[0048] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in sequences other than those illustrated or described herein.

[0049] Figure 1 This is a connection diagram of a first type of indirect heat pump system provided according to an embodiment of the present invention, as shown below. Figure 1 As shown, the indirect heat pump system includes:

[0050] Temperature medium output module 1, air conditioning module 2, battery heat exchange module 3, radiator 4, first three-way valve 5 and first five-way valve 6;

[0051] The first output terminal a0 of the temperature medium output module 1 is connected to the first input terminal 51 of the first three-way valve 5, the third input terminal 63 of the first five-way valve 6 is connected to the second input terminal 52 of the first three-way valve 5, and the fourth input terminal 64 of the first five-way valve 6 is connected to the input terminal of the radiator 4; the output terminal of the radiator 4 is connected to the first input terminal a1 of the temperature medium output module 1.

[0052] The second output terminal b0 of the temperature medium output module 1 is connected to the first input terminal 61 of the first five-way valve 6, the second input terminal 62 of the first five-way valve 6 is connected to the input terminal of the battery heat exchange module 3, and the output terminal of the battery heat exchange module 3 is connected to the second input terminal b1 of the temperature medium output module 1.

[0053] The third output terminal c0 of the temperature medium output module 1 is connected to the first input terminal e0 of the air conditioning module 2, and the first output terminal e1 of the air conditioning module 2 is connected to the third input terminal c1 of the temperature medium output module 1.

[0054] The second input terminal f0 of the air conditioning module 2 is connected to the third input terminal 53 of the first three-way valve 5, and the second output terminal f1 of the air conditioning module 2 is connected to the first input terminal a1 of the temperature medium output module 1.

[0055] Air conditioning module 2 includes a cooling core 21 and a heating core 22;

[0056] The cooling core 21 includes a first input terminal e0 and a first output terminal e1 of the air conditioning module 2; the heating core 22 includes a second input terminal f0 and a second output terminal f1 of the air conditioning module 2.

[0057] The temperature medium output module 1 may include a refrigerant, which may be a combustible refrigerant, a toxic refrigerant, or a mixed refrigerant with a large temperature glide value. This refrigerant circulates and exchanges heat within the temperature medium output module 1. The temperature medium output module 1 includes a first output terminal a0, a first input terminal a1, a second output terminal b0, a second input terminal b1, a third output terminal c0, and a third input terminal c1. The first output terminal a0, the second output terminal b0, and the third output terminal c0 can be used to output the heat exchange medium, while the first input terminal a1, the second input terminal b1, and the third input terminal c1 can be used to input the heat exchange medium. This heat exchange medium can exchange heat with the refrigerant in the temperature medium output module 1, thus outputting the temperature from the temperature medium output module 1. In some embodiments, the heat exchange medium may be water.

[0058] The air conditioning module 2 can be used to output heat or cold to the outside. The air conditioning module 2 includes a cold core 21 and a warm core 22. The cold core 21 can be used to output cold, and the warm core 22 can be used to output heat. The third output terminal c0 of the temperature medium output module 1 is connected to the first input terminal e0 of the air conditioning module 2, and the first output terminal e1 of the air conditioning module 2 is connected to the third input terminal c1 of the temperature medium output module 1, forming a flow loop for the heat exchange medium. This allows the heat exchange medium to exchange heat with the refrigerant in the temperature medium output module 1. The heat exchange medium inputs the cooling capacity into the cold core 21, and the cold core 21 discharges the cooling capacity to cool the outside environment. The first output terminal a0 of the temperature medium output module 1 is connected to the first input terminal 51 of the first three-way valve 5, the second input terminal f0 of the air conditioning module 2 is connected to the third input terminal 53 of the first three-way valve 5, and the second output terminal f1 of the air conditioning module 2 is connected to the first input terminal a1 of the temperature medium output module 1. This allows the heat exchange medium to exchange heat with the refrigerant in the first output terminal a0 of the temperature medium output module 1. The heat exchange medium transfers the heat to the heating core 22, and the heating core 22 discharges the heat to heat the outside environment.

[0059] In addition, by connecting the first output terminal a0 of the temperature medium output module 1 to the first input terminal 51 of the first three-way valve 5, the third input terminal 63 of the first five-way valve 6 to the second input terminal 52 of the first three-way valve 5, the fourth input terminal 64 of the first five-way valve 6 to the input terminal of the radiator 4, and the output terminal of the radiator 4 to the first input terminal a1 of the temperature medium output module 1, the heat in the temperature medium output module 1 can be discharged through the radiator 4 in the cooling mode.

[0060] In addition, in this embodiment of the invention, the second output terminal b0 of the temperature medium output module 1 is connected to the first input terminal 61 of the first five-way valve 6, the second input terminal 62 of the first five-way valve 6 is connected to the input terminal of the battery heat exchange module 3, and the output terminal of the battery heat exchange module 3 is connected to the second input terminal b1 of the temperature medium output module 1, forming a flow loop for the heat exchange medium. The heat exchange medium exchanges heat with the refrigerant in the temperature medium output module 1, and delivers the cooling energy to the battery heat exchange module 3 to cool the battery heat exchange module 3 and improve the working reliability of the battery.

[0061] Specifically, Figure 2 This is a connection diagram of a second indirect heat pump system provided according to an embodiment of the present invention, combined with... Figure 1 and Figure 2 As shown, in the dual cooling mode, the refrigerant in the temperature medium output module 1 exchanges heat with the heat exchange medium. The heat exchange medium outputs its cooling capacity to the battery heat exchange module 3 via the second output terminal b0 to cool the battery heat exchange module 3. The heat exchange medium flowing through the battery heat exchange module 3 is then input back to the temperature medium output module 1 via the second input terminal b1 to exchange heat with the refrigerant again, achieving cyclic cooling of the battery. Simultaneously, the refrigerant in the temperature medium output module 1 exchanges heat with the heat exchange medium. The heat exchange medium outputs its cooling capacity to the cold core 21 via the third output terminal c0 to cool the outside environment. The heat exchange medium flowing through the cold core 21 is then input back to the temperature medium output module 1 via the third input terminal c1 to exchange heat with the refrigerant again, achieving cyclic cooling within the cabin. Simultaneously, the refrigerant in the temperature medium output module 1 exchanges heat with the heat exchange medium. The heat exchange medium outputs its heat to the radiator 4 via the first output terminal a0, ensuring the normal operation of the dual cooling mode.

[0062] In the first heating mode, the refrigerant in the temperature medium output module 1 exchanges heat with the heat exchange medium. The heat exchange medium outputs heat to the heating core 22 through the first output terminal a0 to heat the outside. The heat exchange medium flowing through the heating core 22 is then input to the temperature medium output module 1 through the first input terminal a1 to exchange heat with the refrigerant again, so as to realize the cabin circulation heating.

[0063] It is understood that different operating modes can be switched according to the conduction status of the first three-way valve 5 and the first five-way valve 6. This embodiment of the invention only illustrates the operating mode of the dual cooling mode and the first heating mode. This embodiment of the invention does not specifically limit other operating modes.

[0064] In some embodiments, the temperature medium output module 1 is located outside the cabin, and the air conditioning module 2 is located inside the cabin. The cabin interior can be a user distribution area, while the exterior can be an area without users. Placing the temperature medium output module 1 outside the cabin avoids direct contact between the refrigerant and users, effectively preventing the leakage of flammable or toxic refrigerant from harming users inside the cabin. It also effectively solves the temperature slippage problem of non-azeotropic refrigerant mixtures. This arrangement allows for unrestricted use of any type of refrigerant. In some embodiments, this indirect heat pump system can be applied in vehicles, where the cabin interior can be a passenger compartment, improving safety during vehicle use.

[0065] The technical solution of this invention, by setting a cold core and a warm core in the air conditioning module and connecting the cold core and the warm core to the temperature medium output module respectively, allows the cooling and heating in the temperature medium output module to be transferred to the cold core and the warm core respectively through the heat exchange medium, thereby achieving the purpose of cooling or heating. This arrangement isolates the refrigerant in the temperature medium output module from the air conditioning module, preventing the refrigerant from directly participating in the regulation of air temperature, expanding the application range of the refrigerant and ensuring the function of the heat pump system. It can also effectively solve the temperature slip problem of non-azeotropic mixed refrigerants.

[0066] Optional, continue to refer to Figure 1 and Figure 2 As shown, the indirect heat pump system also includes a second five-way valve 7;

[0067] The output end of the radiator 4 is connected to the second input end 72 of the second five-way valve 7, and the first input end 71 of the second five-way valve 7 is connected to the first input end a1 of the temperature medium output module 1.

[0068] The second five-way valve 7 is located between the output end of the battery heat exchange module 3 and the second input end b1 of the temperature medium output module 1. The fourth input end 74 of the second five-way valve 7 is connected to the output end of the battery heat exchange module 3, and the third input end 73 of the second five-way valve 7 is connected to the second input end b1 of the temperature medium output module 1. The third input end 73 of the second five-way valve 7 is connected to the third input end c1 of the temperature medium output module 1.

[0069] The fifth input terminal 75 of the second five-way valve 7 is connected to the input terminal of the battery heat exchange module 3.

[0070] The first output terminal a0 of the temperature medium output module 1 is connected to the first input terminal 51 of the first three-way valve 5, the third input terminal 63 of the first five-way valve 6 is connected to the second input terminal 52 of the first three-way valve 5, the fourth input terminal 64 of the first five-way valve 6 is connected to the input terminal of the radiator 4, the output terminal of the radiator 4 is connected to the second input terminal 72 of the second five-way valve 7, and the first input terminal 71 of the second five-way valve 7 is connected to the first input terminal a1 of the temperature medium output module 1, forming a flow loop for the heat exchange medium. This allows the heat in the heat exchange medium to flow back into the temperature medium output module 1 from the first input terminal a1 after the heat is discharged from the radiator 4, thus realizing the heat dissipation cycle of the heat exchange medium.

[0071] In some embodiments, the indirect heat pump system further includes a motor 8; the motor 8 is disposed between the output end of the radiator 4 and the second input end 72 of the second five-way valve 7; the fifth input end 65 of the first five-way valve 6 is connected to the motor 8. The motor 8 can be a vehicle motor 8, and by distributing the motor 8 between the output end of the radiator 4 and the second input end 72 of the second five-way valve 7, a heat exchange medium can be used to dissipate heat from the motor 8. It is understood that the connection between the motor 8 and the output end of the radiator 4 and the fifth input end 65 of the first five-way valve 6 can be determined according to the operating mode of the indirect heat pump system, as long as heat dissipation of the motor 8 is achieved.

[0072] Optional, continue to refer to Figure 1 and Figure 2 As shown, the indirect heat pump system also includes a second three-way valve 9;

[0073] The second three-way valve 9 is located between the third output terminal c0 of the temperature medium output module 1 and the first input terminal e0 of the air conditioning module 2; the third output terminal c0 of the temperature medium output module 1 is connected to the first input terminal 91 of the second three-way valve 9, the first input terminal e0 of the air conditioning module 2 is connected to the third input terminal 53 of the second three-way valve 9, and the second input terminal 92 of the second three-way valve 9 is connected to the first input terminal 61 of the first five-way valve 6.

[0074] The first input terminal 91 and the third input terminal 93 of the second three-way valve 9 can be connected to allow the heat exchange medium to be input into the cold core 21, and the first input terminal 91 and the second input terminal 92 of the second three-way valve 9 can be connected to allow the heat exchange medium to be input into the first five-way valve 6.

[0075] For example, Figure 3 This is a connection diagram of a third type of indirect heat pump system provided according to an embodiment of the present invention, combined with... Figure 1 and Figure 3As shown, in SuperCharge mode, the first input terminal 51 of the first three-way valve 5 and the third input terminal 63 of the first five-way valve 6 are connected; the third input terminal 63 of the first five-way valve 6 and the fourth output terminal 64 are connected; the third input terminal 73 of the second five-way valve 7 and the fourth input terminal 74 are connected; and the first input terminal 91 and the second input terminal 92 of the second three-way valve 9 are connected. Because the battery in the battery heat exchange module 3 has a high operating efficiency and high heat dissipation requirements in SuperCharge mode, the heat exchange medium in the second output terminal b0 and the third output terminal c0 of the temperature medium output module 1 is output to the battery heat exchange module 3 to improve the heat dissipation efficiency of the battery heat exchange module 3. Simultaneously, the first output terminal a0 of the temperature medium output module 1 inputs the heat from the heat exchange medium to the radiator 4 for discharge, thus achieving heat dissipation for the battery heat exchange module 3.

[0076] For example, Figure 4 This is a connection diagram of a fourth indirect heat pump system provided according to an embodiment of the present invention, combined with... Figure 1 and Figure 4 As shown, in the first heating mode, the first input terminal 51 and the third input terminal 53 of the first three-way valve 5 are connected; the first input terminal 61 and the fourth output terminal 64 of the first five-way valve 6 are connected; the second input terminal 72 and the third input terminal 73 of the second five-way valve 7 are connected; the fourth input terminal 74 and the fifth input terminal 75 of the second five-way valve 7 are connected; the fourth input terminal 74 and the first input terminal 71 of the second five-way valve 7 are connected; and the first input terminal 91 and the second input terminal 92 of the second three-way valve 9 are connected. In the first heating mode, the heat exchange medium at the first output terminal a0 of the temperature medium output module 1 outputs heat to the heating core 22 and the battery heat exchange module 3 to achieve heating. At the same time, the heat exchange medium at the second output terminal b0 and the third output terminal c0 of the temperature medium output module 1 circulates through the first five-way valve 6 and the second five-way valve 7, and this circulated heat exchange medium passes through the radiator 4.

[0077] For example, Figure 5 This is a connection diagram of the fifth indirect heat pump system provided according to an embodiment of the present invention, combined with... Figure 1 and Figure 5As shown, in the second heating mode, the first input terminal 51 and the third input terminal 53 of the first three-way valve 5 are connected; the first input terminal 61 and the fourth output terminal 64 of the first five-way valve 6 are connected; the second input terminal 72 and the third input terminal 73 of the second five-way valve 7 are connected; the fourth input terminal 74 and the fifth input terminal 75 of the second five-way valve 7 are connected; and the first input terminal 91 and the second input terminal 92 of the second three-way valve 9 are connected. In the first heating mode, the heat exchange medium at the first output terminal a0 of the temperature medium output module 1 outputs heat to the heating core 22 and the battery heat exchange module 3 to achieve heating. At the same time, the heat exchange medium at the second output terminal b0 and the third output terminal c0 of the temperature medium output module 1 circulates through the first five-way valve 6 and the second five-way valve 7, and this circulated heat exchange medium does not pass through the radiator 4.

[0078] For example, Figure 6 This is a connection diagram of the sixth indirect heat pump system provided according to an embodiment of the present invention, combined with... Figure 1 and Figure 6 As shown, in dehumidification mode, the second input terminal 52 and the third input terminal 53 of the first three-way valve 5 are connected, the first input terminal 61 and the fourth output terminal 64 of the first five-way valve 6 are connected, the second input terminal 72 and the third input terminal 73 of the second five-way valve 7 are connected, the fourth input terminal 74 and the fifth input terminal 75 of the second five-way valve 7 are connected, and the first input terminal 91 and the third input terminal 93 of the second three-way valve 9 are connected. In dehumidification mode, the heat exchange medium in the temperature medium output module 1 circulates through the second output terminal b0 - the first five-way valve 6 - the radiator 4 - the second five-way valve 7 - the second input terminal b0; the heat exchange medium in the temperature medium output module 1 achieves cooling output through the third output terminal c0 - the cold core 21 - the third input terminal c1; the heat exchange medium in the temperature medium output module 1 achieves heat output through the first output terminal a0 - the first three-way valve 5 - the warm core 22 - the first input terminal a0, thus realizing dehumidification mode.

[0079] The technical solution of this invention, by setting a second three-way valve and a second five-way valve, and by setting different conduction methods, realizes the switching of working modes, thereby ensuring the normal operation of the indirect heat pump system.

[0080] Optional, continue to refer to Figure 2 As shown, the indirect heat pump system also includes a first water pump 111;

[0081] The first water pump 111 is located between the first input terminal 71 of the second five-way valve 7 and the first input terminal a1 of the temperature medium output module 1.

[0082] The first water pump 111 is used to control the circulation of heat exchange medium between temperature medium output module 1, radiator 4 and temperature medium output module 1, so as to achieve efficient circulation of heat exchange medium.

[0083] Optionally, the temperature medium output module 1 includes a cooler 11, a compressor 12, a liquid receiver dryer 13, a first evaporator 14, a second evaporator 15, a first expansion valve 16, and a second expansion valve 17.

[0084] Cooler 11 is connected to compressor 12 and liquid receiver dryer 13 respectively; first evaporator 14 is connected to compressor 12 and liquid receiver dryer 13 respectively; second evaporator 15 is connected to compressor 12 and liquid receiver dryer 13 respectively.

[0085] The first expansion valve 16 is installed on the connecting pipe between the liquid storage dryer 13 and the first evaporator 14, and the second expansion valve 17 is installed on the connecting pipe between the liquid storage dryer 13 and the second evaporator 15.

[0089] The cooling unit 11 condenses the high-temperature, high-pressure gaseous refrigerant output from the compressor 12 into a high-temperature, high-pressure liquid refrigerant. The compressor 12 performs high-temperature, high-pressure processing on the refrigerant. The liquid desiccant absorbs and stores moisture in the refrigerant. The first evaporator 14 and the second evaporator 15 absorb heat from the heat exchange medium, converting the liquid refrigerant into a gaseous refrigerant. The first expansion valve 16 and the second expansion valve 17 reduce the refrigerant pressure and adjust the refrigerant flow rate.

[0090] Specifically, the cooler 11 is connected to the compressor 12 and the receiver-dryer 13 respectively, the first evaporator 14 is connected to the compressor 12 and the receiver-dryer 13 respectively, and the second evaporator 15 is connected to the compressor 12 and the receiver-dryer 13 respectively, so that the refrigerant can achieve heat exchange and circulation between the cooler 11, the receiver-dryer 13, the first evaporator 14 and / or the second evaporator 15, the compressor 12 and the cooler 11. The cooling unit 11 includes a first output terminal a0 and a first input terminal a1 of the temperature medium output module 1, so that the heat exchange medium in the cooling unit 11 absorbs heat from the refrigerant and outputs it from the first output terminal a0; the first evaporator 14 includes a second output terminal b0 and a second input terminal b1 of the temperature medium output module 1, so that the refrigerant in the first evaporator 14 absorbs heat from the heat exchange medium and outputs it from the second output terminal b0; the second evaporator 15 includes a third output terminal c0 and a third input terminal c1 of the temperature medium output module 1, so that the refrigerant in the second evaporator 15 absorbs heat from the heat exchange medium and outputs it from the third output terminal c0, thus ensuring the normal operation of the indirect heat pump system.

[0091] Optional, continue to refer to Figure 1 and Figure 2 As shown, the battery heat exchange module 3 includes a heater 31 and a battery 32;

[0092] The heater 31 is connected to the input terminal of the battery heat exchange module 3 and the battery 32, respectively, and the battery 32 is connected to the output terminal of the battery heat exchange module 3.

[0093] The heater 31 is used to heat the battery 32 in low-temperature environments to ensure its normal operation. The heater 31 is connected to both the input terminal of the battery heat exchange module 3 and the battery 32, and the battery 32 is connected to the output terminal of the battery heat exchange module 3. By heating the heat exchange medium, the temperature of the battery 32 is increased, ensuring its operating efficiency.

[0094] Optional, continue to refer to Figure 1 and Figure 2 As shown, the indirect heat pump system also includes a second water pump 112, a third water pump 113, and a fourth water pump 114.

[0095] The second water pump 112 is located between the output end of the battery heat exchange module 3 and the second input end b1 of the temperature medium output module 1.

[0096] The third water pump 113 is installed between the first output terminal e1 of the air conditioning module 2 and the third input terminal c1 of the temperature medium output module 1.

[0097] The fourth water pump 114 is located between the second input terminal 62 of the first five-way valve 6 and the input terminal of the battery heat exchange module 3.

[0098] Among them, the second water pump 112 can be used to control the circulation of the heat exchange medium flowing through the second input terminal b1 of the temperature medium output module 1, the third water pump 113 can be used to control the circulation of the heat exchange medium flowing through the first input terminal e0 of the air conditioning module 2, and the fourth water pump 114 can be used to control the circulation of the heat exchange medium flowing through the battery heat exchange module 3, so as to achieve efficient circulation of the heat exchange medium.

[0099] In some embodiments, the air conditioning module 2 further includes an air heater 23, which serves as an auxiliary heater in the heating mode.

[0100] According to another aspect of the invention, a vehicle is provided, which includes an indirect heat pump system.

[0101] In this indirect heat pump system, the temperature medium output module can be located outside the vehicle's passenger compartment, while only the air conditioning module is located inside. This avoids direct contact between the refrigerant in the temperature medium output module and the user, effectively preventing the leakage of flammable or toxic refrigerant from harming the user inside the compartment. It also effectively solves the temperature slip problem of non-azeotropic refrigerant mixtures. This configuration allows for unrestricted use of refrigerant types. In some embodiments, this indirect heat pump system can be applied in a vehicle, with the passenger compartment serving as the interior, improving safety during vehicle use.

[0102] The specific embodiments described above do not constitute a limitation on the scope of protection of this invention. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this invention should be included within the scope of protection of this invention.
