Description

Technical Field

[0001] This invention relates to the field of vehicle heating technology, and in particular to a linkage control system and method for air conditioning and vehicle heating. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] The existing method for heating buses is to install air conditioners on the roof of the bus and use these air conditioners to heat the vehicle. Figure 1 As shown, or a PTC radiator can be installed at the bottom of the vehicle to heat the vehicle, such as... Figure 2 As shown.

[0004] However, the inventor believes that when a vehicle is heated individually by an air conditioner or radiator, problems such as "hot head and cold feet" or "cold head and relatively hot feet" can easily occur. This cannot evenly regulate the temperature inside the vehicle, which seriously affects the driver's operating experience and the passenger's riding experience. Summary of the Invention

[0005] To address the aforementioned problems, this invention proposes a linkage control system and method for air conditioning and vehicle heating. By linking the air conditioner installed on the roof of the vehicle and the radiator installed at the bottom, the interior temperature reaches the set value, and the temperature of the three-dimensional space inside the vehicle is balanced, ensuring that the driver and passengers are kept warm from head to toe, ultimately achieving a comfortable riding experience.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Firstly, a linkage control system for air conditioning and vehicle heating is proposed, including air conditioning, driver's area radiator and passenger area radiator; the refrigerant circuit of the air conditioning is connected to the water circuit through a heat exchanger, and the water in the water circuit and the refrigerant in the refrigerant circuit exchange heat through the heat exchanger, and driver's area radiator and passenger area radiator are installed on the water circuit.

[0008] The temperature acquisition module is used to acquire the temperature of the driver's area, the temperature of the passenger area, and the water temperature in the water circuit after heat exchange.

[0009] The controller is used to control the radiator fan in a certain area to operate at low speed when the air conditioning is in heating mode, the driver's area radiator fan, and the passenger area radiator fan are turned on, and the temperature in a certain area is less than or equal to a first set value for that area, while the water temperature in the water circuit is greater than a first temperature value; when the temperature in a certain area is less than or equal to the first set value for that area, while the water temperature in the water circuit is greater than a second temperature value, the controller controls the radiator fan in that area to operate at high speed; when the temperature in a certain area is greater than the first set value but less than or equal to the second set value for that area, the controller keeps the radiator fan in that area operating at a constant speed; and when the temperature in a certain area is greater than the second set value for that area, the controller turns off the radiator fan in that area.

[0010] Secondly, a control method for a linkage control system of air conditioning and vehicle heating is proposed, including:

[0011] When the air conditioning is in heating mode, the radiator fan in the driver's area and the radiator fan in the passenger area are turned on, the driver's area temperature, the passenger area temperature and the water temperature in the water circuit after heat exchange by the heat exchanger are obtained.

[0012] When the temperature of a certain zone is less than or equal to the first set value of that zone, and the water temperature in the water circuit is greater than the first temperature value, the radiator fan in that zone is controlled to operate at low speed; when the temperature of a certain zone is less than or equal to the first set value of that zone, and the water temperature in the water circuit is greater than the second temperature value, the radiator fan in that zone is controlled to operate at high speed; when the temperature of a certain zone is greater than the first set value of that zone but less than or equal to the second set value of that zone, the radiator fan in that zone remains unchanged; when the temperature of a certain zone is greater than the second set value of that zone, the radiator fan in that zone is controlled to shut down.

[0013] Thirdly, an electronic device is proposed, including a memory and a processor, as well as computer instructions stored in the memory and running on the processor. When the computer instructions are executed by the processor, they complete the steps described in the control method for a linkage control system of air conditioning and vehicle heating.

[0014] Fourthly, a computer-readable storage medium is proposed for storing computer instructions, which, when executed by a processor, complete the steps described in the control method for a linkage control system of air conditioning and vehicle heating.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. This invention enables the coordinated control of the air conditioner installed on the roof of the vehicle and the radiator installed at the bottom, so that the interior temperature reaches the set value and achieves temperature balance in the three-dimensional space of the vehicle, reducing temperature stratification inside the vehicle and ensuring that the driver and passengers are kept warm from head to toe, ultimately achieving a comfortable riding experience.

[0017] 2. This invention connects the radiator to the refrigerant circuit of the air conditioner through a heat exchanger, and controls the working state of the radiator fan based on the temperature of the driver's area, the temperature of the passenger area, and the water temperature in the water circuit after heat exchange through the heat exchanger. Based on the linkage control of the air conditioner and the radiator, it effectively ensures the temperature balance of the three-dimensional space inside the vehicle and reduces energy consumption.

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0030] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0031] Example 1

[0032] In this embodiment, a linkage control system for air conditioning and vehicle heating is disclosed, including an air conditioner, a driver's area radiator, a passenger area radiator, a temperature acquisition module, and a controller, wherein the driver's area radiator and the passenger area radiator generate vehicle heating.

[0033] like Figure 3 , Figure 4 As shown, the air conditioner includes a compressor, a one-way valve, a solenoid four-way reversing valve, a gas-liquid separator, an outdoor heat exchanger, an indoor heat exchanger, expansion valve A, expansion valve B, a plate heat exchanger A, and a three-way valve. The compressor outlet is connected to the indoor heat exchanger via a pipeline to form a refrigerant circuit. When the air conditioner is in heating mode, the high-temperature and high-pressure refrigerant compressed by the compressor enters the indoor heat exchanger via a pipeline. The indoor heat exchanger exchanges heat between the refrigerant and the air inside the vehicle to achieve heating of the vehicle.

[0034] The refrigerant circuit of the air conditioner is connected to the water circuit through a heat exchanger. The water in the water circuit exchanges heat with the refrigerant in the refrigerant circuit through the heat exchanger. The driver's area radiator and the passenger area radiator are installed on the water circuit.

[0035] The heat exchanger is preferably a plate heat exchanger.

[0036] The water system includes a water pump, which drives the flow of water within the system.

[0037] Specifically, the water system includes an expansion tank, a water pump, and water pipes. The water pump is connected to the inlet of the expansion tank and drives the flow of water in the pipes. Both the water pipes and the air conditioning piping are connected to plate heat exchanger B. Through plate heat exchanger B, the water in the pipes exchanges heat with the refrigerant in the piping. After the heat exchange, the water temperature rises and enters the expansion tank for buffering. The buffered high-temperature water enters the driver's area radiator and the passenger area radiator, dissipating heat to the driver's area through the driver's area radiator and to the passenger area through the passenger area radiator. The water that has been cooled by the driver's area radiator and the passenger area radiator re-enters plate heat exchanger B through the water pipes for heat exchange.

[0038] Preferably, the air conditioning vents are located on the top of the vehicle;

[0039] The radiator vents in the driver's area are located at the bottom of the driver's area.

[0040] The air vents for the radiators in the passenger area are located at the bottom of the passenger area.

[0041] When the air conditioning and vehicle heating are controlled in a coordinated manner, the following is formed: Figure 6The airflow pattern shown indicates that the air conditioner dissipates heat from the top vents into the vehicle to ensure head comfort, while the radiators in the driver's and passenger's areas dissipate heat from the bottom of the vehicle to ensure foot comfort. This ensures that the interior temperature reaches the set value and achieves a balanced temperature throughout the vehicle, keeping the driver and passengers warm from head to toe, ultimately resulting in a comfortable riding experience.

[0042] The temperature acquisition module is used to acquire the temperature of the driver's area, the temperature of the passenger area, and the water temperature in the water circuit after heat exchange.

[0043] like Figure 7 , Figure 8 As shown, the temperature acquisition module includes a driver's area temperature sensor, a passenger area temperature acquisition module, and a water temperature sensor.

[0044] A driver's area temperature sensor is positioned in the driver's area to acquire the temperature. Preferably, the sensor is positioned 200mm in front of the driver's headrest. Figure 7 , Figure 8 Point #2 in the layout.

[0045] The passenger area temperature acquisition module includes multiple passenger area temperature sensors to acquire temperatures at various locations within the passenger area. The average of these temperatures is then used to obtain the passenger area temperature. If one or more passenger area temperature sensors fail, the average of the temperatures acquired by the remaining, functioning sensors is used to obtain the final passenger area temperature.

[0046] Preferably, passenger area temperature sensors are installed at the air conditioning vents, return air vents, and at different locations before, after, and above / below the aisle. Figure 7 , Figure 8 In the middle section, point #3 is placed 100mm below the center of the return air vent to obtain the return air temperature. Point #4 is placed at the air outlet closest to the return air temperature point to obtain the air outlet temperature. Three additional points are placed along the front (1500mm from the front windshield), middle, and rear (1500mm from the rear windshield) directions of the passage. Each point has four points arranged from top to bottom: 200mm from the roof (top), 700mm (head), 1000mm (waist), and 300mm from the floor (feet). The points arranged from top to bottom at the front, middle, and rear are #5-8, #9-12, and #13-16, respectively, to obtain the temperature at different locations within the passage.

[0047] A water temperature sensor is used to obtain the water temperature in the water circuit after heat exchange by the heat exchanger.

[0048] In addition, the temperature acquisition module is also used to obtain the temperature of the indoor heat exchanger core.

[0049] There are no other objects within 100mm of the temperature sensor, and no airflow with a large temperature difference passes through it.

[0050] In this embodiment, to achieve coordinated control of the air conditioning and heating, the controller uses the acquired temperatures of the driver's area, passenger area, and the water temperature in the water circuit after heat exchange to coordinate the control of the air conditioning, driver's area radiator, and passenger area radiator. The ultimate goal of this coordinated control is to achieve the set temperature inside the vehicle and to achieve temperature balance throughout the three-dimensional space. The fan speed is adjusted from high speed for rapid heating to low speed for even, gentle heat delivery, ensuring that the driver and passengers are kept warm from head to toe, ultimately achieving a comfortable riding experience.

[0051] The controller is used to control the radiator fan in a certain area to operate at low speed when the air conditioning is in heating mode, the driver's area radiator fan, and the passenger area radiator fan are turned on, and the temperature in a certain area is less than or equal to a first set value for that area, while the water temperature in the water circuit is greater than a first temperature value; when the temperature in a certain area is less than or equal to the first set value for that area, while the water temperature in the water circuit is greater than a second temperature value, the controller controls the radiator fan in that area to operate at high speed; when the temperature in a certain area is greater than the first set value but less than or equal to the second set value for that area, the controller keeps the radiator fan in that area operating at a constant speed; and when the temperature in a certain area is greater than the second set value for that area, the controller turns off the radiator fan in that area.

[0052] The controller is also used to control the driver's area radiator to start working at low speed when the water temperature in the water circuit is greater than a first temperature value after the air conditioning heating is turned on, and to control the passenger area radiator to start working at low speed when the temperature in the driver's area is higher than a third set value.

[0053] The controller is also used to activate the water pump in the water circuit when the temperature of the indoor heat exchanger core exceeds the fourth set value after the air conditioner is turned on for heating.

[0054] The controller is also used to control the driver's area radiator to operate at a low speed when the driver's area temperature sensor fails, and to control the passenger area radiator to operate at a low speed when all passenger area temperature sensors fail.

[0055] The first and second settings for the passenger area may be the same as or different from the first and second settings for the driver area.

[0056] In practice, a vehicle heating control panel is set up. After the vehicle enters the heating mode through the control panel and the water pump starts working, the linkage control starts and the linkage control icon is constantly lit. When the water pump stops working, the linkage control ends and the linkage control icon flashes.

[0057] The fourth setting is preferably 27°C, and the third setting is preferably 15°C.

[0058] After the vehicle enters heating mode, the controller starts the air conditioner. Then, it acquires the temperature of the indoor heat exchanger core. When the temperature of the indoor heat exchanger core is >27°C, the water pump turns on, and the water in the water pipes begins to exchange heat with the refrigerant in the refrigerant circuit through the heat exchanger. After that, it begins to acquire the temperature of the driver's area, the temperature of the passenger area, and the water temperature in the water circuit after heat exchange through the heat exchanger.

[0059] When the water temperature in the water circuit after heat exchange is detected to be greater than the first temperature value S1, the driver's area radiator is controlled to start working at low speed. When the driver's area temperature Tps > 15℃, the passenger area radiator is controlled to start working at low speed.

[0060] When the air conditioning is in heating mode, and the radiator fans in the driver's area and passenger area are all turned on, the radiator in the driver's area is controlled according to the temperature in the driver's area and the water temperature in the water circuit after heat exchange. Specifically:

[0061] As shown in Table 1, when the temperature Tps in the driving area is less than or equal to the first set value of the driving area, and the water temperature in the water circuit is greater than the first temperature value S1, the radiator fan in the driving area is controlled to start at low speed; when the temperature in the driving area is less than or equal to the first set value of the driving area, and the water temperature in the water circuit is greater than the second temperature value S2, the radiator fan in the driving area is controlled to start at high speed; when the temperature in the driving area is greater than the first set value of the driving area but less than or equal to the second set value of the driving area, the radiator fan in the driving area is controlled to maintain its operating state, that is, if it is currently in high speed mode, it will continue in high speed mode, and if it is currently in low speed mode, it will continue in low speed mode; when the temperature in the driving area is greater than the second set value of the area, the radiator fan in that area is controlled to turn off; when the driving area temperature sensor malfunctions, the radiator in the driving area is controlled to start at low speed.

[0062] As shown in Table 2, the passenger area radiator is controlled based on the passenger area temperature and the water temperature in the water circuit after heat exchange, specifically as follows:

[0063] When the passenger area temperature Tpc is less than or equal to the first set value of the passenger area, and the water temperature in the water circuit is greater than the first temperature value S1, the passenger area radiator fan is controlled to start at low speed; when the passenger area temperature is less than or equal to the first set value of the passenger area, and the water temperature in the water circuit is greater than the second temperature value S2, the passenger area radiator fan is controlled to start at high speed; when the passenger area temperature is greater than the first set value of the passenger area but less than or equal to the second set value of the passenger area, the passenger area radiator fan's operating state remains unchanged, that is, if it is currently in high speed mode, it continues in high speed mode, and if it is currently in low speed mode, it continues in low speed mode; when the passenger area temperature is greater than the second set value of the area, the passenger area radiator fan is controlled to shut down; when all passenger area temperature sensors are faulty, the passenger area radiator is controlled to start at low speed.

[0064] The first setting for the driver's area is dH-1℃, and the second setting is dH+1℃; the first setting for the passenger area is hH-1℃, and the second setting is hH+1℃. Here, dH and hH are the temperatures set as needed via the vehicle's heating control panel.
