[0002] With rapid economic development, the cruise ship industry has grown significantly, and the occupancy of passenger space on cruise ships has shown a gradual upward trend. Therefore, the energy consumption of air conditioning and thermal comfort on cruise ships are crucial issues. Cruise ships operate on open water, and in hot weather, the lack of external shelter can cause the temperature inside the cabin to rise rapidly, affecting the recreational activities and work of crew and passengers, and even posing significant safety hazards. Traditional split-type air conditioners are commonly used for air conditioning on cruise ships. While they provide a comfortable artificial environment for crew, they inherently suffer from low thermal comfort and high energy consumption, hindering sustainable development. Furthermore, traditional split-type air conditioners have limited cooling system functionality and cannot guarantee the freshness of food and seafood caught during recreational fishing trips. To lower the cabin temperature while maintaining the freshness of food and seafood, additional refrigeration and preservation equipment is required, occupying space and increasing the ship's weight, thus increasing the energy consumption required for propulsion.

Detailed Implementation

[0020] To better explain and facilitate understanding of the present invention, a detailed description of the invention is provided below with reference to the accompanying drawings and specific embodiments. In this document, directional terms such as "upper," "lower," etc., are used interchangeably with respect to... Figure 1 The orientation is used as a reference.

[0021] While exemplary embodiments of the invention are shown in the accompanying drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the invention can be understood more clearly and thoroughly, and that the scope of the invention can be fully conveyed to those skilled in the art.

[0022] like Figure 1-10 As shown, this invention provides a marine integrated energy system that combines refrigeration, cooling, and heating. This system is applied to small and medium-sized cruise ships, especially yachts. It integrates an air conditioning system and a refrigerator system, which not only meets daily heating and cooling needs, but also provides cooling for the refrigerated compartments. This ensures the freshness of food for the crew and aquatic products caught during recreational fishing trips. There is no need to add additional refrigeration and preservation equipment, which reduces the space occupied by the hull, reduces the weight of the hull, and thus reduces the energy consumption of the boat.

[0023] Specifically, see Figure 1 The marine integrated energy system combining refrigeration, cooling, and heating includes a refrigeration, cooling, and heating system, a comfort terminal system, an air detection and control system, and an auxiliary energy supply system. The refrigeration, cooling, and heating system comprises a compression module 11, a throttling module 12, a condensing module 13, a refrigeration evaporation module 14, and an air conditioning evaporation module 15, all connected by refrigerant piping. These modules are all prefabricated within the hull, making full use of the limited space inside the hull, optimizing the structure of the ship's air conditioning system, and reducing the system's occupancy rate within the hull.

[0024] The condenser module 13 is mounted on the top of the hull. As the boat moves, ambient air passes through the condenser module 13 for heat exchange, reducing the aerodynamic time of the fan and thus lowering system energy consumption. The air conditioning evaporator module 15 regulates the temperature inside the cabin, providing a comfortable environment for the crew. The refrigeration evaporator module 14 cools the refrigerated compartment, ensuring the freshness of food and seafood caught during recreational fishing, thus improving the user experience.

[0025] See Figure 1 The air detection and control system is prefabricated and installed inside the hull, reducing the space required for installation. The comfort terminal system is embedded in the hull wall and installed according to the actual structure of the cabin to improve the comfort of the crew. The air detection and control system is connected to the comfort terminal system. The condenser module 13 is connected to the air detection and control system for heat exchange, transferring the heat or cold from the condenser module 13 to the air detection and control system, and then delivering cool or warm air to the cabin through the comfort terminal system. Compared with traditional split-type air conditioning indoor units, the installation location of the comfort terminal system is more flexible, avoiding direct contact between the airflow and the crew's skin, improving thermal comfort, preventing drowsiness caused by high-speed warm air, and improving the crew's alertness and work efficiency.

[0026] Furthermore, the auxiliary power supply system includes solar modules 41 installed on the hull, along with corresponding connecting lines and energy storage devices, to fully utilize the abundant solar energy resources of the unobstructed open water surface for power generation. The solar modules 41 are connected to the hull's energy supply system 16, providing auxiliary power to the energy supply system 16 and reducing energy consumption.

[0027] Compression module 11, condensing module 13, throttling module 12, and air conditioning evaporating module 15 are connected by a circulating pipeline to form the ship's cabin air conditioning system, regulating the temperature inside the cabin. Refrigeration evaporating module 14 and air conditioning evaporating module 15 are connected in parallel or series via a first pipeline. The start and stop of refrigeration evaporating module 14 and air conditioning evaporating module 15 are controlled by valves on the pipeline connecting them. When the air conditioning is cooling, the refrigerated compartment is simultaneously cooled to preserve food and aquatic products; alternatively, if no cooling is needed in the cabin, only the refrigerated compartment is cooled. Refrigeration evaporating module 14 and condensing module 13 are connected in parallel or series via a second pipeline. The start and stop of refrigeration evaporating module 14 and condensing module 13 are controlled by valves on the pipeline connecting them. In cold weather when the cabin requires heating, if cooling of the refrigerated compartment is still necessary, the refrigeration evaporating module 14 and condensing module 13 are operated in series or parallel to absorb heat for cooling, eliminating the need for additional electricity consumption and reducing cooling energy consumption. Valves are installed on the pipes connected to the refrigeration evaporation module 14 to facilitate the start and stop of the refrigeration evaporation module 14. Specifically, in hot weather, the compression module 11 includes a compressor and refrigerant piping. Sponge pads are used at the connection points to reduce noise. The gaseous refrigerant is compressed into a high-temperature, high-pressure gas after passing through the compressor, and then transported to the condensation module 13 on the top of the ship through the refrigerant piping. When the high-temperature, high-pressure refrigerant flows through the condensation module 13, the heat is carried away by the airflow, and it becomes a low-temperature, high-pressure refrigerant liquid. The throttling module 12 includes an expansion valve and refrigerant piping. The liquid refrigerant enters the throttling module 12 through the pipes. After being throttled by the expansion valve, it is then transported to the air conditioning evaporation module 15 and the refrigeration evaporation module 14. The refrigerant becomes an isothermal and isobaric gas again and enters the compression module 11 to work in a cycle, thus completing the refrigeration cycle. In cold weather, the cooling mode is switched to the heating mode through the four-way valve. The refrigeration evaporation module 14 and the condensation module 13 are connected in series to absorb heat from the refrigerant. Alternatively, the refrigeration evaporation module 14 can replace the original condensation module 13. The refrigeration evaporation module 14 uses the heat absorption characteristics of condensation to reduce the temperature inside the refrigeration compartment, ensuring that the cabin heating and refrigeration of the refrigeration compartment operate simultaneously.

[0028] In one embodiment, the refrigeration evaporation module 14 and the air conditioning evaporation module 15 are connected in series via a first pipe, employing a method such as... Figure 2 and Figure 3The diagram shows only a few key control valves. When refrigerant is not flowing through the refrigeration evaporator module 14 and the air conditioning evaporator module 15, it indicates that the valves on the pipes connecting the corresponding modules are closed, and the modules are in a closed state. When the cabin needs cooling in hot weather, the fourth valve 144 is normally closed. Condition 1: The first valve 141 is open, and the second valve 142 and the third valve 143 are closed. At this time, the refrigerant flows through the air conditioning evaporator to cool the cabin space. Condition 2: When the second valve 142 is open, and the first valve 141 and the third valve 143 are closed, the refrigerant flows through the refrigeration evaporator module 14, directly absorbing heat from the refrigeration compartment to create a low-temperature refrigerated space, while simultaneously maintaining the cooling state of Condition 1 to cool the cabin space. Condition 3: When the third valve 143 is open, and the first valve 141 and the second valve 142 are closed, the refrigerant flows through the refrigeration evaporator module 14 to maintain an even lower temperature. When heating is needed in the cabin during cold weather, adjust the four-way valve to change the refrigerant flow direction. The second valve 142 and the third valve 143 are normally closed. Condition 4: When the first valve 141 is open and the fourth valve 144 is closed, the refrigerant flows through the air conditioning evaporator module 15 to heat the cabin space. Condition 5: When the first valve 141 is open and the fourth valve 144 is open, Condition 4 is completed, heating the cabin space is provided, and Condition 3 is carried out at the same time to absorb the heat of the cold storage compartment and maintain the low temperature of the cold storage compartment.

[0029] like Figure 4 and 5 As shown, the air conditioning evaporator module 15 includes an air conditioning evaporator coil and a heat exchanger 151. The two heat exchange ends of the heat exchanger 151 are connected by pipes and are filled with water. The air conditioning evaporator coil contacts the surface of the coil or heat exchange fins at the first end of the heat exchanger 151 for heat exchange. The coil or heat exchange fins at the second end of the heat exchanger 151 can exchange heat with the air detection and control system, thereby transferring the heat or cold energy in the air conditioning evaporator module 15 to the air detection and control system. The air detection and control system then delivers the energy to the cabin through the comfort terminal system.

[0030] like Figure 5As shown, the air detection and control system includes a fan 31, a fresh air duct 32, an air heat exchange pipe 33, and an air quality detection device 34. The fresh air duct 32, fan 31, air heat exchange pipe 33, air quality detection device 34, and comfort terminal system are sequentially connected. Air flows sequentially through the fresh air duct 32, fan 31, air heat exchange pipe 33, air quality detection device 34, and comfort terminal system before entering the cabin. The second end of the heat exchanger 151 is located inside the air heat exchange pipe 33 for heat exchange with the air in the air heat exchange pipe 33. The inlet of the fresh air duct 32 is connected to a fresh air inlet 35 located outside the cabin and facing forward of the hull. A valve is installed on the fresh air duct 32. When the valve in the fresh air duct 32 is opened, if the hull is in motion, the fresh air inlet 35 faces the wind, passively introducing fresh air and reducing energy consumption; if the hull is stationary, the fan 31 actively draws in fresh air. The air monitoring and control system also includes a return air duct 36. The inlet of the return air duct 36 connects to the cabin, and the outlet connects to the inlet of the ventilation fan 31. A valve is installed on the return air duct 36. Specifically, the fan 31 draws air from the cabin, exchanges heat with the second end of the heat exchanger 151 in the air heat exchange duct 33, and then inputs it to the air quality monitoring device 34. The air quality detector 341 in the air quality monitoring device 34 detects the air temperature, humidity, PM2.5, carbon dioxide concentration, and formaldehyde concentration. When one or more of the PM2.5, carbon dioxide, and formaldehyde concentrations exceed preset values, the valve in the fresh air duct 32 is opened to introduce fresh air from outside the ship, which mixes with the indoor return air in the air heat exchange duct 33. Alternatively, the valve in the return air duct 36 is closed, using only fresh air to reduce the concentration of harmful substances in the cabin air. When the air quality reaches the standard value, the air quality detector 341 controls the fresh air valve to close, or it can actively control the opening and closing of the valve in the fresh air duct 32.

[0031] Preferably, the refrigeration evaporation module 14 includes multiple coils, which are spirally wound around the inner wall of the refrigeration compartment. The first ends of the multiple coils are all connected together, and the second ends are all connected together to improve heat exchange efficiency.

[0032] like Figure 6As shown, the condensing module 13 includes a condensing coil 131 and heat exchange fins (not shown in the figure). The two ends of the condensing coil 131 are connected to the compression module 11 and the throttling module 12, respectively. The heat exchange fins connect to the condensing coil 131 for heat exchange, increasing the heat exchange area and improving heat exchange efficiency. The solar module 41 is located on the top of the hull. The solar module 41 is a solar photovoltaic panel, the size of which can be determined according to the area of ​​the hull top, providing auxiliary power to the energy supply system 16. A space is provided between the solar module 41 and the top of the hull, within which the condensing coil 131 and heat exchange fins are housed. In open water, the solar module 41 provides shade for the condensing coil 131 and heat exchange fins below, preventing them from being exposed to direct sunlight and rapidly heating up, thus reducing heat exchange efficiency. When the hull is in motion, the air flows through the containment space and exchanges heat with the condenser coil 131 and heat exchange fins, eliminating the need for active cooling with a condenser fan. Active cooling is only required when the hull is stationary, which improves heat exchange efficiency while reducing system energy consumption.

[0033] like Figure 7-10 As shown, the comfort terminal system includes a main air duct 21 embedded in the wall of the hull, multiple warm air ducts 22, and multiple cold air ducts 23. The warm air ducts 22 and cold air ducts 23 are all connected to the main air duct 21 and are concealed within the wall. Valves are installed at the connection points to control the flow of the warm air ducts 22 and cold air ducts 23. The main air duct 21 is connected to an air detection and control system. The cold air ducts 23 are horizontally positioned near the top of the cabin. Multiple first air supply holes 24, connecting to the cabin, are formed along the length of the cold air duct 23. The diameter of the multiple first air supply holes 24 increases sequentially from the end closest to the main air duct 21 to the end furthest from the main air duct 21, ensuring that the air volume supplied by each first air supply hole 24 is the same, improving the uniformity of air supply and enhancing the comfort of the occupants in the cabin. The heating duct 22 is horizontally positioned near the bottom of the cabin. Multiple second air outlets 25, connecting to the cabin, are formed along the length of the heating duct 22. Multiple first air outlets 24 have progressively larger diameters, extending from the end closest to the main air duct 21 to the end furthest from it. Both the first and second air outlets 24 and 25 are equipped with arc-shaped baffles 26 and ultraviolet germicidal lamps 27. A slightly sloped condensate tray 28 is positioned below the cold air duct 23. During cooling, condensate drips into the slightly sloped condensate tray 28. Due to the slope, the condensate collects on one side of the tray and is discharged outside the ship. The cold air is sterilized by the ultraviolet germicidal lamps 27, improving air cleanliness. The cold air is then directed to the top of the cabin by the upward-facing arc-shaped baffles 26, diffusing at a low velocity throughout the cabin space, rapidly reducing the cabin temperature and preventing direct contact between the cold air and the human body.

[0034] Specifically, during cooling, cold air is delivered from the air detection and control system to the comfort terminal system. The valves of the cold air duct 23 open, and cold air is delivered from the upper-level cold air duct 23 to different depths within the cabin. Multiple first air outlets 24 with progressively increasing apertures ensure consistent airflow at different depths. After being sterilized by ultraviolet light, the high-speed, low-temperature air is jetted to the top of the cabin through an upward-facing arc-shaped guide plate 26. The cold air then diffuses at a lower speed throughout the cabin, preventing direct contact between the high-speed cold air and the human body, thus improving the comfort of the airflow organization. During heating, warm air... Air is delivered from the air detection and control system to the comfort terminal system. The valve in the heating duct 22 is opened, and warm air is delivered from the lower heating duct 22 to different depths of the cabin space. Multiple second air outlets 25 with progressively larger diameters ensure that the air volume is consistent at different depths. After being sterilized by ultraviolet light, the high-speed, high-temperature air is jetted to the lower position of the cabin through the downward-facing arc-shaped guide plate 26. The warm air then rises to the entire cabin space at a lower speed, avoiding the high-speed warm air blowing directly on the heads of the people in the cabin and causing dizziness, thus improving the alertness of the people in the cabin.

[0035] Furthermore, the present invention also provides an operation method for a marine integrated energy system combining refrigeration, cooling, and heating. This operation method is applied to the marine integrated energy system, and includes the following steps: The cooling mode includes three operating conditions, during which the fourth valve 144 is normally closed. In operating condition 1, the compression module 11, condensation module 13, throttling module 12 and air conditioning evaporation module 15 are connected in a loop, while the refrigeration evaporation module 14 is turned off, and only the interior of the cabin is cooled. In operating condition 2, the compression module 11, condensation module 13, throttling module 12 and air conditioning evaporation module 15 are connected in a loop, and the refrigeration evaporation module 14 and the air conditioning evaporation module 15 are connected in parallel or in series, simultaneously cooling the interior of the cabin and the refrigeration compartment. In operating condition 3, the compression module 11, condensation module 13, throttling module 12 and refrigeration evaporation module 14 are connected in a loop, the air conditioning evaporation module 15 is turned off, and only the refrigeration compartment is cooled; Operating condition four: compression module 11, condensation module 13, throttling module 12 and air conditioning evaporation module 15 are connected in a loop, refrigeration evaporation module 14 is shut down, and heating is only provided to the interior of the cabin; In operating condition 5, the compression module 11, condensation module 13, throttling module 12 and air conditioning evaporation module 15 are connected in a loop, and the refrigeration evaporation module 14 and condensation module 13 operate in series or in parallel to provide heating for the interior of the cabin and cooling for the refrigeration compartment.

[0036] like Figure 11As shown, the workflow of the refrigeration, cooling, and heating system is as follows: Step 1: Turn on the refrigeration, cooling, and heating systems; Step 2: Adjust the four-way valve to activate either the cooling mode for hot weather or the heating mode for cold weather; Step 3: In cooling mode, select one of the following operating conditions: cabin cooling starts alone, cabin cooling and refrigerated compartment cooling start simultaneously, or refrigerated compartment cooling starts alone; in heating mode, select one of the following operating conditions: heating only the cabin interior or refrigerated compartment cooling and cabin heating start simultaneously. Step 4: During high-temperature weather, the refrigerant undergoes a cooling cycle. Heat exchanger 151 absorbs heat from the chilled water return, and through heat exchange between the chilled water and indoor return air and outdoor fresh air, the cabin space is cooled. Simultaneously, the refrigerant piping directly expands into the cold storage compartment for food or aquatic products to maintain an even lower temperature. The condenser module 13, integrated with the ship's roof, discharges heat to the outdoor airflow. During low-temperature weather requiring heating, the four-way valve is adjusted to change the refrigerant flow direction. At this time, heat exchanger 151 discharges heat to the cooling water, and through heat exchange between the cooling water and indoor return air and outdoor fresh air, the cabin space is heated. Simultaneously, the refrigerant piping directly expands into the cold storage compartment for food or aquatic products to maintain an even lower temperature.

[0037] like Figure 12 As shown, the workflow of the air detection and control system is as follows: Step 1: Turn on the air detection and control system; Step 2: The indoor return air vent is opened, and the fan 31 draws in indoor air, which directly exchanges heat with the heat exchanger 151 to become low-temperature air. Step 3: The cold air passes through the air quality detection device 34, which detects the temperature, humidity, PM2.5, carbon dioxide concentration, and formaldehyde concentration of the cold air. Step 4: When any of the detected PM2.5, carbon dioxide, and formaldehyde concentrations in the air exceeds the preset value, the air quality detection device 34 sends a signal to the system. At this time, the valve on the fresh air duct 32 is opened, and fresh air is introduced through the fresh air inlet 35. The fresh air dilutes the concentration of harmful substances in the air, and the mixed air exchanges heat with the heat exchanger 151 to become clean cold air. After the air quality reaches the target, the valve on the fresh air duct 32 is closed.

[0038] like Figure 13 As shown, the workflow of the comfort terminal system is as follows: Step 1: The air detection and control system delivers clean air to the comfort terminal system; Step 2: When in cooling mode, the valve on the cold air duct 23 is opened, and the high-level cold air delivery module is turned on; when in heating mode, the valve on the warm air duct 22 is opened, and the low-level warm air delivery module is turned on.

[0039] Step 3: Clean, cool or warm air is delivered to different depths of the cabin through corresponding, gradually increasing air supply vents to ensure consistent airflow at different depths.

[0040] Step 4: Cold air is sterilized by ultraviolet germicidal lamp 27, and then sent to the top of the cabin through the upward-facing arc-shaped deflector 26. After that, it diffuses downwards at a low speed throughout the entire cabin space, cooling the space and preventing high-speed cold air from directly contacting the human body and causing uncomfortable coldness. Warm air is sterilized by ultraviolet germicidal lamp 27, and then sent to the lower part of the cabin through the downward-facing arc-shaped deflector 26. After that, it rises at a low speed throughout the entire cabin space, heating the space and preventing drowsiness, thus improving the comfort of airflow organization.

[0041] This invention features a structural design that enhances the aesthetics of each system, providing a comfortable working environment for personnel inside the cabin and improving work efficiency and safety. Each subsystem operates independently in parallel, relying on an auxiliary power supply system for electrical energy. The system introduces fresh outdoor air, ensuring clean, comfortable, and safe air within the cabin. The open environment in which the vessel operates facilitates the collection of renewable solar energy, reducing energy consumption.

[0042] This invention has a wide market application and is generally applicable to boats requiring air conditioning. Its comfort and energy-saving features make it suitable for various types of boats, optimizing space structure. The integrated marine energy system combining refrigeration, cooling, and heating is integrated into the hull structure and concealed, enhancing the hull's aesthetics. An automated cabin air detection and control system monitors air quality and introduces fresh air, ensuring air freshness and reducing the concentration of harmful substances. Based on this, the problems of uncomfortable boat air conditioning, high energy consumption, and unsightly appearance are expected to be substantially resolved in the foreseeable future. Since this integrated system can be widely applied to various types of boats, adjustments can be made to parts of the integrated air conditioning system according to the structure of each hull, thus making its widespread adoption and practicality entirely possible. It should be noted that all valves involved can be solenoid valves, facilitating automated system control.
