Specifically, the refrigeration unit 41 of this utility model is a screw refrigeration unit 41 or a centrifugal refrigeration unit 41. A switch is installed on container 1, and the switch is electrically connected to distribution cabinet 45. The outlet of cooling tower 2 is connected to one end of cooling water circulation pump 42 through cooling water pipeline 3. The other end of cooling water circulation pump 42 is connected to refrigeration unit 41 to realize the connection between refrigeration unit 41 and cooling tower 2. Terminal return water pipeline is connected to the inlet of chilled water circulation pump 43 through chilled water pipeline 44. The outlet of chilled water circulation pump 43 is connected to the inlet of refrigeration unit 41 through chilled water pipeline 44. The outlet of refrigeration unit 41 is connected to terminal water supply pipeline 46 to form a refrigeration circuit. This utility model integrates the refrigeration unit 41, cooling water circulation pump 42, chilled water circulation pump 43, chilled water pipeline 44, power distribution cabinet 45, terminal return water pipeline, and terminal supply water pipeline 46 into the container 1. This reduces the pressure drop of the exhaust pressure of the refrigeration unit 41, making the refrigeration unit 41 more efficient. It also improves the reliability and stability of the refrigeration unit 41. Users only need to connect the power supply and connect the first connecting water pipe and the second connecting water pipe through the first connection port 11 and the second connection port 12 on the side wall of the container 1 to start the integrated container refrigeration unit for refrigeration. There is no need to assemble the refrigeration unit 41, cooling water circulation pump 42, chilled water circulation pump 43, and chilled water pipeline 44 on-site, which improves installation efficiency, reduces the workload of workers, and reduces the difficulty of operation for workers.

[0031] In other embodiments, the container 1 includes a base plate, and the refrigeration unit 41 is bolted to a prefabricated pipe. A circulation pipe that works in conjunction with the cooling water circulation pump 42 can also be installed inside the cooling tower 2. The cooling water circulation pump 42 circulates the cooling water, effectively protecting the efficient operation of the cooling tower 2, allowing for water recovery, low energy consumption, and a long service life.

[0032] In a specific implementation of this utility model, the terminal water supply pipeline 46 includes a terminal water supply pipe 461, a first temperature sensor 462, a water flow switch 463, and a return water pressure gauge 464.

The chilled water pipe 413 and the cooling water pipe 414 facilitate the evaporator to remove the heat generated during the cooling water circulation process of the condenser 412. The chilled water and cooling water flow between the evaporator and the condenser 412 through the chilled water pipe 413 and the cooling water pipe 414. This invention utilizes a chilled water circulation pump 43 to supply chilled water returning from the terminal equipment to the evaporator of the refrigeration unit 41 for cooling. Positioning the chilled water circulation pump 43 at the inlet of the refrigeration unit 41 ensures a stable chilled water supply and meets the cooling requirements of the refrigeration unit 41. A cooling water circulation pump 42 circulates cooling water returning from the cooling tower 2 to the condenser 412 of the refrigeration unit 41 to remove heat generated by the refrigeration unit 41. Positioning the cooling tower 2 at the inlet of the refrigeration unit 41 ensures a stable water supply and meets the cooling requirements of the refrigeration unit 41. By placing the chilled water circulation pump 43 and the cooling water circulation pump 42 at the inlet of the refrigeration unit 41, this invention effectively controls the cooling effect of the refrigeration unit 41 and ensures that the supply and temperature of cooling water and chilled water meet the requirements.

[0034] In specific implementation, the cooling water pipeline 3 of this utility model includes a cooling water supply pipeline 31 and a cooling water return pipeline 32. One end of the cooling water supply pipeline 31 is connected to the outlet end of the cooling tower 2, and the other end of the cooling water supply pipeline 31 is connected to the cooling water circulation pump 42 and the refrigeration unit 41. One end of the cooling water return pipeline 32 is connected to the outlet end of the refrigeration unit 41, and the other end of the cooling water return pipeline 32 is connected to the inlet end of the cooling tower 2. A first filter 33 is installed on the cooling water supply pipeline 31. The cooling water supply pipeline 31 filters impurities in the cooling water transportation process through the first filter 33 to prevent impurities from entering the cooling water circulation pump 42.

[0035] In this invention, one end of the chilled water pipe 44 is connected to the water inlet of the refrigeration unit 41, and the other end of the chilled water pipe 44 is connected to the end return water pipe.

[0036] In its specific implementation, the refrigeration device 4 of this utility model includes an expansion tank 47 and a circulating water outlet pipe 48. One end of the circulating water outlet pipe 48 is connected to the expansion tank 47, and the other end is connected to the chilled water pipe 44. The expansion tank 47 is connected to the chilled water pipe 44 through the circulating water outlet pipe 48. The expansion tank 47 ensures sufficient water in the refrigeration circuit and maintains the normal suction pressure of the chilled water circulation pump 43. The expansion tank 47 is also connected to a water supply pipe 471. A float valve 472 is installed inside the expansion tank 47. The water supply pipe 471 is connected to the municipal water supply network to replenish water to the expansion tank 47, so that the water level in the expansion tank 47 is maintained at the required height.

[0037] The refrigeration process for integrated container refrigeration units includes the following steps:

[0038] First, connect the first and second connecting water pipes of container 1 to the building;

[0039] Secondly, the container 1 is connected to the cooling tower 2 via the cooling water pipe 3;

[0040] Then, turn on the switch of the integrated container refrigeration unit;

[0041] Finally, the cooling water cooled by the cooling tower 2 is sent to the condenser 412 of the chiller unit 41 through the cooling water supply pipe 31 and the cooling water circulation pump 42, where it exchanges heat with the refrigerant in the condenser 412 and then flows out of the condenser 412. The cooling water flowing out of the condenser 412 flows back into the cooling tower 2 through the cooling water recovery pipe, where the heat is dissipated. The cooled water then re-enters the condenser 412 of the chiller unit 41 through the cooling water supply pipe 31 and the cooling water circulation pump 42, thus continuously circulating the cooling system. The chilled water circulating in the refrigeration loop flows out of the evaporator of the chiller unit 41. The chilled water flowing out of the evaporator enters the air conditioning terminal equipment through the terminal return water pipe. After the air conditioning terminal equipment exchanges heat with the air in the building, the chilled water flows through the terminal return water pipe and the chilled water return pipe through the chilled water circulation pump 43 and flows back into the evaporator of the chiller unit 41, where it exchanges heat with the refrigerant in the evaporator inside the chiller unit 41, thus continuously circulating the cooling system.
