Description

Technical Field

[0001] This invention relates to the technical field of refrigeration equipment control, and in particular to a control method, apparatus, electronic device, and storage medium for refrigeration equipment. Background Technology

[0002] Currently, air conditioning units installed and used in communication, data, and switching rooms generally employ two temperature control methods: supply air temperature control and return air temperature control. These two methods are options for controlling the temperature in a computer room, differing only in the location of the temperature sampling points involved in the control.

[0003] For a closed computer room, with a constant load inside the room:

[0004] If return air temperature control is used, the return air temperature is the directly controlled object; if supply air temperature control is used, the supply air temperature is the directly controlled object.

[0005] Currently, the most common temperature control method used in computer rooms is return air temperature control. This involves using temperature sensors on the return air side of the chiller unit to collect temperature values, comparing these values ​​with the set target temperature, and then controlling the chiller's cooling output and other components based on the calculated cooling demand. For example, when the return air temperature is higher than the target temperature, the cooling output is increased; when the return air temperature is lower than the target temperature, the cooling output is reduced. While this method can control the temperature of the computer room, it is not intelligent enough and may lead to excessive increases or decreases in cooling output, resulting in overheating or unnecessary waste.

[0059] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0060] To avoid excessively increasing or decreasing cooling output, which could lead to overheating of the computer room or unnecessary waste, this invention provides a control method for refrigeration equipment. This method selects different temperature adjustment strategies based on the difference between the set temperature and the current actual area temperature, and controls different types of refrigeration equipment sequentially according to these strategies. This achieves more precise temperature control, avoiding both unnecessary waste caused by excessively increasing cooling output and potential overheating of the computer room due to excessively decreasing cooling output.

[0061] Reference Figure 1 The diagram illustrates a step flowchart of a control method for a refrigeration device according to an embodiment of the present invention. The refrigeration device may include various types. The method may include the following steps:

[0062] Step 101: Obtain the set temperature for the area targeted by the refrigeration equipment, and the current area temperature of the area targeted by the refrigeration equipment.

[0063] The set temperature can refer to a temperature set in advance for the area targeted by the cooling equipment. Under this set temperature, the equipment in the computer room can maintain normal operation and thus stably provide services to the outside world.

[0064] Zone temperature can refer to the temperature measured in the area targeted by the refrigeration equipment, and this zone temperature can be the return air temperature.

[0065] In practical applications, the temperature of multiple areas targeted by the refrigeration equipment can be measured at preset intervals to obtain the temperature of multiple areas in succession.

[0066] After obtaining the regional temperature, you can also obtain the preset temperature for the region targeted by the refrigeration equipment.

[0067] Step 102: Determine the target difference between the set temperature and the area temperature.

[0068] After obtaining the set temperature and the area temperature, the difference between the set temperature and the area temperature can be calculated and used as the target difference.

[0069] Step 103: Determine the target temperature difference range to which the target difference belongs, and determine the target temperature adjustment strategy set for the target temperature difference range.

[0070] After calculating the target difference between the set temperature and the area temperature, the target temperature difference range to which the target difference belongs can be determined.

[0071] In practical applications, different temperature control strategies can be preset for different temperature difference ranges. The temperature control strategy can be determined according to the magnitude of the temperature difference in order to achieve more precise temperature control.

[0072] Therefore, after determining the target temperature difference range, the target temperature regulation strategy pre-set for the target temperature difference range can be determined.

[0073] Step 104: Control different types of refrigeration equipment in sequence according to the target temperature adjustment strategy.

[0074] Then, the temperature can be adjusted according to the target temperature adjustment strategy. Specifically, different types of refrigeration equipment can be controlled sequentially according to the target temperature adjustment strategy to achieve more precise temperature regulation. For example, when the area temperature is higher than the set temperature, the speed of the fan equipment can be increased first to more quickly output the cold air generated by the cold source equipment to the computer room, thereby avoiding waste of resources. When increasing the speed of the fan equipment is insufficient to cool the computer room, the cooling capacity of the cold source equipment can be increased. This embodiment of the invention does not limit this.

[0075] In this embodiment of the invention, a set temperature is obtained for the area targeted by the refrigeration equipment, along with the current temperature of the area. A target difference between the set temperature and the area temperature is determined. The target temperature difference range to which the target difference belongs is determined, and a target temperature adjustment strategy is set for the target temperature difference range. Based on the target temperature adjustment strategy, different types of refrigeration equipment are controlled sequentially. This embodiment of the invention achieves more precise temperature control of the computer room, avoiding unnecessary waste caused by excessively increasing cooling output, and also avoiding potential overheating problems caused by excessively reducing cooling output.

[0076] Reference Figure 2 This diagram illustrates a flowchart of another control method for a refrigeration device according to an embodiment of the present invention. The refrigeration device may include a cold source device and a fan device. The cold source device may refer to a device that generates a cold source, such as a water valve, a refrigerant pump, or a compressor. The fan device may refer to a fan, etc.

[0077] Specifically, the method may include the following steps:

[0078] Step 201: Obtain the set temperature for the area targeted by the refrigeration equipment, and the current area temperature of the area targeted by the refrigeration equipment.

[0079] In practical applications, the temperature of multiple areas targeted by the refrigeration equipment can be measured at preset intervals to obtain the temperature of multiple areas in succession.

[0080] After obtaining the regional temperature, you can also obtain the preset temperature for the region targeted by the refrigeration equipment.

[0081] Step 202: Determine the target difference between the set temperature and the area temperature.

[0082] After obtaining the set temperature and the area temperature, the difference between the set temperature and the area temperature can be calculated and used as the target difference.

[0083] Step 203: Determine the target temperature difference range to which the target difference belongs, and determine the target temperature adjustment strategy set for the target temperature difference range.

[0084] After calculating the target difference between the set temperature and the area temperature, the target temperature difference range to which the target difference belongs can be determined.

[0085] In practical applications, different temperature control strategies can be preset for different temperature difference ranges. The temperature control strategy can be determined according to the magnitude of the temperature difference in order to achieve more precise temperature control.

[0086] Therefore, after determining the target temperature difference range, the target temperature regulation strategy pre-set for the target temperature difference range can be determined.

[0087] As an example, the target temperature regulation strategy may include a first target temperature regulation strategy, a second target temperature regulation strategy, a third target temperature regulation strategy, and a fourth target temperature regulation strategy. Of course, it may also include a fifth and a sixth target temperature regulation strategy, which can be set according to specific circumstances. This embodiment of the invention does not limit this.

[0088] Step 204: When the target temperature regulation strategy is the first target temperature regulation strategy, the cooling capacity of the cold source equipment is gradually reduced according to the first preset cycle and the first preset step size.

[0089] In practical applications, when the target difference is within the first temperature difference range, the target temperature regulation strategy can be determined as the first target temperature regulation strategy. The temperature difference range can include [-∞, T1], [T1, T2], [T2, T3], [T3, T4] and [T4, +∞], T1 < T2 < 0 < T3 < T4, and |T1| = |T4|, |T2| = |T3|. The first temperature difference range can be [T1, T2].

[0090] When the target temperature regulation strategy is determined to be the first target temperature regulation strategy, it can be assumed that the current cooling capacity supplied to the computer room is slightly excessive. At this time, the cooling capacity of the cold source equipment can be gradually reduced according to the first preset cycle and the first preset step size set in the first target temperature regulation strategy to reduce unnecessary resource waste.

[0091] Step 205: During the process of reducing the cooling capacity of the cold source equipment, when a new target difference is detected to be within the preset temperature difference range, stop reducing the cooling capacity of the cold source equipment.

[0092] During the process of gradually reducing the cooling capacity of the cold source equipment according to the first preset cycle and the first preset step size, the temperature of the area can be continuously detected and new target differences can be continuously obtained.

[0093] When a new target difference is detected to be within a preset temperature difference range, the reduction of the cooling capacity of the cold source equipment can be stopped, and the cold source equipment can be controlled with the current cooling capacity. The preset temperature difference range can be [T2, T3].

[0094] Step 206: When the new target difference is still not within the preset temperature difference range after N adjustments, the speed of the fan equipment is gradually reduced according to the second preset cycle and the second preset step size; where N is a positive integer.

[0095] In practical applications, if after N adjustments the new target difference is still not within the preset temperature difference range, it can be assumed that the temperature of the computer room is still lower than the set temperature. At this point, the fan equipment can be further controlled. Specifically, the fan speed can be gradually reduced according to the second preset cycle and the second preset step size to further reduce resource waste.

[0096] Where N can be a positive integer, for example, 5, but this embodiment of the invention does not limit it.

[0097] Step 207: When the target temperature regulation strategy is the second target temperature regulation strategy, the speed of the fan equipment is gradually increased according to the third preset cycle and the third preset step size.

[0098] In practical applications, when the target difference is within the second temperature difference range, the target temperature regulation strategy can be determined as the second target temperature regulation strategy; the first temperature difference range can be [T3, T4].

[0099] When the target temperature regulation strategy is determined to be the second target temperature regulation strategy, it can be assumed that the current cooling capacity supplied to the computer room is slightly insufficient. In this case, the fan speed can be gradually increased according to the second preset cycle and second preset step size set in the second target temperature regulation strategy. This will first reduce the temperature of the computer room by increasing the circulation speed of the cold air output from the cold source equipment. Compared with directly increasing the cooling capacity of the cold source equipment, this can reduce unnecessary waste of resources.

[0100] Step 208: During the process of increasing the speed of the fan equipment, when a new target difference is detected to be within the preset temperature difference range, stop increasing the speed of the fan equipment.

[0101] While gradually increasing the speed of the fan equipment according to the second preset cycle and the second preset step size, the temperature of the area can be continuously detected and new target differences can be continuously obtained.

[0102] When a new target difference is detected to be within a preset temperature difference range, the gradual increase in the fan speed can be stopped, and the fan speed can be used to control the fan.

[0103] Step 209: When the new target difference is still not within the preset temperature difference range after M adjustments, gradually increase the cooling capacity of the cold source equipment according to the fourth preset cycle and the fourth preset step size; where M is a positive integer.

[0104] In practical applications, if after M adjustments the new target difference is still not within the preset temperature difference range, it can be assumed that the temperature of the computer room is still higher than the set temperature. At this point, the cooling source equipment can be further controlled. Specifically, the cooling capacity of the cooling source equipment can be gradually increased according to the fourth preset cycle and the fourth preset step size to cool down the computer room as soon as possible, thereby avoiding the computer room temperature from being too high and causing the equipment in the computer room to malfunction.

[0105] Where M can be a positive integer, for example, 5, but this embodiment of the invention does not limit it.

[0106] Step 210: When the target temperature regulation strategy is the third target temperature regulation strategy, gradually reduce the cooling capacity of the cold source equipment according to the fifth preset cycle and the fifth preset step size; and gradually reduce the speed of the fan equipment according to the sixth preset cycle and the sixth preset step size.

[0107] In practical applications, when the target difference is within the third temperature difference range, the target temperature regulation strategy can be determined as the third target temperature regulation strategy; the third temperature difference range can be [-∞, T1].

[0108] When the target temperature regulation strategy is determined to be the third target temperature regulation strategy, it can be assumed that the current cooling capacity supplied to the computer room is excessive. In this case, the cooling capacity of the cold source equipment can be gradually reduced according to the fifth preset cycle and the fifth preset step size set in the third target temperature regulation strategy to reduce unnecessary resource waste. Specifically, in order to make the area temperature approach the set temperature as quickly as possible, the fifth preset cycle can be shorter than the first preset cycle, and the fifth preset step size can be longer than the first preset step size.

[0109] When reducing the cooling capacity of the cold source equipment, the fan speed can be gradually reduced simultaneously according to the sixth preset cycle and the sixth preset step size set in the third target temperature adjustment strategy. The sixth preset cycle is shorter than the second preset cycle, and the sixth preset step size is longer than the second preset step size.

[0110] Step 211: During the process of reducing the cooling capacity of the cold source equipment and reducing the speed of the fan equipment, when a new target difference is detected to be within the preset temperature difference range, stop reducing the cooling capacity of the cold source equipment and stop reducing the speed of the fan equipment.

[0111] In the process of gradually reducing the cooling capacity of the cold source equipment according to the fifth preset cycle and the fifth preset step size, and gradually reducing the speed of the fan equipment according to the sixth preset cycle and the sixth preset step size, the temperature of the area can be continuously detected and new target differences can be continuously obtained.

[0112] When a new target difference is detected to be within the preset temperature difference range, the reduction of the cooling capacity of the cold source equipment and the reduction of the fan speed can be stopped, and the cold source equipment and the fan equipment can be controlled with the current cooling capacity and the current speed.

[0113] Step 212: When the cold source equipment and fan equipment are adjusted to the lowest opening degree, and the new target difference is still not within the preset temperature difference range, turn off the cold source equipment and fan equipment.

[0114] Conversely, if the new target temperature difference is still not within the preset temperature difference range after adjusting the cooling source equipment and fan equipment to their lowest operating levels, it can be assumed that the current method cannot make the area temperature match the set temperature. In this case, the cooling source equipment and fan equipment can be directly turned off to raise the temperature of the computer room.

[0115] Step 213: When the target temperature regulation strategy is the fourth target temperature regulation strategy, gradually increase the cooling capacity of the cold source equipment according to the seventh preset cycle and the seventh preset step size; and gradually increase the speed of the fan equipment according to the eighth preset cycle and the eighth preset step size.

[0116] In practical applications, when the target difference is in the fourth temperature difference range, the target temperature regulation strategy can be determined as the fourth target temperature regulation strategy; where the fourth temperature difference range can be [T4, +∞).

[0117] When the target temperature regulation strategy is determined to be the fourth target temperature regulation strategy, it can be assumed that the current cooling capacity supplied to the computer room is insufficient. In this case, the cooling capacity of the cold source equipment can be gradually increased according to the seventh preset cycle and the seventh preset step size set in the fourth target temperature regulation strategy. The seventh preset cycle can be shorter than the third preset cycle, and the seventh preset step size can be longer than the third preset step size, so as to reduce the temperature of the computer room as quickly as possible.

[0118] When increasing the cooling capacity of the cold source equipment, the speed of the fan equipment can be gradually increased according to the eighth preset cycle and the eighth preset step size set in the fourth target temperature regulation strategy; wherein, the eighth preset cycle can be shorter than the fourth preset cycle, and the eighth preset step size can be longer than the fourth preset step size.

[0119] Step 214: During the process of increasing the cooling capacity of the cold source equipment and increasing the speed of the fan equipment, when a new target difference is detected to be within the preset temperature difference range, stop increasing the cooling capacity of the cold source equipment and stop increasing the speed of the fan equipment.

[0120] In the process of gradually increasing the cooling capacity of the cold source equipment according to the seventh preset cycle and the seventh preset step size, and gradually increasing the speed of the fan equipment according to the eighth preset cycle and the eighth preset step size, the temperature of the area can be continuously monitored and new target differences can be continuously obtained.

[0121] When a new target difference is detected to be within the preset temperature difference range, the cooling capacity of the cold source equipment and the speed of the fan equipment can be stopped, and the cold source equipment and the fan equipment can be controlled with the current cooling capacity and the current speed.

[0122] Step 215: When the cold source equipment and fan equipment are adjusted to the highest opening degree, and the new target difference is still not within the preset temperature difference range, an alarm is triggered.

[0123] Conversely, if the target temperature difference is still not within the preset temperature difference range after adjusting the cooling source equipment and fan equipment to their maximum operation, it can be considered that the current method cannot make the area temperature match the set temperature. In this case, a high-temperature alarm can be issued for the area so that staff can intervene to prevent the computer room from experiencing continuous high temperatures that could affect the equipment's ability to provide services.

[0124] Step 216: When the target temperature regulation strategy is the fifth target temperature regulation strategy, when the set temperature is higher than the regional temperature, the cooling capacity of the cold source equipment is gradually reduced according to the ninth preset cycle and the ninth preset step size.

[0125] In practical applications, when the target difference is in the fifth temperature difference range, the target temperature regulation strategy can be determined as the fifth target temperature regulation strategy; where the first temperature difference range can be [T2, T3].

[0126] When the target temperature regulation strategy is determined to be the fifth target temperature regulation strategy, it can be assumed that the current area temperature of the computer room is close to the set temperature. At this time, the cooling source equipment or fan equipment can be controlled according to the relationship between the area temperature and the set temperature.

[0127] Specifically, if the set temperature is higher than the area temperature, then the current temperature of the computer room can be considered slightly lower than the set temperature, indicating excess cooling capacity. In this case, the cooling capacity of the cold source equipment can be gradually reduced according to the ninth preset cycle and the ninth preset step size in the fifth target temperature adjustment strategy. The ninth preset cycle is longer than the first preset cycle, and the ninth preset step size is shorter than the first preset step size.

[0128] Step 217: When the temperature of the area is higher than the set temperature, gradually increase the speed of the fan equipment according to the ninth preset cycle and the ninth preset step size.

[0129] Conversely, if the area temperature is higher than the set temperature, it can be assumed that the current temperature of the computer room is slightly higher than the set temperature and the cooling capacity is insufficient. In this case, the fan speed can be gradually increased according to the ninth preset cycle and the ninth preset step size in the fifth target temperature adjustment strategy.

[0130] It should be noted that the above different strategies can be executed sequentially in real time according to the current target difference. For example, when the target difference is in the third temperature difference range, the third temperature adjustment strategy can be used first; when the new target difference drops to the first temperature difference range, the first temperature adjustment strategy can be used. This embodiment of the invention does not limit this.

[0131] Of course, you can also control the refrigeration equipment directly based on a strategy.

[0132] In one embodiment of the present invention, the above method may further include the following steps:

[0133] Continuously collect regional temperatures; when the temperatures of multiple consecutive regions show a fluctuating trend, and the fluctuation trend disappears, operate different types of refrigeration equipment with the operating parameters before the fluctuation occurred.

[0134] In practical applications, the temperature of a computer room may fluctuate due to the opening and closing of the room door. This fluctuation is not caused by the equipment inside the room. If the power of the cooling equipment is reduced or increased, it may lead to overheating or undercooling when the room door is no longer opened and closed frequently. Therefore, embodiments of the present invention can continuously collect and store the temperature of the computer room area.

[0135] After collecting temperatures from multiple consecutive areas, it can be determined whether the current temperatures of these multiple consecutive areas show a fluctuating trend; if there is a fluctuating trend, it can be assumed that there is a situation of frequent opening and closing of the machine room door.

[0136] Before the fluctuations disappear, the temperature of the computer room can be adjusted by increasing or decreasing the power of the cooling equipment; if the fluctuation trend is detected to have disappeared, the various types of cooling equipment can be operated with the operating parameters before the fluctuations occurred.

[0137] In another embodiment of the present invention, the above method may further include the following steps:

[0138] Determine the heat load of the working equipment in the area; calculate the cooling demand based on the heat load and the cooling capacity of the refrigeration equipment; control different types of refrigeration equipment according to the cooling demand.

[0139] When adjusting the temperature, the cooling equipment can be controlled according to the working status of the equipment in the area; the equipment can refer to the equipment in the computer room that provides services to the outside world, such as servers.

[0140] Specifically, the heat load of the working equipment in the area can be determined first based on the working conditions of the working equipment.

[0141] After determining the heat load of the working equipment in the area, the cooling demand of the working equipment can be calculated based on the heat load and the cooling capacity of the refrigeration equipment. This means that the cooling capacity required to maintain a certain temperature under the current operating power of the working equipment can be obtained. This cooling capacity can be calculated based on the power of the refrigeration equipment.

[0142] After calculating the cooling capacity requirement, control parameters for different refrigeration devices can be generated, and each refrigeration device can be controlled based on these control parameters. This embodiment of the invention does not limit this.

[0143] In this embodiment of the invention, a set temperature is obtained for the area targeted by the refrigeration equipment, along with the current temperature of that area. A target difference between the set temperature and the area temperature is determined. The target temperature difference range to which the target difference belongs is determined, and a target temperature adjustment strategy is set for that range. Based on the target temperature adjustment strategy, different types of refrigeration equipment are controlled sequentially. This embodiment of the invention achieves more precise temperature regulation of the computer room under different temperature differences, avoiding unnecessary waste caused by excessively increasing cooling output and preventing overheating of the computer room due to excessively decreasing cooling output.

[0144] Next, the control method of the above refrigeration equipment will be described in combination with specific examples:

[0145] 1. Machine room heat load = equipment heat load (equipment power * 0.8) + ambient heat load (0.15 - 0.18 * machine room area).

[0146] 2. Cooling capacity demand = (machine room heat load / terminal unit cooling capacity * 0.8) + 1, to determine the minimum number of refrigeration inputs required for the terminal unit to be satisfied.

[0147] 3. Calculate the required air circulation rate in the machine room: To avoid the heat island effect in the machine room as much as possible and control the energy consumption of the terminal unit, according to the test data, the air circulation rate in the machine room per hour should be controlled between 30 - 60 times. According to the performance curve of the terminal unit fan, the air volume and energy consumption curve are more economical when the rotational speed is controlled within the range of R min -R max . The air volume of the terminal unit fan is proportional to the rotational speed. Therefore, the minimum demand of the terminal unit is calculated according to the air volume of 30 cycles at Rmin, and the maximum number of terminal units that can be put into operation is calculated according to the air volume of 60 cycles at R max .

[0148] 4. Determine the number of air conditioning terminal units to be put into operation: Compare the minimum demand of the cooling capacity demand with the minimum demand of the air circulation rate in the machine room, and round up the larger number of units as the number of terminal units to be put into operation in the machine room.

[0149] 5. Set the operating range of the air conditioning terminal unit: Enter the terminal unit control system:

[0150] a. Limit the minimum opening of the water valve or compressor frequency conversion range of the terminal unit air conditioner to prevent the phenomenon of cold and hot air short - circuit during operation and avoid obvious temperature fluctuations in the machine room;

[0151] b. According to the performance characteristics of the fan, set the economical and efficient rotational speed range R min -R max to make the fan always operate in the high - efficiency range.

[0152] 6. When the difference between the set temperature Ts of the air conditioner and the detected area temperature Tc in the machine room is less than the allowable temperature fluctuation value t as shown in Figure 3 :

[0153] a. When the temperature Tc in the machine room is lower than the set value Ts of the air conditioning terminal unit (Tc < Ts) and Ts - Tc < t, the air conditioning terminal unit control preferentially reduces the cooling capacity input L of the cold source (such as water valve, fluorine pump or compressor, etc.), such as reducing the opening of the chilled water valve, reducing the frequency of the fluorine pump or compressor, etc. The adjustment amplitude is 3% - 5% per time, the temperature comparison adjustment control period is 10 - 15 seconds per time, and after adjusting 3 - 5 times, the fan rotational speed R is synchronously reduced, with a reduction amplitude of 10% per time.

[0154] b. When -t < Ts - Tc, the temperature in the machine room is higher than the set value of the air-conditioning terminal unit (Tc > Ts). The air-conditioning terminal unit controls to preferentially increase the fan speed R, with each adjustment amplitude being 10% - 15%. The adjustment control period is 10 - 15 seconds per time. After adjusting 3 times, start to synchronously increase the cooling capacity input L of the cold source (such as water valve, fluorine pump or compressor, etc.), such as increasing the opening of the chilled water valve, the frequency of the fluorine pump, the frequency increase of the compressor, etc., with the adjustment amplitude being 3% - 5% per time.

[0155] c. When the temperature approaches the set value (Tc ≈ Ts) and reaches the control accuracy t* of the air-conditioning terminal unit, -t* < Ts - Tc < t*, temporarily maintain the current settings, and double the adjustment control period (t > t*).

[0156] 7. As Figure 4 shown, set up an operation data buffer, and store operation parameters such as the air-conditioning set temperature value Ts, the allowable temperature fluctuation value t, the detected temperature Tc in the machine room, the fan speed R, and the input L of the cold source in the buffer.

[0157] a. When there is a parameter missing or unable to be obtained, the system maintains the current operating state and immediately issues an alarm to remind the maintenance personnel to intervene and handle it;

[0158] b. Periodically store the relevant parameters into the buffer during the operation process to form an operation database;

[0159] c. Real-time detect the temperature Tc and compare it with the adjacent continuous n groups of data in the buffer. When there is an obvious fluctuation in a limited continuous manner, it is judged to be caused by a temporary event, such as the opening and closing of the machine room door, etc. After the system detects the disappearance of the fluctuation, it can directly restore the settings such as the fan speed R and the input L of the cold source before the fluctuation, improve the system response speed, and reduce excessive cooling and temperature fluctuation.

[0160] 8. As Figure 5 shown, when the difference between the air-conditioning set temperature value Ts and the temperature Tc in the machine room exceeds the allowable fluctuation value t:

[0161] a. Ts - Tc ≥ t, the temperature in the machine room is significantly lower than the set value of the air-conditioning terminal unit. Reduce the cooling capacity and air volume input to the minimum set opening degree at a rate of 20% and 10 - 15 s per time. After adjusting to the minimum opening degree, maintain it for more than two machine room air circulation cycles. If Ts - Tc ≥ t still exists, completely close the cold source L (such as water valve, fluorine pump or compressor, etc.).

[0162] b. Ts - Tc ≤ -t, there is obvious overheating in the machine room. At this time, step by step increase the opening degree of the cold source (such as water valve, fluorine pump or compressor, etc.) to the maximum within one machine room air circulation cycle, and at the same time synchronously adjust the fan speed to the speed limit R maxRapidly increase the cooling input L to cool the computer room. Adjust to the maximum opening and maintain at least two computer room air circulation cycles. If Ts-Tc≤-t still exists, simultaneously issue alarm messages on-site and in the network management system to prompt maintenance personnel to intervene promptly.

[0163] Enter the air conditioning terminal unit control system to set the limits, adjustment range, and adjustment cycle for the fan and cooling. Initially, set the adjustment range to 5% for the minimum cooling source value, 20% for the maximum fan value, and the adjustment cycle to 15 seconds.

[0164] After the air conditioning terminal unit has been running for more than 10 minutes and the temperature in the computer room has reached a relatively stable level, the temperature is measured at different locations in the computer room. Based on the difference between the measured temperature and the set temperature, the adjustment range and adjustment cycle of the air conditioning terminal unit are adjusted accordingly until the difference between the fixed temperature value in the computer room and the set value of the air conditioning terminal unit is less than 2℃.
