Description

Technical Field

[0001] This invention relates to the field of air conditioning comfort control technology, and more specifically, to a control method, device, and air conditioner for improving the heating cycle of an air conditioner. Background Technology

[0002] Currently, when most air conditioners are running continuously in heating mode, the temperature of the outdoor unit's condenser will decrease over time, leading to frost buildup on the condenser. This results in frequent defrosting, a poor user experience, and also hinders the air conditioner's heat exchange efficiency. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a control method for improving the heating cycle of an air conditioner. The method includes: when the air conditioner is in heating operation, detecting whether the exhaust temperature is less than or equal to an exhaust temperature threshold; if the exhaust temperature is less than or equal to the exhaust temperature threshold, detecting whether the external circuit temperature is less than or equal to zero; if the external circuit temperature is less than or equal to zero, detecting whether the difference between the current value of the external circuit temperature and a historical value before a preset time period is greater than a difference threshold; if it is greater than the difference threshold, adjusting the speed of the outdoor unit according to the internal circuit temperature; the speed of the outdoor unit is negatively correlated with the internal circuit temperature.

[0004] In this embodiment of the invention, the outdoor unit speed can be adjusted in real time based on the exhaust temperature, outer plate temperature, and inner plate temperature. The outdoor unit speed is only adjusted when the above parameters meet the conditions, thereby reducing heat exchanger frost formation, extending the heating cycle, avoiding repeated defrosting, and improving room comfort.

[0005] Optionally, adjusting the outdoor unit's speed based on the inner chassis temperature includes: if the inner chassis temperature is greater than or equal to a high-temperature threshold, controlling the outdoor unit to continue operating at the current speed; if the inner chassis temperature is less than the high-temperature threshold but greater than or equal to a low-temperature threshold, calculating the outdoor unit's speed based on the following formula, and controlling the outdoor unit to operate at the calculated speed:

[0006]

[0007] Where M is the outdoor unit's rotational speed, B is the indoor unit's high temperature threshold, A is the outdoor unit's current rotational speed, N is the outdoor unit's maximum rotational speed, and T is the outdoor unit's maximum rotational speed. 内盘 The temperature of the inner disk is the inner disk temperature; if the inner disk temperature is less than the inner disk low temperature threshold, the outdoor unit is controlled to run at the maximum speed.

[0008] In this embodiment of the invention, the temperature of the inner plate is used as the basis for adjusting the speed of the outdoor unit, which can achieve precise control of the speed, improve the heat exchange effect, and reduce the frost formation on the heat exchanger.

[0009] Optionally, the method further includes: if the exhaust temperature is greater than the exhaust temperature threshold, then controlling the outdoor unit to continue running at the current speed.

[0010] In this embodiment of the invention, when the exhaust temperature is greater than the exhaust temperature threshold, there is no need to increase the outdoor unit speed, thereby reducing heat exchanger frost formation and extending the heating cycle.

[0011] Optionally, the method further includes: if the temperature of the outer disk is greater than zero, controlling the outdoor unit to continue running at the current speed.

[0012] In this embodiment of the invention, when the external plate temperature is greater than zero, there is no need to increase the outdoor unit speed, thereby reducing heat exchanger frost formation and extending the heating cycle.

[0013] Optionally, before detecting whether the exhaust temperature is less than or equal to the exhaust temperature threshold, the method further includes: detecting whether the rotation speed of the outdoor unit is less than the maximum rotation speed; if it is less than the maximum rotation speed, then continuing to execute the step of detecting whether the exhaust temperature is less than or equal to the exhaust temperature threshold; if it is equal to the maximum rotation speed, then controlling the outdoor unit to continue running at the current rotation speed.

[0014] In this embodiment of the invention, it can first determine whether the outdoor unit speed has reached the maximum speed. If the maximum speed has been reached, there is no need to execute the subsequent judgment and speed adjustment loop algorithm.

[0015] Optionally, the high temperature threshold of the inner disk is in the range of 55-65; the low temperature threshold of the inner disk is in the range of 45-50.

[0016] Optionally, the exhaust temperature threshold value ranges from 50 to 115; and / or, the difference threshold value ranges from 0 to 20.

[0017] The embodiments of the present invention provide the value range of each parameter, which can confirm the accuracy of temperature changes and achieve precise control of rotation speed.

[0025] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0026] In this embodiment of the invention, when the external DC motor air conditioner is in heating mode, it can control the speed of the external motor by combining the changes in exhaust and inner and outer coil temperatures. Under the premise of ensuring motor reliability, it can improve the heat exchange effect, reduce heat exchanger frost formation, extend the heating cycle, improve comfort, and enhance the user experience.

[0027] Figure 1 A schematic flowchart of a control method for improving the heating cycle of an air conditioner according to an embodiment of the present invention is shown. The method includes the following steps:

[0028] S102, when the air conditioner is in heating mode, detect whether the exhaust temperature is less than or equal to the exhaust temperature threshold.

[0029] When the air conditioner is in heating mode, it detects the current exhaust temperature. If the exhaust temperature is less than or equal to the preset exhaust temperature threshold, it indicates that there is room for further improvement in heating capacity. The system continues with subsequent judgment steps to ultimately determine whether to increase the outdoor unit's speed. If the exhaust temperature is greater than the exhaust temperature threshold, it indicates that the exhaust temperature is suitable and no change is needed; the outdoor unit continues to operate at the current speed.

[0030] S104, if the exhaust temperature is less than or equal to the exhaust temperature threshold, then check whether the outer disk temperature is less than or equal to zero.

[0031] When the external condenser temperature is above zero, the condenser will not frost, and the outdoor unit can continue to run at the current speed. When the external condenser temperature is less than or equal to zero, the condenser may frost, and the outdoor unit's speed should be adjusted based on the rate of decrease in external condenser temperature and the internal condenser temperature.

[0032] S106, If the outer plate temperature is less than or equal to zero, then detect whether the difference between the current value of the outer plate temperature and the historical value before the preset time period is greater than the difference threshold.

[0033] The difference between the current external circuit temperature and the historical value before a preset time interval can be obtained. This difference represents the rate at which the external circuit temperature decreases. If the difference is greater than a threshold, the internal circuit temperature determination step continues. If the difference is less than or equal to the threshold, the outdoor unit is controlled to continue running at the current speed.

[0034] S108, if the difference is greater than the above threshold, the speed of the outdoor unit will be adjusted according to the temperature of the inner plate.

[0035] The outdoor unit's rotational speed is negatively correlated with the indoor unit's temperature. A higher indoor unit temperature requires less increase in outdoor unit speed, while a higher indoor unit temperature requires more increase in outdoor unit speed, up to the maximum speed. Based on this indoor unit temperature control, the outdoor unit's speed is prioritized to delay frosting while maximizing heating capacity. During the air conditioner's heating operation, the above steps can be repeated cyclically to periodically assess the indoor and outdoor unit temperatures, exhaust temperatures, and adjust the outdoor unit's rotational speed accordingly.

[0036] Optionally, the outdoor unit's speed can be adjusted according to the inner panel temperature, as follows:

[0037] (1) If the inner plate temperature is greater than or equal to the inner plate high temperature threshold, the outdoor unit will continue to run at the current speed.

[0038] (2) If the inner plate temperature is less than the inner plate high temperature threshold and greater than or equal to the inner plate low temperature threshold, the outdoor unit speed is calculated based on the following formula, and the outdoor unit is controlled to run at the calculated outdoor unit speed:

[0039]

[0040] Where M is the outdoor unit's rotational speed, B is the aforementioned internal chassis high-temperature threshold, A is the outdoor unit's current rotational speed, N is the outdoor unit's maximum rotational speed, and T... 内盘 This represents the inner plate temperature. Optionally, M can be an integer.

[0041] As shown in the formula above, T 内盘 The larger the value of T, the smaller the calculated rotational speed M value, while T... 内盘 The smaller the value, the larger the calculated rotational speed M value.

[0042] (3) If the inner plate temperature is less than the inner plate low temperature threshold, the outdoor unit will be controlled to run at the maximum speed.

[0043] The air conditioner heating cycle improvement control method provided in this embodiment of the invention can adjust the outdoor unit speed in real time based on the exhaust temperature, outdoor unit temperature and indoor unit temperature. The outdoor unit speed is only adjusted when the above parameters meet the conditions, thereby reducing heat exchanger frost, extending the heating cycle, avoiding repeated defrosting, and improving room comfort.

[0044] Considering that the outdoor unit may already be running at maximum speed, before checking whether the exhaust temperature is less than or equal to the exhaust temperature threshold, the above method may also include:

[0045] First, it checks if the outdoor unit's rotational speed is less than the maximum rotational speed. Then, if it is less than the maximum rotational speed, it continues to execute the step of checking if the exhaust temperature is less than or equal to the exhaust temperature threshold. If it is equal to the maximum rotational speed, it controls the outdoor unit to continue running at the current rotational speed. In this embodiment, it can first determine whether the outdoor unit's rotational speed has reached the maximum rotational speed. If it has reached the maximum rotational speed, there is no need to execute the subsequent judgment and speed adjustment loop algorithm.

[0046] For example, the range of the high temperature threshold of the inner plate is 55-65; the range of the low temperature threshold of the inner plate is 45-50.

[0047] For example, the exhaust temperature threshold value ranges from 50 to 115; and / or, the difference threshold value ranges from 0 to 20.

[0048] Figure 2 A schematic flowchart of a control method for improving the heating cycle of an air conditioner according to an embodiment of the present invention is shown. The method includes:

[0049] S201, Air conditioning is in heating mode.

[0050] After the air conditioner stabilizes, the outdoor motor speed is adjusted according to the defined categories of exhaust, inner panel, and outer panel temperatures. In this embodiment, the values ​​for each parameter are primarily based on existing air conditioner operating scenarios and are commonly used values ​​for current air conditioners. Specifically:

[0051] A represents the operating speed of the air conditioner's external motor, ranging from 0 to 1100. In this embodiment, the value is 900, which is taken as the normal operating speed of a DC motor.

[0052] B represents the high temperature threshold of the inner plate, ranging from 0 to 65, and is set to 55 in this embodiment; the air conditioner performs better at temperatures above this level under normal operating conditions.

[0053] C represents the low temperature threshold of the inner disk, ranging from 0 to 50, and is set to 45 in this embodiment.

[0054] N represents the maximum speed of the external motor, ranging from 500 to 1800 RPM. In this embodiment, the value is 1100 RPM. The maximum speed under reliable motor conditions can generally be found in the external motor's specifications.

[0055] M is the adjusted external motor speed;

[0056] 'a' represents the exhaust temperature threshold, ranging from 50 to 115°C; in this embodiment, the value is 75.

[0057] b is the difference threshold, ranging from 0 to 20, and is set to 5 in this embodiment;

[0058] The remaining parameters were selected based on current air conditioner technology and empirical values.

[0059] S202, records the current outdoor unit speed A and T. 内环 .

[0060] S203, determine whether A < N. If yes, execute S204; otherwise, execute S217.

[0061] S204, Detecting exhaust temperature T 排 .

[0062] S205, determine whether T is satisfied. 排 ≥a. If yes, then execute S206; otherwise, execute S207.

[0063] S206 has a suitable exhaust temperature, requires no changes, and operates stably.

[0064] S207, T detection 外盘 .

[0065] S208, determine whether T is satisfied. 外盘 >0℃. If yes, proceed to S209; otherwise, proceed to S210.

[0066] S209: The condenser is not frosted and is operating stably. If the external circuit temperature is above 0℃, the condenser is not frosted and is operating stably.

[0067] S210, determine whether T is satisfied. 0s-前20s >b. If yes, then execute S211-S213; otherwise, execute S209.

[0068] Determine the current T 外盘0s T 20 seconds ago 外盘前20s Is the difference greater than the threshold?

[0069] S211, determine whether T is satisfied.内盘 ≥B. If so, then execute S214.

[0070] S212, determine whether B≥T is satisfied. 内盘 ≥C. If so, then execute S215.

[0071] S213, determine whether T is satisfied. 内盘 <C. If yes, then execute S216.

[0072] S214, with reasonable internal plate temperature and stable operation.

[0073] S215, the inner chassis temperature is slightly low, increase the external motor speed to...

[0074] S216, with low inner plate temperature, increase the external motor speed to the maximum N.

[0075] S217 is operating stably.

[0076] The internal coil temperature of the air conditioner is used as a reference and basis for determining the compressor frequency. Combined with changes in the internal coil temperature, precise parameter adjustment is achieved. The above steps can be repeated cyclically.

[0077] For example, heating condition 1 is as follows:

[0078] Outdoor unit speed 900, exhaust T 0s =70, exhaust T 外盘 =-5,T 0s-前20s = -11℃, T 内盘 =45℃;

[0079] Therefore, the unit adjusts the indoor unit speed M = (1100-900)(55-45) / 55+900 = 936.

[0080] For example, heating condition 2 is as follows:

[0081] Outdoor unit speed 900, exhaust T 0s =70, exhaust T 外盘 =-5,T 0s-前20s = -11℃, T 内盘 =40℃;

[0082] Then, the unit adjusts the indoor unit speed M = 1100.

[0083] In this embodiment, through a periodic loop algorithm of the inner and outer discs and exhaust, the external motor speed can be adjusted in real time during heating operation to extend the heating cycle, avoid repeated defrosting, and improve room comfort. In medium and low temperature environments, the speed can be adjusted according to the actual scenario to improve heat exchange effect, reduce frost formation on the heat exchanger, achieve the optimal heating effect of the air conditioner, and enhance the user experience. By setting the range of differences in the inner and outer discs and exhaust, the accuracy of temperature change can be confirmed, and precise control of the speed can be achieved.
