[0020] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] like Figures 1-8As shown, this embodiment of the invention provides an air conditioning system applied to a ship, specifically a cruise ship. The air conditioning system is used for temperature regulation or ventilation of the passenger cabin and related functional cabins. The air conditioning system includes a forward air conditioning unit 10 and / or a rear air conditioning unit 20. The forward air conditioning unit 10 includes a forward central air conditioning unit 11, a forward air intake device 21, and a forward exhaust device 31. The air inlet and exhaust outlet of the forward central air conditioning unit 11 are respectively connected to the forward air intake device 21 and the forward exhaust device 31. Both the forward air intake device 21 and the forward exhaust device 31 are located above the forward central air conditioning unit 11 on the deck one level above it. The forward central air conditioning unit 11 is used to ventilate or regulate the temperature of at least some cabins within the ship. The forward air intake device 21 provides air intake to the forward central air conditioning unit 11, and the forward exhaust device 31 discharges exhaust air from the forward central air conditioning unit 11. The aft air conditioning unit 20 includes an aft central air conditioning unit 12, an aft air intake device 22, and a aft exhaust device 32. The air inlet and exhaust outlet of the aft central air conditioning unit 12 are connected to the aft air intake device 22 and the aft exhaust device 32, respectively. The rear air inlet of the aft air intake device 22 is located above the aft central air conditioning unit 12 on the deck above it, and the rear exhaust outlet 321 of the aft exhaust device 32 is located above the aft air inlet on the deck above it. The aft central air conditioning unit 12 is used to ventilate or regulate the temperature of at least some of the cabins of the ship. By setting up forward air conditioning units 10 and / or aft air conditioning units 20, and forward central air conditioning units 11 and / or aft central air conditioning units 12, the ventilation needs of the ship's cabins are met. The forward air intake device 21 and forward air exhaust device 31 are located on the deck above the forward central air conditioning unit 11. The aft air intake of the aft air intake device 22 is located on the deck above the aft central air conditioning unit 12, and the aft air exhaust device 32's aft exhaust outlet 321 is located on the deck above the aft air intake. By setting up forward central air conditioning units 11 and / or aft central air conditioning units 12, the air conditioning layout of each cabin is not too dispersed, and excessive deck space is avoided. The air intake and exhaust of the central air conditioning are directly connected to the upper air intake and exhaust devices through pipelines, reducing the number and length of pipelines, lowering construction costs, and also helping to reduce overall energy consumption during operation.

[0022] Specifically, such as Figures 1-4As shown, both the forward air intake device 21 and the forward exhaust device 31 are located at the bow of the ship, with the forward exhaust device 31 situated in the bow winch area 310. Positioning the forward air intake device 21 and the forward exhaust device 31 at the bow avoids occupying space in the middle of the deck, thus freeing up space in the middle of the cruise ship deck and preventing the forward air intake device 21 and the forward exhaust device 31 from negatively impacting the passenger experience. Positioning the forward exhaust device 31 in the bow winch area 310 ensures that the air exhausted from the forward exhaust port 311 of the forward exhaust device 31 blows into the forward winch area where passengers will not be active, preventing the air exhausted from the forward exhaust device 31 from affecting passengers moving on the deck. Exemplarily, in this embodiment, the forward central air conditioning unit 11 is located on the fourth deck 200, and the forward air intake device 21 and the forward exhaust device 31 are connected to the forward central air conditioning unit 11 via forward air intake duct 41 and forward exhaust duct 42. Furthermore, an air conditioning room for the forward central air conditioning unit 11 can be installed. The forward air intake duct 41 and the forward exhaust duct 42 are connected to the air conditioning room of the forward central air conditioning unit 11 for ventilation. The forward air intake device 21 and the forward exhaust device 31 are installed on the fifth deck 300, that is, above the forward central air conditioning unit 11. The forward air intake duct 41 and the forward exhaust duct 42 pass upward through the fifth deck 300 to connect with the forward air intake device 21 and the forward exhaust device 31, thus shortening the pipeline connection path and saving construction costs. The specific structure of the forward air intake device 21 and the forward exhaust device 31 is existing technology in this field and will not be described in detail here. The ship may, according to its needs and the layout of each compartment, install only the forward air conditioning unit 10 or only the aft air conditioning unit 20, or it may install both the forward air conditioning unit 10 and the aft air conditioning unit 20 simultaneously.

[0023] Furthermore, such as Figures 2-4 As shown, the forward air intake device 21 is located on the port side of the bow, with its forward air intake 211 facing the port side of the ship. This allows it to draw in fresh air from the sea side of the ship and supply it to the forward central air conditioning unit 11, while avoiding the intake of polluted air discharged from the forward exhaust system. Alternatively, the forward air intake device 21 can be located on the starboard side of the bow, with its forward air intake 211 facing the starboard side of the ship. Similarly, this method also ensures the intake of fresh air from the sea side of the ship.

[0024] Specifically, such as Figures 5-8As shown, both the rear air intake device 22 and the rear exhaust device 32 are located at the stern of the ship. The rear exhaust port 321 of the rear air intake device 22 faces the rear of the ship. Along the width direction of the ship, the rear air intake port and the rear exhaust port 321 are spaced apart to prevent the air discharged from the rear exhaust port 321 from being re-inhaled by the rear air intake port. By placing both the rear air intake device 22 and the rear exhaust device 32 at the stern of the ship, space in the middle of the deck is not occupied, thus freeing up space in the middle of the cruise ship deck. Exemplarily, in this embodiment, the rear central air conditioner 12 is located on the third deck 100, the rear air intake port of the rear air intake device 22 is located above the fourth deck 200, and the rear exhaust port 321 of the rear exhaust device 32 is located above the fifth deck 300. Furthermore, an air conditioning room for the rear central air conditioner 12 can be provided, and the rear air intake duct 51 and the rear exhaust duct 61 are connected to the air conditioning room of the rear central air conditioner 12 for ventilation. The rear air intake duct 51 passes upward through the fourth deck 200 and connects to the rear air intake device 22. The rear exhaust duct 61 is connected to the rear exhaust device 32. The exhaust gas passes upward through the fourth deck 200 and the fifth deck 300 and is discharged from the rear exhaust port 321. This results in a shorter pipeline connection path and saves construction costs.

[0025] Furthermore, such as Figures 5-8 As shown, the aft air intake device 22 includes a fresh air distribution compartment 221 and air intake louvers 222. The fresh air distribution compartment 221 is built on the fourth deck 200, and the air intake louvers 222 are located on the forward bulkhead of the fresh air distribution compartment 221 near the stern. The air intake louvers 222 have a rear air inlet, and the rear air intake duct 51 passes upward through the fourth deck 200 and communicates with the interior of the fresh air distribution compartment 221. The arrangement of the fresh air distribution compartment 221 ensures that sufficient fresh air is supplied to the aft air conditioning unit 20.

[0026] Specifically, the rear air conditioning unit 20, in addition to the rear air intake duct 51 and the rear air exhaust duct 61 for supplying and exhausting air to the rear central air conditioning unit 12, also includes a rear supply air duct and a rear return air duct. The rear supply air duct is connected to the interior of the fresh air distribution room 221, and the rear return air duct is connected to the rear exhaust air device 32. The rear supply air duct and the rear return air duct work together to ventilate the compartments that require ventilation. These compartments include, but are not limited to, inverter rooms, electrical rooms, braking resistor rooms, garbage rooms, and laundry rooms. Ventilation is achieved through the rear supply air duct and the rear return air duct, eliminating the need for separate air conditioning ductwork, reducing operating energy consumption, and simultaneously meeting the normal operating conditions of the equipment in the relevant compartments. In addition, both the rear air supply duct and the rear air intake duct 51 draw in fresh air through the fresh air distribution room 221, and both the rear return air duct and the rear exhaust air duct 61 discharge exhaust gas through the rear exhaust air device 32, reducing the number of air intake and exhaust related devices, thereby further reducing the occupation of deck space and reducing construction costs.

[0027] Furthermore, a blower is installed in the rear air supply duct, which blows fresh air from the fresh air distribution room 221 to the compartments requiring ventilation. And / or, a return air fan is installed in the rear return air duct, which blows air from the compartments requiring ventilation to the rear exhaust device 32. Gas circulation is achieved through the blower and / or the return air fan. In this embodiment, a blower is installed in the rear air supply duct and a return air fan is installed in the rear return air duct to achieve higher circulation efficiency and better ventilation effect.

[0028] Specifically, the aft exhaust device 32 is an exhaust duct that extends along the ship's height. The aft exhaust outlet 321 is located at the upper end of the exhaust duct. The lower end of the exhaust duct is located on the same deck as the aft exhaust duct 61 and the aft return air duct, and is connected to them. That is, the aft exhaust outlet 321 at the upper end of the exhaust duct is located above the fifth deck 300. The exhaust duct extends downward through the fifth deck 300 and the fourth deck 200, and connects to the aft exhaust duct 61 and the aft return air duct above the third deck 100.

[0029] Optionally, in this embodiment, multiple rear air supply ducts and multiple rear return air ducts are provided. Specifically, the multiple rear air supply ducts are a first rear air supply duct 52, a second rear air supply duct 53, a third rear air supply duct 54, a fourth rear air supply duct 55, and a fifth rear air supply duct 56. Specifically, the multiple rear return air ducts are a first rear return air duct 62, a second rear return air duct 63, a third rear return air duct 64, a fourth rear return air duct 65, and a fifth rear return air duct 66. The first rear air supply duct 52 and the first rear return air duct 62 are both connected to the converter room and provide ventilation for the converter room; the second rear air supply duct 53 and the second rear return air duct 63 are both connected to the electrical room and provide ventilation for the electrical room; the third rear air supply duct 54 and the third rear return air duct 64 are both connected to the braking resistor room and provide ventilation for the braking resistor room; the fourth rear air supply duct 55 and the fourth rear return air duct 65 are both connected to the garbage room and provide ventilation for the garbage room; the fifth rear air supply duct 56 and the fifth rear return air duct 66 are both connected to the laundry room and provide ventilation for the laundry room.

[0030] Optionally, the rear air conditioning unit 20 also includes a rear ventilation duct 57, which is connected to the fresh air distribution room 221. The rear ventilation duct 57 is used to connect with the ship's indoor public areas to facilitate the balance of internal and external air pressure.

[0031] It should be noted that in other embodiments, the positions of the front air conditioning unit 10 and the rear air conditioning unit 20 in this embodiment can be interchanged according to the different layout of the ship. That is, the front air conditioning unit 10 is placed at the stern of the ship and the rear air conditioning unit 20 is placed at the bow of the ship. The relevant functions can be achieved in the same way, which will not be described in detail here.

[0032] This invention provides a ship including the air conditioning system described in this embodiment. By implementing the air conditioning system described in this embodiment, the ship occupies less deck space, has lower construction costs, and reduces overall operating costs.
