Description

Technical Field

[0001] The utility model belongs to the technical field of air-conditioning units, and particularly relates to an improved disinfection and deodorization air-conditioning unit. Background Art

[0002] The air conditioning unit is a combined air conditioning treatment system. Existing air conditioning units are generally composed of more than three functional sections, such as: primary new return air section, surface cooling water retaining section, heating section, humidification section, secondary return air section, fan section, silencer section, medium efficiency filtration section, sterilization section and heat recovery section, etc. Different air treatment requirements can be achieved through the combination of different functional sections.

[0003] For example, a Chinese utility model patent with publication number "CN208504575U" discloses a purification air-conditioning unit with a heat recovery device, including an air-conditioning case, the air-conditioning case is provided with an upper case and a lower case, the upper case is provided with a first fan, the lower case is provided with a second fan, a primary effect section, a surface cooling section, a heating section, a humidification section, a medium effect section and a disinfection air outlet section in sequence, the upper case is connected to the lower case through a heat recovery device, the first fan and the second fan are both installed on one side of the heat recovery device, and the first fan is arranged above the second fan, the primary effect section, the surface cooling section, the heating section, the humidification section, the medium effect section and the disinfection air outlet section are all installed on the other side of the heat recovery device, and an ultraviolet sterilization device is also installed between the humidification section and the medium effect section.

[0004] For another example, the Chinese utility model patent with publication number "CN217330042U" discloses a fresh air air-conditioning unit with a sterilization function, comprising a shell, one end of which is provided with a fresh air filter section and an exhaust section and the other end is provided with an indoor return air filter section and an indoor supply air section; a full heat exchange section, a sterilization component, a cooling and heating component, an air supply fan and a silencer component are arranged in sequence in the shell; an electric ventilation valve is arranged between the indoor return air filter section and the sterilization component; the indoor air supply section comprises an air supply filter, an air supply flange and an indoor air supply port arranged in sequence; the indoor return air filter section comprises a return air filter, a return air flange and an indoor return air port arranged in sequence; the exhaust section comprises an exhaust fan, an exhaust flange and an outdoor exhaust port arranged in sequence; the fresh air filter section comprises a fresh air port, a fresh air flange and a fresh air filter that cooperate with each other.

[0005] As mentioned above, most of the existing air-conditioning units achieve the effects of sterilization, disinfection and deodorization by installing ultraviolet disinfection devices and deodorization devices with activated carbon, photocatalyst or ozone. Since the disinfection and deodorization capabilities of activated carbon are relatively weak, the disinfection and deodorization effects of the air-conditioning units are easily poor. The cost of deodorization devices with photocatalysts or ozone is relatively high, and the above-mentioned deodorization devices usually need to be used in conjunction with ultraviolet disinfection devices. The overall manufacturing cost is relatively high, and the structure of the air-conditioning unit needs to be improved.

[0006] In view of this, the applicant conducted in-depth research on the above issues, which led to the present case. Utility Model Content

[0007] The utility model aims to provide an improved disinfection and deodorization air conditioning unit with good disinfection and deodorization effect and low manufacturing cost.

[0008] In order to achieve the above object, the utility model adopts the following technical solution:

[0009] An improved disinfection and deodorization air conditioning unit, comprising an air conditioning case having an upper case and a lower case, wherein one end of the lower case is provided with a fresh air inlet, and the other end is provided with an air outlet, the upper case is provided with an exhaust outlet at one end corresponding to the fresh air inlet, and the other end is provided with a return air inlet, and a fresh air section, a primary and secondary efficiency filter section, a first humidification section, a surface cooling section, a heating section, a second humidification section, a fan section, a flow equalization section, a sterilizing filter section, and an air supply section are sequentially arranged between the fresh air inlet and the air outlet;

[0010] A coil unit is provided in the surface cooling section, and a first tilted-fin cooling coil and a second tilted-fin cooling coil are provided in the coil unit. The first tilted-fin cooling coil and the second tilted-fin cooling coil are arranged in sequence along the direction from the fresh air inlet to the air supply outlet.

An inner wall is provided in the lower box body, and the tilted fins and the inner wall in the first tilted-fin cooling coil and the second tilted-fin cooling coil are made of sterilization aluminum material.

[0011] Furthermore, a water baffle is provided in the surface cooling section. The water baffle is arranged at a position close to the heating section and is made of sterilizing aluminum material.

[0012] Furthermore, the sterilizing filter segment has a sterilizing mesh body, which includes a plurality of aluminum alloy wires, and gaps are formed between adjacent aluminum alloy wires for blocking impurities and allowing air flow to pass through. The surface of the aluminum alloy wire is compounded with an anodized film, and the surface of the anodized film is compounded with a sterilizing layer.

[0013] Furthermore, a heat conversion section is provided between the primary and secondary efficiency filtration sections and the first humidification section. The heat conversion section is arranged vertically and extends from the lower box body to the upper box body. The heat conversion section is a rotary heat recovery device or a plate cross heat recovery device.

[0014] Furthermore, an exhaust section, the heat conversion section, the middle section, the primary filter section and the return air section are sequentially provided between the exhaust port and the return air port. The exhaust section is arranged above the fresh air section and the primary and secondary filter sections, and the exhaust section, the fresh air section and the primary and secondary filter sections are all arranged on the same side of the heat conversion section.

[0015] By adopting the above-mentioned design scheme, the beneficial effects of the utility model are:

[0016] 1. In the air-conditioning unit of the utility model, air enters from the fresh air inlet, and after being humidified by the first humidifying section, the air, the first tilted-blade cooling coil, the second tilted-blade cooling coil and the sterilization net become moist and produce a certain degree of adhesion under the action of the first humidifying section. The sterilization net forms a sterilization net with a high-efficiency moist water film under the action of the water vapor of the air conditioner. When the air flows, the bacteria and viruses in the air are intercepted by the moist first tilted-blade cooling coil, the moist second tilted-blade cooling coil and the moist sterilization net. Since the flaps are made of sterilization aluminum material, a better sterilization effect is achieved on the bacteria and viruses in the air, and the odor in the air is removed at the same time. Combined with the surface sterilization of the inner wall made of sterilization aluminum material in the lower box body, a three-dimensional disinfection effect is produced, the content of bacteria and viruses in the air is greatly reduced, and the disinfection and deodorization effect is good. The utility model uses the disinfection effect produced by the manufacturing materials of the equipment itself without producing harmful substances, and there is no need to additionally set up a deodorizing device and an ultraviolet disinfection device, so the manufacturing cost and daily maintenance cost are greatly reduced.

[0017] 2. The air-conditioning unit of the utility model has a three-dimensional disinfection effect. The three-dimensional disinfection causes the cell walls of bacteria and viruses to rupture, thereby causing the death of bacteria and viruses, making it impossible for bacteria and viruses to survive on the inner wall of the lower box, thereby solving the problem that bacteria and viruses in traditional air-conditioning units are easy to survive on the inner wall of the air-conditioning unit and are difficult to disinfect.

[0018] Furthermore, the air is disinfected by the sterilization net and the flaps made of sterilization aluminum in the flap-type cooling coil, and then passes through the water baffle made of sterilization aluminum material in the surface cooling section and the sterilization net body in the sterilization filter section for multiple disinfections, achieving efficient and comprehensive disinfection and deodorization effects.

[0019] Furthermore, a heat conversion section is provided between the upper box body and the lower box body to convert the heat of the indoor and outdoor air, thereby reducing the load of the air conditioning system and achieving energy-saving effect.

[0020] Furthermore, the lift tab is made of bactericidal aluminum material to form a disinfection module, which solves the problem that traditional lift tabs have no bactericidal effect and naturally breed bacteria and viruses due to moisture during the use of the air conditioner.

The surface cooling section 14 is provided with a conventional coil machine in this field, and the coil machine is provided with a plurality of groups of warp-type cooling coils. The coil machine cools the air by passing the refrigerant into the plurality of groups of warp-type cooling coils.

Different from the prior art, the coil machine in the utility model is provided with two groups of warp-type cooling coils, that is, the coil machine is provided with a first warp-type cooling coil 141 and a second warp-type cooling coil 142. The first warp-type cooling coil 141 and the second warp-type cooling coil 142 are arranged in sequence from the fresh air inlet 1 to the air outlet 2. The flaps 143 in the first flap-type cooling coil 141 and the second flap-type cooling coil 142 of the new type are both made of sterilizing aluminum material; a sterilizing net 144 is provided between the first flap-type cooling coil 141 and the second flap-type cooling coil 142, and the sterilizing net 144 can be a conventional sterilizing net in the art, such as the sterilizing net introduced in the authorization announcement number "CN212644886U" and the name "A Sterilizing Net and Sterilizing Air Purifier"; when in use, multiple sterilizing nets 144 can be provided between the first flap-type cooling coil 141 and the second flap-type cooling coil 142 according to actual conditions to achieve a better sterilization effect;

[0045] Furthermore, a water baffle 145 is also provided in the surface cooling section 14, and the water baffle 145 is arranged near the heating section 15.

[0047] The lower box 101 has an inner wall 103. It should be noted that in the present invention, the inner wall 103 is made of the above-mentioned sterilization aluminum material. When the air flows in the lower box 101, the bacteria and viruses in the air will touch the inner wall 103 of the lower box 101, and will be disinfected by the sterilization aluminum material of the inner wall 103, thereby achieving a three-dimensional disinfection effect.

[0048] Furthermore, a heat conversion section 21 is provided between the primary and secondary efficiency filter sections 12 and the first humidification section 13. The heat conversion section 21 is arranged vertically and extends from the lower box body 101 to the upper box body 102. A heat recovery device is provided in the heat conversion section 21. In actual applications, when the fresh air from the fresh air outlet 1 or the air recovered from the return air outlet 4 passes through the heat recovery device, the heat recovery device can perform heat conversion on the air, thereby reducing the load of the air-conditioning unit and achieving energy-saving effect. It should be noted that the heat recovery device provided in the heat conversion section 21 in this embodiment adopts a conventional rotary heat recovery device or a plate-type cross-type heat recovery device in the field. As long as the above-mentioned effect can be achieved, the specific structure will not be described in detail here. The exhaust section 31 is provided above the fresh air section 11 and the primary and secondary efficiency filter section 12, and the exhaust section 31, the fresh air section 11 and the primary and secondary efficiency filter section 12 are all provided on the same side of the heat conversion section 21.

[0049] A conventional heating device is provided in the heating section 15, and the surface cooling section 14, the heating section 15 and the second humidifying section 16 can be opened and closed according to the changes in indoor temperature or humidity and actual needs to ensure indoor comfort; the fan section 17 is used to transport the air in the fresh air section 11 to the direction of the air outlet 2, and the fan section 17 is provided with a conventional fan in this field, such as a centrifugal fan; the flow equalizing section 18 is provided with a conventional flow equalizer in this field, and the function of the flow equalizing section 18 is mainly to slow down and diffuse the concentrated, high-speed airflow coming out of the fan section 17 and evenly distribute it to the sterilizing filter section 19, so that the air can pass through the sterilizing filter section 19 at a uniform speed, which helps to improve the sterilization effect of the sterilizing filter section 19;

[0050] The sterilizing filter segment 19 has a sterilizing mesh body 191, and the sterilizing mesh body 191 includes a plurality of aluminum alloy wires 192, and gaps are formed between adjacent aluminum alloy wires 192 for blocking impurities and allowing airflow to pass through. Figure 2As shown, the surface of the aluminum alloy wire 192 is compounded with an anodized film 193, and the surface of the anodized film 193 is compounded with a bactericidal layer 194; in the utility model, the aluminum alloy wires 192 can be arranged in parallel. Preferably, the aluminum alloy wires 192 are crisscrossed, specifically interwoven with a plain weave to form an interwoven structure of warp yarns and weft yarns in a woven fabric; the above-mentioned bactericidal layer 194 is a copper layer or a silver layer; the bactericidal layer 194 is attached to the anodized film 193 so that the aluminum alloy wire 192 has an antibacterial and bactericidal effect. In the utility model, the anodized film 193 is formed by a conventional aluminum alloy anodizing process, and the bactericidal layer 194 is formed by a conventional electrodeposition process, such as in the authorized public The Chinese invention patent with notification number CN104152969B and name “A method for coloring aluminum alloy with alternating current electrolytic deposition of silver and copper” discloses the corresponding anodizing and electrodeposition processes. The utility model only needs to adjust the corresponding parameters. Compared with the existing filter cloth layer and multi-adsorption layer air-conditioning filter structure, the sterilization mesh 191 selected by the utility model forms an anodized film 193 and a sterilization layer 194 on the surface of the aluminum alloy wire 192, so that the air entering and exiting the sterilization mesh 191 can contact the sterilization layer 194. The sterilization filter segment 19 serves as the final disinfection module "protection segment" to achieve efficient disinfection and deodorization effects. The air supply segment 20 is a cavity for accommodating air.

[0051] In the upper box body 102, the return air section 34 is a cavity for accommodating air, and a conventional primary filter is provided in the primary filter section 33 for preliminary filtration of the recovered air. The middle section 32 is also a conventional maintenance section. The middle section 32 is mainly for the convenience of overhaul or maintenance of the various components in the air-conditioning case 100. The exhaust section 31 is used to transport the air recovered in the return air section 34 toward the exhaust port 3. Correspondingly, a conventional fan in the field is also provided in the exhaust section 31.

[0052] Disinfection and working principle of the air conditioning unit of the utility model:

[0053] Utilizing the disinfection principle of dynamic air circulation and static contact of sterilized materials of the air conditioning unit, the external air enters from the fresh air inlet 1 of the lower box 101 and flows toward the air supply outlet 2, passes through the primary and secondary filter sections 12 for preliminary filtration, and then passes through the heat conversion section 21 for heat conversion before continuing to flow toward the air supply outlet 2. At this time, there are still certain bacteria and viruses in the air. Afterwards, when the air passes through the first humidification section 13 and the surface cooling section 14, the first humidification section 13 is started for humidification, and the air, the first flap cooling coil 141, and the second flap cooling coil The tube 142 and the sterilizing net 144 become moist and have a certain degree of adhesion under the action of the first humidifying section 13. When the moist air passes through the moist first flap cooling coil 141, the moist second flap cooling coil 142 and the moist sterilizing net 144, the bacteria and viruses in the air can stay on the sterilizing net 144 and the flap 143 made of sterilizing aluminum for a sufficient time, thereby achieving a further sterilization effect on the bacteria and viruses in the air, and removing the odor in the air at the same time. When cooling is needed in summer, the surface cooling section 14 is started. The coil unit in the cooling coil unit passes the refrigerant into the first fin cooling coil unit 141 and the second fin cooling coil unit 142 to cool the air. When the air cooled by the coil unit passes through the water baffle 145, the bacteria and viruses remaining in the air are further disinfected by the sterilizing aluminum of the water baffle 145. The water baffle 145 made of the sterilizing aluminum material is not easy to adhere to bacteria, thus avoiding the problem of easy breeding and residual bacteria on the traditional water baffle. After that, the air passes through the heating section 15, the second humidification section 16, the fan section 17 and the flow equalization section 18 and reaches the sterilizing filter section 19. Correspondingly, when heating is needed in winter, the heating section 15 is turned on to heat the air; after the air reaches the sterilizing filter section 19, the remaining bacteria and viruses in the air are sterilized again by the sterilizing mesh 191, and then the clean air is sent out from the air supply port 2 through the air supply section 20; since the inner wall 103 of the lower box 101 is made of sterilizing aluminum material, when the air flows in the lower box 101, the bacteria and viruses in the air will touch the inner wall 103 of the lower box 101, and thus be disinfected by the sterilizing aluminum on the inner wall 103, producing a three-dimensional disinfection effect;

[0054] The recovered air enters the upper box 102 from the return air port 4 and moves toward the exhaust port 3, passing through the return air section 34, the primary filter section 33 and the middle section 32 in sequence to reach the heat conversion section 21. The recovered air converts heat in the heat conversion section 21 in the upper box 102 and is discharged through the exhaust port 3 through the exhaust section 31.

[0055] Compared with the prior art, the air conditioning unit of the utility model enters from the fresh air inlet 1, and after being humidified by the first humidification section 13, the air, the first flap type cooling coil 141, the second flap type cooling coil 142 and the sterilization net 144 become moistened and have a certain degree of adhesion under the action of the first humidification section. The sterilization net 144 forms a sterilization net 144 with a high-efficiency moist water film under the action of the water vapor of the air conditioner. When the air flows, the bacteria and viruses in the air pass through the moistened first flap type cooling coil The coil 141, the wet second flap cooling coil 142 and the wet sterilization net 144 intercept, so that the bacteria and viruses in the air are effectively disinfected by the sterilization net 144 in the surface cooling section 14 and the flaps 143 and the water baffle 145 made of sterilization aluminum material. The utility model changes the coil machine into a combination of two sets of flap cooling coils based on the evaporation area of ​​the flaps of the traditional coil machine, and the flaps 143 of the utility model are made of sterilization aluminum material to form a disinfection module, which solves the problem of traditional The flaps have no bactericidal effect and are prone to breed bacteria and viruses; combined with the sterilization net 144 set in the middle of the first flap type cooling coil 141 and the second flap type cooling coil 142 of the utility model, a better sterilization effect is achieved, and the air is subsequently sterilized by the sterilization net 191 in the sterilization filter segment 19, and then cooperated with the surface sterilization of the inner wall 103 made of sterilization aluminum material in the lower box 101, a three-dimensional disinfection effect is produced, and the cell walls of bacteria and viruses are ruptured through three-dimensional disinfection, which leads to the death of bacteria and viruses, so that bacteria and viruses cannot survive on the inner wall 103 of the lower box 101, which solves the problem that bacteria and viruses in traditional air-conditioning units are easy to survive on the inner wall of the air-conditioning unit and are not easy to sterilize; the content of bacteria and viruses in the air is greatly reduced, and the disinfection and deodorization effect is good. The utility model uses the disinfection effect produced by the equipment's own manufacturing materials without producing harmful substances, and there is no need to additionally set up a deodorizing device and an ultraviolet disinfection device, so the manufacturing cost and daily maintenance cost are greatly reduced.

[0056] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
