Description

Technical Field

[0001] This utility model relates to the technical field of cold storage refrigeration, specifically to an intelligent dual refrigeration system. Background Technology

[0002] Current cold storage refrigeration systems generally employ two types: direct expansion air-cooled evaporation and secondary cooling. Direct expansion air-cooling utilizes the direct circulation of refrigerant between the indoor and outdoor environments. After compression by the compressor, the refrigerant releases heat in the condenser, then expands through the expansion valve, absorbing heat from the indoor environment in the evaporator, completing the refrigeration cycle. Secondary cooling is an indirect refrigeration method where the refrigerant does not circulate directly between the indoor and outdoor environments. Instead, the refrigerant absorbs heat in the evaporator and then transfers the heat to the outdoor cooling equipment for dissipation.

[0003] Both direct expansion air cooling and air-cooled refrigeration have their own advantages and disadvantages. Direct expansion air cooling is advantageous because it cools quickly, rapidly lowering the temperature inside the cold storage to a stable level, thus maintaining food freshness, and it doesn't require defrosting. Its disadvantages include higher energy consumption, noise levels, and the potential for moisture loss from food surfaces, affecting freshness. Air cooling, on the other hand, consumes less energy, is quieter, and helps retain moisture on food surfaces. Its disadvantages include the need for regular defrosting and a relatively slower cooling speed.

[0004] Therefore, current cold storage facilities, regardless of which refrigeration system they use, will have certain defects and cannot combine all the advantages of both refrigeration systems. Utility Model Content

The evaporator includes dual circulation pipes.

The heat exchanger is connected to one of the circulation pipes of the evaporator via the cooling outlet and cooling circuit.

One port of the four-way valve is connected to the input end of the air-cooling mechanism, and the other port of the four-way valve is connected to the circulation circuit. The circulation outlet and the circulation circuit are respectively connected to both ends of the other circulation pipe of the evaporator.

[0006] A further feature of this invention is that a one-way valve is installed at the output end of both the cooling mechanism and the air-cooling mechanism.

[0007] A further feature of this invention is that a power valve assembly is installed on both the cooling outlet and the circulation outlet, the power valve assembly being used to realize the flow of fluid within the pipeline.

[0009] This utility model also proposes an intelligent dual-refrigeration system, which includes a cooling mechanism, an air-cooling mechanism, a heat exchanger, and an evaporator. The evaporator includes dual circulation pipelines.

[0011] A further feature of this invention is that a power valve assembly is installed on both the cooling outlet and the circulation outlet, the power valve assembly being used to realize the flow of fluid within the pipeline.

It includes an installation frame, in which two circulation pipes are installed. The circulation pipes are arranged in a serpentine pattern. The installation frame is also provided with two sets of fins, and the two circulation pipes are arranged between the two sets of fins.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. By setting up a cooling system and an air-cooling system, the cold storage can be cooled using two separate systems. Initially, the air-cooling system can be used for rapid cooling to quickly reach the designated temperature. Then, the cooling system switches to the cooling system to maintain the temperature, thereby reducing energy consumption and noise, and also minimizing moisture loss from the food surface. When a thick layer of frost forms on the cooling system, the system can switch back to air cooling, stopping the cooling system. Once the frost melts, the system can switch back to the cooling system, eliminating the need for manual defrosting.

[0016] 2. By connecting the circulation loop to the refrigeration outlet, the refrigerant flowing back from the circulation loop can flow into the heat exchanger, thereby allowing the refrigerant to exchange heat with the heat transfer fluid, achieving the purpose of simultaneously driving heat transfer fluid refrigeration and air-cooled refrigeration, further accelerating the refrigeration speed.

[0017] 3. By installing two circulation pipes within the mounting frame, the evaporator can simultaneously meet the cooling requirements of both the cooling load mechanism and the air-cooled mechanism, i.e., direct cooling and indirect cooling. Attached Figure Description

[0025] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0026] Example 1

[0027] This utility model proposes an intelligent dual refrigeration system, which includes a cooling mechanism 1, an air-cooling mechanism 2, a heat exchanger 3, and an evaporator 4. The cooling mechanism 1 is a cooling system, the air-cooling mechanism 2 is a direct expansion air-cooling system, and the evaporator 4 includes a dual circulation pipeline 42, that is, two circulation pipelines 42.

[0028] The output end of the cooling mechanism 1 is connected to a refrigeration outlet 11, and the other end of the refrigeration outlet 11 is connected to one input end of the evaporator 4. The inlet and outlet connecting pipe of the cooling mechanism 1 has a refrigeration circuit 12, and the other end of the refrigeration circuit 12 is connected to one output end of the evaporator 4. That is, the refrigerant in the refrigeration outlet 11 can flow through the evaporator 4 into the refrigeration circuit 12, and then flow back to the cooling mechanism 1 to achieve circulation.

[0029] Another output end of the heat exchanger 3 is connected to a cooling outlet 31, and another input end is connected to a cooling circuit 32. The ends of the cooling outlet 31 and the cooling circuit 32 away from the heat exchanger 3 are respectively connected to a circulation pipe 42 of the evaporator 4. That is, the cooling outlet 31 is connected to one end of the circulation pipe 42, and the cooling circuit 32 is connected to the other end of the circulation pipe 42, thereby realizing the circulation of the cooling refrigerant.

[0030] The heat exchanger 3 enables the heat exchange process between the refrigerant and the secondary refrigerant. The refrigerant absorbs heat from the secondary refrigerant, lowering its temperature. Then, the secondary refrigerant absorbs heat from the environment through the evaporator 4, raising its temperature. This continuous cycle achieves the refrigeration effect.

[0031] The output end of the air-cooled mechanism 2 is connected to the refrigeration outlet 11. A three-way valve 111 is installed on the refrigeration outlet 11. Two of the ports of the three-way valve 111 are connected to the refrigeration outlet 11, and the other port of the three-way valve 111 is connected to the circulation outlet 21. A four-way valve 121 is installed on the refrigeration circuit 12. Two of the ports of the four-way valve 121 are connected to the refrigeration circuit 12. One port of the four-way valve 121 is connected to the input end of the air-cooled mechanism 2, and the other port of the four-way valve 121 is connected to the circulation circuit 22. The ends of the circulation outlet 21 and the circulation circuit 22 away from the air-cooled mechanism 2 are respectively connected to another circulation pipe 42 of the evaporator 4. That is, the circulation outlet 21 is connected to one end of the circulation pipe 42, and the circulation circuit 22 is connected to the other end of the circulation pipe 42.

[0032] By cooperating with the air-cooling mechanism 2, the three-way valve 111 and the four-way valve 121, the refrigerant can circulate in the circulation pipeline 42, thereby achieving the cooling effect.

[0033] Both the cooling unit 1 and the air-cooled unit 2 are equipped with check valves 5 at their output ends. Both the cooling outlet 31 and the circulation outlet 21 are equipped with power valve assemblies 6, which include a circulation pump 61 and various valves for regulating the fluid within the pipeline. Due to different usage conditions, the types of valves installed vary, but the valves for regulating the fluid are standard existing designs and will not be described in detail here. The circulation pump 61 is used to drive the fluid within the pipeline to circulate.

[0034] Both the cooling outlet 31 and the circulation outlet 21 are connected to bypass pipes 7, and each bypass pipe 7 is equipped with a power valve assembly 6. The power valve assembly 6 on the bypass pipe 7 is connected in parallel with the power valve assembly 6 on the corresponding outlet. That is, the power valve assembly 6 on the bypass pipe 7 corresponding to the cooling outlet 31 is connected in parallel with the power valve assembly 6 on the cooling outlet 31, and the power valve assembly 6 on the bypass pipe 7 corresponding to the circulation outlet 21 is connected in parallel with the power valve assembly 6 on the circulation outlet 21. In this way, when performing maintenance on the power valve assembly 6, it can be done without stopping the machine, that is, the maintenance process will not affect the normal cooling.

[0035] Cooling process: Reference Figure 2 Close the connection port of the three-way valve 111 connected to the circulation outlet 21, and open the other two connection ports of the three-way valve 111. Close the two connection ports of the four-way valve 121 connected to the air-cooling mechanism 2 and the circulation loop 22, and open the other two connection ports of the four-way valve 121. At this time, the refrigerant can circulate between the cooling mechanism 1 and the heat exchanger 3 through the cooling outlet 11 and the cooling loop 12. Under the action of the one-way valve 5, the refrigerant in the cooling outlet 11 will not flow to the air-cooling mechanism 2.

[0036] At this time, the power valve group 6 on the cooling outlet 31 is opened, and the circulating pump 61 drives the refrigerant in the cooling outlet 31 and the cooling circuit 32 to circulate between the heat exchanger 3 and the evaporator 4. The refrigerant exchanges heat with the refrigerant in the heat exchanger 3 to cool down, and then absorbs heat and heats up in the evaporator 4 to achieve the purpose of cooling.

[0037] Direct expansion air cooling process: Reference Figure 3Open the three-way valve 111 to connect with the circulation outlet 21, and open the connection port of the three-way valve 111 upstream of the refrigeration outlet 11. Close the connection port of the three-way valve 111 downstream of the refrigeration outlet 11. Open the two connections of the four-way valve 121 to the air-cooling mechanism 2 and the circulation loop 22. Close the other two connections. At this time, the refrigerant can circulate between the air-cooling mechanism 2 and the evaporator 4 through the refrigeration outlet 11, the circulation outlet 21 and the circulation loop 22. At this time, the power valve group 6 on the circulation outlet 21 is opened, and the circulation pump 61 drives the refrigerant to flow. Then, the refrigerant absorbs heat and rises in temperature in the evaporator 4 to achieve the purpose of refrigeration. Under the action of the one-way valve 5, the refrigerant in the refrigeration outlet 11 will not flow to the cooling mechanism 1.

[0038] In the initial stage of the dual refrigeration system operation, the air-cooling mechanism 2 is used to directly expand the air to cool the cold storage room, so as to quickly lower the temperature inside the cold storage room. When the temperature inside the cold storage room reaches the specified value, the cooling mechanism 1 is switched to cool the cold storage room to maintain the temperature inside the cold storage room.

[0039] When the cooling unit 1 needs to be defrosted, the air-cooled unit 2 is replaced to refrigerate the cold storage, causing the cooling unit 1 to stop and the frost on it to melt automatically. After all the frost has melted, the cooling unit 1 is replaced back to refrigerate, which can save the process of manual defrosting.

[0040] Example 2

[0041] This embodiment discloses an intelligent dual-cooling system, including a cooling mechanism 1, an air-cooling mechanism 2, a heat exchanger 3, and an evaporator 4. The cooling mechanism 1 is a cooling system, the air-cooling mechanism 2 is a direct expansion air-cooling system, and the evaporator 4 includes a dual circulation pipeline 42, that is, two circulation pipelines 42.

[0042] The output end of the cooling mechanism 1 is connected to a refrigeration outlet 11, and the other end of the refrigeration outlet 11 is connected to one input end of the evaporator 4. The inlet and outlet connecting pipe of the cooling mechanism 1 has a refrigeration circuit 12, and the other end of the refrigeration circuit 12 is connected to one output end of the evaporator 4. That is, the refrigerant in the refrigeration outlet 11 can flow through the evaporator 4 into the refrigeration circuit 12, and then flow back to the cooling mechanism 1 to achieve circulation.

[0043] Another output end of the heat exchanger 3 is connected to a cooling outlet 31, and another input end is connected to a cooling circuit 32. The ends of the cooling outlet 31 and the cooling circuit 32 away from the heat exchanger 3 are respectively connected to a circulation pipe 42 of the evaporator 4. That is, the cooling outlet 31 is connected to one end of the circulation pipe 42, and the cooling circuit 32 is connected to the other end of the circulation pipe 42, thereby realizing the circulation of the cooling refrigerant.

[0044] The heat exchanger 3 enables the heat exchange process between the refrigerant and the secondary refrigerant. The refrigerant absorbs heat from the secondary refrigerant, lowering its temperature. Then, the secondary refrigerant absorbs heat from the environment through the evaporator 4, raising its temperature. This continuous cycle achieves the refrigeration effect.

[0045] The output end of the air-cooled mechanism 2 is connected to the refrigeration outlet 11. A three-way valve 111 is installed on the refrigeration outlet 11. Two of the connecting ports of the three-way valve 111 are connected to the refrigeration outlet 11, and the other connecting port of the three-way valve 111 is connected to the circulation outlet 21. A three-way valve 122 is installed on the refrigeration circuit 12. Two of the connecting ports of the three-way valve 122 are connected to the refrigeration circuit 12, and the other connecting port of the three-way valve 122 is connected to the input end of the air-cooled mechanism 2. The circulation outlet 21 is connected to another circulation pipe 42 of the evaporator 4, and the other end of the circulation pipe 42 is connected to another circulation pipe 42. The other end of the circulation pipe 42 is connected to the refrigeration outlet 11, and the connection point is located downstream of the three-way valve 111.

[0046] By cooperating with the air-cooling mechanism 2, three-way valve 111 and three-way valve 22, the refrigerant can circulate in the circulation pipeline 42, thereby achieving the cooling effect.

[0047] Both the cooling unit 1 and the air-cooled unit 2 are equipped with check valves 5 at their output ends. Both the cooling outlet 31 and the circulation outlet 21 are equipped with power valve assemblies 6, which include a circulation pump 61 and various valves for regulating the fluid within the pipeline. Due to different usage conditions, the types of valves installed vary, but the valves for regulating the fluid are standard existing designs and will not be described in detail here. The circulation pump 61 is used to drive the fluid within the pipeline to circulate.

[0048] Both the cooling outlet 31 and the circulation outlet 21 are connected to bypass pipes 7, and each bypass pipe 7 is equipped with a power valve assembly 6. The power valve assembly 6 on the bypass pipe 7 is connected in parallel with the power valve assembly 6 on the corresponding outlet. That is, the power valve assembly 6 on the bypass pipe 7 corresponding to the cooling outlet 31 is connected in parallel with the power valve assembly 6 on the cooling outlet 31, and the power valve assembly 6 on the bypass pipe 7 corresponding to the circulation outlet 21 is connected in parallel with the power valve assembly 6 on the circulation outlet 21. In this way, when performing maintenance on the power valve assembly 6, it can be done without stopping the machine, that is, the maintenance process will not affect the normal cooling.

[0049] Cooling process: Close the connection port of three-way valve 111 connected to circulation outlet 21, and open the other two connection ports of three-way valve 111. Close the connection port of three-way valve 222 connected to air-cooling mechanism 2, and open the other two connection ports of three-way valve 222. At this time, the refrigerant can circulate between cooling mechanism 1 and heat exchanger 3 through cooling outlet 11 and cooling circuit 12. Under the action of check valve 5, the refrigerant in cooling outlet 11 will not flow to air-cooling mechanism 2.

[0050] At this time, the power valve group 6 on the cooling outlet 31 is opened, and the circulating pump 61 drives the refrigerant in the cooling outlet 31 and the cooling circuit 32 to circulate between the heat exchanger 3 and the evaporator 4. The refrigerant exchanges heat with the refrigerant in the heat exchanger 3 to cool down, and then absorbs heat and heats up in the evaporator 4 to achieve the purpose of cooling.

[0051] Direct expansion air cooling process: Reference Figure 4 Open the three-way valve 111 to connect with the circulation outlet 21 and the upstream connection port of the three-way valve 111 to the refrigeration outlet 11, close the downstream connection port of the three-way valve 111 to the refrigeration outlet 11, open the three-way valve 222 to connect with the air-cooling mechanism 2 and the upstream connection port of the three-way valve 222 to the refrigeration circuit 12, close the downstream connection port of the three-way valve 222 to the refrigeration circuit 12. At this time, the refrigerant can circulate between the air-cooling mechanism 2, the heat exchanger 3 and the evaporator 4 through the refrigeration outlet 11, the circulation outlet 21, the circulation circuit 22 and the refrigeration circuit 12. At this time, the power valve group 6 on the circulation outlet 21 and the cooling outlet 31 is opened, and the two circulation pumps 61 drive the refrigerant and the cooling agent to flow respectively. Then, the refrigerant absorbs heat and rises in temperature in the evaporator 4 to achieve the purpose of refrigeration. At the same time, the refrigerant exchanges heat with the heat transfer fluid in the heat exchanger 3, reducing the temperature of the heat transfer fluid. The heat transfer fluid absorbs heat and rises in temperature in the evaporator 4, also achieving the purpose of refrigeration. This enables the dual systems to refrigerate together, further accelerating the refrigeration speed. Under the action of the one-way valve 5, the refrigerant in the refrigeration outlet 11 will not flow to the heat transfer mechanism 1.

[0052] In the initial stage of the dual refrigeration system operation, the air-cooling mechanism 2 is used to perform direct expansion air cooling and secondary cooling on the cold storage to quickly lower the temperature inside the cold storage. When the temperature inside the cold storage reaches the specified value, the secondary cooling mechanism 1 is switched to perform secondary cooling on the cold storage to maintain the temperature inside the cold storage.

[0053] When the cooling unit 1 needs to be defrosted, the air-cooled unit 2 is replaced to refrigerate the cold storage, causing the cooling unit 1 to stop and the frost on it to melt automatically. After all the frost has melted, the cooling unit 1 is replaced back to refrigerate, which can save the process of manual defrosting.

[0054] Example 3

[0055] This embodiment discloses a dual-pipe evaporator, which is applied to the intelligent dual refrigeration system described in Embodiment 1 or Embodiment 2. It includes a rectangular mounting frame 41, which is welded from four metal plates. Two circulation pipes 42 are installed inside the mounting frame 41. The circulation pipes 42 are arranged in a serpentine pattern, and both ends of the circulation pipes 42 extend out of the mounting frame 41.

[0056] Two sets of fins 43 are welded onto the mounting frame 41, and two circulation pipes 42 are located between the two sets of fins 43.

[0057] In summary, this invention, by setting up a cooling mechanism 1 and an air-cooling mechanism 2, enables the separate use of two mechanisms to refrigerate the cold storage. Initially, the air-cooling mechanism 2 can be used for rapid cooling, quickly reaching the designated temperature. Then, the cooling mechanism 1 switches to refrigeration to maintain the temperature, thereby reducing energy consumption and noise, and minimizing moisture loss from the food surface. When a thick layer of frost forms on the cooling mechanism 1, the air-cooling mechanism 2 can be switched on, stopping the cooling mechanism 1. After the frost melts, the cooling mechanism 1 can be switched back on, eliminating the need for manual defrosting. By connecting the circulation loop 22 to the refrigeration outlet 11, the refrigerant flowing back from the circulation loop 22 can flow into the heat exchanger 3, allowing the refrigerant to exchange heat with the cooling agent, achieving simultaneous cooling by both the cooling mechanism and the air-cooling, further accelerating the cooling speed. By installing two circulation pipes 42 within the mounting frame 41, the evaporator 4 can simultaneously meet the cooling requirements of the cooling mechanism 1 and the air-cooling mechanism 2, i.e., direct cooling and indirect cooling.
