Abstract
Description
Technical Field
[0001] This application relates to the field of air conditioning technology, and in particular to a control method for a parking air conditioner, a parking air conditioner, and a computer storage medium. Background Technology
[0002] With the development of technology and the gradual improvement of living standards, people's demands for life are also increasing. With the trend of global warming, extreme high-temperature weather in summer is becoming more frequent. In the hot summer or cold winter, people need air conditioning to regulate the temperature of their environment, so that the human body can be in a comfortable environment.
[0003] With the development of the transportation industry, trucks, RVs, buses, and other vehicles are equipped with onboard air conditioning. Traditional onboard air conditioning relies on the vehicle's engine to drive a mechanical compressor or on the engine generating electricity to power the compressor. However, when the vehicle is off, if the driver or passengers need to turn on the air conditioning while resting, the engine must be restarted, consuming fuel to power the air conditioning and resulting in energy waste. Therefore, parking air conditioners have become a common temperature control tool in trucks, vans, and construction machinery, responsible for providing a comfortable temperature environment for drivers and passengers in long-haul trucks. Compared to traditional onboard air conditioning, parking air conditioners do not rely on the vehicle's engine; instead, they are powered directly by the vehicle's battery, allowing them to operate even when the vehicle is off, thus saving energy.
[0004] In related technologies, controlling a parking air conditioner requires manual operation by the driver, including setting temperature parameters. Once set, the temperature remains fixed, increasing operating costs and impacting user comfort. Furthermore, most parking air conditioners are powered by batteries, which can deplete over time, leading to increased energy consumption and shortening battery life. Summary of the Invention

[0007] The compressor voltage information includes the current voltage and shutdown voltage of the compressor. The in-vehicle ambient temperature information includes the sampled temperature and target temperature. The compressor operating frequency is calculated based on the voltage information and the in-vehicle temperature information, including: obtaining the voltage difference between the current voltage and the shutdown voltage; obtaining the first average value of the difference between the sampled temperature and the target temperature in the current time period, and the second average value of the difference between the sampled temperature and the target temperature in the previous time period; and calculating the compressor operating frequency based on the voltage difference and the first and second average values.
[0008] The calculation of the compressor's operating frequency based on the voltage difference and the first and second average values includes: converting the voltage difference into a voltage coefficient and the first average value into a temperature difference coefficient; calculating the temperature difference between the first and second average values and converting the temperature difference into a temperature difference change rate coefficient; and obtaining the compressor's operating frequency based on the voltage coefficient, temperature difference coefficient, and temperature difference change rate coefficient.
[0009] The process of obtaining the compressor's operating frequency based on the voltage coefficient, temperature difference coefficient, and temperature difference change rate coefficient includes: determining whether the voltage coefficient is valid; in response to the validity of the voltage coefficient, obtaining the compensation frequency based on the voltage coefficient, temperature difference coefficient, temperature difference change rate coefficient, temperature difference value, and the first average value; and determining the sum of the compressor's current operating frequency and the compensation frequency as the compressor's operating frequency.
[0010] The compensation frequency is obtained based on the voltage coefficient, temperature difference coefficient, temperature difference rate coefficient, temperature difference value, and first mean value. This includes: calculating the first product of the first mean value and the temperature difference coefficient, and the second product of the temperature difference rate coefficient and the temperature difference value; calculating the sum of the first product and the second product, and multiplying the sum by the voltage coefficient to obtain the compensation frequency.
[0011] The method of obtaining the compressor's operating frequency based on the voltage coefficient, temperature difference coefficient, and temperature difference change rate coefficient also includes: in response to the voltage coefficient being invalid, obtaining a compensation frequency based on the temperature difference coefficient, temperature difference change rate coefficient, temperature difference value, and first average value; and determining the sum of the compressor's current operating frequency and the compensation frequency as the compressor's operating frequency.
[0012] The compensation frequency is obtained based on the temperature difference coefficient, the temperature difference change rate coefficient, the temperature difference value, and the first mean value, including: calculating the first product of the first mean value and the temperature difference coefficient, and the second product of the temperature difference change rate coefficient and the temperature difference value; and calculating the sum of the first product value and the second product value to obtain the compensation frequency.
[0013] The determination of whether the voltage coefficient is valid includes: calculating the first product of the first mean and the temperature difference coefficient, and the second product of the temperature difference change rate coefficient and the temperature difference; calculating the sum of the first product and the second product to obtain the determination coefficient; in response to the determination coefficient being greater than zero, the voltage coefficient is determined to be valid; in response to the determination coefficient being greater than, less than or equal to zero, the voltage coefficient is determined to be invalid.
[0014] To solve the above-mentioned technical problems, another technical solution adopted in this application is to provide a parking air conditioner, which includes a compressor and a processor. The compressor is connected to the processor, and the processor is used to control the operation of the compressor using the above-mentioned control method.
[0015] To solve the above-mentioned technical problems, another technical solution adopted in this application is to provide a computer storage medium that stores program data, which, when executed, is used to implement the above-mentioned control method.
[0016] The beneficial effects of this application are as follows: Unlike existing technologies, the control method provided in this application is applied to a parking air conditioner. The parking air conditioner contains a compressor and acquires the compressor's voltage information and the vehicle's interior ambient temperature information. Based on the voltage and temperature information, the operating frequency of the compressor is calculated, and the compressor is controlled to operate at that frequency. Compared to conventional control methods, this application's method of calculating the compressor's operating frequency based on the compressor's battery voltage and the vehicle's interior ambient temperature after the parking air conditioner has been running allows for real-time variable frequency adjustment of the air conditioner compressor and controls it to operate at the specified frequency. This results in more efficient operation of the parking air conditioner, reducing compressor energy loss, decreasing the probability of battery depletion, extending battery life, increasing energy efficiency, and improving user comfort.

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0030] In this document, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " generally indicates that the preceding and following related objects have an "or" relationship. Furthermore, "many" in this document means two or more. Moreover, the term "at least one" in this document means any combination of at least two of any one or more of a plurality of objects. For example, including at least one of A, B, and C can mean including any one or more elements selected from the set consisting of A, B, and C.
[0031] The control method provided in this application is mainly applied to a parking air conditioner. The control method can be applied to a server or to a system in which a server and terminal devices cooperate. Accordingly, all parts involved in the control method, such as units, subunits, modules, and submodules, can be entirely located in the server, or they can be separately located in the server and terminal devices.
[0032] Furthermore, the aforementioned server can be either hardware or software. When the server is hardware, it can be implemented as a distributed server cluster consisting of multiple servers, or as a single server. When the server is software, it can be implemented as multiple software programs or software modules, such as software or software modules used to provide distributed servers, or as a single software program or software module; no specific limitation is made here. In some possible implementations, the control method of this application embodiment can be implemented by a processor calling computer-readable instructions stored in memory.
[0033] The control method provided in this application is mainly applied to the control of refrigeration equipment such as parking air conditioners that are powered by batteries. By periodically identifying the working voltage of the compressor battery of the parking air conditioner, and adjusting the operating frequency of the air conditioner compressor in real time based on the working voltage and the working effect of the parking air conditioner, i.e. the temperature change of the air conditioner's working environment, the compressor operating frequency is adjusted according to the battery voltage.
[0034] Current methods for controlling parking air conditioners primarily rely on the driver manually adjusting the compressor frequency to a fixed setting. Unlike household inverter air conditioners, parking air conditioners cannot utilize full-frequency inverter technology. Furthermore, when the battery voltage is low, high-frequency compressor operation can cause a rapid drop in battery power, leading to battery depletion. Therefore, this application provides a control method for a parking air conditioner, and the technical solution adopted in this application will be described in detail below.
[0035] See Figure 1 and Figure 2 , Figure 1This is a flowchart illustrating the first embodiment of the control method provided in this application. Figure 2 This is a flowchart illustrating the control method applied in the parking air conditioner provided in this application.
[0036] Step 11: Obtain the compressor voltage information and the vehicle interior ambient temperature information respectively.
[0037] Specifically, the compressor voltage information includes the compressor's current voltage and shutdown voltage, and the vehicle interior ambient temperature information includes the sampling temperature and target temperature.
[0038] Specifically, after receiving the start command from the user, the parking air conditioner starts up, acquiring the compressor's current operating voltage Us and the parking air conditioner's shutdown voltage Ut, which is set to protect the battery. The shutdown voltage can be determined based on the battery capacity used by the parking air conditioner and is not specified here.
[0039] Specifically, after collecting the compressor's current operating voltage Us and shutdown voltage Ut, the parking air conditioner will also obtain the sampling temperature Ta of the current operating environment of the parking air conditioner and the target temperature Ts set by the user.
[0040] Step 12: Calculate the compressor's operating frequency based on voltage information and in-vehicle ambient temperature information.
[0041] Optionally, this embodiment can be achieved through, as follows: Figure 3 The method shown implements step 12. Figure 3 The control method provided in this application Figure 1 A flowchart illustrating a specific implementation of step 12 in this embodiment. Specifically, the method in this embodiment includes steps 31 to 32.
[0042] Step 31: Obtain the voltage difference between the current voltage and the shutdown voltage.
[0043] Specifically, the voltage difference ∆U is the difference between the compressor's current operating voltage Us and the parking air conditioner's shutdown voltage Ut, which is used to protect the battery, i.e., Us-Ut.
[0044] Step 32: Obtain the first average value of the difference between the sampled temperature and the target temperature in the current time period, and the second average value of the difference between the sampled temperature and the target temperature in the previous time period.
[0045] Specifically, the parking air conditioner acquires the current interior temperature Tb after a compressor operation interval N. When the parking air conditioner is in cooling mode, the first mean is the average difference between the current interior temperature and the user-set target temperature Ts, i.e., Tb-Ts. The second mean is the average difference between the interior temperature Ta collected in the previous time period and the user-set target temperature, i.e., Ta-Ts. When the parking air conditioner is in heating mode, the first mean ∆T1 is Ts-Tb, and the second mean ∆T2 is Ts-Ta.
[0046] Step 33: Calculate the compressor's operating frequency based on the voltage difference, the first mean, and the second mean.
[0047] In one embodiment of this application, the parking air conditioner can calculate the compressor's operating frequency by converting the voltage difference, the first average value, and the second average value into a voltage coefficient, a temperature difference coefficient, and a temperature difference change rate coefficient.
[0048] Optionally, this embodiment may employ the following: Figure 4 The method shown implements step 33. Figure 4 The control method provided in this application Figure 3 The specific implementation of step 33 in the embodiment is shown in the flowchart of an embodiment. The method of this embodiment specifically includes steps 41 to 43.
[0049] Step 41: Convert the voltage difference into a voltage coefficient and the first mean value into a temperature difference coefficient.
[0050] In one embodiment of this application, the parking air conditioner can be... Figure 5 and Figure 6 The conversion diagram illustrates the coefficient conversion between the voltage difference and the first mean. (See attached diagram.) Figure 5 and Figure 6 , Figure 5 This is a schematic diagram illustrating an embodiment of the control method provided in this application that converts voltage difference into voltage coefficient. Figure 6 This is a schematic diagram illustrating an embodiment of the control method provided in this application that converts the first mean value into a temperature difference coefficient.
[0051] Specifically, the parking air conditioner can be adjusted according to... Figure 5 The correspondence between voltage difference and voltage coefficient converts the voltage difference into a voltage coefficient. For example... Figure 5 As shown, the voltage coefficient A ranges from [0,1] and can be set according to the capacity of the vehicle's battery. When the voltage difference ∆U is between 0 and 1, the voltage coefficient A is 0; when the voltage difference ∆U is between 1 and 2, the voltage coefficient is 0.2. Similarly, when the voltage difference ∆U is greater than 5, the voltage coefficient A is 1.
[0052] Specifically, the parking air conditioner can be adjusted according to... Figure 6The correspondence between the first mean and the temperature difference coefficient is to convert the first mean into the temperature difference coefficient. For example... Figure 6 As shown, the range of values for the temperature difference coefficient B can be set according to the size of the cab space and the different refrigeration systems. When the temperature difference ∆T is between -0.5 and 0.5, the temperature coefficient B is 0; when the temperature difference ∆T is between 0.5 and 1, the temperature coefficient B is 1, and so on. When the temperature difference ∆T is greater than 2, the temperature coefficient B is 4.
[0053] Step 42: Calculate the temperature difference between the first mean and the second mean, and convert the temperature difference into a coefficient of temperature change rate.
[0054] Specifically, the temperature difference, or the rate of change of temperature difference ∆Tc, is calculated from the difference between the temperature difference ∆TN within the current period N and the temperature difference ∆T(N-1) within the previous period N-1. After calculating the temperature difference ∆Tc between the first average ∆T1 and the second average ∆T2, the parking air conditioner further converts the temperature difference into a rate of change coefficient of temperature difference. (See also...) Figure 7 , Figure 7 This is a schematic diagram illustrating an embodiment of the control method provided in this application that converts temperature difference into a temperature difference change rate coefficient.
[0055] Specifically, the parking air conditioner can be adjusted according to... Figure 7 The correspondence between temperature difference and the coefficient of temperature change converts the temperature difference value into the coefficient of temperature change. For example... Figure 7 As shown, the range of values for the temperature difference change rate coefficient can be set according to the size of the cab space and the different refrigeration systems. When the temperature difference ∆Tc is between -0.5 and 0.5, the temperature difference change rate coefficient C is 0; when the temperature difference ∆Tc is between 0.5 and 1, the temperature difference change rate coefficient C is 0.5. When the temperature difference ∆Tc is greater than 2, the temperature difference change rate coefficient C is 2; when the temperature difference ∆Tc is between -0.5 and -1, the temperature difference change rate coefficient C is 1; and when the temperature difference ∆Tc is less than -2, the temperature difference change rate coefficient C is 4.
[0056] Step 43: Obtain the compressor's operating frequency based on the voltage coefficient, temperature difference coefficient, and temperature difference change rate coefficient.
[0057] Optionally, this embodiment may employ the following: Figure 8 The method shown implements step S43. Figure 8 illustrates the control method provided in this application. Figure 4 The flowchart of step 43 in this embodiment is shown. In this embodiment, the parking air conditioner can also determine the validity of the voltage coefficient to obtain a more accurate operating frequency for controlling the compressor.
[0058] Step 81: Determine if the voltage coefficient is valid.
[0059] Specifically, the parking air conditioner calculates the first product of the first mean value and the temperature difference coefficient, and the second product of the temperature difference change rate coefficient and the temperature difference value; the sum of the first and second products is calculated to obtain the determination coefficient. That is, the determination coefficient F = ∆T*B + ∆Tc*C. If the determination coefficient is greater than zero, i.e., ∆T*B + ∆Tc*C > 0, the parking air conditioner determines that the voltage coefficient A is valid; if the determination coefficient is greater than, less than, or equal to zero, i.e., ∆T*B + ∆Tc*C ≤ 0, the voltage coefficient is determined to be invalid. If the voltage coefficient A is valid, proceed to step 82; otherwise, proceed to step 83.
[0060] Step 82: Obtain the compensation frequency based on the voltage coefficient, temperature difference coefficient, temperature difference rate coefficient, temperature difference value, and the first mean value.
[0061] Specifically, the parking air conditioner calculates the first product of the first mean and the temperature difference coefficient, and the second product of the temperature difference change rate coefficient and the temperature difference. After obtaining the first product and the second product, it calculates the sum of the first product and the second product, and multiplies the sum by the voltage coefficient to obtain the compensation frequency.
[0062] Step 83: Obtain the compensation frequency based on the temperature difference coefficient, the temperature difference change rate coefficient, the temperature difference value, and the first mean value.
[0063] Specifically, if the voltage coefficient is invalid, the parking air conditioner responds to the invalid voltage coefficient by obtaining a compensation frequency based on the temperature difference coefficient, the temperature difference rate coefficient, the temperature difference value, and the first mean value.
[0064] The parking air conditioner calculates the first product of the first mean and the temperature difference coefficient, and the second product of the temperature difference change rate coefficient and the temperature difference; the sum of the first product and the second product is then calculated to obtain the compensation frequency.
[0065] Specifically, when the voltage coefficient is effective, the compensation frequency F = (∆T*B + ∆Tc*C)*A; when the voltage coefficient is ineffective, the compensation frequency F = ∆T*B + ∆Tc*C.
[0066] Step 84: Determine the compressor's operating frequency as the sum of its current operating frequency and the compensation frequency.
[0067] Specifically, after the parking air conditioner determines that the sum of the current operating frequency and the compensation frequency of the compressor is the operating frequency of the compressor, it will also control the air conditioning compressor to operate at the operating frequency.
[0068] Step 13: Control the compressor to operate at the operating frequency.
[0069] Optionally, the parking air conditioner can periodically acquire the battery voltage of the air conditioner compressor at time intervals N, thereby achieving periodic adjustment of the operating frequency of the air conditioner compressor based on the battery voltage. The parking air conditioner in the control method involved in this application can also be any battery-powered refrigeration device, such as a motorhome air conditioner, an engineering vehicle air conditioner, etc., and is not limited here.
[0070] The control method provided in this application is described below with a complete embodiment. A parking air conditioner is installed in a truck. When the parking air conditioner starts operating, the current interior temperature is obtained as 30 degrees Celsius, and the compressor operating voltage is 25V. The driver turns on the air conditioner and sets the target temperature in cooling mode to 24 degrees Celsius. The battery software corresponding to this compressor has a protection voltage set to 21.5V, and the compressor's current operating frequency is 50Hz. After one cycle N, the interior temperature is 29 degrees Celsius.
[0071] The calculated voltage difference ∆U = 25 - 21.5 = 3.5V falls within the range of 3~4V. According to... Figure 4 The corresponding relationship is given, with voltage coefficient A taken as 0.6; the first mean value ∆T1 = 29 - 24 = 5 after one cycle N is calculated, and the second mean value ∆T2 = 30 - 24 = 6 corresponding to the initial temperature is calculated. The first mean value ∆T1 = 5 > 2 is obtained, according to... Figure 5 The corresponding relationship is ∆T=∆T1=5, and the temperature difference coefficient B is taken as 4; thus, the temperature difference value ∆Tc=∆T1-∆T2=5-6=-1, according to... Figure 6 The corresponding relationship is that the coefficient of temperature difference change rate C takes the value of 2.
[0072] The judgment coefficient for voltage coefficient A is calculated as F = ∆T1*B + (∆T1 - ∆T2)*C = 5*4 + (-1)*2 = 18. If F is greater than 0, then voltage coefficient A is valid. The compensation frequency is F*A = 18*0.6 = 10.8, rounded down to 11. The compressor operating frequency is the current frequency + the compensation frequency = 50 + 11 = 61. Therefore, after one cycle N, the compressor operates at 61Hz.
[0073] Unlike existing technologies, the control method provided in this application is applied to a parking air conditioner. The parking air conditioner contains a compressor and acquires the compressor's voltage information and the vehicle's interior ambient temperature information. Based on the voltage and temperature information, it calculates the compressor's operating frequency and controls the compressor to operate at that frequency. Compared to conventional control methods, this application's method of calculating the compressor's operating frequency based on the compressor's battery voltage and the vehicle's interior ambient temperature after the parking air conditioner has been running allows for real-time variable frequency adjustment of the air conditioner compressor and controls it to operate at the designated frequency.
