[0002] In related technologies, during the operation of an air conditioner, the exhaust temperature of the compressor may become 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 air conditioner operation, the stability of the compressor's exhaust temperature directly affects the air conditioner's performance and reliability. In harsh environments, the exhaust temperature is prone to rapid rises or falls, leading to unstable operation and even triggering abnormal shutdowns. Current technologies often use compressor frequency limiting to control exhaust temperature, but this method significantly reduces the compressor's cooling or heating capacity, impacting user experience. Furthermore, this control method has a slow response time and struggles to effectively handle sudden fluctuations in exhaust temperature, especially under high loads or extreme conditions. It is prone to triggering protection mechanisms due to exhaust overshoot, further exacerbating the air conditioner's operational instability.

[0045] Exemplary embodiments of this disclosure will be described in detail herein, examples of which are illustrated in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings denote the same or similar elements unless otherwise indicated. Various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will become apparent upon understanding this disclosure. For example, the order of operations described herein is merely illustrative and is not limited to those orders set forth herein, but can be changed as will become apparent upon understanding this disclosure, except for operations that must be performed in a particular order. Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

[0046] The embodiments described below, which are examples of some of the embodiments of this disclosure, do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0047] In related technologies, during air conditioner operation, harsh environments can cause unstable compressor discharge temperatures, affecting not only the compressor's lifespan but also the overall reliability of the air conditioner. Therefore, a new air conditioning control scheme is urgently needed to improve the reliability and stability of compressor discharge temperatures.

[0048] The steps of the method in the exemplary embodiments of this disclosure will now be described in more detail with reference to the accompanying drawings and examples.

[0049] Figure 1 This is a flowchart illustrating an air conditioning control method according to an exemplary embodiment of the present disclosure.

[0050] like Figure 1 As shown, in some embodiments, the air conditioning control method of this disclosure includes: In step S102, the exhaust temperature of the air conditioner is obtained.

[0051] In some exemplary embodiments of this disclosure, 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.

[0052] In some exemplary embodiments of this disclosure, industrial air conditioners are typically equipped with a dedicated control system for monitoring and managing their operating status. For industrial scenarios requiring high temperature monitoring accuracy, additional specialized temperature monitoring equipment, such as infrared temperature sensors and thermocouple thermometers, is installed. Infrared temperature sensors can non-contactly measure the temperature of the compressor exhaust pipe surface, transmitting the measurement data to a data acquisition system for processing and display. Thermocouple thermometers measure temperature through direct contact with the exhaust pipe, utilizing the thermoelectric effect, and are characterized by fast response and high accuracy.

[0053] In step S104, a preset exhaust temperature is determined, wherein the preset exhaust temperature includes a preset frequency converter exhaust temperature.

[0054] In some exemplary embodiments of this disclosure, the preset frequency conversion exhaust temperature includes, but is not limited to, the exhaust temperature corresponding to slow frequency increase, the exhaust temperature corresponding to frequency limit, and the exhaust temperature corresponding to trigger frequency reduction.

[0055] In some exemplary embodiments of this disclosure, slow frequency increase refers to the process of gradually increasing the compressor frequency when the inverter air conditioner starts or adjusts its operating conditions. The corresponding exhaust temperature is the temperature change of the discharged gas as the compressor frequency slowly increases. For example, when the air conditioner is first turned on, to avoid sudden changes in compressor load, it will start at a low frequency and slowly increase the frequency. During this period, as the compressor's work increases, the exhaust temperature will gradually rise, starting from a lower temperature (such as ambient temperature) and climbing at a relatively gentle rate.

[0056] In some exemplary embodiments of this disclosure, when the exhaust temperature reaches a set value, the compressor's operating frequency is limited to prevent it from continuing to rise and damaging the compressor. This set value is the exhaust temperature corresponding to the limited frequency. This temperature limit varies for different types and applications of compressors.

[0057] In some exemplary embodiments of this disclosure, when the exhaust temperature rises above a specific threshold, the compressor must reduce its operating frequency. This temperature that causes the compressor to reduce its frequency is the exhaust temperature that triggers the frequency reduction. When the air conditioner is operating under high load or when refrigerant leakage occurs, the exhaust temperature may rise rapidly. Once it reaches the temperature threshold that triggers the frequency reduction, the frequency reduction mechanism will be activated.

[0058] In some exemplary embodiments of this disclosure, there exists a relationship where the exhaust temperature corresponding to slow frequency increase is less than the exhaust temperature corresponding to the limiting frequency, which is less than the exhaust temperature corresponding to trigger frequency decrease, but this is not the only one.

[0059] In step S106, exhaust temperature overshoot protection control is performed on the air conditioner based on the relationship between the exhaust temperature and the preset variable frequency exhaust temperature.

[0060] In some exemplary embodiments of this disclosure, the exhaust temperature of the air conditioner is controlled by the relationship between the exhaust temperature and the preset variable frequency exhaust temperature, which improves the stability and reliability of the exhaust temperature during operation and reduces the probability of abnormal shutdown, compressor failure and other malfunctions caused by exhaust overshoot.

[0061] In some exemplary embodiments of this disclosure, the variable frequency exhaust temperature setting is used to reduce the power consumption of the air conditioner by controlling the exhaust temperature, while reusing the variable frequency exhaust temperature to adjust the opening and closing degree, opening and closing degree adjustment rate, indoor unit fan speed, and outdoor unit fan speed of the air conditioner during variable frequency operation, so as to comprehensively improve the stability and reliability of the air conditioner compressor while maintaining a stable exhaust temperature.

[0062] In some exemplary embodiments of this disclosure, exhaust temperature control can be refined into two control processes: by refining the judgment conditions for exhaust temperature, the adjustment methods for the opening and closing degree of the electronic expansion valve, the opening and closing degree adjustment rate, the indoor unit fan speed, and the outdoor unit fan speed can be further refined.

[0063] In some exemplary embodiments of this disclosure, the preset variable frequency exhaust temperature includes, but is not limited to, the following: T 排气升频温度 —The exhaust temperature corresponding to the frequency increase.

[0064] T 排气限频温度 —Exhaust temperature corresponding to frequency limiting.

[0065] T 排气降频温度 —The exhaust temperature corresponding to frequency reduction.

[0066] T 排气升频温度 <T 排气限频温度 <T 排气降频温度 .

[0100] In step S604, in response to the exhaust temperature being less than or equal to the frequency-increasing exhaust temperature, the second exhaust temperature overshoot protection control is allowed to be executed again based on the relationship between the frequency-reducing exhaust temperature and the exhaust temperature.

[0140] In some exemplary embodiments of this disclosure, in response to the exhaust temperature being in a rising state, and in response for the first time that the exhaust temperature is within a first temperature range, the opening degree of the electronic expansion valve of the air conditioner is limited to decrease and maintained for 3-7 minutes.

[0141] Figure 14 This is a flowchart illustrating an air conditioning control method according to an exemplary embodiment of the present disclosure.

[0142] like Figure 14 As shown, in Figure 12Based on the air conditioning control method shown, step S1202 may include the following steps.

[0143] In step S1402, in response to the exhaust temperature being in a cooling state and in response to the exhaust temperature being in the second temperature range for the first time, the opening degree of the electronic expansion valve of the air conditioner is limited to decrease, and the second temperature range is determined by the target exhaust temperature of the air conditioner.

[0144] In some exemplary embodiments of this disclosure, the first temperature range is ( +4℃ +6℃ This is the temperature value determined based on the target exhaust temperature.

[0145] In some exemplary embodiments of this disclosure, in response to the exhaust temperature being in a cooling state, and for the first time in response to the exhaust temperature being in a second temperature range, the opening degree of the electronic expansion valve of the air conditioner is limited to decrease and maintained for 3-7 minutes.

[0146] Figure 15 This is a flowchart illustrating an air conditioning control method according to an exemplary embodiment of the present disclosure.

[0147] like Figure 15 As shown, in Figure 12 Based on the air conditioning control method shown, step S1202 may include the following steps.

[0148] In step S1502, in response to the compressor of the air conditioner being in a positive over-adjustment state, and in response to the exhaust temperature being in the third temperature range, and in response to the change in the exhaust temperature being determined to be in the cooling stage, the opening degree of the electronic expansion valve of the air conditioner is restricted from decreasing. The third temperature range is determined by the target exhaust temperature of the air conditioner.

[0149] In some exemplary embodiments of this disclosure, the third temperature range is ( +3℃, +∞).

[0150] In some exemplary embodiments of this disclosure, positive over-adjustment refers to the indoor temperature being adjusted beyond the set temperature target value when the air conditioner is cooling or heating. For example, in cooling mode, if the set temperature is 26°C, but the air conditioner continues to cool, causing the indoor temperature to drop to 24°C, which is 2°C lower than the set temperature, this is positive over-adjustment.

[0151] In some exemplary embodiments of this disclosure, positive overshoot may occur due to a certain error in the temperature sensor of the air conditioner, resulting in inaccurate temperature information fed back to the control system, causing the control system to continue cooling, or the cooling power of the air conditioner being too high, making it unable to stop cooling in time when the indoor temperature approaches the set temperature, thus causing the temperature to drop excessively.

[0152] Figure 16 This is a flowchart illustrating an air conditioning control method according to an exemplary embodiment of the present disclosure.

[0153] like Figure 16 As shown, in Figure 12 Based on the air conditioning control method shown, step S1202 may include the following steps.

[0154] In step S1602, in response to the compressor of the air conditioner being in a negative over-adjustment state, and in response to the exhaust temperature being in the fourth temperature range, and in response to the change in the exhaust temperature being determined to be in the heating stage, the opening degree of the electronic expansion valve of the air conditioner is restricted from decreasing. The fourth temperature range is determined by the target exhaust temperature of the air conditioner.

[0155] In some exemplary embodiments of this disclosure, negative over-adjustment means that the indoor temperature after the air conditioner is adjusted does not reach the set temperature target value. For example, taking the heating mode as an example, the set temperature is 22°C, but after the air conditioner is running, the indoor temperature only rises to 20°C and fails to reach the set 22°C. This situation is negative over-adjustment.

[0156] In some exemplary embodiments of this disclosure, negative overheating may occur due to insufficient heating capacity of the air conditioner, such as mismatch between the air conditioner's horsepower and the room area, the room area being too large and the air conditioner's horsepower being too small, resulting in the inability to effectively raise the indoor temperature, or a malfunction in the air conditioner's heating system, such as refrigerant leakage or damage to the heating element, which affects the heating effect.

[0157] In some exemplary embodiments of this disclosure, the fourth temperature range is (-∞, +3℃).
