Description

Technical Field

[0001] This utility model relates to the field of marine ventilation technology, and in particular to an air conditioning ventilation system for marine energy storage battery rooms. Background Technology

[0002] Energy storage batteries can effectively reduce carbon emissions from ship operations and reduce the use of generators. They have advantages such as being environmentally friendly and low-noise, and are increasingly favored by ship owners. However, the application of energy storage batteries in ships has also brought new challenges to ship design.

[0003] The design of the air conditioning and ventilation system for shipboard energy storage battery rooms requires maintaining a relatively low room temperature (16-20 degrees Celsius) due to the characteristics of the energy storage batteries. Maintaining this temperature consumes a significant amount of energy, and reducing the fresh air volume is key to lowering energy consumption. However, the design of the system must also consider the hazards posed by a leak of hazardous gases from the battery packs. To quickly remove the leaked gases through ventilation, an increased fresh air volume is necessary. Therefore, the design of the air conditioning and ventilation system for shipboard energy storage battery rooms faces a trade-off between energy consumption and safety. Furthermore, it must consider the positive and negative pressure issues within the room to prevent the spread of hazardous gases on the ship, as well as the operation of the air conditioning and ventilation system in the event of a fire. The air conditioning and ventilation system is crucial for ensuring the normal and safe operation of energy storage batteries on ships, and it is also a challenging design area. Moreover, the application of energy storage batteries on ships is still in its early stages, lacking mature design standards and easily overlooked. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an air conditioning and ventilation system for ship energy storage battery rooms, which can conveniently switch modes according to different scenarios to ensure the normal and safe operation of energy storage batteries on ships.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An air conditioning and ventilation system for a ship's energy storage battery compartment includes a fresh air assembly, a temperature control assembly, an air supply assembly, and a data acquisition assembly located within the battery compartment, and a control box located outside the battery compartment. The air inlet of the fresh air assembly is connected to the outside, and the air outlet of the fresh air assembly is connected to the air inlet of the temperature control assembly. The air inlet of the air supply assembly is connected to the battery compartment, and the air outlet of the air supply assembly is connected to the outside. The control box is electrically connected to the fresh air assembly, the temperature control assembly, and the air supply assembly via the data acquisition assembly. The temperature control assembly includes two independent air conditioners, and the air supply ducts of the two independent air conditioners form a ring-shaped air supply duct around the energy storage battery module. Multiple air outlets are spaced apart on the ring-shaped air supply duct, and the two independent air conditioners are electrically connected to the control box.

[0007] Furthermore, a backflow preventer is installed on the inlet side of the air supply duct of both independent air conditioners.

[0008] Furthermore, the data acquisition component includes a temperature sensor, a hazardous gas sensor, a fire sensor, and a differential pressure sensor, and the two independent air conditioners are electrically connected to the control box through the temperature sensor, the hazardous gas sensor, and the fire sensor.

[0009] Furthermore, the fresh air assembly includes a blower and a fresh air duct. The air inlet of the blower is connected to the outside, the air outlet of the blower is connected to the inlet of the fresh air duct, and the outlet of the fresh air duct is connected to an independent air conditioning inlet. The blower is frequency-controlled and is electrically connected to the control box through a differential pressure sensor, a hazardous gas sensor, and a fire sensor.

[0010] Furthermore, a remote-controlled air damper is provided outside the air inlet of the blower, and the remote-controlled air damper is electrically connected to the control box through a fire sensor.

[0011] Furthermore, the air supply assembly includes an exhaust fan, the exhaust fan inlet is connected to the interior of the energy storage battery compartment, the exhaust fan outlet is connected to the outside, the exhaust fan is frequency-controlled, and the exhaust fan is electrically connected to the control box through a differential pressure sensor, a hazardous gas sensor, and a fire sensor.

[0012] Furthermore, a remote-controlled air damper is provided outside the air inlet of the exhaust fan, and the remote-controlled air damper is electrically connected to the control box through a fire sensor.

[0013] Furthermore, the exhaust fan, blower, temperature sensor, hazardous gas sensor, fire sensor, and differential pressure sensor are all explosion-proof, while the independent air conditioner is non-explosion-proof.

[0014] Compared with existing technologies, the ventilation system for chemical tanker cargo holds of this utility model has the following advantages:

[0015] 1. Under normal operation, the air supply fan runs at low speed, and the fresh air brings less air conditioning load to the room, which reduces the cooling capacity and size of the air conditioner, making the air conditioner smaller and easier to install, and the purchase cost lower;

[0016] 2. In the event of a hazardous gas leak, the exhaust fan can automatically switch to high-speed operation, which can quickly dilute the leaked hazardous gas and ensure the safety of the room;

[0017] 3. Under normal circumstances, the ventilation system maintains positive pressure in the room to prevent dangerous gases from leaking from the energy storage battery modules. When dangerous gases are detected in the room, the ventilation system creates negative pressure to prevent the dangerous gases from spreading to other areas of the ship. The ventilation system allows for positive and negative pressure switching in the room, ensuring the safety of the ship.

[0018] 4. It is equipped with two independent air conditioners, both of which are connected to the air conditioning duct loop, which gives the room's air conditioning cooling system a certain degree of redundancy and reduces costs. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0022] like Figure 1 As shown, an air conditioning and ventilation system for a ship's energy storage battery compartment includes a fresh air assembly, a temperature control assembly, an air supply assembly, and a data acquisition assembly located within the energy storage battery compartment 13, and a control box 3 located outside the energy storage battery compartment 13. The air inlet of the fresh air assembly is connected to the outside, and the air outlet of the fresh air assembly is connected to the air inlet of the temperature control assembly. The air inlet of the air supply assembly is connected to the energy storage battery compartment 13, and the air outlet of the air supply assembly is connected to the outside. The control box 3 is electrically connected to the fresh air assembly, the temperature control assembly, and the air supply assembly through the data acquisition assembly. The temperature control assembly includes two independent air conditioners 1, and the air supply ducts of the two independent air conditioners 1 form a ring-shaped air conditioning air supply duct 2 around the energy storage battery module 14. Multiple air supply outlets 21 are spaced apart on the ring-shaped air conditioning air supply duct 2, and the two independent air conditioners 1 are electrically connected to the control box 3.

[0023] Understandably, firstly, this energy storage battery room 13 is equipped with two independent air conditioners 1, which are not explosion-proof, to ensure the room temperature (16~20 degrees Celsius). The independent air conditioner 1 has a cooling cycle, which can cool the room and remove the heat emitted by the energy storage battery; the cooling capacity of each independent air conditioner 1 is 50% of the room load; secondly, the air supply ducts of the two independent air conditioners 1 form a loop, which delivers air evenly to the room through the air supply outlet 21.

[0024] In some embodiments, a backflow preventer 4 is provided on the inlet side of the air supply duct of each of the two independent air conditioners 1. With this configuration, the air outlet of the independent air conditioner 1 is equipped with a backflow preventer 4, so that when one independent air conditioner 1 is not working, the other independent air conditioner 1 can still supply air to the entire air duct loop.

[0025] In this embodiment, the data acquisition component includes a temperature sensor 5, a hazardous gas sensor 6, a fire sensor 7, and a differential pressure sensor 8, all of which are explosion-proof. The two independent air conditioners 1 are electrically connected to the control box 3 via the temperature sensor 5, hazardous gas sensor 6, and fire sensor 7.

[0026] In this embodiment, the fresh air assembly includes a blower 9 and a fresh air duct 10. The air inlet of the blower 9 is connected to the outside, the air outlet of the blower 9 is connected to the inlet of the fresh air duct 10, and the outlet of the fresh air duct 10 is connected to the air inlet of an independent air conditioner 1. The blower 9 is frequency-controlled and is electrically connected to the control box 3 through a differential pressure sensor 8, a hazardous gas sensor 6, and a fire sensor 7.

[0027] The air supply assembly includes an exhaust fan 11. The air inlet of the exhaust fan 11 is connected to the interior of the energy storage battery compartment 13, and the air outlet of the exhaust fan 11 is connected to the outside. The exhaust fan 11 is frequency-controlled and is electrically connected to the control box 3 through a differential pressure sensor 8, a hazardous gas sensor 6, and a fire sensor 7.

[0028] Furthermore, a remote-controlled air damper 12 is provided outside the air inlet of the supply fan 9, and the remote-controlled air damper 12 is electrically connected to the control box 3 via a fire sensor 7. A remote-controlled air damper 12 is also provided outside the air inlet of the exhaust fan 11, and the remote-controlled air damper 12 is electrically connected to the control box 3 via a fire sensor 7. This arrangement, with the remote-controlled air dampers 12 positioned at the air inlet and outlet of the room, effectively cuts off the connection between the room and the outside atmosphere.

[0029] Understandably, the control box 3 is located outside the energy storage battery room 13 to control the supply fan 9, exhaust fan 11, remote control air damper 12 and independent air conditioner 1. The differential pressure sensor 8 monitors the air pressure in the room and can change the motor frequency of the exhaust fan 11 and supply fan 9 based on this signal.

[0030] The interior of the energy storage battery module 14 is a dangerous area. Under normal circumstances, the room is a safe area. At this time, the air supply fan 9 runs at low speed, supplying fresh air to the room at 1 to 2 times per hour. The exhaust fan 11 is frequency-controlled according to the signal from the differential pressure sensor 8 to keep the room under positive pressure.

[0031] When the hazardous gas sensor 6 alarms, it indicates that the hazardous gas in the energy storage battery module 14 has leaked. At this time, the room becomes a dangerous area. The power supply to the independent air conditioner 1 needs to be cut off, and the exhaust fan 11 turns on high speed to make the room have 6 air exchanges per hour. The supply fan 9 is controlled by frequency conversion according to the signal of the differential pressure sensor 8 to keep the room under negative pressure and prevent the hazardous gas from spreading further to other areas on the ship.

[0032] When the fire sensor 7 alarms, the power supply to the air supply fan 9, exhaust fan 11 and independent air conditioner 1 is cut off, the remote control damper 12 is turned off, and the room's fire extinguishing system is activated.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
