[0024] Example 1
[0025] According to an embodiment of the present invention, an air conditioning control method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.
[0026] Figure 1 is a flow chart of an air conditioning control method according to an embodiment of the present invention. Figure 1 As shown, the method includes the following steps:
[0027] Step S102: obtaining a first temperature outside the vehicle where the air conditioner is located.
[0028] The first temperature in the above steps can be the current temperature of the vehicle's external environment obtained by the temperature sensor after the air conditioner is started, wherein the temperature sensor can be installed on the outside of the vehicle for real-time temperature collection. The type of temperature sensor is not limited here; the type of vehicle in the above steps can be classified according to passenger cars and trucks. For example, passenger cars can be trains, cars, subways, etc., and trucks can be flat cars, open cars, covered cars, tank cars, insulated cars, etc. There is no limitation on the type of vehicle here.
[0029] Step S104: determining whether the first temperature is lower than a preset temperature.
[0030] The preset temperature in the above steps can be the starting temperature when the air conditioner enters a low-temperature heating working mode. The specific value of the starting temperature can be determined based on actual conditions. Furthermore, it may be affected by many factors. The value of the preset temperature may be different in different environments. For example, the preset temperature on plateaus and plains may be different.
[0031] In an optional embodiment, if Figure 2As shown, X is the set starting temperature of the low-temperature heating operation mode. If the first temperature Te is less than X°C, the low-temperature heating operation mode is entered; if the first temperature Te is greater than X°C, the normal heating operation mode is entered.
[0032] Step S106 : When the first temperature is lower than a preset temperature, the air supply volume of the air conditioner is controlled based on the air intake pressure of the air conditioner.
[0033] In the process of controlling the air supply volume of the air conditioner based on the air intake pressure of the air conditioner in the above steps, the preset pressure value interval to which the currently monitored air intake pressure belongs can be determined first, wherein the preset pressure value interval can be a plurality of intervals composed of a plurality of already determined preset pressure values, and the preset pressure values can be obtained through experiments; then, the air supply volume corresponding to each interval can be determined according to the already determined preset pressure value interval; finally, the air supply volume corresponding to the air intake pressure can be determined according to the currently monitored air intake pressure, and the air supply of the air conditioner is performed by controlling the relevant actuator through the determined air supply volume, wherein the actuator can be a control valve.
[0034] In an optional embodiment, a first temperature of the vehicle's external environment is first obtained, and it is determined whether the temperature is lower than a preset temperature. If the obtained first temperature is lower than the preset temperature, the air conditioner enters a low-temperature operation mode. After entering the operation mode, multiple preset pressure value intervals are determined by multiple preset pressure values, and each preset pressure value interval has a one-to-one corresponding air supply volume. At this time, the air supply volume of the air conditioner can be determined by the preset pressure value interval to which the pressure value of the monitored intake pressure belongs. Under the interaction between the air supply volume and the intake pressure, the interaction can increase the condensation pressure by reducing the air supply volume in a low-temperature environment, thereby affecting the increase in the intake pressure, thereby enabling the air conditioner to operate continuously and stably in a low-temperature environment.
[0035] In an embodiment of the present invention, a first temperature outside the vehicle where the air conditioner is located is first acquired, and then a determination is made as to whether the first temperature is lower than a preset temperature. If the first temperature is lower than the preset temperature, the air supply volume of the air conditioner is controlled based on the air conditioner's intake pressure. By determining whether the first temperature is lower than the preset temperature and controlling the air supply volume of the air conditioner based on the air conditioner's intake pressure, the air conditioner is further adapted to low-temperature operating conditions during operation in low-temperature environments, achieving stable operation in even lower temperature environments. This achieves the technical effect of stable operation of the air conditioner in low-temperature environments, thereby resolving the technical problem of poor operational stability of heat pump air conditioners in related technologies when operating in low-temperature environments.
[0036] Optionally, controlling the air supply volume of the air conditioner based on the air intake pressure of the air conditioner includes: determining the preset pressure value interval to which the pressure value of the intake pressure belongs; determining the target air supply volume corresponding to the preset pressure value interval; and controlling the air supply volume of the air conditioner to be the target air supply volume.
[0037] The target air supply volume in the above steps may be the unique corresponding air supply volume determined by the preset pressure value interval to which the suction pressure at the current moment belongs after determining the interval.
[0038] In an optional embodiment, Figure 2 As shown, when the first temperature is lower than the preset temperature, that is, when Te is less than X℃, XQ (that is, the pressure value of the above-mentioned suction pressure) is monitored. When XQ≥P1, the air supply volume is not adjusted, and the target air supply volume can be L0; when P2≤XQ<P1, the target air supply volume is L1; when P3≤XQ<P2, the target air supply volume is L2; when XQ<P3, the target air supply volume is L3, among which P1>P2>P3, L0≥L1≥L2≥L 3, P1, P2, and P3 are the preset pressure values mentioned above. The predicted pressure value intervals composed of P1, P2, and P3 are: XQ≥P1, P2≤XQ<P1, P3≤XQ<P2, and XQ<P3, respectively. The number of preset pressure values can be n, for example, P1, P2, P3…Pn. Therefore, the number of preset pressure value intervals that can be determined can be n+1. Each preset pressure value interval corresponds to an air supply volume, so there are a total of n+1 air supply volumes.
[0039] Optionally, determining the target air supply volume corresponding to the preset pressure value interval includes: determining a first fresh air volume based on the passenger capacity of the vehicle; determining a second fresh air volume based on the first temperature; obtaining the maximum fresh air volume between the first fresh air volume and the second fresh air volume; and determining the target air supply volume based on the maximum fresh air volume.
[0040] The first fresh air volume in the above steps can be the required fresh air volume calculated based on the passenger capacity; the second fresh air volume can be the required fresh air volume when operating at low temperature, that is, when the first temperature is lower than the preset temperature; the maximum fresh air volume can be obtained by comparing the first fresh air volume and the second fresh air volume, and determining that the larger air volume between the two is the maximum fresh air volume.
[0041] In an optional embodiment, LX=max{LXn, LXm}, where LX represents the maximum fresh air volume; LXn represents the fresh air volume corresponding to the required air supply volume Ln in the low-temperature operation mode; LXm represents the required fresh air volume adjusted according to the passenger capacity; L represents the target air supply volume, and the air supply volume corresponding to the larger fresh air volume closest to LX is taken.
[0042] Optionally, determining the target air supply volume based on the maximum fresh air volume includes: obtaining a preset corresponding relationship, wherein the preset corresponding relationship is used to characterize the corresponding relationship between the fresh air volume and the supply air volume; and determining the target air supply volume based on the maximum fresh air volume and the preset corresponding relationship.
[0043] The preset correspondence in the above steps may be a correspondence table established based on test data obtained in advance in the laboratory.
[0044] In an optional embodiment, the preset correspondence relationship can be represented by a target air supply control table, as shown in Table 1:
[0045] Table 1
[0046] Fresh air volume Air supply volume Fresh air valve opening Return air valve opening Fresh air volume LX0 Air supply volume L0 <![CDATA[Fresh air valve fully open (n0 = 0)]]> <![CDATA[Close for m0 seconds after the return air valve is fully open]]> Fresh air volume LX1 Air supply volume L1 <![CDATA[The fresh air valve closes for n1 seconds after being fully opened]]> <![CDATA[Close for m1 seconds after the return air valve is fully open]]> Fresh air volume LX2 Air supply volume L2 <![CDATA[The fresh air valve closes for n2 seconds after being fully opened]]> <![CDATA[After the return air valve is fully open, close for m2 seconds]]> Fresh air volume LX3 Air supply volume L3 <![CDATA[The fresh air valve closes for n3 seconds after being fully opened]]> <![CDATA[After the return air valve is fully open, it closes for m3 seconds]]> … … … … Fresh air volume LXn Air supply volume Ln <![CDATA[After the fresh air valve is fully opened, it closes for n n seconds]]> <![CDATA[After the return air valve is fully opened, close it for m n seconds]]>
[0047] According to the contents in the table, there is a one-to-one correspondence between multiple fresh air volumes and multiple supply air volumes. As shown in Table 1, the fresh air volumes LX0, LX1, LX2, LX3…LXn correspond one-to-one to the supply air volumes L0, L1, L2, L3, and Ln, respectively. Based on this one-to-one correspondence, the maximum fresh air volume can be compared with Table 1, and the fresh air volume closest to the maximum in the table is taken as the final fresh air volume; the supply air volume corresponding to the final fresh air volume is the target supply air volume.
[0048] Optionally, controlling the air supply volume of the air conditioner to be a target air supply volume includes: determining a first opening of the fresh air valve and a second opening of the return air valve of the air conditioner based on the target air supply volume, wherein the first opening is used to represent the first time the fresh air valve is closed after being fully opened; the second opening is used to represent the second time the return air valve is closed after being fully opened, controlling the fresh air valve based on the first opening, and controlling the return air valve based on the second opening.
[0049] The first opening in the above steps can be the time required to execute the valve closing action after the opening of the fresh air valve is fully opened in the process of controlling the air conditioning supply after determining the target air supply volume, that is, the first time, and the second opening can be the time required to execute the valve closing action after the opening of the return air valve is fully opened in the process of controlling the air conditioning supply, that is, the second time.
[0050] In an optional embodiment, still taking Table 1 as an example, the fresh air volumes LX0, LX1, LX2, LX3...LXn and the supply air volumes L0, L1, L2, L3, Ln also correspond to the fresh air valve openings, that is, the first openings n0, n1, n2, n3...n n and the return air valve opening, that is, the second opening m0, m1, m2, m3...m n , where n0, n1, n2, n3…n n , m0, m1, m2, m3…m nIndicates the time it takes for the fresh air valve and the return air valve to close after they are fully opened. For example, when the fresh air volume is determined to be LX0, the corresponding target air supply volume is determined to be L0. The valve openings of the fresh air valve and the return air valve are controlled according to the target air supply volume. As shown in Table 1, n0 is 0 seconds, indicating that the opening of the fresh air valve at this time is the valve opening 0 seconds after the valve is fully opened. The same is true for m0, which will not be described here. It should be noted that n0, n1, n2, n3…n n , m0, m1, m2, m3…m n The corresponding time needs to be calculated based on the actual situation. Therefore, according to the preset relationship in Table 1, the target fresh air volume can be determined to control the first opening and the second opening to be adjusted to the corresponding set values to achieve a rational air supply state.
[0051] Optionally, before obtaining the current temperature outside the vehicle where the air conditioner is located, the method further includes: when a heating signal is received, determining whether the air conditioner is started for the first time; if the air conditioner is not started for the first time, obtaining the current temperature.
[0052] In the above steps, when a heating signal is received, it is determined whether the air conditioner is started for the first time. If the air conditioner is started for the first time, a low-temperature heating start mode judgment is first performed. If the air conditioner is not started for the first time, the low-temperature heating operation mode judgment is entered.
[0053] Optionally, when the air conditioner is started for the first time, the method also includes: obtaining a second temperature outside the vehicle; determining a preset temperature range to which the second temperature belongs; determining a target delay time corresponding to the preset temperature range; controlling the condensing fan and compressor of the air conditioner to start, and after waiting for the target delay time, controlling the air supply fan of the air conditioner to start.
[0054] The second temperature in the above steps may be the current temperature of the vehicle's external environment collected by the temperature sensor when the air conditioner is started for the first time; the preset temperature interval may be multiple intervals determined by multiple preset temperature values, and the target delay time may be the startup delay time of the air conditioner blower that is uniquely corresponding to the preset temperature interval to which the second temperature belongs, wherein the specific preset temperature value, preset temperature interval, and target delay time are related to the system design of the specific unit.
[0055] In an optional embodiment, Figure 3For illustration, when the air conditioner is initially started, a determination is first made as to whether the second temperature is less than A°C, where A represents the first low-temperature range. If the second temperature is less than this value, there is a risk of low-pressure protection during the heating startup process, requiring a delayed start of the blower. The startup delay is a seconds (i.e., the target delay time corresponding to the first low-temperature range). The specific values of A and a depend on the system design of the specific unit (e.g., evaporation area, refrigerant charge, compressor capacity, etc.). Furthermore, B represents the value of the second low-temperature range. If B < A, i.e., the second temperature is lower, then a longer time of b seconds (i.e., the target delay time corresponding to the second low-temperature range) is required to establish a high-pressure environment. If the second temperature is greater than A°C, the vehicle's external temperature at this time will not affect the air conditioner's heating startup. Therefore, the target delay time corresponding to this temperature range is 0 seconds, meaning that no delayed start of the blower is required. The values of A, B, a, and b can be determined through laboratory simulation tests.
[0056] It should be noted that the third, fourth, ... intervals, and c, d, ... values can be set according to actual needs.
[0057] Optionally, while waiting for the target delay time, the method also includes: obtaining the high pressure and low pressure of the air conditioner; when the high pressure is greater than the first preset pressure, or the low pressure is less than the second preset pressure, controlling the blower to start.
[0058] The high pressure and low pressure in the above steps can be monitored by setting a high pressure sensor and a low pressure sensor. If the high pressure is detected to be greater than the first preset pressure, or the low pressure is less than the second preset pressure, the blower exits the delayed start and starts air conditioning.
[0059] In an optional embodiment, when a high pressure sensor and a low pressure sensor are provided, a pressure exit mode may be set, P 高 >P 高设 , or P 低 <P 低设 , the blower exits the delay and starts to start.
[0060] The following combination Figure 2 and Figure 3 A preferred embodiment of the present invention is described in detail.
[0061] In the case of low-temperature operation of a subway heat pump air-conditioning unit, the air-conditioning is first started in a low-temperature environment. When a heating demand signal is received, it is necessary to determine whether the current state of the air-conditioning is the first start-up after shutdown. If it is not the first start-up, the low-temperature heating operation mode is entered. If it is determined to be the low-temperature start-up mode after the judgment, first determine whether the second temperature is less than the first low-temperature interval. If not, the air-conditioning is started normally, that is, the supply fan, condensing fan, and compressor are started in sequence; if so, determine whether the second temperature is less than the second low-temperature interval. If not, start the condensing fan, compressor, and supply fan in sequence according to the target delay time a second corresponding to the preset temperature interval. If so, start the condensing fan, compressor, and supply fan in sequence according to the target delay time b seconds corresponding to the preset temperature interval, and so on. Among them, the condensing fan generally refers to the outdoor fan, and the supply fan refers to the indoor fan. After the air conditioner is successfully started in a low-temperature environment, it is determined whether the first temperature is lower than the preset temperature. If not, it enters the normal heating operation mode. If so, the target air supply volume corresponding to each interval is determined according to the preset pressure value interval to which the suction pressure belongs. According to the determined target air supply volume, the air conditioner is controlled to achieve an ideal air supply state in the low-temperature environment, so that the air conditioner operates stably in the low-temperature environment. The air volume can be adjusted by a variable frequency fan or an EC (Embedded Controller) fan.
