Detailed Implementation

[0070] In view of this, the present invention provides a refrigeration unit and a refrigeration environment space, which not only does not interfere with the refrigeration environment space, but also enables the refrigeration environment space to discharge exhaust gas and harmful gases, thus making it more suitable for practical use.

[0071] To further illustrate the technical means and effects adopted by the present invention to achieve the intended purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation, structure, features, and effects of a refrigeration unit and refrigerated environment space proposed according to the present invention. In the following description, different "embodiments" or "embodiments" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0072] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that there can be three relationships, such as A and / or B. Specifically, it can mean that A and B can be included at the same time, A can exist alone, or B can exist alone, and any of the above three situations can be met.

[0073] Refrigeration Unit Example

[0074] The refrigeration unit provided by the present invention includes a casing 1, a condenser 2, a heat dissipation coil 3, a cooling medium inlet pipe 4, and a cooling medium outlet pipe 5. The casing 1 is enclosed and has a first accommodating space 6 inside. The condenser 2 and the heat dissipation coil 3 are disposed in the first accommodating space 6. The cooling medium inlet pipe 4 passes through the casing 1, and one end of the cooling medium inlet pipe 4 is connected to the condenser 2, while the other end is connected to the outside. The cooling medium outlet pipe 5 passes through the casing 1, and one end of the cooling medium outlet pipe 5 is connected to the condenser 2, while the other end is connected to the outside. One end of the heat dissipation coil 3 is connected to the condenser 2, and the other end of the heat dissipation coil 3 is connected to the cooling medium outlet pipe 5 through a tee 7.

[0075] The refrigeration unit provided in this embodiment of the invention inputs cooling medium into the condenser 2 and the heat dissipation coil 3 through the cooling medium inlet pipe 4. The cooling medium is output through the heat dissipation coil 3 and the cooling medium outlet pipe 4. Furthermore, the condenser 2, the input end of the cooling medium inlet pipe 4, the output end of the cooling medium outlet pipe 5, and the heat dissipation coil 3 are all disposed within a closed housing 1. Therefore, it not only does not interfere with the refrigeration environment space, but also avoids the emission of exhaust gas and harmful gases into the refrigeration environment space.

[0076] The refrigeration unit also includes a cooling medium. The cooling medium enters the condenser 2 from the cooling medium inlet pipe 4 and then splits into two paths. One path enters the heat dissipation coil 2 and then flows into the cooling medium outlet pipe 5, while the other path flows directly into the cooling medium outlet pipe 5. In this embodiment, the cooling medium can be water or other refrigerants with a high specific heat. Because water or other refrigerants with a high specific heat have high temperature stability, they offer higher cooling efficiency and a more ideal cooling effect.

[0077] The heat dissipation coil 3 is attached to the inner wall of the outer casing 1. In this case, the contact distance between the heat dissipation coil 3 and the cooling environment is shorter, thus improving the cooling efficiency.

[0078] The outer casing 1 includes a top 8, a body 9, and a bottom plate 10. The top 8 is arched and is fixedly connected to the upper edge of the body 9 via its edge. The transition section 11 connecting the top 8 and the upper edge of the body 9 has rounded corners. The bottom plate 10 encloses the bottom edge of the body 9. The cooling medium inlet pipe 4 passes through the bottom plate 10, and the cooling medium outlet pipe 5 passes through the bottom plate. In this configuration, the outer casing 1 has a streamlined shape, which reduces the airflow interference of the refrigeration unit on the refrigerated environment.

[0079] The housing 1 is integrally formed. In this case, the streamlined design of the housing can be further enhanced, and since there are no connecting joints, stress concentration can be reduced, thus further reducing the airflow interference of the refrigeration unit on the refrigerated environment.

[0080] The refrigeration unit also includes two connectors 12. Each connector 12 includes a first pipe section 13, an annular gasket 14, and a second pipe section 15. The first pipe section 13 is fixedly connected to the inner wall of the annular gasket 14 via its bottom edge, and the second pipe section 15 is fixedly connected to the inner wall of the annular gasket 14 via its top edge. An annular boss 16 is provided inwardly on the bottom edge of the second pipe section 15. The connector is tightly fitted with the cooling medium inlet pipe 4 and / or the cooling medium outlet pipe 5 via the annular boss 16. The base plate 10 is provided with a first through hole and a second through hole. The diameter of the first through hole is equal to the outer diameter of the first section of pipe 13, and the diameter of the second through hole is equal to the outer diameter of the first section of pipe 13. The inner edge of the first through hole abuts against the upper surface of the annular gasket 14 of one of the connectors 13, and the inner edge of the second through hole abuts against the upper surface of the annular gasket 14 of the other connector. The cooling medium inlet pipe 4 passes through the core hole 17 of one of the connectors 12, and the cooling medium outlet pipe 5 passes through the core hole 17 of the other connector 12. In this case, the two connectors 12 can ensure a good seal at the connection between the cooling medium inlet pipe 4, the cooling medium outlet pipe 5 and the refrigeration unit.

[0081] The tight fit is either welded or an interference fit. In this case, the risk of gas or liquid media in the first accommodating space 6 of the housing 1 leaking from the connection between the second section pipe and the cooling medium inlet pipe 4 and / or the cooling medium outlet pipe 5 can be avoided.

[0082] The refrigeration unit also includes a first plug 18, a connecting flange 19, and a second plug 20. The first plug 18 is fixedly connected to one end of the connecting flange 19, with the other end within the first accommodating space 6. The second plug 20 is fixedly connected to the other end of the connecting flange 19, with the other end outside the first accommodating space 6. A third through hole is provided on the base plate 10. The outer diameter of the other end of the first plug 18 is equal to the diameter of the third through hole. The connecting flange 19 is larger than the diameter of the third through hole, such that the inner edge of the third through hole abuts against the upper surface of the connecting flange 19. This configuration avoids the risk of gas or liquid media leaking from the electrical plug.

[0083] In this configuration, the first plug 18 and / or the second plug 20 are aviation plugs. This design allows for a more reliable electrical connection.

[0084] The refrigeration unit also includes a filter structure 21. A fourth through-hole is provided on the base plate 10, and the filter structure 21 is located below the fourth through-hole. In this configuration, the filter structure 21 provides pressure-relieving micropores, allowing pressure to be released when there is a slight positive pressure inside the housing 1.

[0085] The filtration structure includes a first-stage filter layer 22, a second-stage filter layer 23, and a third-stage filter layer 24. A first buffer space 25 is provided between the first-stage filter layer 22 and the second-stage filter layer 23, and a second buffer space 26 is provided between the second-stage filter layer 23 and the third-stage filter layer 24. In this configuration, not only is the filtration effect of the filtration structure 21 guaranteed, but the first buffer space 25 and the second buffer space 26 also ensure reliable pressure relief when positive pressure occurs inside the housing 1.

[0086] The refrigeration unit also includes: a gas concentration sensor for sensing the concentration data of the gas obtained from refrigerant evaporation; and / or a humidity sensor for sensing humidity data; the gas concentration sensor and / or humidity sensor are located at the fourth through hole. In this configuration, the refrigerant and / or water vapor sealing effect within the housing can be monitored in real time.

[0087] The refrigeration unit also includes an alarm signal display device, which triggers an alarm when the data sensed by the gas concentration sensor and / or humidity sensor exceeds a threshold. In this case, if refrigerant and / or water vapor leaks, the alarm signal display device will issue an alarm signal, prompting personnel to carry out timely maintenance.

[0088] Cooling Environment Space Implementation Examples

[0089] The refrigeration environment space provided in this embodiment of the invention includes a floor 27 and a refrigeration unit provided by this invention. A second accommodating space 28 is provided below the floor. The refrigeration unit is fixedly connected to the floor 27 via a base plate 10, and the components located below the base plate 10 are accommodated within the second accommodating space 28. In this configuration, the formation of the refrigeration environment space provided in this embodiment of the invention becomes more convenient.

[0090] The refrigerated environment space also includes a sealing gasket 29. The sealing gasket 29 is disposed between the base plate 10 and the floor 27. In this case, the risk of refrigerant leakage through the connection between the refrigeration unit and the floor 27 can be avoided.

[0091] The floor 27 is equipped with a ventilation mechanism, which allows for pressure release should positive pressure occur in the second accommodating space 28. This ensures stable pressure within the second accommodating space, thereby guaranteeing the safety of the refrigerated environment.
