Description

Technical Field

[0001] This invention relates to the field of heat exchanger technology, and more specifically, to a structure and vessel for carrying an air conditioner in the driver's cab. Background Technology

[0002] As the control center of a cruise ship, the comfort of its interior environment significantly impacts crew efficiency and navigational safety. The air conditioning system is the core equipment for ensuring the thermal and humidity environment and air quality of the bridge. Currently, existing cruise ship bridge air conditioning systems typically employ a "top-supply, top-return" airflow organization. Specifically, the main supply air ducts and return air ducts are laid within the ceiling mezzanine above the bridge ceiling, connecting to various air distributors and return air grilles. To achieve full-area air supply and return coverage, numerous supply and return air branch pipes and corresponding air vents need to be installed at the top of the ceiling.

[0003] Air distributors are typically concentrated in a limited area at the top of the ceiling. After entering the room, the air jet is easily deflected and turbulent due to obstructions from the building structure or other obstacles. In actual use, the control area often experiences localized excessive or insufficient airflow, making it difficult to achieve a uniform temperature distribution throughout the cab. Furthermore, because the air jet mixes with the indoor air at the ceiling, when the supply air temperature is low, the surface temperature of the air distributor's metal chassis can easily fall below the dew point temperature of the indoor air, leading to condensation on the distributor's chassis surface. This condensation can drip onto the cab floor or instruments, affecting the cab's aesthetics and posing a safety hazard of short circuits in electrical equipment.

[0004] Return air grilles typically have only a few point-like return air inlets at the top. Stale air in the breathing and activity areas of the cab needs to rise to ceiling height before being drawn in. This airflow organization results in low air exchange efficiency in the lower part of the cab, where pollutants tend to remain at breathing height. Summary of the Invention

The pore size of the first filter screen is larger than the pore size of the second filter screen.

[0010] In some optional embodiments, the cross-sectional height of the sealing interlayer forming the air supply static pressure zone gradually decreases along the airflow direction of the air conditioning system.

Detailed Implementation

[0019] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0021] As the control center of a cruise ship, the comfort of its interior environment significantly impacts crew efficiency and navigational safety. The air conditioning system is the core equipment for ensuring the thermal and humidity environment and air quality of the bridge. Currently, existing cruise ship bridge air conditioning systems typically employ a "top-supply, top-return" airflow organization. Specifically, the main supply air ducts and return air ducts are laid within the ceiling mezzanine above the bridge ceiling, connecting to various air distributors and return air grilles. To achieve full-area air supply and return coverage, numerous supply and return air branch pipes and corresponding air vents need to be installed at the top of the ceiling.

[0022] Air distributors are typically concentrated in a limited area at the top of the ceiling. After entering the room, the air jet is easily deflected and turbulent due to obstructions from the building structure or other obstacles. In actual use, the control area often experiences localized excessive or insufficient airflow, making it difficult to achieve a uniform temperature distribution throughout the cab. Furthermore, because the air jet mixes with the indoor air at the ceiling, when the supply air temperature is low, the surface temperature of the air distributor's metal chassis can easily fall below the dew point temperature of the indoor air, leading to condensation on the distributor's chassis surface. This condensation can drip onto the cab floor or instruments, affecting the cab's aesthetics and posing a safety hazard of short circuits in electrical equipment.

[0023] Return air grilles typically have only a few point-like return air inlets at the top. Stale air in the breathing and activity areas of the cab needs to rise to ceiling height before being drawn in. This airflow organization results in low air exchange efficiency in the lower part of the cab, where pollutants tend to remain at breathing height.

[0024] This application provides a structure and vessel for mounting an air conditioner in the driver's cab to solve problems such as uneven air supply and return, large ductwork requirements, unsightly top air vents, and lack of air purification and disinfection functions. The following description refers to the accompanying drawings. Figures 1-2 A detailed description is provided of the structure that houses the air conditioner in the driver's cab.

[0025] This application provides a structure for an air conditioner mounted in a driver's cab. The structure includes: a sealed interlayer 1, disposed below the driver's cab floor, with an airflow channel layer 2 forming an air conditioning air passage inside the sealed interlayer 1. The airflow channel layer 2 is divided into a mutually isolated supply air static pressure area 251 and a return air collection area 252. The supply air static pressure area 251 is connected to the air supply outlet of the air conditioner, and the return air collection area is connected to the return air outlet of the air conditioner. An air supply outlet is disposed on the side wall or floor of the driver's cab and is connected to the supply air static pressure area 251 of the sealed interlayer 1, for delivering air conditioning air to the interior of the driver's cab. A return air inlet is disposed on the side wall or floor of the driver's cab and is connected to the return air collection area 252 of the sealed interlayer 1, for delivering return air from the interior of the driver's cab back to the air conditioner.

[0026] Specifically, the entire bottom sealed interlayer 1 directly serves as the main airflow channel layer 2. The airflow channel layer 2, formed within the sealed interlayer 1, is divided into mutually isolated supply air static pressure zones 251 and return air collection zones 252. The supply air static pressure zone 251 is connected to the air outlet of the air conditioner, allowing direct airflow to each zone. This eliminates the need for ceiling-mounted air distributors and return air grilles, resulting in a clean and tidy cab ceiling, enhancing visual appeal and spaciousness. The elimination of numerous independent ductwork significantly simplifies the piping system. The air outlets are located on the side walls or floor of the cab, areas far from cold bridges where the outlet surface temperature is closer to the lower interior temperature. Furthermore, the supply air static pressure zone 251 within the interlayer is isolated from the return air zone, effectively preventing condensation from forming as hot and cold air converges within the interlayer. The sealed interlayer 1 has a large regular space and is located on the necessary path of airflow before entering the cab. By setting up a primary filter, a high-efficiency filter and an ultraviolet disinfection device in the air supply static pressure area 251 of the sealed interlayer 1, all the supplied air can be efficiently purified without occupying the effective space in the cab, thus ensuring the cleanliness of the air in the cab.

[0027] In some optional embodiments, the structure of the sealing interlayer 1 includes a load-bearing base layer 11, a fireproof and sound-insulating layer 12, an airflow channel layer 2, and an isolation and waterproof layer 14 arranged sequentially from bottom to top. The fireproof and sound-insulating layer 12 is laid on top of the bottom load-bearing base layer 11, the airflow channel layer 2 is located above the fireproof and sound-insulating layer 12, the isolation and waterproof layer 14 is disposed above the airflow channel layer 2, and the cab floor layer is disposed above the isolation and waterproof layer 14.

[0028] Specifically, the load-bearing base layer 11 is a ship's steel deck coated with an epoxy anti-rust coating, supporting all equipment. The fireproof and soundproof layer 12 includes a fireproof layer and a soundproof layer, which are stacked. The fireproof layer is made of rock wool or ceramic fiber board with a thickness of ≥50cm. The soundproof layer is made of sound-dampening felt, laid on top of the rock wool or ceramic fiber board to absorb noise from the air conditioning fan and airflow. The airflow channel layer 2 is cylindrical, allowing airflow to pass through. It is divided into an isolated supply air static pressure area 251 and a return air collection area 252. The supply air static pressure area 251 is connected to the air supply vent of the air conditioner, and the return air collection area is connected to the return air vent of the air conditioner. A galvanized steel plate or aluminum alloy plate is used as the base plate 21 of the airflow channel layer 2, laid on top of the sound-dampening felt. Sound-absorbing cotton is pasted on the inner surface of the sidewalls of the airflow channel layer 2 to prevent wind noise.

[0029] In some optional embodiments, the airflow channel layer 2 includes an intermediate isolation layer 23, which divides the airflow channel layer 2 into a cable layer 24 and a duct layer 25. The cable layer 24 is close to the fireproof and soundproof layer 12, and the duct layer 25 is close to the waterproof isolation layer 14. The duct layer 25 is divided into mutually isolated supply air static pressure area 251 and return air collection area 252.

[0030] Specifically, the airflow channel layer 2 is provided with an intermediate isolation layer 23, which divides the airflow channel layer 2 into a cable layer 24 and an air duct layer 25 along the thickness direction. The cable layer 24 is located below the intermediate isolation layer 23, close to the fireproof and soundproof layer 12, and is used for laying cable trays and cables. The air duct layer 25 is located above the intermediate isolation layer 23, close to the waterproof isolation layer 14. The air duct layer 25 is provided with a longitudinal partition plate 3, which divides the air duct layer 25 into a cable layer 24 and an air duct layer 25. The air static pressure zone 251 and the return air collection zone 252 are divided into a supply air static pressure zone 251 and a return air collection zone 252. The airflow channel layer 2 uses galvanized steel plate or aluminum alloy plate as the base plate 21 of the airflow channel layer 2. The galvanized steel plate or aluminum alloy plate is laid on top of the sound insulation damping felt. A cable layer 24 is formed between the intermediate isolation layer 23 and the base plate 21 of the airflow channel layer 2. A duct layer 25 is formed between the intermediate isolation layer 23 and the isolation waterproof layer 14. The duct layer 25 is divided into a mutually isolated supply air static pressure zone 251 and a return air collection zone 252.

[0031] Furthermore, the cable layer 24 and the air duct layer 25 are completely physically isolated by the intermediate isolation layer 23. Even if condensation or water accumulation occurs in the air duct layer 25, the condensate is blocked by the isolation layer and cannot contact the cable layer 24, thus structurally eliminating potential electrical safety hazards. The cables are laid in the air duct layer 25, utilizing the structural strength of the ship's deck itself to support the cable trays. Cable laying is convenient and does not occupy any space inside the wheelhouse. The air duct layer 25 is located above the cable layer 24 and connects to the air outlet end, minimizing the airflow path and wind resistance. A fireproof isolation layer is laid above the intermediate isolation layer 23. A first fireproof isolation layer 22 is laid on the bottom plate 21 of the airflow channel layer 2, and a second fireproof isolation layer 231 is laid above the intermediate isolation layer 23. If a fire occurs in the cable layer 24, the flames can directly ignite the duct insulation material and spread rapidly to the entire air conditioning system and even adjacent compartments through the air duct. After the first fireproof isolation layer 22 is set up, even if the cable layer 24 catches fire, the flames and high-temperature smoke will be blocked by the isolation layer for at least 30-60 minutes, which will buy valuable time for personnel evacuation and fire fighting.

[0032] In some optional embodiments, the sealing interlayer 1 further includes a partition plate 3, which is disposed inside the air duct layer 25 and connects the intermediate isolation layer 23 and the isolation waterproof layer 14 respectively, so as to divide the air duct layer 25 into mutually isolated supply air static pressure area 251 and return air collection area 252.

[0033] Specifically, the air duct layer 25 is physically divided into an independent supply air static pressure zone 251 and a return air collection zone 252 by the partition plate 3. This structurally forces the separation of supply and exhaust air, ensuring that all supply air must first enter the cab, complete the indoor heat and humidity exchange, and then flow back to the return air zone, thus preventing airflow short-circuiting.

[0034] The partition plate 3 divides the air duct layer 25 into an independent supply air static pressure zone 251 and a return air collection zone 252. Within the supply air static pressure zone 251, a pre-filter, a high-efficiency filter, an ultraviolet disinfection device, and a negative ion generator can be sequentially installed. This ensures that the supply air static pressure zone 251 is a closed, clearly defined processing channel. All air entering this zone must pass through the air supply terminal into the driver's cab, and is completely purified during this process. This guarantees 100% filtration and disinfection of the supply air, ensuring reliable purification. When the air conditioning supply air enters a sealed, volumetric supply air static pressure zone 251, the air velocity rapidly decreases, and the pressure tends to become uniform. At this point, the pressure at each air outlet within the supply air static pressure zone 251 is essentially equal.

[0035] In some optional embodiments, the sealing interlayer 1 further includes a filter component disposed at the inlet of the air supply static pressure zone 251. The filter component includes a support frame, a first filter screen, and a second filter screen. The support frame is provided with a first filter groove and a second filter groove in sequence in the direction of gas flow. The first filter groove is used to limit the first filter screen, and the second filter groove is used to limit the second filter screen. The pore size of the first filter screen is larger than the pore size of the second filter screen.

[0036] Specifically, the support frame is fixedly installed at the inlet section of the air supply static pressure zone 251, and its outer periphery is sealed to the inner wall of the duct layer 25. The support frame has a first limiting groove and a second limiting groove sequentially opened along the gas flow direction. The first filter screen is inserted into the first limiting groove for positioning and fixing, and the second filter screen is inserted into the second limiting groove for positioning and fixing. The first filter screen is a pre-filter with a filtration level of G3 or G4, used to intercept particles with a diameter greater than or equal to 5μm. The second filter screen is a medium-efficiency filter or a high-efficiency filter, used to intercept particles with a diameter greater than or equal to 0.5μm.

[0037] Furthermore, an openable inspection cover is provided above the support frame, allowing the first and second filters to be vertically pulled out from the inspection cover along the first and second limiting grooves. A sealing strip is provided between the support frame and the first and second filters to prevent unfiltered air from bypassing and leaking through the gaps between the filters and the support frame.

[0038] In some optional embodiments, the cross-sectional height of the air supply static pressure region 251 formed by the sealing interlayer 1 gradually decreases along the airflow direction of the air conditioning system. The cross-sectional height of the air supply static pressure region 251 is equal to the height of the partition plate 3, and the formula for the cross-sectional height of the air supply static pressure region 251 is:

[0039] in, To be at the distance from the air duct inlet Cross-sectional height (m) at the location; The initial height at the entrance (m); The initial flow velocity at the inlet is (m / s). The average flow velocity (m / s) at the location gradually decreases along the path.

[0040] Specifically, as air is continuously discharged from the air supply holes along the way, the flow rate in the main air duct gradually decreases. In order to maintain a consistent static pressure before the air supply holes, the flow velocity... It needs to be kept within the design range of 1.5~2.5m / s.

[0041] In some optional embodiments, an ultraviolet disinfection component is also included, disposed downstream of the filter component in the direction of gas flow in the air supply static pressure zone 251.

[0042] Specifically, the air entering the ultraviolet irradiation area has been pre-treated to remove dust, aerosols, and other particulate matter. Ultraviolet light can directly irradiate airborne microorganisms without penetrating particulate barriers, significantly improving disinfection efficiency. The sequence of filtration followed by irradiation ensures that the air reaching the ultraviolet lamp irradiation area is clean and transparent, allowing the ultraviolet light to act on airborne bacteria, viruses, and mold spores with almost no attenuation, achieving a sterilization rate of over 99.9%.

[0043] Furthermore, the ultraviolet disinfection component includes an ultraviolet lamp and a lamp bracket. The lamp bracket is fixedly installed on the inner wall of the air supply static pressure zone 251, and the ultraviolet lamp is installed on the lamp bracket. The ultraviolet lamp extends along the width direction of the air supply static pressure zone 251 to cover the entire air supply cross section.

[0044] In some optional embodiments, a negative oxygen ion generator is also included, disposed in the air supply static pressure zone 251, downstream of the ultraviolet disinfection component in the direction of gas flow, for releasing negative oxygen ions into the air conditioning air or indoor air.

[0045] Specifically, negative oxygen ions have a comprehensive effect of settling dust, neutralizing positive ions, and improving human physiological functions, which can significantly improve the air quality in the cab and the comfort of the crew. Negative oxygen ions carry a negative charge and can electrostatically adsorb positively charged particulate matter such as dust, smoke, and bacteria in the air, causing them to agglomerate into larger particles and settle. This complements the physical filtration of the air conditioner, further reducing the concentration of suspended particulate matter indoors.

[0046] Furthermore, the negative ion generator includes a power module and a discharge electrode. The power module is fixedly installed in the cable layer 24, and the discharge electrode extends into the interior of the air supply layer. The power module is electrically connected to the discharge electrode via a wire. The discharge electrode is a carbon fiber brush electrode or a needle-tip array electrode, with the discharge end of the electrode facing the airflow direction or perpendicular to the airflow direction.

[0047] Furthermore, the distance between the negative ion generator and the ultraviolet disinfection component is greater than or equal to 200 mm to prevent ultraviolet rays from interfering with or accelerating the decay of negative ions.

[0048] In some optional embodiments, the load-bearing base layer 11 includes a base plate 111, a first side plate 112 and a second side plate 113. The first side plate 112 and the second side plate 113 are located on both sides of the base plate 111 in the width direction to form a groove structure. The fireproof and soundproof layer 12 is laid on the load-bearing base layer 11, and the isolation and waterproof layer 14 is fastened to the first side plate 112 and the second side plate 113 to form an airflow channel layer 2.

[0049] Specifically, the base plate 111, first side plate 112, and second side plate 113 of the load-bearing base layer 11 form an integrated U-shaped groove structure. The fireproof and soundproof layer 12 can be directly laid in the groove of the load-bearing base layer 11. The isolation and waterproof layer 14 is fastened from above to form a closed airflow channel layer 2, realizing modular and rapid assembly. The base plate 111 serves as the bottom plate of the entire sealed interlayer 1, and the first side plate 112 and second side plate 113 serve as side walls. The base plate 111, first side plate 112, and second side plate 113 are fixedly connected to form an integral groove-shaped component. The fireproof and soundproof layer 12 can be directly laid in the U-shaped groove. The isolation and waterproof layer 14 covers the opening of the U-shaped groove, and the two ends of the isolation and waterproof layer 14 in the width direction are respectively sealed to the upper end of the first side plate 112 and the upper end of the second side plate 113 to seal the internal space of the U-shaped groove to form the airflow channel layer 2. The first side plate 112 and the second side plate 113 are fixed to the base plate 111 by continuous welding or bolt connection, and the height of the first side plate 112 and the second side plate 113 is 200-300mm to match the design height of the airflow channel layer 2.

[0050] Furthermore, the upper surfaces of the first side plate 112 and the second side plate 113 are provided with sealing grooves, and elastic sealing strips are embedded in the sealing grooves. The two ends of the isolation waterproof layer 14 are inserted into the sealing grooves and pressed against the elastic sealing strips to achieve airtight sealing.

[0051] Furthermore, the base plate 111, the first side plate 112, and the second side plate 113 are all galvanized steel plates or marine corrosion-resistant aluminum alloy plates, with a thickness of not less than 3mm, to ensure structural strength and corrosion resistance.
