Description

Technical Field

[0001] This application relates to the technical field of air conditioning equipment, and more particularly to an air conditioning system for automobile roll-on / roll-off ships. Background Technology

[0002] In the maritime operating environment, air quality is crucial to the health of the crew. Ships navigate in complex and ever-changing waters, where the surrounding air may contain large amounts of pollutants such as dust, particulate matter, harmful gases, and microorganisms. These pollutants not only reduce the freshness of the air inside the cabins and affect the comfort of the crew, but also pose potential hazards to their respiratory and cardiovascular systems. Long-term exposure to such an environment can easily lead to various respiratory diseases, allergic reactions, and other health problems.

[0003] To effectively improve air quality in shipboard cabins and protect the health of crew members, installing filters at the fresh air inlets of shipboard air conditioning systems has become a necessary and crucial measure. Filters purify the fresh air entering the air conditioning system, removing dust, particulate matter, pollen, bacteria, and other impurities, thus providing clean and healthy air for the cabins. Currently, common filter designs are typically equal in size to the cross-section of the air handling module. This design aims to ensure that the filter fully covers the fresh air inlet, maximizing the filtration effect and ensuring optimal filtration.

[0004] However, this filter design, with a cross-sectional size equal to that of the air handling module, presents a series of pressing problems in practical applications. Over long-term use, the filter gradually accumulates dust, impurities, and other contaminants, leading to decreased filtration efficiency and potentially causing poor airflow. Therefore, regular maintenance, including replacement or cleaning, is necessary. To facilitate these operations, a maintenance space equal in size to the filter must be reserved on the outside of the unit. While this space meets the filter maintenance requirements, it significantly increases the overall space occupied by the air conditioning equipment. On ships, space resources are extremely limited and precious; every area requires careful planning and rational utilization. Excessive space occupied by the air conditioning equipment not only squeezes the installation space of other important equipment and facilities, affecting the rationality and compactness of the ship's overall layout, but may also increase the ship's construction and operating costs. Utility Model Content

[0005] The purpose of this application is to provide an air conditioning device for automobile roll-on / roll-off ships, which can solve the above-mentioned problems existing in the prior art.

[0006] To achieve the above objectives, this application adopts the following technical solution: On one hand, an air conditioning device for a car roll-on / roll-off ship is provided, comprising: a body, an air handling module, and a filter. The air handling module is installed inside the body, and a movable access door is provided on the side of the body. When the access door is opened, a mounting groove located at the air inlet end of the air handling module is exposed. The filter is installed in the mounting groove, and the cross-sectional area of ​​the filter is the same as the air inlet area of ​​the air handling module. The filter is composed of at least four filter units of the same size spliced ​​together, and the four filter units are arranged in an array.

[0007] Furthermore, the filter unit includes a frame and a filter layer located inside the frame, wherein the pore size of the filter layer is between 0.1 mm and 3 mm.

[0008] Furthermore, the filter layer includes an outer first filter screen and an inner second filter screen, wherein the pore size of the first filter screen is between 1.0 mm and 3.0 mm, and the pore size of the second filter screen is between 0.1 mm and 0.5 mm.

[0009] Furthermore, the first filter screen is made of stainless steel or aluminum alloy.

[0010] Furthermore, the second filter screen is made of polyester fiber or glass fiber composite material.

[0011] Furthermore, the bottom of the frame is provided with a guide sliding part, and the top of the frame is provided with a guide sliding groove. The upper and lower filter units are guided and cooperated with each other through the guide sliding part and the guide sliding groove. The bottom surface of the mounting groove is provided with a groove that cooperates with the guide sliding part for guidance, and the top surface of the mounting groove is provided with a protrusion that cooperates with the guide sliding groove for guidance.

[0012] Furthermore, a positioning part is provided on one side of the frame, and a positioning hole is provided on the other side. The two filter units on the left and right are positioned by the positioning part and the positioning hole. The side of the mounting groove is provided with a hole that cooperates with the positioning part for positioning.

[0013] Furthermore, the frame is provided with a concealed handle on the side facing the inspection door.

[0014] Furthermore, the frame has a hidden groove on its side, and an elastic element is provided between the handle and the hidden groove. The elastic element makes the handle always tend to move away from the hidden groove.

[0015] Furthermore, the filter layer is detachably secured to the inside of the frame via magnetic snaps.

[0016] The beneficial effects of this application are as follows: A movable maintenance door is provided on the side of the unit. When maintenance of the filter is required, opening the maintenance door reveals the mounting slot located at the air inlet of the air handling module, where the filter is installed. More importantly, the filter is designed as an array structure composed of at least four filter units of the same size. In traditional designs, due to the large overall area of ​​the filter, a large space must be reserved for maintenance; however, by dividing it into multiple small units, when maintaining a single filter unit, only a small maintenance space sufficient to accommodate that single filter unit needs to be reserved on the outside of the unit, eliminating the need to reserve space for the entire large-area filter. Furthermore, the cross-sectional area of ​​the filter is consistent with the air inlet area of ​​the air handling module, ensuring that all air entering the air handling module is effectively filtered, and the filtration effect is not affected by changes in the filter structure.

[0020] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0022] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0023] like Figures 1-4 As shown, this embodiment provides an air conditioning device for a car roll-on / roll-off ship, including: a body 1, an air handling module 2, and a filter 3. The air handling module 2 is installed inside the body 1. A movable maintenance door is provided on the side of the body 1. When the maintenance door is opened, a mounting slot located at the air inlet end of the air handling module 2 is exposed. The filter 3 is installed in the mounting slot, and the cross-sectional area of ​​the filter 3 is the same as the air inlet area of ​​the air handling module 2. The filter 3 is composed of at least four filter units 301 of the same size spliced ​​together, and the four filter units 301 are arranged in an array.

[0024] In existing air conditioning systems for car carriers, the filter 3 is an integral design, requiring a maintenance space of the same size as the filter 3 to be reserved outside the hull 1 during maintenance. This results in excessive space occupation, causing numerous inconveniences to the ship's spatial layout and resource utilization. The technical solution presented in this application innovatively addresses this pain point, effectively solving the space occupation problem.

[0025] This application features a movable maintenance door on the side of the unit 1. When maintenance of the filter 3 is required, opening the maintenance door reveals the mounting slot located at the air inlet of the air handling module 2, where the filter 3 is installed. More importantly, the filter 3 is designed as an array structure composed of at least four identical filter units 301. In traditional designs, due to the large overall area of ​​the filter 3, a large space must be reserved for maintenance. However, this application breaks it down into multiple smaller units. When maintaining a single filter unit 301, only a smaller maintenance space sufficient to accommodate that single filter unit 301 needs to be reserved on the outside of the unit 1, eliminating the need to reserve space for the entire large-area filter 3. Furthermore, the cross-sectional area of ​​the filter 3 is consistent with the air inlet area of ​​the air handling module 2, ensuring that all air entering the air handling module 2 is effectively filtered, and the filtration effect is not affected by changes in the filter 3's structure.

[0026] The air conditioning equipment for car carriers provided in this application brings several significant benefits. From a space utilization perspective, traditional air conditioning equipment requires a maintenance space the same size as the filter 3 during repairs, resulting in a large overall space occupation and severely encroaching on the limited internal space of the ship. However, this application, by dividing the filter 3 into four filter units 301, only requires a smaller maintenance space outside the hull 1 to accommodate a single filter unit 301 during repairs, greatly saving space resources. This makes the internal space layout of the ship more rational and compact, providing more possibilities for the installation of other equipment and facilities, and improving the overall space utilization rate of the ship.

[0027] In terms of ease of maintenance, the modular design of the filter unit 301 makes maintenance simpler and more efficient. When a filter unit 301 malfunctions or needs cleaning, only that unit needs to be disassembled for processing, eliminating the need for complete replacement or processing of the large-area filter 3 as in traditional designs. This reduces maintenance costs and time, and improves maintenance efficiency. Simultaneously, the design of the filter 3's cross-sectional area being consistent with the air intake area of ​​the air handling module 2 ensures that the air entering the air conditioning system is adequately and effectively filtered, creating a clean and healthy air environment inside the car carrier and effectively protecting the safety and comfort of the crew and cargo.

[0028] Specifically, the filter unit 301 includes a frame 3011 and a filter layer 3012 located inside the frame 3011, wherein the pore size of the filter layer 3012 is between 0.1mm and 3mm. The frame 3011 provides a stable support structure for the entire filter unit 301, ensuring that the filter unit 301 maintains a fixed shape and position during installation and use, and is not prone to deformation or displacement, thereby ensuring the stability of the filtration effect. The filter layer 3012 is the core part of the filter unit 301, and its pore size is between 0.1mm and 3mm. When air passes through the filter unit 301, dust, particulate matter, and other impurities in the air are intercepted according to the relationship between their size and the pore size of the filter layer 3012. The filter layer 3012 with a smaller pore size can intercept finer particles, while the filter layer 3012 with a larger pore size allows relatively larger particles to pass through, but will intercept larger impurities. By reasonably setting the pore size range of the filter layer 3012, it is possible to effectively filter impurities of different particle sizes, making the air entering the air conditioning equipment cleaner.

[0029] More specifically, the filter layer 3012 includes an outer first filter screen and an inner second filter screen. The pore size of the first filter screen is between 1.0mm and 3.0mm, and the pore size of the second filter screen is between 0.1mm and 0.5mm. When air enters the filter unit 301, it passes through these two filter screens sequentially. The outer first filter screen, with a pore size between 1.0mm and 3.0mm, is designed to primarily perform preliminary filtration. When air flows through the first filter screen, larger particles such as leaf fragments, large dust particles, and insects, being larger than the pore size of the first filter screen, are intercepted on its surface and cannot proceed to subsequent filtration stages. This preliminary filtration process effectively reduces the number of large particles entering the second filter screen, thus reducing its filtration burden. The inner second filter screen, with a pore size between 0.1mm and 0.5mm, has a smaller pore size than the first filter screen, enabling finer filtration. Although large particles of impurities have been removed from the air after the initial filtration by the first filter, it may still contain some fine dust, pollen, smoke particles, and other tiny pollutants. These tiny pollutants are smaller than the pore size of the first filter but larger than or equal to the pore size of the second filter. When the air passes through the second filter, these tiny pollutants are intercepted, thus ensuring that the air entering the air conditioning unit is cleaner and purer.

[0030] Optionally, the first filter screen is made of stainless steel or aluminum alloy, and the second filter screen is made of polyester fiber or glass fiber composite material. The first filter screen, made of stainless steel or aluminum alloy, possesses high strength and corrosion resistance. During airflow, when large particles (such as leaves, large dust particles, etc.) collide with the first filter screen, the robust structure of the stainless steel or aluminum alloy can withstand the impact without easily deforming or being damaged, ensuring that the filter screen maintains a stable filtration shape and pore size, continuously and effectively intercepting large particles. Simultaneously, its corrosion resistance allows it to withstand the erosion of moisture, salt, and other corrosive substances in the complex environment of a ship, extending its service life.

[0031] The second filter, made of polyester or glass fiber composite material, features a rich fiber structure and excellent adsorption properties. Fine particulate matter (such as pollen and smoke particles) carried by the air initially filtered by the first filter enters the second filter and is adsorbed by the gaps and surfaces between the fibers. The fine and uniformly distributed fibers of the polyester or glass fiber composite material form complex filtration channels, increasing the contact area with airborne particles, thus more efficiently capturing and intercepting fine particulate matter and further improving air purification.

[0032] In some embodiments, the bottom of the frame 3011 is provided with a guide sliding part 3013, and the top of the frame 3011 is provided with a guide sliding groove 3014. The upper and lower filter units 301 are guided and engaged by the guide sliding part 3013 and the guide sliding groove 3014. The bottom surface of the mounting groove is provided with a groove that cooperates with the guide sliding part 3013 for guidance, and the top surface of the mounting groove is provided with a protrusion that cooperates with the guide sliding groove 3014 for guidance. When installing the filter unit 301, the guide sliding part 3013 at the bottom of the first filter unit 301 is aligned with the groove on the bottom surface of the mounting groove, and the filter unit 301 is pushed along the groove direction. The guide sliding part 3013 slides in the groove, playing a guiding role and ensuring that the filter unit 301 can enter the mounting groove along a predetermined straight direction. After the first filter unit 301 is installed, when installing the second filter unit 301, the guide sliding part 3013 at the bottom of the second filter unit 301 is aligned with the guide sliding groove 3014 at the top of the first filter unit 301, and the guide sliding groove 3014 at the top of the second filter unit 301 is aligned with the protrusion on the top surface of the mounting groove. During the process of pushing the second filter unit 301, the guide sliding part 3013 and the guide sliding groove 3014 cooperate with each other, and the guide sliding groove 3014 cooperates with the protrusion, thus forming a precise guiding relationship between the two filter units 301 and between the filter unit 301 and the mounting groove. This guiding cooperation restricts the horizontal displacement of the filter unit 301, allowing it to move only along a predetermined sliding direction, thereby ensuring that the filter unit 301 can be accurately and smoothly installed into the designated position within the mounting groove.

[0033] Meanwhile, one side of the frame 3011 is provided with a positioning part 3015, and the other side is provided with a positioning hole 3016. The two filter units 301 are positioned together by the positioning part 3015 and the positioning hole 3016. The side of the mounting groove is provided with a hole that cooperates with the positioning part 3015 for positioning. When installing the filter unit 301, the first filter unit 301 is placed in the mounting groove, and its side positioning part 3015 is aligned with the hole on the side of the mounting groove and inserted. At this time, the positioning part 3015 and the hole fit together, which plays a preliminary positioning role for the filter unit 301 in the horizontal direction (left and right direction) and restricts its left and right movement. Then, the adjacent second filter unit 301 is installed. The side of the second filter unit 301 with the positioning hole 3016 is aligned with the side of the first filter unit 301 with the positioning part 3015. Then, the second filter unit 301 is pushed so that the positioning part 3015 of the first filter unit 301 is inserted into the positioning hole 3016 of the second filter unit 301. Through the cooperation of the positioning part 3015 and the positioning hole 3016, the two filter units 301 on the left and right sides are precisely connected, which further restricts the relative displacement between them and ensures that multiple filter units 301 can be neatly arranged and tightly fitted in the mounting groove.

[0034] Furthermore, a concealed handle 3017 is provided on the side of the frame 3011 facing the access door. The working principle of this concealed handle 3017 is primarily based on ergonomic and space utilization considerations. The concealed handle 3017 typically employs a special structural design so that, when not in use, it remains flush or nearly flush with the side of the frame 3011, not protruding from the frame 3011 surface. This avoids interference with the surrounding space during normal operation of the air conditioning equipment and does not affect the overall aesthetics of the equipment. When the filter unit 301 needs to be installed, removed, or maintained, the operator can unfold or pop out the concealed handle 3017 using specific operating methods (such as pressing, sliding, rotating, etc., depending on the design of the handle 3017), creating a gripping structure. At this time, the operator can hold the handle 3017 and apply a certain pulling or pushing force to easily pull the filter unit 301 out of the mounting slot or push it in, so as to realize convenient operation of the filter unit 301.

[0035] Specifically, the frame 3011 has a hidden groove on its side, and an elastic element is provided between the handle 3017 and the hidden groove. The elastic element ensures that the handle 3017 always tends to move away from the hidden groove. When the air conditioning equipment is operating normally and the filter unit 301 does not need to be operated, the handle 3017 is in a hidden state. At this time, due to the action of the elastic element, although the handle 3017 is subjected to an outward force, it is fixed in the hidden groove by the structural constraints of the hidden groove (such as the locking structure or limiting protrusion at the edge of the hidden groove), remaining flush or nearly flush with the side of the frame 3011, and will not protrude from the surface of the frame 3011. This avoids interfering with the surrounding space and ensures the overall aesthetics of the equipment and the rationality of the spatial layout.

[0036] When maintenance of the filter unit 301 is required, such as for installation, disassembly, or cleaning, the operator simply applies a force (usually a pressing force into the concealed groove) to the handle 3017 in the opposite direction to the elastic force of the elastic element, overcoming the elastic force and separating the handle 3017 from the fixing structure of the concealed groove. Then, under the action of the elastic force, the handle 3017 will automatically move in the direction of disengagement from the concealed groove, popping out to a certain position, forming a structure that the operator can grip. After gripping the handle 3017, the operator can easily move the filter unit 301. After completing the operation, pressing the handle 3017 back into the concealed groove will fix the handle 3017 in place again, restoring it to its concealed state.

[0037] Specifically, the filter layer 3012 is detachably secured to the inside of the frame 3011 via magnetic fasteners. The magnetic fasteners typically consist of two parts: one part is installed at the edge of the filter layer 3012, and the other part is installed at a corresponding position inside the frame 3011. At least one part of these two fastener parts contains a magnetic material (such as a permanent magnet), and the other part can be a magnetically attracted metal material (such as iron, nickel, etc.), or it can also contain a magnetic material but with opposite polarities to achieve mutual attraction.

[0038] When the filter layer 3012 needs to be installed inside the frame 3011, the operator only needs to roughly align the filter layer 3012 with the installation position inside the frame 3011. Due to the magnetic attraction between the magnetic fasteners, the filter layer 3012 will automatically move closer to the frame 3011 and be precisely positioned. As the distance between the filter layer 3012 and the frame 3011 gradually decreases, the attraction between the magnetic fasteners will rapidly increase, eventually causing the filter layer 3012 to be firmly attached to the inside of the frame 3011, completing the installation process.

[0039] When the filter layer 3012 needs to be disassembled for cleaning, replacement, or other maintenance operations, the operator only needs to apply a certain amount of external force to overcome the magnetic attraction between the magnetic fasteners, and the filter layer 3012 can be easily removed from the inside of the frame 3011. Due to the magnetic adsorption properties, the disassembly process does not require complicated tools or cumbersome operating procedures, making the operation simple and convenient.
