Referring to fig. 2, in an embodiment, the control method of the vehicle cooling and heating defrosting system includes the following steps:
step S10, in the process of the vehicle cooling and heating defrosting system running the heat exchange mode, when detecting that the closing condition of the heat exchange mode is met, controlling the vehicle cooling and heating defrosting system to stop running the heat exchange mode;
optionally, the vehicle is provided with a vehicle cooling and warming defrost system for adjusting the temperature in the vehicle and defrosting, defogging, etc. the windows of the vehicle. And after receiving an instruction of starting the vehicle cooling and heating defrosting system, controlling the vehicle cooling and heating defrosting system to operate a heat exchange mode according to the operation parameters so as to enable the vehicle cooling and heating defrosting system to be in a state of operating the heat exchange mode.
Optionally, the heat exchange mode comprises a cooling mode or a heating mode.
Optionally, before controlling the vehicle cooling and warming defrost system to operate the heat exchange mode according to the operation parameters, the operation parameters need to be determined. Specifically, a target temperature set by a user and an air outlet temperature of the vehicle cooling and heating defrosting system can be obtained, and an operation parameter related to the target temperature set by the user and the air outlet temperature can be determined, wherein the related relationship among the target temperature set by the user, the air outlet temperature and the operation parameter can be obtained according to a previous test, for example, during the previous test, a temperature sensor can be arranged in a driving area, and the operation parameter of the vehicle cooling and heating defrosting system within a proper temperature range where the temperature detected by the temperature sensor in the driving area can maintain the target temperature set by the user under different target temperatures and different air outlet temperatures is tested and used as the operation parameter related to the target temperature and the air outlet temperature, namely, the operation parameter with better temperature regulation and control effects of the vehicle cooling and heating system on the driving area under different working conditions is determined through the previous test, and storing the corresponding association relation. Optionally, since there may be a temperature difference between the temperature inside the vehicle and the temperature outside the vehicle, when determining the operation parameter, the external environment temperature of the vehicle may also be introduced, that is, the operation parameter associated with the target temperature set by the user, the air outlet temperature, and the external environment temperature of the vehicle may be acquired.
Optionally, in the process of operating the heat exchange mode of the vehicle cooling and heating defrosting system, whether a closing condition of the heat exchange mode is met is detected, if the closing condition of the heat exchange mode is met, the vehicle cooling and heating defrosting system is controlled to stop operating the heat exchange mode, and if the closing condition of the heat exchange mode is not met, the vehicle cooling and heating defrosting system is controlled to continuously operate the heat exchange mode.
Optionally, the closing condition of the heat exchange mode may include that the duration of the heat exchange mode of the vehicle cooling and heating defrosting system in this operation is longer than the duration of the operation in the operation parameters. Optionally, the closing condition of the heat exchange mode may include that the heat exchange amount of the vehicle cooling and heating defrosting system in the current operation heat exchange mode is greater than a preset heat exchange amount, for example, a product of the operation power of the vehicle cooling and heating defrosting system in the current operation heat exchange mode and the duration of continuous operation may be used as the heat exchange amount, and when the heat exchange amount is greater than the preset heat exchange amount, it is determined that the closing condition of the heat exchange mode is satisfied.
Step S20, when the starting condition of the heat exchange mode is met, updating the operation parameters of the vehicle cooling and heating defrosting system according to the air outlet temperature of the vehicle cooling and heating defrosting system;
in this embodiment, after the vehicle cooling and heating defrosting system stops operating the heat exchange mode, whether the starting condition of the heat exchange mode is met is detected, when the starting condition of the heat exchange mode is met, the operating parameter is updated according to the temperature of the air outlet of the vehicle cooling and heating defrosting system, and when the starting condition of the heat exchange mode is not met, whether the starting condition of the heat exchange mode is met is continuously detected.
Optionally, the starting condition of the heat exchange mode may include at least one of that the duration of the heat exchange mode of the vehicle cooling and heating defrosting system which is stopped at this time is greater than or equal to a preset duration, that the temperature of the driving area of the vehicle is less than or equal to the target temperature set by the user when the heat exchange mode is the heating mode, and that the temperature of the driving area of the vehicle is greater than or equal to the target temperature set by the user when the heat exchange mode is the cooling mode. When the heat exchange mode is the heating mode, if the temperature of the driving area of the vehicle is less than or equal to the target temperature set by the user, it indicates that the temperature of the driving area is relatively low, and therefore, the heat exchange mode needs to be started to heat the driving area. The duration of the heat exchange mode of the vehicle cooling and heating defrosting system which stops running is longer than or equal to the preset duration, and the influence on the stability of the system caused by frequent starting and stopping of the heat exchange mode of the vehicle cooling and heating defrosting system is avoided through the limitation of the duration of the heat exchange mode which stops running.
Optionally, when the operation parameter is updated according to the air outlet temperature of the vehicle cooling and heating defrosting system, the air outlet temperature can be detected at regular time, the air outlet temperature is compared with the target temperature set by the user, and how to update the operation parameter is judged according to the comparison result. For example, when the heat exchange mode is a cooling mode, if the temperature of the air outlet is detected to be higher than the temperature set by the user within the preset time period, the operation parameters can be updated to improve the heat exchange capability and/or the heat exchange time of the vehicle cooling and heating defrosting system, and for example, when the heat exchange mode is a heating mode, if the temperature of the air outlet is detected to be lower than the temperature set by the user within the preset time period, the operation parameters can be updated to improve the heat exchange capability and/or the heat exchange time of the vehicle cooling and heating defrosting system.
Optionally, the operation parameter represents a heat exchange amount of the vehicle cooling and heating defrosting system, for example, the operation parameter may include an operation power of the heat exchange mode and/or a duration of the heat exchange mode, and the heat exchange capability of the vehicle cooling and heating defrosting system is higher when the operation power is higher.
Optionally, in order to avoid that the temperature regulation efficiency of the driving area is low, when the operation parameters are updated, the operation power of the heat exchange mode is preferentially updated, so that the situation that the user waits too long due to the fact that the updated continuous operation time is long is avoided.
And step S30, controlling the vehicle cold and warm defrosting system to operate the heat exchange mode according to the updated operation parameters. .
In this embodiment, after the operation parameter is updated according to the air outlet temperature of the vehicle cooling and heating defrosting system, the vehicle cooling and heating defrosting system is controlled to operate the heat exchange mode according to the updated operation parameter, so that the vehicle cooling and heating defrosting system is in the process of operating the heat exchange mode again, and whether the closing condition of the heat exchange mode is met is detected again. Therefore, the control flow of the vehicle cooling and heating defrosting system in the embodiment is to control the vehicle cooling and heating defrosting system to be executed for multiple times in a circulating mode between the steps of executing the operation heat exchange mode and stopping the operation heat exchange mode, and adjust the operation parameters of the next operation heat exchange mode according to the air outlet temperature when the vehicle cooling and heating defrosting system stops the operation heat exchange mode, so that the temperature control of the driving area in the vehicle according to the air outlet temperature is realized.
In the technical scheme disclosed in the embodiment, the operation of the vehicle cooling and heating defrosting system is controlled by the temperature of the air outlet after the vehicle cooling and heating defrosting system stops heat exchange, and because the position of the air outlet of the vehicle is close to the driving area of the vehicle, the temperature of the air outlet can more accurately reflect the cooling and heating condition of the driving area, so that after the operation parameters are updated by the temperature of the air outlet after the vehicle cooling and heating defrosting system stops heat exchange, if the heat exchange mode is operated again according to the operation parameters, the accuracy of the cooling and heating defrosting system in controlling the temperature of the driving area can be improved.
In another embodiment, as shown in fig. 3, on the basis of the embodiment shown in fig. 2, before step S20, the method further includes:
step S40, determining the temperature of a driving area of the vehicle according to the temperature of an air outlet of the vehicle cold and warm defrosting system;
in this embodiment, since the driving area of the vehicle is not usually provided with a temperature sensor, after the vehicle cooling and heating defrosting system is controlled to stop operating the heat exchange mode, the air outlet temperature of the cooling and heating defrosting temperature of the vehicle can be obtained at regular time, and the driving area temperature of the vehicle can be estimated according to the air outlet temperature of the cooling and heating defrosting system of the vehicle.
Optionally, when the driving area temperature of the vehicle is estimated according to the air outlet temperature, the distance between the position of the air outlet and the driving area may be obtained, and the driving area temperature of the vehicle may be estimated according to the distance and the air outlet temperature.
Optionally, when the driving area temperature of the vehicle is estimated according to the air outlet temperature, at least one of the temperature change rate of the air outlet temperature and the external environment temperature of the vehicle may be acquired, and the driving area temperature of the vehicle may be estimated according to at least one of the temperature change rate and the external environment temperature, and the air outlet temperature.
And step S50, judging whether the starting condition of the heat exchange mode is met according to the driving area temperature and the target temperature set by the user.
In this embodiment, after the estimated driving area temperature is obtained, the estimated driving area temperature is closer to the real temperature of the driving area than the air outlet temperature, so that when the starting condition of the heat exchange mode is judged to be met according to the driving area temperature and the target temperature set by the user, the temperature control of the driving area is more accurate.
Optionally, the start-up conditions of the heat exchange mode include any one of: (1) when the heat exchange mode is the heating mode, the temperature of the driving area is less than or equal to the target temperature set by a user; (2) when the heat exchange mode is the cooling mode, the temperature of the driving area is greater than or equal to the target temperature set by the user. Optionally, in order to avoid frequently turning on the vehicle cold-warm defrosting system, a suitable temperature range may be set for the target temperature set by the user, for example, a difference between the target temperature set by the user and a preset value is taken as a minimum value of the temperature range, and a sum of the target temperature set by the user and the preset value is taken as a maximum value of the temperature range, so that the starting condition of the heat exchange mode includes any one of the following: (3) when the heat exchange mode is the heating mode, the temperature of the driving area is less than or equal to the minimum value of the temperature range; (4) when the heat exchange mode is a cooling mode, the temperature of the driving area is larger than or equal to the maximum value of the temperature range, wherein the preset values corresponding to the cooling mode and the heating mode can be different.
In the technical scheme disclosed in the embodiment, the temperature of the driving area of the vehicle is estimated according to the temperature of the air outlet of the vehicle cooling and heating defrosting system, and whether the starting condition of the heat exchange mode is met or not is judged according to the estimated temperature of the driving area, so that the temperature of the driving area is more accurately regulated by the vehicle cooling and heating defrosting system.
In still another embodiment, as shown in fig. 4, on the basis of any one of the embodiments shown in fig. 2 to 3, the step of updating the operation parameters of the vehicle cooling and warming defrosting system according to the outlet temperature of the vehicle cooling and warming defrosting system in step S20 includes:
step S21, determining the temperature change rate of the air outlet temperature according to the air outlet temperature;
and step S22, updating the operation parameters according to the temperature change rate of the air outlet temperature.
In this embodiment, when the operation parameter is updated according to the temperature of the air outlet, the temperature change rate of the air outlet can be determined by detecting the temperature of the air outlet, and the operation parameter is updated according to the temperature change rate, for example, when the temperature change rate is relatively large, it indicates that the temperature difference between the temperature of the air outlet and the temperature of other areas in the vehicle is relatively large, it is determined that the operation parameter is unreasonable, and the heat exchange amount of the vehicle cooling and heating defrosting system is insufficient, so that the heat exchange capacity and/or the heat exchange duration of the vehicle cooling and heating defrosting system can be adjusted by updating the operation parameter.
Optionally, the operating parameter comprises an operating power of the heat exchange mode and/or a duration of the heat exchange mode.
Optionally, when the temperature change rate of the air outlet temperature is greater than the first preset change rate corresponding to the heat exchange mode, it indicates that the temperature difference between the air outlet temperature and the temperature of other areas in the vehicle is large, so that the operation power and/or the continuous operation duration in the operation parameters can be increased to update the operation parameters.
Optionally, when the temperature change rate of the air outlet temperature is smaller than a second preset change rate corresponding to the heat exchange mode, a situation that the heat exchange amount of the vehicle cooling and heating defrosting system is too large and the overall temperature in the vehicle is too high may exist, so that the operation power and/or the continuous operation duration in the operation parameters may be reduced to update the operation parameters, where the second preset change rate is smaller than or equal to the first preset change rate.
In the technical scheme disclosed in the embodiment, any updated operation parameter is determined according to the temperature change rate of the air outlet temperature so as to adjust the heat exchange capacity and/or the heat exchange duration of the vehicle cold and warm defrosting system during subsequent starting, and the temperature of the driving area is regulated and controlled by adjusting the operation parameter, so that the temperature of the driving area is more suitable.
In another embodiment, as shown in fig. 5, the heat exchange principle of the vehicle cooling and heating defrosting system is explained based on the embodiment shown in any one of fig. 2 to 4.
When the automobile is used, because the temperature outside the automobile is too low, the temperature difference between the inside and the outside of the automobile is too large, air humidity and other factors are added, the frosting and the fogging of the automobile window are easily caused. If frost and fog on the car window can not be eliminated in time, the sight of a driver is easily shielded, and the driving safety is affected. The vehicle cooling and heating defrosting system achieves vehicle window defrosting and demisting through cooling and heating, and cooling and heating functions of the vehicle cooling and heating defrosting system can also achieve cooling and heating of a vehicle driving area.
As shown in fig. 5, the vehicle cooling/heating defrosting system generally includes a PTC (Positive Temperature Coefficient) heater 1, an evaporator 2, an evaporation fan 3, a compressor 4, a condenser 5, a condensation fan 6, a return air Temperature sensor 7, an expansion valve 8, an outlet air Temperature sensor 9, and a refrigerant pipe 10. When heating is needed, the PTC heater and the evaporation fan are turned on, and hot air is blown out from the air outlet. When refrigeration is needed, the PTC heater is closed, the compressor, the evaporation fan and the condensation fan are opened, the compressor drives the refrigeration system to operate, and the air outlet blows out cold air. The vehicle driver can start cooling or heating according to the self requirement.
In this embodiment, because the air outlet temperature can be rapidly increased or decreased in the heating and cooling operation processes of the cooling and heating defrosting system, and the balance is achieved, the air speed at the air outlet can also affect the detection value of the temperature sensor. Therefore, the outlet temperature cannot be used as an input for temperature control during operation of the defrost system. However, in the shutdown state of the cooling and heating defrosting system, the air outlet is arranged near the driving area, and the temperature of the air outlet is strongly related to the temperature of the driving area, so that the accuracy of the cooling and heating defrosting system in controlling the temperature of the driving area can be improved when the cooling and heating defrosting system of the vehicle is controlled to operate by the temperature of the air outlet after the cooling and heating defrosting system of the vehicle stops heat exchange.
In addition, an embodiment of the present invention further provides a control device for a vehicle cooling and heating defrosting system, where the control device for a vehicle cooling and heating defrosting system includes a memory, a controller, and a control program of the vehicle cooling and heating defrosting system stored in the memory and operable on the controller, and when executed by the controller, the control program of the vehicle cooling and heating defrosting system implements the steps of the control method for the vehicle cooling and heating defrosting system according to the above embodiments.
In addition, an embodiment of the present invention also provides a vehicle, including:
the vehicle cooling and heating defrosting system comprises a first integrated module and a second integrated module which are connected through a refrigerant pipeline, wherein the first integrated module comprises a compressor and a condenser, and the second integrated module comprises an electric heater and an evaporator;
the control device of the vehicle cooling and heating defrosting system according to the above embodiment is used for controlling the vehicle cooling and heating defrosting system.
Optionally, the vehicle cooling and heating defrosting system comprises a PTC heater, a compressor, a condenser, an evaporator, an expansion valve, an evaporation fan, a condensation fan, a refrigerant pipeline, a control system and system accessories, wherein the system accessories comprise a gas-liquid separator, a liquid viewing mirror, a filling port, a high-low voltage wire harness and the like.
Optionally, as shown in fig. 6, the first integrated module includes a compressor 4, a condenser 5, a condensing fan 6, a control system 12 and system accessories 13, and the first integrated module is integrated into a whole when leaving the factory, so that when the first integrated module is installed in a vehicle, it is not necessary to install a single component in a split manner, thereby saving the space of the whole vehicle, simplifying the installation process of the cooling and heating defrosting system, improving the installation convenience and the maintenance convenience. Moreover, because each component in the first integrated module is combined by adopting an integrated process, the components such as the compressor 4, the condenser 5 and the like in the first integrated module can be connected in advance, for example, the outlet of the compressor 4 and the inlet of the condenser 5 are welded and fixed by adopting a welding process, so that the number of joints of a vehicle cold and warm defrosting system is reduced, the leakage probability of a refrigerating system is reduced, and the reliability of the system is improved. And the compressor and the control system are integrated in the first integrated module, the power supply and control mode of the compressor is simple, high-voltage accessories such as an external capacitor and the like are not needed, and the system reliability of the first integrated module is improved.
Alternatively, as shown in fig. 7, the second integrated component includes the evaporator 2, the PTC heater 1, the expansion valve 8, and the evaporation fan 3. Similarly, the second integrated component is integrated as a whole when leaving the factory, and like this, when installing first integrated module in the vehicle, need not to the split type installation of single subassembly to save the space of whole car, simplify changes in temperature defrost system installation process, promote simple to operate nature, promote easy maintenance nature.
Optionally, the first integrated module is disposed at a top of a compartment of the vehicle, that is, the first integrated module is an overhead unit of the vehicle, the second integrated module is disposed at a bottom of the compartment of the vehicle, that is, the second integrated module is a bottom unit of the vehicle, and a control panel is disposed in the compartment of the vehicle and connected to the control system, so that a user in the compartment controls the cooling and heating defrosting system of the vehicle through the control panel.
Alternatively, since when the first integrated module is disposed on the top of the vehicle cabin, the oil carried by the compressor exhaust gas can more easily flow downward from the top of the vehicle cabin to the second integrated component on the bottom of the vehicle cabin, resulting in insufficient oil when the compressor operates, as shown in fig. 6, the first integrated module may further include an oil-gas separator 11, the compressor 4 is connected with the condenser 5 through the oil-gas separator 11, and the oil-gas separator 11 is used for recycling the oil carried by the compressor 4 exhaust gas to the compressor 4, so as to ensure that the compressor 4 has enough oil when operating to ensure the lubricating effect of the internal components of the compressor 4.
