Description

An integrated system and control method for vehicle air conditioning and cooling or heating devices. Technical Field

[0001] This invention relates to an integrated system and control method for vehicle air conditioning and cooling or heating devices. Background Technology

[0002] A traditional automotive air conditioning centralized air supply system includes an air intake duct, a cooling / heating system, and an air supply duct, as shown in Figures 1 and 2. The air intake duct has two air inlets: one air inlet 1a supplies fresh air, and the other air inlet 2a supplies internal recirculated air. The outlet of the air intake duct is connected to the cooling / heating system, and the outlet of the cooling / heating system is connected to the air supply duct. The cooling / heating system includes a high-power air supply fan 3a, an evaporator 4a, a compressor, a throttle valve, a condenser, and a radiator fan. The cooling / heating system cools the air in the air intake duct and then delivers it to the air supply duct. At the end of the air supply duct are multiple air outlets 5a, with the outlets of each air outlet 5a located in different areas of the passenger compartment. At the end of each air outlet duct is a valve switch that controls the airflow. Traditional automotive air conditioning systems have the following drawbacks: 1. High-powered air supply fans are too large and are placed in the engine compartment, severely restricting the space layout of the engine compartment; 2. After the high-powered air supply fans deliver cold / hot air, it is transmitted through the air ducts, especially the long duct transmission in the rear area, resulting in significant air volume loss and reducing the energy efficiency of the air supply system; 3. The air supply fans in centralized air supply systems directly deliver cold / hot air to the end of the air outlet and blow it onto the passengers, causing the passengers' body temperature to change too quickly and reducing comfort; 4. Centralized air supply systems cannot provide differentiated air supply management for each air outlet. Passengers in different positions cannot set different fan speeds according to their individual needs. They can only use valves at each air outlet to intercept airflow by opening and closing the valves, resulting in wasted airflow; 5. The air supply fans in centralized air supply systems directly deliver cold air to the end of the air outlet and blow it onto the passengers, causing the passengers' body temperature to change too quickly and reducing comfort. 6. Traditional car ventilation works by using the vehicle's inertia to push fresh air into the vehicle while it is in motion. However, unmanaged hot and cold air from outside can affect the air conditioning performance, increasing energy consumption and reducing passenger comfort.

[0003] Furthermore, with the development of new energy electric vehicles, the three core components of electric vehicles—drive motor, power battery, and drive control system—are the components that generate the most heat during operation, making their heat dissipation systems particularly important. The traditional manufacturing method uses liquid cooling, i.e., laying liquid cooling pipes to dissipate heat from the drive motor and drive control system. However, laying liquid cooling pipes also involves sealing issues, leading to complex product structures, high manufacturing costs, and low integration. Research and experiments have found that the drive motor generates the most heat and must use liquid cooling to effectively remove it. However, the power battery and drive control system generate relatively little heat during operation and can be cooled using air cooling, which can reduce the various problems associated with laying liquid cooling pipes, simplify the structure, and lower manufacturing costs.

[0004] Third, for electric vehicles operating in frigid environments, the drive motor, power battery, and drive control system must not only consider heat dissipation, but also ensure that the power battery and drive control system can start and work normally at a reasonable operating temperature.

[0005] Therefore, it is necessary to redesign a new system to effectively control the operating temperature of the power battery and drive control system.

[0006] Summary of the Invention

[0007] This invention provides an integrated system and control method for vehicle air conditioning and cooling or heating devices, which solves the technical problems of existing electric vehicle operating temperature control systems for power batteries and drive control systems, which are complex in structure, poor in integration, and high in cost.

[0008] The technical solution of this invention is implemented as follows:

[0009] An integrated system for vehicle air conditioning and cooling or heating devices includes a power air vent system, wherein: the power air vent system includes an air inlet duct, a cooling / heating system, and an air supply duct. The air inlet duct is provided with a fresh air inlet and an internal circulation air inlet. The outlet of the air inlet duct is connected to the cooling / heating system. The cooling / heating system includes a high-power air supply fan and a heat exchanger. The outlet of the cooling / heating system is connected to the air supply duct. Multiple air outlet ducts are provided at the end of the air supply duct. A terminal air supply system is provided at the outlet of the air outlet duct. The terminal air supply system includes a low-power air supply fan and a low-speed fan. The low-power air supply fan is located at the end of the air outlet duct, and the low-speed fan is located next to the outlet of the air outlet duct. The terminal air supply system mixes the low / high temperature airflow output by the cooling / heating system with the ambient temperature airflow inside the vehicle and blows it to the user's position inside the vehicle compartment.

[0010] The feature is that it also includes a cooling or heating device, which includes multiple third pipes installed from the end of the air supply pipe, and a cooling fan installed in each third pipe. The cooling fan uses the low / high temperature airflow output by the refrigeration / heating system to dissipate heat or heat the power battery and / or drive control system on the vehicle.

[0011] The aforementioned terminal air supply system is controlled by the central control system. The cooling fan of the cooling or heating device is also controlled by the central control system. The power battery and / or drive control system is equipped with a temperature sensor. The temperature sensor measures the operating temperature of the power battery and / or drive control system and sends it to the central control system. Based on the operating temperature of the power battery and / or drive control system, the central control system uses the cooling fan to dissipate heat or heat the power battery and / or drive control system on the vehicle by using the low / high temperature airflow output by the cooling / heating system.

[0012] The aforementioned vehicle air conditioning and cooling or heating device integrated system also includes a fresh air exchange device, which includes a first duct and a second duct. A suction fan is installed in the first duct, which actively draws fresh air into the vehicle compartment through the inlet of the first duct under the action of the suction fan. An exhaust fan is installed in the second duct, which is connected to the interior of the vehicle compartment. Under the action of the exhaust fan, the stale air inside the vehicle compartment is discharged outside the vehicle through the outlet of the second duct.

[0013] Two exhaust fans are installed inside the second pipe, and the two exhaust fans are respectively located at the two ends near the second pipe.

[0014] The aforementioned suction fans and exhaust fans are both high-speed small fans used in ducts.

[0015] The aforementioned terminal air supply system also includes an air supply control unit, which controls the operation of the low-power air supply fan and low-speed fan in the terminal air supply system to which it belongs, and the central control system controls the operation of each air supply control unit.

[0016] The aforementioned suction fan and exhaust fan are both controlled by the central control system. An air conditioning device is also installed in the first duct, which includes a filter, a surface cooler, and a humidifier. A fresh air temperature sensor and a fresh air valve are installed at the fresh air inlet of the first duct. The fresh air temperature sensor sends the detected temperature signal to the central control system, which then controls the fresh air valve and the air conditioning device to operate.

[0017] The aforementioned refrigeration / heating system also includes a compressor, a throttle valve, a cooling fan, and a radiator, and the heat exchanger is an evaporator.

[0018] The aforementioned power battery supplies power to the vehicle's drive motor, and the aforementioned drive control system controls the operation of the vehicle's drive motor.

[0019] A control method for a vehicle air conditioning and cooling or heating device integrated system, wherein the vehicle air conditioning and cooling or heating device integrated system adopts the aforementioned vehicle air conditioning and cooling or heating device integrated system, characterized in that: its control method is as follows:

[0020] Temperature sensors detect the temperature of the power battery or drive control system. When the temperature is higher or lower than the effective operating temperature range of the power battery or drive control system, the temperature sensor transmits a signal to the central control system. The central control system automatically controls the cooling fan to blow the cold or hot air output by the cooling / heating system onto the power battery or drive control system to dissipate heat or heat the power battery or drive control system until the temperature of the power battery or drive control system reaches the set operating temperature range. Then, the central control system automatically shuts down the cooling fan or reduces the speed of the cooling fan, and this cycle repeats continuously.

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] 1. This invention integrates the vehicle's air conditioning system with a cooling or heating device, employing an air-cooled design for the power battery and / or drive control system. The cooling or heating device is embedded within the vehicle's air conditioning system, comprising multiple third pipes extending from the end of the air supply duct. Each third pipe houses a cooling fan, which uses the low / high temperature airflow output from the cooling / heating system to dissipate heat or heat the vehicle's power battery and / or drive control system. This simplifies the structure, reduces manufacturing costs, and achieves a high degree of integration.

[0023] 2. This invention adds a power air outlet at the end of the power air outlet system at the power battery or drive control system. That is, multiple third pipes are provided from the end of the air supply pipe, and a cooling fan is installed in each third pipe. At the same time, the temperature of the battery or drive system is sensed, and the central control system is centrally and automatically controlled through the central control system to realize the comprehensive use and centralized management of the energy of the vehicle's air conditioning and cooling system, thereby achieving energy saving in the vehicle.

[0024] 3.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1:

[0035] As shown in Figures 3, 4, 5, 6, and 7, this embodiment provides an integrated system for vehicle air conditioning and cooling or heating devices, including a power air vent system 100, wherein:

[0036] The power air outlet system 100 includes an air inlet duct 1, a cooling / heating system 2, and an air supply duct 3. The air inlet duct 1 is provided with a fresh air inlet 11a and an internal circulation air inlet 11b. The outlet of the air inlet duct 1 is connected to the cooling / heating system 2. The cooling / heating system 2 includes a high-power air supply fan 21 and a heat exchanger 22. The outlet of the cooling / heating system 2 is connected to the air supply duct 3. The end of the air supply duct 3 is provided with multiple air outlet ducts 31. A terminal air supply system 4 is provided at the outlet of the air outlet duct 31. The terminal air supply system 4 includes a low-power air supply fan 41 and a low-speed fan 42. The low-power air supply fan 41 is provided with... A low-speed fan 42 is positioned next to the outlet of the air duct 31 at the end of the air duct 31. The terminal air supply system 4 mixes the low / high temperature airflow output by the cooling / heating system 2 with the ambient temperature airflow inside the vehicle and blows it to the user's position inside the vehicle compartment. The feature is that it also includes a cooling or heating device 7, which includes multiple third pipes 71 set from the end of the air duct 3. Each third pipe 71 is equipped with a cooling fan 72. The cooling fan 72 uses the low / high temperature airflow output by the cooling / heating system 2 to dissipate heat or heat the power battery and / or drive control system on the vehicle.

[0037] As shown in Figure 4, the refrigeration / heating system 2 also includes a compressor, a throttle valve, a condenser, and a cooling fan.

[0038] The aforementioned terminal air supply system 4 is controlled by the central control system 6. The cooling fan 72 of the cooling or heating device 7 is also controlled by the central control system 6. The power battery and / or drive control system is equipped with a temperature sensor 73. The temperature sensor 73 measures the operating temperature of the power battery and / or drive control system and sends it to the central control system 6. Based on the operating temperature of the power battery and / or drive control system, the central control system 6 uses the cooling fan 72 to dissipate heat or heat the power battery and / or drive control system on the vehicle by using the low / high temperature airflow output by the cooling / heating system 2.

[0039] Advantages of this invention: 1. It integrates the vehicle air conditioning system with a cooling or heating device, employing an air-cooled design for the power battery and / or drive control system. The cooling or heating device is embedded within the vehicle air conditioning system, comprising multiple third pipes extending from the end of the air supply duct. Each third pipe houses a cooling fan, which uses the low / high temperature airflow from the cooling / heating system to dissipate heat or heat the vehicle's power battery and / or drive control system. This simplifies the structure, reduces manufacturing costs, and achieves high integration. 2. This invention adds a power air vent system at the end of the power battery or drive control system, i.e., multiple third pipes extending from the end of the air supply duct, each housing a cooling fan. Simultaneously, it senses the temperature of the battery or drive system and centrally and automatically controls the central control system 6, achieving comprehensive utilization and centralized management of energy from the vehicle's air conditioning and cooling systems, thereby realizing vehicle energy conservation.

[0040] As shown in Figure 5, the power air vent system 100 includes a fresh air exchange device 5, which comprises a first duct 51 and a second duct 53. A suction fan 52 is installed in the first duct 51, actively drawing fresh air into the vehicle compartment through the inlet of the first duct 51 under the action of the suction fan 52. An exhaust fan 54 is installed in the second duct 53, whose inlet is connected to the interior of the vehicle compartment. The exhaust fan 54 expels stale air from the vehicle compartment through the outlet of the second duct 53. Fans are installed inside the first duct 51 and the second duct 53, respectively at the front and rear ends of the ducts. The two fans create a siphon effect within the ducts, generating negative pressure and improving the airflow efficiency of the fan system. The suction fan 52 and the exhaust fan 54 can be centrally controlled by the air conditioning central control system 6, effectively managing the energy consumption of the vehicle's air conditioning system and enhancing passenger comfort.

[0041] The aforementioned suction fan 52 and exhaust fan 54 are both high-speed small fans used in ducts.

[0042] The aforementioned terminal air supply system 4 is controlled by the central control system 6.

[0043] The aforementioned exhaust fan 54 is controlled by the central control system 6.

[0044] The aforementioned low-power air supply fan 41 is located diagonally behind the low-speed fan 42. The high-speed low-power air supply fan 41 blows the low / high-temperature airflow from the cooling / heating system 2 behind the low-speed fan 42. The low-speed fan 42 mixes the low / high-temperature airflow with the ambient airflow and then blows it to the user's location. The mixing of the low / high-temperature airflow with the ambient airflow by the low-speed fan 42 makes the air temperature and speed more comfortable.

[0045] The aforementioned terminal air supply system 4 also includes an air supply control unit 43. The air supply control unit 43 controls the operation of the high-speed, low-power air supply fan 41 and the low-speed fan 42 within its terminal air supply system 4. The central control system 6 controls the operation of each air supply control unit 43. Users in different locations can set the airflow speed of the terminal air supply system 4 according to their individual needs, better meeting diverse user requirements and enhancing the user experience. The air supply control unit 43 can actually be an integrated motor controller, capable of simultaneously controlling the low-power air supply fan 41 and the low-speed fan 42. The central control system 6 is the central control system of the air conditioner, and will not be described in detail here.

[0046] The aforementioned terminal air supply system 4 also includes an infrared / temperature sensing system 44. The infrared / temperature sensing system 44 senses the user's location and sends the sensing signal to the central control system 6. The central control system 6 controls the operation of each air supply control unit 43 based on the sensing signal. The central control system 6 can control the operation of each terminal air supply system 4 differently.

[0047] The air delivery angles of the aforementioned low-power blower 41 and low-speed fan 42 are adjustable; for example, the air delivery angle can be adjusted within the range of 10 degrees to 90 degrees.

[0048] The aforementioned user location status includes whether or not user awareness is present, temperature awareness, and sleep awareness.

[0049] The infrared / temperature sensing system 44 identifies whether there is a user in the seat, whether the user is asleep, and whether the user's body temperature is too high or too low. The system then automatically adjusts the temperature and airflow to the optimal level for each user's location through a centralized control system, improving user comfort and saving energy.

[0050] Both the intake fan 52 and the exhaust fan 54 are controlled by the central control system 6. An air conditioning device 55, including a filter, a surface cooler, and a humidifier, is installed inside the first duct 51. A fresh air temperature sensor 57 and a fresh air valve 56 are installed at the fresh air inlet of the first duct 51. The fresh air temperature sensor 57 sends the detected temperature signal to the central control system 6, which then controls the operation of the fresh air valve 56 and the air conditioning device 55. The central control system 6 controls the opening and closing of the fresh air valve 56, thereby controlling the intake of fresh air.

[0051] By improving the power vent system, the car becomes more energy-efficient and the passenger (i.e., user) experience is more comfortable. Its advantages include:

[0052] 1. In automotive applications, the high-power centralized air supply fan inside the engine compartment has been eliminated. Instead, a high-power air supply fan 21 has been added to the centralized air supply duct. This allows for better spatial layout of the engine compartment and improves the rationality of the engine compartment space design.

[0053] 2. In automotive applications, the air blown by the high-power blower 21 is compensated by adding a high-speed low-power blower in the duct at the end of the air outlet, which creates a siphon effect in the duct to generate negative pressure, reducing the air volume attenuation of cold (or hot) air in the duct and improving the air delivery efficiency of the blower system.

[0054] 3. In automotive applications, each air duct 31 has an independent air supply control unit 43, which controls the low-power air supply fan 41 of each air duct 31 respectively; at the same time, there is also a central control system 6 in the center console for centralized control, which can control the speed of the low-power air supply fan 41 of each air duct 31 differently.

[0055] 4. A low-power air supply fan 41 is installed in each air outlet duct 31. People in different positions can set different speeds of the low-power air supply fan 41 according to their individual needs, which better meets the differentiated needs of the personnel and improves their experience.

[0056] 5. An infrared / temperature sensing system 44 is added to each air outlet duct 31. It can identify whether there is a person in the seat, whether the person is sleeping, and whether the person's body temperature is too high or too low. The system can also automatically adjust the temperature and airflow to the optimal state for different people's positions through the central control system 6 to improve the comfort of people.

[0057] 6. Add a low-speed fan 42 to each air outlet duct 31 to mix the ambient air with the cold (hot) air blown out by the low-power blower 41 and blow it onto the personnel to form a natural breeze and improve the comfort of the personnel.

[0058] 7. The new air conditioning system can achieve constant air volume control, reducing the risk of reduced air volume caused by increased static pressure in the duct due to factors such as filter blockage, and improving the user experience of air conditioning cooling effect.

[0059] Example 2

[0060] As shown in Figures 6 and 7, a control method for a vehicle air conditioning and cooling or heating device integrated system is provided. The vehicle air conditioning and cooling or heating device integrated system adopts the vehicle air conditioning and cooling or heating device integrated system described in Embodiment 1. The control method is as follows: The temperature of the power battery or drive control system is sensed by the temperature sensor 73. When the temperature is higher or lower than the effective operating temperature range of the power battery or drive control system, the temperature sensor transmits a signal to the central control system 6. The central control system 6 automatically controls the cooling fan 72 to blow the cold or hot air output by the cooling / heating system 2 onto the power battery or drive control system to dissipate heat or heat the power battery or drive control system until the temperature of the power battery or drive control system reaches the set safe operating temperature. Then, the central control system 6 automatically shuts down the cooling fan 72 or reduces the speed of the cooling fan 72. This cycle repeats continuously.

[0061] A specific example is as follows: Assume the appropriate operating temperature for the power battery is set within the range of T1-T2, where T1 equals 25 degrees Celsius and T2 equals 40 degrees Celsius. The temperature sensor 73 installed on the power battery senses the current temperature T0. When T0 is less than T1, the central control system 6 automatically controls the cooling fan 72 to blow hot air from the cooling / heating system 2 onto the power battery, raising its temperature. When the power battery's operating temperature is within the T1-T2 range, the central control system 6 automatically shuts off the cooling fan 72 or reduces its speed. When T0 is greater than T2, the central control system 6 automatically controls the cooling fan 72 to blow cold air from the cooling / heating system 2 onto the power battery, cooling it. When the power battery's operating temperature is within the T1-T2 range, the central control system 6 automatically shuts off the cooling fan 72 or reduces its speed, and this cycle repeats continuously. Of course, the cooling / heating system 2 is controlled by the central control system 6. The specific temperature control of the drive control system follows the same principle as the power battery's temperature control. However, the suitable operating temperature range may vary slightly. For example, the suitable operating range for drive control systems is between 20 degrees Celsius and 45 degrees Celsius.

[0062] The control method of the present invention can effectively control the operating temperature of the power battery or drive control system, and is suitable for different working environments such as extreme cold or high temperature, thereby extending its service life, reducing the occurrence of failures, and the control is simple and reliable.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
