On the basis of the above structure, the air-conditioning box module 14 further includes a second air-conditioning box module 39, the second air-conditioning box module 39 includes a second air-conditioning box housing 34, an air inlet of the second air-conditioning box housing 34 is connected to another air outlet of the air inlet housing 6, and along the air flow direction, a second air blower 38, a second cold air core 37, a second temperature air door 36 and a second warm air core 35 are sequentially arranged in the second air-conditioning box housing 34. The air distribution module 16 further comprises a second air distribution submodule 32, the second air distribution submodule 32 comprises a second air distribution shell 31, an air inlet of the second air distribution shell 31 is connected to an air outlet of a second air conditioner shell 34, a second face blowing air port 25, a second foot blowing air port 27 and a second defrosting air port 29 which are independent of each other are arranged on the second air distribution shell 31, a second face blowing air door 26 used for controlling the opening and the closing of the second face blowing air port 25 is arranged on the second face blowing air port 25, a second foot blowing air door 28 used for controlling the opening and the closing of the second foot blowing air port 27 is arranged on the second foot blowing air port 27, and a second defrosting air door 30 used for controlling the opening and the closing of the second defrosting air port 29 is arranged on the second defrosting air port.

In the distributed air conditioning assembly, the first air blower 8 and the second air blower 38 are used as power sources to suck air from the air inlet module 1, push the air to flow in the air conditioning box module 14 and discharge the air from the air distribution module 16. The air inlet housing 6 forms an air inlet channel, and the fresh air/circulating air door 3 opens/closes the fresh air port 2 or the circulating air port 4 through translation or rotation, so that the air inlet source and the ratio flowing into the air inlet module 1 are controlled. The intake air is purified by the filter 5 along the intake flow path and then divided into one or more flows into the corresponding air conditioning box modules.

As shown in fig. 1, the airflow into the air conditioning box module 14 is branched into two branches: the first air conditioning box module 13 and the first air distribution submodule 24 form a first branch, and the second air conditioning box module 39 and the second air distribution submodule 32 form a second branch. The air inlet module 1 is connected with the first air conditioning box module 13 at a first air conditioning box air inlet 7, and the air inlet module 1 is connected with the second air conditioning box module 39 at a second air conditioning box air inlet 40. In the first branch, a first air-conditioning box shell 12 forms a first air-conditioning box internal flow passage; the amount of air flowing through the first branch can be adjusted by changing the rotational speed of the first blower 8. The air flow discharged from the first air blower 8 enters the first cold air core 9 completely and radiates heat to the low-temperature intermediate medium in the core, so that the temperature and the humidity of the inlet air are reduced, and then the inlet air flows through the first temperature damper 10. The first temperature damper 10 guides a part of low temperature air flow into the first warm air core 11 by changing the position according to the control signal and absorbs heat from the high temperature intermediate medium in the core; thereby causing the temperature of this portion of the gas stream to rise. Then, the middle temperature air flow is mixed with the low temperature intake air bypassed by the first temperature damper 10, adjusted to the required temperature and humidity, and then flows into the first air distribution submodule 24.

The first air conditioning box module 13 is connected to the first air distribution submodule 24 at a first air conditioning box-air distribution submodule interface 15. The air flow with the set temperature and humidity flows out of the first face air blowing opening 19, the first foot air blowing opening 21 and the first defrosting opening 23 along the first air distribution flow channel formed by the first air distribution shell 17. The first face damper 18, the first foot damper 20 and the first defroster damper 22 respectively control the flow rate of the air flowing out from the above-mentioned ports by adjusting the respective damper positions.

Similarly, in the second branch: the second air-conditioning box housing 34 forms a second air-conditioning box internal flow passage; the amount of air flowing through the second branch can be adjusted by varying the speed of the second blower 38. The air flow from the second air blower 38 enters the second cool air core 37 entirely and radiates heat to the low temperature intermediate medium in the core, so that the temperature and humidity of the intake air are reduced and then flows through the second temperature damper 36. The second temperature damper 36, by changing its position according to the control signal, guides a part of the low temperature air flow into the second warm air core 35 and absorbs heat from the high temperature intermediate medium in the core; thereby causing the temperature of this portion of the gas stream to rise. The intermediate temperature air flow is then mixed with the low temperature intake air bypassed by the second temperature damper 36, adjusted to the desired temperature and humidity, and then flows into the second air distribution sub-module 32. The second air conditioning box module 39 is connected to the second air distribution submodule 32 at a second air conditioning box-air distribution submodule interface 33. The temperature and humidity-adjusted air flows out of the second face blowing air opening 25, the second foot blowing air opening 27 and the second defrosting air opening 29 along a second air distribution flow passage formed by the second air distribution casing 31. The second face damper 26, the second foot damper 28, and the second defroster damper 30 respectively control the flow rate of the air flowing out from the above-described ports by adjusting the respective damper positions.

The distributed air conditioning assembly can form the configuration of multiple temperature partitions and multiple mode control of the passenger compartment in a modular splicing mode, so that the requirements of different vehicle types on the functions and the arrangement of an air conditioning system are met.

The air conditioning box module 14 comprises a first air conditioning box module 13 and a second air conditioning box module 39, and the air distribution module 16 comprises a first air distribution submodule 24 and a second air distribution submodule 32. The environment fresh air of the vehicle head or the return air at the front part in the vehicle enters the air-conditioning assembly from the air inlet module 1 and is then divided into two paths, one path of air passes through the first air-conditioning box module 13 and the first air distribution sub-module 24 in sequence to supply air for the main driving seat 44 and the peripheral area thereof; the other path of air passes through the second air conditioning box module 39 and the second air distribution sub-module 32 in sequence to supply air to the assistant driver seat 45 and the peripheral area thereof. The first air conditioning box module 13 and the second air conditioning box module 39 independently adjust the air quantity, the temperature and the humidity of air flowing through by means of a fan, a heat exchange core body and a temperature air door in the modules according to the requirements of passengers; the first air distribution submodule 24 and the second air distribution submodule 32 independently adjust the air supply mode through an internal air door according to the requirement of passengers; therefore, the air conditioning function of double temperature zones and independent modes, which can independently adjust the temperature/humidity of air supply, the air quantity and the mode of main driving and auxiliary driving, is realized on the whole vehicle.

An air conditioning assembly configuration providing single temperature zone control for a passenger compartment is shown in fig. 4 and 5. The arrangement mode is similar to that of the dual-temperature-zone air conditioner, but the air conditioning box module 14 only comprises a first air conditioning box module 13, and the air distribution module 16 only comprises one or two air distribution sub-modules, in the embodiment, the air distribution module 16 comprises a first air distribution sub-module 24 and a second air distribution sub-module 32; therefore, the air supply temperature/humidity and the air volume of the main driving seat 44 and the auxiliary driving seat 45 can not be independently adjusted, and the mode can realize the single-temperature-zone air conditioning function of non-independent or independent adjustment according to the configuration.

An air conditioning assembly configuration providing four temperature zone control for a passenger compartment is shown in fig. 6 and 7. The arrangement mode of the air conditioning assemblies of the front cabin and the front row is the same as that of the double-temperature-zone air conditioner, and meanwhile, a set of independent air conditioning assembly is additionally arranged at the tail part of the vehicle body and comprises a rear air inlet module 49, a rear air conditioning box module 48 and a rear air distribution module 47. The rear air conditioning box module 48 comprises a first rear air conditioning box module 51 and a second rear air conditioning box module 53, and the rear air distribution module 47 comprises a first rear air distribution submodule 50 and a second rear air distribution submodule 52. The environment fresh air at the rear part of the vehicle body or the return air at the rear part in the vehicle enters the air conditioner assembly from the rear air inlet module 49, and then is divided into two paths, wherein one path of air is supplied to the left seat of the rear-row seat 46 and the peripheral area thereof through the first rear air conditioning box module 51 and the first rear air distribution sub-module 50 in sequence; the other path passes through the second rear air conditioning box module 53 and the second rear air distribution sub-module 52 in sequence to supply air to the peripheral area of the right seat of the rear seat 46. The first rear air-conditioning box module 51 and the second rear air-conditioning box module 53 independently adjust the air quantity, temperature and humidity of air flowing through the modules according to the requirements of passengers by means of a fan, a heat exchange core and a temperature air door in the modules; the first rear air distribution submodule 50 and the second rear air distribution submodule 52 independently adjust the air supply mode by means of an internal air door according to the requirements of passengers; therefore, the air conditioning function of four temperature zones and independent modes, wherein the air supply temperature/humidity, the air quantity and the mode of the front row of main driving and auxiliary driving and the rear row of left seats and right seats can be independently adjusted, is realized on the whole vehicle.

An air conditioning assembly configuration providing three temperature zone control for a passenger compartment is shown in fig. 8 and 9. The arrangement mode is similar to that of a four-temperature-zone air conditioner, but the rear air conditioning box module 48 only comprises one air conditioning box module, and the rear air distribution module 47 can comprise one or two air distribution sub-modules; thus, the air supply temperature/humidity and the air volume of the left and right seats of the rear seat 46 can not be independently adjusted, and the mode can realize the function of non-independent or independent adjustment according to the configuration. And is combined with the configuration of a front row of dual-temperature-zone air-conditioning assembly; therefore, the air conditioning function of three temperature zones and independent modes, wherein the temperature/humidity, the air quantity and the mode of the air supply of the main driving, the auxiliary driving and the rear row can be independently adjusted, is realized on the whole vehicle.

The air conditioning assembly and the air conditioning system can carry out completely independent zone control on parameters such as temperature/humidity, air quantity, modes and the like of the passenger compartment according to the actual passenger carrying condition, thereby meeting the individual requirements of energy conservation and environmental comfort of the whole vehicle.

The refrigerant of the indirect heat pump air conditioning system circulates among the components and refrigerant lines of the heating and cooling module 57. According to the system requirement, the refrigerant can be selected from conventional refrigerants such as R134a, R1234yf, R407c, R410a and the like, high-performance and high-environmental-protection refrigerants such as R290, R744 and the like, and other phase-change refrigerants capable of meeting the requirement.

The intermediate medium of the indirect heat pump air conditioning system circulates in the front end cooling module 54, the heating and cooling module 57, the water pump valve group module 73, the parts of the air conditioning box module 14 and the intermediate medium pipeline. According to the system requirement, the intermediate medium can be selected from but not limited to pure water, a mixture of water and alcohols such as glycol or glycerol, water and inorganic salt solution, alcohol, oil and other liquid media.

In the indirect heat pump air conditioning system, three intermediate medium interfaces are arranged on the valve bodies of the liquid inlet three-way valve 62 and the liquid return three-way valve 67, and are numbered from a to c in sequence. Liquid inlet three-way valve 62 and liquid return three-way valve 67 all have three mode: in the mode 1, the intermediate medium interfaces a-c are communicated, and other interfaces are not communicated; in the mode 2, the intermediate medium interfaces b-c are communicated, and the other interfaces are not communicated; in mode 3, the intermediate medium interfaces are not connected. The intermediate medium inlet 62-a of the liquid inlet three-way valve 62 is connected with the cold side liquid inlet three-way valve 78, the intermediate medium inlet 62-b is connected with the hot side liquid inlet three-way valve 64, and the intermediate medium outlet 62-c is connected with the flow regulating valve 77.

The first mode adjustment valve 72 and the second mode adjustment valve 71 are used to control the flow direction of the intermediate medium, thereby realizing different system operation modes. As shown in fig. 11, the mode regulating valve is preferably of an integrated design, including a valve body 80, a valve spool 81 and an intermediate medium port 82. Eight intermediate medium interfaces 82 are arranged on the valve body 80 and are numbered as a-h in sequence; the valve body 81 is provided with a specially designed internal flow passage for communicating with a designated intermediate medium port 82 in each mode. Different medium interface communication modes can be realized by rotating the valve core 81 to different positions, so that the flow direction of a medium is changed, and different system operation modes are realized.

As shown in fig. 12, the mode regulating valve has five typical operation modes according to the position of the valve core 81: in the mode 1, the valve core 81 is in the middle position, a-h, b-c, d-e and g-f of the middle medium interface 82 are respectively communicated, and other interfaces are not communicated; in the mode 2, the valve core 81 rotates clockwise by a certain angle at the position of the mode 1, b-c and g-f of the intermediate medium interface 82 are respectively communicated, and other interfaces are not communicated; in the mode 3, the valve core 81 continuously rotates clockwise for a certain angle at the position of the mode 2, the a-b, the d-e and the g-h of the intermediate medium interface 82 are respectively communicated, and the other interfaces are not communicated; in the mode 4, the valve core 81 rotates counterclockwise by a certain angle at the position of the mode 1, the a-h and the d-e of the intermediate medium interface 82 are communicated, and the other interfaces are not communicated; mode 5: the valve core 81 continues to rotate counterclockwise for a certain angle at the position of the mode 4, b-c, e-f and g-h of the intermediate medium interface 82 are respectively communicated, and other interfaces are not communicated.

Of course, the function of the mode adjustment valve may be realized by a combination of a plurality of two-way valves, three-way valves, or four-way valves.

The mode regulating valve and other parts of the heat pump air conditioning system are connected in the following mode: the interface 72-a of the first mode adjusting valve 72 is connected with the cold-side liquid inlet distribution manifold 75, the interface 72-b is connected with the inlet of the first cold air core 11, the interface 72-c is connected with the hot-side liquid inlet distribution manifold 69, the interface 72-d is connected with the cold-side liquid return distribution manifold 74, the interface 72-e is connected with the outlet of the first cold air core 9, the interface 72-f is connected with the hot-side liquid return distribution manifold 70, the interface 72-g is connected with the outlet of the first cold air core 11, and the interface 72-h is connected with the inlet of the first cold air core 9. The interface 71-a of the second mode adjusting valve 71 is connected with the cold-side liquid inlet distribution manifold 75, the interface 71-b is connected with the inlet of the second warm air core 35, the interface 71-c is connected with the hot-side liquid inlet distribution manifold 69, the interface 71-d is connected with the cold-side liquid return distribution manifold 74, the interface 71-e is connected with the outlet of the second cool air core 37, the interface 71-f is connected with the hot-side liquid return distribution manifold 70, the interface 71-g is connected with the outlet of the second warm air core 35, and the interface 71-h is connected with the inlet of the second cool air core 37.

On the basis of the structure, the cold side liquid inlet distribution multi-way 75 and the hot side liquid inlet distribution multi-way 69 are both of a structure with one inlet and one outlet, and the number of outlet branches is equal to the number of air conditioning sub-modules in the system. The cold-side liquid return distribution manifold 74 and the hot-side liquid return distribution manifold 70 are both of a structure with multiple inlets and multiple outlets, and the number of inlet branches is equal to the number of air conditioning sub-modules in the system. The flow rate regulating valve 77 regulates the flow rate of the intermediate medium flowing through the branch by changing its own path.

A refrigerant circulation route: the compressor 60 draws a low-temperature and low-pressure gaseous refrigerant from an inlet, compresses the refrigerant into a high-temperature and high-pressure gaseous refrigerant, and discharges the refrigerant. The high-temperature and high-pressure gaseous refrigerant flows into the intermediate medium heater 61, and exchanges heat with the intermediate medium with lower temperature in the intermediate medium heater; the refrigerant is exothermically liquefied into a liquid refrigerant with medium temperature and high pressure. The liquid refrigerant then flows into the electronic expansion valve 59 and is throttle expanded to convert it to a two-phase fluid at low temperature and pressure. The refrigerant in the two-phase state then flows into the intermediate medium cooler 58 and exchanges heat with the intermediate medium having a higher temperature in the interior thereof; the refrigerant absorbs heat and is gasified into a medium-temperature low-pressure gaseous refrigerant. The low-temperature and low-pressure gaseous refrigerant finally flows back to the inlet of the compressor 60.

Intermediate medium circulation route: the intermediate medium exchanges heat with the refrigerant in the intermediate medium cooler 58 and is cooled to become a low-temperature intermediate medium; is pumped by a cold side medium pump 79 and is conveyed to a cold side liquid inlet tee 78, and then is divided into two paths: one path flows to the cold side inlet distribution manifold 75 and the other path flows to the inlet three-way valve 62. The intermediate medium exchanges heat with the refrigerant in the intermediate medium heater 61 and is heated to become a high-temperature intermediate medium; is pumped by a hot side medium pump 63, passes through an electric heater 65 and is conveyed to a hot side liquid inlet tee joint 64, and is divided into two paths: one path flows to the hot side inlet liquid distribution manifold 69, and the other path also flows to the inlet liquid three-way valve 62.

The low-temperature intermediate medium is divided into a plurality of branches again through a cold-side liquid inlet distribution manifold 75 and flows into each mode regulating valve respectively; the high-temperature intermediate medium is divided into a plurality of branches again through the hot-side feed liquid distribution manifold 69 and flows into the mode regulating valves respectively. A first branch: the low-temperature intermediate medium flows into the valve body from the 72-a interface of the first mode adjusting valve 72, flows out of the valve body from the 72-d interface and enters the cold-side liquid return distribution multi-way 74; the high-temperature intermediate medium flows into the valve body from the 72-c interface of the first mode adjusting valve 72, flows out of the valve body from the 72-f interface and enters the hot-side return liquid distribution multi-way 70. One path of the intermediate medium entering the valve body flows into the first cold air core 9 through 72-h, exchanges heat with air flowing through the core, and then returns to the first mode regulating valve 72 from a 72-e interface; the other path flows into the first heater core 11 via 72-b, exchanges heat with the air flowing through the core, and then returns to the first mode adjustment valve 72 from the 72-g connection. A second branch circuit: the low-temperature intermediate medium flows into the valve body from the port 71-a of the second mode adjusting valve 71, flows out of the valve body from the port 71-d and enters the cold-side liquid return distribution multi-way 74; the high-temperature intermediate medium flows into the valve body from the 71-c interface of the second mode adjusting valve 71, flows out of the valve body from the 71-f interface and enters the hot-side liquid return distribution multi-way 70. One path of the intermediate medium entering the valve body flows into the second cold air core 37 through 71-h, exchanges heat with air flowing through the core, and then returns to the second mode adjusting valve 71 from a 71-e interface. If there are more branches, the flow of each branch is exactly the same as described above. And each mode regulating valve is in a corresponding working mode according to the control signal, so that the communication mode of the interface is controlled.

The liquid inlet three-way valve 62 is in a corresponding working mode according to the control signal, and selects to allow the high-temperature intermediate medium or the low-temperature intermediate medium to flow into the flow regulating valve 77, and continuously flow into the radiator 55, and perform heat exchange with the surrounding environment therein, and then pass through the expansion kettle 76, remove the entrained gas, and enter the liquid return three-way valve 67. The fan assembly 56 operates in response to the control signal to drive the ambient air through the radiator and exchange heat with the intermediate medium inside the radiator 55. The liquid return three-way valve 67 selects to let the intermediate medium passing through the cooling module 54 enter the hot side liquid return three-way valve 68 or the cold side liquid return three-way valve 66 according to the corresponding working mode of the control signal.

The intermediate medium which enters the cold-side liquid return distribution manifold 74 and has the increased temperature passes through the cold-side liquid return tee 66, is mixed with the intermediate medium flowing back from the liquid return tee 67, and then returns to the intermediate medium cooler 58. The intermediate medium which enters the hot-side liquid return distribution multi-way 70 and has the reduced temperature passes through the hot-side liquid return tee joint 68, is mixed with the intermediate medium flowing back from the liquid return tee joint 67, and then returns to the intermediate medium heater 61.

The indirect heat pump air conditioning system has multiple working modes, and typical system working modes comprise multiple working modes such as a conventional refrigeration mode (single core body), a maximum refrigeration mode (two core bodies are connected in series), a conventional heating mode (single core body), a maximum heating/defrosting mode (two core bodies are connected in series), a refrigeration and dehumidification mode, a heating and dehumidification mode, a demisting mode, a zone control mode (double-temperature zone), a zone control mode (full-cold and full-heat mode) and/or an ice melting mode. By "and/or" is meant that the indirect heat pump air conditioning system may perform one, several, or all of the above described modes of operation, and not necessarily all of the modes of operation.

FIG. 13 illustrates the first mode of operation of the system: conventional refrigeration (single core) mode. The liquid inlet three-way valve 62 and the liquid return three-way valve 67 are both in the mode 2, and the b-c interfaces of the three-way valves are communicated. The first mode adjustment valve 72 and the second mode adjustment valve 71 are both in mode 4; the a-h and d-e interfaces of the mode regulating valve are communicated, so that intermediate media flow through the first cold air core 9 and the second cold air core 37; the b-c and g-f interfaces of the mode adjusting valve are disconnected, so that no intermediate medium flows through the first warm air core 11 and the second warm air core 35.

The low-temperature intermediate medium in the intermediate medium cooler 58 passes through a cold-side medium pump 79 and a cold-side feed tee 78, then enters a cold-side feed distribution manifold 75 and branches, and then flows into the first mode adjusting valve 72 and the second mode adjusting valve 71 respectively. The low-temperature intermediate medium of the first branch flows into the first cold air core 9, cools the inlet air of the first air conditioning box module 13, and then returns to the first mode adjusting valve 72 and enters the cold-side liquid return distribution multi-way 74; the low temperature intermediate medium of the second branch flows into the second cold-air core 37, cools the inlet air of the second air conditioning box module 39, and then returns to the second mode adjustment valve 71 to enter the cold-side return distribution manifold 74. Multiple intermediate mediums are combined in the cold-side return distribution manifold 74 and flow out through the cold-side return tee 66 and back to the intermediate medium cooler 58.

The high-temperature intermediate medium in the intermediate medium heater 61 passes through a hot-side medium pump 63, an electric heater 65 and a hot-side liquid inlet three-way valve 64, and then flows to a liquid inlet three-way valve 62; the electric heater 65 is not operated in this mode. The high-temperature intermediate medium passes through the flow regulating valve 77 at the fully open position, radiates heat to ambient air in the radiator 55, and then passes through the expansion water kettle 76, the liquid return three-way valve 67 and the hot-side liquid return three-way valve 68 in sequence to return to the intermediate medium heater 61. The fan assembly 56 may be turned on as needed to ensure ambient air flow through the radiator 55.

The first temperature damper 10 in the first air conditioning box module 13 and the second temperature damper 36 in the second air conditioning box module 39 are both in the fully closed position; the inlet air respectively passes through the first cold air core 9 and the second cold air core 37 and is cooled, so that the conventional refrigeration function is realized.

Fig. 14 shows the second system operation mode: maximum cooling (two cores in series) mode. The liquid inlet three-way valve 62 and the liquid return three-way valve 67 are both in the mode 2, and the b-c interfaces of the three-way valves are communicated. The first mode adjustment valve 72 and the second mode adjustment valve 71 are both in mode 3; the a-b, d-e and g-h interfaces of the mode adjusting valve are communicated, so that intermediate media flow through the first cold air core 9, the first warm air core 11, the second cold air core 37 and the second warm air core 35.

Before the first and second mode adjusting valves 72 and 71, the flow of the high and low temperature intermediate medium in this mode is identical to that in the single-core normal cooling mode (i.e., mode one). After the first mode adjustment valve 72, the low temperature intermediate medium first flows into the first warm air core 11, cools the downstream intake air of the first air conditioning box module 13, then passes through the first mode adjustment valve 72, flows into the first cool air core 9 again, cools the upstream intake air of the first air conditioning box module 13, and finally returns to the first mode adjustment valve 72 and flows out. After the second mode adjusting valve 71, the low-temperature intermediate medium firstly flows into the second warm air core 35, cools the downstream intake air of the second air conditioning box module 39, then passes through the second mode adjusting valve 71, then flows into the second cool air core 37, cools the upstream intake air of the second air conditioning box module 39, and finally returns to the second mode adjusting valve 71 and flows out.

The first temperature damper 10 in the first air conditioning box module 13 and the second temperature damper 36 in the second air conditioning box module 39 are both in the fully open position. The inlet air of the first air conditioning box module 13 is sequentially cooled by the first cold air core 9 and the first warm air core 11, and the inlet air of the second air conditioning box module 39 is sequentially cooled by the second cold air core 37 and the second warm air core 35. Because the air inlet of the air conditioning box is cooled twice, the refrigeration power and efficiency of the system are improved compared with the conventional refrigeration of a single core body.

Fig. 15 shows the system operating mode three: conventional heating (single core) mode. The liquid inlet three-way valve 62 and the liquid return three-way valve 67 are both in the mode 1, and the a-c interfaces of the three-way valves are communicated. The first mode adjustment valve 72 and the second mode adjustment valve 71 are both in mode 2; the b-c and f-g interfaces of the mode regulating valve are communicated, so that intermediate media flow through the first warm air core body 11 and the second warm air core body 35; the a-h and d-e interfaces of the mode regulating valve are disconnected, so that no intermediate medium flows through the first cold air core 9 and the second cold air core 37.

The low-temperature intermediate medium in the intermediate medium cooler 58 passes through the cold-side medium pump 79 and the cold-side liquid inlet three-way valve 78, and then flows to the liquid inlet three-way valve 62. The low-temperature intermediate medium passes through the flow regulating valve 77 at the fully open position, absorbs heat from ambient air in the radiator 55, and then passes through the expansion tank 76, the liquid return three-way valve 67, the cold-side liquid return three-way valve 66 in order, and returns to the intermediate medium cooler 58. The fan assembly 56 may be turned on as needed to ensure ambient air flow through the radiator 55.

After passing through the hot-side medium pump 63, the electric heater 65 and the hot-side liquid inlet tee 64, the high-temperature intermediate medium in the intermediate medium heater 61 flows to the hot-side liquid inlet distribution manifold 69 and branches, and then flows into the first mode regulating valve 72 and the second mode regulating valve 71 respectively. In this mode, the electric heater 65 can be turned on to supplement heat to the high temperature intermediate medium according to the system requirements. The high-temperature intermediate medium of the first branch flows into the first warm air core 11, heats the inlet air of the first air conditioning box module 13, and then returns to the first mode adjusting valve 72 and enters the hot-side liquid return distribution multi-way 70; the high-temperature intermediate medium of the second branch flows into the second warm air core 35, heats the intake air of the second air conditioning box module 39, and then returns to the second mode adjusting valve 71 and enters the hot-side liquid return distribution multi-way 70. The multiple intermediate mediums are merged in the hot-side liquid return distribution manifold 70 and flow out, pass through the hot-side liquid return tee 68, and return to the intermediate medium cooler 61.

The first temperature damper 10 in the first air conditioning box module 13 and the second temperature damper 36 in the second air conditioning box module 39 are both in the fully open position; the intake air passes through the first warm air core 11 and the second warm air core 35 respectively and is heated, thereby realizing a conventional heating function.

Fig. 16 shows the system operating mode four: maximum heating/defrost (two cores in series) mode. The liquid inlet three-way valve 62 and the liquid return three-way valve 67 are both in the mode 1, and the a-c interfaces of the three-way valves are communicated. The first mode adjustment valve 72 and the second mode adjustment valve 71 are both in mode 5; the b-c, e-f and g-h interfaces of the mode regulating valve are communicated, so that the intermediate medium flows through the first cold air core 9, the first warm air core 11, the second cold air core 37 and the second warm air core 35.

Before the first and second mode adjusting valves 72 and 71, the flow of the high and low temperature intermediate medium in this mode is identical to that in the single-core normal heating mode (i.e., mode three). After the first mode adjustment valve 72, the high temperature intermediate medium first flows into the first warm air core 11, heats the downstream intake air of the first air conditioning box module 13, then passes through the first mode adjustment valve 72, flows into the first cool air core 9, heats the upstream intake air of the first air conditioning box module 13, and finally returns to the first mode adjustment valve 72 and flows out. After the second mode adjustment valve 71, the high temperature intermediate medium first flows into the second warm air core 35, heats the downstream intake air of the second air conditioning box module 39, then passes through the second mode adjustment valve 71, flows into the second cool air core 37, heats the upstream intake air of the second air conditioning box module 39, and finally returns to the second mode adjustment valve 71 and flows out.

The first temperature damper 10 in the first air conditioning box module 13 and the second temperature damper 36 in the second air conditioning box module 39 are both in the fully open position. The inlet air of the first air conditioning box module 13 is heated by the first cold air core 9 and the first warm air core 11 in sequence, and the inlet air of the second air conditioning box module 39 is heated by the second cold air core 37 and the second warm air core 35 in sequence. Because the air inlet of the air conditioning box is heated twice, the heating power and efficiency of the system are compared with the mode III: the conventional heating (single core) is improved.

Fig. 17 shows a fifth system operation mode: and a cooling and dehumidifying mode. The liquid inlet three-way valve 62 and the liquid return three-way valve 67 are both in the mode 2, and the b-c interfaces of the three-way valves are communicated. The first mode adjustment valve 72 and the second mode adjustment valve 71 are both in mode 1; the a-h, b-c, d-e and f-g ports of the mode adjusting valve are communicated, so that intermediate media flow through the first cold air core 9, the first warm air core 11, the second cold air core 37 and the second warm air core 35.

The flow of the low-temperature intermediate medium in the mode is completely the same as that in a single-core conventional refrigeration mode (namely, the mode one); the low-temperature intermediate medium flows into the first and second cold- air cores 9 and 37 through the first and second mode adjusting valves 72 and 71, respectively, and cools the upstream intake air of the first and second air- conditioning box modules 13 and 39.

The high temperature intermediate medium in the intermediate medium heater 61 passes through a hot side medium pump 63, an electric heater 65 and a hot side liquid inlet tee joint 64, and then is divided into two branches: the first branch flows to the hot-side inlet liquid distribution multi-way 69, and then flows into the first warm air core 11 and the second warm air core 35 through the first mode adjusting valve 72 and the second mode adjusting valve 71 respectively to heat the downstream inlet air of the first air conditioning box module 13 and the second air conditioning box module 39; then returns to the two mode adjusting valves, enters a hot side liquid return distribution multi-way 70 and flows into a hot side liquid return three-way 68. The second branch flows to the inlet three-way valve 62, passes through the flow control valve 77, radiates heat to the ambient air in the radiator 55, and then flows into the hot-side return three-way valve 68 through the expansion kettle 76 and the return three-way valve 67 in sequence. The two media are merged and flow out in the hot side liquid return tee 68 and return to the intermediate medium cooler 61. The fan assembly 56 may be turned on as needed to ensure ambient air flow through the radiator 55.

The electric heater 65 is not operated in this mode. The flow regulating valve 77 regulates the flow of the high-temperature intermediate medium flowing through the radiator 55 by changing the drift diameter thereof according to the system requirements, thereby regulating the heating power of the first warm air core 11 and the second warm air core 35.

The first temperature air door 10 in the first air conditioning box module 13 and the second temperature air door 36 in the second air conditioning box module 39 are both located at a certain middle position according to the outlet air temperature requirement of the system; the inlet air in the two air conditioning box modules respectively passes through the first cold air core body 9 and the second cold air core body 37 and is cooled, so that the humidity is reduced; then respectively pass through the first warm air core body 11 and the second warm air core body 35 and are heated, and the temperature rises back to the system requirement. In this mode, the refrigerating power of the cold air core is obviously higher than the heating power of the warm air core, and the air outlet temperature is lower than the air inlet temperature, so that the refrigerating and dehumidifying functions are realized.

Fig. 18 shows a sixth system operating mode: heating and dehumidifying mode. The liquid inlet three-way valve 62 and the liquid return three-way valve 67 are both in the mode 1, and the a-c interfaces of the three-way valves are communicated. The first mode adjustment valve 72 and the second mode adjustment valve 71 are both in mode 1; the a-h, b-c, d-e and f-g ports of the mode regulating valve are communicated, so that the intermediate medium flows through the first cold air core 9, the first warm air core 11, the second cold air core 37 and the second warm air core 35.

The flow of the high-temperature intermediate medium in the mode is completely the same as that in the conventional heating mode (namely, the mode III) of the single core body; the high-temperature intermediate medium flows into the first warm air core 11 and the second warm air core 35 through the first mode adjustment valve 72 and the second mode adjustment valve 71, respectively, and heats the downstream intake air of the first air conditioning box module 13 and the second air conditioning box module 39.

The low-temperature intermediate medium in the intermediate medium cooler 58 passes through a cold-side medium pump 79 and a cold-side liquid inlet tee 78, and then is divided into two branches: the first branch flows to the cold-side inlet liquid distribution multi-way 75, and then flows into the first cold air core 9 and the second cold air core 37 through the first mode adjusting valve 72 and the second mode adjusting valve 71 respectively to cool the upstream inlet air of the first air conditioning box module 13 and the second air conditioning box module 39; and then back to the two mode adjustment valves, into the cold side return distribution manifold 74, and into the cold side return tee 66. The second branch flows to the inlet three-way valve 62, passes through the flow control valve 77, absorbs the ambient air heat in the radiator 55, and then flows into the cold-side return three-way valve 66 through the expansion kettle 76 and the return three-way valve 67 in sequence. The two media combine in the cold side return tee 66 and exit back to the intercooler 58. The fan assembly 56 may be turned on as needed to ensure ambient air flow through the radiator 55.

In this mode, the electric heater 65 can be turned on to supplement heat to the high temperature intermediate medium according to the system requirements. The flow regulating valve 77 regulates the flow of the low-temperature intermediate medium flowing through the radiator 55 by changing the drift diameter thereof according to the system requirements, thereby regulating the refrigeration power of the first cold-air core 9 and the second cold-air core 37.

The first temperature damper 10 in the first air conditioning box module 13 and the second temperature damper 36 in the second air conditioning box module 39 are both in a fully open position; the air inlet in the two air conditioning box modules respectively passes through the first cold air core body 9 and the second cold air core body 37 and is cooled, so that the humidity is reduced; then respectively pass through the first warm air core body 11 and the second warm air core body 35 and are heated, and the temperature rises back to the system requirement. Because the refrigeration power of the cold air core is obviously lower than the heating power of the warm air core in the mode, the air outlet temperature is higher than the air inlet temperature, and the heating and dehumidifying functions are realized.

Fig. 19 shows a seventh system operating mode: and a demisting mode. The liquid inlet three-way valve 62 and the liquid return three-way valve 67 are both in the mode 3, and all the interfaces of the three-way valves are not communicated. The first mode adjustment valve 72 and the second mode adjustment valve 71 are both in mode 1; the a-h, b-c, d-e and f-g ports of the mode regulating valve are communicated, so that the intermediate medium flows through the first cold air core 9, the first warm air core 11, the second cold air core 37 and the second warm air core 35.

The flow of the low-temperature intermediate medium in the mode is completely the same as that in a single-core conventional refrigeration mode (namely a system working mode I); the low-temperature intermediate medium flows into the first and second cold air cores 9 and 37 through the first and second mode adjusting valves 72 and 71, respectively, and cools the upstream intake air of the first and second air conditioning box modules 13 and 39. The flow of the high-temperature intermediate medium is completely the same as that of a conventional heating mode (namely a system working mode III) of the single core body; the high-temperature intermediate medium flows into the first warm air core 11 and the second warm air core 35 through the first mode adjustment valve 72 and the second mode adjustment valve 71, respectively, and heats the downstream intake air of the first air conditioning case module 13 and the second air conditioning case module 39. No intermediate medium flows through front end cooling module 54 and fan assembly 56 is not operating.

The first temperature damper 10 in the first air conditioning box module 13 and the second temperature damper 36 in the second air conditioning box module 39 are both in a fully open position; the air inlet in the two air conditioning box modules respectively passes through the first cold air core 9 and the second cold air core 37 and is cooled, so that the humidity is reduced; then the air passes through the first warm air core body 11 and the second warm air core body 35 respectively and is heated, and the temperature rises. In this mode, the heating power of the warm air core is equal to the sum of the cooling power of the cold air core and the work of the compressor on the refrigerant, the air outlet temperature is slightly higher than the air inlet temperature, and the relative humidity is obviously lower than the air inlet temperature.

In the air distribution module 16 of the distributed air conditioning assembly, the first defrosting air door 22 and the second defrosting air door 30 of the first air distribution submodule 24 and the second air distribution submodule 32 are opened to guide the outlet air to the front window and the side window glass; thereby realizing the defogging function.

Fig. 20 shows the system operating mode eight: zone control (dual temperature zone). The modes of the liquid inlet three-way valve 62 and the liquid return three-way valve 67 are determined by the system working conditions and can be switched between the modes 1 to 3. The first mode adjustment valve 72 and the second mode adjustment valve 71 are both in mode 1; the a-h, b-c, d-e and f-g interfaces of the mode regulating valve are communicated.

The low-temperature intermediate medium flows into the first and second cold- air cores 9 and 37 through the first and second mode adjusting valves 72 and 71, respectively, and cools the upstream intake air of the first and second air- conditioning box modules 13 and 39. The high-temperature intermediate medium flows into the first warm air core 11 and the second warm air core 35 through the first mode adjustment valve 72 and the second mode adjustment valve 71, respectively, and heats the downstream intake air of the first air conditioning case module 13 and the second air conditioning case module 39. The first temperature air door 10 in the first air-conditioning box module 13 and the second temperature air door 36 in the second air-conditioning box module 39 are located at different intermediate positions according to the control signal, so that the air flows guided into the first warm air core 11 and the second warm air core 35 and heated by the air flows are different, different air outlet temperatures are generated after mixing, and the partitioned temperature control effect of the dual-temperature-zone air conditioner is achieved.

Based on the heat distribution condition of the whole system, the liquid inlet three-way valve 62 and the liquid return three-way valve 67 are in modes 1 to 3. Specifically, the method comprises the following steps: if the air conditioning assembly has an obvious heating function on the whole, the heat pump air conditioning system needs to absorb heat from the outside; at this time, the liquid inlet three-way valve 62 and the liquid return three-way valve 67 are in the mode 1, and the a-c interfaces of the three-way valves are communicated; the low temperature intermediate medium branches off a portion of the flow at the cold side inlet tee 78 to the radiator 55, absorbs ambient air heat and returns to the intermediate medium cooler 58. If the air conditioning assembly has a refrigeration function on the whole, the heat pump air conditioning system needs to release heat to the outside; at this time, the liquid inlet three-way valve 62 and the liquid return three-way valve 67 are in the mode 2, and the b-c interfaces of the three-way valves are communicated; the high temperature intermediate medium branches off a part of the flow at the hot side inlet tee 64 and enters the radiator 55, and returns to the intermediate medium heater 61 after releasing heat to the ambient air. If the air conditioning assembly has a heating function on the whole, but the heating power can be met by the compression work of the compressor without heat exchange between the system and the external environment; at this time, the liquid inlet three-way valve 62 and the liquid return three-way valve 67 are in the mode 3, and the high-temperature intermediate medium and the low-temperature intermediate medium do not enter the radiator 55. The flow regulating valve 77 controls the flow of the medium in the branch portion, and the fan assembly 56 can be opened as required.

Fig. 21 shows a ninth system operation mode: zone control (full cold full hot). This is the limit for zone control, with the first air conditioning box module 13 in a full cold state and the second air conditioning box module 39 in a full hot state.

The modes of the liquid inlet three-way valve 62 and the liquid return three-way valve 67 are determined by the system working conditions and can be switched between the modes 1 to 3. The first mode damper 72 is in mode 3 and the first temperature damper 10 is in the fully open position, such that the first air conditioning box module 13 is in the maximum cooling mode with the two cores in series; the second mode damper 71 is in mode 5 and the second temperature damper 36 is in the fully open position such that the second air conditioning box module 39 is in the maximum series two core heating mode.

Similar to the dual temperature zone partition control (i.e., the system operating mode eight), the liquid inlet three-way valve 62 and the liquid return three-way valve 67 are selected from modes 1 to 3 based on the heat distribution condition of the whole system.

Fig. 22 shows the system operating mode ten: and (5) melting ice. When the radiator is in a heating working condition for a long time and the environment humidity is high, icing may occur on the surface of the radiator to influence heat exchange. This mode is entered at this point. The liquid inlet three-way valve 62 and the liquid return three-way valve 67 are both in the mode 2, and the b-c interfaces of the three-way valves are communicated. The first mode adjustment valve 72 and the second mode adjustment valve 71 are both in mode 1; the a-h, b-c, d-e and f-g ports of the mode regulating valve are communicated, so that the intermediate medium flows through the first cold air core 9, the first warm air core 11, the second cold air core 37 and the second warm air core 35.

The flow mode of the intermediate medium is completely the same as that in the cooling and dehumidifying mode (i.e., the system operation mode five), and a part of the high-temperature intermediate medium flows into the radiator 55 through the liquid inlet three-way valve 62 and the flow rate adjusting valve 77. At this time, the fan assembly 56 is not turned on, and the amount of ambient air flowing through the heat sink is small, so that most of the heat emitted by the high-temperature medium is absorbed by the ice on the surface of the heat sink 55, thereby realizing the ice melting. In this mode the electric heater 65 can operate to increase the temperature of the medium and accelerate the speed of the ice melting.

The first temperature air door 10 and the second temperature air door 36 are both in full-open positions, and the first air blower 8 and the second air blower 38 are both operated at low speed, so that the temperature of the passenger compartment is not obviously influenced under the ice melting working condition.
