Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and in particular to a composite air conditioning system. Background Technology

[0002] As people's requirements for indoor environmental comfort continue to increase, air conditioning systems are being used more and more widely in the building sector.

[0003] In existing air conditioning technologies, there are two common approaches to achieving cooling functionality. One approach uses a simple compression refrigeration system, where the refrigerant is compressed, condensed, throttled, and evaporated by a compressor to achieve heat transfer and cooling. The other approach utilizes evaporative cooling technology, which absorbs heat through water evaporation to lower the air temperature. This approach offers advantages such as energy saving and environmental friendliness. However, simple compression refrigeration systems consume a lot of energy and have high operating costs, which does not meet current energy conservation and emission reduction requirements. While evaporative cooling is energy-saving and environmentally friendly, its cooling effect is limited in high humidity environments and cannot provide stable cooling under all climatic conditions. Therefore, this application provides a composite air conditioning system that can adapt to environmental conditions and selectively switch between different cooling effects. Summary of the Invention

[0004] To address the aforementioned problems, this application provides a composite air conditioning system.

[0005] The composite air conditioning system provided in this application adopts the following technical solution: A composite air conditioning system includes an evaporative cooling module, a compression refrigeration module, a shared exhaust fan, a shared supply fan, a valve assembly, an air inlet duct, a supply air duct, and an exhaust air duct. The evaporative cooling module and the compression refrigeration module are stacked vertically. One end of the supply air duct is connected to the cooling end of the evaporative cooling module, and the other end is connected to the cooling end of the compression refrigeration module. The shared supply fan is connected to the supply air duct. The cooling ends of both the evaporative cooling module and the compression refrigeration module are connected to their respective corresponding air inlet ducts. The shared exhaust fan is connected to the exhaust air duct, and the exhaust air duct is also connected to the heat dissipation ends of both the evaporative cooling module and the compression refrigeration module. The valve assembly, consisting of several valves, is located in the supply air duct and the exhaust air duct and is used to regulate the supply and exhaust air paths.

[0006] By adopting the above technical solution, the composite air conditioning system stacks the evaporative cooling module and the compression refrigeration module vertically, combining the energy-saving and environmentally friendly advantages of the evaporative cooling module with the stable cooling effect of the compression refrigeration module. Furthermore, by adjusting the air supply path through the air valve group, different cooling modes can be selected and switched according to the environment as needed. This avoids the problems of high energy consumption and high operating costs of using a compression refrigeration system alone, as well as the limited cooling effect of evaporative cooling technology in high humidity environments, thus achieving different cooling effects for different environments.

[0007] Optionally, the evaporative cooling module is equipped with two sets of air inlet channels.

[0008] By adopting the above technical solution, setting up two sets of air inlet channels can achieve accurate air distribution, ensuring the heat dissipation efficiency and cooling efficiency within the evaporative cooling module.

[0009] Optionally, the air inlet channel of the evaporative cooling module is equipped with a deflector grille.

[0010] By adopting the above technical solution, the airflow grille is used to guide airflow into the evaporative cooling module to improve the uniformity of heat exchange.

[0011] Optionally, the air valve assembly includes a first air valve and a second air valve, with the first air valve located near the air supply channel of the evaporative cooling module and the second air valve located near the air supply channel of the compression refrigeration module.

[0012] By adopting the above technical solution, the first air valve and the second air valve can easily adjust the air supply path of the evaporative cooling module and the compression refrigeration module, and then switch different cooling effects according to the needs to meet the usage requirements in different environments.

[0013] Optionally, the air inlet of the shared exhaust fan is connected to the air outlet of the heat dissipation end of the compressor refrigeration module through an exhaust duct.

[0014] By adopting the above technical solution, the shared exhaust fan can dissipate the heat generated at the heat dissipation end of the compressor refrigeration module, ensuring the normal heat dissipation of the compressor refrigeration module, thereby ensuring the stable operation of the compressor refrigeration module and contributing to the stable operation of the entire composite air conditioning system.

[0015] Optionally, the damper assembly may also include a third damper and a fourth damper; the third damper is located in the exhaust channel between the common exhaust fan and the heat dissipation end of the evaporative cooling module, and the fourth damper is located in the exhaust channel between the common exhaust fan and the heat dissipation end of the compression refrigeration module.

[0016] By adopting the above technical solutions, the third and fourth air valves can regulate the exhaust channel from the heat dissipation end of their respective modules to the common exhaust fan, adjust the opening and closing of the exhaust path, meet the cooling needs under different environments, and make the system operate more flexibly and efficiently.

[0017] Optionally, the third air valve opens and closes synchronously with the first air valve; the second air valve opens and closes synchronously with the fourth air valve.

[0018] By adopting the above technical solution, the third air valve and the first air valve are opened and closed synchronously, and the second air valve and the fourth air valve are opened and closed synchronously. This enables the evaporative cooling module and the compression refrigeration module of the composite air conditioning system to work independently without interfering with each other, achieving stable switching between different cooling modes, and allowing for selection of different cooling effects according to environmental requirements.

[0019] Optionally, when the first, second, third, and fourth air valves of the air valve group are opened simultaneously, the evaporative cooling module and the compression refrigeration module operate synchronously.

[0020] By adopting the above technical solutions, the composite air conditioning system adapts to the environment according to the needs, and at the same time utilizes the energy-saving and environmentally friendly characteristics of the evaporative cooling module and the stable cooling characteristics of the compression refrigeration module to provide a stable and efficient cooling effect under different climatic conditions.

[0021] Optionally, a dehumidification channel is provided between the two sets of air inlet channels of the evaporative cooling module. The dehumidification channel connects the two sets of air inlet channels, and the end of the dehumidification channel is connected to the air supply channel and is located between the second air valve and the cooling end of the compression refrigeration module; a fifth air valve is provided in the dehumidification channel.

[0022] By adopting the above technical solution, the cooling end of the compression refrigeration module is opened, and the slight cold air generated by the compression refrigeration module is transported from the dehumidification channel to the air inlet channel of the evaporative cooling module. The cold air mixes with the moisture in the air inlet channel. The moisture is affected by the cold air and will condense into water droplets and adhere to the surface of the air inlet channel, thereby reducing the impact of moisture on the evaporative cooling module.

[0023] Optionally, the air inlet channel of the evaporative cooling module is equipped with two dehumidification plates. The two dehumidification plates are inclined in different directions and are spaced apart end to end. The connection port of the dehumidification channel is located between the two dehumidification plates.

[0024] By adopting the above technical solution, when humid air enters the air inlet channel, it first comes into contact with the dehumidification plate. After the dehumidification plate, which is cooled by the cold air transported by the dehumidification channel, comes into contact with the dehumidification plate, the moisture condenses into water droplets and adheres to the dehumidification plate, thereby achieving the effect of dehumidifying the humid air.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The composite air conditioning system stacks the evaporative cooling module and the compression refrigeration module vertically, combining the energy-saving and environmentally friendly advantages of the evaporative cooling module with the stable cooling effect of the compression refrigeration module. Furthermore, by regulating the air supply path through the air valve group, different cooling modes can be selected and switched according to the needs of the environment. This avoids the problems of high energy consumption and high operating costs of using the compression refrigeration system alone, as well as the limited cooling effect of evaporative cooling technology in high humidity environments, and achieves different cooling effects for different environments. 2. Setting up two sets of air intake channels can achieve accurate air distribution, ensuring the heat dissipation efficiency and cooling efficiency within the evaporative cooling module; 3. The first and second air valves can easily adjust the air supply paths of the evaporative cooling module and the compression refrigeration module, thereby switching between different cooling effects as needed to meet the usage requirements in different environments.

[0031] Throughout this specification, when it is said that a device is "connected" to another device, this includes not only "direct connection" but also "indirect connection" by placing other components in between. Furthermore, when it is said that a device "comprises" a certain constituent element, unless otherwise stated otherwise, this does not exclude other constituent elements, but rather implies that other constituent elements may be included.

[0032] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail below.

[0033] This application discloses a composite air conditioning system.

[0034] A composite air conditioning system, reference Figure 1 and Figure 2 As shown, it includes an evaporative cooling module 1, a compression refrigeration module 2, a common exhaust fan 3, a common supply fan 4, a valve group 5, an air inlet channel 6, an air supply channel 7, and an exhaust channel 8; the evaporative cooling module 1 and the compression refrigeration module 2 are stacked vertically, and a controller can be installed on the top of the evaporative cooling module 1 to control the temperature and the direction of airflow.

[0035] Evaporative cooling module 1 provides evaporative cooling by absorbing heat through water evaporation, thus lowering the air temperature. It has low energy consumption and is energy-saving and environmentally friendly. Compression refrigeration module 2, on the other hand, achieves heat transfer and cooling by compressing, condensing, throttling, and evaporating the refrigerant. This method has a good cooling effect but consumes more energy. Evaporative cooling module 1 can be stacked vertically on top of compression refrigeration module 2. Either evaporative cooling module 1 or compression refrigeration module 2 can be used selectively based on the environment or needs. For example, when the weather is not hot enough and the humidity is normal, evaporative cooling module 1 can be selected to reduce energy consumption. In hot or humid environments, compression refrigeration module 2 can be selected to obtain a stable cooling effect, thus achieving the function of adapting to different environments.

[0036] Evaporative cooling module 1 adopts a tubular indirect evaporative cooling structure, with an internal heat exchanger and water pump. The heat exchanger is a multi-row in-line corrugated finned tube, which can increase the heat exchange area and improve the heat exchange efficiency.

[0037] The outer surface of the tube bundle can be covered with a hydrophilic coating, which allows water to spread better on the tube bundle surface, enhancing the evaporative cooling effect. Circulating cooling water flows inside the tube, and there is a secondary air flow channel outside the tube. The circulating cooling water flows inside the tube and absorbs the heat of the air in the secondary air flow channel outside the tube. The heat is then exchanged through a heat exchanger to achieve the evaporative cooling effect.

[0038] The tubular indirect evaporative cooling structure is an existing structure and will not be specified in detail here.

[0039] The compression refrigeration module 2 can be a scroll compression refrigeration device, which may include a compressor, a condenser, a throttling element and an evaporator. The condenser is a microchannel flat tube condenser, with its air-facing surface parallel to that of the evaporator, and a flow guide baffle is provided between them. The flow guide baffle has a uniformly distributed array of rectangular through holes. The microchannel flat tube condenser has high heat exchange efficiency and a compact structure. The flow guide baffle can make the airflow pre-cooled by the evaporator enter the heat dissipation surface of the condenser more evenly, thereby improving the condensation effect.

[0040] Alternatively, other types of condensers, such as shell-and-tube condensers, can be used as replacements.

[0041] The evaporator is a copper tube aluminum fin heat exchanger with open-window louvered fins. The open-window louvered fins can enhance air turbulence and improve heat exchange efficiency. Other types of heat exchangers, such as plate heat exchangers, can also be selected according to requirements.

[0042] One end of the air supply duct 7 is connected to the cooling end of the evaporative cooling module 1, i.e., the cooling end of the heat exchanger, and the other end is connected to the cooling end of the compression refrigeration module 2, i.e., the evaporator. The shared air supply fan 4 is connected to the air supply duct 7. Through the shared air supply fan 4, the cold air from the cooling end of the heat exchanger or the evaporator can be delivered to the application environment through the air supply duct 7. The evaporative cooling module 1 and the compression refrigeration module 2 share a single shared air supply fan 4, eliminating the need to add multiple sets of air supply fans, reducing the number of devices and energy consumption, and improving energy efficiency.

[0043] Both the cooling end of the evaporative cooling module 1 and the cooling end of the compression cooling module 2 are connected to an air inlet channel 6. The air inlet channel 6 is used to deliver air into the evaporative cooling module 1 or the compression cooling module 2. The air inlet channels 6 of the two modules are not shared and can be set independently to provide fresh air. After entering through the air inlet channel 6, the fresh air is delivered to the cooling end of the evaporative cooling module 1 or the compression cooling module 2. After mixing with the cold air, it is delivered to the application environment by the shared blower 4 through the air supply channel 7.

[0044] The vortex compressor refrigeration equipment is an existing structure and will not be specified in detail here.

[0045] The shared exhaust fan 3 is connected to the exhaust duct 8. The shared exhaust fan 3 can be embedded in the exhaust duct 8, and both ends of the exhaust duct 8 are connected to the heat dissipation end of the evaporative cooling module 1 and the heat dissipation end 7 of the compression refrigeration module, respectively. The shared exhaust fan 3 also provides exhaust air to the heat dissipation ends of the evaporative cooling module 1 and the compression refrigeration module 2. The heat dissipation end of the evaporative cooling module 1 is the heat dissipation point of the heat exchanger, and the heat dissipation end of the compression refrigeration module 2 is the condenser. The shared exhaust fan 3 generates negative pressure, which carries the heat generated at the heat dissipation ends of the evaporative cooling module 1 and the compression refrigeration module 2 out with the air through the exhaust duct 8, achieving a stable heat dissipation effect. The shared exhaust fan 3 can achieve synchronous exhaust, eliminating the need to add multiple sets of blowers, reducing the number of equipment and energy consumption, and improving energy efficiency.

[0046] Both the evaporative cooling module 1 and the compression refrigeration module 2 are equipped with fresh air inlets 9 for the air intake of the exhaust channel 8, so that when the shared exhaust fan 3 exhausts air, fresh air enters from the fresh air inlets 9 and comes into contact with the heat dissipation ends of the evaporative cooling module 1 and the compression refrigeration module 2 for heat exchange.

[0047] Among them, the air inlet channel 6, air supply channel 7 and air exhaust channel 8 mentioned above are all made of metal rectangular air ducts.

[0048] refer to Figure 1 As shown, the air valve assembly 5 consists of several air valves and is located in the air supply channel 7 and the air exhaust channel 8. It is used to regulate the air supply and exhaust paths. The air valve assembly 5 closes or opens the air supply channel 7 and the air exhaust channel 8 to adjust the airflow. The opening and closing of the air valve assembly 5 is related to the opening and closing of the evaporative cooling module 1 and the compression refrigeration module 2. For example, when the evaporative cooling module 1 is started, the air valve assembly 5 opens the corresponding air supply channel 7 and the air exhaust channel 8 of the evaporative cooling module 1, so that the evaporative cooling module 1 can generate cooling and stably deliver it to the application environment. When the compression refrigeration module 2 is closed, the corresponding air supply channel 7 and the air exhaust channel 8 are also closed.

[0049] Specifically, the composite air conditioning system stacks the evaporative cooling module 1 and the compression refrigeration module 2 vertically, combining the energy-saving and environmentally friendly advantages of the evaporative cooling module 1 with the stable cooling effect of the compression refrigeration module 2. Furthermore, by regulating the air supply path through the air valve group 5, different cooling modes can be selected and switched according to the environment as needed. This avoids the problems of high energy consumption and high operating costs of using a compression refrigeration system alone, as well as the limited cooling effect of evaporative cooling technology in high humidity environments, thus achieving different cooling effects for different environments.

[0050] Further reference Figure 1 or Figure 2As shown, the evaporative cooling module 1 is equipped with two sets of air inlet channels 6. The two sets of air inlet channels 6 are to ensure the heat dissipation efficiency and cooling efficiency within the evaporative cooling module 1. The evaporative cooling module 1 is a tubular indirect evaporative cooler, which uses water vapor to absorb heat and cool the secondary air outside the tube, and then transfers the coolness to the primary air inside the tube through heat conduction through the tube wall, thereby achieving equal humidity cooling of the primary air. Therefore, the primary air flow channel and the secondary air flow channel are respectively connected to the two sets of air inlet channels 6. Setting two sets of air inlet channels 6 can achieve accurate air distribution.

[0051] The air inlet channel 6 of the compression refrigeration module 2 can also be selected as the air intake grille 61.

[0052] Furthermore, refer to Figure 2 As shown, the air inlet channel 6 of the evaporative cooling module 1 is provided with a flow guide grille 61. The flow guide grille is composed of inclined metal sheets arranged in parallel at equal intervals. The inclination angle of the metal sheets is 30 degrees. The flow guide grille can guide the air to enter the secondary air flow channel evenly, thereby improving the uniformity of heat exchange. The metal sheets can also be made of other materials such as plastic, as long as they can play a guiding role.

[0053] In some embodiments, reference Figure 1 As shown, the air valve group 5 includes a first air valve 51 and a second air valve 52. The first air valve 51 is located near the air supply channel 7 of the evaporative cooling module 1, and the second air valve 52 is located near the air supply channel 7 of the compression refrigeration module 2. This allows for convenient adjustment of the air supply paths of the evaporative cooling module 1 and the compression refrigeration module 2, thereby switching between different cooling effects as needed to meet the usage requirements in different environments.

[0054] In some embodiments, reference Figure 1 As shown, the air inlet of the shared exhaust fan 3 is connected to the air outlet of the heat dissipation end of the compressor refrigeration module 2 through the exhaust channel 8. This limitation is used to limit the airflow direction of the shared exhaust fan 3, that is, the air inlet of the shared exhaust fan 3 is connected to the air outlet of the condenser, and the other side of the condenser is the air inlet side. The air inlet side is independently supplied with air. When the shared exhaust fan 3 is running, a negative pressure is formed in the exhaust channel 8, thereby using the exhaust channel 8 to extract and discharge the heat from the condenser. The air inlet side of the condenser is simultaneously supplied with fresh air to ensure the normal heat dissipation of the compressor refrigeration module 2, thereby ensuring the stable operation of the compressor refrigeration module 2, which is conducive to the stable operation of the entire composite air conditioning system.

[0055] The exhaust duct 8 consists of two sets of exhaust pipes. A common exhaust fan 3 is set at the intersection of one end of the two sets of exhaust pipes, and the other end is connected to the cooling end of the evaporative cooling module 1 and the compression refrigeration module 2, thereby realizing that the evaporative cooling module 1 and the compression refrigeration module 2 share a common exhaust fan.

[0056] Further reference Figure 1As shown, the air valve group 5 also includes a third air valve 53 and a fourth air valve 54; the third air valve 53 is disposed in the exhaust channel 8 between the common exhaust fan 3 and the heat dissipation end of the evaporative cooling module 1, and the fourth air valve 54 is disposed in the exhaust channel 8 between the common exhaust fan 3 and the heat dissipation end of the compression refrigeration module 2.

[0057] The air valve group 5 is equipped with a third air valve 53 and a fourth air valve 54, which can regulate the exhaust channel 8 from the heat dissipation end of each corresponding module to the common exhaust fan 3, adjust the opening and closing of the exhaust path, meet the cooling needs in different environments, and make the system operate more flexibly and efficiently.

[0058] Furthermore, the third air valve 53 opens and closes synchronously with the first air valve 51, that is, it simultaneously closes or opens the air supply and exhaust of the evaporative cooling module 1. When closed, the shared air supply fan 4 and the shared exhaust fan 3 can independently provide air supply for the operation of the compression refrigeration module 2, ensuring the stable refrigeration of the compression refrigeration module 2.

[0059] The second air valve 52 and the fourth air valve 54 open and close synchronously. Similarly, the second air valve 52 and the fourth air valve 54 control the air supply and exhaust of the compression refrigeration module 2. When the compression refrigeration module 2 is closed, the second air valve 52 and the fourth air valve 54 close synchronously, so that the shared air supply fan 4 and the shared exhaust fan 3 can independently provide the operation of the evaporative cooling module 1, reducing energy consumption and providing energy-saving and environmental protection benefits.

[0060] By opening and closing the third air valve 53 simultaneously with the first air valve 51, and the second air valve 52 simultaneously with the fourth air valve 54, the evaporative cooling module 1 and the compression refrigeration module 2 of the composite air conditioning system can work independently without interfering with each other, achieving stable switching between different cooling modes and allowing for selection of different cooling effects according to environmental requirements.

[0061] Furthermore, when the air valve group 5 simultaneously opens the first air valve 51, the second air valve 52, the third air valve 53, and the fourth air valve 54, the evaporative cooling module 1 and the compression refrigeration module 2 can operate synchronously. When operating synchronously, a composite cooling effect is produced, that is, the cooling effect of both the evaporative cooling module 1 and the compression refrigeration module 2 is achieved. However, in this mode, neither the evaporative cooling module 1 nor the compression refrigeration module 2 will use high power. This method prevents the compression refrigeration module 2 from using excessively high power, thereby reducing energy consumption. Together with the evaporative cooling module 1, it can also provide stable cooling air, allowing the composite air conditioning system to adapt to the environment according to demand. At the same time, by utilizing the energy-saving and environmentally friendly characteristics of the evaporative cooling module 1 and the stable cooling characteristics of the compression refrigeration module 2, a stable and efficient cooling effect can be provided under different climatic conditions.

[0062] Therefore, the opening and closing of the air valve group 5 can allow the evaporative cooling module 1 to operate independently or the compression refrigeration module 2 to operate independently, or allow the evaporative cooling module 1 and the compression refrigeration module 2 to operate synchronously. The operating mode can be determined according to environmental requirements to achieve the effect of environmental adaptability.

[0063] In some embodiments, reference Figure 3 As shown, a dehumidification channel 62 is provided between the two sets of air inlet channels 6 of the evaporative cooling module 1. The dehumidification channel 62 can also be a rectangular air duct, and the dehumidification channel 62 is located on one side of the air inlet channel 6 in a T-shaped channel. The two sides of the T can connect the two sets of air inlet channels 6, and the end is connected to the air supply channel 7. Specifically, the position of the air supply channel 7 is located between the second air valve 52 and the cooling end of the compression refrigeration module 2. The function of the dehumidification channel 62 is to deliver cold air to dehumidify the air inlet channel 6 of the evaporative cooling module 1, so that the evaporative cooling module 1 can also be used in environments with high humidity.

[0064] The dehumidification channel 62 is equipped with a fifth air valve 55. The opening and closing of the fifth air valve 55 can open or close the dehumidification channel 62, switching whether to start dehumidification of the evaporative cooling module 1.

[0065] The dehumidification mode requires the use of the compression refrigeration module 2, but only a small or minimum power is needed to generate some cold air, which reduces energy consumption and operating costs.

[0066] Specifically, the cooling effect of the evaporative cooling module 1 is limited in high humidity environments. Therefore, when encountering a high humidity environment, the second air valve 52 is closed and the fifth air valve 55 is opened. After the second air valve 52 is closed, the cooling end of the compression cooling module 2 is opened. At this time, it is not necessary to use a large power. It is only necessary to start the compression cooling module 2 at a small or minimum power. Only the slight cold air generated by the compression cooling module 2 is needed. Because the second air valve 52 of the air supply channel 7 is closed, the cold air can only be delivered from the dehumidification channel 62 to the air inlet channel 6 of the evaporative cooling module 1, where it mixes with the moisture in the air inlet channel 6. The moisture will condense into water droplets and adhere to the surface of the air inlet channel 6 under the influence of the cold air, thereby reducing the impact of moisture on the evaporative cooling module 1.

[0067] If the first air valve 51, the second air valve 52, the third air valve 53 and the fourth air valve 54 are opened simultaneously in the air valve group 5, the evaporative cooling module 1 and the compression refrigeration module 2 will operate synchronously. In this case, the fifth air valve 55 needs to be closed to close the dehumidification channel 62 and prevent the air inlet channel 6 from connecting with the air outlet channel 7 to avoid crossflow.

[0068] Further reference Figure 4As shown, the air inlet channel 6 of the evaporative cooling module 1 is equipped with two dehumidifying plates 63. The dehumidifying plates 63 can be made of thin metal plates, which can fully contact the cold air, thereby reducing the temperature of the dehumidifying plates 63. When humid air enters the air inlet channel 6, it first contacts the dehumidifying plates 63. After contacting the dehumidifying plates 63 with the reduced temperature, the moisture condenses into water droplets and adheres to the dehumidifying plates 63, thereby achieving the function of dehumidifying the humid air.

[0069] Two dehumidifying plates 63 are tilted in different directions and spaced apart end to end, forming a Z-shaped bend in the air intake path. Humid air flows along the tilt direction of the dehumidifying plates 63. The connection port of the dehumidification channel 62 is located between the two dehumidifying plates 63, so that the temperature of the dehumidifying plates 63 is reduced by the cold air, so as to condense and adsorb the moisture in the humid air, reduce the humidity of the humid air, and meet the air application requirements of the evaporative cooling module 1.

[0070] This method allows the evaporative cooling module 1 to adapt to different environments and still be used in humid environments. Although a compression refrigeration module 2 is used, it does not require high power. Only a small amount of cold air needs to be produced, thus reducing the required energy consumption.

[0071] Furthermore, refer to Figure 3 and Figure 4 As shown, the bottom surface of the air inlet channel 6 at the dehumidification plate 63 is inclined, and a drain pipe 64 is provided at the inclined end. The drain pipe 64 can be equipped with a removable water storage tank or a closing plug. When too much condensation accumulates, the closing plug can be opened or the water storage tank can be removed to facilitate the cleaning of the condensation.

[0072] Among them, reference Figure 4 As shown in the diagram, the arrows indicate the airflow direction. If the air intake channel 6 is tilted towards the outside, the drain pipe 64 can be installed on the side of the air intake channel 6 closer to the outside. This way, the drain pipe 64 can be installed without blocking it. During normal air intake, the drain pipe 64 can also provide air intake, and the condensed water can flow to the outside.

[0073] The specific embodiments described are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be included within the scope of protection of this application.
