Description

Technical Field

[0001] This application relates to the field of automotive thermal management technology, specifically to an air conditioning unit, an air conditioning system, a control method for the air conditioning system, and a vehicle. Background Technology

[0002] Currently, the mainstream air handling methods are divided into three categories:

[0003] 1) Summer cooling: All air flows through the cold core (condenser), and the air is cooled and dehumidified by the refrigerant flowing through the cold core.

[0004] 2) Winter heating: Air flows through the cold core first and then through the warm core (evaporator). The cold core does not work, and the air is directly heated by the heat medium flowing through the warm core.

[0005] 3) Dehumidification in spring and autumn: Air flows through the cold core first and then through the warm core. The refrigerant flows through the cold core and the heat medium flows through the warm core, cooling and dehumidifying the air before heating it.

[0006] It is evident that during summer cooling and winter heating operations, one core element is always inactive, indicating a redundant design. Furthermore, the lack of valve control in the heating core element can cause a cooling-heating imbalance in the processed air during summer, reducing the system's COP (Coefficient of Performance).

[0007] In spring and autumn, the load inside the car is relatively low, but the dehumidification process requires a very low refrigerant temperature, which reduces the system's COP. Furthermore, to avoid thermal discomfort caused by excessively low supply air temperature, the cold air needs to be reheated, creating a heat-cold offsetting effect and further reducing the system's COP. Since the car's interior environment is primarily controlled by temperature, with humidity as a secondary factor, the heat-to-humidity ratio inside the car is not adjustable. This causes the temperature and humidity environment inside the car to deviate from the human comfort zone.

[0008] To address this issue, existing technologies disclose methods where cold water is first dehumidified in a low-temperature dehumidification section, and then the dehumidified and heated water flows into a dry coil to eliminate sensible heat load. However, this technology is primarily designed for residential use and has limitations in automotive applications. Existing technologies also disclose methods that utilize engine waste heat to regenerate a dilute solution, use the solution for dehumidification to treat the latent heat load of the air, and use the cooling energy released from LNG (Liquefied Natural Gas) vaporization to treat the sensible heat load of the air. However, these solutions can only be used when LNG is available, limiting their application scenarios. Summary of the Invention

Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features.

If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0043] First, this application provides an air conditioning unit 100, which can be used in vehicles. For example... Figure 1 As shown in the structural diagram, the air conditioning unit 100 may include a housing 110, a first heat exchange core 120, and a second heat exchange core 130.

[0044] like Figure 4a As shown, the housing 110 can be divided into a first space A and a second space B. The air outlet of one space A and the air inlet of the other are independent of each other; that is, there is no gas interaction between them, indicating that the first space A and the second space B are relatively independent. The air conditioning unit 100 may further include a first damper 111, disposed within the housing 110 and located between the first space A and the second space B. The first space A can be connected to or separated from the second space B through the first damper 111. Preferably, the first space A and the second space B are connected only when the first damper 111 is open, and are completely independent when the first damper 111 is closed.

[0045] The first heat exchange core 120 can be located at the air inlet of the first space A and can be used to heat-treat the first intake air. The heat treatment can include heating or cooling, specifically by introducing a high-temperature coolant (i.e., a heat transfer medium, indicated in red) or a low-temperature coolant (i.e., a refrigerant, indicated in blue) into the core to exchange heat with the first intake air, thereby achieving heating or cooling of the first intake air. Alternatively, room-temperature coolant can be introduced into the core, or no coolant can be introduced at all, so that there is no liquid flow inside, i.e., no heat exchange occurs between the core and the first intake air, thus not changing the intake air temperature. This approach is suitable for certain operating conditions where heat exchange requirements are not high, and can effectively save energy.

[0046] The second heat exchange core 130 can be located at the air inlet of the second space B and can be used to heat treat the second intake air. The heat treatment of the second intake air can be referred to the above description of the heat treatment of the first intake air. Preferably, the first and second intake air are independent of each other; that is, the discharged first intake air does not pass through the second heat exchange core 130, and the discharged second intake air does not pass through the first heat exchange core 120.

[0047] In this embodiment, the first heat exchange core 120 and the second heat exchange core 130 can be arranged side by side, that is, the first heat exchange core 120 and the second heat exchange core 130 can be arranged left and right. For example, Figure 2 As shown in a-2f, this is a top view of the arrangement of the first heat exchange core 120 and the second heat exchange core 130. Specifically, as... Figure 2 As shown in Figure a, the first air inlet plane (blue dashed line) of the first heat exchange core 120 and the second air inlet plane (blue dashed line) of the second heat exchange core 130 are parallel. Preferably, as shown in Figure a... Figure 2 As shown in b-2c, the first air inlet plane of the first heat exchange core 120 and the second air inlet plane of the second heat exchange core 130 are coplanar. Furthermore, a separating surface (red dashed line) can be formed between the first heat exchange core 120 and the second heat exchange core 130. For easier understanding, when there is partial overlap between the first heat exchange core 120 and the second heat exchange core 130, the gap between the first heat exchange core 120 and the second heat exchange core 130 can be ignored, and the plane containing the overlapping area between the first heat exchange core 120 and the second heat exchange core 130 can be called the separating surface. That is, the plane containing the area of ​​the first heat exchange core 120 close to the second heat exchange core 130 can be considered the separating surface, or the plane containing the area of ​​the second heat exchange core 130 close to the first heat exchange core 120 can be considered the separating surface. Wherein, as... Figure 2 As shown in d-2e, the projections of the first heat exchange core 120 and the second heat exchange core 130 on the separating surface can at least partially overlap. Preferably, as Figure 2As shown in Figure c, the projections of the first heat exchange core 120 on the partition surface completely overlap. In this case, the height and thickness of the first heat exchange core 120 and the second heat exchange core 130 can be equal, and the width of the first heat exchange core 120 can be less than or equal to the width of the second heat exchange core 130. Additionally, in some vehicle models, such as... Figure 2 As shown in Figure e, the first heat exchange core 120 and the second heat exchange core 130 can also be arranged front and back according to the installation space. Finally, as... Figure 2 As shown in f, the projections of the first heat exchange core 120 and the second heat exchange core 130 on the separating surface can also be independent of each other.

[0048] In another embodiment of this application, the first heat exchange core 120 and the second heat exchange core 130 can be stacked in the air intake direction, that is, the first heat exchange core 120 and the second heat exchange core 130 can be arranged vertically. Wherein, as Figure 3 As shown in a-3f, this is a side view of the arrangement of the first heat exchange core 120 and the second heat exchange core 130. Specifically, as... Figure 3 As shown in Figure a, the first air inlet plane of the first heat exchange core 120 and the second air inlet plane of the second heat exchange core 130 are parallel. Preferably, as shown in Figure a... Figure 3 As shown in b-3c, the first air inlet plane of the first heat exchange core 120 and the second air inlet plane of the second heat exchange core 130 are coplanar. Furthermore, a partition surface can be formed between the first heat exchange core 120 and the second heat exchange core 130. For example... Figure 3 As shown in d-3e, the projections of the first heat exchange core 120 and the second heat exchange core 130 on the separating surface can at least partially overlap. Preferably, as Figure 3 As shown in Figure c, the projections of the first heat exchange core 120 on the dividing surface completely overlap. In this case, the length and thickness of the first heat exchange core 120 and the second heat exchange core 130 can be equal, and the height of the first heat exchange core 120 can be less than or equal to the height of the second heat exchange core 130. Additionally, in some vehicle models, such as... Figure 3 As shown in Figure e, the first heat exchange core 120 and the second heat exchange core 130 can also be arranged front and back according to the installation space. Finally, as... Figure 3 As shown in f, the projections of the first heat exchange core 120 and the second heat exchange core 130 on the partition surface can also be independent of each other. However, it is worth noting that regardless of the positional relationship between the first heat exchange core 120 and the second heat exchange core 130, the two heat exchange cores are arranged independently and have their own heat exchange space and air outlet.

[0049] In the embodiments of this application, such as Figures 4a-4bAs shown, the housing 110 may further include: a second damper 112, located at the air outlet of the first space A, for discharging the first intake air when the first damper 111 is closed; and a third damper 113, located at the air outlet of the second space B, for discharging the second intake air when the first damper 111 is closed.

[0050] In another embodiment of this application, when the first damper 111 is open, the first intake air and the second intake air can be directly discharged from the second damper 112 and / or the third damper 113 according to the opening and closing status of the second damper 112 and the third damper 113. Preferably, the first intake air and the second intake air are independent of each other. That is, in one embodiment, the first intake air undergoes heat treatment only once in the first heat exchange core 120, and the first intake air discharged through the second damper 112 and / or the third damper 113 does not pass through the second heat exchange core 130; the second intake air undergoes heat treatment only once in the second heat exchange core 130, and the second intake air discharged through the second damper 112 and / or the third damper 113 does not pass through the first heat exchange core 120.

[0051] It is worth noting that the present invention only limits the first intake air from being discharged to not passing through the second heat exchange core 130, but does not limit the subsequent processing steps after the first intake air is discharged. That is, in another embodiment, the discharged first intake air can continue to undergo secondary heat treatment on other heat exchange cores (other than the second heat exchange core 130), and the discharged second intake air can also continue to undergo secondary heat treatment on other heat exchange cores (other than the first heat exchange core 120).

[0052] In the embodiments of this application, such as Figure 4a As shown, the housing 110 can be a two-zone air conditioning unit. In this case, the first space A can have a first air outlet, a defrost damper disposed at the first air outlet, a second air outlet, and a front airflow damper disposed at the second air outlet. The second space B can have a third air outlet, a front airflow damper disposed at the third air outlet, a fourth air outlet, and a rear airflow damper disposed at the fourth air outlet. That is, the second damper 112 can include a defrost damper and a front airflow damper, and the third damper 113 can include a front airflow damper and a rear airflow damper.

[0053] In addition, such as Figure 4b As shown, the enclosure 110 can be a three-zone air conditioning unit. In this case, the second space B may also include a fifth air outlet and a rear air outlet damper located at the fifth air outlet. That is, in addition to the front foot air outlet and the rear foot air outlet, the third air outlet 113 may also include a rear air outlet damper.

[0054] Through the above technical solution, the present invention aims to propose a new type of air conditioning unit that can solve the problem of the unadjustable heat-humidity ratio inside the vehicle without increasing the layout space, weight and cost of the air conditioning unit.

[0055] Furthermore, by employing two independently arranged cores, such as an upper and lower core arrangement, the NVH (Noise, Vibration, and Harshness) performance can be significantly reduced, both wind resistance and noise. Simultaneously, since this invention can alleviate or avoid the problem of heat and cold cancellation in existing solutions, it can enhance the system's COP (Coefficient of Performance), thus achieving energy-saving effects.

[0056] On the other hand, this application also provides an air conditioning system 200, such as Figure 5 As shown, the air conditioning system 200 may include the air conditioning unit 100 mentioned above and the controller 210. The controller 210 can be used to control the opening and closing of the first damper 111 and to control at least one of the first heat exchange core 120 and the second heat exchange core 130 to perform heating or cooling operations.

[0057] Specifically, controlling at least one of the first heat exchange core 120 and the second heat exchange core 130 to perform heating or cooling operations may include:

[0058] 1) Control one of the first heat exchange core 120 and the second heat exchange core 130 to perform heating or cooling operations, while the other does not operate.

[0059] 2) Control one of the first heat exchange core 120 and the second heat exchange core 130 to perform heating operation, and the other to perform cooling operation.

[0060] 3) Control both the first heat exchange core 120 and the second heat exchange core 130 to perform heating or cooling operations simultaneously.

[0061] In this embodiment of the application, the controller 210 can also be used to perform the following functions:

[0062] 1) In cooling mode, at least one of the first heat exchange core 120 and the second heat exchange core 130 is controlled to perform cooling operation. This cooling mode is applicable to summer cooling and specifically includes: controlling the first damper 111 to close, controlling one of the first heat exchange core 120 and the second heat exchange core 130 to perform cooling operation, while the other does not operate; or, controlling the first damper 111 to open or close, controlling both the first heat exchange core 120 and the second heat exchange core 130 to perform cooling operation. In one embodiment, refer to... Figure 4a In the refrigeration mode, a low-temperature refrigerant (marked in blue) is passed through the upper core and / or lower core to cool the air passing through the upper core and / or lower core before it is sent to the subsequent distribution section.

[0063] 2) In heating mode, at least one of the first heat exchange core 120 and the second heat exchange core 130 is controlled to perform heating operations. This heating mode is applicable to winter heating and specifically includes: controlling the first damper 111 to open or close, controlling one of the first heat exchange core 120 and the second heat exchange core 130 to perform heating operations while the other does not operate; controlling the first damper 111 to open or close, controlling both the first heat exchange core 120 and the second heat exchange core 130 to perform heating operations. In one embodiment, refer to... Figure 4a In the heating mode, a high-temperature heat medium (marked in red) is passed through the upper core and / or lower core to directly heat the air passing through the upper core and / or lower core, and then it is sent to the subsequent distribution section.

[0064] 3) In dehumidification mode, the first damper 111 is opened, and one of the first heat exchange core 120 and the second heat exchange core 130 is controlled to perform cooling operation. This dehumidification mode is applicable to dehumidification in spring and autumn, specifically including: opening the first damper 111, controlling one of the first heat exchange core 120 and the second heat exchange core 130 to perform cooling operation, while the other performs heating operation or does not operate. In one embodiment, refer to... Figure 4a In the dehumidification mode, a low-temperature refrigerant is passed through the upper core to cool and dehumidify the air passing through it; a high-temperature heat transfer medium is passed through the lower core to heat the air passing through it, and then the two air streams are mixed before being sent to the subsequent distribution section. Alternatively, a low-temperature refrigerant can be passed through the lower core and a high-temperature heat transfer medium can be passed through the upper core, and then the two air streams are mixed before being sent to the subsequent distribution section.

[0065] In this embodiment, under dehumidification conditions, the controller 210 can also perform the following functions: controlling and adjusting the intake ratio of the first air intake and the second air intake, thereby achieving further regulation of air temperature and humidity. Additionally, the controller 210 can also control and adjust the heat exchange power (including heating power or cooling power, manifested as increasing or decreasing the temperature of the coolant flowing into the core) of the first heat exchange core 120 and / or the second heat exchange core 130, thereby combining the intake ratio of the first air intake and the second air intake to better achieve further regulation of air temperature and humidity. Specifically, in one embodiment, when the first heat exchange core 120 is performing cooling operations, the air humidity can be reduced by controlling and adjusting one or more of the following: increasing the intake of the first heat exchange core 120, decreasing the cooling power of the first heat exchange core 120, and reducing the intake of the first heat exchange core 120. Correspondingly, in another embodiment, the humidity of the air can be increased by controlling one or more of the following: reducing the air intake of the first heat exchange core 120, increasing the cooling power of the first heat exchange core 120, and increasing the air intake of the first heat exchange core 120.

[0066] Therefore, by controlling the first heat exchange core 120 and the second heat exchange core 130 separately through the controller 210, independent temperature and humidity control functions can be achieved inside the vehicle, and the heat-to-humidity ratio of the air inside the vehicle can be adjusted, resulting in better thermal comfort of the overall vehicle environment. Furthermore, the solution of this invention achieves heating, cooling, and dehumidification functions with only one heat exchange, eliminating the need for the secondary heat exchange mode in existing technologies. Therefore, it can be arranged within the space of a single core, saving the cost of at least one core and gaining additional space for its arrangement. This saves space in the X-direction of the vehicle and reduces the weight and cost of the air conditioning unit.

[0067] On the other hand, embodiments of this application also provide a control method for an air conditioning system, which may include the aforementioned air conditioning unit 100. For example... Figure 6 As shown in the flowchart, the control method may include step S110.

[0068] In step S110, under dehumidification conditions, the first damper of the air conditioning system is opened, and one of the first heat exchange core 120 and the second heat exchange core 130 is controlled to perform cooling operations.

[0069] In this embodiment of the application, under dehumidification conditions, step S110 further includes step S111 or step S112.

[0070] In step S111, when the first heat exchange core 120 is performing cooling operation, the humidity of the air is reduced by controlling and adjusting one or more of the following: increasing the air intake of the first heat exchange core 120, reducing the cooling power of the first heat exchange core 120, and reducing the air intake of the first heat exchange core 120.

[0071] Step S112, increase the humidity of the air by controlling and adjusting one or more of the following: reduce the air intake of the first heat exchange core 120, increase the cooling power of the first heat exchange core 120, and increase the air intake of the first heat exchange core 120.

[0072] In the embodiments of this application, the control method may further include steps S120 or S130.

[0073] Step S120: In cooling mode, at least one of the first heat exchange core 120 and the second heat exchange core 130 is controlled to perform cooling operation. This cooling mode is applicable to summer cooling and specifically includes: controlling the first damper 111 to close, controlling one of the first heat exchange core 120 and the second heat exchange core 130 to perform cooling operation, while the other does not operate; or, controlling the first damper 111 to open or close, controlling both the first heat exchange core 120 and the second heat exchange core 130 to perform cooling operation. In one embodiment, refer to... Figure 4aIn the refrigeration mode, a low-temperature refrigerant (marked in blue) is passed through the upper core and / or lower core to cool the air passing through the upper core and / or lower core before it is sent to the subsequent distribution section.

[0074] Step S130: In heating mode, at least one of the first heat exchange core 120 and the second heat exchange core 130 is controlled to perform heating operations. This heating mode is applicable to winter heating and specifically includes: controlling the first damper 111 to open or close, controlling one of the first heat exchange core 120 and the second heat exchange core 130 to perform heating operations while the other does not operate; or controlling the first damper 111 to open or close, controlling both the first heat exchange core 120 and the second heat exchange core 130 to perform heating operations. In one embodiment, refer to... Figure 4a In the heating mode, a high-temperature heat medium (marked in red) is passed through the upper core and / or lower core to directly heat the air passing through the upper core and / or lower core, and then it is sent to the subsequent distribution section.

[0075] In this embodiment, the housing 110 may further include: a second damper 112 for discharging the first intake air when the first damper 111 is closed; and a third damper 113 for discharging the second intake air when the first damper 111 is closed. In this embodiment, the control method of the present invention may further include: controlling the opening and closing of the second damper 112 and the third damper 113.

[0076] In another embodiment of this application, when the first damper 111 is open, the first intake air and the second intake air can be directly discharged from the second damper 112 and / or the third damper 113 according to the opening and closing status of the second damper 112 and the third damper 113. Preferably, the first intake air and the second intake air are independent of each other. That is, in one embodiment, the first intake air undergoes heat treatment only once in the first heat exchange core 120, and the first intake air discharged through the second damper 112 and / or the third damper 113 does not pass through the second heat exchange core 130; the second intake air undergoes heat treatment only once in the second heat exchange core 130, and the second intake air discharged through the second damper 112 and / or the third damper 113 does not pass through the first heat exchange core 120.

[0077] It is worth noting that the present invention only limits the first intake air from being discharged to not passing through the second heat exchange core 130, but does not limit the subsequent processing steps after the first intake air is discharged. That is, in another embodiment, the discharged first intake air can continue to undergo secondary heat treatment on other heat exchange cores (other than the second heat exchange core 130), and the discharged second intake air can also continue to undergo secondary heat treatment on other heat exchange cores (other than the first heat exchange core 120).
