[0033] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0034] Example 1

[0035] This embodiment provides an air conditioning and ventilation system for chemical tanks inside a ship, such as... Figure 1 As shown, the air conditioning and ventilation system 100 includes: an air conditioning system 110, a refrigeration system 120, a supply and return air duct 130, a sensing device 140, a first coil device 111, a second coil device 121, and a controller 150.

[0036] Air conditioning system 110 is used to regulate the airflow status information of the air conditioning air using a first coil device; the first coil device is installed in the air conditioning system and includes a cooling coil and a heating coil.

[0037] The refrigeration system 120 is used to regulate the airflow status of the air conditioning system using a second coil device when the chemical tanks inside the ship are in operation.

[0038] The supply and return air duct 130 is used to transmit the regulated airflow to the interior of the chemical cabinet, and to transmit the airflow inside the chemical cabinet to the air conditioning system and refrigeration system for circulation.

[0039] Sensor 140 is used to collect environmental parameters inside and outside the chemical cabinet and transmit the environmental parameters to the controller;

[0040] The controller 150 is used to regulate the air conditioning and refrigeration systems according to environmental parameters to ensure that the chemical cabinet is in a safe state.

[0041] The airflow status information includes at least one of the following: temperature, humidity, particle size, salinity, and CO2 concentration.

[0042] In this embodiment, the air conditioning and ventilation system of the ship's chemical tank mainly consists of an air conditioning system, a refrigeration system, supply and return air ducts, sensing devices, and a controller. The supply and return air ducts are electrically connected to the air conditioning system, the refrigeration system, and the controller. The controller can control the air conditioning system, the refrigeration system, the sensing devices, the first coil unit, and the second coil unit. When the chemical tank is in operation or not, the air conditioning system uses the cooling and heating coils of the first coil unit to adjust the airflow status information, such as temperature and humidity information. When the chemical tank is in operation, the second coil unit adjusts the airflow status information. The sensing devices employ a dual closed-loop control method to monitor the internal and external environmental parameters of the chemical tank in real time, thereby enabling the controller to precisely control the operation of the air conditioning system and the refrigeration system to dynamically regulate the chemical tank to maintain a safe operating state.

[0043] In a feasible solution, such as Figure 2 As shown, the sensing device 140 includes a first sensor 141 and a second sensor 142;

[0044] The first sensor 141 is used to collect the first environmental parameters of the chemical room where the chemical cabinet is located, and to transmit the first environmental parameters to the controller.

[0045] The second sensor 142 is used to collect a second environmental parameter inside the chemical cabinet and to transmit the second environmental parameter to the controller.

[0046] In this embodiment, a first sensor is used to collect the first environmental parameters of the external environment of the chemical cabinet in real time, and a second sensor is used to collect the second environmental parameters of the internal environment of the chemical cabinet in real time. The two sensors can accurately obtain the internal and external environmental parameters of the chemical cabinet, which improves the stability and accuracy of the internal and external environmental control of the chemical cabinet and ensures the safety and stability of chemical storage.

[0047] In a feasible solution, if the humidity information of the environmental parameter is greater than the humidity threshold;

[0048] Controller 150 is used to control the increase of the coil opening of the first coil device and the second coil device to reduce humidity information.

[0049] In a feasible solution, if the temperature information of the environmental parameters is greater than the temperature threshold;

[0050] Controller 150 is used to control the increase of the fan in the air conditioning system and refrigeration system to reduce the temperature.

[0051] In a feasible solution, if the CO2 concentration information of the environmental parameter is greater than the concentration threshold;

[0052] Controller 150 is used to control the increase of the fans in the air conditioning system and refrigeration system to reduce CO2 concentration.

[0053] Specifically, based on the comparison results of humidity, temperature and CO2 concentration in the environmental parameters with the corresponding thresholds, the controller adjusts the opening status and fan operation status of the first and second coil devices of the air conditioning system and the refrigeration system respectively, thereby realizing real-time control of the first and second environmental parameters.

[0054] In a feasible solution, such as Figure 2 As shown, the controller includes a first control unit 151 and a second control unit 152;

[0055] The first control unit 151 is used to regulate the air conditioning system according to the difference information between the first environmental parameter and the second environmental parameter so as to keep the chemical room in a safe state.

[0056] The second control unit 152 is used to regulate the refrigeration system based on the difference information between the first environmental parameter and the second environmental parameter, so as to keep the internal environment of the chemical cabinet in a safe state.

[0057] Specifically, by accurately adjusting the air conditioning system and refrigeration system through two control units, the stability and accuracy of the internal and external environmental control of the chemical cabinet are improved, ensuring the safety and stability of chemical storage.

[0058] In this embodiment, an air conditioning and ventilation system for a chemical tank inside a ship is provided. By utilizing an air conditioning system, a refrigeration system, sensing devices, and a controller, the internal and external environmental parameters of the ship's chemical tank can be precisely controlled, reducing condensation, preventing corrosion of the tank body and moisture absorption of chemicals, improving the stability of the chemical tank, and ensuring the safety of chemical storage.

[0059] Example 2

[0060] This embodiment provides a ship, such as Figure 3 As shown, this includes an air conditioning and ventilation system for a shipboard chemical tank, as in Example 1.

[0061] Specifically, by utilizing both the first coil of the air conditioning system and the second coil of the refrigeration system, precise adjustment of the airflow status of the chemical tanks is achieved, whether they are in operation or not. Through precise control of the internal and external environmental parameters of the chemical tanks within the ship, the air conditioning and ventilation system reduces condensation, prevents corrosion and moisture absorption of the chemicals, and improves the stability and accuracy of the control of internal and external environmental parameters, ensuring the safety and stability of chemical storage.
