[0056] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0057] It should be understood that the term "several" in this document refers to one or more, and "multiple" refers to two or more. "And / or" describes the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can mean: A exists alone, A and B exists simultaneously, or B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0058] Generally speaking, in industrial or commercial applications, air conditioning systems often have high operational stability requirements. To prevent air conditioning compressor shutdowns due to power failures, the industry typically chooses a multi-channel power supply solution for the air conditioning compressor, that is, providing the air conditioning compressor with multiple power input ports.

[0059] Please refer to Figure 1 , which shows a system architecture diagram of an air conditioning system provided by an exemplary embodiment of the present application. Figure 1 As shown, the air conditioning system includes: a control device 110, an air conditioning compressor 120, an automatic transfer switch 130, and at least two power input ports 140;

[0060] The control device 110 is electrically connected to the air-conditioning compressor 120 and the automatic transfer switch 130 respectively;

[0061] The automatic transfer switch 130 is provided on the power supply circuit between the air-conditioning compressor and at least two power supply input ports 140 ; ​​and the automatic transfer switch 130 is used to supply power to the air-conditioning compressor 120 through one of the at least two power supply input ports 140 .

[0062] An automatic transfer switch (ATS) is a switching device primarily used in emergency power supply systems to automatically transfer load circuits from one power source to another (backup) power source. The ATS can ensure continuous and reliable operation of critical loads in systems with multiple power supplies.

[0063] In the embodiment of the present application, the at least two power input ports 140 can be powered by the mains electricity. At the same time, in order to avoid the air-conditioning compressor 120 from being unable to work due to a mains power outage, the at least two power input ports 140 can also be switched to a backup generator ( Figure 1 The backup generator is used for power supply, and then switches back to the mains power supply when the mains power is restored.

[0064] The ATS is usually connected to multiple power input ports, each of which is equivalent to a power supply. At the same time, the ATS can maintain connectivity between one power input port and the load circuit (corresponding to the above-mentioned air-conditioning compressor 120).

[0065] The ATS is usually a mechanical structure. When the ATS switches from one power input port to another power input port, the switching time is more than 100 milliseconds, which may cause power failure in the load circuit.

[0066] The air-conditioning compressor 120 can be used to suck low-temperature, low-pressure refrigerant gas from the intake pipe, compress it by driving the piston through the motor, and then discharge high-temperature, high-pressure refrigerant gas to the exhaust pipe, thereby providing power for the refrigeration cycle.

[0067] In an embodiment of the present application, in addition to the air-conditioning compressor 120, the automatic transfer switch 130, and at least two power supply input ports 140, a control device 110 is also provided. The control device 110 can be electrically connected to the air-conditioning compressor 120 and the automatic transfer switch 130, so that messages can be transmitted between the control device 110 and the air-conditioning compressor 120, and between the control device 110 and the automatic transfer switch 130.

[0068] Because the air conditioner compressor's lubrication system is not in optimal condition when the compressor is cold and unactivated, operating it at high speed, or accelerating or decelerating it at high speeds, can easily shorten the compressor's lifespan. Therefore, air conditioner compressor drivers typically include a manufacturer-recommended startup logic. This startup logic specifies the acceleration and deceleration step rates during compressor startup. When the compressor is powered on, the driver follows this startup logic to control the compressor's operating timing.

[0069] For example, a manufacturer-recommended startup logic may have the following rules:

[0070] 1) The driver controls the air conditioning compressor's speed acceleration and deceleration to be less than 3 rps / sec, and the acceleration during shutdown to be less than 10 rps / sec. Rps (revolutions per second) is the unit of speed, and sec is the abbreviation for second.

[0071] 2) After the air conditioner compressor is started, if you want to slow down to below 30rps, you need to run it at 30rps for more than 1 minute before slowing down.

[0072] 3) After the air conditioner compressor is started, if you want to increase the speed to above 50rps, you need to run it at 50rps for more than 3 minutes before increasing the speed.

[0073] It can be seen from the above startup logic that the air-conditioning compressor needs to go through a period of buffering from the start to the normal operation, so that the air-conditioning compressor can be fully lubricated and return oil to avoid affecting the life of the air-conditioning compressor. However, the above buffering time is long, usually taking several minutes (in the above example, a buffering time of more than 4 minutes is required). That is to say, if the air-conditioning compressor is temporarily shut down due to power outage during operation, it is also necessary to preheat and buffer according to the above startup logic when it is restarted. This is often unacceptable for scenarios that require high refrigeration stability; and if a more radical startup logic is directly adopted, it will affect the service life of the air-conditioning compressor.

[0074] In this regard, an embodiment of the present application provides a solution that enables a control device to selectively control the air-conditioning compressor to start in a normal or aggressive manner. The solution is as follows:

[0075] A control device, configured to read first power input status information of the air-conditioning compressor and second power input status information of the automatic transfer switch;

[0076] The control device is further configured to, in response to the first power input status information indicating that the air-conditioning compressor has no power input, and the second power input status information indicating that at least two of the power input ports have no power output, control the air-conditioning compressor to perform an emergency start when power is restored to the air-conditioning compressor;

[0077] The control device is further configured to, in response to the first power input status information indicating that the air-conditioning compressor has no power input and the second power input status information indicating that at least one of the power input ports has power output, control the air-conditioning compressor to perform normal startup when power is restored to the air-conditioning compressor;

[0078] The time length for the air-conditioning compressor to reach the designated working state when performing emergency startup is shorter than the time length for the air-conditioning compressor to reach the designated working state when performing normal startup.

[0079] In an embodiment of the present application, two startup modes are simultaneously set for the air-conditioning compressor. One is an emergency startup mode. In this startup mode, the air-conditioning compressor will quickly reach a working state with good cooling effect (i.e., the above-mentioned designated working state) after startup. In this emergency startup mode, the cooling effect of the air-conditioning compressor is given priority. The other is a normal mode. In this normal mode, it will take a long time for the air-conditioning compressor to reach a working state with good cooling effect after startup. Among them, the normal mode can use the startup logic pre-configured by the air-conditioning compressor manufacturer for the air-conditioning compressor. Under this startup logic, the service life of the air-conditioning compressor is given priority.

[0080] During the operation of the air-conditioning system, the control device can simultaneously obtain the power input status information of the air-conditioning compressor and the power input status information of the automatic transfer switch ATS, and comprehensively determine the reason for the power outage and shutdown of the air-conditioning compressor.

[0081] For example, when the air-conditioning compressor (or the air-conditioning compressor driver) has no power input, it is determined that the air-conditioning compressor is powered off. If at this time, at least one of the two power input ports has power output, it means that the power off of the air-conditioning compressor is caused by the failure of a previous single power input port, or is caused by the ATS switching the power input port. In this case, the air-conditioning compressor will quickly resume power supply. At this time, since the power outage time is short, even if the air-conditioning compressor is started in normal mode, the time from the power off of the air-conditioning compressor to the restart of the air-conditioning compressor to the specified working state will not be too long. Accordingly, during this period of time, the refrigeration area will not have too much temperature difference. At this time, the control device gives priority to the service life of the air-conditioning compressor and controls the air-conditioning compressor to start in normal mode.

[0082] For another example, when the air conditioning compressor has no power input, it is determined that the air conditioning compressor is powered off. If at least two power input ports have no power output at this time, it indicates that the air conditioning compressor power outage may be caused by the main and backup power supply switching (for example, due to the main power outage, the air conditioning system switches from the main power to the generator power generation, or due to the main power restoration, the air conditioning system switches from the generator power generation to the main power). In this case, since the main and backup power supply switching usually takes a long time to complete, the air conditioning compressor may need to be powered off for a long time. In this case, if the air conditioning compressor is still started according to the normal start-up mode, the time from the air conditioning compressor power outage to the air conditioning compressor restarting and reaching the specified working state will also be relatively long. Accordingly, during this time, the cooling area may have a large temperature difference. In this case, the control device needs to prioritize the cooling effect and thus control the air conditioning compressor to start in the emergency start mode. In addition, since in the above scenario, the air conditioning compressor is restarted after power is restored after the power is restored after the air conditioning compressor is powered off during operation, it has been fully lubricated and oil returned during the operation before the power outage. In this case, starting according to the emergency start mode will not have a significant impact on the life of the air conditioning compressor.

[0083] To sum up, in the embodiment of the present application, by setting two starting modes for the air-conditioning compressor, the control device monitors the power input status information of the air-conditioning compressor and the automatic transfer switch at the same time during the operation of the air-conditioning system. When it is detected that there is no power input to the air-conditioning compressor and there is power input in the power input port connected to the automatic transfer switch, it is determined that the air-conditioning compressor will resume power supply at a short time after shutdown. When power is restored subsequently, the air-conditioning compressor is started through the normal mode. When it is detected that there is no power input to the air-conditioning compressor and there is no power input in the power input port connected to the automatic transfer switch, it is determined that it will take a long time for the air-conditioning compressor to resume power supply after shutdown. When power is restored subsequently, the emergency start mode is used to enable the air-conditioning compressor to reach a working state with a better cooling effect more quickly. Therefore, the above scheme can improve the cooling effect of the air-conditioning compressor after shutdown and restart while taking into account the service life of the air-conditioning compressor.

[0084] Please refer to Figure 2 , which shows a flow chart of an air-conditioning compressor control method provided by an exemplary embodiment of the present application. The method can be executed by a computer device, for example, the computer device can be a control device in the above-mentioned air-conditioning system, wherein the air-conditioning system can be a Figure 1 The air conditioning system with the system architecture shown in Figure 1 is as follows. Figure 2 As shown, the method may include the following steps:

[0085] Step 201 : Reading first power input status information of the air-conditioning compressor and second power input status information of the automatic transfer switch.

[0086] Step 202: In response to the first power input status information indicating that the air-conditioning compressor has no power input, and the second power input status information indicating that at least two of the power input ports have no power output, when the air-conditioning compressor resumes power supply, control the air-conditioning compressor to perform emergency startup.

[0087] Step 203: In response to the first power input status information indicating that the air-conditioning compressor has no power input, and the second power input status information indicating that at least one of the power input ports has power output, when the air-conditioning compressor resumes power supply, the air-conditioning compressor is controlled to perform normal startup.

[0088] The time length for the air-conditioning compressor to reach the designated working state when performing emergency startup is shorter than the time length for the air-conditioning compressor to reach the designated working state when performing normal startup.

[0089] The execution process of the above steps 201 to 203 can be referred to Figure 1 The actions performed by the air conditioning equipment in the illustrated embodiment will not be described in detail here.

[0090] To sum up, the scheme shown in the embodiment of the present application sets two starting modes for the air-conditioning compressor, and the control device monitors the power input status information of the air-conditioning compressor and the automatic transfer switch at the same time during the operation of the air-conditioning system. When it is detected that there is no power input to the air-conditioning compressor and there is power input in the power input port connected to the automatic transfer switch, it is determined that the air-conditioning compressor will resume power supply at a short time after shutdown. When power is restored subsequently, the air-conditioning compressor is started through the normal mode. When it is detected that there is no power input to the air-conditioning compressor and there is no power input in the power input port connected to the automatic transfer switch, it is determined that it will take a long time for the air-conditioning compressor to resume power after shutdown. When power is restored subsequently, the emergency start mode is used to enable the air-conditioning compressor to reach a working state with a better cooling effect more quickly. Therefore, the above scheme can improve the cooling effect of the air-conditioning compressor after shutdown and restart while taking into account the service life of the air-conditioning compressor.

[0091] The solutions shown in the above embodiments of the present application can be applied to any air-conditioning system with multiple power supplies. For example, the air-conditioning system in the above solutions of the present application can be an indirect evaporative cooling air-conditioning system.

[0092] Please refer to Figure 3 , which shows a unit structure diagram of an indirect evaporative cooling air conditioning system according to an embodiment of the present application. Indirect evaporative cooling refers to the process of transferring the cooling energy of the moist air (secondary air) obtained by direct evaporative cooling to the air to be treated via a non-direct contact heat exchanger, thereby achieving isohumidification cooling of the air.

[0093] like Figure 3 As shown, the air and water cooled in the direct evaporative cooling process are passed through a non-contact heat exchanger to cool the air to be treated, so that low-temperature air with a lower temperature and unchanged moisture content can be obtained. This process is an isohumid cooling process. The air in direct evaporative cooling is generally called secondary air 31, and the air to be cooled is called primary air 32. In scenarios where the ambient temperature is high and the load is large (such as the computer room of a data center), when the natural cooling mode cannot fully meet the cooling needs of the indirect evaporative cooling unit, it is necessary to turn on the air-conditioning compressor to supplement some of the cooling. In this mode, natural cooling and air-conditioning compressor cooling jointly bear the cooling needs of the indirect evaporative cooling unit. Figure 3 As can be seen from the structural diagram shown, indirect evaporative cooling air conditioning does not have cold storage equipment like water systems, that is, there is no backup cold source. Therefore, rapid recovery of cooling after a fault is particularly important for the normal operation of the cooling environment.

[0094] For indirect evaporative cooling air conditioning systems, since there is no cold storage equipment, when the air conditioning compressor loses power and stops, the cooling effect on the cooling environment will be lost. For scenarios such as data center rooms with high ambient temperatures and heavy loads, the power outage of the air conditioning compressor will quickly cause the temperature of the cooling environment to rise, affecting the operating stability of the equipment in the data center.

[0095] The solution for restarting the air-conditioning compressor after power failure and shutdown provided in the above-mentioned embodiment of the present application can be applied to air-conditioning systems with indirect evaporative cooling. The air-conditioning equipment can be used to detect the power input status of the air-conditioning compressor and the ATS, and the reason for the power failure of the air-conditioning compressor can be determined comprehensively through the power input status of the two. When the air-conditioning compressor is powered off due to the switching of the power input port by the ATS, it is expected that the power supply will be restored soon. At this time, the service life of the air-conditioning compressor is given priority. When the air-conditioning compressor is powered off due to no power input to all power input ports, it is expected that the time to restore the power supply will be longer. At this time, the cooling effect during the startup process after the power is restored is given priority.

[0096] In various embodiments of the present application, the startup strategy used during emergency startup of the air-conditioning compressor can be set in the air-conditioning compressor by the control device.

[0097] Please refer to Figure 4 , which shows a flow chart of an air-conditioning compressor control method provided by an exemplary embodiment of the present application. The method can be executed by a computer device, for example, the computer device can be a control device in the above-mentioned air-conditioning system, wherein the air-conditioning system can be a Figure 1 The air conditioning system with the system architecture shown in Figure 1 is as follows. Figure 4 As shown, the method may include the following steps:

[0098] Step 401: Obtain emergency startup strategy.

[0099] In a possible implementation, the emergency startup strategy may include:

[0100] At least one of the rotational speed acceleration corresponding to at least two acceleration time intervals, and the buffering time between at least two of the acceleration time intervals.

[0101] Optionally, the above-mentioned emergency start strategy may also include the length of time the air-conditioning compressor maintains the specified working state after reaching the specified working state. That is to say, during emergency start-up, the air-conditioning compressor reaches the specified working state and maintains it for a certain length of time before entering the normal working state, thereby ensuring the cooling effect in the emergency start-up state.

[0102] In an embodiment of the present application, in order to quickly start the air-conditioning compressor in emergency start mode while also taking into account the service life of the air-conditioning compressor, multiple acceleration time intervals can be set in the emergency start strategy. In each acceleration time interval, the air-conditioning compressor accelerates according to the corresponding speed acceleration. At the end of the acceleration time interval, the speed is maintained unchanged. After a period of buffering, the speed is increased again in the next acceleration time interval. In this way, the cycle of acceleration-smooth operation-acceleration is used to minimize the impact on the service life of the air-conditioning compressor. The speed acceleration in each acceleration time interval can be the same or different.

[0103] In an embodiment of the present application, the above-mentioned emergency start strategy can indicate the speed acceleration within each acceleration time interval, or can indicate the buffer time between two adjacent acceleration time intervals, or can indicate the speed acceleration within each acceleration time interval and the buffer time between two adjacent acceleration time intervals at the same time.

[0104] In addition to the emergency start strategy, in embodiments of the present application, the air conditioning compressor also has a normal start strategy. In this normal start strategy, multiple acceleration time intervals and buffer periods between adjacent acceleration time intervals can also be set. Unlike the normal start strategy, the speed acceleration corresponding to each acceleration time interval in the emergency start strategy can be higher, or the buffer period in the emergency start strategy can be shorter, or both the speed acceleration corresponding to each acceleration time interval in the emergency start strategy can be higher and the buffer period in the emergency start strategy can be shorter.

[0105] In another possible implementation, the buffer time may not be set in the emergency start mode. For example, only one acceleration time interval is set in the emergency start mode. During the acceleration time interval, the speed of the air-conditioning compressor can continue to increase (linearly or nonlinearly) until the specified working state is reached.

[0106] In another possible implementation, the emergency start strategy may further include a speed acceleration of the air-conditioning compressor when it is decelerating (that is, deceleration is performed at this speed acceleration).

[0107] In a possible implementation, obtaining the emergency startup strategy includes:

[0108] The emergency startup policy sent by the configuration device is received, where the emergency startup policy is configured by the user in a policy configuration interface displayed by the configuration device.

[0109] In an embodiment of the present application, the above-mentioned emergency start-up strategy can be configured by the user. For example, the user can set the above-mentioned emergency start-up strategy according to the environmental parameters of the current environment (such as at least one of the ambient temperature and ambient humidity). For example, the user can set the speed acceleration within each acceleration time interval in the above-mentioned emergency start-up strategy, or the user can also set the buffer time between each acceleration time interval.

[0110] For example, the configuration device and the control device are connected through a communication interface that supports a preset communication protocol, which can be a private protocol or a public protocol; the configuration device can provide a human-machine interface (HMI), and the user can configure various parameters in the emergency startup strategy in the HMI. After the user configuration is completed, the configuration device can generate the corresponding emergency startup strategy and send the emergency startup strategy to the control device.

[0111] In the embodiment of the present application, the configuration device and the control device may be the same physical device or different physical devices.

[0112] In a possible implementation, obtaining the emergency startup strategy includes:

[0113] Acquiring environmental parameters of the air conditioning system, where the environmental parameters include at least one of ambient temperature and ambient humidity;

[0114] Based on the environmental parameters, the emergency startup strategy is generated.

[0115] In an embodiment of the present application, the emergency start strategy can also be automatically configured by the control device. For example, the control device can be connected to or have a built-in temperature and humidity sensor, which collects at least one of the ambient temperature and humidity parameters through the temperature and humidity sensor, and calculates various parameters in the emergency start strategy based on the collected at least one of the ambient temperature and humidity parameters, and generates the emergency start strategy based on the calculated parameters.

[0116] For example, an algorithm for calculating various parameters of the emergency startup strategy can be pre-set in the control device. After the control device collects environmental parameters, the collected environmental parameters are input into the above algorithm to obtain the algorithm output, which are various parameters of the emergency startup strategy.

[0117] The algorithm for calculating the parameters of the emergency startup strategy can be pre-set in the control device by a developer or can be set by a user.

[0118] Step 402: Send the emergency start strategy to the air-conditioning compressor so that the air-conditioning compressor stores the emergency start strategy.

[0119] In an embodiment of the present application, after the control device obtains the emergency start-up strategy, it can configure the emergency start-up strategy to the air-conditioning compressor, for example, send it to the control board in the air-conditioning compressor, and store it by the control board in the air-conditioning compressor.

[0120] In one possible implementation, the normal startup strategy of the above-mentioned air-conditioning compressor can directly use the startup strategy pre-set by the manufacturer of the air-conditioning compressor in the control panel of the air-conditioning compressor; or, the above-mentioned normal startup strategy can also be obtained by the control device and configured to the air-conditioning compressor; wherein, the process of the control device obtaining and configuring the normal startup strategy to the air-conditioning compressor can be similar to the process of obtaining and configuring the emergency startup strategy to the air-conditioning compressor, which will not be repeated here.

[0121] Step 403 : Read the first power input status information of the air-conditioning compressor and the second power input status information of the automatic transfer switch.

[0122] In an embodiment of the present application, during the operation of the air-conditioning system, the control device can read power input status information from the air-conditioning compressor and the automatic transfer switch respectively.

[0123] The first power input status information is used to indicate whether there is power input for controlling the air-conditioning compressor, and the second power input status information can be used to indicate whether at least two power input ports connected to the ATS have power output.

[0124] The control device may read the first power input status information and the second power input status information in real time or at a certain period (e.g., every 0.5 seconds). Furthermore, the control device may read the first power input status information and the second power input status information simultaneously.

[0125] Step 404: In response to the first power input status information indicating that the air-conditioning compressor has no power input, and the second power input status information indicating that at least two of the power input ports have no power output, when the air-conditioning compressor resumes power supply, control the air-conditioning compressor to perform emergency startup.

[0126] In a possible implementation, when the air-conditioning compressor recovers power, controlling the air-conditioning compressor to perform emergency startup includes:

[0127] When the air-conditioning compressor resumes power supply, an emergency start instruction is sent to the air-conditioning compressor, where the emergency start instruction is used to instruct the air-conditioning compressor to perform an emergency start based on a stored emergency start strategy.

[0128] In an embodiment of the present application, when the control device determines that the air-conditioning compressor needs emergency start-up, it can send an emergency start-up instruction to the air-conditioning compressor. After the control board of the air-conditioning compressor receives the emergency start-up instruction, it can use the emergency start-up strategy to execute the emergency start-up to quickly reach the specified working state and achieve rapid cooling after power failure recovery.

[0129] In a possible implementation, when the air-conditioning compressor recovers power, controlling the air-conditioning compressor to perform emergency startup includes:

[0130] When the air-conditioning compressor is restored to power, obtain the power-off duration of the air-conditioning compressor;

[0131] In response to the power outage duration being within a specified duration range, the air-conditioning compressor is controlled to perform emergency start.

[0132] In an embodiment of the present application, the power-off duration of the air-conditioning compressor can also assist the control device in determining whether to start the air-conditioning compressor through an emergency start. For example, a specified time range is pre-set in the control device. When the power-off duration of the air-conditioning compressor is less than the minimum value of the specified time range, it indicates that the power-off duration of the air-conditioning compressor is short. In this case, the cooling demand can be met without emergency start. When the power-off duration of the air-conditioning compressor is greater than the maximum value of the specified time range, it indicates that the power-off duration of the air-conditioning compressor is long. In this case, even if emergency start is used, the meaning of rapid cooling may be lost due to the high temperature in the cooling environment (for example, in a data center, a downtime may occur due to the long power-off duration of the air-conditioning compressor). When the power-off duration of the air-conditioning compressor is within the specified time range, the temperature of the cooling environment has increased due to the power-off of the air-conditioning compressor, and no irreversible impact has been caused on the cooling environment. In this case, the air-conditioning compressor needs to be quickly started to quickly cool the cooling environment.

[0133] In a possible implementation, before reading the first power input status information of the air-conditioning compressor and the second power input status information of the automatic transfer switch, the method further includes:

[0134] The duration configuration information sent by the configuration device is received. The duration configuration information is configured by the user in a duration configuration interface displayed by the configuration device, and the duration configuration information is used to indicate the specified duration range.

[0135] In a possible implementation, before reading the first power input status information of the air-conditioning compressor and the second power input status information of the automatic transfer switch, the method further includes:

[0136] Acquiring environmental parameters of the air conditioning system, where the environmental parameters include at least one of ambient temperature and ambient humidity;

[0137] The specified time range is obtained based on the environment parameters.

[0138] In the embodiment of the present application, the process of the control device obtaining the above-mentioned duration configuration information is similar to the process of obtaining the above-mentioned emergency startup strategy, and will not be repeated here.

[0139] In a possible implementation, the policy configuration interface and the duration configuration interface may be the same interface, or the policy configuration interface and the duration configuration interface may be different interfaces.

[0140] For example, please refer to Figure 5 , which shows a schematic diagram of a configuration interface involved in an embodiment of the present application. Figure 5 In the configuration interface 51, the user can configure the shortest power-off time of the compressor quick start mode window (i.e., the lower limit / minimum value of the above-mentioned specified time range), the longest power-off time of the compressor quick start mode window (i.e., the upper limit / maximum value of the above-mentioned specified time range), the compressor acceleration rate and the compressor deceleration rate (i.e., the speed acceleration within the above-mentioned each acceleration time interval), and the compressor 80% speed maintenance time (i.e., the time the air-conditioning compressor maintains the specified working state after reaching the specified working state).

[0141] Step 405: In response to the first power input status information indicating that the air-conditioning compressor has no power input, and the second power input status information indicating that at least one of the power input ports has power output, when the air-conditioning compressor resumes power supply, control the air-conditioning compressor to perform normal startup.

[0142] The time length for the air-conditioning compressor to reach the designated working state when performing emergency startup is shorter than the time length for the air-conditioning compressor to reach the designated working state when performing normal startup.

[0143] The designated working state is used to indicate that the rotation speed of the air-conditioning compressor is a designated rotation speed.

[0144] In a possible implementation, the control device may further perform the following steps:

[0145] During the emergency start-up of the air-conditioning compressor, obtaining the real-time speed of the air-conditioning compressor;

[0146] Based on the real-time speed of the air-conditioning compressor, obtaining operating parameters of auxiliary function components of the air-conditioning system;

[0147] Controlling the operation of the auxiliary function component based on the operating parameters of the auxiliary function component;

[0148] The auxiliary function component includes at least one of an evaporator, a condenser, an electronic expansion valve and a fan.

[0149] Please refer to Figure 6 and Figure 7 ,in, Figure 6 The following is a workflow framework diagram of the air-conditioning system involved in the embodiment of the present application. Figure 7 A flow chart of the air-conditioning compressor startup control involved in an embodiment of the present application is shown.

[0150] Taking the solution shown in the embodiment of the present application as an example of an air conditioning system in a computer room of a data center, the user can set the time window of the emergency start mode of the air conditioning compressor - the shortest power-off time, the time window - the longest effective time, the acceleration rate and other parameters in the HMI interface according to the load rate of the computer room and the current ambient temperature and humidity. The emergency start mode will be activated within the time window. The HMI interface can be as described above. Figure 5 shown.

[0151] The Quick Start Mode Time Window (minimum power-off time) can be selected by the user based on the current load rate and ambient temperature and humidity of the computer room. If the computer room load is light and the ambient temperature and humidity are low, then normal restart after a short interruption of the air conditioner compressor can still ensure cooling. In this case, this value can be slightly increased. For example, the default recommended value is 0.5 minutes.

[0152] The maximum effective time window for the fast start mode is related to the current load rate of the computer room and the maximum duration that the cooling system can maintain operation in the event of a cooling interruption. If the computer room experiences a long power outage and the equipment in the computer room has overheated and shut down, the fast start of the compressor after power is restored will not be very effective. The default recommended value for this value is 15 minutes.

[0153] Users can freely set the compressor acceleration rate according to the unit compressor model parameters. The default recommended value is 5rps / s.

[0154] Users can also freely set the maintenance time after the compressor reaches the target 80% speed as needed, and then enter the mode adjusted according to the cooling needs of the computer room. The default recommended value is 3 minutes.

[0155] Please refer to Figure 6 and Figure 7 , control equipment (such as Figure 6 The unit main controller 61 in the HMI interface sends the emergency start strategy to the compressor through the internal protocol according to the configuration parameters of the user in the HMI interface. After the emergency start strategy is configured for the air-conditioning compressor, the power input status information of the ATS (the power supply status of the dual power supply) and the input power status information of the air-conditioning compressor (which can be the driver of the air-conditioning compressor) are read simultaneously through the internal communication protocol. When the air-conditioning compressor driver is powered off (such as Figure 7 In step S71), it is comprehensively determined whether the power failure of the air-conditioning compressor is caused by the intermittent switching of the ATS or the power failure of both input power supplies of the unit (taking the dual input power supply as an example) (e.g. Figure 7 In step S72), when both input power sources are powered off, when the air-conditioning compressor is powered on, it is determined whether the power-off duration is within the time window set in the HMI interface (such as Figure 7 If so, the emergency start mode needs to be activated (e.g. Figure 7 Otherwise, start in normal startup mode (such as step S74 in FIG. Figure 7 Step S75 in the process) distinguishes between the normal start mode and the emergency start mode, limits the emergency start of the air-conditioning compressor to specific working conditions, and protects the service life of the compressor as much as possible.

[0156] In the air-conditioning compressor driver, the startup mode is divided into normal startup mode and emergency startup mode. In emergency startup mode, since the air-conditioning compressor goes from running state to power off and then restarts, the air-conditioning compressor system has been preheated and lubricated. Therefore, the acceleration step rate can be allowed to be within 10rps / sec (user-configurable on the HMI, recommended value 5rps / sec). This allows the air-conditioning compressor to quickly start to 80% of the rated speed in 30 seconds without causing too much damage to the air-conditioning compressor itself (taking the maximum speed of 120rps as an example, the rated speed is generally 100rps, and 80% of the rated speed is 80rps).

[0157] For example, see Figure 8, which shows a schematic diagram of the speed of the emergency start mode involved in the embodiment of the present application. In the emergency start mode, the air-conditioning compressor starts from power failure to power restoration. The reset time of the air-conditioning compressor control panel is generally about 7 seconds. The compressor accelerates to 40rps at a rate of 5rps / sec. After running smoothly for 5s, it can be accelerated to 90rps at a rate of 5rps / sec. The total time consumed is less than 30s. The parameter values ​​in the implementation of this application are an exemplary solution. For different models of compressors, different acceleration rates can be set in the HMI interface according to actual needs.

[0158] like Figure 6 As shown in the figure, after the compressor speed is adjusted, the fan speed of the refrigeration system, the opening of the electronic expansion valve and other components are adjusted automatically by the unit controller according to the condenser pressure, evaporation superheat and other parameters, so that the compressor can output the corresponding cooling capacity at the corresponding speed.

[0159] like Figure 7 As shown, after the air conditioner compressor reaches 80% of the rated speed, it maintains a period of stable operation (such as Figure 7 Then, the unit controller enters the normal PID adjustment mode for the compressor speed according to the cooling demand of the machine room (e.g. Figure 7 Step S77 in the process).

[0160] The solution shown in the embodiments of this application divides the air conditioner compressor's startup mode into normal startup mode and emergency startup mode. In emergency startup mode, the compressor can quickly start up to 80% of the rated speed in 30 seconds without causing significant damage to the compressor itself. While this mode may have a certain impact on the compressor's service life, in temperature-sensitive scenarios such as data centers, as an emergency measure, protecting the computer room load should be prioritized.

[0161] In addition, this solution uses the unit controller and the communication protocol to simultaneously read the ATS input power status information and the compressor driver input power status information, and comprehensively judge whether the power outage of the compressor is caused by the intermittent switching of the ATS or the power outage of both input power lines of the unit. When both input power lines are out of power, the compressor needs to activate the emergency quick start mode, thereby distinguishing between the normal start mode and the emergency start mode, reducing the number of times the compressor emergency start is triggered, and protecting the compressor service life as much as possible.

[0162] In addition, users of this solution can freely set the minimum power-off time and maximum effective time for the compressor quick start mode to take effect through the unit's HMI human-machine interface, combined with the current actual load rate and environmental conditions of the computer room, and can manually turn the above-mentioned emergency start mode on and off according to on-site operation and maintenance inspections.

[0163] To sum up, the scheme shown in the embodiment of the present application sets two starting modes for the air-conditioning compressor, and the control device monitors the power input status information of the air-conditioning compressor and the automatic transfer switch at the same time during the operation of the air-conditioning system. When it is detected that there is no power input to the air-conditioning compressor and there is power input in the power input port connected to the automatic transfer switch, it is determined that the air-conditioning compressor will resume power supply at a short time after shutdown. When power is restored subsequently, the air-conditioning compressor is started through the normal mode. When it is detected that there is no power input to the air-conditioning compressor and there is no power input in the power input port connected to the automatic transfer switch, it is determined that it will take a long time for the air-conditioning compressor to resume power after shutdown. When power is restored subsequently, the emergency start mode is used to enable the air-conditioning compressor to reach a working state with a better cooling effect more quickly. Therefore, the above scheme can improve the cooling effect of the air-conditioning compressor after shutdown and restart while taking into account the service life of the air-conditioning compressor.

[0164] In one possible implementation, the solution shown in the embodiment of the present application can be a cloud technology service. For example, the air-conditioning system shown in the embodiment of the present application can provide cooling function for cloud devices. For example, the data center in the above embodiment can be a data center operating based on cloud technology.

[0165] In one possible implementation, the solution shown in the embodiment of the present application can be implemented in combination with cloud technology. For example, the above-mentioned control device can be implemented as a server, wherein the server can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, content distribution networks, and big data and artificial intelligence platforms.

[0166] Alternatively, the configuration information in the scheme shown in the embodiment of the present application, such as the above-mentioned emergency startup strategy and duration configuration information, can be obtained by the configuration device after the user's configuration is generated and uploaded to the cloud, obtained by the control device from the cloud, and configured to the air-conditioning compressor.

[0195] In a possible implementation, the designated operating state is used to indicate that the rotational speed of the air-conditioning compressor is a designated rotational speed.

[0196] To sum up, the scheme shown in the embodiment of the present application sets two starting modes for the air-conditioning compressor, and the control device monitors the power input status information of the air-conditioning compressor and the automatic transfer switch at the same time during the operation of the air-conditioning system. When it is detected that there is no power input to the air-conditioning compressor and there is power input in the power input port connected to the automatic transfer switch, it is determined that the air-conditioning compressor will resume power supply at a short time after shutdown. When power is restored subsequently, the air-conditioning compressor is started through the normal mode. When it is detected that there is no power input to the air-conditioning compressor and there is no power input in the power input port connected to the automatic transfer switch, it is determined that it will take a long time for the air-conditioning compressor to resume power after shutdown. When power is restored subsequently, the emergency start mode is used to enable the air-conditioning compressor to reach a working state with a better cooling effect more quickly. Therefore, the above scheme can improve the cooling effect of the air-conditioning compressor after shutdown and restart while taking into account the service life of the air-conditioning compressor.
