Description

Air conditioning performance testing method, device and system Technical Field

[0001] The present application relates to the field of mechanical and electronic technology, and in particular to an air conditioning performance testing method, device and system. Background Art

[0002] Automotive air conditioners are crucial components for ensuring passenger comfort, providing functions such as cooling, heating, defrosting, defogging, dehumidification, and ventilation. Therefore, to ensure passenger comfort, automotive air conditioner performance testing is essential. Generally speaking, automotive air conditioner performance testing can be categorized into component-level and vehicle-level testing. Vehicle-level testing typically encompasses vehicle-level heating and cooling performance testing, vehicle-level defrosting and defogging performance testing, and vehicle-level passenger thermal comfort testing, providing a comprehensive assessment of automotive air conditioner performance. However, vehicle-level testing, conducted at the end of the vehicle development cycle, suffers from long testing cycles, high verification costs, and limited test conditions. Therefore, to verify automotive air conditioner performance as early as possible and reduce testing costs, vehicle-level testing is essential. However, in the early stages of vehicle development, a complete vehicle is not available, making it difficult to conduct vehicle-level testing of the passenger compartment.

[0003] To address the above issues, there are currently two main solutions.

[0004] The first solution is to use an enthalpy difference laboratory instead of the actual passenger compartment. The enthalpy difference laboratory consists of two laboratories, namely the indoor laboratory (i.e. enthalpy difference chamber 1) and the outdoor laboratory (i.e. enthalpy difference chamber 2). By controlling the air conditioner, heater, humidifier, cooler and air duct and other components located in the enthalpy difference chamber 1, the temperature and humidity of the enthalpy difference chamber 1 are controlled to simulate the internal environment of the passenger compartment. By controlling the air conditioner, heater, humidifier, cooler and air duct and other components located in the enthalpy difference chamber 2, the temperature and humidity of the enthalpy difference chamber 2 are controlled to simulate the external environment of the passenger compartment. This solution is widely used in air conditioning component testing, and is mainly used to measure the cooling capacity, heating capacity and energy efficiency ratio (Coefficient Of Performance, COP) of the air conditioner under steady-state conditions. However, this solution has the disadvantages of large size and high cost. At the same time, since the strong interaction between the air-conditioning thermal management system and other thermal management systems (such as the battery thermal management system, the motor thermal management system, etc.) in the context of the highly integrated thermal management system of today's vehicles is not taken into consideration, the test conditions of a single air-conditioning component have limitations.

[0005] The second solution is to use a simulated passenger compartment of the same size instead of the actual passenger compartment. This solution simulates the external environment in the same way as the enthalpy difference laboratory. The difference is that a simulated passenger compartment with the same size as the actual vehicle is used instead of the actual passenger compartment. The air conditioning box is placed in the simulated passenger compartment to achieve temperature and humidity control in the passenger compartment. This solution is mainly used for air conditioning system function testing and control strategy testing. However, because this solution does not take into account the strong interaction between the air conditioning thermal management system and other thermal management systems in the context of the highly integrated thermal management system of today's vehicles, the test conditions of a single air conditioning component are limited. At the same time, in the early stages of vehicle development, the manufacturing cost of the simulated passenger compartment is relatively high.

[0006] Summary of the Invention

[0007] The embodiments of the present application provide an air conditioning performance testing method, device, and system to reduce the cost of setting up an air conditioning testing environment.

[0008] In a first aspect, embodiments of the present application provide an air conditioner performance testing method. This method can be performed by an air conditioner performance testing device or a component (such as a chip system or circuit) that supports the air conditioner performance testing device in performing the functions required by the method. Optionally, taking the air conditioner performance testing device performing the air conditioner performance testing method as an example, in this method, the air conditioner performance testing device can first obtain first air outlet parameters of the target object's air conditioner to be tested. The air conditioner performance testing device can then input these first air outlet parameters into a first simulation model to predict first environmental parameters of the target object's interior space. The first simulation model is used to represent the correspondence between the air outlet parameters of the target object's air conditioner to be tested and the environmental parameters of the target object's interior space. The air conditioner performance testing device can then determine the performance of the target object's air conditioner to be tested based on the first environmental parameters. In this way, by using the first simulation model to replace the actual target object's interior space, this method can reduce the manufacturing cost of the target object's interior space, help reduce the testing cost of the target object's air conditioner to be tested, thereby reducing the cost of setting up the air conditioner test environment and improving air conditioner testing efficiency.

[0009] In one possible design, determining the performance of the air conditioner to be tested based on the first environmental parameter includes:

[0010] The first environmental parameter is input into the air conditioning performance evaluation model to determine the performance of the air conditioning to be tested. The air conditioning performance evaluation model is used to represent the corresponding relationship between the environmental parameters of the internal space of the target object and the performance of the air conditioning to be tested.

[0011] In the above design, the air-conditioning performance testing device can timely and accurately evaluate the performance of the air-conditioning to be tested through a pre-set air-conditioning performance evaluation model.

[0012] In one possible design, the air conditioning performance evaluation model includes at least one of the following: a heating performance evaluation model, a cooling performance evaluation model, a occupant thermal comfort evaluation model, or a defrosting and defrosting performance evaluation model;

[0013] Inputting the first environmental parameter into the air conditioner performance evaluation model to determine the performance of the air conditioner to be tested includes:

[0014] When the air conditioning performance evaluation model includes a heating performance evaluation model, the first environmental parameter and the first target environmental parameter of the interior space of the target object are input into the heating performance evaluation model to determine the heating performance of the air conditioner to be tested in a low temperature environment; or

[0015] When the air conditioning performance evaluation model includes a cooling performance evaluation model, the first environmental parameter and the second target environmental parameter of the interior space of the target object are input into the cooling performance evaluation model to determine the cooling performance of the air conditioner to be tested in a high temperature environment; or

[0016] When the air conditioning performance evaluation model includes a personnel thermal comfort evaluation model, the first environmental parameter and the second environmental parameter surrounding the personnel in the interior space of the target object are input into the personnel thermal comfort evaluation model to determine the thermal comfort of the personnel in the interior space of the target object; or

[0017] When the air conditioning performance evaluation model includes a defrosting and defrosting performance evaluation model, the first environmental parameter and the second air outlet parameter of the windshield of the target object are input into the defrosting and defrosting performance evaluation model to determine the defrosting and defrosting performance of the air conditioning to be tested.

[0018] In the above design, different performance evaluation models can be used for different performance characteristics of the air conditioner under test, making the performance evaluation of the air conditioner under test more targeted. Based on this, when evaluating a specific performance characteristic of the air conditioner under test, the pre-set performance evaluation model corresponding to that characteristic can be used, thereby more accurately evaluating the performance of the air conditioner under test.

[0019] In one possible design, after predicting the first environmental parameter of the interior space of the target object, the method further includes:

[0020] The first environmental parameter is sent to the environmental parameter simulation device, and the first environmental parameter is used to assist the environmental parameter simulation device in adjusting the third environmental parameter of the internal circulation inlet of the air conditioner to be tested.

[0021] In the above design, in order to ensure that the environmental parameters (such as air temperature or air humidity) of the internal circulation inlet of the air conditioner to be tested are consistent with the environmental parameters of the internal space of the target object, this can be achieved by introducing an environmental parameter simulation device. This can fit the actual application scenario of the air conditioner to be tested and can make the test results of the air conditioner to be tested more accurate. Based on this, in the process of testing the performance of the air conditioner to be tested, the air conditioner performance testing device can send the first environmental parameter to the environmental parameter simulation device, so that the environmental parameter simulation device adjusts the environmental parameter of the internal circulation inlet of the air conditioner to be tested according to the first environmental parameter, thereby realizing a closed loop of the environmental parameters of the internal circulation of the air conditioner to be tested.

[0022] In one possible design, after predicting the first environmental parameter of the interior space of the target object, the method further includes:

[0023] The first environmental parameter is sent to the thermal management system controller of the target object, and the first environmental parameter is used to assist the thermal management system controller in adjusting the fourth environmental parameter of the battery thermal management system loop, the motor thermal management system loop and the air conditioning thermal management system loop of the target object.

[0024] In the above design, it is taken into account that in the thermal management system, the battery thermal management system loop and the motor thermal management system loop have a certain interactive relationship with the air-conditioning thermal management system loop in certain scenarios, which may cause the air-conditioning thermal management system to be affected to a certain extent. To address this problem, by introducing the battery thermal management system loop and the motor thermal management system loop, the test conditions of the air-conditioning to be tested can be made more comprehensive, so that the test results of the air-conditioning to be tested can be made more accurate. Based on this, in the process of testing the performance of the air-conditioning to be tested, the air-conditioning performance test device can send the first environmental parameter to the thermal management system controller, so that the thermal management system controller adjusts the environmental parameters of the battery thermal management system loop, the motor thermal management system loop and the air-conditioning thermal management system loop (such as the temperature and flow rate of the cooling medium in the loop) according to the first environmental parameter, thereby realizing the control closed loop of the air-conditioning thermal management system.

[0025] In a possible design, the first air outlet parameter includes at least one of the following: air outlet temperature, air outlet humidity, air outlet speed, air outlet volume, or air outlet direction.

[0026] In the above design, by collecting the actual air outlet parameters of the air conditioner to be tested, the first simulation model can more accurately predict the environmental parameters of the interior space of the target object.

[0027] In one possible design, the target object is a cabin-type equipment with manned functions.

[0028] In a possible design, the first environmental parameter includes at least one of the following: air temperature, air humidity, air direction, air speed, or air volume.

The air conditioning performance testing device has the function of implementing the behavior in the method example of the first aspect. The function can be implemented by hardware, or by hardware executing corresponding software. The hardware or software includes one or more modules corresponding to the above functions. In one possible design, the air conditioning performance testing device includes an acquisition module and a processing module. The acquisition module is used to obtain the first air outlet parameters of the air conditioner to be tested of the target object. The processing module is used to input the first air outlet parameters into a first simulation model to predict the first environmental parameters of the internal space of the target object. The first simulation model is used to represent the correspondence between the air outlet parameters of the air conditioner to be tested and the environmental parameters of the internal space of the target object. The processing module is also used to determine the performance of the air conditioner to be tested based on the first environmental parameters. These modules can perform the corresponding functions in any possible design of the first aspect.

[0043] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0044] The following describes possible application scenarios of the present application. It should be noted that these descriptions are for the purpose of facilitating understanding by those skilled in the art and are not intended to limit the scope of protection claimed by the present application.

[0045] Figure 1 illustrates a possible application scenario applicable to embodiments of the present application. As shown in Figure 1 , the application scenario includes an air conditioner performance test device 110, an environmental parameter simulation device 120, a target object thermal management system 130, an air conditioner to be tested 140, a battery device 150, and a motor device 160.

[0046] Among them, a first simulation model can be deployed in the air-conditioning performance test device 110. For example, taking the target object as a vehicle, the first simulation model can be a passenger compartment simulation model. Exemplarily, the air-conditioning performance test device 110 can be a laptop or desktop computer deployed with a first simulation model, or it can also be a cluster computer or a large distributed computer with a hardware resource pool deployed with a first simulation model, or it can also be a host computer deployed with a first simulation model (a computer that can directly issue control instructions), or it can also be a cloud (or it can also be called a cloud, cloud, cloud server or cloud server, etc.) deployed with a first simulation model. Optionally, the environmental parameter simulation device 120 deployed with the first simulation model can also serve as the air-conditioning performance test device 110.

[0047] When a first simulation model is deployed in the air-conditioning performance testing device 110, the air-conditioning performance testing device 110 can simulate the real environmental information of the internal space of the target object through the first simulation model, and predict the environmental parameters of the internal space of the target object (such as air temperature, air humidity or air speed, etc.) in real time based on the parameter information of the air outlet of the air conditioner to be tested 140 (such as air temperature, air humidity or air speed, etc.), so as to realize the temperature and humidity closed loop of the internal circulation of the air conditioner to be tested and the control closed loop of the air-conditioning thermal management system.

[0048] Optionally, the air conditioner performance testing device 110 can be directly connected to the air conditioner under test 140 to obtain parameter information of the air outlet of the air conditioner under test 140. Optionally, the air conditioner performance testing device 110 can also obtain parameter information of the air outlet of the air conditioner under test 140 through other devices (such as a host computer or other devices specifically used to collect parameter information of the air outlet of the air conditioner under test 140). Among them, the other device can be directly connected to the air conditioner under test 140 to collect parameter information of the air outlet of the air conditioner under test 140.

[0049] For example, an air conditioning performance evaluation model may also be deployed in the air conditioning performance testing device 110. When the air conditioning performance evaluation model is deployed in the air conditioning performance testing device 110, the air conditioning performance testing device 110 can determine the performance of the air conditioning 140 to be tested using the air conditioning performance evaluation model.

[0050] Optionally, the air conditioning performance evaluation model can also be deployed on other devices (such as other laptops or other desktop computers, etc.). After obtaining the environmental parameters of the internal space of the target object, the other devices use the air conditioning performance evaluation model to determine the performance of the air conditioner 140 to be tested.

[0051] Exemplarily, the air conditioner to be tested 140 has two air inlets, one for external circulation and the other for internal circulation. When the air conditioner to be tested 140 is in the external circulation stage, the air in the environmental chamber enters the air conditioner to be tested 140. When the air conditioner to be tested 140 is in the internal circulation stage, the air in the internal space of the target object simulated by the environmental parameter simulation device 120 enters the air conditioner to be tested 140.

[0052] Optionally, the environmental parameter simulation device 120 may include a controller, an environmental parameter sensor, a heating device, a cooling device, a humidifier, etc.

[0053] The controller is used to manage and control the corresponding functions of the heating device, cooling device, and humidifier, or it can also be used to obtain predicted environmental parameters (such as predicted air temperature or predicted air humidity) of the internal space of the target object from the air conditioner performance testing device 110. For example, the predicted environmental parameters can also be predicted air heat load or air humidity load. The environmental parameter sensor is used to collect the actual air temperature or actual air humidity at the internal circulation inlet of the air conditioner 140 to be tested.

[0054] For example, the following describes the implementation process of the controller in the environmental parameter simulation device 120 controlling the corresponding functions of the heating device, the cooling device, and the humidifier in the environmental parameter simulation device 120 by taking the environmental parameters as air temperature and air humidity as an example.

[0055] Example 1: When the actual air temperature is lower than the predicted air temperature, the controller may control the heating device to increase the heating power so that the air temperature at the internal circulation inlet of the tested air conditioner 140 can be increased to the predicted air temperature.

[0056] Example 2: When the actual air temperature is greater than the predicted air temperature, the controller may control the refrigeration device to increase the refrigeration power so that the air temperature at the internal circulation inlet of the tested air conditioner 140 can be reduced to the predicted air temperature.

[0057] Example 3: When the actual air humidity is lower than the predicted air humidity, the controller may control the humidifier to increase the humidification amount so that the air humidity at the internal circulation inlet of the tested air conditioner 140 can be increased to the predicted air humidity.

[0058] Example 4: When the actual air humidity is greater than the predicted air humidity, the controller can control the refrigeration device to increase the refrigeration power for dehumidification, so that the air humidity at the internal circulation inlet of the air conditioner 140 to be tested can be reduced to the predicted air humidity. At the same time, the controller can control the heating device to increase the heating power so that the air temperature at the internal circulation inlet of the air conditioner 140 to be tested can be maintained at the predicted air temperature.

[0059] In addition, optionally, in one example, the environmental parameter simulation device 120 may be disposed in the environmental chamber shown in Fig. 1. In another example, the environmental parameter simulation device 120 may also be independently disposed outside the environmental chamber shown in Fig. 1 .

[0060] Thermal management system 130 is used to manage the heat generated by multiple devices of the target object during operation. For example, based on the abstract division of the functions of the management objects of thermal management system 130, thermal management system 130 can also be divided into battery thermal management system, motor thermal management system, and air conditioning thermal management system.

[0061] Optionally, the thermal management system 130 can provide a suitable environment (such as a warm environment in winter and a cool environment in summer) for the interior space of the target object by adjusting the temperature and / or flow of the cooling medium in the battery thermal management system circuit, the motor thermal management system circuit, and the air conditioning thermal management system circuit. The thermal management system 130 may include a thermal management system controller and a thermal management system control component. Exemplarily, the thermal management system control component may include but is not limited to: a water pump, a fan, a three-way valve, a solenoid valve, an expansion valve, a compressor, a blower, a positive temperature coefficient (PTC) heater, etc. Exemplarily, the cooling medium may include but is not limited to: ethylene glycol coolant or glycerin coolant, etc.

[0062] For example, during implementation, the battery thermal management system can control the temperature of the battery device 150 by controlling the speed of the compressor, the opening of the battery expansion valve, the speed of the water pump, and the power of the PTC heater. The motor thermal management system can control the temperature of the motor device 160 by controlling the speed of the motor water pump and the speed of the fan. The air conditioning thermal management system can control the temperature of the interior space of the target object by controlling the speed of the compressor, the opening of the expansion valve corresponding to the interior space of the target object (such as the expansion valve of the passenger compartment of a vehicle), the speed of the blower, and the power of the PTC heater. Once the thermal management system architecture is determined, the interaction between the battery thermal management system circuit, the motor thermal management system circuit, and the air conditioning thermal management system circuit depends on the actual operating conditions of the air conditioner 140, the battery device 150, and the motor device 160 to be tested. The switching method between the circuits is determined by the control strategy of the thermal management system controller, and the switching of the circuits can generally be controlled by controlling valve components.

[0063] Optionally, the air conditioner 140 to be tested, the battery device 150, and the motor device 160 may be connected to the thermal management system 130 via a cooling / heating circuit. For example, the thermal management system controller may adjust the temperature and / or flow rate of the cooling medium in the battery thermal management system circuit, the temperature and / or flow rate of the cooling medium in the motor thermal management system circuit, and the temperature and / or flow rate of the cooling medium in the air conditioner thermal management system circuit, respectively, by controlling the operating states of the corresponding thermal management system control components based on the operating conditions of the battery device 150, the motor device 160, and the air conditioner 140 to be tested. This allows the battery device 150 and the motor device 160 to operate within a suitable temperature range, and allows the air conditioner 140 to provide suitable cooling or heating to the interior space of the target object. Exemplarily, the operating conditions of the battery device 150, the motor device 160 and the air conditioner to be tested 140 may include but are not limited to: the battery device 150 is cooling, the air conditioner to be tested 140 is cooling, the battery device 150 is cooling, the air conditioner to be tested 140 is heating, the battery device 150 is heating, the air conditioner to be tested 140 is heating, the motor device 160 is cooling, the air conditioner to be tested 140 is heating, the motor device 160 is cooling, the air conditioner to be tested 140 is cooling, the motor device 160 is heating, the air conditioner to be tested 140 is heating, etc.

[0064] By way of example, the following describes the interaction process between the air conditioning thermal management system circuit and the battery thermal management system circuit or the motor thermal management system circuit through the following possible operating conditions.

[0065] Operating condition 1: the battery device 150 is cooling, and the air conditioner to be tested 140 is cooling.

[0066] When both the battery device 150 and the air conditioner to be tested 140 need cooling, the thermal management system controller distributes low-temperature cooling media of different flow rates to the battery thermal management system circuit and the air conditioner thermal management system circuit by controlling the valve components on the battery side and the valve components on the interior space side of the target object (such as the passenger compartment side of the vehicle).

[0067] Operating condition 2: The battery device is heating at 150°C, and the air conditioner to be tested is heating at 140°C.

[0068] When both the battery device 150 and the air conditioner to be tested 140 need to generate heat, the thermal management system controller distributes high-temperature cooling medium of different flow rates to the battery thermal management system circuit and the air conditioner thermal management system circuit by controlling the valve components on the battery side and the valve components on the interior space side of the target object (such as the passenger compartment side of the vehicle).

[0069] Operating condition three: the battery device 150 is cooling, and the air conditioner to be tested 140 is heating.

[0070] When the battery device 150 needs to be cooled and the air conditioner 140 to be tested needs to be heated, the thermal management system controller controls the corresponding valve components to pass the high-temperature cooling medium of the battery device 150 to the air conditioner thermal management system loop, so that the air conditioner 140 to be tested can be heated in a timely and effective manner, thereby providing corresponding heat for the internal space of the target object.

[0071] Operating condition four: the motor device 160 is cooling, and the air conditioner to be tested 140 is heating.

[0072] When the motor device 160 needs cooling and the air conditioner 140 to be tested needs heating, the thermal management system controller controls the corresponding valve components to pass the high-temperature cooling medium of the motor device 160 to the air conditioner thermal management system loop, so that the air conditioner 140 to be tested can heat in a timely and effective manner, thereby providing corresponding heat for the internal space of the target object.

[0073] The battery device 150 can be used to supply power to the target object. Optionally, the heat generated by the battery device 150 during operation can also be provided to the interior space of the target object.

[0074] Alternatively, in one example, the battery device 150 may be a physical battery (e.g., a battery pack). The battery pack may be connected to the thermal management system 130 via a cooling / heating circuit. In another example, the battery device 150 may be a battery simulation device (e.g., a battery temperature simulation device). In other words, during the performance testing of the air conditioner 140 under test, the tester (or other relevant personnel) may use a battery temperature simulation device instead of a real battery pack.

[0075] For example, Figure 2a illustrates a schematic structural diagram of a battery temperature simulation device provided in an embodiment of the present application. As shown in Figure 2a, the battery temperature simulation device may include a controller, a temperature sensor, a cooling device, and a heating device. Optionally, the battery temperature simulation device may include a flow sensor. The battery temperature simulation device may be connected to the thermal management system 130 via a cooling / heating circuit.

[0076] It should be noted that the connection relationship between the modules shown in Figure 2a is only an example and does not constitute a limitation of the present application. The functions of each module are described below.

[0077] The controller is used to manage and control the corresponding functions of the heating and cooling devices, and can also be used to obtain the predicted temperature of the cooling medium at the outlet of the battery temperature simulation device, or can also be used to obtain the actual temperature of the cooling medium at the outlet of the battery temperature simulation device. The temperature sensor is used to collect the actual temperature of the cooling medium at the inlet of the battery temperature simulation device in real time, and can also be used to collect the actual temperature of the cooling medium at the outlet of the battery temperature simulation device in real time, or can also be used to collect the temperature of the battery temperature simulation device in real time. The flow sensor is used to collect the actual flow rate of the cooling medium at the outlet of the battery temperature simulation device in real time, and can also be used to collect the actual flow rate of the cooling medium at the inlet of the battery temperature simulation device in real time.

[0078] Optionally, the predicted temperature of the cooling medium at the outlet of the battery temperature simulation device can be determined by a device equipped with a battery thermal model using the battery thermal model. For example, the battery thermal model can be deployed on the air conditioning performance testing device 110 , or on another device (such as the environmental parameter simulation device 120 or the cloud).

[0079] For example, using the deployment of a battery thermal model on the air conditioning performance testing device 110 as an example, the air conditioning performance testing device 110 first obtains the current actual temperature of the cooling medium at the inlet of the battery temperature simulation device and the current temperature of the battery temperature simulation device. For example, the air conditioning performance testing device 110 may request the battery temperature simulation device to obtain the current actual temperature of the cooling medium at the inlet of the battery temperature simulation device and the current temperature of the battery temperature simulation device, or the battery temperature simulation device may transmit the current temperature of the battery temperature simulation device and the current actual temperature of the cooling medium at the inlet of the battery temperature simulation device, as collected by the temperature sensor, to the air conditioning performance testing device 110.

[0080] The air conditioning performance testing device 110 can then input the current actual temperature of the cooling medium at the inlet of the battery temperature simulation device, the current temperature of the battery temperature simulation device, and the cooling medium heat transfer coefficient into the battery thermal model to calculate the current heat dissipation of the battery temperature simulation device. The air conditioning performance testing device 110 can also input the battery pack's state of charge (SOC), charge / discharge current, and the current temperature of the battery temperature simulation device into the battery thermal model to calculate the heat generation of the battery temperature simulation device. After calculating the heat generation of the battery temperature simulation device, the air conditioning performance testing device 110 can calculate the temperature of the battery temperature simulation device at the next moment based on the heat generation of the battery temperature simulation device, the current temperature of the battery temperature simulation device, the battery specific heat capacity, and the battery mass. Optionally, the temperature of the battery temperature simulation device at the next moment can be used by the battery thermal model to calculate the heat dissipation of the battery temperature simulation device at the next moment. The heat dissipation of the battery temperature simulation device at the next moment can then be used by the air conditioning performance testing device 110 to calculate the predicted temperature of the cooling medium at the outlet of the battery temperature simulation device at the next moment. For example, the battery pack's SOC and charge / discharge current can be set based on the experience of those skilled in the art, or based on measurements obtained from multiple experiments.

[0081] The air conditioning performance testing device 110 can then calculate the current predicted temperature of the cooling medium at the outlet of the battery temperature simulation device based on the current heat dissipation of the battery temperature simulation device, the specific heat capacity of the cooling medium, the current actual temperature of the cooling medium at the outlet of the battery temperature simulation device, and the cooling medium quality. Optionally, the cooling medium quality can be calculated by the air conditioning performance testing device 110 based on the current flow rate of the cooling medium at the outlet of the battery temperature simulation device, as detected by a flow sensor.

[0082] For example, the following describes the implementation process of the controller in the battery temperature simulation device controlling the corresponding functions of the heating device and the cooling device in the battery temperature simulation device through the following possible examples:

[0083] Example 1: When the current actual temperature of the outlet cooling medium of the battery temperature simulation device is lower than the current predicted temperature of the outlet cooling medium of the battery temperature simulation device, the controller controls the heating device to increase the heating power so that the temperature of the outlet cooling medium of the battery temperature simulation device can be increased to the current predicted temperature.

[0084] Example 2: When the current actual temperature of the outlet cooling medium of the battery temperature simulation device is greater than the current predicted temperature of the outlet cooling medium of the battery temperature simulation device, the controller controls the refrigeration device to increase the refrigeration power so that the temperature of the outlet cooling medium of the battery temperature simulation device can be reduced to the current predicted temperature.

[0085] The motor device 160 can be used to provide driving force to the target object. Optionally, the motor device 160 can also be used to provide electrical energy to the target object. Optionally, the heat generated by the motor device 160 during operation can also be provided to the interior space of the target object.

[0086] Alternatively, in one example, the motor device 160 can be a physical motor (e.g., a motor). The motor can be connected to the thermal management system 130 via a cooling / heating circuit. In another example, the motor device 160 can be a motor simulation device (e.g., a motor temperature simulation device). In other words, during the performance testing of the air conditioner 140 under test, the tester (or other relevant personnel) can use the motor temperature simulation device instead of a real motor.

[0087] For example, Figure 2b illustrates a schematic structural diagram of a motor temperature simulation device provided in an embodiment of the present application. As shown in Figure 2b, the motor temperature simulation device may include a controller, a temperature sensor, a cooling device, and a heating device. Optionally, the motor temperature simulation device may include a flow sensor. The motor temperature simulation device may be connected to the thermal management system 130 via a cooling / heating circuit.

[0088] It should be noted that the connection relationship between the modules shown in Figure 2b is only an example and does not constitute a limitation of the present application. The functions of each module are described below.

[0089] The controller is used to manage and control the corresponding functions of the heating and cooling devices, and can also be used to obtain the predicted temperature of the cooling medium at the outlet of the motor temperature simulation device, or can also be used to obtain the actual temperature of the cooling medium at the outlet of the motor temperature simulation device. The temperature sensor is used to collect the actual temperature of the cooling medium at the inlet of the motor temperature simulation device in real time, and can also be used to collect the actual temperature of the cooling medium at the outlet of the motor temperature simulation device in real time, or can also be used to collect the temperature of the motor temperature simulation device in real time. The flow sensor is used to collect the actual flow rate of the cooling medium at the outlet of the motor temperature simulation device in real time, and can also be used to collect the actual flow rate of the cooling medium at the inlet of the motor temperature simulation device in real time.

[0090] Optionally, the predicted outlet cooling medium temperature of the motor temperature simulation device can be determined by a device equipped with a motor thermal model using the motor thermal model. For example, the motor thermal model can be deployed on the air conditioner performance testing device 110, or on another device (such as the environmental parameter simulation device 120 or the cloud).

[0091] For example, using the example of deploying a motor thermal model on the air conditioning performance test device 110, the air conditioning performance test device 110 first obtains the current actual temperature of the cooling medium at the inlet of the motor temperature simulation device and the current temperature of the motor temperature simulation device. For example, the air conditioning performance test device 110 may request the motor temperature simulation device to obtain the current actual temperature of the cooling medium at the inlet of the motor temperature simulation device and the current temperature of the motor temperature simulation device, or the motor temperature simulation device may transmit the current temperature of the motor temperature simulation device and the current actual temperature of the cooling medium at the inlet of the motor temperature simulation device, as collected by a temperature sensor, to the air conditioning performance test device 110.

[0092] Afterwards, the air conditioning performance testing device 110 can input the current actual temperature of the inlet cooling medium of the motor temperature simulation device, the current temperature of the motor temperature simulation device, and the cooling medium heat transfer coefficient into the motor thermal model to calculate the current heat dissipation of the motor temperature simulation device. Furthermore, the motor speed, torque, and current temperature of the motor temperature simulation device can be input into the motor thermal model to calculate the heat production of the motor temperature simulation device. After calculating the heat production of the motor temperature simulation device, the air conditioning performance testing device 110 can calculate the temperature of the motor temperature simulation device at the next moment based on the heat production of the motor temperature simulation device, the current temperature of the motor temperature simulation device, the motor specific heat capacity, and the motor mass. Optionally, the temperature of the motor temperature simulation device at the next moment can be used by the motor thermal model to calculate the heat dissipation of the motor temperature simulation device at the next moment. The heat dissipation of the motor temperature simulation device at the next moment can be used by the air conditioning performance testing device 110 to calculate the predicted temperature of the outlet cooling medium of the motor temperature simulation device at the next moment. For example, the motor speed and torque can be set based on the experience of those skilled in the art, or can also be set based on measured values ​​obtained from multiple experiments.

[0093] The air conditioning performance testing device 110 can then calculate the current predicted temperature of the cooling medium at the outlet of the motor temperature simulation device based on the current heat dissipation of the motor temperature simulation device, the specific heat capacity of the cooling medium, the current actual temperature of the cooling medium at the outlet of the motor temperature simulation device, and the cooling medium quality. Optionally, the cooling medium quality can be calculated by the air conditioning performance testing device 110 based on the current flow rate of the cooling medium at the outlet of the motor temperature simulation device, as measured by a flow sensor.

[0094] For example, the following describes the implementation process of the controller in the motor temperature simulation device controlling the corresponding functions of the heating device and the cooling device in the motor temperature simulation device through the following possible examples:

[0095] Example 1: When the current actual temperature of the outlet cooling medium of the motor temperature simulation device is lower than the current predicted temperature of the outlet cooling medium of the motor temperature simulation device, the controller controls the heating device to increase the heating power so that the temperature of the outlet cooling medium of the motor temperature simulation device can be increased to the current predicted temperature.

[0096] Example 2: When the current actual temperature of the outlet cooling medium of the motor temperature simulation device is greater than the current predicted temperature of the outlet cooling medium of the motor temperature simulation device, the controller controls the refrigeration device to increase the refrigeration power so that the temperature of the outlet cooling medium of the motor temperature simulation device can be reduced to the current predicted temperature.

[0097] It should be noted that the application scenario shown in Figure 1 above is only an example. This schematic application scenario is intended to more clearly illustrate the technical solution of the embodiment of the present application and does not limit the application scenario of the vehicle positioning method provided by the present application. Moreover, the form and number of each structure in the application scenario shown in Figure 1 are only used for example and do not constitute a limitation on the present application. In addition, the connection relationship between the various structures shown in Figure 1 is only an example and does not constitute a limitation on the present application. In addition, the name of each structure in the application scenario shown in Figure 1 is only an example. The name of each structure in the specific implementation may also be other names, and the present application does not make specific limitations on this.

[0098] As described in the background, existing solutions for testing air conditioner performance require the construction of a large physical object (such as an enthalpy difference laboratory) or the manufacture of a corresponding physical object (such as a simulated passenger compartment), resulting in a relatively high cost for setting up the air conditioner test environment. In view of this, the present application provides an air conditioner performance testing method to reduce the cost of setting up the air conditioner test environment.

[0099] The following is a detailed introduction to the specific implementation of the air conditioning performance testing method in the embodiment of the present application based on the application scenario shown in Figure 1.

[0100] Figure 3 exemplarily shows a flow chart of an air conditioning performance test method provided in an embodiment of the present application. The method is applicable to the application scenario illustrated in Figure 1. The method flow can be executed by an air conditioning performance test device or a component (such as a chip system or circuit, etc.) that can support the air conditioning performance test device to implement the functions required by the method. Optionally, the air conditioning performance test device can be an air conditioning performance test device 110 as illustrated in Figure 1. In order to facilitate the introduction of the technical solution provided in an embodiment of the present application, the following is an example of an air conditioning performance test method performed by an air conditioning performance test device. As shown in Figure 3, the method includes:

[0101] Step 301: The air conditioner performance testing device obtains first air outlet parameters of the target air conditioner to be tested.

[0102] Alternatively, the target object may be a cabin-type device capable of carrying people. For example, the target object may include, but is not limited to, cabin-type devices on land (such as cars, buses, trucks, trains, subways, trams, light rail trains, or high-speed trains), cabin-type devices on water (such as ships), or cabin-type devices in the air (such as airplanes). Alternatively, the target object may be an indoor location capable of accommodating people (such as a data processing facility housing multiple servers or a location used for office work).

[0103] Optionally, the first air outlet parameter may include but is not limited to at least one of the following: air outlet temperature, air outlet humidity, air outlet speed, air outlet volume or air outlet direction, etc.

[0104] For example, taking the target object as a vehicle (such as a car or a bus, etc.), when the air-conditioning performance testing device is directly connected to the air-conditioning to be tested of the vehicle, the air-conditioning performance testing device can collect the first air outlet parameters of the air-conditioning to be tested of the vehicle in real time. When the air-conditioning performance testing device is not directly connected to the air-conditioning to be tested of the vehicle, the air-conditioning performance testing device can obtain the first air outlet parameters of the air-conditioning to be tested of the vehicle through other devices directly connected to the air-conditioning to be tested of the vehicle (such as a host computer or other devices for collecting air outlet parameters). Optionally, other devices can collect the first air outlet parameters of the air-conditioning to be tested of the vehicle in real time, and can send the first air outlet parameters of the air-conditioning to be tested of the vehicle collected in real time to the air-conditioning performance testing device.

[0105] Step 302: The air conditioning performance testing device inputs the first air outlet parameters into the first simulation model to predict the first environmental parameters of the interior space of the target object.

[0106] Optionally, the first simulation model can be used to represent the correspondence between the air outlet parameters of the air conditioner to be tested and the environmental parameters of the interior space of the target object. In this embodiment of the present application, the first simulation model can be used to replace the actual interior space of the target object, that is, the first simulation model can be used to simulate the real environmental information (such as the real heat load) of the interior space of the target object.

[0107] For example, the first simulation model may include, but is not limited to, a zero-dimensional simulation model, a one-dimensional simulation model, a two-dimensional simulation model, a three-dimensional simulation model, or other models capable of predicting first environmental parameters of the interior space of the target object in real time. Optionally, when the target object comprises cabin-type equipment capable of carrying people, the first simulation model may also be referred to as a passenger compartment simulation model, which may be used in place of a real passenger compartment.

[0108] For example, taking a vehicle as the target object, after obtaining the first air outlet parameters of the vehicle's air conditioner under test, the air conditioning performance testing device can input these first air outlet parameters into the passenger compartment simulation model to predict the first environmental parameters of the vehicle's passenger compartment. For example, the first environmental parameters may include, but are not limited to, at least one of the following: air temperature, air humidity, air speed (or air volume), air direction, temperature field, humidity field, or flow field.

[0109] In one example, after predicting a first environmental parameter of the interior space of a target object, the air conditioner performance testing device may send the first environmental parameter to the environmental parameter simulation device. After receiving the first environmental parameter, the environmental parameter simulation device adjusts a third environmental parameter at the internal circulation inlet of the air conditioner under test based on the first environmental parameter, so that the environmental parameter at the internal circulation inlet of the air conditioner under test is consistent with the first environmental parameter, thereby achieving a closed loop of the environmental parameters (e.g., air temperature, air humidity, etc.) of the internal circulation of the air conditioner under test.

[0110] Optionally, regarding the adjustment method of the third environmental parameter of the internal circulation inlet of the air conditioner to be tested, please refer to the detailed description of the corresponding functions of the controller in the environmental parameter simulation device to control the heating device, cooling device and humidifier in the above application scenario part, which will not be repeated here.

[0111] In another example, after predicting the first environmental parameter of the internal space of the target object, the air-conditioning performance test device can also send the first environmental parameter to the thermal management system controller of the target object. After receiving the first environmental parameter, the thermal management system controller can adjust the fourth environmental parameter of the battery thermal management system circuit, the motor thermal management system circuit and the air-conditioning thermal management system circuit (such as the temperature and flow rate of the cooling medium in the circuit) according to the first environmental parameter, so that the motor device and the battery device can operate within a suitable temperature range, and at the same time, the air-conditioning to be tested can provide appropriate cooling or heat to the internal space of the target object, thereby realizing the control closed loop of the air-conditioning thermal management system. Moreover, since this scheme takes into account the interactive relationship between the battery thermal management system circuit, the motor thermal management system circuit and the air-conditioning thermal management system circuit, it can make the test conditions of the air-conditioning to be tested more comprehensive, and can solve the problem that the test conditions of the single air-conditioning component of the existing scheme are limited.

[0112] Optionally, regarding the adjustment method of the fourth environmental parameter of the battery thermal management system loop, the motor thermal management system loop and the air-conditioning thermal management system loop, please refer to the above application scenario section for a detailed description of the thermal management system controller adjusting the temperature and / or flow of the cooling medium of the battery thermal management system loop, the motor thermal management system loop and the air-conditioning thermal management system loop by controlling the corresponding thermal management system control components. No further details will be given here.

[0113] In another example, when an air conditioner performance testing device includes an air conditioner performance evaluation model, after predicting a first environmental parameter of the target object's interior space, the air conditioner performance testing device may also input the first environmental parameter into the air conditioner performance evaluation model to determine the performance of the air conditioner under test. For example, the air conditioner performance evaluation model may be used to represent a correspondence between the environmental parameter of the target object's interior space and the performance of the air conditioner under test.

[0114] Optionally, when the air conditioning performance testing device does not have an air conditioning performance evaluation model deployed, after predicting the first environmental parameter of the target object's interior space, the air conditioning performance testing device may also transmit the first environmental parameter to a device that has an air conditioning performance evaluation model deployed. Upon receiving the first environmental parameter, the device that has the air conditioning performance evaluation model deployed may input the first environmental parameter into the air conditioning performance evaluation model to determine the performance of the air conditioner under test.

[0115] For example, the following describes the implementation process of the air-conditioning performance testing device predicting the first environmental parameter of the interior space of the target object through the first simulation model, taking the first simulation model as a zero-dimensional simulation model or a three-dimensional simulation model as an example.

[0116] Example 1: When the first simulation model is a zero-dimensional simulation model, the zero-dimensional simulation model has the characteristic of treating the air within the target object's interior space as a point mass. When the air within the target object's interior space is treated as a point mass, the air velocity or air volume at each location within the target object's interior space is the same, the air temperature at each location is the same, and the air humidity at each location is the same.

[0117] For example, the following describes the implementation process of the air-conditioning performance testing device predicting the first environmental parameter of the interior space of the target object according to the zero-dimensional simulation model through the following two possible implementation methods.

[0118] Method 1: The air conditioning performance testing device can input the first air outlet parameters of the target object's air conditioning to be tested (such as air outlet temperature, air outlet humidity, air outlet speed (or air outlet volume)), etc. into the zero-dimensional simulation model to predict the first environmental parameters of the target object's internal space (such as air temperature, air humidity, air speed (or air volume)).

[0119] Optionally, the air conditioning performance testing device can also input the light received by the target object, the number of people located in the internal space of the target object, and the first air outlet parameters of the air conditioner to be tested of the target object into the zero-dimensional simulation model to predict the first environmental parameters of the internal space of the target object.

[0120] For example, the illumination received by the target object, the number of people located in the interior space of the target object, etc. can be set according to the experience of those skilled in the art, or can also be set according to measurement values ​​obtained from multiple experiments.

[0121] Method 2: The air conditioning performance testing device can input the heat load and humidity load of the internal space of the target object into the zero-dimensional simulation model to predict the first environmental parameters of the internal space of the target object (such as air temperature, air humidity, air speed (or air volume)).

[0122] For example, if the target object is a vehicle, the thermal load of the vehicle's passenger compartment may include the thermal load of the air conditioner to be tested and other thermal loads. The humidity load of the vehicle's passenger compartment may include the humidity load of the air conditioner to be tested and the humidity load caused by the human body.

[0123] For example, other heat loads may include, but are not limited to, heat loads between vehicle doors, roof, windows, floor, seats, instrument panels, and other components and the air inside the vehicle; heat generated by the human body; heat generated by electronic components within the vehicle; light radiation; and heat loads caused by air leakage within the vehicle. For example, other heat loads may be set based on the experience of those skilled in the art or based on measurements obtained through multiple experiments.

[0124] Alternatively, the humidity load of the air conditioner to be tested can be calculated based on the outlet air speed (or outlet air volume) and outlet humidity of the air conditioner to be tested. The humidity load caused by the human body can be set based on the experience of those skilled in the art, or can also be set based on measured values ​​obtained from multiple experiments.

[0125] Optionally, the air conditioning performance testing device can also input the light received by the target object, the number of people located in the interior space of the target object, and the heat load and humidity load of the interior space of the target object into the zero-dimensional simulation model to predict the first environmental parameters of the interior space of the target object.

[0126] Example 2: When the first simulation model is a three-dimensional simulation model, the three-dimensional simulation model has the characteristic of treating the interior space of the target object as a three-dimensional space. When the interior space of the target object is treated as a three-dimensional space, the air velocity or air volume at each location within the target object's interior space is different, the air temperature at each location is different, and the air humidity at each location is different.

[0127] Optionally, the air conditioner performance testing device may input the light received by the target object, the number of people in the target object's interior space, and the first air outlet parameters of the target object's air conditioner under test (such as outlet air temperature, outlet air humidity, outlet air speed (or outlet air volume), and outlet air direction) into a three-dimensional simulation model to predict the first environmental parameters of the target object's interior space (such as the temperature field, humidity field, or flow field). For example, compared to a zero-dimensional simulation model, a three-dimensional simulation model includes an additional input, namely, outlet air direction.

[0128] For example, the air conditioning performance testing device can input the outlet wind speed (or outlet wind volume) and outlet wind direction of the air conditioning to be tested of the target object into a three-dimensional simulation model to predict the flow field of the target object's interior space. The air conditioning performance testing device can input the flow field of the target object's interior space, the heat load of the air conditioning to be tested, and other heat loads into the three-dimensional simulation model to predict the temperature field of the target object's interior space. The air conditioning performance testing device can input the flow field of the target object's interior space, the humidity load of the air conditioning to be tested, and the humidity load caused by the human body into the three-dimensional simulation model to predict the humidity field of the target object's interior space.

[0129] Step 303: The air conditioner performance testing device determines the performance of the air conditioner to be tested according to the first environmental parameter.

[0130] Optionally, when an air conditioning performance evaluation model is deployed in the air conditioning performance testing device, after obtaining the first environmental parameters of the internal space of the target object, the air conditioning performance testing device can input the first environmental parameters into the air conditioning performance evaluation model to determine the performance of the air conditioner to be tested.

[0131] Exemplarily, the air conditioning performance evaluation model may include but is not limited to at least one of the following: a heating performance evaluation model, a cooling performance evaluation model, a personnel thermal comfort evaluation model, or a defrosting and defrosting performance evaluation model.

[0132] Optionally, based on the above content, the following describes the implementation process of the air-conditioning performance testing device determining the performance of the air-conditioning to be tested according to the air-conditioning performance evaluation model through the following possible examples.

[0133] Example 1: When the air conditioner performance evaluation model includes a heating performance evaluation model, the air conditioner performance testing device may input a first environmental parameter and a first target environmental parameter of the interior space of a target object into the heating performance evaluation model to determine the heating performance of the air conditioner under test in a low-temperature environment. For example, the heating performance evaluation index for the air conditioner under test in a low-temperature environment may include, but is not limited to, at least one of the following: the heating rate of the interior space of the target object, or the air temperature of the interior space of the target object after thermal equilibrium.

[0134] For example, taking the first environmental parameter as air temperature and the target object as a vehicle, when it is necessary to test the heating performance of the air conditioner to be tested in a low-temperature environment, the environmental chamber where the air conditioner to be tested is located provides a low-temperature environment (for example, a temperature of -20°C). The air conditioner performance testing device can obtain multiple predicted air temperatures of the vehicle's passenger compartment, and then input the multiple predicted air temperatures and the target temperature of the passenger compartment set by the tester (or other relevant personnel, etc.) (for example, 30°C) into the warming performance evaluation model, so as to accurately determine the heating performance of the air conditioner to be tested in a low-temperature environment.

[0135] Example 2: When the air conditioner performance evaluation model includes a cooling performance evaluation model, the air conditioner performance testing device may input a first environmental parameter and a second target environmental parameter of the target object's interior space into the cooling performance evaluation model to determine the cooling performance of the air conditioner under test in a high-temperature environment. For example, the cooling performance evaluation index for the air conditioner under test in a high-temperature environment may include, but is not limited to, at least one of the following: the cooling rate of the target object's interior space or the air temperature of the target object's interior space after thermal equilibrium.

[0136] For example, continuing with the first environmental parameter being air temperature and the target object being a vehicle, when it is necessary to test the cooling performance of the air conditioner to be tested in a high-temperature environment, the environmental chamber where the air conditioner to be tested is located provides a high-temperature environment (for example, a temperature of 40°C). The air conditioner performance testing device can obtain multiple predicted air temperatures of the vehicle's passenger compartment, and then input the multiple predicted air temperatures and the target temperature of the passenger compartment set by the tester (or other relevant personnel, etc.) (for example, 20°C) into the cooling performance evaluation model, thereby accurately determining the cooling performance of the air conditioner to be tested in a high-temperature environment.

[0137] Example 3: When the air conditioning performance evaluation model includes a human thermal comfort evaluation model, the air conditioning performance testing device may input a first environmental parameter and a second environmental parameter surrounding a human in the interior space of a target object into the human thermal comfort evaluation model to determine the thermal comfort of the human in the interior space of the target object. For example, thermal comfort evaluation indicators for the human in the interior space of the target object may include, but are not limited to, a predicted mean vote (PMV), a predicted percentage of dissatisfied (PPD), thermal sensation or equivalent temperature, and the like.

[0138] For example, assuming the first environmental parameters are air temperature and air velocity, and the target object is a vehicle, when it is necessary to test the thermal comfort of occupants within the interior space of the target object, the air conditioning performance testing device can input multiple predicted air temperatures, multiple predicted air velocities (or predicted air volumes) of the air conditioning unit under test in a low-temperature environment, as well as the air temperature, air velocity (or air volume), or light radiation surrounding the occupants in the vehicle's passenger compartment, into the occupant thermal comfort evaluation model. This can accurately determine the thermal comfort of the occupants within the vehicle's passenger compartment in a low-temperature environment. For example, the air temperature, air velocity (or air volume), or light radiation surrounding the occupants in the vehicle's passenger compartment can be set based on the experience of those skilled in the art, or can be set based on measured values ​​obtained from multiple experiments.

[0139] Optionally, the air conditioning performance testing device can also input multiple predicted air temperatures, multiple predicted air speeds (or predicted air volumes) of the air conditioning to be tested in a high temperature environment, as well as the air temperature, air speed (or air volume) or light radiation around the occupants in the passenger compartment of the vehicle into the personnel thermal comfort evaluation model, so as to accurately determine the thermal comfort of the occupants in the passenger compartment of the vehicle in a high temperature environment.

[0140] Example 4: When the air conditioning performance evaluation model includes a defogger and defroster performance evaluation model, the air conditioning performance testing device can input the first environmental parameter and the second air outlet parameter of the windshield of the target object into the defogger and defroster performance evaluation model to determine the defogger and defroster performance of the air conditioning to be tested.

[0141] For example, assuming the first environmental parameters are air temperature and air direction, and the target object is a vehicle, when testing the defogger and defroster performance of an air conditioner under test, the air conditioner performance testing device can input multiple predicted air temperatures and air directions for the air conditioner under test in a low-temperature environment, as well as the vehicle's front windshield outlet temperature and outlet wind direction, into the defogger and defroster performance evaluation model. This accurately determines the defogger and defroster performance of the air conditioner under test in a low-temperature environment. For example, the vehicle's front windshield outlet temperature and outlet wind direction can be set based on the experience of those skilled in the art, or based on measured values ​​obtained through multiple experiments.

[0142] Optionally, the air conditioning performance testing device can also input multiple predicted air temperatures, multiple predicted air wind directions, and the outlet temperature and outlet wind direction of the vehicle's front windshield of the air conditioning to be tested in a high-temperature environment into the defogger and defrost performance evaluation model, so as to accurately determine the defogger and defrost performance of the air conditioning to be tested in a high-temperature environment.
