Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and more specifically, to an air conditioner and its control method, control device, and readable storage medium. Background Technology

[0002] With the increasing national demand for energy storage, the energy storage air conditioning market is booming. Because energy storage integrated cabinets require high reliability from liquid-cooled air conditioners, current bidding requirements for liquid-cooled air conditioners in energy storage systems are for dual-system air conditioners, consisting of dual fans, dual condensers, and dual compressors, providing two cooling systems. However, in actual construction, a problem arises: if the condenser malfunctions, its temperature rises, leading to a significant pressure difference between the two cooling systems. On the side with higher pressure, the air conditioner components operate under high load, which, after prolonged operation, can easily cause damage, increasing repair frequency and costs, and significantly impacting the user experience. Summary of the Invention

[0003] Therefore, the present invention provides an air conditioner and its control method, control device and readable storage medium.

[0004] To address the aforementioned problems, this invention provides a control method for an air conditioner. The air conditioner includes an air duct, a fan unit, and a condenser unit. The fan unit includes a first fan and a second fan. The condenser unit includes a first condenser and a second condenser. A movable partition is provided within the air duct. The partition opens and closes by moving, and the partition is used to divide the air duct into a first air duct corresponding to the first fan and a second air duct corresponding to the second fan. The control method includes: determining the operating status of the first fan and the second fan; acquiring the operating parameters of the first condenser and the second condenser while the first fan and the second fan are operating normally; and controlling the opening and closing of the partition according to the operating parameters of the first condenser and the second condenser, so that the partition separates or merges the first air duct and the second air duct.

[0005] Compared with existing technologies, the technical effects achieved by this solution are as follows: The air conditioner is a dual-system air conditioner with two refrigeration systems. After the air conditioner is turned on, the first and second fans are tested. With both fans running normally, the first and second condensers are also tested. Based on the operating parameters of the first and second condensers, the opening and closing of the baffle is controlled. When the baffle is open, the first and second air ducts merge; when the baffle is closed, they separate. Controlling the baffle opening and closing based on the operating parameters of the first and second condensers makes the control method more reliable and prevents erroneous control of the baffle. When the baffle is open, the first and second air ducts merge, ensuring pressure balance in the two refrigeration systems and preventing damage to the compressor in the higher-pressure system from prolonged high-load operation.

[0006] Furthermore, after determining the operating status of the first fan and the second fan, the control method also includes: if the first fan or the second fan cannot operate, controlling the air conditioner to alarm and controlling the partition to open, so that the partition merges the first air duct and the second air duct.

[0007] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: When one of the fans between the first and second fans fails to operate, the air conditioner needs to output an alarm to remind the user to carry out maintenance. At this time, the partition is opened, the first air duct and the second air duct are merged, so that the operating fan cools the first condenser and the second condenser, balances the pressure of the two refrigeration systems, and prevents the pressure difference of the refrigeration systems from being too large.

[0008] Furthermore, the operating parameters of the first condenser and the second condenser are obtained, specifically including: controlling the operation of the first condenser and the second condenser for a first time, and obtaining the absolute value |ΔP| of the difference between the high pressure P1 of the first condenser and the second high pressure P2 of the second condenser as the operating parameter.

[0009] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: After controlling the operation of the first condenser and the second condenser for a first period of time, the first high pressure P1 of the first condenser and the second high pressure P2 of the second condenser are detected, and the absolute value of the difference between the first high pressure P1 and the second high pressure P2, |ΔP|, is obtained, which makes the judgment of the first condenser and the second condenser more accurate and improves the reliability of the control method.

[0010] Furthermore, based on the operating parameters of the first and second condensers, the opening and closing of the baffle is controlled, specifically including: comparing the absolute value of the difference |ΔP| with the difference threshold P. 阈 The comparison is used to control the opening and closing of the partition.

[0011] Compared with existing technologies, the technical effect achieved by this technical solution is as follows: by comparing the absolute value of the difference |ΔP| with the difference threshold P 阈 By comparing and obtaining the comparison results, the reliability of the control method is improved, thereby controlling the opening and closing of the partition.

[0012] Furthermore, based on the comparison results, the opening and closing of the partition is controlled, specifically including: when the absolute value of the difference |ΔP| is greater than or equal to the difference threshold P. 阈 In this case, the control baffle opens and the condenser group alarm is activated; when the absolute value of the difference |ΔP| is less than the difference threshold P 阈 In this case, the control panel closes.

[0013] Compared with existing technologies, the technical effect achieved by this technical solution is as follows: by comparing the absolute value of the difference |ΔP| with the difference threshold P 阈 The comparison is conducted, and the result is obtained when the absolute value of the difference |ΔP| is greater than or equal to the difference threshold P. 阈 In cases where the high-pressure difference between the first and second condensers is large, indicating a possible blockage in one of the condensers, the condenser assembly will issue an alarm, the baffle will open to accelerate heat dissipation, and the pressure difference between the two refrigeration systems will be prevented from becoming too large. This occurs when the absolute value of the pressure difference, |ΔP|, is less than the pressure difference threshold P. 阈 Under these conditions, the condenser is not clogged, so the air conditioner can operate normally. With the partition closed, the first fan delivers air through the first air duct, and the second fan delivers air through the second air duct.

[0014] Furthermore, controlling the partition to close specifically includes: controlling the partition to close when it is open; and / or controlling the partition to remain closed when it is closed.

[0015] Compared with existing technologies, the technical effect achieved by adopting this technical solution is: timely closure of the partition to prevent mutual interference when the first and second fans are running simultaneously.

[0016] Furthermore, the air conditioner also includes an outdoor unit. After the condenser unit alarms, the control method also includes: determining whether the outdoor unit is running; if the outdoor unit is running, controlling the partition to open; if the outdoor unit is off, controlling the partition to close.

[0017] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: when the outdoor unit is running, the partition opens to accelerate the heat dissipation of the condenser; when the outdoor unit stops running, the partition closes to facilitate the execution of control methods when the air conditioner is turned on again.

[0018] Furthermore, the present invention also provides a control device for controlling an air conditioner. The air conditioner includes an air duct, a fan unit, and a condenser unit. A movable partition is provided inside the air duct. The partition is opened and closed by moving. The partition is used to divide the air duct into a first air duct corresponding to a first fan and a second air duct corresponding to a second fan. The control device includes: a judgment module for judging the operating status of the first fan and the second fan; an acquisition module for acquiring the operating parameters of the first condenser and the second condenser; and a control module for controlling the opening and closing of the partition.

[0019] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: The control device provided by the present invention implements a control method, wherein the judgment module judges the operating status of the first fan and the second fan, the acquisition module acquires the operating parameters of the first condenser and the second condenser, thereby judging whether the first condenser and the second condenser have faults, and the control module controls the opening and closing of the baffle, so that the baffle can merge or separate the first air duct and the second air duct.

[0020] Furthermore, the present invention also provides an air conditioner and an air conditioner execution control method. The air conditioner includes: a fan unit, which includes a first fan and a second fan; an air duct, in which a movable partition is provided. The partition is opened and closed by moving, and the partition is used to divide the air duct into a first air duct corresponding to the first fan and a second air duct corresponding to the second fan.

[0021] Compared with the prior art, the technical effect achieved by adopting this technical solution is that the air conditioner of the present invention implements the control method of the air conditioner of any technical solution of the present invention, and therefore has all the beneficial effects of the control method of the air conditioner of any technical solution of the present invention, which will not be repeated here.

[0022] Furthermore, the present invention also provides a readable storage medium, which includes a stored computer program, wherein the computer program, when run by a processor, controls the device where the storage medium is located to execute a control method for an air conditioner.

[0023] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: The readable storage medium of the present invention implements the control method of the air conditioner of any technical solution of the present invention, and therefore has all the beneficial effects of the control method of the air conditioner of any technical solution of the present invention, which will not be repeated here.

[0024] By adopting the technical solution of the present invention, the following technical effects can be achieved:

[0025] (1) When the partition is open, the first air duct and the second air duct are combined; when the partition is closed, the first air duct and the second air duct are separated. The opening and closing of the partition is controlled according to the operating parameters of the first condenser and the second condenser, making the control method more reliable and preventing erroneous control of the partition from affecting the normal operation of the air conditioner.

[0026] (2) By comparing the absolute value of the difference |ΔP| with the difference threshold P 阈 The comparison is conducted, and the result is obtained when the absolute value of the difference |ΔP| is greater than or equal to the difference threshold P. 阈 In this case, the high pressure difference between the first condenser and the second condenser is large, indicating that one of the condensers is clogged. Therefore, the condenser group outputs an alarm.

[0027] (3) When the outdoor unit is running, the partition is opened to accelerate the heat dissipation of the condenser. When the outdoor unit stops running, the partition is closed to facilitate the execution of the control method when the air conditioner is turned on again. Attached Figure Description

[0031] Explanation of reference numerals in the attached figures:

[0032] 100: Control device; 110: Judgment module; 120: Acquisition module; 130: Control module. Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] This invention provides a control method for an air conditioner, as shown in the attached figure. Figure 1 As shown, the air conditioner includes an air duct, a fan unit, and a condenser unit. The fan unit includes a first fan and a second fan. The condenser unit includes a first condenser and a second condenser. A movable partition is provided inside the air duct. The partition is opened and closed by moving. The partition is used to divide the air duct into a first air duct corresponding to the first fan and a second air duct corresponding to the second fan.

[0035] Specifically, as shown in the appendix Figure 1 As shown, the control methods include:

[0036] S100, Determine the operating status of the first and second fans;

[0037] S200: Obtain the operating parameters of the first condenser and the second condenser;

[0038] S300: Control the opening and closing of the baffle plate according to the operating parameters of the first condenser and the second condenser.

[0039] Specifically, after determining the operating status of the first fan and the second fan, the control method also includes: if the first fan or the second fan cannot operate, controlling the air conditioner to alarm and controlling the partition to open so that the partition merges the first air duct and the second air duct.

[0040] Specifically, if either the first or second fan fails to operate, the air conditioner will issue an alarm, awaiting after-sales service. The partition will open, merging the first and second air ducts. Another fan that can start normally will then cool both condensers. Using a single fan to cool a clogged condenser cannot alleviate the increased pressure on that side of the refrigeration system. Therefore, to balance the pressure on both sides of the refrigeration system, the first and second air ducts are merged.

[0041] Preferably, when the air conditioner alarms, it can accurately provide alarm information indicating that a specific fan has malfunctioned, making it convenient for maintenance personnel to repair it.

[0042] For example, obtaining the operating parameters of the first condenser and the second condenser specifically includes: controlling the operation of the first condenser and the second condenser for a first time, and obtaining the absolute value |ΔP| of the difference between the high pressure P1 of the first condenser and the second high pressure P2 of the second condenser as the operating parameter.

[0043] For example, by controlling the operation of the first condenser and the second condenser for a certain period of time, the first high-pressure P1 of the first condenser and the second high-pressure P2 of the second condenser are detected. The absolute value of the difference between the first high-pressure P1 and the second high-pressure P2, |ΔP|, is obtained, which makes the judgment of the first condenser and the second condenser more accurate and improves the reliability of the control method.

[0044] Specifically, based on the operating parameters of the first and second condensers, the opening and closing of the baffle is controlled, including: comparing the absolute value of the difference |ΔP| with the difference threshold P. 阈 The comparison is used to control the opening and closing of the partition.

[0045] Specifically, by comparing the absolute value of the difference |ΔP| with the difference threshold P 阈 By comparing and obtaining the comparison results, the reliability of the control method is improved, thereby controlling the opening and closing of the partition.

[0046] Preferably, the difference threshold P 阈 The values ​​are 0.9 MPa, 1.0 MPa, or 1.1 MPa.

[0047] For example, based on the comparison results, controlling the opening and closing of the partition specifically includes: when the absolute value of the difference |ΔP| is greater than or equal to the difference threshold P. 阈 In this case, the control baffle opens and the condenser group alarm is activated; when the absolute value of the difference |ΔP| is less than the difference threshold P 阈 In this case, the control panel closes.

[0048] For example, by comparing the absolute value of the difference |ΔP| with the difference threshold P 阈 The comparison is conducted, and the result is obtained when the absolute value of the difference |ΔP| is greater than or equal to the difference threshold P. 阈 In cases where the high-pressure difference between the first and second condensers is large, indicating a possible blockage in one of the condensers, the condenser assembly will issue an alarm, the baffles will open, and heat dissipation will be accelerated. When the absolute value of the pressure difference, |ΔP|, is less than the difference threshold P... 阈 Under these conditions, the condenser is not clogged, so the air conditioner can operate normally. With the partition closed, the first fan delivers air through the first air duct, and the second fan delivers air through the second air duct.

[0049] For example, controlling the partition to close specifically includes: controlling the partition to close when the partition is open; and / or controlling the partition to remain closed when the partition is closed.

[0050] For example, closing the partition in a timely manner can prevent the first and second fans from interfering with each other when they are running simultaneously.

[0051] For example, the air conditioner also includes an outdoor unit. After the condenser unit alarms, the control method also includes: determining whether the outdoor unit is running; if the outdoor unit is running, controlling the partition to open; if the outdoor unit is off, controlling the partition to close.

[0052] For example, when the outdoor unit is running, the partition opens to accelerate the heat dissipation of the condenser. When the outdoor unit stops running, the partition closes to facilitate the execution of control methods when the air conditioner is turned on again.

[0053] As attached Figure 2 As shown, the air conditioner control method provided by the present invention specifically includes:

[0054] S100, Air conditioner starts;

[0055] S110. Determine the operating status of the first and second fans;

[0056] S200, Control air conditioner alarm;

[0057] S210, Control the opening of the partition;

[0058] In the event that any one of the wind turbines fails to start, S200 and S210 are executed.

[0059] S300: Obtain the operating parameters of the first and second condensers;

[0060] S400, Obtain the absolute value |ΔP| of the difference between the first high-pressure pressure P1 of the first condenser and the second high-pressure pressure P2 of the second condenser as an operating parameter;

[0061] S500, compare the absolute value of the difference |ΔP| with the difference threshold P 阈 Compare;

[0062] S510, Control the opening of the partition;

[0063] Among them, when the absolute value of the difference |ΔP| is greater than or equal to the difference threshold P 阈 In this case, execute S510;

[0064] S520, Control the partition to close;

[0065] Among them, when the absolute value of the difference |ΔP| is less than the difference threshold P 阈 In this case, execute S520;

[0067] S700: Determine if the outdoor unit is running;

[0068] S710, Control the partition to close;
