Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.
The embodiment of the invention provides a cabinet refrigeration control scheme, which is used for combining an air-conditioning refrigeration system and a fan refrigeration system, intelligently selecting a cabinet refrigeration mode, saving energy consumption and simultaneously ensuring the stable operation of a cabinet.
Referring to fig. 1, a structural schematic diagram of a cabinet provided in an embodiment of the present invention is shown. The cabinet mainly comprises a cabinet body, an air-conditioning refrigeration system, a fan refrigeration system, a display screen, various sensors, a control module and the like. The cabinet refrigeration scheme provided by the embodiment of the invention is suitable for a single cabinet as shown in fig. 1 and a cabinet formed by combining multiple cabinets, the control scheme and the working principle of the refrigeration of the multi-cabinet combined cabinet are consistent with those of the single cabinet, and the following embodiment of the invention takes the single cabinet as an example for explanation.
As shown in fig. 2, in the method for controlling cooling of a cabinet provided in an embodiment of the present invention, the cabinet includes a fan cooling system and an air-conditioning cooling system, and the method may include the following steps:
step 201, obtaining the temperature and humidity of the environment where the cabinet is located.
In a specific implementation, the ambient temperature and humidity of the environment where the cabinet is located are collected by the ambient temperature sensor and the humidity sensor shown in fig. 1.
Step 202, under the condition that the fan refrigerating system is determined to be allowed, if the temperature and the humidity of the environment where the cabinet is located meet the first preset conditions, the fan refrigerating system is controlled to be started, and the air conditioner refrigerating system is controlled to be closed.
When the fan refrigerating system is allowed to be used and the temperature and the humidity of the environment where the cabinet is located meet first preset conditions, the fan refrigerating system is started, the monitoring system of the cabinet sends an instruction, the control module controls the fan to be started, cold air outside the cabinet is sucked in from the front door of the cabinet to refrigerate equipment in the cabinet, and meanwhile, the air conditioner refrigerating system is controlled to be closed.
Wherein, the first preset condition comprises: the temperature of the environment where the cabinet is located is smaller than a first preset starting temperature threshold, is larger than a second preset starting temperature threshold, and the humidity of the environment where the cabinet is located is smaller than a first humidity threshold.
In a possible implementation manner, under the condition that the fan refrigerating system is determined to be prohibited from being started or under the condition that the fan refrigerating system is determined to be allowed, if the temperature and the humidity of the environment where the cabinet is located are determined not to meet the first preset conditions, the air-conditioning refrigerating system is controlled to be started.
In practical application, as shown in fig. 3, a working flow diagram of an air-conditioning refrigeration system firstly judges whether a fan refrigeration system is allowed, and under the condition that the fan refrigeration system is determined to be allowed, the fan refrigeration system is started; and controlling to start the air-conditioning refrigeration system under the condition of determining that the fan refrigeration system is prohibited to be started.
In specific implementation, aiming at equipment with high humidity requirement, the humidity detection can be added in the cabinet, the humidity requirement value can be set, and when the humidity in the cabinet does not meet the preset requirement, the fan refrigerating system is immediately withdrawn, and the air conditioner refrigerating system is controlled to be started.
In specific implementation, when the air conditioning refrigeration system breaks down (the refrigerating capacity is insufficient) and the high temperature in the cabinet gives an alarm, the fan refrigeration system is started, and the emergency mode is realized at the moment. As shown in fig. 4, when the air conditioning cooling system fails and a high temperature inside the cabinet gives an alarm, the emergency mode is turned on to determine whether the ambient temperature is lower than the temperature of the cooling channel in the cabinet, and if the ambient temperature is lower than the temperature of the cooling channel, the fan cooling system is turned on.
It should be noted that, when the cabinet works normally, the fan refrigeration system and the emergency mode are mutually exclusive, and meanwhile, the fan refrigeration system and the air-conditioning refrigeration system are mutually exclusive.
In an example, as shown in fig. 5, a schematic diagram of a fan refrigeration system start logic is obtained by first determining whether the fan refrigeration system is allowed to be started, performing start determination on the fan refrigeration system under the condition that the fan refrigeration system is determined to be allowed, and starting the fan refrigeration system if the start determination meets requirements.
The upper and lower limit values of the ambient temperature and the humidity allowed to enter the fan refrigeration system, namely the first preset starting temperature threshold value, the second preset starting temperature threshold value and the first humidity threshold value, and the upper and lower limit values of the temperature of the cold and hot channels allowed to enter the lower cabinet of the fan refrigeration system can be set. If not, the system will run using default values. Wherein the first preset starting temperature threshold may be set at 28 degrees celsius (° c), the second preset starting temperature threshold may be set at 10 ℃, and the first humidity threshold may be set at 80%.
In other embodiments of the present invention, all of the above related limits may be set independently, and are not hooked to the alarm value.
In practical application, the fan refrigerating system can be started through the following steps:
the first step is as follows: setting a first preset starting temperature threshold value, a second preset starting temperature threshold value, a first humidity threshold value and an upper and lower temperature limit value in the cabinet.
The system comprises a cabinet, a cold channel, a first preset starting temperature threshold value = cold channel high temperature limit value = cabinet inner cold channel high temperature alarm value-temperature dead zone, wherein the cabinet inner cold channel high temperature alarm value and the temperature dead zone can be set according to empirical values. For example, the high temperature alarm value of the cold channel in the cabinet can be set to 30 ℃ and the temperature dead zone can be set to 2 ℃.
And the second preset starting temperature threshold = cold channel low-temperature limit = cold channel low-temperature alarm value in the cabinet.
The hot channel high temperature limit = hot channel high temperature alarm value-temperature dead zone in the cabinet, wherein the hot channel high temperature alarm value and the temperature dead zone in the cabinet can be set according to empirical values. For example, the in-cabinet heat path high temperature alarm value may be set to 45 ℃ and the temperature dead zone may be set to 2 ℃.
The second step is that: the fan refrigeration system is manually set to allow startup.
The third step: through ambient temperature sensor and humidity transducer, gather the temperature and the humidity of the environment that the rack is located, if satisfy the requirement after the judgement, will start fan refrigerating system.
In one example, as shown in fig. 6, after the fan refrigeration system is turned on, the fan refrigeration system is turned off, whether the temperature in the cold channel and the temperature of the environment where the cabinet is located are greater than a first preset threshold (e.g., -3 ℃), if the temperature in the cold channel and the temperature in the environment where the cabinet is located are greater than the first preset threshold, the fan is started, the fan is operated for a preset time (e.g., 3 minutes) after the fan is started, whether an exit condition is met during the operation of the fan refrigeration system is determined, and the fan refrigeration system is exited when the exit condition is met. Specifically, it mainly comprises the following steps:
step 601, obtaining the temperature of a cold channel in the cabinet, and after a fan refrigerating system is started, starting a fan when the difference between the temperature in the cold channel and the temperature of the environment where the cabinet is located is determined to be greater than a first preset threshold value so as to avoid the occurrence of condensed water in the cabinet. In another embodiment, the fan may be turned on after the temperature in the cold aisle is determined to be higher than the ambient temperature of the cabinet. Wherein, the running time of the fan refrigerating system is at least 3 minutes so as to achieve the effect of refrigerating the cabinet. In particular implementations, the fan refrigeration system may operate without a minimum run time.
Step 602, judging whether the fan refrigeration system meets an exit condition all the time in the operation process, and exiting the fan refrigeration system when the exit condition is met. Specific fan refrigeration system exit logic see the schematic diagram of fan refrigeration system exit logic shown in fig. 7.
In one example, the fan refrigeration system exits the logic schematic, as shown in fig. 7, with the following specific steps:
step one, judging the exit reason;
secondly, adopting different strategies for exiting logic according to the judgment result of the exit reason;
and thirdly, starting judgment of the next refrigerating system after a time delay after exiting. In specific implementation, the delay processing is not needed after the fan refrigerating system exits, and the fan refrigerating system can be immediately entered when the temperature and the humidity of the environment where the cabinet is located meet the first preset conditions.
Wherein, the exit logic is the following five types:
exit logic 1: in the operation process of the fan refrigeration system, if the temperature in the cold channel is smaller than a first temperature threshold value, the fan is turned off, and when the temperature in the cold channel is determined to be larger than the first temperature threshold value, the fan is turned on again. In particular implementations, the fan may also be turned back on when it is determined that the temperature within the cold aisle is greater than the second temperature threshold. Wherein the first temperature threshold may be set to 10 deg.c and the second temperature threshold may be set to 13 deg.c.
Exit logic 2: and in the running process of the fan refrigerating system, if the temperature of the environment where the cabinet is located is greater than the second temperature threshold value, starting the air conditioner refrigerating system, closing the fan refrigerating system, and recording the running power of the cabinet when the fan refrigerating system is closed.
Exit logic 3: and in the operation process of the fan refrigerating system, if the humidity of the environment where the cabinet is located is greater than a second humidity threshold value, starting the air-conditioning refrigerating system, closing the fan refrigerating system, and recording the operation power of the cabinet when the fan refrigerating system is closed. In specific implementation, the delay processing is not needed after the fan refrigerating system exits, and the fan refrigerating system can be immediately entered when the temperature and the humidity of the environment where the cabinet is located meet the first preset conditions.
Exit logic 4: in the operation process of the fan refrigeration system, if the temperature in the cold channel is greater than the third temperature threshold, the air-conditioning refrigeration system is started, the fan refrigeration system is closed, the operation power of the cabinet when the fan refrigeration system is closed is recorded, the first preset starting temperature threshold is updated to be the difference between the temperature of the environment where the cabinet is located and the preset value, and the preset value in the exemplary embodiment is 1.
Exit logic 5: in the operation process of the fan refrigeration system, if the temperature of the heat channel in the cabinet acquired in real time is greater than the third temperature threshold, the air-conditioning refrigeration system is started, the fan refrigeration system is closed, the operation power of the cabinet when the fan refrigeration system is closed is recorded, the first preset starting temperature threshold is updated to be the difference between the temperature of the environment where the cabinet is located and the preset value, and the preset value is 1 in the exemplary embodiment.
The running power of all fan refrigerating systems exiting the recording cabinet is used for dealing with the condition of load reduction in the cabinet. And after the fan refrigerating system is closed, acquiring the current average power of the cabinet, and resetting the first preset starting temperature threshold value to an initial value when the recorded difference between the running power of the cabinet and the current average power of the cabinet when the fan refrigerating system is closed is larger than a preset power threshold value.
In specific implementation, on the basis of the exit logic, an intelligent identification function can be added, a part of functions are mainly added in the exit logic, and one-time selection judgment is added in the entry and exit logic. The method comprises the following specific steps:
firstly, in the exit logic of the fan refrigeration system, the exit reason needs to be recorded every time, the exit reason meeting the requirements is recorded into a table, and a two-dimensional graph of the corresponding relation between the load capacity and the ambient temperature is drawn.
After the fan refrigeration system is withdrawn each time, the power value, the temperature of the environment where the cabinet which is withdrawn from the fan refrigeration system is located and the running time length need to be recorded in the system, the withdrawal reason is judged, and data meeting the requirements are made into a fan refrigeration intelligent identification comparison table, as shown in fig. 8. A two-dimensional map of the belt load versus ambient temperature may also be made from the table, as shown in fig. 9.
And secondly, when the fan refrigerating system enters an exit logic, judging the area of the current load rate and the temperature corresponding point each time.
If the measured corresponding point of the current environment temperature and the load amount falls in the area of FIG. 9, the fan cooling mode can be directly entered, and the long-term stable operation can be kept. The newly added function has a certain self-learning function, after long-term stable operation, the accuracy of an ambient temperature-loading capacity curve graph can be improved, the matching time of the ambient temperature and the loading capacity in the cabinet can be effectively reduced, the exit frequency of the fan refrigerating system is reduced, and the fan refrigerating system is more stable. If the startup limit is modified in the fan cooling mode, the table shown in FIG. 8 and the curve shown in FIG. 9 are reset.
The fan refrigeration system starting logic schematic diagram with the added intelligent identification function is as shown in fig. 10, and firstly, whether the fan refrigeration system is allowed to be started is judged, under the condition that the fan refrigeration system is determined to be allowed, whether the current power and the pipe diameter temperature corresponding point where the cabinet is located are out of a two-dimensional graph curve area with the corresponding relation between the loading capacity and the environment temperature is searched, if the condition is met, the fan refrigeration system is further judged to be started, and if the condition is not met, the fan refrigeration system is started.
In specific implementation, when the exit logics of the fan refrigerating system are 2 and 3, the temperature and the humidity of the environment where the cabinet is located need to be collected. The temperature and humidity of the environment where the cabinet is located are collected by using a calculation logic diagram of the temperature and humidity of the environment where the cabinet is located as shown in fig. 11, and referring to fig. 11, the calculation logic steps of the temperature of the environment where the cabinet is located are as follows:
step one, in a preset time period, the preset time period is set to 10 minutes in the present exemplary embodiment, and the temperature of the environment where the cabinet is located is collected at a plurality of times;
and secondly, calculating the average temperature of the environment where the cabinet is located within a preset time length, and judging the fluctuation condition of the average temperature value.
The first condition is as follows: when the average temperature value fluctuates above and below the fan refrigeration starting limit value, the environment temperature is judged to be smaller than the starting limit value;
and a second condition: when the temperature sampling values within the preset time are all larger than the fan refrigeration starting limit value, judging that the environmental temperature is larger than the starting limit value;
and a third situation: and when the temperature sampling value within the preset time is greater than the sum of the fan refrigeration starting limit value and the preset value, wherein the preset value is set to be 2, judging that the environmental temperature is greater than the starting limit value.
The logic steps of the calculation of the environmental humidity of the cabinet are as follows:
step one, in a preset time period, the preset time period is set to 10 minutes in the present exemplary embodiment, and the humidity of the environment where the cabinet is located is collected at a plurality of times;
secondly, calculating the average humidity of the environment where the cabinet is located within a preset time period, and judging the fluctuation condition of the average humidity value: and when the average humidity value within the preset time length of 65% is greater than the first humidity threshold value, judging that the environmental humidity is greater than the starting limit value.
In specific implementation, in order to cope with temperature changes in a short time caused by large fluctuation of temperature and humidity of an environment where the cabinet is located in a short time and load changes in the cabinet, after the fan refrigeration system exits, the fan refrigeration system needs to wait for a period of time (for example, 10 minutes), and then the fan refrigeration system is allowed to enter the fan refrigeration mode again. And judging whether the temperature and the humidity of the environment where the cabinet is located meet a first preset condition for reentering the fan refrigeration system or not within the waiting time after the fan refrigeration system exits.
