[0004] The compressor and condenser are integrated into the car refrigerator, which is placed inside the passenger compartment of the car. The compressor is quite noisy when it is working, which can cause noise disturbance to users. In addition, the fan blows hot air into the passenger compartment through the ventilation holes, causing a significant temperature rise around the ventilation holes. All of these problems result in poor comfort when using the car refrigerator. Summary of the Invention

[0005] The purpose of this invention is to provide a refrigeration system to solve the technical problem of poor comfort in the use of existing vehicle refrigerators.

[0007] Furthermore, the refrigeration system also includes a pressure regulating structure, a first branch, and a second branch; The first branch is connected between the compressor and the condenser. Along the flow direction of the refrigerant in the first branch, the automotive air conditioning evaporator and the pressure regulating structure are sequentially arranged on the first branch. The second branch is connected between the compressor and the condenser, and the vehicle refrigerator evaporator is located on the second branch.

[0008] Furthermore, the first branch is provided with a first expansion valve, and along the flow direction of the refrigerant in the first branch, the first expansion valve, the automotive air conditioning evaporator, and the pressure regulating structure are arranged in sequence; The second branch is equipped with a second expansion valve, and the second expansion valve and the vehicle refrigerator evaporator are arranged in sequence along the flow direction of the refrigerant in the second branch.

[0009] Furthermore, the refrigeration system also includes a battery cooler; the compressor, the condenser, and the battery cooler form a circulation loop.

[0010] Furthermore, the refrigeration system also includes a pressure regulating structure, a first branch, a second branch, a third branch, and a merging path; One end of the first branch and one end of the third branch are respectively connected to the condenser, and the other end of the first branch and the other end of the third branch are respectively connected to one end of the converging path, and the other end of the converging path is connected to the compressor; The automotive air conditioning evaporator is located on the first branch, the battery cooler is located on the third branch, and the voltage regulating structure is located on the converging path; The second branch is connected between the compressor and the condenser, and the vehicle refrigerator evaporator is located on the second branch.

Similarly, when the refrigerant circulates within this loop, the vehicle-mounted refrigerator evaporator generates cooling capacity, enabling the vehicle-mounted refrigerator to refrigerate items. The compressor and condenser of the car air conditioning unit are not located in the car cabin. The evaporator of the car refrigerator achieves cooling by connecting to the car air conditioning unit. This eliminates the need for a compressor and condenser in the car refrigerator located in the car cabin. The absence of a compressor in the evaporator reduces the noise of the car refrigerator.

Detailed Implementation

[0020] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] This invention provides a refrigeration system, a refrigeration system, and a vehicle. Several embodiments are given below to describe the refrigeration system, refrigeration system, and vehicle provided by this invention in detail.

[0022] The refrigeration system provided in this embodiment, such as Figures 1 to 4 As shown, it includes an automotive air conditioning unit, an automotive air conditioning evaporator 4, and a vehicle refrigerator evaporator 2; the automotive air conditioning unit includes a compressor 3 and a condenser 6; the compressor 3, the condenser 6, and the automotive air conditioning evaporator 4 form a circulation loop; the compressor 3, the condenser 6, and the vehicle refrigerator evaporator 2 form a circulation loop.

[0023] The compressor 3, condenser 6 and automotive air conditioning evaporator 4 form a circulation loop. When the refrigerant circulates in this loop, the automotive air conditioning evaporator 4 can generate cooling capacity, thereby providing air conditioning for the car cabin.

[0024] The compressor 3, condenser 6 and vehicle refrigerator evaporator 2 form a circulation loop. When the refrigerant circulates in this loop, the vehicle refrigerator evaporator 2 can generate cooling capacity, enabling the vehicle refrigerator to refrigerate items.

[0025] The compressor 3 and condenser 6 of the car air conditioning unit are not located in the car cabin. The evaporator 2 of the car refrigerator achieves cooling by connecting to the car air conditioning unit. This eliminates the need for compressor 3 and condenser 6 in the car refrigerator located in the car cabin. The absence of compressor 3 in the evaporator 2 of the car refrigerator reduces the noise of the car refrigerator. The absence of condenser 6 in the car refrigerator reduces the amount of hot air blown into the car cabin by the car refrigerator and reduces the temperature rise around the heat dissipation vents of the car refrigerator, thereby improving the comfort of using the car refrigerator.

[0026] Furthermore, the refrigeration system also includes a pressure regulating structure 1, a first branch 12, and a second branch 13; the first branch 12 is connected between the compressor 3 and the condenser 6, and along the flow direction of the refrigerant in the first branch 12, the automotive air conditioning evaporator 4 and the pressure regulating structure 1 are sequentially arranged on the first branch 12; the second branch 13 is connected between the compressor 3 and the condenser 6, and the vehicle refrigerator evaporator 2 is arranged on the second branch 13.

[0027] Specifically, the compressor 3 and the condenser 6 are connected through the first pipeline assembly 7. After being compressed by the compressor 3, the refrigerant enters the condenser 6. The gaseous refrigerant is condensed into liquid refrigerant in the condenser 6. The refrigerant flowing out of the condenser 6 flows into the first branch 12 and the second branch 13 through the air conditioning high-pressure main inlet 11. The refrigerant in the first branch 12 flows into the car air conditioning evaporator 4, and the refrigerant in the second branch 13 flows into the vehicle refrigerator evaporator 2.

[0028] A pressure regulating structure 1 is installed on the first branch 12 to regulate the refrigerant pressure at the outlet of the car air conditioner evaporator 4. Since the load of the car air conditioner evaporator 4 is large and the load of the vehicle refrigerator evaporator 2 is small, the outlet refrigerant pressure of the car air conditioner evaporator 4 is large and the outlet refrigerant pressure of the vehicle refrigerator evaporator 2 is small. By regulating the outlet refrigerant pressure of the car air conditioner evaporator 4 through the pressure regulating structure 1, the outlet refrigerant pressure of the car air conditioner evaporator 4 is reduced so that the outlet refrigerant pressure of the car air conditioner evaporator 4 is close to that of the vehicle refrigerator evaporator 2. This prevents the refrigerant flow in the vehicle refrigerator evaporator 2 from being too small and ensures that the vehicle refrigerator evaporator 2 meets the cooling target requirements.

[0029] After being regulated by the pressure regulating structure 1, the refrigerant flows out of the first branch 12. The refrigerant flowing out of the first branch 12 and the refrigerant flowing out of the second branch 13 merge in the main pipeline and finally flow from the main pipeline to the low-pressure main outlet 10, and then from the low-pressure main outlet 10 to the compressor 3.

[0030] The pressure regulating structure 1 can be a large-diameter electronic expansion valve, or any other suitable type of valve such as a pressure regulating valve. In this embodiment, the pressure regulating structure 1 is a 16mm large-diameter electronic expansion valve.

[0031] Furthermore, the first branch 12 is provided with a first expansion valve, and along the flow direction of the refrigerant in the first branch 12, the first expansion valve, the automotive air conditioning evaporator 4 and the pressure regulating structure 1 are arranged in sequence; the second branch 13 is provided with a second expansion valve, and along the flow direction of the refrigerant in the second branch 13, the second expansion valve and the vehicle refrigerator evaporator 2 are arranged in sequence.

[0032] The compressor 3, condenser 6, first expansion valve and automotive air conditioning evaporator 4 are connected in sequence to form a refrigeration cycle loop. The first expansion valve plays the role of throttling and reducing pressure.

[0033] The compressor 3, condenser 6, second expansion valve and vehicle refrigerator evaporator 2 are connected in sequence to form a refrigeration cycle loop. The second expansion valve plays the role of throttling and reducing pressure.

[0034] Furthermore, the refrigeration system also includes a battery cooler 5; the compressor 3, condenser 6, and battery cooler 5 form a circulation loop.

[0035] The compressor 3, condenser 6 and battery cooler 5 form a circulation loop. When the refrigerant circulates in this loop, the battery cooler 5 can generate cooling energy, thereby cooling the battery.

[0036] Furthermore, the refrigeration system also includes a pressure regulating structure 1, a first branch 12, a second branch 13, a third branch 14, and a confluence path; one end of the first branch 12 and one end of the third branch 14 are respectively connected to the condenser 6, the other end of the first branch 12 and the other end of the third branch 14 are respectively connected to one end of the confluence path, and the other end of the confluence path is connected to the compressor 3; the automotive air conditioning evaporator 4 is installed on the first branch 12, the battery cooler 5 is installed on the third branch 14, and the pressure regulating structure 1 is installed on the confluence path; the second branch 13 is connected between the compressor 3 and the condenser 6, and the vehicle refrigerator evaporator 2 is installed on the second branch 13.

[0037] Specifically, after being compressed by the compressor 3, the refrigerant enters the condenser 6. The gaseous refrigerant is condensed into liquid refrigerant in the condenser 6. The refrigerant flowing out of the condenser 6 flows into the first branch 12, the second branch 13 and the third branch 14 through the air conditioning high-pressure main inlet 11. The refrigerant in the first branch 12 flows into the car air conditioning evaporator 4, the refrigerant in the second branch 13 flows into the car refrigerator evaporator 2, and the refrigerant in the third branch 14 flows into the battery cooler 5.

[0038] The refrigerant flowing from the automotive air conditioning evaporator 4 flows into the confluence path through the first branch 12, and the refrigerant flowing from the battery cooler 5 flows into the confluence path through the third branch 14. The refrigerant flowing from the automotive air conditioning evaporator 4 and the refrigerant flowing from the battery cooler 5 converge in the confluence path. The pressure regulating structure 1 adjusts the refrigerant pressure in the confluence path. Because the automotive air conditioning evaporator 4 and the battery cooler 5 have large loads, while the on-board refrigerator evaporator 2 has a small load, the outlet refrigerant pressure of the automotive air conditioning evaporator 4 is large, the outlet refrigerant pressure of the battery cooler 5 is large, and the outlet refrigerant pressure of the on-board refrigerator evaporator 2 is small. By adjusting the refrigerant pressure in the confluence path through the pressure regulating structure 1, the refrigerant pressure in the confluence path is reduced so that the refrigerant pressure in the confluence path is close to the outlet refrigerant pressure of the on-board refrigerator evaporator 2. This prevents the refrigerant flow in the on-board refrigerator evaporator 2 from being too small and ensures that the on-board refrigerator evaporator 2 meets the cooling target requirements.

[0039] After being regulated by the pressure regulating structure 1, the refrigerant flows out of the confluence path. The refrigerant flowing out of the confluence path merges with the refrigerant flowing out of the second branch 13 in the main pipeline, and finally flows from the main pipeline to the low-pressure main outlet 10, and then from the low-pressure main outlet 10 to the compressor 3.

[0040] The pressure regulating structure 1 can be a large-diameter electronic expansion valve, or any other suitable type of valve such as a pressure regulating valve. In this embodiment, the pressure regulating structure 1 is a 16mm large-diameter electronic expansion valve.

[0041] Furthermore, the first branch 12 is equipped with a first expansion valve, and along the flow direction of the refrigerant in the first branch 12, the first expansion valve and the automotive air conditioning evaporator 4 are arranged in sequence; the second branch 13 is equipped with a second expansion valve, and along the flow direction of the refrigerant in the second branch 13, the second expansion valve and the vehicle refrigerator evaporator 2 are arranged in sequence; the third branch 14 is equipped with a third expansion valve, and along the flow direction of the refrigerant in the third branch 14, the third expansion valve and the battery cooler 5 are arranged in sequence.

[0042] The compressor 3, condenser 6, first expansion valve and automotive air conditioning evaporator 4 are connected in sequence to form a refrigeration cycle loop. The first expansion valve plays the role of throttling and reducing pressure.

[0043] The compressor 3, condenser 6, second expansion valve and vehicle refrigerator evaporator 2 are connected in sequence to form a refrigeration cycle loop. The second expansion valve plays the role of throttling and reducing pressure.

[0044] The compressor 3, condenser 6, first expansion valve and automotive air conditioning evaporator 4 are connected in sequence to form a refrigeration cycle loop. The first expansion valve plays the role of throttling and reducing pressure.

[0045] The compressor 3, condenser 6, third expansion valve and battery cooler 5 are connected in sequence to form a refrigeration cycle loop. The third expansion valve plays the role of throttling and reducing pressure.

[0046] Furthermore, the third branch 14 is also equipped with a pressure and temperature sensor. Along the flow direction of the refrigerant in the third branch 14, the third expansion valve, the battery cooler 5, and the pressure and temperature sensor are arranged in sequence.

[0047] The refrigerant flowing out of the battery cooler 5 on the third branch 14 passes through the pressure and temperature sensor and then flows out of the third branch 14. The refrigerant flowing out of the third branch 14 merges with the refrigerant flowing out of the first branch 12 in the merging path.

[0048] The temperature and pressure values ​​of the refrigerant flowing out of the battery cooler 5 can be detected by the pressure and temperature sensor.

[0049] Furthermore, a pressure sensor 8 is provided on the outlet side of the condenser 6.

[0050] The refrigerant flowing out of the outlet of the condenser 6 flows through the pressure sensor 8 and into the first branch 12, the second branch 13 and the third branch 14 respectively through the air conditioning high-pressure main inlet 11.

[0051] The refrigerant pressure at the outlet of the condenser 6 can be detected by pressure sensor 8.

[0052] Furthermore, a temperature sensor 9 is provided on the inlet side of the compressor 3.

[0053] The refrigerant that reaches the outlet of the main compressor flows to the temperature sensor 9, and after passing through the temperature sensor 9, it flows into the compressor 3.

[0054] Temperature sensor 9 can detect the temperature of the refrigerant flowing into compressor 3 and can control and monitor the refrigerant flowing into compressor 3 within a suitable temperature range.

[0055] The vehicle provided in this embodiment includes the refrigeration system provided in this embodiment. The compressor 3 and condenser 6 of the automotive air conditioning unit are not located in the vehicle cabin. The evaporator 2 of the vehicle refrigerator achieves refrigeration by connecting to the automotive air conditioning unit. This eliminates the need for a compressor 3 and condenser 6 in the vehicle refrigerator located in the vehicle cabin. The absence of a compressor 3 in the vehicle refrigerator evaporator 2 reduces the noise of the vehicle refrigerator. The absence of a condenser 6 also reduces the amount of hot air blown into the vehicle cabin by the vehicle refrigerator and reduces the temperature rise around the heat dissipation vents of the vehicle refrigerator, thereby improving the comfort of using the vehicle refrigerator.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
