The memory 1005 may also be a storage device independent of the aforementioned processor 1001.
[0044] Those skilled in the art will understand that Figure 1 The structure shown in the figure does not constitute a limitation on the vehicle air conditioning system, and may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.
[0045] like Figure 1 As shown, the memory 1005 as a storage medium may include an operating system, a data storage module, a network communication module, a user interface module, and a vehicle air conditioning system control program. Figure 1 In the vehicle air-conditioning system shown, the network interface 1004 is mainly used for data communication with other devices; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and the memory 1005 in the vehicle air-conditioning system of the present invention can be set in the vehicle air-conditioning system, and the vehicle air-conditioning system calls the vehicle air-conditioning system control program stored in the memory 1005 through the processor 1001, and executes the control method of the vehicle air-conditioning system provided by the embodiment of the present invention.
[0046] Please refer to Figures 3 to 9 In an embodiment of the present invention, the vehicle air conditioning system includes a vehicle air conditioner, an air duct assembly connected to the vehicle air conditioner, and an air outlet connected to the air duct assembly. The vehicle body 10 has a passenger compartment. The air outlet includes an interior air supply outlet provided in the passenger compartment. The air duct assembly includes an interior air supply duct 22. The interior air supply duct 22 is connected between the interior air supply outlet and the vehicle air conditioner, so that the air flow generated by the vehicle air conditioner passes through the interior air supply duct 22 and the interior air supply outlet, flows into the passenger compartment and adjusts the temperature in the passenger compartment.
[0047] Specifically, an MVP (Multi-Purpose Vehicle) model with three rows of seats is used as an example for explanation. The vehicle body 10 includes a body A-pillar 10a, a body B-pillar 10b, a body C-pillar 10c, and a body floor. The front seats, the rear seats, and the three-row seats are arranged in sequence in the passenger compartment from the front to the rear (i.e., from the front to the rear). The air outlets in the passenger compartment include the air outlets on the instrument panel (i.e., the air outlets on the instrument panel, which are usually used for blowing the front seats), the air outlets on the auxiliary instrument panel (i.e., the air outlets on the auxiliary instrument panel 111). , usually used for the rear row blowing surface), the air outlet on the front door trim (i.e. the front door air outlet, usually used for defoggering the window glass), the air outlet on the B-pillar interior panel (i.e. the B-pillar air outlet, usually used for the rear row blowing surface), the air outlet on the C-pillar interior panel (i.e. the C-pillar air outlet, usually used for the three-row blowing surface), the air outlet on the ceiling (i.e. the ceiling air outlet, usually used for the rear row blowing surface or the three-row blowing surface), the air outlet of the front row foot blowing air duct, and the air outlet of the rear row foot blowing air duct 223 (usually used for the rear row foot blowing), etc. Correspondingly, a B-pillar air duct is provided in the B-pillar 10b of the vehicle body, and the B-pillar air duct is connected between the B-pillar air outlet and the vehicle-mounted air conditioner; a C-pillar air duct is provided in the C-pillar 10c of the vehicle body, and the C-pillar air duct is connected between the C-pillar air outlet and the vehicle-mounted air conditioner; a ceiling air duct is provided on the top of the passenger compartment, and the ceiling air duct is connected between the ceiling air outlet and the vehicle-mounted air conditioner. Of course, it is easy to understand that the structural configuration of the above-mentioned internal air outlet and the internal air duct 22 is not limited to the MVP model, but can also be a sedan, an off-road vehicle or a pickup truck model.
[0048] In one embodiment, a special external air outlet 21 is provided on the outer side of the vehicle body 10, and the external air outlet 21 can be used to blow air out of the vehicle. Figures 3 to 6In one embodiment, the air outlet on the vehicle body 10 further includes an external air outlet 21, which is arranged on the outer side of the vehicle body 10, and the air duct assembly further includes an external air duct 23, which is connected between the external air outlet 21 and the vehicle air conditioner. It should be noted that the outer side of the vehicle body 10 includes the outer side of components such as body sheet metal parts, body opening and closing parts, and exterior trims, such as side panels, front door panels, C-pillar exterior trims, or the rear bucket 10d (i.e., cargo bucket) of a pickup truck, etc., that is, the external air outlet 21 can be arranged on any of the above-mentioned components that can be exposed on the outside of the vehicle body 10, so as to guide the airflow sent by the external air duct 23 to the space outside the vehicle. In this way, the user can further use the ventilation pipe to connect one end of the ventilation pipe to the external air outlet 21, and the other end to the closed place or directly extend into the closed place, so as to guide the airflow generated by the vehicle air conditioner into the closed place, so as to achieve ventilation, cooling or heating of the closed place. Specifically, the ventilation pipe can be fixed on the external air supply port 21 in a telescopic or foldable manner, or can be detachably connected to the external air supply port 21.
[0049] It should be noted that a closed place refers to a shelter located outdoors that can provide shelter, such as a tent, a bamboo house, a cabin, a container, etc. When a user drives outdoors and encounters or builds a closed place by himself, he can use it as an activity space to move around or rest inside. At this time, using the car air conditioner to blow air into the closed place can make the users staying in the closed place more comfortable.
[0050] Please refer to Figure 3 and 4 In some embodiments, the external air duct 23 is connected to the internal air duct 22, that is, the existing internal air duct 22 structure is used as a part of the external air duct 23. In other words, the external air duct 23 is used as a new branch pipe of the internal air duct 22. In this way, the structure of the air duct assembly can be simplified, thereby reducing the manufacturing cost and overall weight of the vehicle. Of course, in other embodiments, an independent external air duct 23 structure can be specially configured for the external air outlet 21, and the external air duct 23 is directly connected to the vehicle air conditioner without using the existing internal air duct 22 as a part of its air flow path.
[0051] Without loss of generality, the instrument panel air outlet usually includes a front row side air outlet and a front row central air outlet. The front row side air outlet is usually provided with two and is respectively provided on the main driving side and the co-pilot side; the front row central air outlet is usually provided between the main driving side and the co-pilot side. The vehicle air conditioner is usually provided in the instrument panel, and the internal air duct 22 includes a front row blowing face air duct 221 provided in the instrument panel, and the front row blowing face air duct 221 includes a side blowing face air duct 221a and a central blowing face air duct 221b. The side blowing face air duct 221a is connected between the front row side air outlet and the vehicle air conditioner, and the central blowing face air duct 221b is connected between the front row central air outlet and the vehicle air conditioner. The auxiliary instrument panel air outlet 111 is usually provided on the rear end cover of the auxiliary instrument panel, and the internal air duct 22 includes a rear row blowing face air duct provided in the auxiliary instrument panel, and the rear row blowing face air duct is connected between the auxiliary instrument panel air outlet 111 and the vehicle air conditioner.
[0052] It is understandable that there are many options for arranging the external air outlet 21, for example, it can be arranged on the front end surface of the body A pillar 10a, the body B pillar 10b, the body C pillar 10c, the pickup truck rear box 10d, etc. Figure 3 and 4 In the embodiment where the vehicle is equipped with a side blowing surface air duct 221a, the external air outlet 21 is provided at the A-pillar 10a of the vehicle body, and the external air duct 23 is connected to the side blowing surface air duct 221a. Figure 4 As shown, the external air duct 23 is connected to one end of the side blowing surface air duct 221a close to the front side air outlet, and the external air outlet 21 is arranged at a position of the A-pillar 10a of the vehicle body close to the front side air outlet. In this way, the length of the external air duct 23 can be shortened, which is beneficial to simplify the structure of the air duct assembly and reduce the negative impact of the external air duct 23 on the layout of the internal parts of the instrument panel.
[0053] Please refer to Figure 3 and 4 In the embodiment where the vehicle is equipped with a rear-row face-blowing air duct and / or a rear-row foot-blowing air duct 223, the external air vent 21 is arranged at the lower side edge of the vehicle body B-pillar 10b, and the external air duct 23 is connected to the rear-row foot-blowing air duct 223 or the rear-row face-blowing air duct. That is, the external air duct 23 extends along the left-right direction of the vehicle body 10, which is conducive to shortening the length dimension of the external air duct 23. It should be noted that, without loss of generality, the vehicle body B-pillar 10b is usually blocked by the closed front door and rear door, so if the external air vent 21 is arranged on the vehicle body B-pillar 10b, the front door and / or rear door can be opened to expose the external air vent 21; or a avoidance opening can be arranged on the front door and / or rear door corresponding to the external air vent 21, so that the external air vent 21 can also be exposed when the front door and rear door are both closed.
[0054] By analogy, if the vehicle is equipped with a B-pillar air outlet and a B-pillar air duct, the external air outlet 21 provided on the B-pillar 10b of the vehicle body can be directly connected to the B-pillar air duct; if the vehicle is equipped with a roof air outlet and a roof air duct, the external air outlet 21 provided on the B-pillar 10b of the vehicle body can be directly connected to the ceiling air duct; if the vehicle is equipped with a C-pillar air outlet and a C-pillar air duct, the external air outlet 21 provided on the C-pillar 10c of the vehicle body can be directly connected to the C-pillar air duct.
[0055] Of course, please refer to Figure 3 In the embodiment of the present invention, at least two external air outlets 21 may be provided, for example, one external air outlet 21 is provided on the A-pillar 10a of the vehicle body, and one external air outlet 21 is provided on the B-pillar 10b of the vehicle body. Optionally, in this embodiment, except for the ventilation pipe being used and its external air outlet being in an open state, the remaining external air outlets and all internal air outlets may be automatically closed by the control of the vehicle air conditioning system, for example, an electric damper may be provided on the internal air outlet, the internal air duct, the external air outlet, the external air duct or the blower, so as to selectively enable individual or all of the internal air outlets to be automatically opened and closed. In this way, most of the airflow of the vehicle air conditioner can flow to the enclosed place, thereby increasing the flow rate flowing into the enclosed place and improving the blowing effect.
[0056] To improve the convenience of using the car's outdoor air blowing function, please refer to Figure 5 and 6 In the embodiment where the vehicle is provided with an external air outlet 21, the external air outlet 21 optionally includes a connecting installation cavity section 21a and a storage cavity section 21b, the storage cavity section 21b is connected to the outside of the vehicle, and the outer end 30b of the external air duct 23 is arranged at the installation cavity section 21a; the vehicle air conditioning system also includes a ventilation pipe 30, the ventilation pipe 30 has an inner end 30a and an outer end 30b, the inner end 30a of the ventilation pipe 30 is connected to the outer end 30b of the external air duct 23, and the ventilation pipe 30 has a storage state and a use state. In the storage state, the ventilation pipe 30 can be stored in the storage cavity section 21b; in the use state, the outer end 30b of the ventilation pipe 30 extends out of the storage cavity section 21b and is connected to the closed place. In this way, the vehicle has its own ventilation pipe 30, which can facilitate users to direct the airflow generated by the vehicle air conditioner to a farther or higher area, thereby improving the use effect and flexibility of the vehicle's outdoor blowing function. Of course, in other embodiments, the ventilation duct 30 can be detachably connected to the outer end 30b of the external air duct 23, or the ventilation duct 30 can be detachably connected to the external air outlet 21; in this way, when the ventilation duct 30 is not needed, the ventilation duct 30 can be removed and stored separately, thereby simplifying the structure of the external air outlet 21.
[0057] In order to protect the external air duct 23 and the external air outlet 21, please refer to Figure 5 and 6In one embodiment, the vehicle further includes a cover plate 40, which is movably connected to the storage cavity section 21b to cover or reveal the storage cavity section 21b. In this way, the flatness of the vehicle's exterior shape can be maintained, and the external air duct 23 and the external air outlet 21 can be protected to prevent dust. Of course, in other embodiments, the vehicle may also include a cover plate, which may be detachably mounted on the outer end 30b of the external air duct 23 by means of snap connection or screw connection. In one embodiment, one side of the cover plate 40 is rotatably connected to the storage cavity section 21b, and the other side is snap-connected to the storage cavity section 21b. Of course, in some embodiments, the cover plate 40 may be provided with an external threaded cylindrical surface on one side facing the storage cavity section 21b, and the inner wall surface of the storage cavity section 21b may be provided with an adapted threaded hole section corresponding to the external threaded cylindrical surface, that is, the cover plate 40 is threadedly connected to the storage cavity section 21b. In other embodiments, the cover plate 40 is slidably connected to the storage cavity section 21b, for example, referring to the movable roller shutter structure of the storage box on the auxiliary instrument panel, or referring to the sliding cover structure on the sun visor inside the car for covering the makeup mirror.
[0058] Please refer to Fig. 9 In the embodiment where the ventilation duct 30 can be disassembled, optionally, the inner end 30a of the ventilation duct 30 is provided with a first magnetic attraction portion 33, and the external air outlet 21, the external air duct 23 or the internal air outlet is provided with a second magnetic attraction portion 112, and the first magnetic attraction portion 33 can be magnetically fixed on the second magnetic attraction portion 112. Specifically, at least one of the first magnetic attraction portion 33 and the second magnetic attraction portion 112 is configured as a magnet, and the other can be a magnetic metal. In this way, the installation and removal of the ventilation duct 30 are facilitated. For example, please refer to Fig. 9 Four magnetic metal blocks are arranged around the air outlet 111 of the auxiliary instrument panel, and a ring magnet is arranged on the inner end 30a of the ventilation pipe 30. Of course, in other embodiments, the inner end 30a of the ventilation pipe 30 can also be installed on the external air outlet 21, the external air duct 23 or the internal air outlet through a clamping structure, screws or Velcro.
[0059] The telescopic structure of the ventilation pipe 30 has various forms, for example, please refer to Figure 6 and 9In one embodiment, the ventilation duct 30 is provided with a telescopic structure, which includes a telescopic hose 31 and a plurality of support frames 32 provided on the telescopic hose 31, and the plurality of support frames 32 are distributed at intervals along the extension direction of the telescopic hose 31. In this way, the support frames 32 can not only keep the telescopic hose 31 in a certain shape, but also facilitate the folding and storage of the telescopic hose 31, and the telescopic hose 31 can also change the overall extension direction of the ventilation duct 30. Of course, in some embodiments, the ventilation duct 30 can also include a plurality of pipe sections, and two adjacent pipe sections can slide and retract relative to each other, thereby changing their lengths. In other embodiments, the ventilation duct 30 can also be configured as a hose, such as a canvas hose, a PVC (Polyvinyl Chloride) leather hose, etc., which can be folded and stored in the storage cavity section 21b.
[0060] In one embodiment, the material of the telescopic hose 31 is one of canvas, PVC leather, PU (polyurethane) leather and aluminum foil. Optionally, the canvas is waterproof canvas, which is suitable for rainy and snowy weather and has the advantages of being scratch-resistant, wear-resistant and low-cost.
[0061] Of course, the vehicle may not be provided with a dedicated external air duct 23 and external air outlet 21, but may use a ventilation pipe connected to the internal air outlet to guide the airflow generated by the vehicle air conditioner to a closed place outside the vehicle. Figures 7 to 9 In another embodiment of the present invention, the vehicle air conditioning system further includes a ventilation pipe 30, the ventilation pipe 30 having an inner end 30a and an outer end 30b, and the inner end 30a of the ventilation pipe 30 can be detachably connected to an inner air outlet (e.g. Fig. 9 The auxiliary instrument air outlet 111 in the vehicle), the outer end 30b of the ventilation pipe 30 can extend out of the passenger compartment and communicate with the enclosed place. In this way, the user can use the ventilation pipe 30 that is easy to disassemble and assemble to connect to the internal air outlet to guide the airflow generated by the vehicle air conditioner to the enclosed place, which can simplify the structure of the vehicle and improve the comfort and convenience of the user in the enclosed place. In this embodiment, optionally, except for the internal air outlet connected to the ventilation pipe in an open state, the other internal air outlets can be automatically closed under the control of the vehicle air conditioning system, so that most of the airflow of the vehicle air conditioner can flow to the enclosed place, thereby increasing the flow rate flowing into the enclosed place and improving the blowing effect.
[0062] In one embodiment, the vehicle air conditioner includes a cooling module, a heating module and a blower, wherein the cooling module includes a compressor, a condenser connected to the compressor, an evaporator connected to the compressor, an expansion valve connected to the compressor, and a heat dissipation fan for blowing air to the condenser, and the heating module includes an electric heater, a water channel, a water pump connected to the water channel, a warm air core connected to the water channel, and a three-way valve connected to the water channel, the water channel is used for the circulation of coolant and is at least partially arranged on the engine to use the heat generated when the engine is working to increase the temperature; the airflow generated by the blower when working can exchange heat with the evaporator or the warm air core, and then output to the passenger compartment of the vehicle. Specifically, the refrigeration principle of the vehicle air conditioner is: the refrigerant is compressed into a high-temperature and high-pressure gas by the compressor, and becomes a high-temperature and high-pressure liquid after heat dissipation in the condenser, and then flows into the evaporator after throttling by the expansion valve and absorbs heat to become a low-temperature and low-pressure gas, and then returns to the compressor for the next cycle, and the airflow generated by the blower in this process is cooled when passing through the evaporator. The heating principle of the vehicle air conditioner is as follows: in the first mode, when the engine coolant temperature is sufficient, the coolant is directly sent to the heater core through the water pump and then returns to the water pump, so that the airflow generated by the blower can be heated when passing through the heater core; in the second mode, when the engine coolant temperature is too low, the three-way valve adjusts the direction of the coolant so that the coolant passes through the water pump, the electric heater and the heater core in sequence, and then returns to the water pump, wherein the electric heater is used to heat the coolant in the water circuit.
[0063] Of course, in other embodiments, the cooling module and heating module of the vehicle air conditioner may also be other structural forms, such as semiconductor cooling and heating structural forms. Since the relevant technologies are relatively mature, they will not be described one by one here.
[0064] In one embodiment, the vehicle air conditioning system of the present invention further includes an inlet temperature sensor, an outlet temperature sensor, and a sunlight sensor. The sunlight sensor is usually arranged on the dashboard and below the front windshield, and is used to detect the intensity of solar radiation. The inlet temperature sensor is used to detect the inlet temperature of the vehicle air conditioner (i.e., the outside air temperature), and the outlet temperature sensor is used to detect the outlet temperature of the vehicle air conditioner. For example, the inlet temperature sensor can be arranged in the air inlet of the vehicle air conditioner, and the outlet temperature sensor can be arranged in the air outlet of the vehicle air conditioner or on the evaporator.
[0065] The present invention also provides a vehicle air conditioning system control method, which is used for a vehicle air conditioning system of a vehicle, and the vehicle air conditioning system can supply air to a closed place outside the vehicle. For the convenience of the text, the following will take a tent as an example of a closed place for explanation. Figure 2 In the first embodiment of the vehicle air conditioning system control method of the present invention, the vehicle air conditioning system control method includes step S10, step S20, step S30 and step S40.
[0066] Step S10: Acquire the temperature inside the closed place outside the vehicle.
[0067] In this embodiment, the temperature in the tent refers to the actual temperature data that changes with the environment and time, rather than the temperature data of a preset constant value. Only in this way can the vehicle air conditioning system be supported to implement the subsequent closed-loop control steps of the temperature in the tent. Specifically, in this embodiment, the temperature in the tent can be obtained by direct measurement, or by indirectly measuring other parameters and substituting them into the heat balance formula to calculate the temperature in the tent. For example, in an embodiment where a temperature sensor is provided in the tent, the vehicle air conditioning system can use the Internet of Things to achieve wireless communication with the temperature sensor and obtain real-time data from the temperature sensor.
[0068] Step S20: Obtaining the set temperature of the vehicle air conditioning system in the vehicle exterior air supply mode.
[0069] In this embodiment, when the vehicle air conditioning system receives the external air supply start signal, it will be controlled to enter the vehicle external air supply mode, so that the airflow generated by the vehicle air conditioner can be introduced into the tent outside the vehicle through the air duct assembly, the air outlet and the ventilation pipe, so as to realize cooling, heating or blowing the internal space of the tent. Through the specially set vehicle external air supply mode, the vehicle air conditioning system can automatically enter the vehicle external air supply mode after receiving the external air supply start signal to realize the vehicle external blowing function, and it is flexible to use and suitable for a variety of closed places, thereby improving the comfort and convenience of outdoor activities. In addition, using the vehicle air conditioner to replace the independent portable outdoor air conditioner can save the purchase cost and maintenance cost of the portable outdoor air conditioner, and the vehicle external air supply device itself has a simple structure and low production cost, so that users can experience the effect of air conditioning function outdoors at a lower cost.
[0070] Specifically, there are many ways to get the signal to start the outside air supply. For example, the user can operate the vehicle's central control screen, input voice commands, or operate an application on a mobile phone or tablet to send a remote command to the vehicle to start the outside air blowing function (that is, control the vehicle air conditioning system to enter the outside air supply mode). The processor of the vehicle air conditioning system will receive these signals to start the outside air supply function. Of course, the user can also set the scheduled start time to start the outside air blowing function at a scheduled time.
[0071] In this embodiment, the set temperature is an ideal temperature, which can be a default temperature value set by the vehicle air conditioning system when it leaves the factory, or a temperature value stored by the vehicle air conditioning system when the vehicle outdoor air supply mode is last exited, or a temperature value adjusted by the user according to changes in demand. Specifically, the user can adjust the set temperature by operating the vehicle central control screen, inputting voice commands, or operating an application on a mobile phone or tablet computer to control the vehicle air conditioning system to work according to the set temperature.
[0072] Step S30: Compare the temperature in the field with the set temperature and obtain a comparison result.
[0073] Specifically, comparing the temperature inside the tent with the set temperature is essentially comparing the actual temperature inside the tent with the ideal temperature. Then, through closed-loop control of the temperature inside the tent, the temperature inside the tent can be kept as close to the ideal temperature range as possible, thereby improving the comfort of the user. In particular, when the user rests overnight in an outdoor tent, the outdoor ambient temperature drops significantly at night. If the vehicle air conditioning system only works under constant working conditions, the temperature inside the tent will exceed the comfortable temperature range and make the user feel uncomfortable, such as cold.
[0074] Step S40: adjusting the operating conditions of the vehicle air conditioning system according to the comparison result.
[0075] Specifically, when the vehicle air conditioning system is in cooling mode, if the temperature in the venue is lower than the set temperature, it means that the actual temperature in the tent is too low, and the cooling output of the vehicle air conditioning system needs to be reduced; if the temperature in the venue is higher than the set temperature, it means that the actual temperature in the tent is too high, and the cooling output of the vehicle air conditioning system needs to be increased. When the vehicle air conditioning system is in heating mode, if the temperature in the venue is lower than the set temperature, it means that the actual temperature in the tent is too low, and the heating output of the vehicle air conditioning system needs to be increased; if the temperature in the venue is higher than the set temperature, it means that the actual temperature in the tent is too high, and the heating output of the vehicle air conditioning system needs to be reduced.
[0076] Optionally, in this embodiment, the step of adjusting the working condition of the vehicle air-conditioning system according to the comparison result includes: adjusting the air outlet temperature and / or air volume of the vehicle air-conditioning system. It should be noted that the air outlet temperature refers to the air temperature at the air outlet of the vehicle air conditioner, and the air outlet volume refers to the air flow rate (i.e., mass flow rate) at the air outlet of the vehicle air conditioner. For example, in the cooling mode, the power of the compressor is adjusted to adjust the evaporator temperature, thereby adjusting the air outlet temperature; or, the speed of the blower or the opening of the electric damper is adjusted to adjust the air outlet volume.
[0077] In the technical solution of the present invention, when the vehicle air conditioning system enters the outdoor air supply mode, the ventilation pipe connected between the vehicle and the tent can guide the airflow generated by the vehicle air conditioner into the tent to achieve ventilation, cooling or heating of the tent, so that the user in the tent can experience a more comfortable temperature environment, thereby improving the user's outdoor experience. Secondly, by obtaining the temperature in the tent and comparing it with the set temperature, and then adjusting the working conditions of the vehicle air conditioning system according to the comparison result, the temperature in the tent can be kept within the ideal range as much as possible, that is, closed-loop control of the temperature in the tent is achieved, thereby improving the user's comfort. Specifically, in the technical solution of the present invention, the temperature in the tent can be directly obtained by measuring with a temperature sensor installed in the tent, or it can be indirectly obtained by calculation.
[0078] In the second embodiment of the vehicle air conditioning system control method of the present invention, based on the first embodiment of the vehicle air conditioning system control method, step S10 includes step S11, step S12 and step S13.
[0079] Step S11: Obtaining vehicle air conditioner performance Q b .
[0080] Specifically, the performance of the car air conditioner Q b Including cooling performance and heating performance, in this embodiment, the vehicle air conditioner performance Q is optionally calculated using the air enthalpy difference method b , that is, the performance of the car air conditioner Q b The calculation formula is: b =q v *(h i -h o ), where q v It is the mass flow rate of the car air conditioner, which refers to the total flow rate of the car air conditioner, and the unit is kg / h, i.e. kilograms per hour; h i is the enthalpy value of the air inlet of the vehicle air conditioner, h o is the enthalpy value of the air outlet of the vehicle air conditioner, h i and h o The unit is kj / kg, that is, kilojoule / kilogram.
[0081] Without loss of generality, the mass flow rate q of the vehicle air conditioner is v Usually it is related to its circulation mode, set temperature and blower speed. In theory, it is a matrix table. The accuracy of the matrix table depends on the calibration of the vehicle air conditioner under the vehicle state. Of course, if the mass flow rate q v The numerical accuracy requirement of is not high, and it can also be set to be linearly related to the blower speed. That is, in this embodiment, the mass flow rate q corresponding to the working condition can be directly obtained according to the blower speed. vIn this way, the number of calculation steps and the calculation time of the processor can be reduced. Of course, in other embodiments, the actual data such as the circulation mode (internal circulation or external circulation), the set temperature and the blower speed of the vehicle air conditioner can be obtained at the same time, and the accurate actual mass flow rate q can be obtained according to the matrix table. v .
[0082] Of course, in other embodiments, other methods can be used to obtain the vehicle air conditioner performance Q b For example, when calibrating a car air conditioner, the matrix table also records the corresponding data of the car air conditioner performance. Then, in actual application, the car air conditioner performance Q under the corresponding working conditions can be directly obtained according to the matrix table. b Actual data is obtained without the need for calculation using the enthalpy difference method.
[0083] In this embodiment, the enthalpy value h of the air inlet of the vehicle air conditioner is i The corresponding enthalpy value can be obtained by obtaining the temperature and humidity data of the air in the air inlet, that is, the air inlet temperature and air inlet humidity, and looking up the air enthalpy diagram, where the air enthalpy diagram can be pre-stored in the memory of the vehicle air conditioning system. Similarly, the enthalpy value h of the air outlet of the vehicle air conditioner o The temperature and humidity data of the air in the air outlet, i.e., the outlet temperature and the outlet humidity, can be obtained by looking up the air enthalpy and humidity chart to obtain the corresponding enthalpy value. Among them, the inlet humidity and the outlet humidity can use the factory default values, for example, the default inlet humidity and the outlet humidity of the vehicle air conditioner are both 50%; the temperature data is obtained through the temperature sensor, specifically including the inlet temperature sensor and the outlet temperature sensor, the inlet temperature sensor is used to detect the inlet temperature (i.e., the temperature outside the vehicle), and the outlet temperature sensor is used to detect the outlet temperature, for example, the inlet temperature sensor can be set in the air inlet of the vehicle air conditioner, and the outlet temperature sensor can be set in the air outlet of the vehicle air conditioner or on the evaporator. Of course, in other embodiments, the inlet humidity and the outlet humidity can be obtained respectively by two humidity sensors arranged in the air inlet and the air outlet; or a humidity sensor can be arranged in the air outlet to obtain the outlet humidity, and at the same time, the Internet or the Internet of Things, that is, mobile communication modules such as 4G / 5G, or wireless communication modules such as Bluetooth modules are used to indirectly obtain the outdoor air humidity from other information channels. For example, weather forecast information of the city / region to which the location belongs is obtained based on the positioning information of the vehicle, wherein the weather forecast information includes outdoor air humidity, and the outdoor air humidity is used as the inlet humidity.
[0084] Specifically, when the vehicle air conditioner is in cooling mode, the air outlet temperature T 2= evaporator temperature + 5°C, that is, when the outlet air temperature sensor is installed on the evaporator and measures the evaporator temperature, 5°C is added to the evaporator temperature as the outlet air temperature; when the vehicle air conditioner is in heating mode, the outlet air temperature T 2 = outside air temperature (i.e. air inlet temperature) + 30°C, that is, when the air inlet temperature sensor measures the outside air temperature, 30°C is added to the outside air temperature as the air outlet temperature; when the vehicle air conditioner is only used for ventilation (i.e. no cooling or heating), the air outlet temperature T 2 = Evaporator temperature, that is, the evaporator temperature is directly used as the outlet air temperature. Inlet air temperature T 1 =Outside air temperature = Ambient air temperature T h .
[0085] Step S12: Obtain the heat load Q of the enclosed space a ;in, T is an unknown number representing the temperature in the field.
[0086] In this embodiment, the heat load Q of the enclosed space a The calculation formula is: a =Q 2 +Q 3 +Q 4 +Q 5 ; Among them, Q 2 is the solar radiation heat, expressed as the radiation heat load absorbed by the enclosed space; Q 3 Q is the heat conduction of the place, which is expressed as the heat load caused by the heat from the outside of the closed place being conducted to the inside; 4 Q is the fresh air load, which is the heat load caused by the outside air of a closed place entering the inside through ventilation windows, holes or gaps; 5 is the heat dissipation of living organisms, expressed as the heat dissipation of all living organisms in a closed place; solar radiation heat Q 2 、The heat conduction of the place Q 3 , Fresh air load Q 4 , and the heat dissipation of the living body Q 5 At least one of them contains the unknown field temperature T.
[0087] Specifically, in this embodiment, the solar radiation heat Q 2 The calculation formula is: 2 =(η+ρ*a n / a w )*J*C 2 ; where η is the solar penetration coefficient of the enclosed space; ρ is the solar radiation absorption coefficient of the enclosed space; a n is the heat transfer coefficient of the outer surface of the enclosed space, a w It is the heat transfer coefficient of the inner surface of the closed place, and the unit is W / (m2 ·K), which is Watt / (square meter·Kelvin); J is the solar radiation in a closed place; C 2 It is the shading correction factor for enclosed places.
[0088] Without loss of generality, the outer tent fabrics of mainstream tents on the market are usually nylon, polyester, Oxford and sephora, etc., and the inner tent fabrics are usually nylon silk, Oxford and cotton, etc. Optionally, the solar penetration coefficient η of the tent is in the range of 0.1≤η≤0.5, for example, η=0.1; the solar radiation absorption coefficient ρ of the tent is in the range of 0.1≤ρ<1, for example, ρ=0.5; the outer surface heat transfer coefficient a of the tent is n The value range is 10W / (m 2 ·K)≤a n ≤20W / (m 2 ·K), for example, take a n =15W / (m 2 ·K); the heat transfer coefficient of the inner surface of the tent a w The value range is 15W / (m 2 ·K)≤a w ≤35W / (m 2 ·K), for example, take a w =25W / (m 2 ·K); tent sunshade correction factor C 2 The value range is 0.5≤C 2 ≤1.5, for example, C 2 =1.
[0089] Further optionally, the calculation formula of solar radiation J is: J = B*S f ; Where B is the solar radiation intensity, in W / m 2 , that is, watts / square meter; S f is the irradiated area of the enclosed place, in m 2 , i.e. square meters. Without loss of generality, the vehicle is usually equipped with a sunlight sensor, which is usually arranged on the dashboard and below the front windshield, and is used to detect the intensity of solar radiation. Considering that the vehicle is usually parked not far from the tent, the solar radiation intensity of the environment in which the tent and the vehicle are located is basically the same, so the solar radiation intensity B of the tent can directly refer to the data measured by the sunlight sensor on the vehicle. Of course, in other embodiments, the vehicle air-conditioning system can also use the Internet or the Internet of Things to indirectly obtain the solar radiation intensity received by the tent from other information channels, such as obtaining weather forecast information of the city / region to which the location belongs based on the positioning information of the vehicle, wherein the weather forecast information includes solar radiation intensity information, and the solar radiation intensity information is used as the solar radiation intensity B of the tent.
[0090] Irradiated area Sf There are many ways to obtain S. For example, in one embodiment, the user inputs the size or type of the tent, and the vehicle air conditioning system obtains the total exposed area S of the tent under the type and size accordingly. b For example, the total exposed area of a two-person hexagonal tent is S b Set to 8m 2 These size parameters can be formed into a database based on the big data of mainstream tents and pre-stored in the memory. f and S b The unit is m 2 , that is, square meters; the total exposed area of the tent is S b It refers to the sum of the areas of all the facades of the tent except the bottom, including the side walls and the top. It is understandable that since only the outer tent is directly irradiated by sunlight in the overlapping area of the outer tent and the inner tent, the area of the overlapping area is only calculated once. It is easy to understand that the irradiated area S of the tent under the midday sun f Equal to its total exposed area S b When the sun is shining or setting, the sun is close to the horizon and the sunlight cannot completely cover the total exposed area S of the tent. b , then you can set the irradiated area S of the tent f The exposed area on the side facing the sun, for example, can be its total exposed area S b That is, in this embodiment, optionally, the irradiated area S f There are multiple gradient values corresponding to multiple time periods, for example, multiple time periods include from sunrise to 8 am, from 8 am to 4 pm, and from 4 pm to sunset. In the first time period and the third time period, the irradiated area S of the tent is f Equal to its total exposed area S b In the second time period, the irradiated area of the tent is S f Equal to its total exposed area S b Of course, in other embodiments, the irradiated area S f You can also keep the factory default value constant, for example, the factory default setting is the irradiated area S of the tent. f = Total exposed area of the tent S b .
[0091] Further optionally, the heat conduction Q 3 The calculation formula is: 3 =K*S f *(T W1 -T)+K*(S b -S f )*(T W2 -T)+K*Sd *(T W3 -T); where K is the heat transfer coefficient of the enclosed space, in W / (m 2 ·K), that is, W / (square meter·Kelvin); S f is the irradiated area of the enclosed space, S b is the total exposed area of the enclosed space, S d is the bottom area of the enclosed space; T W1 is the external surface temperature of the solar-radiated facade of the enclosed space, T W2 is the external surface temperature of the facade of the enclosed space that is not exposed to solar radiation, T W3 is the outer surface temperature of the bottom surface of the enclosed space, T W1 , T W2 , T W3 The unit of is ℃, that is, Celsius. That is, in this embodiment, the heat conduction Q 3 Contains the unknown field temperature T. It can be understood that T W1 , T W2 , T W3 In fact, it represents the outer surface temperature of different areas on the outer side of the closed place. The outer side is divided into at least three areas based on whether it is irradiated by the sun and whether it touches the ground, including the facade area irradiated by the sun, the facade area not irradiated by the sun, and the bottom area. The outer surface temperatures of these three areas may be different. However, in order to simplify the calculation steps and calculation time of the processor, this embodiment can optionally set T W1 =T W2 =T W3 , then the heat conduction of the place is Q 3 =K*S z *(T W1 -T), S z It is the total surface area of the enclosed place, which refers to the sum of all surface areas of the tent including the facade and the bottom, that is, the total surface area S z It is equal to the total exposed area plus the bottom area. For example, the total surface area of a two-person hexagonal tent is set to 14m 2 These size parameters can be summarized based on the big data of mainstream tents, and then form a standard model database and pre-stored in the memory. d and S z The unit is m 2 , that is, square meters. Of course, in other embodiments, it can also be T W1 , T W2 and T W3 The values of at least two of the three are configured to be different, for example, T W1 =(T W2 +5)=(T W3+10). Further optionally, the value range of the heat transfer coefficient K of the tent is 1W / (m 2 ·K)≤K≤10W / (m 2 ·K), for example, K=5W / (m 2 ·K).
[0092] In this embodiment, the outer surface temperature T of the enclosed space can be W1 The calculation formula is: W1 =T h +B / C 3 ; Among them, T h is the ambient temperature, which refers to the outdoor temperature in the environment where the tent is located, in degrees Celsius; B is the solar radiation intensity; C 3 is the heat transfer correction coefficient for closed places. Without loss of generality, vehicles are usually equipped with an air inlet temperature sensor, which is used to detect the temperature outside the vehicle. The ambient temperature of the tent and the vehicle is basically the same, so the ambient temperature of the tent can directly refer to the data measured by the air inlet temperature sensor on the vehicle. Of course, in other embodiments, the vehicle air conditioning system can also use the Internet or the Internet of Things to indirectly obtain the ambient temperature of the tent from other information channels, such as obtaining weather forecast information of the city / region to which the location belongs based on the vehicle's positioning information, where the weather forecast information includes the ambient temperature (i.e., the outdoor temperature), and use the solar radiation intensity information as the ambient temperature T of the tent. h . The tent's sunshade correction factor C 3 The value range is 35≤C 3 ≤65, for example, C 3 =50. Of course, in other embodiments, it can also be T W1 Configured to be higher than a fixed value of the ambient temperature, such as T W1 =(T h +10).
[0093] Further optionally, the fresh air load Q 4 The calculation formula is: 4 =(T h -T)*C 4 ; Among them, T h is the ambient temperature, C 4 is the fresh air correction factor for the closed space. That is, the fresh air load Q in this embodiment is 4 It is linearly related to the temperature difference between the inside and outside of the tent, and the fresh air load Q 4Contains the unknown field temperature T. It can be understood that the entrance and exit and ventilation windows of the tent can usually be selectively opened or closed by the user to enhance the exchange rate of air inside and outside the tent. Of course, some tent products have at least one ventilation window that cannot be closed; the opening and closing of these areas will significantly affect the amount of outside air flowing into the enclosed place. Due to the complexity of the use of tents, in this embodiment, C 4 The value range is 0<C 4 ≤50, define the ratio between the total air exchange cross-sectional area of the tent and the total exposed area of the tent as x, and set it to when 0%<x≤5%, C 4 =10; when 5%<x≤10%, C 4 =15; when 10%<x≤15%, C 4 =20; when 15%<x≤20%, C 4 =25, and so on, until C 4 =50; the user can estimate the x value and input it into the vehicle air conditioning system through the human-computer interaction interface, so that the vehicle air conditioning system can determine the matching C according to the actual x value. 4 It is understandable that when users want to keep the heating or cooling effect in the tent at a relatively stable state, they usually close the entrances and windows that can be closed on the tent tightly. However, considering that there will inevitably be some holes or gaps on the tent even after closing it tightly, the value C is taken. 4 = 10 to indicate that all entrances and windows of the tent are closed. Therefore, the fresh air correction factor C in the closed place can be selected. 4 Constant value Factory default value, C 4 =10, which can simplify the processor's calculation steps and calculation time.
[0094] Of course, in other embodiments, it can also be determined according to the type and size parameters of the tent, wherein the type and size parameters include the number and area of the ventilation windows, etc. The user inputs the ratio x on the vehicle-mounted central control screen according to the actual situation, and the processor can select C according to different ratios x. 4 or according to the tent type, the number of ventilation windows and / or the ventilation window area input by the user, the processor calculates the ratio x accordingly, and then selects C according to different ratios x 4 value.
[0095] Further optionally, the heat dissipation of the living body Q 5 The calculation formula is: 5 =R 5 *N; where N is the number of people in the closed place, R 5It is the heat dissipation of a single user, in W, i.e., watts. It can be understood that the living beings that move in the tent are usually only the user, and only in very rare cases will other living beings such as pets enter the tent, so the heat dissipation of the living being Q in this embodiment is 5 Only the heat dissipation of the user is considered. Optionally, R 5 The value range is 80W≤R 5 ≤120W, for example, R 5 =100W.
[0096] Without loss of generality, the specifications of mainstream tents are usually single tents, double tents and triple tents, and when outdoor activities are carried out as a family unit, the number of members in each family is usually 2 to 4. Therefore, the value of N can be based on the above-mentioned big data statistics, and the value is set by default when the car air-conditioning system leaves the factory, such as N = 2. Of course, it can also be a value entered by the user according to the actual situation, such as entering N = 1 or N = 3 through the car's central control screen or the mobile phone application. Or the user enters the size specification or type of the tent, such as entering a double hexagonal tent, and the car air-conditioning system judges N = 2 accordingly.
[0097] Of course, the value of N can also be automatically confirmed by the vehicle air conditioning system according to the measured data. For example, in one embodiment, the vehicle air conditioning system also includes a personnel detector arranged in the passenger compartment, which is electrically connected to the processor and can detect the personnel in the passenger compartment. Specifically, the personnel detector can be a camera, an infrared sensor or a pressure sensor, etc. For example, the image in the passenger compartment can be collected by a camera arranged in the passenger compartment, and the image can be analyzed to determine the number of people in the passenger compartment and the location of the people; or the number of people in the passenger compartment and the location of the people can be identified by an infrared sensor; or a pressure sensor is arranged on the seat, and when someone is sitting on the seat, the pressure sensor will be triggered to confirm the number of people in the passenger compartment and the location of the people. In this way, when the user drives to the outdoor venue, the vehicle air conditioning system can automatically obtain the accurate number of people in the car through the personnel detector, for example, it is measured that there are 4 people in the car; then when the user arrives at the outdoor venue and enters the tent and chooses to turn on the outdoor air supply mode, the vehicle air conditioning system will substitute N=4 into the heat dissipation Q of the living body. 5 , thereby improving the intelligence and ease of use of the vehicle air-conditioning system.
[0098] Of course, in other embodiments, it can also be the heat dissipation of the living body Q 5 =R 5 *N+(R 5 ')*(N'); where N is the number of people in the closed place, R 5 is the heat dissipation of a single user, N' is the number of animals in the enclosure, R 5' is the heat dissipation of a single animal, including cats, dogs and pets.
[0099] It can be understood that the heat load Q of the enclosed space in the technical solution of the present invention is a The calculation of Q can also include other heat loads, such as the heat dissipation of electrical equipment in the tent, that is, a =Q 2 +Q 3 +Q 4 +Q 5 +Q 6 ; Among them, Q 6 It is the heat dissipation of the electrical equipment in the tent, which is expressed as the heat dissipated by the electrical equipment when the user uses electrical equipment such as lighting and electric blankets in the tent. In other embodiments, a variety of standard models are summarized based on the big data (including experimental data) of different enclosed places and pre-stored in the memory to form a database for retrieval. For example, after the user selects the enclosed place as a two-person hexagonal tent and the number of ventilation windows of the tent is 2 in the human-computer interaction interface, the processor directly retrieves the heat load Q containing the unknown number T corresponding to the two-person hexagonal tent in the database a Expression, without the need to calculate the heat load Q indirectly step by step a .
[0100] Step S13: Calculate the temperature T in the field according to the heat balance formula; when the closed place tends to thermal equilibrium, there is a heat balance formula Q a =C 1 Q b , C 1 is the proportion coefficient.
[0101] Specifically, when the tent is in thermal equilibrium, it means that the portion of the cooling or heating performance of the vehicle air conditioner used for the tent is exactly equal to the heat load of the tent. At this time, the temperature inside the tent is stable at a certain value. Of course, since the heat load of the tent is dynamically changing, the thermal balance is a dynamic equilibrium state. 1 Indicates the proportion of the vehicle air conditioner performance actually used for temperature regulation in the tent, C 1 The value range is 0<C 1 ≤1, for example, when the air outlet where the ventilation pipe is located is opened and the other air outlets are closed, so that the cooling or heating airflow generated by the car air conditioner is introduced into the tent, so that the entire cooling performance or heating performance of the car air conditioner is used to adjust the temperature in the tent, at this time, the proportion coefficient C 1 =1.
[0102] This embodiment uses a theoretical calculation method, that is, uses the heat balance formula to calculate the indoor temperature T. It only needs to use the existing parts on the vehicle (including sunlight sensors, air intake temperature sensors, etc.), and there is no need to set up an additional temperature sensor with wireless communication function in the tent. In this way, the structure of the vehicle air-conditioning system can be simplified and the parts configuration cost in the outdoor air supply mode can be reduced.
[0103] In the third embodiment of the vehicle air conditioning system control method of the present invention, based on the above second embodiment of the vehicle air conditioning system control method, before step S13, the vehicle air conditioning system control method further includes steps S14 and S15.
[0104] Step S14: Obtain the external air flow rate of the vehicle air conditioner.
[0105] Specifically, the external air supply flow refers to the flow of the cooling or heating gas generated by the vehicle air conditioner that is introduced into the tent in the external air supply mode. The ratio of the external air supply flow to the total flow of the vehicle air conditioner can be used to express the proportion coefficient C. 1 . In the embodiment where the air outlet includes an external air outlet, optionally, an air flow meter is provided on the air flow branch where the external air outlet is located (such as the external air outlet or the external air duct) to detect the flow data on the air flow branch, and the flow on the air flow branch is used as the air supply flow outside the vehicle. In the embodiment where the air outlet only includes the internal air outlet, optionally, an air flow meter is provided on each air flow branch where the internal air outlet is located (such as the internal air outlet, the internal air duct or the blower) to detect the flow data on each air flow branch, and then the flow of the air flow branch connected to the ventilation pipe is used as the air supply flow outside the vehicle. Of course, the air supply flow outside the vehicle can also be obtained by other means. For example, in the embodiment where the external air outlet is provided with a rotating electric damper, the opening angle of the electric damper can also be detected, and the air supply flow outside the vehicle can be calculated based on the opening angle.
[0106] Step S15: Calculate the ratio of the air flow outside the vehicle to the total flow of the vehicle air conditioner and use it as the proportion coefficient C 1 .
[0107] In this embodiment, the total flow rate of the vehicle air conditioner refers to the mass flow rate q v As can be seen from the above, this parameter is related to the blower speed, circulation mode and other working conditions of the vehicle air conditioner, and has been clearly defined as a matrix database during calibration. Therefore, this parameter will not be affected by whether the passenger compartment is allocated cooling or heating airflow. Therefore, after obtaining the external air supply flow by direct or indirect means, the ratio of it to the total flow of the vehicle air conditioner can be calculated and used as the proportion coefficient C 1 .
[0108] It can be understood that in an ideal state, only the air outlet where the ventilation pipe is located is open and the other air outlets are closed, so that the cooling or heating airflow generated by the car air conditioner is introduced into the tent, so that the entire cooling performance or heating performance of the car air conditioner is used to adjust the temperature in the tent. At this time, the proportion coefficient C 1 =1. However, it is understandable that in the embodiment where the air outlet needs to be manually closed by the user, the user may forget to close the remaining air outlets. For example, some of the internal air outlets in the passenger compartment are still open, so that part of the cooling airflow or heating airflow flows into the passenger compartment. In this case, the proportion coefficient is C 1 <1. In addition, in the embodiment where each air outlet is equipped with an electric damper, even if the remaining air outlets are automatically closed after the vehicle enters the outdoor air supply mode, and only the air outlet where the ventilation duct is located is kept open, other situations may occur that cause part of the cooling airflow or heating airflow to still flow into the passenger compartment. For example, if different users stay in the passenger compartment and the tent respectively, and both the passenger compartment and the tent have cooling or heating needs, the cooling or heating airflow of the vehicle air conditioning system will be distributed to the two spaces in a certain proportion to meet the usage needs of both spaces at the same time.
[0109] In this embodiment, the actual air flow rate outside the vehicle is measured and calculated with the total flow rate of the vehicle air conditioner to obtain a more accurate proportion coefficient C. 1 In this way, the evaluation result of the temperature T in the field can be more accurate. Of course, in other embodiments, C 1 It can also be set to a constant factory default value, such as C 1 =1, which means that by default, only the air outlet where the ventilation duct is located is opened in each external air supply mode.
[0110] In order to make it easier to understand the technical solution of the present invention, an example will be given below to explain it. Specifically, the tent is set to be a two-person hexagonal tent. At noon in the hot summer, the tent and the vehicle are both exposed to the sun. Both users are active in the tent. The vehicle air conditioning system is in the outdoor air supply mode and the user's set temperature is 24°C. The vehicle air conditioner is cooled according to working condition 1 and the mass flow rate q v =300kg / h; except for the ventilation pipe in use and its external air outlet (or internal air outlet) which are in the open state, the other external air outlets and internal air outlets are all in the closed state, so that the cooling performance of the car air conditioner is basically used for the tent, that is, the proportion coefficient C 1 = 1. The vehicle is equipped with an inlet temperature sensor, an outlet temperature sensor and a sunlight sensor, and measures the ambient temperature and the inlet temperature T respectively. 1 = Ambient temperature T h =35℃, air outlet temperature T 2 =10℃, solar radiation intensity B = 800W / m 2If the inlet humidity and outlet humidity are both set to 50%, the enthalpy value h of the air inlet of the vehicle air conditioner can be obtained by looking up the table. i =81kj / kg, enthalpy value of the air outlet of the car air conditioner h i =19.5 kj / kg. Further set the solar penetration coefficient of the tent η = 0.1, the solar radiation absorption coefficient of the tent ρ = 0.5, and the outer surface heat transfer coefficient of the tent a n =15W / (m 2 K), the heat transfer coefficient of the inner surface of the tent a w =25 / (m 2 K), the irradiated area of the tent S f = Total exposed surface S of the tent b =8m 2 , the total surface area of the tent is S z =14m 2 , the tent's sunshade correction factor C 2 =1, the heat transfer coefficient of the tent is K = 5W / (m 2 K), the tent's sunshade correction factor C 3 =50, the fresh air correction factor C of the tent 4 = 10. Further assume that the number of people in the tent is N = 2, and the heat dissipation of a single user is R 5 =100W. Further set T W1 =T W2 =T W3 , then the heat conduction of the place is Q 3 =K*S z *(T W1 -T).
[0111] According to the heat load calculation formula Q a =Q 2 +Q 3 +Q 4 +Q 5 、Car air conditioner performance calculation formula Q b =q v *(h i -h o ), and the heat balance formula Q a =Q b , we get the equation:
[0112] [(η+ρ*a n / a w )*J*C 2 ]+[K*S z *(T W1 -T)]+[(T h -T)*C 4 ]+R 5 *N=qv *(h i -h o );
[0113] That is to say
[0114] [(η+ρ*a n / a w )*(B*S f )*C 2 ]+{K*S z *[(T h +B / C 3 )-T]}+[(T h -T)*C 4 ]+R 5 *N=q v *(h i -h o );
[0115] Substituting the above parameters into the equation yields:
[0116] [2560+(3570-70T)+(350-10T)+200]W=18450kj / h;
[0117] The unit on the left side of the equation is W, and the unit on the right side of the equation is kj / h, so it is necessary to convert the units, and finally get: the field temperature T = 19.4°C.
[0118] The value of 19.4℃ represents the temperature inside the tent when it finally reaches thermal equilibrium under the current conditions of the external environment, tent condition and vehicle air conditioning performance. Comparing the temperature inside the tent with the user's set temperature, it can be seen that if the temperature inside the tent is 19.4℃ and is lower than the user's set temperature of 24℃, it is determined that the air conditioning cooling output is excessive. The temperature inside the tent can be increased and brought as close to the user's set temperature of 24℃ as possible by reducing the air volume of the vehicle air conditioner or increasing the air temperature of the vehicle air conditioner (for example, reducing the power / speed of the compressor) at thermal equilibrium, so that the temperature inside the tent can meet the user's usage needs as much as possible and improve comfort.
[0119] It can be understood that if the enclosed place is not a tent, but a cabin or a bamboo house, etc., then its structural characteristic parameters including solar penetration coefficient, solar radiation absorption coefficient, irradiated area, etc. (i.e., parameters affected by its own structure and material characteristics) may be different from those of a tent, and affect the calculation results of the thermal balance formula. Therefore, in this embodiment, optionally, these structural characteristic parameters can be summarized based on the big data of common tents, outdoor cabins, bamboo houses, etc., and then form a standard model database and pre-store it in the memory, and then it can be selected and called according to the user's input information. For example, when the user enters the enclosed place as a cabin on the human-computer interaction interface, the processor retrieves the structural characteristic parameters corresponding to the cabin standard model and substitutes them into the thermal balance formula to obtain the unknown field temperature T. In this way, the application flexibility and control accuracy of the vehicle air-conditioning system control method can be improved.
[0120] In the fourth embodiment of the vehicle air conditioning system control method of the present invention, based on the above-mentioned first embodiment of the vehicle air conditioning system control method, the vehicle air conditioning system control method further includes step S50 and step S60.
[0121] Step S50: receiving a sleep mode signal.
[0122] In this embodiment, the source of the sleep mode signal has various forms, for example, the user can directly select the sleep mode option by operating the human-computer interaction interface (such as an application on a mobile phone), thereby generating a sleep mode signal and causing the vehicle air conditioning system to enter the sleep mode immediately; or it can be to set the scheduled sleep time so that the vehicle air conditioning system enters the sleep mode regularly. In some embodiments, the vehicle air conditioning system can also wirelessly communicate with the smart watch worn by the user. When the smart watch determines that the user has entered sleep through monitoring information such as heart rate, the smart watch generates a sleep mode signal and sends it to the vehicle air conditioning system. In other embodiments, the sleep mode signal can also be generated according to the power consumption of the vehicle. It can be understood that it is becoming more and more popular to use the power battery of the vehicle as a technology for outdoor power consumption, which enables electrical equipment such as chandeliers in the tent to be electrically connected to the power battery. In this way, by monitoring the power consumption of the power battery, it can be used to determine whether the user has entered sleep. For example, after the chandelier is turned off, the power consumption rate of the power battery will decrease, and it is determined that the user has entered sleep and a sleep mode signal is generated. In some other embodiments, the vehicle positioning information is used to obtain the weather forecast information of the city / region to which the location belongs, wherein the weather forecast information includes the sunrise time and the sunset time, and the time of entering the night is judged accordingly, and a sleep mode signal is generated after entering the night, or a sleep mode signal is generated 4 hours after entering the night. Of course, in other embodiments, multiple conditions can also be combined for judgment, for example, when the time enters the night and the power consumption rate of the power battery decreases, a sleep mode signal is generated.
[0123] Step S60: Control the vehicle air conditioning system to enter a sleep mode, wherein the sleep mode includes increasing the air outlet temperature of the vehicle air conditioning system and / or reducing the air outlet volume of the vehicle air conditioning system.
[0124] In this embodiment, the vehicle air conditioning system will keep the temperature in the vehicle as close to the user's set temperature as possible in normal mode to meet the user's activity needs. When the user falls asleep, the temperature in the vehicle can be appropriately increased to facilitate the user's sleep and health, especially when the temperature difference between day and night is large, thereby improving the user experience. Specifically, the temperature in the vehicle after thermal equilibrium can be set 1°C to 3°C higher than the set temperature.
[0125] The present invention further provides a storage medium storing a vehicle air conditioning system control program. When the air conditioning system control program is executed by a processor, the steps of the aforementioned vehicle air conditioning system control method can be implemented.
