[0028] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments only represent some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort also belong to the protection scope of the present application.

[0029] In the embodiments of the present application, the space conditioning object can be a device capable of adjusting the temperature in the space; for example, Figure 1(is a structural diagram of a space conditioning object provided by an embodiment of the present application), the space conditioning object may include a variable frequency compression device, a condenser, an evaporator, a wet film, an air outlet fan, and an air supply fan. Among them, the variable frequency compression device may include a frequency converter and a compressor. The compressor is a machine that compresses gas or liquid and can transmit it. The main components of the compressor include a compression chamber, a cylinder, a piston, a crankshaft, a cooler and a motor. The frequency converter is an electric power conversion device used to control the speed, output power and current of the AC motor. Therefore, the frequency converter can control the speed of the motor driving the compressor by changing the operating frequency of the motor in the compressor (that is, the operating frequency of the compressor described below). In the refrigeration cycle, low-temperature and low-pressure gaseous refrigerant can be sucked into the compressor and compressed into a high-temperature and high-pressure refrigerant gas. After being discharged from the compressor, the refrigerant gas enters the condenser. At this time, the outdoor air can be blown to the condenser through the air outlet fan, so that the refrigerant gas is gradually converted into a refrigerant liquid. The refrigerant liquid after condensation is in a high-temperature and high-pressure state. Among them, as Figure 1 As shown, a spray system can also spray water onto the wet film (or directly onto the condenser). The outdoor air passing through the wet film can fully contact the spray water, effectively utilizing the vaporization of water to lower the air temperature and increase the air humidity, making the temperature of the air blowing to the condenser even lower. The condensed high-pressure refrigerant liquid (which can pass through the expansion valve) enters the evaporator. The indoor air flow (i.e., indoor return air) exchanges heat with the evaporator through the supply fan (after the heat exchange is completed, the air flow is sent to the indoor space through the air supply port, thereby regulating the indoor temperature), converting the refrigerant liquid into low-temperature, low-pressure vapor. This low-temperature, low-pressure vapor will re-enter the compressor through the suction pipe, starting the next round of the refrigeration cycle. Figure 1 The structure shown is only an example, and the specific structure may also include other components, such as a fluorine pump and other components. The structure of the space conditioning object such as the air conditioner in this application is not limited.

[0030] When the compressor has problems including but not limited to excessive discharge pressure, excessive discharge temperature, and excessively low suction pressure, the compressor is shut down to protect the compressor device from damage, resulting in a lack of cooling capacity for the space conditioning object. Based on this, the embodiments of the present application propose a management scheme for a space conditioning object. The processing logic of the management scheme for the space conditioning object is as follows: detecting parameters (such as discharge pressure parameters, discharge temperature parameters, and suction pressure parameters) of the compressor in the space conditioning object when the compressor is in an operating state are obtained, different control strategies are adopted to perform frequency modulation processing (i.e., adjusting the motor speed of the compressor) on the compressor by evaluating the protection interval range of the detection parameters, so as to reduce the probability of compressor failure alarm. For example, increasing the motor speed of the compressor can increase the discharge pressure parameter of the compressor. If the alarm value of the discharge pressure parameter is 41.5 bar (a unit of gas pressure), the motor speed of the compressor can be reduced when the discharge pressure parameter reaches 39 bar to avoid the discharge pressure parameter of the compressor reaching 41.5 bar. In this way, the lack of cooling capacity caused by the shutdown of the compressor due to failure can be effectively avoided, and the stability of the space conditioning object can be improved.

[0031] The management scheme for the space conditioning object provided by the embodiments of the present application can be applied to various fields or scenarios such as cloud technology, artificial intelligence, Internet of Vehicles, intelligent transportation, smart home, etc. In one embodiment, the management scheme for the space conditioning object can be applied to a cloud technology scenario. The management scheme for the space conditioning object can be specifically applied to cloud technology implementation involved in the cloud technology scenario; for example, the cloud server manages the space conditioning object, etc.

[0032] Cloud technology refers to a hosting technology that unifies a series of resources such as hardware, software, and network to realize data calculation, storage, processing, and sharing in a wide area network or local area network. Cloud technology is a general term for network technology, information technology, integration technology, management platform technology, and application technology based on the cloud computing business model application, which can form a resource pool for on-demand use and flexible convenience. Cloud computing technology will become an important support. The background service of a technical network system requires a large amount of computing and storage resources, such as video websites, picture websites, and more portals. With the high development and application of the Internet industry, every item may have its own identification mark in the future, which needs to be transmitted to the background system for logical processing. Different levels of data will be processed separately, and various industry data need strong system support, which can only be realized through cloud computing.

[0033] See Figure 2 , Figure 2 is a system architecture diagram provided by the embodiments of the present application; asFigure 2 As shown, the system architecture includes a control server 20 and a space conditioning object 21 (one or more, three are shown as an example). In an embodiment, the space conditioning object 21 can be applied in a data center to dissipate heat from a machine room of the data center. The data center can be a data center in the field of cloud technology, for example, a cloud computing data center, a cloud storage data center, a cloud security data center, etc. The control server 20 can manage the operating state of the space conditioning object 21 (such as controlling the opening and closing of the space conditioning object 21), and can detect the state parameters of devices such as fans and compressors in real time.

[0034] The control server 20 can be a server with data processing function. The server can be a standalone physical server, a server cluster (such as a container data center) or a distributed system formed by multiple physical servers, or a cloud server providing basic cloud computing services such as cloud service, cloud database, cloud computing, cloud function, cloud storage, network service, cloud communication, middleware service, domain name service, security service, content delivery network (CDN), and big data and artificial intelligence platform. The space conditioning object 21 can be a system with temperature and humidity regulation, such as an air conditioning system. Figure 2 As shown, the space conditioning object 21 and the control server 20 are connected through a network. The space conditioning object 21 can be one or more, and the number of space conditioning objects 21 is not limited in the present application. For example, when the space conditioning object 21 is applied to dissipate heat from a machine room in a data center, the space conditioning object 21 can be dozens.

[0035] Figure 2 The system architecture shown can implement the space conditioning object management scheme provided by the embodiments of the present application. The implementation process of the scheme generally includes: the control server 20 detects the detection parameters (such as discharge pressure parameters and discharge temperature parameters) of the compressor in the space conditioning object 21 in real time when the compressor is in an operating state. If the detection parameters are in a first protection interval, a first control strategy for controlling the compressor is determined, and the compressor is controlled to perform frequency modulation processing according to the first control strategy until the detection parameters are adjusted to be in a second protection interval. If the detection parameters are in the second protection interval, a second control strategy for controlling the compressor is determined, and the compressor is controlled to perform frequency modulation processing based on the target speed of the compressor according to the second control strategy.

[0036] In an optional implementation, the space conditioning object 21 is built-in with a control chip (such as a processor). The space conditioning object management scheme provided by the embodiments of the present application can be executed by the space conditioning object 21, that is, the space conditioning object 21 executes the operations performed by the control server 20.

[0037] It can be understood that the structural schematic diagram of the space adjustment object and the system architecture schematic diagram described in the embodiments of the present application are for more clearly illustrating the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application.

[0038] The related data collection and processing in the embodiments of the present application should strictly comply with the requirements of relevant laws and regulations, and the personal information should be obtained with the knowledge or consent of the personal subject (or with the legal basis for information acquisition), and the subsequent data use and processing behavior should be carried out within the scope of authorization of laws and regulations and personal information subjects. For example, when the embodiments of the present application are applied to specific products or technologies, the permission or consent of the user needs to be obtained, and the collection, use and processing of related data need to comply with relevant laws, regulations and standards in the relevant region.

[0039] Based on the above-described space adjustment object management scheme, the embodiments of the present application propose a more detailed space adjustment object management method, which will be described in detail below in combination with the accompanying drawings. Please refer to Figure 3 , Figure 3 is a flowchart of a space adjustment object management method provided by the embodiments of the present application. The space adjustment object management method includes the following steps S301-S303:

[0040] S301, acquiring detection parameters of a compressor in the space adjustment object when the compressor is in a running state.

[0041] The space conditioning object can be used to adjust the temperature in the space; the space conditioning object includes a compressor, which can be used to compress the low-temperature and low-pressure refrigerant gas into high-temperature and high-pressure refrigerant gas. The embodiments of the present application can obtain the detection parameter of the compressor in the space conditioning object when the compressor is in the running state. In one embodiment, the alarm mechanism of the compressor can be obtained, and the parameter type to which the alarm value in the alarm mechanism belongs is determined as the parameter type to which the detection parameter belongs, and the detection parameter is determined by using the parameter type to which the detection parameter belongs. For example, the alarm mechanism of the compressor includes: the exhaust high-pressure alarm value is 41.4 bar, the exhaust high-temperature alarm value is 115°C (a temperature unit), and the suction low-pressure alarm value is 2.5 bar. Therefore, the detection parameter can include any one of the exhaust pressure parameter belonging to the exhaust pressure type, the exhaust temperature parameter belonging to the exhaust temperature type, and the suction pressure parameter belonging to the suction pressure type. Among them, the exhaust pressure parameter refers to the pressure of the refrigerant gas at the running outlet of the compressor, which can be detected by arranging a pressure sensor at the running outlet of the compressor. The exhaust temperature parameter refers to the temperature of the refrigerant gas at the running outlet of the compressor, which can be detected by arranging a temperature sensor at the running outlet of the compressor. The suction pressure parameter refers to the pressure of the refrigerant gas at the running inlet of the compressor, which can be detected by arranging a pressure sensor at the running inlet of the compressor.

[0042] It should be noted that when the exhaust pressure parameter reaches the exhaust high-pressure alarm value, the compressor will be shut down due to the occurrence of the exhaust high-pressure alarm; when the exhaust temperature parameter reaches the exhaust high-temperature alarm value, the compressor will be shut down due to the occurrence of the exhaust high-temperature alarm; and when the suction pressure parameter reaches the suction low-pressure alarm value, the compressor will be shut down due to the occurrence of the suction low-pressure alarm, which causes a certain lack of cooling capacity of the space conditioning object. Among them, the exhaust high-pressure alarm value, the exhaust high-temperature alarm value, and the suction low-pressure alarm value can be determined according to the system default value of the space conditioning object; for example, the air conditioning system will set the exhaust high-pressure alarm value, the exhaust high-temperature alarm value, and the suction low-pressure alarm value for the air conditioning system before leaving the factory.

[0043] The suction and exhaust pressure ratio refers to the ratio between the exhaust pressure parameter and the suction pressure parameter (i.e. the exhaust pressure parameter / suction pressure parameter), which can be used to reflect the working efficiency of the compressor. In one implementation, obtaining the detection parameter of the compressor in the space conditioning object when the compressor is in the running state includes: obtaining the suction and exhaust pressure ratio of the compressor in the space conditioning object when the compressor is in the running state. It can be understood that when the suction and exhaust pressure ratio is too low, it may cause the space conditioning object to be unable to run normally or the refrigeration effect to be poor.

[0044] S302, if the detection parameter is in the first protection interval, a first control strategy for controlling the compressor is determined, and the compressor is controlled to perform frequency modulation according to the first control strategy until the detection parameter is adjusted to be in the second protection interval.

[0045] It should be noted that increasing the motor speed of the compressor (i.e., performing frequency increase processing on the working frequency of the compressor) can increase the exhaust pressure and the exhaust temperature, at which time the refrigerant flow rate in the refrigeration cycle is accelerated and the refrigeration effect is better, and decreasing the motor speed of the compressor (i.e., performing frequency decrease processing on the working frequency of the compressor) can decrease the exhaust pressure and the exhaust temperature. At the same time, increasing the motor speed of the compressor can also decrease the suction pressure (possibly because the refrigerant gas is insufficient due to excessive gas consumption), and therefore the suction pressure can be increased by decreasing the motor speed of the compressor.

[0046] In one embodiment, the parameter type to which the detection parameter belongs needs to be obtained, and the first protection interval and the second protection interval are obtained according to the parameter type to which the detection parameter belongs. The detection parameter includes any one of an exhaust pressure parameter belonging to an exhaust pressure type, an exhaust temperature parameter belonging to an exhaust temperature type, a suction pressure parameter belonging to a suction pressure type, and a suction-exhaust pressure ratio belonging to a suction-exhaust type. The following will be described by taking the exhaust pressure parameter, the exhaust temperature parameter, the suction pressure parameter, and the suction-exhaust pressure ratio as examples:

[0047] 1. The detection parameter is the exhaust pressure parameter, and the first protection interval of the exhaust pressure parameter is determined according to the exhaust high-pressure protection adjustment value, the first value, and the exhaust high-pressure warning value. The first protection interval of the exhaust pressure parameter is greater than or equal to the exhaust high-pressure protection adjustment value + the first value and less than the exhaust high-pressure warning value (i.e., [exhaust high-pressure protection adjustment value + first value, exhaust high-pressure warning value]). The second protection interval of the exhaust pressure parameter is determined according to the exhaust high-pressure protection adjustment value and the first value. The second protection interval of the exhaust pressure parameter is greater than or equal to the exhaust high-pressure protection adjustment value and less than the exhaust high-pressure protection adjustment value + the first value (i.e., [exhaust high-pressure protection adjustment value, exhaust high-pressure protection adjustment value + first value]). The sum of the exhaust high-pressure protection adjustment value and the first value (i.e., exhaust high-pressure protection adjustment value + first value) is less than the exhaust high-pressure warning value.

[0048] In an implementation manner, the exhaust high-pressure protection adjustment value and the first value can be a default value set by a person, for example, the exhaust high-pressure protection adjustment value is 38 bar and the first value is 1 bar, so that the first protection interval of the exhaust pressure parameter is [39, 41.4), and the second protection interval of the exhaust pressure parameter is [38, 39).

[0049] In another implementation, the exhaust high-pressure protection adjustment value and the first value can be dynamically adjusted according to a difference between an actual ambient temperature (i.e., an actual temperature in the space) and a set temperature (a required ambient temperature). Specifically, the greater the difference between the actual ambient temperature and the set temperature (indicating the greater the refrigeration requirement), the greater the exhaust high-pressure protection adjustment value and the greater the first value; the smaller the difference between the actual ambient temperature and the set temperature (indicating the smaller the refrigeration requirement), the smaller the exhaust high-pressure protection adjustment value and the smaller the first value. For example, when the difference between the actual ambient temperature and the set temperature is 9°C, the exhaust high-pressure protection adjustment value is 38 bar, and the first value is 1 bar (at this time, the second protection interval is [38, 39)); when the difference is 5°C, the exhaust high-pressure protection adjustment value is 37 bar, and the first value is 0.9 bar (at this time, the second protection interval is [36, 37.9)). This is because, when the exhaust pressure parameter is in the first protection interval of the exhaust pressure parameter, the compressor can be controlled to perform frequency reduction processing (i.e., to reduce the motor speed of the compressor) until the exhaust pressure parameter is adjusted to the second protection interval of the exhaust pressure parameter, and then the compressor can be controlled to perform frequency fixing processing (e.g., the motor speed of the compressor is unchanged). When the refrigeration requirement is greater, the compressor will perform frequency fixing operation at a greater working frequency; when the refrigeration requirement is smaller, the compressor will perform frequency fixing operation at a smaller working frequency. For example, when the exhaust pressure parameter drops to [38, 39), the motor speed of the compressor is reduced to 500 revolutions per minute, and the motor speed of the compressor can work at 500 revolutions per minute; when the exhaust pressure parameter drops to [36, 37.9), the motor speed of the compressor is reduced to 400 revolutions per minute, and the motor speed of the compressor can work at 400 revolutions per minute.

[0050] 2. The detection parameter is an exhaust temperature parameter, and the first protection interval of the exhaust temperature parameter is determined according to an exhaust high-temperature protection adjustment value, a second value, and an exhaust high-temperature warning value. Specifically, the first protection interval of the exhaust temperature is greater than or equal to the exhaust high-temperature protection adjustment value + the second value and less than the exhaust high-temperature warning value (i.e., [exhaust high-temperature protection adjustment value + second value, exhaust high-temperature warning value]). The second protection interval of the exhaust temperature parameter is determined according to the exhaust high-temperature protection adjustment value and the second value. Specifically, the second protection interval of the exhaust temperature is greater than or equal to the exhaust high-temperature protection adjustment value and less than the exhaust high-temperature protection adjustment value + the second value (i.e., [exhaust high-temperature protection adjustment value, exhaust high-temperature protection adjustment value + second value]). The sum of the exhaust high-temperature protection adjustment value and the second value (i.e., the exhaust high-temperature protection adjustment value + the second value) is less than the exhaust high-temperature warning value.

[0051] In an implementation, the exhaust gas high temperature protection adjustment value and the second value can be a default value set by a user, for example, the exhaust gas high temperature protection adjustment value is 105°C and the second value is 5°C, and the first protection interval of the exhaust gas temperature parameter is [110, 115), and the second protection interval of the exhaust gas temperature parameter is [105, 110).

[0052] In another implementation, the exhaust gas high temperature protection adjustment value and the second value can be dynamically adjusted according to the difference between the actual ambient temperature and the set temperature. Specifically, the greater the difference between the actual ambient temperature and the set temperature (indicating the greater the refrigeration demand), the greater the exhaust gas high temperature protection adjustment value and the greater the second value; the smaller the difference between the actual ambient temperature and the set temperature (indicating the smaller the refrigeration demand), the smaller the exhaust gas high temperature protection adjustment value and the smaller the second value. For example, the difference between the actual ambient temperature and the set temperature is 9°C, the exhaust gas high temperature protection adjustment value is 105°C, and the second value is 5°C (the second protection interval at this time is [105, 110)); the difference between the actual ambient temperature and the set temperature is 5°C, the exhaust gas high temperature protection adjustment value is 103°C, and the second value is 3°C (the second protection interval at this time is [103, 106)). This is because, when the exhaust gas temperature parameter is in the first protection interval of the exhaust gas temperature parameter, the compressor can be controlled to be frequency-reduced (i.e., the motor speed of the compressor is reduced) until the exhaust gas temperature parameter is adjusted to the second protection interval of the exhaust gas temperature parameter, and then the compressor can be controlled to be frequency-fixed (e.g., the motor speed of the compressor is unchanged), and the greater the refrigeration demand, the greater the working frequency of the compressor at this time to achieve frequency-fixed operation, and the smaller the refrigeration demand, the smaller the working frequency of the compressor at this time to achieve frequency-fixed operation. For example, when the exhaust gas temperature parameter drops into [105, 110), the motor speed of the compressor is reduced to 500 revolutions per minute, and the motor speed of the compressor can work at 500 revolutions per minute; when the exhaust gas temperature parameter drops into [103, 106), the motor speed of the compressor is reduced to 300 revolutions per minute, and the motor speed of the compressor can work at 300 revolutions per minute.

[0053] 3、The detection parameter is the suction pressure parameter, the first protection interval of the suction pressure parameter is determined according to the suction low pressure alarm value, the suction low pressure protection adjustment value and the third value, wherein the first protection interval of the suction pressure is greater than the suction low pressure alarm value and less than or equal to the suction low pressure protection adjustment value minus the third value (i.e. (suction low pressure alarm value, suction low pressure protection adjustment value minus third value]); the second protection interval of the suction pressure parameter is determined according to the suction low pressure protection adjustment value and the third value, wherein the second protection interval of the suction pressure is greater than the suction low pressure protection adjustment value minus the third value and less than or equal to the suction low pressure protection adjustment value (i.e. (suction low pressure protection adjustment value minus third value, suction low pressure protection adjustment value]). The difference between the suction low pressure protection adjustment value and the third value (i.e. suction low pressure protection adjustment value minus third value) is greater than the suction low pressure alarm value.

[0054] In an implementation, the suction low pressure protection adjustment value and the third value can be a default value set by a person, for example, the suction low pressure protection adjustment value is 7.5 bar and the third value is 0.5 bar, at this time, the first protection interval of the exhaust pressure parameter is (2.5, 7], and the second protection interval of the exhaust pressure parameter is (7, 7.5].

[0055] In another implementation, the suction low pressure protection adjustment value and the second value can be dynamically adjusted according to the difference between the actual ambient temperature and the set temperature. Specifically, the greater the difference between the actual ambient temperature and the set temperature (indicating the greater the refrigeration demand), the smaller the suction low pressure protection adjustment value and the second value; the smaller the difference between the actual ambient temperature and the set temperature (indicating the smaller the refrigeration demand), the greater the suction low pressure protection adjustment value and the second value. For example, when the difference between the actual ambient temperature and the set temperature is 9°C, the suction low pressure protection adjustment value is 7 bar, and the second value is 0.2 bar (at this time, the second protection interval is (6.8, 7]); when the difference between the actual ambient temperature and the set temperature is 5°C, the suction low pressure protection adjustment value is 7.5 bar, and the second value is 0.5 bar (at this time, the second protection interval is (7, 7.5]). This is because, when the suction pressure parameter is in the first protection interval of the suction pressure parameter, the compressor can be controlled to be frequency-reduced (i.e., the motor speed of the compressor is reduced) until the suction pressure parameter is adjusted to the second protection interval of the suction pressure parameter, and then the compressor can be frequency-fixed (e.g., the motor speed of the compressor is unchanged). When the refrigeration demand is greater, the compressor can be frequency-fixed at a larger working frequency at this time; when the refrigeration demand is smaller, the compressor can be frequency-fixed at a smaller working frequency at this time. For example, when the suction pressure parameter drops into (6.8, 7], the motor speed of the compressor is reduced to 400 revolutions per minute, and the motor speed of the compressor can work at 400 revolutions per minute; when the suction pressure parameter drops into (7, 7.5], the motor speed of the compressor is reduced to 300 revolutions per minute, and the motor speed of the compressor can work at 300 revolutions per minute.

[0056] 4、The detection parameter is the suction and exhaust pressure ratio, the first protection interval of the suction and exhaust pressure ratio is determined according to the suction and exhaust pressure ratio alarm value, the suction and exhaust pressure ratio protection adjustment value and the fourth value, wherein the first protection interval of the suction and exhaust pressure ratio is greater than the suction and exhaust pressure ratio alarm value and less than or equal to the suction and exhaust pressure ratio protection adjustment value + the fourth value (i.e. (the suction and exhaust pressure ratio alarm value, the suction and exhaust pressure ratio protection adjustment value - the fourth value]); the second protection interval of the suction and exhaust pressure ratio is determined according to the suction and exhaust pressure ratio protection adjustment value and the fourth value, wherein the second protection interval of the suction and exhaust pressure ratio is greater than the suction and exhaust pressure ratio protection adjustment value - the fourth value and less than the suction and exhaust pressure ratio protection adjustment value (i.e. (the suction and exhaust pressure ratio protection adjustment value - the fourth value, the suction and exhaust pressure ratio protection adjustment value)). The suction and exhaust pressure ratio alarm value is determined according to the lower limit value of the ideal compression ratio of the compressor, for example, if the ideal compression ratio of the compressor is [3, 10], the suction and exhaust pressure ratio alarm value can be 3. The difference between the suction and exhaust pressure ratio protection adjustment value and the fourth value (i.e. the suction and exhaust pressure ratio protection adjustment value - the fourth value) should be less than the suction and exhaust pressure ratio alarm value. The suction and exhaust pressure ratio protection adjustment value and the fourth value can be a default value set by a person, which can be set as needed, such as the suction and exhaust pressure ratio protection adjustment value.

[0057] In one embodiment, if the detection parameter is any one of the exhaust temperature parameter, the exhaust pressure parameter and the suction pressure parameter, the compressor is controlled according to the first control strategy for frequency conversion processing until the detection parameter is adjusted to the second protection interval, including:

[0058] The first control strategy indicates a first frequency reduction time interval and a first frequency reduction speed. The first frequency reduction speed is used to indicate a unit decrease of the working frequency of the compressor. For example, if the first frequency reduction speed is 1 Hz / 5 s, the first frequency reduction speed means that the working frequency of the compressor decreases by 1 Hz (unit of working frequency) every 5 seconds. It should be noted that the working frequency of the compressor is in a positive correlation with the motor speed of the compressor. The greater the working frequency of the compressor, the greater the motor speed of the compressor. The first frequency reduction time interval refers to the interval time of the frequency reduction processing of the compressor. According to the first frequency reduction time interval and the first frequency reduction speed, a first control instruction can be sent to the frequency converter in the space conditioning object. The first control instruction is used to control the frequency converter to adjust the working frequency of the compressor until the detection parameter is adjusted to the second protection interval. In the implementation process, the first control instruction can include the first frequency reduction time interval and the first frequency reduction speed. The frequency converter can reduce the working frequency of the compressor (that is, perform frequency reduction processing on the compressor) according to the first frequency reduction time interval and the first frequency reduction speed. For example, if the first frequency reduction speed is 1 Hz / 5 s and the first frequency reduction time interval is 1 minute, the frequency converter can perform frequency reduction processing on the working frequency of the compressor according to 1 Hz / 5 s in the first minute, then control the working frequency of the compressor to be in a stable state (including two cases that the working frequency of the compressor is unchanged or fluctuates in a small range (such as a preset range)) in the second minute, and perform frequency reduction processing on the working frequency of the compressor according to 1 Hz / 5 s in the third minute. In this way, the frequency reduction processing is performed on the working frequency of the compressor according to 1 Hz / 5 s until the detection parameter is adjusted to the second protection interval. Alternatively, the first control instruction can be sent to the frequency converter in the space conditioning object only according to the first frequency reduction speed. In this case, the frequency converter can reduce the working frequency of the compressor according to the first frequency reduction speed.

[0059] Therefore, the embodiment of the present application can trigger the failure warning mechanism of the compressor when the exhaust temperature parameter is too high, the exhaust pressure parameter is too high, and the suction pressure parameter is too low, reduce the working frequency of the compressor, reduce the exhaust temperature parameter and the exhaust pressure parameter, and increase the suction pressure parameter, so as to prevent the compressor from triggering a failure alarm (including exhaust high-temperature alarm, exhaust high-pressure alarm, and suction low-pressure alarm).

[0060] It should be noted that when the working frequency of the compressor gradually increases (and cannot be greater than the upper limit of the normal working frequency of the compressor), the compression efficiency also increases, and then the suction and exhaust pressure ratio also increases. In another embodiment, if the detection parameter is the suction and exhaust pressure ratio, the first control strategy is used to control the compressor to perform frequency adjustment processing until the detection parameter is adjusted to the second protection interval, including:

[0061] The first control strategy indicates a first frequency increasing time interval and a first frequency increasing speed. The first frequency increasing speed is used to indicate a unit increase of the working frequency of the compressor, for example, if the first frequency increasing speed is 1 Hz / 3 s, the first frequency increasing speed indicates that the working frequency of the compressor increases by 1 Hz every 3 seconds. The first frequency increasing time interval refers to the interval time of the frequency increasing process of the compressor. According to the first frequency increasing time interval and the first frequency increasing speed, a fourth control instruction can be sent to the frequency converter in the space conditioning object, and the fourth control instruction is used to control the frequency converter to adjust the working frequency of the compressor until the detection parameter is adjusted to the second protection interval of the detection parameter. In a specific implementation, the fourth control instruction can include the first frequency increasing time interval and the first frequency increasing speed, and the frequency converter can increase the working frequency of the compressor (i.e., perform the frequency increasing process on the compressor) according to the first frequency increasing time interval and the first frequency increasing speed. For example, if the first frequency increasing speed is 1 Hz / 3 s and the first frequency increasing time interval is 1 minute, the frequency converter can perform the frequency increasing process on the working frequency of the compressor according to 1 Hz / 3 s in the first minute, then control the working frequency of the compressor to be in a stable state (including two cases that the working frequency of the compressor is unchanged or fluctuates in a very small range (such as a preset range)) in the second minute, and perform the frequency increasing process on the working frequency of the compressor according to 1 Hz / 5 s in the third minute, and so on, until the detection parameter is adjusted to the second protection interval. Alternatively, the fourth control instruction can be sent to the frequency converter in the space conditioning object only according to the first frequency increasing speed, and the frequency converter can increase the working frequency of the compressor according to the first frequency increasing speed.

[0062] Therefore, the embodiment of the present application can trigger the failure warning mechanism of the compressor when the suction-discharge pressure ratio is too low, increase the working frequency of the compressor, and increase the suction-discharge pressure ratio to prevent the compressor from triggering a failure alarm (i.e., a compression ratio too low alarm).

[0063] In one implementation, if the detection parameter is adjusted to the third protection interval of the detection parameter in the case of performing the frequency adjustment process on the compressor by using the first control strategy, the second control strategy is used to control the frequency adjustment process of the compressor based on the target rotating speed of the compressor.

[0064] In the embodiments of the present application, the third protection interval of the exhaust pressure parameter is determined according to the exhaust high-pressure protection adjustment value and the first numerical value, and the third protection interval of the exhaust pressure parameter is greater than or equal to the exhaust high-pressure protection adjustment value minus the first numerical value and less than the exhaust high-pressure protection adjustment value (i.e., [exhaust high-pressure protection adjustment value minus first numerical value, exhaust high-pressure protection adjustment value]), for example, if the exhaust high-pressure protection adjustment value is 38 bar and the first numerical value is 1 bar, the third protection interval of the exhaust pressure parameter is [37, 38). The third protection interval of the exhaust temperature parameter is determined according to the exhaust high-temperature protection adjustment value and the second numerical value, wherein the third protection interval of the exhaust temperature parameter is greater than or equal to the exhaust high-temperature protection adjustment value minus the second numerical value and less than the exhaust high-temperature protection adjustment value (i.e., [exhaust high-temperature protection adjustment value minus second numerical value, exhaust high-temperature protection adjustment value]), for example, if the exhaust high-temperature protection adjustment value is 105℃ and the second numerical value is 5℃, the third protection interval of the exhaust temperature parameter is [100, 105). The third protection interval of the suction pressure parameter is determined according to the suction low-pressure protection adjustment value and the third numerical value, wherein the third protection interval of the suction pressure parameter is greater than the suction low-pressure protection adjustment value and less than or equal to the suction low-pressure protection adjustment value plus the third numerical value (i.e., (suction low-pressure protection adjustment value, suction low-pressure protection adjustment value + third numerical value]), for example, if the suction low-pressure protection adjustment value is 7.5 bar and the third numerical value is 0.5 bar, the third protection interval of the suction pressure parameter is (7.5, 8]. The third protection interval of the suction-exhaust pressure ratio is determined according to the suction-exhaust pressure ratio protection adjustment value and the fourth numerical value, and the third protection interval of the suction-exhaust pressure ratio is greater than the suction-exhaust pressure ratio protection adjustment value and less than or equal to the suction-exhaust pressure ratio protection adjustment value plus the fourth numerical value (i.e., (suction-exhaust pressure ratio protection adjustment value, suction-exhaust pressure ratio protection adjustment value + fourth numerical value]).

[0065] In one embodiment, if the relationship between the detection parameter and the protection exit value within the preset time length meets the first condition when the compressor is frequency-controlled by using the first control strategy, the compressor is controlled to perform frequency control according to a system default control strategy. The preset time length is a positive integer time length value, which can be set artificially, such as 5 seconds. The system default control strategy refers to that the controller controls the compressor to perform frequency control according to the target speed of the compressor, so that the actual speed of the compressor is adjusted to the target speed of the compressor.

[0066] In the embodiments of the present application, the protection exit value of the exhaust pressure parameter is determined according to the exhaust high pressure protection adjustment value and the first value, wherein the protection exit value of the exhaust pressure parameter is the difference between the exhaust high pressure protection adjustment value and the first value (exhaust high pressure protection adjustment value-first value), for example, the exhaust high pressure protection adjustment value is 38 bar, and the first value is 1 bar, so the protection exit value of the exhaust pressure parameter is 37 bar; when the exhaust pressure parameter continuously decreases to less than the protection exit value of the exhaust pressure parameter within the preset time length, it is determined that the relationship between the detection parameter and the protection exit value within the preset time length meets the first condition. The protection exit value of the exhaust temperature parameter is determined according to the exhaust high temperature protection adjustment value and the second value, wherein the protection exit value of the exhaust temperature parameter is the difference between the exhaust high temperature protection adjustment value and the second value (exhaust high temperature protection adjustment value-second value), for example, the exhaust high temperature protection adjustment value is 105 DEG C, and the second value is 5 DEG C, so the protection exit value of the exhaust temperature parameter is 100 DEG C; when the exhaust temperature parameter continuously decreases to less than the protection exit value of the exhaust temperature parameter within the preset time length, it is determined that the relationship between the detection parameter and the protection exit value within the preset time length meets the first condition. The protection exit value of the suction pressure parameter is determined according to the suction low pressure protection adjustment value and the third value, wherein the protection exit value of the suction pressure parameter is the sum of the suction low pressure protection adjustment value and the third value (suction low pressure protection adjustment value+third value), for example, the suction low pressure protection adjustment value is 7.5 bar, and the third value is 0.5 bar, so the protection exit value of the suction pressure parameter is 8 bar; when the suction pressure parameter continuously increases to greater than the protection exit value of the suction pressure parameter within the preset time length, it is determined that the relationship between the detection parameter and the protection exit value within the preset time length meets the first condition. The protection exit value of the suction and exhaust pressure ratio is determined according to the suction and exhaust pressure ratio protection adjustment value and the fourth value, wherein the protection exit value of the suction and exhaust pressure ratio is the sum of the suction and exhaust pressure ratio protection adjustment value and the fourth value (suction and exhaust pressure ratio protection adjustment value+fourth value); when the suction and exhaust pressure ratio continuously increases to greater than the protection exit value of the suction and exhaust pressure ratio within the preset time length, it is determined that the relationship between the detection parameter and the protection exit value within the preset time length meets the first condition.

[0067] S303, if the detection parameter is in the second protection interval, a second control strategy for controlling the compressor is determined, and the compressor is controlled to perform frequency modulation processing based on the target speed of the compressor according to the second control strategy.

[0068] In one embodiment, if the detection parameter is any one of the exhaust temperature parameter, the exhaust pressure parameter, and the suction pressure parameter, the compressor is controlled to perform frequency modulation processing based on the target speed of the compressor according to the second control strategy, including any one or both of the following steps:

[0069] When the target rotating speed of the compressor is greater than or equal to the actual rotating speed of the compressor, it indicates that the compressor has a frequency increasing demand or a frequency constant demand, but if the compressor is frequency increased, it is likely to cause the exhaust pressure parameter to reach the exhaust high pressure alarm value, or the exhaust temperature parameter to reach the exhaust high temperature alarm value, or the suction pressure parameter to reach the suction low pressure alarm value, therefore, at this time, a second control instruction is sent to the frequency converter in the space conditioning object, the second control instruction is used to control the frequency converter to control the working frequency of the compressor, so that the working frequency of the compressor is in a stable state, the working frequency of the compressor in the stable state can include two cases that the working frequency of the compressor is unchanged, and the working frequency of the compressor fluctuates within a very small range (such as a preset range [-1, 1]). Wherein, the target rotating speed of the compressor is mainly determined by the refrigeration demand, and the refrigeration demand is affected by the indoor temperature, the outdoor temperature and the set temperature, for example, when the difference between the indoor temperature and the set temperature is large, it indicates that the refrigeration demand is large, and the target rotating speed of the compressor is large. At this time, the working frequency of the compressor can be controlled to be in a stable state, so as to achieve the dynamic balance between the working frequency of the compressor and the compressor failure alarm.

[0070] When the target rotating speed of the compressor is less than the actual rotating speed of the compressor, it indicates that the compressor has a frequency decreasing demand, and the second frequency decreasing time interval and the second frequency decreasing speed indicated by the second control strategy are determined. Wherein, the second frequency decreasing speed is used to indicate the unit decrease amount of the working frequency of the compressor, for example, if the second frequency decreasing speed is 1hz / 5s, the second frequency decreasing speed indicates that every 5 seconds, the working frequency of the compressor decreases by 1hz (unit of working frequency). The second frequency decreasing time interval refers to the interval time of frequency decreasing treatment of the compressor. According to the second frequency decreasing time interval and the second frequency decreasing speed, a third control instruction can be sent to the frequency converter, the third control instruction is used to control the frequency converter to adjust the working frequency of the compressor, until the actual rotating speed of the compressor is adjusted to the target rotating speed of the compressor. In specific implementation, the third control instruction can include the second frequency decreasing time interval and the second frequency decreasing speed, and the frequency converter can decrease the working frequency of the compressor (i.e. frequency decreasing treatment of the compressor) according to the second frequency decreasing time interval and the second frequency decreasing speed. Alternatively, the third control instruction can be sent to the frequency converter in the space conditioning object only according to the second frequency decreasing speed, at this time, the frequency converter can decrease the working frequency of the compressor according to the second frequency decreasing speed.

[0071] In another embodiment, if the detection parameter is the suction and exhaust pressure ratio, the compressor is controlled to be frequency adjusted according to the target rotating speed of the compressor based on the second control strategy, including any one or both of the following steps:

[0072] When the target rotating speed of the compressor is less than or equal to the actual rotating speed of the compressor, it indicates that the compressor has a frequency reduction demand or a constant frequency demand, but if the frequency reduction process is performed on the compressor, the suction and exhaust pressure ratio may reach the suction and exhaust pressure ratio alarm value, and therefore the fifth control instruction is sent to the frequency converter in the space conditioning object, and the fifth control instruction is used to control the frequency converter to control the operating frequency of the compressor, so that the operating frequency of the compressor is in a stable state, which can include two cases that the operating frequency of the compressor is unchanged and the operating frequency of the compressor fluctuates within a very small range (such as a preset range [-1, 1]). The target rotating speed of the compressor is mainly determined by the refrigeration demand, which is affected by the indoor temperature, the outdoor temperature and the set temperature. For example, when the difference between the indoor temperature and the set temperature is large, it indicates that the refrigeration demand is large, and the target rotating speed of the compressor is large. At this time, the operating frequency of the compressor can be controlled to be in a stable state, so as to achieve a dynamic balance between the operating frequency of the compressor and the compressor failure alarm.

[0073] When the target rotating speed of the compressor is greater than the actual rotating speed of the compressor, it indicates that the compressor has a frequency increase demand or a constant frequency demand, and the second frequency increase time interval and the second frequency increase speed can be determined according to the second control strategy, and the sixth control instruction is sent to the frequency converter according to the second frequency increase time interval and the second frequency increase speed, and the sixth control instruction is used to control the frequency converter to adjust the operating frequency of the compressor until the actual rotating speed of the compressor is adjusted to the target rotating speed of the compressor. The second frequency increase speed is used to indicate the unit increase of the operating frequency of the compressor, for example, if the second frequency increase speed is 1 hz / 3 s, the second frequency increase speed indicates that every 3 seconds, the operating frequency of the compressor increases by 1 hz. The second frequency increase time interval refers to the interval time of the frequency increase process of the compressor. According to the second frequency increase time interval and the second frequency increase speed, the sixth control instruction is sent to the frequency converter in the space conditioning object, and the sixth control instruction is used to control the frequency converter to adjust the operating frequency of the compressor until the detection parameter is adjusted to the second protection interval of the detection parameter. In specific implementation, the sixth control instruction can include the second frequency increase time interval and the second frequency increase speed, and the frequency converter can increase the operating frequency of the compressor (i.e., perform the frequency increase process on the compressor) according to the second frequency increase time interval and the second frequency increase speed. Alternatively, the sixth control instruction can be sent to the frequency converter in the space conditioning object only according to the second frequency increase speed, and the frequency converter can increase the operating frequency of the compressor according to the second frequency increase speed.

[0074] In one embodiment, if the detection parameter is adjusted to the third protection interval of the detection parameter in the case of performing the frequency adjustment process on the compressor by using the second control strategy, the frequency adjustment process is performed on the compressor based on the target rotating speed of the compressor according to the second control strategy.

[0075] In one embodiment, if the relationship between the detection parameter and the protection exit value within the preset time length meets the first condition in the case that the compressor is frequency-regulated by using the second control strategy, the compressor is controlled to be frequency-regulated according to the system default control strategy. The preset time length is a positive integer time length value, which can be set artificially, for example, 5 seconds. The system default control strategy means that the controller controls the compressor to be frequency-regulated according to the target rotating speed of the compressor, so that the actual rotating speed of the compressor is adjusted to the target rotating speed of the compressor.

[0076] In the embodiments of the present application, the protection exit value of the exhaust pressure parameter is the difference between the exhaust high pressure protection adjustment value and the first value (exhaust high pressure protection adjustment value-first value), and when the exhaust pressure parameter is continuously less than the protection exit value of the exhaust pressure parameter within the preset time length, it is determined that the relationship between the detection parameter and the protection exit value within the preset time length meets the first condition. The protection exit value of the exhaust temperature parameter is the difference between the exhaust high temperature protection adjustment value and the second value (exhaust high temperature protection adjustment value-second value), and when the exhaust temperature parameter is continuously less than the protection exit value of the exhaust temperature parameter within the preset time length, it is determined that the relationship between the detection parameter and the protection exit value within the preset time length meets the first condition. The protection exit value of the suction pressure parameter is the sum of the suction low pressure protection adjustment value and the third value (suction low pressure protection adjustment value+third value), and when the suction pressure parameter is continuously greater than the protection exit value of the suction pressure parameter within the preset time length, it is determined that the relationship between the detection parameter and the protection exit value within the preset time length meets the first condition. The protection exit value of the suction-exhaust pressure ratio is the sum of the suction-exhaust pressure ratio protection adjustment value and the fourth value (suction-exhaust pressure ratio protection adjustment value+fourth value), and when the suction-exhaust pressure ratio is continuously greater than the protection exit value of the suction-exhaust pressure ratio within the preset time length, it is determined that the relationship between the detection parameter and the protection exit value within the preset time length meets the first condition.

[0077] In one embodiment, when the detection parameter is in the first protection interval or in the second protection interval, the pre-warning information about the compressor can be displayed (for example, on the display screen of the space conditioning object), so as to reserve enough time for the maintenance personnel to troubleshoot whether the compressor has a problem. For example, the exhaust pressure being too high is usually caused by the increase of the outer ring temperature (the ambient temperature of the external unit (also referred to as the condenser) in the space conditioning object), the failure of the exhaust fan, the dirt blocking of the condenser, etc. (i.e., when the condenser side does not work enough), so the problem of insufficient work of the condenser can be solved.

[0078] Please refer to Figure 4a , Figure 4a is an example schematic diagram of a management method of a space conditioning object provided by the embodiments of the present application in combination with the exhaust pressure parameter; for example, Figure 4aAs shown, when the exhaust pressure parameter PI is greater than or equal to 38 bar and less than 41.5 bar, the exhaust high pressure protection regulation is entered; specifically, when the exhaust pressure parameter PI is greater than or equal to 39 bar and less than 41.5 bar, the compressor is frequency-regulated according to the first control strategy; when the exhaust pressure parameter is greater than or equal to 38 bar and less than 39 bar, the compressor is frequency-regulated according to the second control strategy based on the target speed of the compressor; when the exhaust pressure parameter is adjusted to [37, 38), the compressor is frequency-regulated according to the second control strategy based on the target speed of the compressor; and when the exhaust pressure parameter is less than 37 bar for a preset time (for example, 10 seconds), the exhaust high pressure protection regulation is exited. In addition, when the exhaust pressure parameter is greater than or equal to 41.5 bar, the exhaust high pressure alarm of the compressor is triggered, causing the compressor to shut down. The exhaust temperature parameter is similar to the exhaust pressure parameter and will not be described again.

[0079] Please refer to Figure 4b , Figure 4b is an example schematic diagram of a management method of a space conditioning object provided by the embodiment of the present application in combination with the suction pressure parameter; as Figure 4b shown, when the suction pressure parameter XI is greater than 2.5 bar and less than or equal to 7.5 bar, the suction low pressure protection regulation is entered; specifically, when the suction pressure parameter is greater than 2.5 bar and less than or equal to 7 bar, the compressor is frequency-regulated according to the first control strategy; when the suction pressure parameter PI is greater than 7 bar and less than or equal to 7.5 bar, the compressor is frequency-regulated according to the second control strategy based on the target speed of the compressor; when the suction pressure parameter is adjusted to (7.5, 8], the compressor is frequency-regulated according to the second control strategy based on the target speed of the compressor; and when the suction pressure parameter is greater than 8 bar for a preset time (for example, 10 seconds), the suction low pressure protection regulation is exited. In addition, when the suction pressure parameter is less than or equal to 2.5 bar, the suction low pressure alarm of the compressor is triggered, causing the compressor to shut down. The suction pressure parameter is similar to the suction / exhaust pressure ratio and will not be described again.

[0080] In a feasible implementation, multiple compressors can be configured in the space conditioning object, and after one compressor is shut down due to a fault, the remaining compressors can still normally output cold energy.

[0081] In a feasible implementation, a fluorine pump system (a kind of refrigeration system) can be configured in the space conditioning object, and after the compressor is shut down due to a fault, the fluorine pump system can be started in time to realize cold energy output.

[0082] Therefore, the embodiment of the application can protect and adjust the motor speed of the compressor in advance when the detection parameter abnormally changes (increases or decreases), and return to the general demand adjustment when the detection parameter is in the controllable range, so as to avoid the increase of the supply air temperature caused by the stop of the compressor due to failure, reduce the start-stop frequency of the compressor, prolong the service life of the compressor, realize continuous cold output, and improve the operation reliability of the space conditioning object.

[0083] The electronic expansion valve can be included in the space conditioning object and can be used to accurately adjust the flow rate of the refrigerant in the refrigeration cycle to adapt to the flow rate change requirement of the compressor. The electronic expansion valve has a certain opening range, and is usually 100-500 steps in normal use. The opening of the electronic expansion valve directly affects the refrigeration performance of the space conditioning object. If the opening of the electronic expansion valve is too small, the refrigerant flow rate cannot be adjusted enough, so that the space conditioning object cannot meet the refrigeration load requirement, thereby reducing the refrigeration efficiency. If the opening of the electronic expansion valve is too large, the refrigerant flow rate changes too fast, so that the space conditioning object cannot maintain stable refrigeration effect.

[0084] The suction superheat degree refers to the phenomenon that the temperature of the suction gas exceeds the saturation temperature during the suction process of the compressor. Specifically, the suction superheat degree = suction temperature - saturation temperature corresponding to suction pressure; wherein the suction temperature parameter refers to the temperature of the refrigerant gas at the running inlet of the compressor, which can be detected by arranging a temperature sensor at the running inlet of the compressor; and the saturation temperature corresponding to the suction pressure refers to the temperature when the substance changes from liquid to gas under the condition that the suction pressure is constant. When the suction of the compressor refrigerant gas is insufficient, it is likely to cause the problem of excessive suction superheat degree.

[0085] The subcooling degree is used to describe the difference between the actual temperature of the refrigerant at the outlet of the condenser and the saturation temperature corresponding to the actual pressure. When the subcooling degree is too low, it may be caused by insufficient refrigerant in the space conditioning object.

[0086] In one embodiment, if the opening of the electronic expansion valve is greater than the first threshold value for a preset time period, the suction superheat degree is greater than the upper limit value of the superheat degree for a preset time period, and the subcooling degree is less than or equal to the lower limit value of the subcooling degree for a preset time period, the first warning information is displayed. If the opening of the electronic expansion valve is less than or equal to the second threshold value for a preset time period, the suction superheat degree is less than or equal to the lower limit value of the superheat degree for a preset time period, and the subcooling degree is greater than the upper limit value of the subcooling degree for a preset time period, the first warning information is removed (i.e., the first warning information is not displayed).

[0087] The first early warning information is used to prompt that the refrigerant in the compressor is too little, and can be used to remind the operation and maintenance personnel to add refrigerant to the refrigeration cycle. The first threshold value and the second threshold value are determined according to the rated opening degree of the electronic expansion valve, and the first threshold value is greater than the second threshold value. The rated opening degree of the electronic expansion valve can be determined according to the upper limit value of the opening degree range of the electronic expansion valve (for example, the opening degree range of the electronic expansion valve is generally 100-500 steps, and the rated opening degree of the electronic expansion valve can be 500 steps). Specifically, the first threshold value can be the rated opening degree of the electronic expansion valve × M%, and the second threshold value can be the rated opening degree of the electronic expansion valve × N%, M and N are positive integers, and M is greater than N, and M is less than or equal to 100; for example, the rated opening degree of the electronic expansion valve can be 500 steps, the first threshold value is 500 × 90%, and the second threshold value is 500 × 70%. The preset time length can be obtained by human setting, for example, the preset time length can be 5 minutes. The upper limit value of the suction superheat degree and the lower limit value of the suction superheat degree can be determined according to the normal range of the suction superheat degree, for example, the normal range of the suction superheat degree is 5-10℃, and 12℃ can be determined as the upper limit value of the suction superheat degree, and 8℃ can be determined as the lower limit value of the suction superheat degree. In a feasible implementation manner, the difference between the suction superheat degree set value and the fifth value can be determined as the lower limit value of the suction superheat degree, and the sum of the suction superheat degree set value and the fifth value can be determined as the upper limit value of the suction superheat degree, wherein the suction superheat degree set value is a set value for evaluating the suction superheat degree (for example, 8℃), and the fifth value is a preset value (for example, 3℃). The upper limit value of the supercooling degree and the lower limit value of the supercooling degree can be determined according to the normal range of the supercooling degree, for example, the normal range of the supercooling degree is 5-12℃, 3℃ can be determined as the lower limit value of the supercooling degree, and 6℃ can be determined as the upper limit value of the supercooling degree.

[0088] Therefore, according to the embodiments of the present application, whether the refrigerant in the compressor (or the refrigeration cycle) is too little can be evaluated from the three dimensions of the opening degree of the electronic expansion valve, the suction superheat degree and the supercooling degree, so as to early warn the refrigerant too little in the refrigeration cycle, so as to avoid insufficient cold output and reduce the start-stop times of the compressor.

[0089] Please refer to Figure 5 , Figure 5 is another flowchart of a space conditioning object management method provided by the embodiments of the present application. The space conditioning object management method includes the following steps S501-S502:

[0090] S501, if the health degree parameter of the fan in the space conditioning object is greater than the early warning value of the health degree parameter within a preset time length, a second early warning information is displayed; wherein the second early warning information is used to prompt that the fan has a risk of failure, and the health degree parameter includes any one of the fan vibration value and the fan current value.

[0091] The space conditioning object includes a fan (such asFigure 1 The health degree parameter of the fan is a fan state value fed back by the fan in real time, such as any one of a fan vibration value, a fan current value. The fan vibration value can be detected by a vibration detection instrument, and the fan current value can be detected by a current sensor. The early warning value of the fan vibration value can be determined according to a normal range of the fan vibration value, such as that the fan vibration value is generally not more than 7.1 mm / s (a unit of speed), and the early warning value of the fan vibration value can be determined as 7.1 mm / s. The early warning value of the fan current value can be determined according to a normal range of the fan current value, such as that the fan current value is generally not more than 7.5 A (a unit of current), and the early warning value of the fan current value can be determined as 7.5 A. The preset time length can be artificially set, such as 5 minutes.

[0092] In one embodiment, the second early warning information is displayed when the health degree parameter of the fan in the space conditioning object continuously exceeds the early warning value of the health degree parameter within the preset time length, and the second early warning information is used to prompt that the fan has a risk of failure. Maintenance personnel can individually shut down the fan with the early warning for inspection and maintenance without affecting the operation of the whole machine.

[0093] S502, if the health degree parameter of the fan in the space conditioning object continuously is less than or equal to the recovery value of the health degree parameter within the preset time length, the second early warning information is removed.

[0094] The recovery value of the health degree parameter can be determined according to a normal range of the health degree parameter, such as that the recovery value of the fan vibration value is 6 mm / s, and the recovery value of the fan current value is 7 A.

[0095] In one embodiment, if the health degree parameter of the fan in the space conditioning object continuously is less than or equal to the recovery value of the health degree parameter within the preset time length, the second early warning information is removed, that is, the display of the second early warning information is cancelled.

[0096] Therefore, the embodiments of the present application can judge the health degree according to the device parameter of the fan, and issue a prompt early warning to remind the operation and maintenance personnel to check or maintain, prevent failure in advance, do not affect the normal logic operation of the device, and can reduce the cost of replacing the device.

[0097] Please refer to Figure 6 , Figure 6 is a flow diagram of another space conditioning object management method provided by the embodiments of the present application. The space conditioning object management method comprises the following steps S601-S602:

[0098] S601, if the outdoor wet film efficiency of the wet film in the space conditioning object continuously is less than the wet film efficiency early warning value within the preset time length, the fourth early warning information is displayed, and the fourth early warning information is used to prompt that the efficiency of the wet film is too low.

[0099] The space conditioning object is a device that can adjust the humidity in the space, and the space conditioning object can include a wet film. The wet film can include any one of an organic wet film, an inorganic wet film, an aluminum alloy mesh wet film, a stainless steel perforated wet film, and a ceramic wet film, and the wet film can be used to humidify dry air.

[0100] It should be noted that the outdoor wet film efficiency of the wet film = (outdoor inlet dry bulb temperature - condenser inlet temperature) / (outdoor inlet dry bulb temperature - outdoor inlet wet bulb temperature), wherein the dry bulb temperature refers to the air temperature measured by a thermometer, the wet bulb temperature refers to the lowest temperature that the current environment can reach only by evaporating water, the outdoor inlet dry bulb temperature refers to the dry bulb temperature in the outdoor environment, the outdoor inlet wet bulb temperature refers to the wet bulb temperature in the outdoor environment, and the condenser inlet temperature refers to the temperature of the refrigerant gas at the inlet of the condenser.

[0101] When the efficiency of the wet film is too low, it indicates that the efficiency of the wet film is low and cannot well humidify dry air. Therefore, in an embodiment, if the outdoor wet film efficiency of the wet film in the space conditioning object continuously is less than the wet film efficiency warning value within a preset time length, fourth warning information is displayed, and the fourth warning information is used to prompt that the efficiency of the wet film is too low. The preset time length can be set artificially, such as 5 seconds, and the wet film efficiency warning value can be determined according to the lower limit value of the normal range of the outdoor wet film efficiency, such as the wet film efficiency warning value being 0.2. The operation and maintenance personnel can detect whether the wet film is too dirty, whether the spray pipeline is blocked, and whether the water pump (such as the water pump used by the spray system) is working normally in advance through the fourth warning information.

[0102] S602, if the outdoor wet film efficiency of the wet film continuously is greater than or equal to the wet film efficiency recovery value within a preset time length, the fourth warning information is removed.

[0103] In an embodiment, if the outdoor wet film efficiency of the wet film in the space conditioning object continuously is greater than or equal to the wet film efficiency recovery value within a preset time length, the fourth warning information is removed, that is, the display of the fourth warning information is cancelled. The wet film efficiency recovery value can be determined according to the normal range of the outdoor wet film efficiency, such as the wet film efficiency recovery value being 0.3 by default.

[0104] The space conditioning object can include a differential pressure switch, which can be used to measure the difference (i.e., differential pressure) between the pressure on the air inlet side and the air outlet side of the wet membrane. When the differential pressure between the two sides of the wet membrane is greater than or equal to a preset differential pressure, the differential pressure switch is closed, and when the differential pressure between the two sides of the wet membrane is less than the preset differential pressure, the differential pressure switch is opened. For example, two pressure sensors can be respectively arranged on the air inlet side and the air outlet side of the wet membrane, and both of the pressure sensors are electrically connected to the differential pressure switch to measure the differential pressure between the air inlet side and the air outlet side of the wet membrane. In a possible implementation, when the differential pressure switch is in the closed state, it indicates that the differential pressure between the air inlet side and the air outlet side of the wet membrane is too large, and a third warning information can be displayed to prompt that the wet membrane is at risk of being blocked. The operator can clean the wet membrane according to the third warning information before the wet membrane fails to function. When the differential pressure switch on the outdoor side of the wet membrane is in the open state, the third warning information is removed, i.e., the third warning information is no longer displayed.

[0105] Therefore, the embodiments of the present application can determine the health degree of the wet membrane according to the device parameters of the wet membrane, and issue a prompt warning to remind the operator to check or maintain, so that the wet membrane can be processed before it fails.

[0106] The management scheme of the space conditioning object provided by the embodiments of the present application further provides a fault alarm mechanism, which is described by taking a target device in the space conditioning object (any device in the space conditioning object) as an example. In one embodiment, if a target device in the space conditioning object has a fault event, alarm information for the target device is generated; for example, if the target device is a pressure sensor for measuring the suction pressure (referred to as a suction pressure sensor), the alarm information of the target device can be used to indicate that the suction pressure sensor has a fault event.

[0107] In addition, the associated object of the target device needs to be determined. In an implementation, the associated object of the target device can be another device associated with the target device, which can cause the target device to send a derived alarm (a secondary alarm event differentiated from a root alarm event) when a fault event of the another device occurs. Specifically, the associated object of the target device can be another device capable of controlling the target device, for example, when the target device is a slave controller in a master-slave controller, the associated object of the target device is a master controller in the master-slave controller. When a fault event of the associated object of the target device is detected, alarm information of the target device is processed according to an alarm convergence strategy, and the alarm convergence strategy is used to indicate that alarm information corresponding to the associated object of the target device is shielded. For example, when a communication fault of the master-slave controller occurs, a sensor fault alarm or a device fault alarm of the slave controller will also occur at the same time, and at this time, the sensor fault alarm or the device fault alarm of the slave controller needs to be converged to facilitate an on-site operation and maintenance personnel to check and reset the main cause (the communication fault of the master-slave controller). It should be noted that if a fault event of the target device occurs before a fault alarm of the associated object of the target device occurs, alarm information of the target device will be normally displayed, and if a fault event of the target device occurs after a fault alarm of the associated object of the target device occurs, the alarm information of the target device will be shielded.

[0108] In another implementation, the associated object of the target device is a fault event dependent on the target device (that is, a fault event evaluated by a parameter detected by the target device), and at this time, if a fault event of the associated object is detected, alarm information of the target device is processed according to an alarm convergence strategy, and the alarm convergence strategy is used to indicate that the fault event dependent on the target device is shielded, and the alarm information of the target device is displayed. For example, when a fault event of an air suction pressure sensor occurs, alarm information about the air suction pressure sensor (which can be used to indicate that a fault event of the air suction pressure sensor occurs) is displayed, and an air suction low pressure alarm is shielded. It should be noted that if a fault event dependent on the target device occurs before a fault event of the target device occurs, the fault event dependent on the target device will normally send a fault alarm, and if a fault event dependent on the target device occurs after a fault event of the target device occurs, the fault event dependent on the target device will be shielded.

[0109] As can be seen, the fault alarm mechanism provided in the embodiments of the present application only reports the main cause of a fault alarm, and derived alarms generated thereby are converged, so that a maintenance personnel can find a root cause of a fault in time to maintain a space conditioning object, and the reliability and stability of the space conditioning object are improved.
