[0040] Please refer to Figures 1 to 5 The embodiment of the present application provides a refrigeration system integrated skid 100 for use in a data center. The refrigeration system integrated skid 100 includes a base 11, a plate heat exchanger 12, a liquid cooling primary side water pump 13, a cooling water pump 14, an auxiliary device 15, a first connecting pipe 16, a second connecting pipe 17, a third connecting pipe 18, and a fourth connecting pipe 19. The plate heat exchanger 12, the liquid cooling primary side water pump 13, the cooling water pump 14, and the auxiliary device 15 are all disposed on the base 11.

[0041] The plate heat exchanger 12 has the characteristics of high heat exchange efficiency, small heat loss, and compact structure.

[0042] Please refer to Figure 1 and Figure 2 One end of the first connecting pipe 16 is connected to the liquid cooling primary side inlet of the plate heat exchanger 12; one end of the second connecting pipe 17 is connected to the liquid cooling primary side outlet of the plate heat exchanger 12; one end of the third connecting pipe 18 is connected to the cooling water inlet of the plate heat exchanger 12. Please refer to Figure 3 and Figure 4 One end of the fourth connecting pipe 19 is connected to the cooling water outlet end of the plate heat exchanger 12 ; the liquid-cooled primary side water pump 13 is arranged in the first connecting pipe 16 , and the cooling water pump 14 is arranged in the third connecting pipe 18 .

[0043] In the present application, the plate heat exchanger 12, the liquid-cooled primary side water pump 13, the cooling water pump 14 and the auxiliary equipment 15 are integrated on the base 11, the first connecting pipe 16, the second connecting pipe 17, the third connecting pipe 18 and the fourth connecting pipe 19 are connected to the plate heat exchanger 12, the liquid-cooled primary side water pump 13 is arranged in the first connecting pipe 16, and the cooling water pump 14 is arranged in the third connecting pipe 18. They can be prefabricated in the factory, assembled and debugged in advance, and transported as a whole. At the construction site, only the interface connection can be carried out, which greatly reduces the workload at the construction site and shortens the delivery cycle.

[0044] In some embodiments, at least one of the first connecting pipe 16 , the second connecting pipe 17 , the third connecting pipe 18 and the fourth connecting pipe 19 may be provided with a pressure sensor, a temperature sensor or other functional detection components to meet different usage requirements.

[0045] The first connecting pipe 16 and the second connecting pipe 17 constitute a part of the liquid cooling primary side circulation pipe 51, and the third connecting pipe 18 and the fourth connecting pipe constitute a part of the cooling water circulation pipe 52. In the refrigeration system of the data center, Figure 6 As shown, the liquid cooling cabinet side 300 is connected to the heat exchanger 400 through the liquid cooling secondary side circulation pipe 53, the heat exchanger 400 is connected to the plate heat exchanger 12 through the liquid cooling primary side circulation pipe 51, and the plate heat exchanger 12 is connected to the cooling tower 200 through the cooling water circulation pipe 52.

[0046] According to some embodiments of the present application, the auxiliary equipment 15 includes one or more combinations of a constant pressure water replenishing device (not shown in the figure), an automatic dosing device 151 and a sand filtering device 152 .

[0047] The constant pressure water replenishment device is used to provide water replenishment and constant pressure for the liquid cooling primary side circulation system to meet the pressure stability requirements of the refrigeration system.

[0048] The constant pressure water replenishment device is used as a pressure stabilizing expansion water replenishment device in heating and air conditioning systems to play a pressure stabilizing role. Working principle: In a closed-loop system, in order to ensure the stability of the system pressure, an adjustable expansion facility is required. When the system pressure decreases, the water chamber pressure of the pressure tank connected to it also decreases, the volume of the air chamber expands, and the pressure also decreases. When the control system sets a lower limit, the water pump automatically turns on to replenish the system until the set pressure upper limit is reached and the pump stops running. When the water in the system is heated, the temperature rises, the volume expands, the air chamber is squeezed, and the pressure of the pressure system increases. When the limit value is reached, the water in the system enters the expander (or softening water tank) through the safety release device. The system pressure also drops to the set value and stops pressure release, achieving the effect of constant pressure water replenishment. The constant pressure water replenishment device is connected to the liquid cooling primary side circulation pipeline in the refrigeration system integrated skid 100.

[0049] The automatic dosing device 151 is connected to the cooling water circulation pipeline or the liquid cooling primary side circulation pipeline in the refrigeration system integrated skid 100, and is used to add medicine to the liquid cooling primary side circulation system or the cooling water circulation system. The user only needs to place the combined dosing device (the medicine is divided into barrels with different pH value concentrations) in the skid, connect the dosing pipe to the water system, turn on the power to start the operation. During the operation, it automatically detects the pH value of the fluid, intelligently judges and adds the corresponding liquid medicine.

[0050] The automatic dosing device includes a solution tank, a mixer, a metering pump, a Y-type filter, a safety valve, a back pressure valve, a check valve, a pulse damper, a water level gauge, a pressure gauge, a control cabinet, an installation platform, etc. These components are integrated and installed on a base. Users only need to place the automatic dosing device in the dosing room, connect the dosing pipe to the water system, and start the operation by turning on the power supply. During the operation, the pH value of the fluid is automatically detected, the intelligent judgment is made, and the corresponding liquid medicine is added. This factory-based complete set of equipment can greatly reduce the workload of design and on-site construction, basically realize unattended operation, and provide reliable guarantees for the quality, safety and on-site operation of the whole machine.

[0051] The sand filter device 152 is connected to the cooling water circulation pipeline in the refrigeration system integrated skid 100 and is used to filter suspended matter and impurities in the cooling water, mainly targeting fine suspended matter.

[0052] The sand filter device 152 is a water filtration treatment process device using natural quartz sand (usually manganese sand and anthracite) as filter material. The quartz sand filter material is multi-faceted and spherical in appearance, pure white, and has the characteristics of high mechanical strength, strong pollution interception ability, and good acid resistance. Quartz sand is the most widely used filter material, which plays a filtering role, just like water seeping into the ground through sand and gravel, blocking the suspended matter in the water.
