effectively avoiding energy efficiency reduction caused by impurities.(2) Reduce the burden on the compressor. The compressor is an important energy-consuming component in the air conditioning system. When the system is blocked by impurities and the refrigerant circulation is not smooth, the compressor needs to overcome greater resistance to push the flow of refrigerant. This undoubtedly increases the working load of the compressor, which needs to consume more electricity to maintain operation. The filtering device can ensure the cleanliness of the system and make the refrigerant circulation path unobstructed. In this way, the compressor does not need to bear the additional resistance caused by impurity blockage and can run in relatively easy working conditions. This not only reduces the power consumption of the compressor, but also helps to prolong the service life of the compressor, improving the operation stability and energy efficiency of the entire air conditioning system.
