[0034] This embodiment provides a refrigeration system for cooling water to form chilled water.

[0035] Specifically, in combination Figure 1-6 As shown, a refrigeration system includes a housing 1, a first refrigeration unit, and a second refrigeration unit. The first refrigeration unit includes a first refrigeration component and a first water pump 31 connected to the first refrigeration component. The second refrigeration unit includes a second refrigeration component and a second water pump 41 connected to the second refrigeration component. Both the first and second refrigeration units are integrated into the housing 1, and their layouts are independent. The first and second refrigeration components share a common power source.

[0036] The refrigeration system in this design includes a first refrigeration unit and a second refrigeration unit. Using two refrigeration units for simultaneous cooling improves the system's cooling capacity. The first and second refrigeration units are rationally arranged, with each component operating independently and without interference, allowing each unit to perform its own cooling function and increasing system redundancy. The refrigeration system is integrated into the housing 1, maximizing space utilization and improving overall system integration. The first and second refrigeration units share a single power source, reducing the need for separate power sources and ensuring synchronous cooling operation.

[0037] See Figure 5 and Figure 6As shown, as a further improvement, the first refrigeration assembly includes a first compressor 33, a first heat exchanger 32, a first expansion valve 35, and a first condenser 61 connected in sequence by pipelines. The second refrigeration assembly includes a second compressor 43, a second heat exchanger 42, a second expansion valve 45, and a second condenser 62 connected in sequence by pipelines. The specific refrigeration process is described using the first refrigeration assembly. The refrigerant, for example, R407c, enters the first heat exchanger 32 after passing through the first compressor 33, where heat exchange occurs, thus achieving refrigeration. Afterward, it enters the first expansion valve 35 and then the first condenser 61 for heat dissipation. The refrigeration process of the second refrigeration assembly is the same as that of the first refrigeration assembly.

[0038] Preferably, a first liquid receiver 34 is also connected between the first expansion valve 35 and the first condenser 61; a second liquid receiver 44 is also connected between the second expansion valve 45 and the second condenser 62. In the first refrigeration assembly, the first liquid receiver 34 buffers and stores the refrigerant. Since the refrigerant pressure changes after passing through the first expansion valve 35, the first liquid receiver 34, positioned between the first expansion valve 35 and the first condenser 61, also helps stabilize the pipeline pressure. Similarly, the function of the second liquid receiver 44 in the second refrigeration assembly is the same as that of the first liquid receiver 34 in the first refrigeration assembly.

[0039] Regarding the configuration of the first water pump 31 and the second water pump 41, the outlet of the first water pump 31 is connected to the inlet of the first heat exchanger 32. The outlet of the second water pump 41 is connected to the inlet of the second heat exchanger 42.

[0040] More specifically, taking the configuration of the first water pump 31 as an example, a first filter 3 is also installed on the housing 1 to filter the medium to be cooled, such as liquid water. After the first water pump 31 is started, the water passes through the first filter 3 and enters the first heat exchanger 32 through the outlet of the first water pump 31. In the first heat exchanger 32, the water exchanges heat with the refrigerant, thereby cooling the water to obtain cooling water. Similarly, a second filter 4 is also installed on the housing 1. The second filter 4 is connected to the second water pump 41, and the water flow and cooling process are consistent with those in the first refrigeration assembly.

[0041] See Figure 2 and Figure 3 In this embodiment, the first and second refrigeration components share a single power source, which is an engine. Specifically, both the first compressor 33 and the second compressor 43 are connected to the engine 5. The same engine 5 simultaneously drives the first compressor 33 and the second compressor 43, enabling them to operate at the same frequency and reducing the number of power sources required.

[0042] In one preferred embodiment, the first condenser 61 includes a main liquid inlet pipe and a main liquid outlet pipe. The main liquid inlet pipe is connected to the inlet of several branch pipes, and the outlet of the branch pipes is connected to the main liquid outlet pipe after multiple bends. The second condenser 62 has the same structure as the first condenser 61.

[0043] See Figure 3 and Figure 4 Specifically, the first condenser 61 is used as an example. The main liquid inlet pipe in the first condenser 61 is called the liquid inlet pipe 611, and the main liquid outlet pipe is called the liquid outlet pipe 612. Several branch pipes are connected to the liquid inlet pipe 611. After several bends, the branch pipes connect to the liquid outlet pipe 612. The liquid inlet pipe 611 and the liquid outlet pipe 612 are located on the same side.

[0044] Preferably, the first refrigeration component and the second refrigeration component are disposed on the same side near the housing 1; the first condenser 61 and the second condenser 62 are disposed on the same side near the housing 1; so that sufficient space can be reserved on the other side of the housing for installing the engine 5.

[0045] In addition, each of the first condenser 61 and the second condenser 62 is provided with a cooling fan 2 to dissipate heat from the refrigerant flowing into the first condenser 61 and the second condenser 62 in a timely manner.

[0046] The first compressor 33, the second compressor 43, and the engine 5 are all mounted on a platform support, which is located at the bottom of the housing 1. Elastic supports are installed below the platform support to provide vibration damping. When the first compressor 33, the second compressor 43, and the engine 5 are running, the elastic supports reduce vibration.

[0047] The terms “installation,” “setup,” “equipped with,” and “connection” used herein should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0048] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
