[0025] A liquid supply pipeline water pressure sensor 1204 and a liquid supply pipeline outlet temperature sensor 1206 are arranged in series on the liquid supply main pipe out of the pump; a buffer mixing tank 1217 is arranged on the liquid supply main pipe in the pump; a second pressure sensor 1205 and a return liquid temperature sensor 1207 are installed in series on the return liquid main pipe;

[0026] On the liquid return main pipe inside the glycol cooling module 102, the bypass pipe is also connected after passing through the pressure sensor 1205 and the liquid return temperature sensor 1207, wherein the inlet of the bypass pipe is connected to the liquid return main pipe, the outlet of the bypass pipe is connected to the liquid supply main pipe merged into the pump, and the inlet of the bypass pipe is also connected to the inlet pipeline of the buffer mixing tank 1217; the bypass pipe is connected to the electric bypass valve 1203; the electric bypass valve 1203, the liquid supply pipeline outlet temperature sensor 1206, the second pressure sensor 1205 and the liquid return temperature sensor 1207 are connected to the environmental control module control box 2 through a signal line;

[0027] The glycol cooling module 102 further includes a flow sensor 1208, wherein:

[0028] The flow sensor 1208 is arranged on the liquid return main pipe, the flow sensor 1208 is connected in series with the first evaporator 1106 and the first ethylene glycol liquid return filter 1209, the flow sensor 1208 is connected in series with the second evaporator 1107 and the second ethylene glycol liquid return filter 1210; the flow sensor 1208 is connected to the environmental control module control box 2 through a signal line;

[0029] The seawater source compression condensation module 101 further includes:

[0030] A first condensing pressure regulating valve 1112 and a second condensing pressure regulating valve 1113 are arranged in parallel on the seawater inlet pipeline;

[0031] The seawater inlet pipeline is respectively connected to a first seawater temperature sensor 1114, a first seawater pressure sensor 1116 and a first antifreeze relief valve 1117;

[0032] The seawater outlet pipeline is respectively connected to a second seawater temperature sensor 1115 and a second antifreeze relief valve 1118;

[0033] The first seawater temperature sensor 1114, the first seawater pressure sensor 1116 and the second seawater temperature sensor 1115 are all connected to the environment control module control box 2 via signal lines;

[0034] On the pipeline before the first fluorine inlet of the first refrigeration compressor 1101 connected to the condenser 1103, a parallel double hot gas bypass pipeline is provided, and a first hot gas bypass valve group 1108 and a first hot gas bypass valve group 1109 are connected in parallel on each bypass pipeline;

[0035] A parallel double hot gas bypass pipeline is arranged on the pipeline before the second fluorine inlet of the second refrigeration compressor 1102 connected to the condenser 1103, and a second hot gas bypass valve group 1110 and a second hot gas bypass valve group 1111 are connected in parallel to each bypass pipeline.

[0036] Further, in the above system, the first thermal expansion valve 1104 is used to control the evaporation temperature of the first evaporator 1106 to fluctuate within a preset effective range; the second thermal expansion valve 1105 is used to control the evaporation temperature in the second evaporator 1107 to fluctuate within a preset effective range;

[0037] The first condensing pressure regulating valve 1112 and the second condensing pressure regulating valve 1113 control the flow rate of cooling seawater by changing the opening degree of the first condensing pressure regulating valve 1112 and the second condensing pressure regulating valve 1113 by directly sensing the condensing pressure of the fluorine refrigerant in the shell and tube condenser 1103. When the condensing pressure in the condenser 1103 increases, the flow area of ​​the valve core is automatically opened to allow more cooling seawater to enter the condenser 1103, thereby accelerating the condensation speed of the fluorine refrigerant and reducing the pressure value in the condenser 1103 to return to the set value. On the contrary, when the condensing pressure decreases, the first condensing pressure regulating valve 1112 and the second condensing pressure regulating valve 1113 are automatically closed to reduce the amount of cooling seawater entering the condenser 1103, thereby increasing the pressure value in the condenser 1103 and returning to the set value.

[0038] Further, in the above system, the environment control module control box 2 is used for initially starting the equipment, according to the accumulated running time of each of the first refrigeration compressor 1101 and the second refrigeration compressor 1102, to select the one with the shorter accumulated running time of the first refrigeration compressor 1101 and the second refrigeration compressor 1102 to start first;

[0039] The environmental control module control box 2 is used to automatically calculate the total load heat in the environmental control module control box 2 according to the collected temperatures of the liquid supply pipeline outlet temperature sensor 1206 and the return liquid temperature sensor 1207 in the ethylene glycol cooling module 102, and the total liquid supply flow collected by the return liquid flow sensor 1208. When the total load heat>half of the cooling capacity, the other refrigeration compressor that has not been turned on among the first refrigeration compressor 1101 and the second refrigeration compressor 1102 is turned on; when the load heat is detected to be ≤half of the cooling capacity for more than a preset time during operation, the operation of one of the refrigeration compressors is stopped;

[0040] The environment control module control box 2 is used to process according to the following logic when the seawater source compression and condensation module 101 fails:

[0041] When only one of the first refrigeration compressor 1101 and the second refrigeration compressor 1102 is in operation, the environment control module control box 2 automatically switches to the other refrigeration compressor when it detects that the running refrigeration compressor is overloaded, over-pressured or has other faults;

[0042] When the first refrigeration compressor 1101 and the second refrigeration compressor 1102 are running at the same time, when the environmental control module control box 2 detects an overcurrent, overpressure or fluorine high pressure alarm fault in the first refrigeration compressor 1101 or the second refrigeration compressor 1102, the environmental module control box 2 stops the corresponding faulty refrigeration compressor and sends an alarm signal to the host computer. During this period, the ethylene glycol cooling module 102 does not stop working.

[0043] Further, in the above system, the environment control module control box 2 is used to determine whether to give priority to starting the first ethylene glycol liquid supply circulation pump 1201 or the second ethylene glycol liquid supply circulation pump 1202 with a shorter cumulative operation time, based on the respective cumulative use time of the first ethylene glycol liquid supply circulation pump 1201 and the second ethylene glycol liquid supply circulation pump 1202 each time the machine is turned on;

[0044] After the equipment is powered on, the flow rate and pressure will not be detected within 10 seconds after the first ethylene glycol liquid supply circulation pump 1201 or the second ethylene glycol liquid supply circulation pump 1202 starts running. After 10 seconds, the flow rate alarm and pressure alarm will be detected. The first ethylene glycol liquid supply circulation pump 1201 or the second ethylene glycol liquid supply circulation pump 1202 will not stop running, and the alarm signal will be sent to the host computer;

[0045] When the system is running, when the environment control module control box 2 detects that the started first ethylene glycol liquid supply circulation pump 1201 or the second ethylene glycol liquid supply circulation pump 1202 sends an overload alarm signal, it automatically switches to start the other stopped second ethylene glycol liquid supply circulation pump 1202 or the first ethylene glycol liquid supply circulation pump 1201;

[0046] During the operation of the first ethylene glycol liquid supply circulation pump 1201 or the second ethylene glycol liquid supply circulation pump 1202, only the stop command issued by the host computer is accepted, and the seawater source marine integrated server liquid cooling device 1 does not decide to stop the ethylene glycol liquid supply circulation pump 1201 or 1202 by itself.

[0047] Furthermore, in the above system, the control box 2 of the environmental control module is used to collect the temperature values ​​of the outlet temperature sensor 1206 and the return liquid temperature sensor 1207 of the liquid supply pipeline in real time, as well as the total liquid supply flow of the electromagnetic flow sensor 1208 on the return liquid main pipe, and automatically calculate the total load heat. When the load heat is greater than the first preset threshold, such as the load heat>10kW, the other fluorine refrigeration system of the seawater source compression condensation module 101 is turned on; during operation, when it is detected that the load heat is less than or equal to the first preset threshold, the load heat is ≤10kW for more than 3 minutes, the second fluorine refrigeration system of the seawater source compression condensation module 101 can be stopped to ensure that the overall refrigeration capacity of the device matches the load heat;

[0048] The environmental control module control box 2 is used to open the parallel double hot gas bypass pipelines and the first hot gas bypass valve group 1108 and the first hot gas bypass valve group 1109 on the Freon refrigerant pipeline at the outlet of the running first vertical scroll compressor 1101, or open the parallel double hot gas bypass pipelines and the first hot gas bypass valve group 1110 and the second hot gas bypass valve group 1111 on the Freon refrigerant pipeline at the outlet of the running second compressor 1102 when the supply liquid temperature is still higher than the set temperature; when the supply liquid temperature is still higher than the set temperature, the first hot gas bypass valve group or the second hot gas bypass valve group is also opened to allow part of the fluorine refrigerant to bypass the plate evaporator and directly enter the inlet of the refrigeration compressor, thereby reducing the heat exchange amount with the ethylene glycol supply liquid, thereby increasing the supply liquid temperature;

[0049] The environmental control module control box 2 is used to gradually open the electric bypass valve 1203 between the supply and return liquid main pipes when the liquid supply temperature is still higher than the set temperature, bypass and reflux a small amount of high-temperature ethylene glycol return liquid to mix with the low-temperature ethylene glycol supply liquid, and appropriately increase the liquid delivery temperature. When the temperature of the ethylene glycol solution monitored by the supply pipeline outlet temperature sensor 1206 is still lower than the data server required temperature, the electric bypass valve 1203 can be opened step by step until the difference between the ethylene glycol supply temperature and the set temperature does not exceed ±2°C.

[0050] Furthermore, in the above system, the glycol cooling module 102 further includes: a first glycol liquid return filter 1209 and a second glycol liquid return filter 1210, wherein:

[0051] The first ethylene glycol liquid return filter 1209 and the second ethylene glycol liquid return filter 1210 are arranged in parallel on the liquid return main pipe after passing through the bypass pipe. The inlet of the first ethylene glycol liquid return filter 1209 is connected to the first electric butterfly valve 1211, and the outlet of the first ethylene glycol liquid return filter 1209 is connected to the second electric butterfly valve 1212; the inlet of the first ethylene glycol liquid return filter 1210 is connected to the third electric butterfly valve 1213, and the outlet of the first ethylene glycol liquid return filter 1209 is connected to the fourth electric butterfly valve 1214;

[0052] A third pressure sensor 1215 is connected to the combined inlet pump liquid supply main pipe of the first ethylene glycol liquid return filter 1209 and the second ethylene glycol liquid return filter 1210, and a fourth pressure sensor 1216 is arranged on the combined outlet pump liquid supply main pipe of the first ethylene glycol liquid return filter 1209 and the second ethylene glycol liquid return filter 1210. The first electric butterfly valve 1211, the second electric butterfly valve 1212, the third electric butterfly valve 1213, the fourth electric butterfly valve 1214, the third pressure sensor 1215 and the fourth pressure sensor 1216 are all connected to the environmental control module control box 2 through signal lines.

[0053] Further, in the above system, the environment control module control box 2 monitors the pressure at both ends of the first ethylene glycol liquid return filter 1209 and the second ethylene glycol liquid return filter 1210 by setting the third pressure sensor 1215 and the fourth pressure sensor 1216 at the inlet and outlet ends of the first ethylene glycol liquid return filter 1209 and the second ethylene glycol liquid return filter 1210, and obtains the pressure drop value of the first ethylene glycol liquid return filter 1209 and the second ethylene glycol liquid return filter 1210 by subtracting the values ​​at both ends, and compares it with the recorded initial pressure drop value. When the pressure drop exceeds the allowable threshold, an alarm is issued to display that the first ethylene glycol liquid return filter 1209 and the second ethylene glycol liquid return filter 1210 are dirty and blocked, and corresponding measures are automatically initiated to deal with the fault. The specific control mode is:

[0054] When the seawater source marine integrated server liquid cooling and cooling device 1 is not started, in the initial detection state, the seawater source marine integrated server liquid cooling and cooling device 1 is stopped from starting and running, an audible and visual alarm is issued, and the cause of the fault is marked on the display screen of the environment control module control box 2;

[0055] When the seawater source marine integrated server liquid cooling device 1 is started, during operation, if the first ethylene glycol liquid return filter 1209 and the second ethylene glycol liquid return filter 1210 are detected to be dirty or blocked, a delay of 2 minutes is given, and an audible and visual alarm is issued to indicate the dirty or blocked fault of the first ethylene glycol liquid return filter 1209 and the second ethylene glycol liquid return filter 1210, and information is reported to the upper computer at the same time, and the server operation status is communicated with the upper computer. If the data server is in operation, the first ethylene glycol liquid return filter 1209 and the second ethylene glycol liquid return filter 1210 are opened. All four electric butterfly valves, namely the first electric butterfly valve 1211, the second electric butterfly valve 1212, the third electric butterfly valve 1213 and the fourth electric butterfly valve 1214, on the inlet and outlet of the return liquid filter 1210, and the ethylene glycol cooling module 102 enter the over-current operation state to ensure that the flow meets the server operation requirements; at the same time, the fault display on the screen 204 of the environmental control module control box 2 remains until the host computer issues a shutdown command, and then the seawater source marine integrated server liquid cooling device 1 can be stopped and the corresponding components can be repaired.

[0056] Furthermore, in the above system, the ethylene glycol cooling module 102 further includes: a constant pressure liquid replenishment and exhaust component, wherein the constant pressure liquid replenishment and exhaust component includes: a liquid adding tank 1218, a liquid level sensor 1219 on the liquid adding tank, a closed expansion tank 1220, a liquid replenishment pump 1221, a water replenishment filter 1222, an automatic exhaust valve 1223, a liquid supply pipeline system pressure sensor 1224, a first automatic water replenishment valve 1225, a second automatic water replenishment valve 1226 and a liquid adding pipeline,

The specific control logic is as follows:

[0086] Step S1, after the environment control module control box 2 detects that the seawater source marine integrated server liquid cooling refrigeration device 1 cannot operate normally or cannot be operated in an emergency override mode, it issues an on-site sound and light alarm message, and the screen of the environment control module control box 2 displays the specific faulty device, and at the same time, it alerts the upper computer;

[0088] Step S3, the environment control module control box 2 monitors the operating status of the seawater source air conditioner 4 and the duct fan 5 in the cabin of the ship data center and the air temperature in the cabin in real time. When any of the seawater source air conditioner 4 and the duct fan 5 in the cabin of the ship data center fails to operate, or the temperature in the cabin of the data center exceeds the threshold requirement, an on-site sound and light alarm message is issued, the specific faulty device is displayed on the screen, and an alarm is sent to the upper computer at the same time;

[0090] Step S5, the environment control module control box 2 is used to automatically cut off the liquid cooling conversion electric valve 10 when the seawater source marine integrated server liquid cooling supply device 1 fails and can run continuously for a specified time. After the system sound and light alarm stops, a normal operation signal is sent to the upper computer. The upper computer controls to close the sound and light alarm information turned on in step S3, closes the seawater source air conditioner 4 and the duct fan 5 turned on in step S2, and closes the standby cold source and alarm turned on in step S4.

[0091] The seawater source marine integrated server liquid cooling device 1 is a specially developed compact marine liquid cooling device with high reliability, unattended operation, and automatic and rapid dynamic response to major faults. It provides cooling ethylene glycol coolant and serves data servers. Figure 2 As shown, the seawater source marine integrated server liquid cooling device 1 is mainly composed of a compression condensation module 101 and an ethylene glycol cooling module 102. See Example 2 for a detailed description.

[0092] The terminal control unit 3 is mainly composed of an inlet pressure sensor 304, an outlet pressure sensor 303, an outlet temperature sensor 302, a hydraulic balance valve 301, etc. The inlet pressure sensor 304, the outlet pressure sensor 303 and the outlet temperature sensor 302 transmit the monitored data to the environment control module control box 2 in real time, so as to realize the real-time monitoring of the inlet and outlet pressures and outlet temperatures of the liquid-cooled cold plates in each data server 901, 902. At the same time, the hydraulic balance valve 301 arranged at the return water outlet adjusts and locks the liquid supply of the liquid-cooled cold plate in each data server to ensure that the flow rate of ethylene glycol refrigerant supplied to the liquid-cooled cold plate in each data server meets the requirements.

[0093] The seawater source air conditioner 4 in the cabin of the ship data center is mainly used for adjusting the temperature and humidity of the air environment in the cabin of the ship data center, and providing a thermal environment that meets the working requirements for the equipment in the cabin. The seawater source air conditioner 4 in the cabin of the ship data center is mainly composed of two compressors, a shell and tube condenser, an evaporator, an electric heater, two low-noise centrifugal fans, two thermal expansion valves, several solenoid valves, a drying filter, and an electric control box. This equipment uses seawater as the condensing medium, selects a liquid-gas exchange evaporator with a large air flow, and controls the evaporation temperature through an electric thermal expansion valve to achieve a special air conditioner for the cabin of the ship data center with a high sensible heat ratio, large air volume, and small enthalpy difference. The equipment is equipped with two sets of condensing units to improve the reliability of the entire unit. At the same time, when the seawater source marine integrated server liquid cooling supply device 1 fails and shuts down, it can be started as an emergency air conditioning cooling facility.

[0094] The duct fan 5, electric fire damper 6 and air filter 7 in the cabin of the ship data center constitute the environmental ventilation facilities of the cabin of the ship data center, which automatically realize the working condition that the duct fan 5 is powered on and the electric fire damper 6 is opened every 4 hours to start ventilation for 15 minutes, and the toxic and harmful gases that may be generated in the cabin of the ship data center are filtered and purified by the air filter 7 and then discharged to maintain the cleanliness of the air in the cabin of the ship data center.

[0095] Three air environment sensors 8 can be installed in typical monitored locations of the ship data center cabin, which can comprehensively monitor the air temperature, humidity and cleanliness in the ship data center cabin, and send real-time monitoring data to processing, display and recording.

[0096] The ship data center cabin is equipped with a leakage detection rope 9 around the equipment that is prone to leakage. When the liquid supply pipeline or the internal pipeline accessories of the equipment leak liquid and flow to the deck of the ship data center cabin, the leakage detection rope 9 detects the leakage of liquid and sends a leakage signal to the environment control module control box 2. The environment control module control box 2 sends out an audible and visual alarm, displays fault information on the screen, and sends the corresponding fault signal to the host computer.

[0097] The ship data center cabin air environment sensor 8, water leakage detection rope 9, water inlet pressure sensor 304, water outlet pressure sensor 303 and water outlet temperature sensor 302 in the terminal control unit 3 can be used to fully monitor the parameters related to the ship data center cabin and environmental control. When a fault is detected, an automatic sound and light alarm will be given, and the fault type and disposal measures will be highlighted on the display screen of the environmental control module control box 2, and the upper computer will be reported in time, realizing the functions of unmanned operation and automatic and rapid response to handle key faults.

[0098] Example 2

[0099] like Figure 2 , 5 As shown in , 6 and 7, based on Example 1, a seawater source marine integrated server liquid cooling device 1 comprises:

[0100] The seawater source marine integrated server liquid cooling device 1 is a set of seawater with a rated cooling capacity of more than 20KW as a condensing cold source, which can provide a stable low-temperature ethylene glycol coolant to the data server for cooling and heat exchange. Figure 2 As shown, the seawater source marine integrated server liquid cooling device 1 is mainly composed of two main modules, including: a seawater source compression condensation module 101, and an ethylene glycol cooling module 102. The environmental control module control box 2 described in Example 1 is respectively connected to the seawater source compression condensation module 101 and the ethylene glycol cooling module 102. The three modules of the seawater source compression condensation module 101, the ethylene glycol cooling module 102 and the environmental control module control box 2 can be integrated in a box frame 103.

[0101] like Figure 4 As shown, the frame box 103 is a cubic cabinet structure, and the overall frame is made of 316L stainless steel. The front of the box is divided into four parts, the upper left part is set as the environmental control module control box 2, and the other three parts are detachable panels 1301. At the same time, detachable panels are also set on the left, right, top and rear of the box, which is convenient for maintenance and replacement of the entire set of unit components, pipelines, etc. The box is divided into two layers. The upper layer is mainly composed of compression condensation components and constant pressure water replenishment components, and the lower layer is arranged with ethylene glycol cooling components and shell and tube condenser 1103, one of the main components of the compression condensation module 101 of the seawater source.

[0102] The integrated server liquid cooling device 1 comprises: a seawater source compression condensation module 101 and an ethylene glycol cooling module 102; the integrated server liquid cooling device 1 and an environment control module control box 2 are integrated and configured in a box frame 103; the seawater source compression condensation module 101 and the ethylene glycol cooling module 102 are connected through a Freon refrigerant pipeline;

[0103] The frame box 103 is a two-layer box structure, the environment control module control box 2, the seawater source compression condensation module 101 and the ethylene glycol cooling module 102 are arranged in the frame box 103, and the front, back and both sides of the frame box 103 are equipped with removable panels 1301;

[0104] like Figure 2As shown, the seawater source compression condensation module 101 adopts a dual-cycle fluorine refrigeration system design, including two sets of fluorine refrigeration systems, and the two sets of fluorine refrigeration systems share a condenser 1103, wherein the first set of fluorine refrigeration system includes: a first refrigeration compressor 1101, a condenser 1103, a first thermal expansion valve 1104 and a first evaporator 1106, etc., which are connected to form a closed fluorine refrigeration system through copper pipes; the second set of fluorine refrigeration system includes: a second refrigeration compressor 1102, a condenser 1103, a second thermal expansion valve 1105 and a second evaporator 1107, etc., which are connected to form a closed fluorine refrigeration system through copper pipes; wherein the first and second refrigeration compressors 1 101 and 1102 compress the refrigerant into high-temperature and high-pressure gas, which exchanges heat with external seawater in the condenser 1103 and becomes high-pressure liquid refrigerant. After being throttled by the first and second thermal expansion valves 1104 and 1105, it becomes a low-pressure and low-temperature gas-liquid two-phase mixture, and enters the first and second evaporators 1106 and 1107 respectively to exchange heat with the ethylene glycol coolant. The low-temperature and low-pressure refrigerant vaporizes and absorbs heat to become a low-pressure gas refrigerant, thereby reducing the temperature of the ethylene glycol coolant on the other side of the first and second evaporators 1106 and 1107; the generated low-pressure gas is sucked into the first and second compressors 1101 and 1102 again, and the refrigeration cycle is repeated over and over again. The seawater source compression and condensing module 101 is designed to reduce the size of the seawater source marine integrated server liquid cooling supply device 1. The first and second refrigeration compressors 1101 and 1102 are both scroll vertical compressors, which are arranged side by side in the upper left corner of the box frame 103. The first refrigeration compressor 1101 is connected to the first fluorine inlet of the condenser 1103 through the refrigerant pipeline, and the second refrigeration compressor 1102 is connected to the second fluorine inlet of the condenser 1103. The condenser 1103 can be a shell and tube condenser, for example. At the same time, parallel double hot gas bypass pipelines are respectively arranged, and a pair of hot gas bypass valve groups are respectively arranged on each bypass pipeline, which are the first and second hot gas bypass valve groups 1108 and 1109, and the second and second hot gas bypass valve groups 1110 and 1111. Condenser 1103 has a large heat exchange capacity and is also the largest component of the device. In order to reduce the overall size of condenser 1103 and have a relatively complete anti-seawater corrosion capability, the design selected a shell and tube condenser 1103 with a double fluorine-seawater heat exchange structure, which not only meets the needs of two sets of relatively independent fluorine refrigerant pipelines, but also reduces the number of condensers 1103 and reduces the overall size of condenser 1103. At the same time, the internal seawater pipeline of the double fluorine-seawater shell and tube condenser 1103 adopts high-quality B30 copper-nickel tubes, and the end cover adopts cast aluminum bronze, which has good corrosion resistance and meets the corrosion resistance requirements of seawater cooling source. Considering that the size and weight of the shell and tube condenser account for a large proportion, in order to balance the overall weight balance and center of gravity position of the device, it is arranged on the lower right side of the box.In order to meet the refrigeration requirements under different seawater temperature conditions in global shipping areas, the rated design temperature of the seawater inlet of the condenser 1103 is selected to be 36°C, and a first condensing pressure regulating valve 1112 and a second condensing pressure regulating valve 1113 are arranged in parallel on the seawater pipeline. The inlet and outlet seawater pipelines are respectively provided with a first and a second seawater temperature sensor 1114 and 1115 resistant to seawater corrosion, and a seawater pressure sensor 1116 is arranged at the seawater inlet, a first antifreeze relief valve 1117 is arranged on the inlet seawater pipeline, and a second antifreeze relief valve 1118 is arranged on the outlet seawater pipeline. After heat exchange with seawater, the fluorine refrigerant comes out of the top of the condenser and goes back to the upper left side of the cabinet through the pipe. It passes through the liquid indicator mirror, the stop valve, the filter dryer, the refrigeration solenoid valves 1119 and 1120, the thermal expansion valves 1104 and 1105, and enters the brazed plate evaporators 1106 and 1107 to exchange heat with the ethylene glycol coolant. Considering that the liquid cooling carrier is an ethylene glycol solution, which has a certain corrosiveness to non-ferrous metals, and the upper left side of the device shares space with the environmental control module control box 2 and the refrigeration compressors 1101 and 1102, the overall size of the two sets of evaporators 1106 and 1107 is controlled within the space of 200mm×300mm×400mm. The design uses a compact 316 stainless steel brazed plate evaporator. At the same time, the heat exchange capacity index of a single evaporator 1106 or 1107 is greater than the compression refrigeration capacity requirement of a single compressor 1101 or 1102.

[0117] The main power module 201, the main electric control board 202 containing the single-chip microcomputer, and the low-voltage control power module 203 are all arranged in the environment control module control box 2, and are connected to each other through cables and signal lines; the touch LCD display screen 204 is arranged on the front panel of the environment control module control box 2; a water leakage detection rope 9 is arranged around the bottom of the frame box 103; the water leakage detection rope 9 around the bottom of the frame box 103 is connected to the environment control module control box 2 through a signal line; all sensors inside the seawater source marine integrated server liquid cooling cooling device 1: inlet seawater temperature sensor 1114, outlet seawater temperature sensor 1115, inlet seawater pressure sensor 1117, liquid supply pipeline water pressure sensor 1204, return liquid pipeline water pressure sensor 1205, liquid supply pipeline outlet temperature sensor 1206, return liquid pipeline temperature sensor 1207, electromagnetic flow sensor 1208, third pressure sensor 1215 and fourth The pressure sensor 1216 at the filter outlet main pipe and the pressure sensor 1224 of the liquid supply pipeline system are connected to the environment control module control box 2 through signal lines; all the electrically driven components inside the seawater source marine integrated server liquid cooling and refrigeration device 1: refrigeration compressor 1101, refrigeration compressor 1102, hot gas bypass valve group 1108, hot gas bypass valve group 1109, hot gas bypass valve group 1110, hot gas bypass valve group 1111, refrigeration solenoid valve 1119, refrigeration solenoid valve 1120, ethylene glycol liquid supply circulation pump 1202, ethylene glycol liquid supply circulation pump 1203, electric bypass valve 1203, filter inlet electric butterfly valve 1211, filter outlet electric butterfly valve 1212, filter inlet electric butterfly valve 1213, filter outlet electric butterfly valve 1214, liquid replenishment pump 1221, automatic water replenishment valve 1225, automatic water replenishment valve 1226 are all connected to the environment control module control box 2 through signal control lines.

[0118] Here, the constant pressure liquid replenishment and exhaust component, one of the main component systems of the glycol cooling module 102, is mainly arranged in the upper right area of ​​the cabinet, and is mainly composed of a liquid adding tank 1218, a liquid level sensor 1219 on the liquid adding tank 1218, a closed expansion tank 1220, a liquid replenishment pump 1221, a water replenishment filter 1222, an automatic exhaust valve 1223, a liquid supply pipeline system pressure sensor 1224, automatic water replenishment valves 1225 and 1226, and supporting pipelines, etc. There is an inflatable diaphragm in the closed expansion tank 1220. When the pressure in the system increases due to temperature changes, the water in the system enters the expansion tank 1220, and the diaphragm contracts at the same time, and the pressure on both sides of the diaphragm is balanced. When the pressure in the system decreases due to temperature changes, the water in the expansion tank 1220 enters the system, and the diaphragm expands at the same time, and the pressure on both sides of the diaphragm is balanced, so that the system pressure can be automatically stabilized. When the system is in normal use, the gas in the glycol cooling module 102 can be effectively exhausted through the automatic exhaust valve 1223. The constant pressure liquid replenishment exhaust component also has the function of automatically replenishing liquid when it detects possible leakage and causes the flow pressure to be too low. The specific logic is described in Example 4.

[0119] like Figure 3As shown, the environment control module control box 2 is arranged on the left outer side of the cabinet 103, and is mainly composed of a main power module 201, a main electric control board 202 containing a single-chip microcomputer, a low-voltage control power module 203, a touch LCD screen 204, an external sampling sensor, etc. The main electric control board 202 is designed in accordance with the military environment control equipment standard, meets the working temperature of -40℃~+55℃, uses a high-speed MCU embedded single-chip microcomputer to process data, and the input interfaces are all equipped with necessary abnormal protection devices. The circuit board PCB material is a FR-4 epoxy glass fiber cloth laminate with high thermal stability and high mechanical strength. All interfaces are arranged on the front, and the double-sided three-proof glue is filled. The high-rise components are glued and fixed, and have the ability to resist vibration, impact, moisture, salt spray, and mildew, meeting the requirements of marine environmental conditions. The main sampling sensors configured in the device include: a seawater temperature sensor 1114 installed on the seawater inlet main pipe, which can monitor the inlet seawater temperature; a second seawater temperature sensor 1115 installed on the seawater outlet main pipe, which can monitor the seawater temperature after heat exchange through the condenser 1103; by calculating the difference between the seawater temperature after heat exchange and the inlet seawater temperature, the heat exchange capacity of the device condenser 1103 can be controlled; a second seawater pressure sensor 1116 installed on the seawater inlet main pipe can monitor whether the seawater flows normally into the condenser, which can be used as a check whether the device is normal. One of the necessary parameters for starting operation; the outlet temperature sensor 1206 of the supply line installed on the ethylene glycol coolant water supply main can monitor the temperature of the supply server, which is also the main parameter for the device to adjust the supply temperature; the temperature sensor 1207 installed on the ethylene glycol coolant return main can monitor the temperature of the ethylene glycol coolant after the liquid cooling plate in the server is exchanged; the water pressure sensor 1204 of the supply line installed on the ethylene glycol coolant water supply main can monitor the supply pressure of the ethylene glycol solution, which can be used as the first ethylene glycol supply circulation pump 1201 and the second ethylene glycol supply The electromagnetic flow sensor 1208 installed on the return water main can monitor the total flow of ethylene glycol coolant in real time, and can obtain the load cooling demand of the server by combining it with the difference of the inlet and outlet water temperatures of the ethylene glycol coolant, so as to control the device to adjust the cooling capacity. The third pressure sensor 1215 and the fourth pressure sensor 1216 installed on the inlet / outlet ends of the ethylene glycol coolant filters 1209 and 1210 can monitor the pressure at both ends of the filters and transmit it in real time. The pressure is transmitted to the control box 2 of the environment control module. The control box 2 obtains the pressure drop value of the first ethylene glycol liquid supply circulation pump 1201 and the second ethylene glycol liquid supply circulation pump 1202 by subtracting the two values, and compares them with the recorded initial pressure drop value. When the pressure drop threshold is exceeded, an alarm is issued to display that the first ethylene glycol liquid supply circulation pump 1201 and the second ethylene glycol liquid supply circulation pump 1202 are dirty or blocked, and corresponding measures are automatically initiated to deal with the fault; the pipeline system pressure sensor 1124 installed on the constant pressure pipeline of the device can monitor the minimum pressure value of the ethylene glycol pipeline and can be used as a necessary parameter for whether liquid replenishment is needed;The liquid level sensor 1219 arranged in the liquid adding tank 1218 can monitor the value of the standby ethylene glycol solution in the liquid adding tank 1218. When it is less than the value of the minimum allowable solution amount, it can sound and light alarm to notify the replenishment of liquid; the water leakage detection rope 9 arranged around the bottom of the cabinet 103 can monitor whether there is leakage inside the device; the phase sequence protector in the power supply module can realize the phase loss check when the device is turned on; the environmental control module control box 2 receives the exhaust temperature of the refrigeration compressors 1101 and 1102 respectively through the CAN bus or RS485 interface. The system can detect the alarm of temperature and high and low pressure, overload of glycol liquid supply circulation pumps 1201 and 1202, monitor the operating status and fault information of compressors 1101 and 1102, glycol liquid supply pumps 1201 and 1202, and take corresponding measures for the corresponding faults; the control box 2 of the environmental control module can realize the main fault alarm, automatic standby conversion, and internal leakage of the device through the logic operation of the software by receiving the real-time data transmitted by the above sensors and key components, and finally realize the ability of the device to be unattended and automatically handle major faults. ;

[0120] In this embodiment, by adopting high-efficiency components such as a scroll vertical compressor 1101, a shell and tube condenser 1103 with a double-fluorine-to-seawater heat exchange structure, and small brazed plate evaporators 1106 and 1107, the overall size of the key large-volume components of the device is reduced, and at the same time, the layout positions of the components with a large weight share are reasonably arranged, forming a high-efficiency seawater source marine integrated server liquid cooling device 1 with a compact structure and easy maintenance.

[0121] In this embodiment, necessary sensors are set at key positions inside the seawater source marine integrated server liquid cooling refrigeration device 1 to comprehensively monitor the key operating parameters of the device. The signals of various sensors are transmitted to the environmental control module control box 2 in real time. The algorithm software built into the control box 2 realizes comprehensive and automatic monitoring of the device 1, and can automatically identify major faults and automatically start corresponding fault processing measures, so that the device has the ability of unmanned operation and automatic fault handling.

[0122] Example 3

[0123] On the basis of Example 2, the seawater source compression condensation module 101 adopts a dual-cycle fluorine refrigeration system design, each fluorine refrigeration system includes complete refrigeration compressors 1101 and 1102, condenser 1103, thermal expansion valves 1104 and 1105, evaporators 1106 and 1107, etc. The equipment has two independent fluorine refrigeration systems, which do not interfere with each other during operation. The two circulating fluorine refrigeration systems can achieve high reliability operation with mutual backup through the following logic control:

[0124] Step S1, the environment control module control box 2 is used for initial startup of the equipment, according to the accumulated running time of each of the first refrigeration compressor 1101 and the second refrigeration compressor 1102, to select the one with the shorter accumulated running time of the first refrigeration compressor 1101 and the second refrigeration compressor 1102 to start first;

[0125] Step S2, the environment control module control box 2 is used to automatically calculate the total load heat in the environment control module control box 2 according to the collected temperatures of the liquid supply pipeline outlet temperature sensor 1206 and the return liquid temperature sensor 1207 in the ethylene glycol cooling module 102, and the total liquid supply flow collected by the return liquid flow sensor 1208. When the total load heat is greater than half of the cooling capacity (such as 10kW), the other refrigeration compressor that has not been turned on in the first refrigeration compressor 1101 and the second refrigeration compressor 1102 is turned on; during the operation, when the detected load heat is less than or equal to the cooling capacity, the cooling capacity is turned off. When the capacity is half (tentatively set as 10kW) for more than 3 minutes after the preset time, the operation of one of the refrigeration compressors can be stopped; under normal circumstances, the seawater source compression condensation module 101 selects one of the first refrigeration compressor 1101 and the second refrigeration compressor 1102 with a longer cumulative shutdown time according to the calculated total load heat, and at least one refrigeration compressor is guaranteed to keep running, wherein the first refrigeration compressor 1101 and the second refrigeration compressor 1102 are controlled by the local environment control module control box 2 or receive a stop command issued by the host computer.

[0126] Preferably, the environmental control module control box 2 is used for the following processing logic when the seawater source compression and condensation module 101 fails:

[0127] When only one of the first refrigeration compressor 1101 and the second refrigeration compressor 1102 is in operation, the environment control module control box 2 automatically switches to the other refrigeration compressor when it detects that the running refrigeration compressor is overloaded, over-pressured or has other faults;

[0128] When the first refrigeration compressor 1101 and the second refrigeration compressor 1102 are running at the same time, when the environmental control module control box 2 detects a fault such as overcurrent, overpressure, or fluorine high pressure alarm in the first refrigeration compressor 1101 or the second refrigeration compressor 1102, the environmental module control box 2 stops the corresponding faulty refrigeration compressor and sends an alarm signal to the host computer. During this period, the ethylene glycol cooling module 102 does not stop working.

[0129] In an emergency, manual operation can be used to enter the override mode, in which all protections and program controls are canceled, and the first refrigeration compressor 1101 and / or the second refrigeration compressor 1102 can be directly started manually to provide power for operation.

[0130] In this example, by setting up relatively independent redundant design of key components of the dual-cycle fluorine refrigeration system design configuration, the vitality of the entire module is improved, and the algorithm judgment logic and control logic for corresponding faults are integrated into the software system of the environmental control module control box 2, realizing unattended operation of the seawater source compression condensation module 101 and automatic rapid response processing of key faults.

[0131] Example 4

[0132] On the basis of Example 2, the two ethylene glycol liquid supply circulation pumps 1201 and 1202 of the ethylene glycol cooling module 102 adopt a 1-in-1-standby control mode in the automatic working state, and the specific control logic is:

[0133] The environment control module control box 2 is used to determine whether to start the first ethylene glycol liquid supply circulation pump 1201 or the second ethylene glycol liquid supply circulation pump 1202 with the shorter cumulative operation time first at each startup according to the respective cumulative use time of the first ethylene glycol liquid supply circulation pump 1201 and the second ethylene glycol liquid supply circulation pump 1202;

[0134] After the equipment is powered on, the flow rate and pressure will not be detected within 10 seconds after the first ethylene glycol liquid supply circulation pump 1201 or the second ethylene glycol liquid supply circulation pump 1202 starts running. After 10 seconds, the flow rate alarm and pressure alarm will be detected. The first ethylene glycol liquid supply circulation pump 1201 or the second ethylene glycol liquid supply circulation pump 1202 will not stop running, and the alarm signal will be sent to the host computer;

[0135] When the system is running, when the environment control module control box 2 detects that the started first ethylene glycol liquid supply circulation pump 1201 or the second ethylene glycol liquid supply circulation pump 1202 sends an overload alarm signal, it automatically switches to start the other stopped second ethylene glycol liquid supply circulation pump 1202 or the first ethylene glycol liquid supply circulation pump 1201;

[0136] During the operation of the first ethylene glycol liquid supply circulation pump 1201 or the second ethylene glycol liquid supply circulation pump 1202, only a stop command issued by the host computer is accepted, and the seawater source marine integrated server liquid cooling device 1 cannot decide on its own to stop the ethylene glycol liquid supply circulation pump 1201 or 1202;

[0137] Through the above-mentioned operation logic, it is possible to improve the automatic and rapid dynamic response to solve faults when the ethylene glycol liquid supply circulation pump 1201 or 1202 is in operation, and the operation reliability of the entire equipment is also improved.

[0138] On the basis of Example 2, two ethylene glycol liquid return filters 1209 and 1210 are arranged in parallel on the liquid return main pipe of the ethylene glycol cooling module 102, as well as two pairs of electric butterfly valves 1211 and 1212, 1213 and 1214 at the inlet and outlet of the filters, and ethylene glycol liquid return filter inlet and outlet pressure sensors 1215 and 1216. The third pressure sensor 12155 and the fourth pressure sensor 1216 disposed at both ends of the inlet and outlet of the first ethylene glycol liquid return filter 1209 and the second ethylene glycol liquid return filter 1210 can monitor the pressure values ​​at both ends of the first ethylene glycol liquid return filter 1209 and the second ethylene glycol liquid return filter 1210, and transmit the pressure values ​​to the environmental control module control box 2 in real time. The environmental control module control box 2 obtains the pressure drop values ​​of the first ethylene glycol liquid return filter 1209 and the second ethylene glycol liquid return filter 1210 by subtracting the values ​​at both ends, and compares the pressure drop values ​​with the recorded initial pressure drop values. When the pressure drop exceeds the allowable threshold, an alarm is issued to indicate that the first ethylene glycol liquid return filter 1209 and the second ethylene glycol liquid return filter 1210 are dirty and blocked, and corresponding measures are automatically initiated to deal with the fault. The specific control mode is:

[0139] When the seawater source marine integrated server liquid cooling and cooling device 1 is not started, in the initial detection state, the seawater source marine integrated server liquid cooling and cooling device 1 is stopped from starting and running, an audible and visual alarm is issued, and the cause of the fault is marked on the display screen of the environment control module control box 2;

[0140] When the seawater source marine integrated server liquid cooling refrigeration device 1 is started, during operation, when it is detected that the first ethylene glycol liquid return filter 1209 and the second ethylene glycol liquid return filter 1210 are dirty and blocked, a delay of 2 minutes is given, and an audible and visual alarm is issued to indicate the dirty and blocked faults of the first ethylene glycol liquid return filter 1209 and the second ethylene glycol liquid return filter 1210. At the same time, information is reported to the upper computer, and the server operation status is communicated with the upper computer. If the data server is in operation, all four electric butterfly valves on the inlet and outlet of the first ethylene glycol liquid return filter 1209 and the second ethylene glycol liquid return filter 1210, namely the first electric butterfly valve 1211, the second electric butterfly valve 1212, the third electric butterfly valve 1213 and the fourth electric butterfly valve 1214, are opened, and the ethylene glycol cooling module 102 enters the overcurrent operation state to ensure that the flow meets the server operation requirements. At the same time, the fault display on the screen 204 of the environment control module control box 2 is maintained until the host computer issues a shutdown command, and then the operation of the seawater source marine integrated server liquid cooling device 1 can be stopped to repair the corresponding components.

[0141] The above design can monitor the operating status of the first ethylene glycol liquid return filter 1209 and the second ethylene glycol liquid return filter 1210 in real time, and ensure that when the server is running, if the first ethylene glycol liquid return filter 1209 or the second ethylene glycol liquid return filter 1210 fails, it can be automatically and quickly resolved dynamically.

[0142] On the basis of Example 2, the liquid supply pipeline system pressure sensor 1224 in the constant pressure liquid replenishment exhaust component transmits the system pipeline pressure to the environmental control module control box 2 in real time. When the ethylene glycol solution in the system is reduced due to leakage or other reasons, resulting in a low system pressure, the pipeline system pressure will decrease. At this time, the environmental control module control box 2 will compare the real-time pipeline pressure value of the system pressure sensor 1224 with the set pipeline pressure threshold. When it is lower than the threshold, the liquid replenishment pump 1221, the first automatic water replenishment valve 1225 and the second automatic water replenishment valve 1226 will be automatically opened after a delay of 10 minutes to replenish the ethylene glycol solution in the liquid filling tank 1218 into the system pipeline; when the pipeline pressure monitored in real time returns to the threshold, the pressure If the pressure is above the set value, the liquid replenishment pump 1221 is stopped and the first automatic water replenishment valve 1225 and the second automatic water replenishment valve 1226 are closed; if within 30 minutes, the pipeline pressure is lower than the set threshold again, the environmental control module control box 2 will send out an audible and visual alarm, and send a leakage alarm signal to the upper computer. At this time, the data server is running, and the equipment will continue to run without stopping; when the seawater source marine integrated server liquid cooling device 1 is not running, the environmental control module control box 2 is powered on regularly, and the leakage detection rope 9 described in Example 2 is self-checked. When there is liquid leakage at the bottom of the frame box 103, the control box 2 will sound and light alarm and display the internal pipeline of the device and indicate that there may be leakage, and send fault information to the upper computer. The above design realizes comprehensive automatic monitoring of leakage faults of the device 1 and automatic and rapid response to solve faults during operation.

[0143] In this example, the key function of the ethylene glycol cooling module 102 is to ensure continuous supply of ethylene glycol coolant to the server at a flow rate that meets the server's operating requirements. The main key faults that affect this function of the entire ethylene glycol cooling module 102 are of three types: failure of the ethylene glycol supply circulation pump 1201 or 1202, blockage of the ethylene glycol main filter 1209 or 1210, and leakage of the ethylene glycol coolant pipeline. In view of these three types of key faults, necessary redundant designs were made for the key components associated with these three types of faults during the design, and sensors and automatic execution components for real-time monitoring of key parameters were added. The algorithm judgment logic and control logic for the corresponding faults were integrated into the software system of the environmental control module control box 2, realizing unattended module operation and automatic rapid response processing of key faults.

[0144] Example 5

[0145] On the basis of Example 2, a control method for regulating the temperature value of the ethylene glycol coolant for the server is also provided. The device described in Example 2 is used, and the specific implementation method is as follows:

[0146] Step S1, the environment control module control box 2 is used to collect the temperature values ​​of the liquid supply pipeline outlet temperature sensor 1206 and the liquid return temperature sensor 1207 in real time, as well as the total liquid supply flow of the electromagnetic flow sensor 1208 on the liquid return main pipe, and automatically calculate the total load heat. When the load heat is greater than the first preset threshold, such as the load heat>10kW, the other fluorine refrigeration system of the seawater source compression condensation module 101 is turned on; during operation, when it is detected that the load heat is less than or equal to the first preset threshold, the load heat is ≤10kW for more than 3 minutes, the second fluorine refrigeration system of the seawater source compression condensation module 101 can be stopped to ensure that the overall refrigeration capacity of the device matches the load heat;

[0147] Step S2, the environment control module control box 2 is used to open the parallel double hot gas bypass pipelines and the first hot gas bypass valve group 1108 and the first hot gas bypass valve group 1109 on the Freon refrigerant pipeline at the outlet of the running first vertical scroll compressor 1101 when the supply liquid temperature is still higher than the set temperature after the adjustment of the above-mentioned fluorine refrigeration system is completed, or open the parallel double hot gas bypass pipelines and the second hot gas bypass valve group 1110 and the second hot gas bypass valve group 1111 on the Freon refrigerant pipeline at the outlet of the running second compressor 1102 when the supply liquid temperature is still higher than the set temperature, open the first hot gas bypass valve group or the second hot gas bypass valve group, so that part of the fluorine refrigerant bypasses the plate evaporator and directly enters the inlet of the refrigeration compressor, thereby reducing the heat exchange amount with the ethylene glycol supply liquid, thereby increasing the supply liquid temperature;

[0148] Step S3, the environmental control module control box 2 is used to gradually open the electric bypass valve 1203 between the supply and return liquid mains when the liquid supply temperature is still higher than the set temperature, bypass and reflux a small amount of high-temperature ethylene glycol return liquid to mix with the low-temperature ethylene glycol supply liquid, and appropriately increase the liquid delivery temperature. When the temperature of the ethylene glycol solution monitored by the supply pipeline outlet temperature sensor 1206 is still lower than the data server required temperature, the electric bypass valve 1203 can be opened step by step until the difference between the ethylene glycol supply temperature and the set temperature does not exceed ±2°C.

[0149] Through the above-mentioned stepped temperature control logic, the server can achieve different cooling conditions, and the load heat can range from 10% to 100%, and the ethylene glycol supply temperature can be set within the required range of ±2°C.

[0150] Example 6

[0151] On the basis of Example 2, two sets of condensing pressure regulating valves 1112 and 1113 are arranged in parallel at the seawater inlet of the shell and tube condenser 1103 to adjust the flow rate of cooling seawater entering the condenser 1103 according to the change of condensing pressure. The first condensing pressure regulating valve 1112 and the second condensing pressure regulating valve 1113 control the flow rate of cooling seawater by changing the opening degree of the first condensing pressure regulating valve 1112 and the second condensing pressure regulating valve 1113 by directly sensing the condensing pressure of the fluorine refrigerant in the shell and tube condenser 1103. When the condensing pressure in the condenser 1103 increases (i.e., the condensing pressure increases), the flow area of ​​the valve core is automatically opened to allow more cooling seawater to enter the condenser 1103, thereby accelerating the condensation speed of the fluorine refrigerant and reducing the pressure value in the condenser 1103 to return to the set value. On the contrary, when the condensing pressure decreases, the first condensing pressure regulating valve 1112 and the second condensing pressure regulating valve 1113 are automatically closed to reduce the amount of cooling seawater entering the condenser 1103, thereby maintaining the condensing pressure within a certain range. Through this thermal feedback system, no matter how the external seawater temperature changes, the condensing temperature in the condenser 1103 is controlled within the range of 40°C±2°C.

[0152] On the basis of Example 2, the first thermal expansion valve 1104 and the second thermal expansion valve 1105 are arranged on the inlet pipelines of the plate-type first evaporator 1106 and the second evaporator 1107. The first thermal expansion valve 1104 and the second thermal expansion valve 1105 mainly adjust the flow rate of the system fluorine refrigerant, control the temperature of the fluorine refrigerant in the first evaporator 1106 and the second evaporator 1107, and then control the evaporation temperature at 12°C ± 2°C. The heat exchange capacity of a single expansion valve 1104 or 1105 selected in this device is 18.1kW, and the compression and condensation capacity of a single compressor 1101 or 1102 is about 2 / 3 of the range, and has a 1 / 3 margin adjustment capability.

[0153] In this example, a suitable first thermal expansion valve 1104 is designed and selected to control the evaporation temperature of the first evaporator 1106 to fluctuate within a preset effective range; the second thermal expansion valve 1105 controls the evaporation temperature in the second evaporator 1107 to fluctuate within a preset effective range; the first condensation pressure regulating valve 1112 and the second condensation pressure regulating valve 1113 are selected and arranged in parallel to enhance their ability to regulate the flow of cooling seawater, so that the condensation temperature in the condenser 1103 is stabilized within the effective range; and thus the entire set of seawater source marine integrated server liquid cooling refrigeration device 1 can stably operate in a refrigeration condition when the external environment temperature changes throughout the year and in global shipping, especially when the seawater temperature varies in a wide range from 2°C to 40°C, to meet the cooling needs of the data server throughout the year.

[0154] In summary, the present invention provides a cabin environment control system for a ship data center, including: mainly a seawater source ship integrated server liquid cooling device, an environment control system control box, a terminal control unit, a ship data center seawater source air conditioner, ventilation facilities and various external sensors.

[0155] The present invention integrates a variety of air conditioning and ventilation means, and through the environmental control system control box, it realizes comprehensive monitoring and effective control of key parameters such as air temperature, humidity, cleanliness, etc. in the cabin of the ship data center, and at the same time has the ability to automatically and quickly respond to emergency accidents such as key equipment failures and fire damage; by developing a compact seawater source marine integrated server liquid cooling cooling device with high reliability, unattended operation, and automatic and rapid dynamic response to major faults, it provides ethylene glycol coolant for cooling, meeting the requirements of internal cooling and heat dissipation of the cabin server of the ship data center. The whole system is designed through redundancy, simplification, robustness, corrosion and leakage prevention, human engineering design, and dynamic response design, forming a new type of ship data center cabin environment control system suitable for the marine environment of ships, with seawater as the basic cold source, for the internal cooling of the cabin server of the ship data center, with high reliability, sustainable cooling in all seasons and global operating environment conditions.
