The control method of the environmental control system is described as follows, which comprises the following steps:
step one, as shown in fig. 3: before loading, the environment control system firstly enters an inerting mode: the controlled valve 108 on the first gas supply line 21, the controlled valve 100 on the second gas supply line 22, the controlled valve 107 on the first exhaust line 31 and the controlled valve 104 on the second exhaust line 32 are open, the valves with arrows in fig. 3, 4 and 5 are shown in an open state, and the remaining valves are in a closed state. The nitrogen generator 20 is operated at a high load, nitrogen provided by the nitrogen generator 20 enters the cargo hold 10 through the first air supply pipeline 21, the high-flow nitrogen introduced through the first air supply pipeline 21 can rapidly perform nitrogen purging and inerting on the cargo hold 10, and the air displaced in the cargo hold 10 is discharged to the external atmosphere through the first exhaust pipeline 31; nitrogen gas supplied from the nitrogen generator 20 is introduced into the insulation cavity 12 through the second gas supply line 22, and the air displaced in the insulation cavity 12 is discharged to the external atmosphere through the second gas discharge line 32. During the inerting process, the pressure in the cargo hold 10 and the insulation cavity 12 can be monitored by means of pressure sensors 41, 42 arranged therein and pressure-controlled, for example, the pressure in the insulation cavity 12 can be controlled by adjusting the opening of a flow valve 110, and the pressure in the cargo hold 10 can be adjusted by means of a controlled valve 108 and the operating load of the nitrogen generator.
And step two, spraying a small amount of liquid cargo into the B-type liquid cargo tank for precooling before loading a large amount of liquid cargo into the B-type liquid cargo tank. During a pre-cooling operation, the environmental control system enters a pre-cooling mode: as shown in fig. 4, the controlled valve 108 on the first gas supply line 21, the controlled valve 100 on the second gas supply line 22, the controlled valve 107 on the first exhaust line 31 and the controlled valve 104 on the second exhaust line 32 start to be in a closed state. As the pre-cooling process progresses, the type B cargo tank is gradually cooled to a low temperature and contracted, the gas phase volume in the cargo tank 10 becomes larger, and the gas pressure decreases. If the pressure difference between the cargo space 10 and the insulation cavity 12 reaches a predetermined value (e.g., 50mmAq), the environmental control unit 40 may control the nitrogen generator 20 to operate at a low load and open the controlled valve 102 of the third gas supply line 23, so that nitrogen is supplied to the cargo space 10 through the third gas supply line 23 to maintain the pressure of the cargo space 10 within a normal range. In this process, the environmental control unit 40 can determine the air tightness of the cargo space 10 according to the flow rate information provided by the flow meter 231 provided on the third air supply pipeline 23, for example, the flow rate is greater than a reasonable value (for example, 50 Nm/Nm)3H), it is determined that there is a leak at the cargo space 10.

After accomplishing above-mentioned process, the utility model discloses can also continue to control the environment that B type cargo tank subsidiary department belonged to, can also include step three promptly: sailing at sea for subsequent loading and loadingDuring unloading, the environmental control system enters a normal mode: as shown in fig. 5, since the insulation cavity 12 is generally provided with a gas pumping detection system, the internal pressure thereof is continuously reduced during the flight. Thus, in normal mode, the environmental control unit 40 opens the controlled valve 100 on the second air supply line 22, unblocks the second air supply line 22, closes the other controlled valves, and disconnects the other air supply and exhaust lines. The nitrogen generator 20 is operated at a low load, and a low flow rate of nitrogen is supplemented into the insulation cavity 12 through the second gas supply line 22, so that the pressure in the insulation cavity 12 is maintained within a set range. In the process, the environmental control unit 40 can determine the air tightness of the insulation cavity 12 according to the flow information provided by the flow meter 221 on the second air supply pipeline 22, for example, the flow value is greater than a reasonable value (e.g., 10 Nm/Nm)3H), it can be determined that there is a leak in the insulating cavity 12.
In addition, the control method may further include a drying step of: before the liquefied gas carrier is docked, the attachment of the B-type cargo tank needs to be ventilated, namely nitrogen in the attachment is replaced by air, and the environment control system enters a drying mode: in the dry mode, the nitrogen generator 20 supplies dry air, no longer nitrogen, and the other lines and valves are in the same state as in the inerting mode. Referring to fig. 3, the controlled valve 108 on the first gas supply line 21, the controlled valve 100 on the second gas supply line 22, the controlled valve 107 on the first exhaust line 31 and the controlled valve 104 on the second exhaust line 32 are open, and the remaining valves are closed. The nitrogen generator 20 is operated at a high load, air supplied from the nitrogen generator 20 is introduced into the cargo hold 10 through the first air supply line 21, and nitrogen displaced in the cargo hold 10 is discharged to the outside atmosphere through the first exhaust line 31; air provided from the nitrogen generator 20 is introduced into the insulation cavity 12 through the second air supply line 22, and the nitrogen displaced in the insulation cavity 12 is discharged to the external atmosphere through the second exhaust line 32.
