[0022] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without making creative efforts based on the embodiments in the present invention belong to the scope of protection of the present invention.

[0023] The following combines Figures 1 - 3 to describe the temperature - varying adjustment method and device of the air - conditioning equipment of the present invention.

[0024] Figure 1 It is a schematic flow diagram of the temperature - varying adjustment method of the air - conditioning equipment provided by the present invention. As Figure 1 shown, this temperature - varying adjustment method of the air - conditioning equipment is applied to the direct heat pump air - conditioning system of a vehicle and includes the following steps: Step 110: Determine the target heat exchanger according to the temperature - varying operating condition type of the direct heat pump air - conditioning system; wherein, the temperature - varying operating condition type includes a heating operating condition or a cooling operating condition, and the target heat exchanger includes an evaporator or an internal condenser.

[0025] In this step, under the heating operating condition, the direct heat pump air - conditioning system absorbs heat from a low - temperature heat source (such as a ground source, a water source or an air source) and transfers it to the indoor space to achieve a heating effect. At this time, the evaporator in the heat pump unit will go through physical change processes such as evaporation and heat absorption, compression and temperature rise, condensation and heat release, etc., and transfer the absorbed heat to the indoor space; the heat pump air - conditioning system can optimize the heat transfer path by changing the flow direction of the circulating working fluid or changing the fluid medium used in the heat exchanger to improve the heating efficiency.

[0026] In this step, under the cooling operating condition, the heat pump air - conditioning system absorbs heat from the indoor space and discharges it to the external environment or a low - temperature heat source to achieve a cooling effect; the internal condenser in the heat pump unit goes through physical change processes such as condensation and heat release, expansion and temperature drop, evaporation and heat absorption, etc., and discharges the heat of the indoor space.

[0027] Step 120: Obtain the dynamic temperature of the thermoelectric cooler (TEC) based on the in-vehicle ambient temperature and the set in-vehicle temperature of the vehicle. Obtain the compensation value of the dynamic TEC temperature based on the temperature of the target heat exchanger and the in-vehicle ambient temperature. Determine the target TEC temperature based on the static TEC temperature, the dynamic TEC temperature, and the compensation value of the dynamic TEC temperature, and adjust the heating or cooling capacity of the direct heat pump air conditioning system according to the target TEC temperature. Among them, the static TEC temperature is related to the environmental conditions where the vehicle is located.

[0028] In this step, the in-vehicle ambient temperature of the vehicle can be collected by a temperature sensor installed in the vehicle interior, and this measured value is the temperature value to be corrected. The set in-vehicle temperature can be set according to user requirements. For example, when the user needs to raise the temperature in the vehicle, the set in-vehicle temperature can be set to a higher temperature value T0, and when the user needs to lower the temperature in the vehicle, the set in-vehicle temperature can be set to a lower temperature value T1.

[0029] In this embodiment, the temperature of the target heat exchanger can be collected by a temperature sensor or a temperature and pressure sensor installed near the heat exchanger.

[0030] In this embodiment, the static TEC (Thermo Electric Cooler) temperature can be calculated through multiple environmental factors and is associated with the current environmental conditions of the vehicle.

[0031] Specifically, the static TEC temperature is obtained through the following steps: Determine the static TEC temperature based on the in-vehicle ambient temperature, the out-vehicle ambient temperature, the sunlight irradiation value, and the environmental humidity. The in-vehicle ambient temperature is determined based on the user's riding comfort, the operating parameters of key in-vehicle devices, and real-time environmental state variables.

[0032] In this embodiment, since the cooling or heating effect of the TEC is usually achieved during the heat exchange process with the external environment, the out-vehicle ambient temperature can be used as the reference temperature, and a correlation coefficient is introduced to reflect the influence of the difference between the in-vehicle temperature and the out-vehicle temperature on the working temperature of the TEC. This coefficient is associated with the specific vehicle model, insulation material, and the specifications of the TEC.

[0033] It should be noted that since the solar irradiance value will directly affect the temperature distribution outside the vehicle and the cooling / heating effect of the TEC, under direct sunlight, the temperature outside the vehicle may increase significantly, thus increasing the working load of the TEC. In this embodiment, the solar irradiance value is measured or estimated and converted into an influence factor on the working temperature of the TEC; this influence factor also needs to be determined according to the specific vehicle model and TEC specifications; in addition, the environmental humidity has a certain impact on the cooling effect of the TEC. In a high-humidity environment, the moisture in the air will absorb a certain amount of heat, thus reducing the cooling efficiency of the TEC; this embodiment introduces a humidity influence factor to reflect the impact of environmental humidity on the working temperature of the TEC, and this influence factor needs to be determined based on experimental data or experience.

[0034] In this embodiment, the static temperature of the TEC is comprehensively analyzed using the base temperature, the influence coefficient of the vehicle interior environment temperature, the influence factor of the solar irradiance value, and the influence factor of the environmental humidity. In this embodiment, different vehicle interior environment temperatures have different impacts on passenger comfort, and the vehicle interior environment temperature is related to the environmental conditions and the operating conditions of key in-vehicle devices (such as motors and compressors). Through comprehensive analysis of the key in-vehicle devices and the actual temperature, and establishing the correlation between the vehicle interior temperature and comfort, the purpose of allowing users to adjust different vehicle interior temperatures according to different comfort requirements is achieved.

[0035] The specific steps are as follows: (1) Determine the power-consuming and heat-generating devices inside the vehicle; label all the power-consuming devices that may affect the vehicle interior temperature, such as motors, compressors (air conditioners), heaters, audio systems, etc.

[0036] (2) Assign a unique identifier (ID) to each device for easy tracking and management in subsequent diagrams.

[0037] (3) Draw a MAP diagram, create a two-dimensional or three-dimensional MAP diagram, with the device ID as the horizontal axis (or X-axis), and time or other relevant variables as the vertical axis (or Y-axis / Z-axis), and add grid lines in the MAP diagram to more clearly display the data distribution. Each key node in the MAP diagram corresponds to a vehicle device, and different key nodes include the relevant configuration parameters of different devices.

[0038] (4) Install temperature sensors near key devices (such as motors, compressors, etc.) to ensure accurate measurement of the working temperature of the devices; also install temperature sensors at different positions inside the vehicle (such as the front, middle, rear, etc.) to obtain comprehensive vehicle interior temperature information; use a data acquisition system to regularly scan and record the readings of the temperature sensors, as well as parameters such as the rotational speed, gear position, and power of the compressor; at the same time, record the real-time environmental state variables (for example, external environmental parameters such as air temperature and humidity) to consider their impact on the vehicle interior temperature.

[0039] (5) Import the collected data into the database, ensuring that each data point is associated with the corresponding device ID, timestamp, and other relevant parameters; clean and preprocess the data to remove outliers and duplicate data.

[0040] (6) Analyze the data in the database using statistical analysis methods (such as regression analysis, clustering analysis, etc.) to find the influence rules of different devices on the in-vehicle temperature under different working conditions; according to the analysis results, combine industry standards, passenger survey data, or expert opinions to fit the temperature ranges corresponding to different passenger comfort levels.

[0041] (7) Based on the fitted temperature ranges and passenger comfort requirements, construct an in-vehicle environment temperature regulation model; this model should be able to automatically adjust the operating parameters of in-vehicle devices according to the current passenger comfort requirements (such as set temperature, wind speed, etc.) and external environmental conditions (such as air temperature, humidity, etc.) to achieve the best thermal comfort.

[0042] (8) Integrate the constructed regulation model into the vehicle's control system to achieve the function of automatically regulating the in-vehicle environment temperature; during the actual operation of the vehicle, continuously monitor and record data such as in-vehicle temperature, device operating status, and passenger comfort feedback; thus, the required in-vehicle environment temperature can be determined according to user comfort, and then the static TEC can be calculated using this in-vehicle environment temperature.

[0043] In this embodiment, calculate the dynamic TEC temperature according to the in-vehicle environment temperature and the in-vehicle set temperature, then calculate the compensation value of the dynamic TEC temperature according to the temperature of the heat exchanger under the current temperature change working condition and the in-vehicle environment temperature, and finally calculate the target TEC temperature according to the following formula: Target TEC = Static TEC + Dynamic TEC + Dynamic TEC compensation value.

[0044] In this embodiment, according to the specific needs and treatment requirements of the patient, determine the set value of the breathing point temperature (user-set temperature), use a temperature sensor to monitor the current temperature of the breathing point, and adjust the heating power or cooling power of the TEC according to the obtained target TEC temperature, so as to be able to control the temperature of the internal breathing point to reach the target temperature control range within a short time under the temperature change working condition (changing set temperature). In this embodiment, the variable temperature regulation method of the air conditioning equipment provided in the above embodiment is applied to a direct heat pump air conditioning system installed in scenarios including but not limited to vehicles, homes, or aircraft.

[0045] The embodiment of the present invention provides a variable temperature adjustment method for an air conditioning device. The target heat exchanger is determined through the variable temperature working condition type of a direct heat pump air conditioning system, and the dynamic TEC temperature is obtained based on the in-vehicle environment temperature and the in-vehicle set temperature of the vehicle. The compensation value of the dynamic TEC temperature is obtained based on the temperature of the target heat exchanger and the in-vehicle environment temperature. Finally, the target TEC temperature is determined based on the static TEC temperature, the dynamic TEC temperature, and the compensation value of the dynamic TEC temperature, so as to adjust the heating capacity or refrigerating capacity of the target heat exchanger. By increasing the difference between the evaporation temperature or the internal cooling temperature and the in-vehicle temperature sensor to compensate for the dynamic Tec value, the variable temperature rate caused by the slow response of the in-vehicle temperature sensor is improved, and thus the efficiency of air conditioning heating or refrigeration is improved.

[0046] In some embodiments, the variable temperature working condition type is a heating working condition; obtaining the dynamic thermoelectric cooler (TEC) temperature based on the in-vehicle environment temperature and the in-vehicle set temperature of the vehicle includes: calculating the difference between the in-vehicle set temperature and the in-vehicle environment temperature to obtain the dynamic TEC temperature.

[0047] The following takes Figure 2 the shown direct heat pump air conditioning system as an example to illustrate the heating or refrigeration adjustment of different variable temperature working conditions.

[0048] Figure 2 is a schematic structural diagram of the direct heat pump air conditioning system provided by the present invention. In Figure 2 the shown embodiment, the outdoor environment temperature is detected by an outdoor temperature sensor to provide real-time data of the external climate for the system, the humidity data is detected by a sunlight humidity sensor installed indoors, and comprehensive information about the environmental conditions is provided; a temperature and pressure sensor I is used to monitor the temperature and pressure of the serial port (COM) in different states, a temperature and pressure sensor II is used to monitor the temperature and pressure of the internal condenser in different states, and a temperature and pressure sensor III is used to monitor the temperature and pressure of the battery cooler in different states; a temperature sensor I monitors the temperature of the outdoor heat exchanger in different states, and a temperature sensor II monitors the temperature of the evaporator in different states; electronic expansion valves I, II, and III are respectively used for the adjustment of the refrigeration and heating modes, that is, to control the refrigerant flow rate entering the evaporator, so that it evaporates rapidly under low pressure and absorbs heat; a gas-liquid separator ensures that the refrigerant entering the compressor is in a pure gas state to prevent the liquid refrigerant from damaging the compressor; a wind heating PTC is set as an auxiliary heater, which can provide additional heat under extremely cold conditions; stop valves (including stop valve II and three-way stop valve) are set to control the pipeline flow rate and cut off the pipeline.

[0049] In this embodiment, the body control module is connected to the sunlight humidity sensor, and is used to control the on / off state of the sunlight humidity sensor and collect sensor data. The vehicle controller interacts with the body controller and the air-conditioning controller respectively through the gateway. At the same time, the air-conditioning controller is connected to the serial port (COM) through the air-conditioning panel.

[0050] In this embodiment, when the current temperature-changing working condition type of the air-conditioning system is the heating working condition, the in-vehicle environment temperature T is recorded by the temperature sensor I. 车内 , the static TEC temperature is calculated according to the data recorded by the sunlight humidity sensor, and when the evaporator absorbs the heat of the outdoor environment, T is recorded according to the temperature sensor I. 蒸发 ; The temperature to be adjusted, that is, the in-vehicle set temperature T, is obtained according to the user input instruction. 设定 ; The dynamic TEC temperature under the heating working condition is calculated according to the following formula: Dynamic TEC = T 设定 -T 车内 .

[0051] When the temperature-changing working condition type is the heating working condition, the heat exchanger is the evaporator; obtaining the compensation value of the dynamic TEC temperature based on the temperature of the target heat exchanger and the in-vehicle environment temperature includes: calculating the absolute value of the difference between the temperature of the evaporator and the in-vehicle environment temperature to obtain the compensation value of the dynamic TEC temperature.

[0052] In this embodiment, the compensation value of the dynamic TEC under the heating working condition is calculated according to the following formula: Dynamic TEC compensation value = |T 蒸发 -T 车内 |.

[0053] In this embodiment, after obtaining the above dynamic TEC compensation value, the target TEC temperature under the heating working condition is calculated according to the following formula: Target TEC = Static TEC + Dynamic TEC + Dynamic TEC compensation value.

[0054] Finally, according to the specific needs and treatment requirements of the patient, the set value (user set temperature) of the breathing point temperature is determined. The temperature sensor is used to monitor the current temperature of the breathing point, and the heating power of the TEC is adjusted according to the target TEC temperature under the above heating working condition, so that the air-conditioning system can control the temperature of the internal breathing point to rise to the in-vehicle set temperature within a short time under the heating working condition.

[0055] The embodiment of the present invention provides a method for variable temperature regulation of an air conditioning device. When the variable temperature working condition type is a heating working condition and the heat exchanger is an evaporator, a dynamic TEC temperature is obtained according to the difference between the set temperature inside the vehicle and the ambient temperature inside the vehicle, and a compensation value of the dynamic TEC temperature is obtained according to the absolute value of the difference between the temperature of the evaporator and the ambient temperature inside the vehicle. Then, the target TEC temperature under the heating working condition is calculated to achieve a rapid response of air conditioning heating and improve the air conditioning heating efficiency.

[0056] In some embodiments, the variable temperature working condition type is a cooling working condition; obtaining the dynamic thermoelectric cooler (TEC) temperature according to the ambient temperature inside the vehicle and the set temperature inside the vehicle of the vehicle includes: calculating the difference between the ambient temperature inside the vehicle and the set temperature inside the vehicle to obtain the dynamic TEC temperature.

[0057] In Figure 2 In the shown embodiment, the high-temperature and high-pressure gas enters the internal condenser, where it releases heat to the external environment and condenses into a high-pressure liquid; in the evaporator, the refrigerant changes from a liquid state to a gaseous state, absorbing the heat of the air inside the vehicle to achieve a refrigeration effect.

[0058] In this embodiment, when the current variable temperature working condition type of the air conditioning system is a cooling working condition, the ambient temperature inside the vehicle T 车内 is recorded by the temperature sensor I, the static TEC temperature is calculated according to the data recorded by the sunlight humidity sensor, and T 内冷 is recorded by the temperature and pressure sensor II; the temperature to be adjusted, that is, the set temperature T 设定 inside the vehicle, is obtained according to the user input instruction; the dynamic TEC temperature under the heating working condition is calculated according to the following formula: Dynamic TEC = T 内冷 - T 设定 .

[0059] When the variable temperature working condition type is a cooling working condition and the heat exchanger is an internal condenser; obtaining the compensation value of the dynamic TEC temperature based on the temperature of the target heat exchanger and the ambient temperature inside the vehicle includes: calculating the absolute value of the difference between the temperature of the internal condenser and the ambient temperature inside the vehicle to obtain the compensation value of the dynamic TEC temperature.

[0060] In this embodiment, the compensation value of the dynamic TEC under the cooling working condition is calculated according to the following formula: Dynamic TEC compensation value = |T 内冷 - T 车内 |.

[0061] In this embodiment, after obtaining the above dynamic TEC compensation value, the target TEC temperature under the cooling working condition is calculated according to the following formula: Target TEC = Static TEC + Dynamic TEC + Dynamic TEC compensation value.

[0062] Finally, according to the specific needs and treatment requirements of the patient, determine the set value of the breathing point temperature (user-set temperature), use the temperature sensor to monitor the current temperature of the breathing point, and adjust the cooling power of the TEC according to the target TEC temperature under the above cooling conditions, so that the air-conditioning system can control the temperature of the internal breathing point to drop to the set temperature inside the vehicle within a short time under the cooling conditions.

[0063] The embodiment of the present invention provides a variable temperature adjustment method for an air-conditioning device. When the variable temperature working condition type is a cooling condition and the heat exchanger is an internal condenser, a dynamic TEC temperature is obtained according to the difference between the vehicle interior environment temperature and the vehicle interior set temperature, and a compensation value of the dynamic TEC temperature is obtained according to the absolute value of the difference between the temperature of the internal condenser and the vehicle interior environment temperature, and then the target TEC temperature under the cooling condition is calculated to achieve a rapid response of air-conditioning refrigeration and improve the air-conditioning refrigeration efficiency.
