Description

Technical Field

[0001] The present disclosure relates to the technical field of air conditioners, and in particular, to an air conditioner control method, an air conditioner, a device, a storage medium, and a program product. Background Art

[0002] In the related art, during the operation of an air conditioner, the exhaust temperature of the compressor may be unstable due to harsh environments, which not only affects the service life of the compressor but also the overall reliability of the air conditioner.

[0003] During the operation of an air conditioner, the stability of the exhaust temperature of the compressor directly affects the performance and reliability of the air conditioner. In harsh environments, the exhaust temperature is prone to rapid rises or falls, resulting in unstable operation of the air conditioner and even triggering abnormal shutdowns. In the prior art, the compressor frequency reduction limit is mostly used to control the exhaust temperature, but this method significantly reduces the cooling or heating capacity of the compressor, affecting the user experience. In addition, the response speed of this control method is slow, making it difficult to effectively cope with sudden fluctuations in the exhaust temperature. Especially under high load or extreme working conditions, it is easy to trigger a protection mechanism due to exhaust overshoot, further exacerbating the unstable operation of the air conditioner. Therefore, there is an urgent need for a more efficient and stable control method to improve the operation reliability and energy efficiency performance of the air conditioner.

[0071] Here, some exemplary embodiments of the present disclosure will be described in detail, and examples thereof are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. Various changes, modifications, and equivalents of the methods, apparatuses, and / or systems described herein will become apparent after understanding the present disclosure. For example, the order of operations described herein is merely an example and is not limited to those set forth herein, but may be changed as will be apparent after understanding the present disclosure, except for operations that must be performed in a specific order. Additionally, descriptions of features known in the art may be omitted for the sake of clarity and conciseness.

[0072] The implementation manners described in some of the following exemplary embodiments of the present disclosure do not represent all implementation manners consistent with the present disclosure. Instead, they are merely examples of apparatuses and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0073] In the related art, during the operation of an air conditioner, the exhaust temperature of the compressor may be unstable due to a harsh environment, which not only affects the service life of the compressor but also the overall reliability of the air conditioner. Therefore, there is an urgent need for a new air conditioner control scheme to improve the reliability and stability of the compressor exhaust temperature.

[0074] Next, each step of the method in the exemplary embodiments of the present disclosure will be described in more detail with reference to the drawings and embodiments.

[0075] Figure 1 A flowchart of an air conditioner control method according to an exemplary embodiment of the present disclosure.

[0076] As Figure 1 shown, in some embodiments, the air conditioner control method of the present disclosure example includes:

[0077] In step S102, obtain the exhaust temperature of the above air conditioner.

[0078] In some exemplary embodiments of the present disclosure, the position of the compressor exhaust temperature sensor of a household air conditioner is generally located on the compressor exhaust pipe, and the exhaust temperature is obtained through the temperature sensor.

[0079] In some exemplary embodiments of the present disclosure, industrial air conditioners are usually equipped with dedicated control systems for monitoring and managing the operating status of the air conditioners. For some industrial scenarios with high requirements for temperature monitoring accuracy, professional temperature monitoring devices such as infrared temperature sensors and thermocouple thermometers are additionally installed. The infrared temperature sensor can non-contactedly measure the temperature of the surface of the compressor exhaust pipe and transmit the measurement data to the data acquisition system for processing and display. The thermocouple thermometer measures the temperature by directly contacting the exhaust pipe and utilizes the thermoelectric effect, featuring a fast response speed and high accuracy.

[0080] In step S104, a preset exhaust temperature is determined, where the preset exhaust temperature includes a preset variable-frequency exhaust temperature.

[0081] In some exemplary embodiments of the present disclosure, the preset variable-frequency exhaust temperature includes the exhaust temperature corresponding to slow frequency increase, the exhaust temperature corresponding to frequency limitation, and the exhaust temperature corresponding to triggering frequency reduction, but is not limited thereto.

[0082] In some exemplary embodiments of the present disclosure, slow frequency increase refers to the process in which the compressor frequency gradually increases when the variable-frequency air conditioner starts or the operating conditions are adjusted. The exhaust temperature corresponding to this process is the temperature change of the discharged gas when the compressor frequency slowly increases. For example, when the air conditioner is just turned on, to avoid sudden changes in the compressor load, it starts at a low frequency and slowly increases the frequency. During this period, as the compressor work increases, the exhaust temperature gradually rises, starting from a relatively low temperature (such as the ambient temperature) and climbing at a relatively gentle rate.

[0083] In some exemplary embodiments of the present disclosure, when the exhaust temperature reaches a set value, to prevent it from continuing to rise and causing damage to the compressor, the operating frequency of the compressor is limited, and this set value is the exhaust temperature corresponding to frequency limitation. For compressors of different types and uses, this temperature limit value varies.

[0084] In some exemplary embodiments of the present disclosure, when the exhaust temperature rises above a specific threshold, the compressor must reduce its operating frequency, and this temperature that prompts the compressor to reduce frequency is the exhaust temperature corresponding to triggering frequency reduction. When the air conditioner operates at a high load or there is a refrigerant leak, etc., the exhaust temperature may rise rapidly. Once it reaches the temperature threshold for triggering frequency reduction, the frequency reduction mechanism will be triggered.

[0085] In some exemplary embodiments of the present disclosure, there is a magnitude relationship of the exhaust temperature corresponding to slow frequency increase < the exhaust temperature corresponding to frequency limitation < the exhaust temperature corresponding to triggering frequency reduction, but is not limited thereto.

[0086] In step S106, overshoot protection control of the exhaust temperature of the air conditioner is performed according to the magnitude relationship between the exhaust temperature and the preset variable-frequency exhaust temperature.

[0087] In some exemplary embodiments of the present disclosure, the exhaust temperature of the air conditioner is controlled by the size relationship between the exhaust temperature and the preset variable frequency exhaust temperature, thereby improving the stability and reliability of the exhaust temperature during operation of the air conditioner and reducing the probability of abnormal shutdown caused by exhaust overshoot, compressor failure and other faults.

[0088] In some exemplary embodiments of the present disclosure, the setting of the variable frequency exhaust temperature is to reduce the power consumption of the air conditioner through exhaust temperature control, and reuse the variable frequency exhaust temperature to adjust the opening and closing degree, opening and closing adjustment rate, indoor unit wind speed and outdoor unit wind speed of the electronic expansion valve of the air conditioner during the variable frequency operation process, so as to comprehensively improve the stability and reliability of the air conditioner compressor by keeping the exhaust temperature stable.

[0089] In some exemplary embodiments of the present disclosure, the exhaust temperature control can be refined into two control processes, namely, by refining the judgment conditions of the exhaust temperature, the adjustment method of the opening and closing degree of the electronic expansion valve, the opening and closing adjustment rate, the indoor unit wind speed, and the outdoor unit wind speed can be further refined.

[0090] In some exemplary embodiments of the present disclosure, the preset variable frequency exhaust temperature includes but is not limited to the following:

[0091] T 排气升频温度 ——Exhaust gas temperature corresponding to frequency increase.

[0092] T 排气限频温度 ——Exhaust gas temperature corresponding to frequency limit.

[0093] T 排气降频温度 ——Exhaust gas temperature corresponding to frequency reduction.

[0094] T 排气升频温度 <T 排气限频温度 <T 排气降频温度 .

[0095] Figure 2 The figure is a flowchart of an air conditioning control method according to an exemplary embodiment of the present disclosure.

[0096] like Figure 2 As shown, in Figure 1 Based on the air conditioning control method shown, the above step S106 may include the following steps.

[0097] In step S202, in response to the frequency-limited exhaust temperature being less than or equal to the exhaust temperature, the exhaust temperature of the air conditioner is controlled.

[0098] In some exemplary embodiments of the present disclosure, by controlling the exhaust gas temperature of the air conditioner in response to the limited-frequency exhaust gas temperature being less than or equal to the exhaust gas temperature, the reliability and stability of the compressor exhaust gas temperature are improved by increasing the rate of reducing the exhaust gas temperature.

[0099] In some exemplary embodiments of the present disclosure, the limited-frequency exhaust gas temperature is a temperature determined according to the exhaust gas temperature corresponding to the limited frequency.

[0100] In some exemplary embodiments of the present disclosure, the limited-frequency exhaust gas temperature may be T 排气限频温度 + 1 °C.

[0101] Figure 3 It is a schematic flow chart of an air conditioner control method shown according to an exemplary embodiment of the present disclosure.

[0102] As Figure 3 shown, based on the air conditioner control method shown in Figure 2 the above, the above step S202 may include the following steps.

[0103] In step 302, in response to the completion of the above first exhaust gas temperature overshoot protection control, the exhaust gas temperature is detected again.

[0104] In step S304, in response to the exhaust gas temperature being less than or equal to the above frequency-increasing exhaust gas temperature, the above first exhaust gas temperature overshoot protection control is allowed to be executed again according to the magnitude relationship between the above limited-frequency exhaust gas temperature and the exhaust gas temperature.

[0105] In some exemplary embodiments of the present disclosure, the frequency-increasing exhaust gas temperature is a temperature determined according to the exhaust gas temperature corresponding to a slow frequency increase.

[0106] In some exemplary embodiments of the present disclosure, the frequency-increasing exhaust gas temperature may be T 排气升频温度 .

[0107] In some exemplary embodiments of the present disclosure, by controlling the above first exhaust gas temperature of the air conditioner again in response to the limited-frequency exhaust gas temperature being less than or equal to the exhaust gas temperature, the electronic expansion valve, the indoor unit, the outdoor unit, etc. are more precisely controlled to perform corresponding actions, reducing the probability of mis-triggering the execution of the first exhaust gas temperature control, and while improving the stability of the compressor exhaust gas temperature, the air conditioner energy consumption is also saved.

[0108] Figure 4 It is a schematic flow chart of an air conditioner control method shown according to an exemplary embodiment of the present disclosure.

[0109] As Figure 4 shown, based on the air conditioner control method shown in Figure 2 the above, the above step S202 may include the following steps.

[0111] In some exemplary embodiments of the present disclosure, the opening degree of the electronic expansion valve of the above air conditioner can be increased step by step until the first target opening degree is reached.

[0112] In some exemplary embodiments of the present disclosure, the rate of stepwise adjustment of the opening degree of the electronic expansion valve is to increase by 15P ± 5P every 25 s or 30 s or 35 s.

[0113] In some exemplary embodiments of the present disclosure, the first target opening degree is 60P ± 5P.

[0114] In some exemplary embodiments of the present disclosure, after adjusting the opening degree of the electronic expansion valve until the first target opening degree is reached, continue to adjust the opening degree of the electronic expansion valve according to the preset proportional relationship between the exhaust temperature and the opening degree of the electronic expansion valve.

[0115] In step S404, in response to the above air conditioner being in the cooling operation state, increase the wind speed of the outdoor unit of the above air conditioner.

[0116] In some exemplary embodiments of the present disclosure, in the cooling operation state, the rotation speed of the outdoor unit increases by 10% or 15% or 20%.

[0121] In step S502, in response to the above frequency-down exhaust temperature being less than or equal to the above exhaust temperature, perform the above second exhaust temperature overshoot protection control on the above air conditioner.

[0122] In some exemplary embodiments of the present disclosure, the frequency-down exhaust temperature is higher than the frequency-limiting exhaust temperature and the frequency-up exhaust temperature.

[0123] In some exemplary embodiments of the present disclosure, the frequency-down exhaust temperature is determined according to the exhaust temperature corresponding to the triggered frequency-down.

[0129] In some exemplary embodiments of the present disclosure, by responding to the above frequency-down exhaust temperature being less than or equal to the above exhaust temperature, the air conditioner is controlled again for the above second exhaust temperature control, more precisely controlling the electronic expansion valve, the indoor unit, the outdoor unit, etc. to perform corresponding actions, reducing the probability of mis-triggering the execution of the second exhaust temperature control, improving the stability of the compressor exhaust temperature while also saving air conditioner energy consumption.

[0162] As Figure 12 shown, on the basis of the air conditioner control method shown in Figure 1 - 8 the air conditioner control method may further include the following steps.

[0163] In step S1202, according to the change trend of the above-mentioned exhaust temperature and the magnitude relationship between the above-mentioned exhaust temperature and the above-mentioned target exhaust temperature, the opening degree of the electronic expansion valve of the above-mentioned air conditioner is adjusted.

[0164] Figure 13 It is a schematic flow chart of an air conditioner control method shown according to an exemplary embodiment of the present disclosure.

[0165] As Figure 13 shown, on the basis of the air conditioner control method shown in Figure 12 =]]step S1202 may include the following steps.

[0166] In step S1302, in response to the above-mentioned exhaust temperature being in a rising state and for the first time in response to the above-mentioned exhaust temperature belonging to the first temperature range, the reduction of the opening degree of the electronic expansion valve of the above-mentioned air conditioner is restricted, and the first temperature range is determined by the target exhaust temperature of the above-mentioned air conditioner.

[0167] In some exemplary embodiments of the present disclosure, the first temperature range is (T d_target -15 °C, T d_target -5 °C), and T d_target is a temperature value determined according to the target exhaust temperature.

[0168] In some exemplary embodiments of the present disclosure, in response to the above-mentioned exhaust temperature being in a rising state and for the first time in response to the above-mentioned exhaust temperature belonging to the first temperature range, the reduction of the opening degree of the electronic expansion valve of the above-mentioned air conditioner is restricted and maintained for 3 - 7 minutes.

[0169] Figure 14 It is a schematic flow chart of an air conditioner control method shown according to an exemplary embodiment of the present disclosure.

[0170] As Figure 14 shown, on the basis of Figure 12Based on the air conditioner control method shown above, step S1202 may include the following steps.

[0171] In step S1402, in response to the exhaust temperature being in a decreasing state and for the first time in response to the exhaust temperature belonging to a second temperature range, restrict the opening degree of the electronic expansion valve of the air conditioner from decreasing. The second temperature range is determined by the target exhaust temperature of the air conditioner.

[0172] In some exemplary embodiments of the present disclosure, the first temperature range is (T d_target +4°C, T d_target +6°C), where T d_target is a temperature value determined according to the target exhaust temperature.

[0173] In some exemplary embodiments of the present disclosure, in response to the exhaust temperature being in a decreasing state and for the first time in response to the exhaust temperature belonging to a second temperature range, restrict the opening degree of the electronic expansion valve of the air conditioner from decreasing and maintain it for 3 - 7 minutes.

[0174] Figure 15 is a schematic flowchart of an air conditioner control method shown according to an exemplary embodiment of the present disclosure.

[0175] As Figure 15 shown, based on the air conditioner control method shown above, step S1202 may include the following steps. Figure 12

[0176] In step S1502, in response to the compressor of the air conditioner being in a positive overshoot state, and in response to the exhaust temperature belonging to a third temperature range, and based on the change in the exhaust temperature to determine that the exhaust temperature is in a decreasing stage, restrict the opening degree of the electronic expansion valve of the air conditioner from decreasing. The third temperature range is determined by the target exhaust temperature of the air conditioner.

[0177] In some exemplary embodiments of the present disclosure, the third temperature range is (T d_target +3°C, +∞).

[0178] In some exemplary embodiments of the present disclosure, positive overshoot means that when the air conditioner is cooling or heating, the indoor temperature adjustment exceeds the set temperature target value. For example, in the cooling mode, if the set temperature is 26°C, but the air conditioner continuously cools until the indoor temperature drops to 24°C, which is 2°C lower than the set temperature, this is positive overshoot.

[0179] ​In some exemplary embodiments of the present disclosure, the generation of positive overshoot may be due to certain errors in the temperature sensor of the air conditioner, inaccurate temperature information fed back to the control system, resulting in the control system continuing to cool, or the cooling power of the air conditioner being too large. When the indoor temperature approaches the set temperature, it is unable to stop cooling in time, thus causing the temperature to drop excessively.

[0180] Figure 16 It is a schematic flow chart of an air conditioner control method shown according to an exemplary embodiment of the present disclosure.

[0181] As Figure 16 shown, based on the air conditioner control method shown in Figure 12 shown, step S1202 may include the following steps.

[0182] In step S1602, in response to the compressor of the air conditioner being in a negative overshoot state, and in response to the exhaust temperature belonging to the fourth temperature range, and determining that the exhaust temperature is in a heating stage according to the change of the exhaust temperature, restrict the opening degree of the electronic expansion valve of the air conditioner from decreasing. The fourth temperature range is determined by the target exhaust temperature of the air conditioner.

[0183] In some exemplary embodiments of the present disclosure, negative overshoot means that the indoor temperature after the air conditioner adjusts does not reach the set temperature target value. For example, taking the heating mode as an example, the set temperature is 22°C, but the indoor temperature only rises to 20°C after the air conditioner runs and fails to reach the set 22°C. This situation is negative overshoot.

[0184] In some exemplary embodiments of the present disclosure, the occurrence of negative overshoot may be due to insufficient heating capacity of the air conditioner. For example, the air conditioner capacity does not match the room area. The room area is too large while the air conditioner capacity is too small, resulting in the inability to effectively increase the indoor temperature, or there is a fault in the heating system of the air conditioner, such as refrigerant leakage, heating element damage, etc., affecting the heating effect.

[0185] In some exemplary embodiments of the present disclosure, the fourth temperature range is (-∞, T d_target + 3°C).
