Description

Technical Field

[0001] The utility model belongs to the technical field of refrigeration equipment, and in particular relates to an integrated system of a vehicle-mounted air conditioner and freezer. Background Art

[0002] Long-distance transport vehicles operate for extended periods, often traveling at night, forcing drivers to live on board. Therefore, installing air conditioners and refrigerators on these vehicles is essential for drivers' well-being. Currently, the typical approach is to purchase the air conditioners and refrigerators separately and then add large-capacity batteries or generators. This results in high investment, complex systems, and a high risk of failure. Utility Model Content

[0003] To solve the above technical problems, the present invention provides an integrated vehicle air-conditioning and refrigerator system, which converts the electrical energy provided by the engine during long-term vehicle operation into cold energy for storage and can be used after the vehicle is turned off, thereby reducing costs.

[0004] In order to achieve the purpose of this utility model, the technical solution adopted by this utility model is:

[0005] An integrated system for a vehicle-mounted air-conditioning freezer includes a refrigeration component and a phase-change cold storage component. The phase-change cold storage component includes a cold storage tank, a Freon pipe, and an antifreeze pipe. The Freon pipe connects the refrigeration component to form a loop. The refrigeration component includes a compressor, a condenser, a drying filter, and an expansion valve connected in sequence by the Freon pipe. The compressor is powered by the vehicle battery. The antifreeze pipe also forms a loop and provides a cold source for the freezer and air conditioner in the cab. The cold storage tank is filled with a phase-change cold storage agent, and the Freon pipe and the antifreeze pipe exchange heat through the cold storage tank.

[0006] The Freon pipeline and the antifreeze liquid pipeline of the utility model are coiled in the cold storage box.

[0007] Preferably, the cold storage box is provided with an inlet and an outlet of a Freon pipeline on one side, and an inlet and an outlet of an antifreeze pipeline on the other side.

[0008] The refrigerator of the present invention is arranged between the front and rear passenger seats of the vehicle, and the air conditioner is arranged below the refrigerator.

[0009] The antifreeze liquid pipeline of the utility model is provided with a low-temperature water pump after leaving the cold storage box.

[0010] The condenser of the utility model is provided with a heat dissipation fan.

[0011] The vehicle battery of the present invention supplies power to the compressor via a voltage monitoring module.

[0012] The Freon pipeline of the utility model is provided with electromagnetic valves at the connection points with the freezer and the air conditioner.

[0013] The beneficial effects of this utility model lie in: using the vehicle battery to directly power the refrigeration assembly, while the long-distance transport vehicle's engine and battery continuously power the compressor, generating a cold source through the refrigeration assembly. This is then supplied to the cold storage tank via a Freon pipe. The phase-change refrigerant in the cold storage tank undergoes a phase change, absorbing heat and storing the cold, thus achieving cold storage while the vehicle is in operation. After the vehicle stops, a water pump uses the antifreeze liquid in the cold storage tank through an antifreeze pipe as cold, continuously releasing it to the freezer and air conditioner for use in temperature regulation. This method significantly saves energy and equipment investment. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to more clearly and in detail illustrate the purpose and technical solution of the utility model, the utility model is further described below through relevant embodiments. The following embodiments are only for the purpose of specifically illustrating the implementation method of the utility model and do not limit the scope of protection of the utility model.

[0017] Example 1

[0018] like Figure 1 As shown, an integrated system of a vehicle-mounted air-conditioning freezer includes a refrigeration component and a phase-change cold storage component. The phase-change cold storage component includes a cold storage tank 2, a Freon pipe 4 and an antifreeze pipe 5. The Freon pipe 4 connects the refrigeration component to form a loop. The refrigeration component includes a compressor 3, a condenser 7, a drying filter 8 and an expansion valve 14 connected in sequence by the Freon pipe 4. The compressor 3 is powered by the vehicle battery 1; the antifreeze pipe 5 also forms a loop and provides a cold source for the freezer 11 and air conditioner 12 in the cab. The cold storage tank 2 is filled with a phase-change refrigerant 6, and the Freon pipe 4 and the antifreeze pipe 5 pass through the cold storage tank 2 for heat exchange.

[0019] The vehicle's battery 1 directly powers the refrigeration unit's compressor 3. The long-distance transport vehicle's engine generates electricity to continuously power the refrigeration unit, which compresses, condenses, dries, and filters the Freon, converting it into a low-temperature Freon liquid. This liquid is then supplied to the cold storage tank 2 via a Freon pipe 4. The refrigeration unit is equipped with an expansion valve 14 to ensure efficient operation and energy savings. The phase-change refrigerant 6 in the cold storage tank 2 transforms from a liquid to a solid upon exposure to cold, storing cold energy. This phase-change refrigerant exchanges heat with the antifreeze in the antifreeze pipe 5, cooling the antifreeze and storing cold while the vehicle is in operation. After the vehicle is turned off, the stored low-temperature antifreeze can be released through the antifreeze pipe 5 as a cold source for use in the freezer 11 and air conditioner 12.

[0020] Example 2

[0021] This embodiment is based on embodiment 1:

[0022] The Freon pipe 4 and the antifreeze liquid pipe 5 are coiled in the cold storage box to form a sandwich structure, which is conducive to sufficient heat exchange in a limited space.

[0024] Example 3

[0025] This embodiment is based on embodiment 1:

[0026] The antifreeze liquid pipeline 5 is provided with a low-temperature water pump 10 after leaving the cold storage tank 2 to drive the antifreeze liquid to flow.

[0027] The condenser 7 is provided with a heat dissipation fan to facilitate rapid heat dissipation.

[0028] Example 4

[0029] This embodiment is based on embodiment 1:

[0030] The refrigerator 11 is disposed between the front and rear passenger seats of the vehicle, and the air conditioner 12 is disposed below the refrigerator 11 .

[0031] The antifreeze liquid pipeline 5 is provided with a solenoid valve 13 at the connection between the freezer 11 and the air conditioner 12. A cold source can be provided to the freezer or the air conditioner separately, saving energy.

[0032] The vehicle battery 1 supplies power to the compressor 3 through the voltage monitoring module. During normal driving or parking, the vehicle battery 1 will maintain a certain voltage to protect the battery so that the vehicle can start normally.

[0033] The compressor of the utility model adopts an electric scroll compressor with a voltage of 12V-144V, the condenser adopts a dual-fan condenser, the drying filter adopts Sanhua RFKH, the expansion valve adopts Sanhua DPF (TS1) 1.3C, the low-temperature water pump adopts MP-10R-MP-120R, and the voltage monitoring module adopts XH-M604 CNC charging module.

While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention.
