Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
The control method of the refrigerating system provided by the embodiment of the application can be applied to an application environment shown in fig. 1. Wherein the refrigeration system comprises a plurality of refrigeration units 10, the plurality of refrigeration units 10 comprising a master refrigeration unit 11 and at least one slave refrigeration unit 12. The master refrigeration unit 11 communicates with each slave refrigeration unit 12 via a network. The refrigeration unit 10 may be, but is not limited to, various devices having cooling and/or heating properties such as an air conditioner, a refrigerator, a warmer, a radiator, a freezer, etc.
In one embodiment, as shown in fig. 2, a control method of a refrigeration system is provided, and the control method is described by taking as an example a main refrigeration unit 11 applied to the refrigeration system shown in fig. 1, and the control method includes the following steps S202 to S206.
S202: the current load of each refrigeration unit 10 in operation in the refrigeration system is obtained.
In use, the main refrigeration unit 11 obtains the current load of each refrigeration unit 10 in operation in the refrigeration system. For example, the main refrigeration unit 11 may obtain the operation state of each refrigeration unit 10 in the refrigeration system, and determine the refrigeration unit 10 in the operation state according to the operation state of each refrigeration unit 10. The operating state is used to indicate an operating condition of the refrigeration unit 10, including, but not limited to, the refrigeration unit 10 being in an operating state, the refrigeration unit 10 being in an idle state or a shutdown state, the refrigeration unit 10 being in a fault state. The operating state is understood to be an operating state providing a cooling function or a cooling function. It will be appreciated that if the main refrigeration unit 11 is currently in a cooling or heating operation, the main refrigeration unit 11 obtains the current load of each of the sub-refrigeration units 12 in the operation as well as the current load of itself.
S204: the average load of all the refrigeration units 10 in operation is determined based on the current load of each refrigeration unit 10 in operation.
In use, the main refrigeration unit 11 may determine the average load of all refrigeration units 10 in operation based on the current load of each refrigeration unit 10 in operation. For example, the main refrigeration unit 11 may determine the current total load of the refrigeration system based on the current load of each refrigeration unit 10 in the operating state, and then determine the average load of all refrigeration units 10 in the operating state based on the current total load of the refrigeration system and the number of refrigeration units 10 in the operating state. For example, if the total load of the refrigeration system is S and there are N refrigeration units 10 in operation in the refrigeration system, the average load q=s/N.
S206: the average load is sent to each slave refrigeration unit 12 in the operational state to indicate that each slave refrigeration unit 12 in the operational state is operating according to the average load. Wherein the slave refrigeration unit 12 is one of the plurality of refrigeration units 10.
In use, the master refrigeration unit 11 sends an average load to each slave refrigeration unit 12 in operation, thereby indicating that each slave refrigeration unit 12 in operation is operating according to the average load. It will be appreciated that if the main refrigeration unit 11 is also currently in operation, then the main refrigeration unit 11 is also operated according to the average load.
According to the control method of the refrigerating system, the main refrigerating unit 11 obtains the current load of each refrigerating unit 10 in the running state in the refrigerating system, determines the average load of all the refrigerating units 10 in the running state according to the current load of each refrigerating unit 10 in the running state, and sends the average load to each slave refrigerating unit 12 in the running state to indicate that each slave refrigerating unit 12 in the running state runs according to the average load, therefore, each refrigerating unit 10 in the running state in the refrigerating system can run according to the average load, the load balance performance of the refrigerating system is improved, part of the refrigerating units 10 are prevented from running at high load and part of the refrigerating units 10 run at low load, the load balance performance of each refrigerating unit 10 in the refrigerating system is improved, the problems of high loss and high energy consumption of the refrigerating units 10 due to uneven load are solved, the service life of each refrigerating unit 10 is prolonged, and each refrigerating unit 10 can be controlled according to the average load only by determining the average load by one refrigerating unit 10 in the refrigerating system, so that the whole control flow is simple and efficient, and the whole energy efficiency of the system is improved.
In one embodiment, the control method of the refrigeration system may further include: and determining a load variation parameter of the refrigeration system according to the current load of each refrigeration unit 10 in the running state. Based on this, the step S206 described above, which transmits the average load to each slave refrigeration unit 12 in the operating state, may include: and a step of transmitting an average load to each slave refrigeration unit 12 in an operating state when the load variation parameter satisfies a preset condition.
In application, after the main refrigerating unit 11 obtains the current load of each refrigerating unit 10 in the running state, the load variation parameter of the refrigerating system can be determined according to the current load of each refrigerating unit 10, and when the load variation parameter meets the preset condition, the average load is determined according to the current load of each refrigerating unit 10, and the average load is sent to each slave refrigerating unit 12 in the running state, so as to instruct each slave refrigerating unit 12 in the running state to run according to the average load.
The load change parameter is used for representing the current load change condition of the refrigeration system. The magnitude of the load change parameter represents the current load change degree of the refrigerating system. Specifically, the larger the load change parameter, the larger the current load change of the refrigeration system; the smaller the load change parameter, the smaller the current load change of the refrigeration system. The preset condition is preset and is used for measuring the current load change degree of the refrigerating system. If the load variation parameter of the refrigeration system meets the preset condition, it indicates that the current load variation degree of the refrigeration system is smaller, and the refrigeration system is in a relatively stable state, in this case, the refrigeration system can be balanced load-adjusted, that is, the master refrigeration unit 11 sends an average load to each slave refrigeration unit 12 in the running state, so that each slave refrigeration unit 12 in the running state is adjusted from the current load to the average load. If the load change parameter of the refrigeration system does not meet the preset condition, the current load change degree of the refrigeration system is larger, and the refrigeration system is in a relatively unstable state, and in this case, the balance load adjustment can be performed after the load change parameter of the refrigeration system meets the preset condition.
In an exemplary case where the main refrigeration unit 11 determines that the load variation parameter of the refrigeration system does not meet the preset condition, each refrigeration unit 10 in the running state may respectively obtain the current temperature of each refrigeration circuit, and correspondingly adjust each current load according to the current temperature until the load variation parameter of the refrigeration system meets the preset condition, so that the refrigeration system quickly approaches to a stable state, so as to perform load balancing adjustment on the refrigeration system. Illustratively, the refrigeration circuit of each refrigeration unit 10 is provided with a temperature detection assembly, and each refrigeration unit 10 may obtain the current temperature of the respective refrigeration circuit through the respective corresponding temperature detection assembly.
According to the control method of the refrigerating system, the main refrigerating unit 11 determines the load change parameters of the refrigerating system according to the current load of each refrigerating unit 10 in the running state, and sends average load to each slave refrigerating unit 12 in the running state under the condition that the load change parameters meet the preset conditions, namely, the current load change degree of the refrigerating system is measured through the load change parameters, whether the refrigerating system is in a stable state is determined by combining the preset conditions, and the refrigerating system is subjected to load balance adjustment under the relatively stable state, so that the stability and the reliability of the refrigerating system are improved.
In one embodiment, the load variation parameter of the refrigeration system includes a total load variation parameter of all refrigeration units 10 in an operating state. In use, the main refrigeration unit 11 may determine the total load variation parameter of all refrigeration units 10 in operation based on the current load of each refrigeration unit 10 in operation. The total load variation parameter is used to represent the overall variation of all the refrigeration units 10 in the running state in the refrigeration system, and in short, the total load variation parameter represents the overall load variation of the refrigeration system. The magnitude of the total load change parameter represents the load change degree of the whole refrigerating system. Specifically, the greater the total load variation parameter, the greater the load variation degree of the refrigeration system as a whole; the smaller the total load variation parameter, the smaller the load variation degree of the whole refrigeration system.
Based on the above, the step of transmitting the average load to each slave refrigeration unit 12 in the operation state, that is, in the case where the load variation parameter satisfies the preset condition, may include: and a step of transmitting an average load to each slave refrigeration unit 12 in an operating state, in a case where the total load variation parameter is smaller than the first load threshold and the first holding time of the total load variation parameter smaller than the first load threshold is greater than or equal to the first time threshold. The first load threshold and the first time threshold are preset, and can be determined according to an actual application scene of the refrigeration system, and are not limited herein. The first holding time refers to a holding time during which the total load variation parameter is smaller than the first load threshold.
In application, the main refrigeration unit 11 may determine whether the total load variation parameter is smaller than the first load threshold, record the first holding time when the total load variation parameter is smaller than the first load threshold, and determine whether the first holding time is greater than or equal to the first time threshold, and send an average load to each slave refrigeration unit 12 in an operating state when the total load variation parameter is smaller than the first load threshold and the first holding time is greater than or equal to the first time threshold, so as to instruct each slave refrigeration unit 12 in the operating state to operate according to the average load.
According to the control method of the refrigerating system, the main refrigerating unit 11 determines the total load change parameters of all the refrigerating units 10 in the running state according to the current load of each refrigerating unit 10 in the running state, and when the total load change parameters are smaller than the first load threshold and the first holding time of the total load change parameters smaller than the first load threshold is larger than or equal to the first time threshold, average loads are sent to each slave refrigerating unit 12 in the running state, namely, the load change condition of the whole refrigerating system is measured through the total load change parameters, and whether the whole refrigerating system is in a relatively stable state is determined by comparing the total load change parameters with the first load threshold and comparing the first holding time with the first time threshold, so that the refrigerating unit 10 is subjected to load balance adjustment under the condition that the whole refrigerating system is in a stable state, the condition that the system is frequently adjusted due to load fluctuation is avoided, the stability of the system is improved, and the energy consumption is reduced.
In one example, the load variation parameter of the refrigeration system includes a single load variation parameter of each refrigeration unit 10 in an operating state. In use, the main refrigeration unit 11 may determine the individual load variation parameter of each refrigeration unit 10 in operation based on the current load of each refrigeration unit 10 in operation. The single load variation parameter is used to represent a single machine variation condition of each refrigeration unit 10 in an operation state in the refrigeration system, and in short, the single load variation parameter represents a load variation condition of one refrigeration unit 10. The magnitude of the single load variation parameter represents the degree of load variation of the refrigeration unit 10 itself. Specifically, the greater the single load variation parameter, the greater the degree of load variation of the refrigeration unit 10 itself; the smaller the single load variation parameter, the smaller the degree of load variation of the refrigeration unit 10 itself.
Based on the above, the step of transmitting the average load to each slave refrigeration unit 12 in the operation state, that is, in the case where the load variation parameter satisfies the preset condition, may include: when the single load variation parameter is smaller than the second load threshold value and the holding time is equal to or longer than the second time threshold value, the average load is transmitted to each slave refrigeration unit 12 in the operating state. The second load threshold and the second time threshold are preset, and can be determined according to an actual application scenario of the refrigeration system, and are not limited herein. The second hold time refers to a hold time during which the single load variation parameter is smaller than the second load threshold. The second load threshold is, for example, less than or equal to the first load threshold and the second time threshold is less than or equal to the first time threshold.
In application, the main refrigeration unit 11 may determine whether the total load variation parameter is smaller than the first load threshold, record the first holding time when the total load variation parameter is smaller than the first load threshold, and determine whether the first holding time is greater than or equal to the first time threshold, and send an average load to each slave refrigeration unit 12 in an operating state when the total load variation parameter is smaller than the first load threshold and the first holding time is greater than or equal to the first time threshold, so as to instruct each slave refrigeration unit 12 in the operating state to operate according to the average load.
According to the control method of the refrigerating system, the main refrigerating unit 11 determines the single load change parameter of each refrigerating unit 10 in the running state according to the current load of each refrigerating unit 10 in the running state, and when the single load change parameter is smaller than the second load threshold and the second holding time of the single load change parameter smaller than the second load threshold is larger than or equal to the second time threshold, the average load is sent to each slave refrigerating unit 12 in the running state, namely, the load change condition of the refrigerating unit 10 is measured through the single load change parameter, and whether each refrigerating unit 10 in the running state in the refrigerating system is in a relatively stable state is determined by comparing the single load change parameter with the second load threshold and comparing the second holding time with the second time threshold, so that the load balance adjustment is carried out on each refrigerating unit 10 in the running state under the condition that each refrigerating unit 10 in the running state is in the stable state, the system is prevented from being frequently adjusted due to load fluctuation, the stability of the system is improved, and the energy consumption is reduced.
In one embodiment, step S202, obtaining the current load of each refrigeration unit 10 in an operating state in the refrigeration system may include: the current load of each refrigeration unit 10 in an operating state in the refrigeration system is periodically acquired according to a preset time. The preset time is preset, and the preset time is a time interval for periodically acquiring the current load of each refrigeration unit 10 in the running state in the refrigeration system. In use, the main refrigeration unit 11 may periodically obtain the current load of each refrigeration unit 10 in operation in the refrigeration system for a predetermined period of time. The current load of the refrigeration unit 10 in the ith cycle may be, for example, a load average value of the refrigeration unit 10 in the ith cycle, a load at a middle time of the ith cycle, or another load value for indicating that the refrigeration unit 10 is in the ith cycle, which is not limited herein.
Based on the above, as shown in fig. 3, the above steps of determining the load variation parameters of the refrigeration system according to the current load of each refrigeration unit 10 in the operation state may include the following steps S302 and S304.
S302: a load difference between the current load of each refrigeration unit 10 in the operation state in the i+1th cycle and the current load in the i-th cycle is obtained.
In use, the main refrigeration unit 11 can obtain the current load D of each refrigeration unit 10 in the operation state in the ith period i And acquiring the current load D of each refrigeration unit 10 in the running state in the (i+1) th period i+1 And determines the current load D of each refrigeration unit 10 in operation during the (i+1) th cycle i+1 With the current load D in the ith period i Is a load difference DeltaD of (a) i+1 =D i+1 - D i 。
S304: the load variation parameter of each refrigeration unit 10 in the operation state in the i+1th cycle is determined according to the load difference value of each refrigeration unit 10 in the operation state and the current load of each refrigeration unit 10 in the operation state in the i th cycle.
In use, the main refrigeration unit 11 may be based on the load differential ΔD of each refrigeration unit 10 i+1 And the current load D of each refrigeration unit 10 in the operational state during the ith cycle i The load variation parameter of each of the refrigeration units 10 in the operation state in the i+1th cycle is determined so that, in the case where the load variation parameter satisfies the preset condition, an average load is transmitted to each of the slave refrigeration units 12 in the operation state to instruct each of the slave refrigeration units 12 in the operation state to operate according to the average load. Illustratively, the load variation parameter includes at least one of a total load variation parameter and a single load variation parameter of each refrigeration unit 10 in an operating state during the i+1th cycle.
For example, in the case where the load variation parameter includes the total load variation parameter of each refrigeration unit 10 in the operation state in the (i+1) -th cycle, the main refrigeration unit 11 may be configured to calculate the load difference Δd of each refrigeration unit 10 in the operation state i+1 Determining a total load change ΣΔd of the refrigeration system over the (i+1) th cycle i+1 And according to each in the operation stateThe current compliance of the refrigeration unit 10 during the ith cycle determines the current total load Σd of the refrigeration system during the ith cycle i And the ratio of the total load variation in the ith period and the current total load of the refrigerating system in the ith period is taken as the total load variation parameter C of each refrigerating unit 10 in the running state in the ith period and the (1) th period i+1 =∑ΔD i+1 /∑D i 。
Still another example, in the case where the load variation parameter includes a single load variation parameter of each refrigeration unit 10 in an operation state in the (i+1) -th cycle, the main refrigeration unit 11 may vary the single load variation Δd of each refrigeration unit 10 in an operation state in the (i+1) -th cycle i+1 The ratio to the current load in the ith cycle is used as the single load variation parameter E of each refrigeration unit 10 in the running state in the (i+1) th cycle i+1 =ΔD i+1 /D i 。
According to the control method of the refrigerating system, the main refrigerating unit 11 periodically acquires the current load of each refrigerating unit 10 in the running state in the refrigerating system according to the preset time, acquires the load difference value between the current load of each refrigerating unit 10 in the running state in the (i+1) th period and the current load of each refrigerating unit 10 in the running state in the (i) th period, and determines the load change parameter of each refrigerating unit 10 in the running state in the (i+1) th period according to the load difference value of each refrigerating unit 10 in the running state and the current load of each refrigerating unit 10 in the running state in the (i) th period.
In one embodiment, as shown in fig. 4, the control method of the refrigeration system may further include the following steps S402 and S404.
S402: the operation time of each refrigeration unit 10 in the operation state is acquired.
In use, the main refrigeration unit 11 may obtain the run time of each refrigeration unit 10 in operation. Wherein the run time is used to represent the total run length of the refrigeration unit 10.
S404: in case that the operation time of the first refrigerating unit 121 in the operation state is greater than the preset time threshold, a shutdown command is transmitted to the first refrigerating unit 121 and an average load is transmitted to the second refrigerating unit 122 in the idle state in the refrigerating system to instruct the first refrigerating unit 121 to stop operating according to the shutdown command and instruct the second refrigerating unit 122 to operate according to the average load.
In application, the main refrigeration unit 11 may send a shutdown instruction to the first refrigeration unit 121 and send an average load to the second refrigeration unit 122 in an idle state in the refrigeration system when the operation time of the first refrigeration unit 121 in an operation state is greater than a preset time threshold, so as to instruct the first refrigeration unit 121 to stop operating according to the shutdown instruction and instruct the second refrigeration unit 122 to operate according to the average load. The preset time threshold is preset, and may be determined according to the actual configuration of the refrigeration unit 10, which is not limited herein.

Wherein the second refrigeration unit 122 is one of the plurality of refrigeration units 10 of the refrigeration system. Illustratively, the number of second refrigeration units 122 is the same as the number of first refrigeration units 121. Illustratively, if the main refrigeration unit 11 determines that the operation time of 2 first refrigeration units 121 in an operation state in the refrigeration system is greater than the preset time threshold, an average load is sent to 2 second refrigeration units 122 in an idle state in the refrigeration system to instruct the 2 second refrigeration units 122 to operate according to the average load, and a shutdown command is sent to the 2 first refrigeration units 121 whose operation time is greater than the preset time threshold to instruct the 2 first refrigeration units 121 to stop operating according to the shutdown command. In practical applications, the main refrigeration unit 11 may further generate operation and maintenance information to prompt a relevant person to overhaul the first refrigeration unit 121 when determining that the operation time of the first refrigeration unit 121 in the operation state is greater than the preset time threshold, so as to improve the reliability of the refrigeration system.
For example, in the case that the number m1 of the second refrigeration units 122 in the idle state in the refrigeration system is smaller than the number of the first refrigeration units 121m2, the main refrigeration unit 11 may send an average load to the m1 second refrigeration units 122 in the refrigeration system and send a shutdown instruction to the m1 first refrigeration units 121 to replace the m1 first refrigeration units to operate by the m1 second refrigeration units, and the main refrigeration unit 11 may also generate a prompt message to prompt that the refrigeration system may not meet the current cooling/heating requirement.
In the control method of the refrigeration system, the operation time of each refrigeration unit 10 in the operation state is obtained through the main refrigeration unit 11, and when the operation time of the first refrigeration unit 121 in the operation state is determined to be greater than the preset time threshold, a shutdown instruction is sent to the first refrigeration unit 121, and an average load is sent to the second refrigeration unit 122 in the idle state in the refrigeration system, so that the first refrigeration unit 121 in the idle state can be replaced by the second refrigeration unit 122 in the idle state to operate according to the average load, the loss of a plurality of refrigeration units 10 in the refrigeration system can be balanced while the refrigeration/heating requirements are met, and the overall service life of the refrigeration system is prolonged.

S510: in the case where the current load variation parameter of each of the refrigeration units 10 in the operating state is less than the second load threshold value and the second holding time is greater than or equal to the second time threshold value, the average load is transmitted to each of the slave refrigeration units 12 in the operating state to indicate that each of the slave refrigeration units 12 in the operating state operates according to the average load.
S512: in the case that the operation time of the first refrigerator group 121 in the operation state is greater than the preset time threshold, a shutdown instruction is transmitted to the first refrigerator group 121 and an average load is transmitted to the second refrigerator group 122 in the idle state to instruct the first refrigerator group 121 to stop operating according to shutdown refrigeration and instruct the second refrigerator group 122 to operate according to the average load.
According to the control method of the refrigerating system, the load of each refrigerating assembly 10 in the running state is regulated in an equalizing mode through the main refrigerating unit 11 under the stable state of the refrigerating system, so that the situation that part of the refrigerating units 10 run at high load and part of the refrigerating units 10 run at low load is avoided, the load equalizing performance of each refrigerating unit 10 in the refrigerating system and the stability of the system are improved, the problems of high loss and high energy consumption of the refrigerating units 10 caused by uneven load are solved, the service life of each refrigerating unit 10 is prolonged, only one refrigerating unit 10 in the refrigerating system is required to determine the average load, the refrigerating units 10 can control themselves according to the average load, the control flow is concise and efficient, the overall energy efficiency of the system is improved, the running time of each refrigerating unit 10 is monitored through the main refrigerating unit 11, the second refrigerating unit 122 with small running loss can be used for replacing the first refrigerating unit 121 with large running loss for a long time, the equalizing performance of each refrigerating unit 10 in the refrigerating system is improved, and the overall energy efficiency of the refrigerating system is further improved.
