[0029] During the shipbuilding process, it is necessary to scientifically design and arrange the air conditioning system and ventilation system according to the purpose of the ship, the number of crew members and passengers, and the sailing environment to ensure the good condition of the ship's internal environment. The air conditioning system provides a comfortable indoor environment on the ship, adjusts the indoor temperature and humidity, and enables the crew and passengers to enjoy comfortable climate conditions inside the ship.

[0030] In ordinary air-conditioning systems, fresh air is processed by the central air-conditioning system and then delivered to each room through the air duct. A ceiling-mounted air distribution unit is installed at the end of the air duct, and the air-conditioned air is finally distributed to the room through the ceiling-mounted air distribution unit. The ceiling-mounted air distribution unit is in the shape of a square box with a flat bottom, and is only suitable for conventional flat ceilings without shapes. For public places on passenger and vehicle ships or cruise ships, such as reception halls, entertainment venues, shopping malls and restaurants, for the sake of aesthetic effect, the ceilings of these places are designed with various ups and downs through art seasons. After the ceiling-mounted air distribution unit is installed, there will be a protruding circular chassis, which affects the appearance. The ceiling-mounted air distribution unit is a local air supply, and the air outlet effect can only be felt at the air outlet of the air distribution unit. It is difficult to feel the air supply at a distance from the air outlet. It is more obvious in public places with a large number of people, and the comfort level is poor.

[0031] In order to solve the problem that the ceiling-mounted air distributors cannot be arranged in the art design venue during the design of passenger and vehicle ferries or cruise ships due to the shape of the ceiling, increase the air supply area, save the air supply terminal, and save costs, the present application provides a rain-down air conditioning system.

[0035] The embodiment of the present application discloses a rain-down air conditioning system. Figure 1 , Figure 2 A rain-down air conditioning system includes a ceiling 1 arranged on a steel deck, the ceiling 1 completely covers the bottom wall of the steel deck, and a gap is left between the top wall of the ceiling 1 and the bottom wall of the steel deck to form a gas chamber 11. A vent hole 12 is vertically opened on the ceiling 1, the vent hole 12 completely penetrates the ceiling 1, and the vent hole 12 relatively connects the gas chamber 11 with the interior of the room.

[0036] A gas flow component 2 is disposed inside the gas chamber 11 . The interior of the gas flow component 2 is relatively connected to the interior of the gas chamber 11 , so that the gas flow component 2 can perform gas exchange with the gas inside the gas chamber 11 .

[0037] The gas chamber 11 includes an air supply unit inside, which is used to deliver the supply air in the air conditioner 4 into the gas chamber 11, and then the supply air in the gas chamber 11 enters the room from the air vent 12. A return air unit is provided on one side of the air supply unit, which is used to exchange the return air in the room, so that the return air is transported from the return air unit to the return air end of the air conditioner 4. A transition unit is provided between the air supply unit and the return air unit, which is used to transition between the air supply unit and the return air unit, and is a buffer area between the supply air and the return air.

[0038] In some embodiments, the air supply unit is located near the windows on both sides of the ship, where windows are more likely to conduct heat and the temperature rises faster; in areas where people gather and where people mainly move, people have a higher latent heat and consume more oxygen. The return air area is located in corners, places that are difficult for people to reach, and above the buffet counter.

[0039] Partition walls 3 are fixedly connected to the ceiling 1. The partition walls 3 are respectively located around the air supply part, the return air part and the transition part. The air supply part, the return air part and the transition part are separated by the partition walls 3.

[0040] The gas flow component 2 includes a supply air section located inside the supply air section and a return air section located inside the return air section. The structure of the supply air section is the same as that of the return air section. The difference is that in the supply air section, the gas at the supply air end of the air conditioner 4 enters the supply air section and then enters the room through the supply air section, and in the return air section, the return air in the room passes through the return air section and then is transported back to the return air end of the air conditioner 4.

[0043] The end of the housing 221 away from the main air pipe 21 is fixedly connected with a tail pipe 23, and the interior of the tail pipe 23 is relatively connected to the interior of the housing 221. The end of the tail pipe 23 away from the housing 221 is fixedly connected with a rat-proof net 24, which is a mesh structure.

[0044] The ceiling 1 of the air supply part and the air return part is a perforated ceiling 1, and the aperture and density of the air holes 12 can be calculated. The aperture and hole density of the air holes 12 are calculated according to the required effective ventilation area, and the effective ventilation area = aperture × hole density. The effective ventilation area can be calculated by the following formula:

[0045]
