Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air conditioner and an energy-saving operation control method thereof, a computer device and a readable storage medium. Background Art

[0002] Special places such as computer rooms require 24-hour operation 365 days a year. The total heat load of the base station is affected by the power of the communication equipment and is linearly related. The real-time power of the base station communication equipment is related to the wireless utilization rate of the base station (i.e. the current number of user accesses / total number of accessible users). When the wireless utilization rate is high, the real-time power of the communication equipment is high. Therefore, the existing energy-saving method for base stations is to shut down some communication equipment channels when the number of user accesses is small. The energy efficiency curve of the variable frequency air conditioner with frequency is not a linear relationship, but a parabola. The highest energy efficiency point is in the medium and low frequency part. When the communication equipment channel opening rate is high, the indoor load increases, which will inevitably lead to an increase in the operating frequency and a decrease in energy efficiency.

[0003] In addition, in the prior art, regulation is usually performed according to peak and valley power consumption periods. Although this can save electricity bills, since the control is not based on energy efficiency, the energy saving effect may not actually be achieved. Summary of the invention

[0004] The first object of the present invention is to provide an energy-saving operation control method for an air conditioner. The control method is based on a communication device channel shutdown mode and takes energy efficiency as a control benchmark to ensure that the base station air conditioner maintains a high-efficiency operation range for a long time and reduces operating costs.

[0005] A second object of the present invention is to provide an air conditioner that implements the above energy-saving operation control method.

[0006] A third object of the present invention is to provide a computer device for implementing the above energy-saving operation control method.

[0007] A fourth object of the present invention is to provide a readable storage medium for implementing the above energy-saving operation control method.

[0008] To achieve the above-mentioned first purpose, the present invention provides an energy-saving operation control method for an air conditioner, including: obtaining the current communication device channel opening proportion A%, and determining whether A% is a low proportion; if so, calculating the energy efficiency corresponding to the air conditioner according to the current operating frequency of the compressor, and improving the internal fan windshield according to the energy efficiency; if not, further determining whether A% is a high proportion; if A% is not a high proportion, and when it is determined according to a preset relationship table that the next moment is a low proportion moment, reducing the operating frequency of the compressor according to the energy efficiency corresponding to the current operating frequency; if A% is a high proportion, improving the internal fan windshield and / or reducing the operating frequency of the compressor according to the energy efficiency corresponding to the current operating frequency.

[0009] It can be seen from the above scheme that the energy-saving operation control method of the present invention is based on the communication equipment channel shutdown mode, takes energy efficiency as the control benchmark, ensures that the base station air conditioner maintains in the high-efficiency operation range for a long time, and realizes energy-saving operation and reduces operating costs without increasing costs.

[0010] A preferred solution is that when A% is a low percentage, the step of improving the windshield of the inner fan according to the energy efficiency includes: determining whether the energy efficiency E1 corresponding to the current operating frequency is in the optimal energy efficiency range [E max1 , E max2 ]; if it is not in the optimal energy efficiency range, determine whether the inner fan windshield is at the highest windshield; if the inner fan windshield is not at the highest windshield, calculate the output cooling capacity corresponding to the current operating frequency, and determine whether the energy efficiency E2 corresponding to the output cooling capacity is greater than E1 after the inner fan windshield is raised to the preset gear; if E2>E1, raise the inner fan windshield to the preset gear; if E2≤E1, keep the current inner fan windshield unchanged.

[0011] It can be seen that if the energy efficiency is not in the optimal range, it means that the power consumption is large at this time. Under normal circumstances, raising the windshield of the inner fan can improve the energy efficiency. If the inner fan is not at the highest windshield at this time, the windshield can be raised to improve the energy efficiency and reduce the power consumption. By comparing E1 and E2, if E2>E1, since the output capacity is the same, it means that the power can be reduced after raising the windshield, that is, the power consumption is reduced, and the energy saving effect can be achieved. Therefore, the method of raising the windshield is adopted.

[0012] A preferred solution is that when A% is a medium proportion and it is determined that the next moment is a low proportion moment, the step of reducing the operating frequency of the compressor according to the energy efficiency corresponding to the current operating frequency includes: determining whether the energy efficiency corresponding to the current operating frequency f1 is less than E max2 And the current operating frequency f1 is in the range where the frequency increases and the energy consumption decreases; if the energy efficiency corresponding to the current operating frequency f1 is less than E max2 If the current operating frequency f1 is in the range where the frequency increases and the energy consumption decreases, the operating frequency of the compressor is reduced; the current indoor ambient temperature T0 is obtained, and the expected temperature rise △T of the indoor ambient temperature in the remaining time of the current period is calculated. s ; If T0+△T is satisfied s <T 上限 -△T 预设 When the condition is met, the operating frequency of the compressor will continue to decrease until T0+△T s ≥T 上限 -△T 预设 , where T 上限 is the preset upper limit temperature, △T 预设 is the preset temperature difference.

[0013] It can be seen that when the proportion is medium, the frequency usually runs at medium and high frequencies, so the energy efficiency may be at E max1 In the right range, when the room temperature does not exceed the upper limit, the frequency is slightly reduced to improve the air conditioning efficiency and reduce power consumption.

[0014] A further solution is that if the compressor frequency is reduced for the first time, and T0+△T is satisfied s ≥T 上限 If the condition is met, the operating frequency is restored to the initial operating frequency f1; if the compressor is reduced in frequency for the first time, when T 上限 -△T 预设 ≤T0+△T s ≤T 上限 When the condition is met, the current frequency is maintained.

[0015] It can be seen from this that if T0+△T is calculated after the first frequency reduction s ≥T 上限 , it indicates that it is not suitable for frequency reduction, so the operating frequency is restored to f1; if after the first frequency reduction, T 上限 -2≤T0+△T s ≤T 上限 , the current frequency is maintained.

[0016] A preferred solution is that when A% is a high percentage, the step of increasing the internal fan damper or reducing the operating frequency of the compressor according to the energy efficiency corresponding to the current operating frequency includes: determining whether the energy efficiency E1 corresponding to the current operating frequency is in the optimal energy efficiency range [E max1 , E max2 ]; if it is not in the optimal energy efficiency range, determine whether the inner fan windshield is at the highest windshield; if the inner fan windshield is not at the highest windshield, calculate the output cooling capacity corresponding to the current operating frequency, and determine whether the energy efficiency E2 corresponding to the output cooling capacity is greater than E1 after the inner fan windshield is raised to the preset gear; if E2>E1, raise the inner fan windshield to the preset gear; if E2≤E1, keep the current inner fan windshield unchanged, and determine whether the energy efficiency corresponding to the current operating frequency f1 is less than E max2 And the current operating frequency f1 is in the range where the frequency increases and the energy consumption decreases; if the energy efficiency corresponding to the current operating frequency f1 is less than E max2 If the current operating frequency f1 is in the range where the frequency increases and the energy consumption decreases, the operating frequency of the compressor is reduced; the current indoor ambient temperature T0 is obtained, and the expected temperature rise △T of the indoor ambient temperature in the remaining time of the current period is calculated. s ; If T0+△T is satisfied s <T 上限 -△T 预设 When the condition is met, the operating frequency of the compressor will continue to decrease until T0+△Ts ≥T 上限 -△T 预设 , where T 上限 is the preset upper limit temperature, △T 预设 is the preset temperature difference.

[0017] It can be seen that if E2≤E1, it means that the energy saving effect cannot be achieved by changing the windshield of the internal fan, and then further determine whether the current energy efficiency falls into E max2 The right interval, if in E max2 In the right range, the operating frequency of the compressor is reduced, so that when the usage ratio is high, efficiency can be improved and consumption can be reduced by raising the windshield or increasing the operating frequency.

[0018] A further solution is that if the compressor meets T0+△T after the first frequency reduction s ≥T 上限 If the condition is met, the operating frequency is restored to the initial operating frequency f1; if the compressor meets T 上限 -△T 预设 ≤T0+△T s ≤T 上限 When the condition is met, the current frequency is maintained.

[0019] It can be seen from this that if T0+△T is calculated after the first frequency reduction s ≥T 上限 , it indicates that it is not suitable for frequency reduction, so the operating frequency is restored to f1; if after the first frequency reduction, T 上限 -2≤T0+△T s ≤T 上限 , the current frequency is maintained.

[0020] A preferred solution is that the current communication device channel open proportion A% = the current communication device channel open number / the total communication device channel number * 100%; when A% ≤ 30%, it is a low proportion; when 30% < A% < 70%, it is a medium proportion; when A% ≥ 70%, it is a high proportion.

[0038] Air conditioner and energy-saving operation control method thereof embodiment:

[0039] The air conditioner in this embodiment is a base station air conditioner, and the air conditioner includes a processor, and the processor is used to implement the following energy-saving operation control method when executing the program stored in the memory.

[0040] See also Figure 1 , the energy-saving operation control method includes the following steps:

[0041] First, execute step S1 to obtain the current communication device channel opening ratio A%, and determine whether A% is a low ratio. The current communication device channel opening ratio A% = the number of current communication device channel openings / the total number of communication device channels*100%. In this embodiment, when A%≤30%, it is a low ratio; when 30%<A%<70%, it is a medium ratio; when A%≥70%, it is a high ratio.

[0042] If so, execute step S2 to calculate the energy efficiency corresponding to the air conditioner according to the current operating frequency of the compressor, and improve the windshield of the internal fan according to the energy efficiency.

[0043] If not, step S3 is executed to further determine whether A% is a high proportion.

[0044] If A% does not belong to a high proportion, and it is determined according to the preset relationship table that the next moment belongs to a low proportion moment, then step S4 is executed to reduce the operating frequency of the compressor according to the energy efficiency corresponding to the current operating frequency; Figure 6 The figure shows a relationship diagram of the number of communication equipment channel openings at various times according to a preset relationship table. The start time and end time of each proportion can be calculated in advance according to previous operation data.

[0045] If A% is a high percentage, step S5 is executed to increase the windshield of the internal fan and / or reduce the operating frequency of the compressor according to the energy efficiency corresponding to the current operating frequency.

[0046] The energy-saving operation control method is based on the communication equipment channel shutdown mode and takes energy efficiency as the control benchmark to ensure that the base station air conditioner maintains a high-efficiency operation range for a long time, thereby achieving energy-saving operation and reducing operating costs without increasing costs.

[0047] Specifically, see Figure 2 , the above step S2 comprises:

[0048] First, execute step S21 to obtain the current indoor ambient temperature T 内 , Outdoor ambient temperature T 外 、Inner fan windshield F 内 、External fan windshield F 外 and the current operating frequency f1 of the compressor, and judges whether the energy efficiency E1 corresponding to the current operating frequency f1 is in the optimal energy efficiency range [E max1 , E max2 ]. The energy efficiency E1 is obtained by substituting f1 into the fE curve under current conditions.

[0049] If it is not in the optimal energy efficiency range, then step S22 is executed to further determine whether the inner fan windshield F 内 Is it at the highest windshield?

[0050] If the inner fan windshield F 内 If the fan is not at the highest wind speed, then step S23 is executed to calculate the output cooling capacity Q1 corresponding to the current operating frequency f1, and to determine whether the fan is at the highest wind speed if the fan is raised to the preset gear position F 内2 After that, is the energy efficiency E2 corresponding to the output cooling capacity Q1 greater than E1? The output cooling capacity Q1 is obtained by substituting f1 into the fQ curve under the current conditions. The calculation method of energy efficiency E2 is: Substitute Q1 into F 内2 The corresponding fQ curve is obtained to obtain the corresponding f2, and then f2 is substituted into F 内2The corresponding fE curve is used to obtain E2. Preferably, the preset gear position F 内2 Add 1 to the current wind speed of the interior fan.

[0051] If E2>E1, then execute step S24 to raise the inner fan windshield to the preset gear position F. 内2 .

[0052] If E2≤E1, execute step S25 to keep the current windshield of the internal fan unchanged.

[0053] If the energy efficiency E1 is not in the optimal range [E max1 , E max2 ], it indicates that the power consumption is relatively large at this time. Under normal circumstances, raising the windshield of the inner fan can improve energy efficiency. If the inner fan is not at the highest windshield at this time, the windshield can be raised to improve energy efficiency and reduce power consumption. Figure 3 , the current operating frequency f1, the corresponding capacity Q1 (i.e. output cooling capacity) and energy efficiency E1 can be calculated through the frequency-capacity / energy efficiency curve corresponding to windshield 1 under the inner and outer rings at this time. E1 is not at the optimal energy efficiency. At this time, the windshield is raised to windshield 2. The current indoor load demand is still Q1. The frequency f2 corresponding to capacity Q1 is calculated through the frequency-capacity curve corresponding to windshield 2, and the energy efficiency E2 is calculated through the frequency-energy efficiency curve. By comparing E1 and E2, if E2>E1, since the output capacity is the same, it shows that the power can be reduced after raising the windshield, that is, the power consumption is reduced, and the energy saving effect can be achieved, so the way of raising the windshield is adopted.

[0054] See also Figure 4 , the above step S4 comprises:

[0055] First, execute step S41 to obtain the current indoor ambient temperature T 内 , Outdoor ambient temperature T 外 、Inner fan windshield F 内 、External fan windshield F 外 and the current operating frequency f1 of the compressor, and determines whether the energy efficiency E1 corresponding to the current operating frequency f1 is within E max2 The right interval, that is Figure 5 The right side of the middle red line, that is, judging whether the energy efficiency corresponding to the current operating frequency f1 is less than E max2 And the current operating frequency f1 is in the interval where the frequency increases and the energy consumption decreases.

[0056] If in E max2 The right interval, that is, the energy efficiency corresponding to the current operating frequency f1 is less than E max2 And the current operating frequency f1 is in the range where the frequency increases and the energy consumption decreases, that is, the energy efficiency E1 < the energy efficiency E max2 , and the frequency f1 corresponding to the energy efficiency E1> energy efficiency Emax2 The corresponding frequency f max2 , then execute step S42 to reduce the operating frequency aHz of the compressor. Preferably, the value of a is 2.

[0057] Next, execute step S43 to obtain the end time t1 of the current proportion period, the current indoor ambient temperature T0, and the indoor temperature change △T1 within △t1 time. Optionally, △t1 takes a value of 1 to 10 minutes, preferably, △t1 is 5 minutes; △T1 = T1-T0, T1 is the indoor ambient temperature after △t1 time. At the same time, calculate the expected temperature rise △T of the indoor ambient temperature in the remaining time of the current proportion period s , △T s =t1*△T1 / △t1. The end time t1 of the current proportion period can be calculated in advance based on the previous operation data to calculate the start time and end time of each proportion, such as Figure 6 As shown, the proportion of the next moment can be calculated based on the end moment of this proportion minus the current moment, so as to determine whether the next moment is a low proportion moment.

[0058] If T0+△T is satisfied s <T 上限 -△T 预设 If the condition is met, then return to step S42 and continue to reduce the operating frequency of the compressor aHz until T0+△T s ≥T 上限 -△T 预设 , where T 上限 is the preset upper limit temperature, △T 预设 is the preset temperature difference, optionally, T 上限 In the range of 30-40°C, preferably, T 上限 35℃, △T 预设 is 2℃.

[0059] If the compressor frequency is reduced for the first time, and T0+△T is met s ≥T 上限 When the condition is met, step S44 is executed to restore the operating frequency to the initial operating frequency f1.

[0060] If the compressor frequency is reduced for the first time, and T 上限 -△T 预设 ≤T0+△T s ≤T 上限 When the condition is met, step S45 is executed to maintain the current frequency operation.

[0061] When the ratio is medium, the frequency usually runs at medium and high frequency, so the energy efficiency may be E max1 In the right range, the frequency is slightly reduced when the room temperature does not exceed the upper limit, improving the air conditioning efficiency and reducing power consumption. Figure 7As shown, the current operating frequency f1 can be calculated by the corresponding frequency-capacity / energy efficiency curve of the inner ring, outer ring, and windshield at this time to obtain the corresponding capacity Q1 and energy efficiency E1. E1 is not at the optimal energy efficiency, and f1>f max1 , then reduce the compressor operating frequency aHz, the operating frequency is reduced, the capacity Q is reduced, and the indoor ambient temperature will inevitably rise when the load remains unchanged. Therefore, detect the end time t1 of the current proportion period, the current indoor ambient temperature T0, and the indoor temperature change △T1 within △t1 time, and calculate the expected temperature rise △T s =t1*△T1 / △t1, that is, the indoor temperature rise at the current f1-aHz frequency until the end of the current period. If T0+△T s <T 上限 -2, there is still room for further frequency reduction. If T0+△T calculated after the first frequency reduction s ≥T 上限 , it indicates that it is not suitable for frequency reduction, so the operating frequency is restored to f1; if after the first frequency reduction, T 上限 -2≤T0+△T s ≤T 上限 , the current frequency is maintained.

[0062] See also Figure 8 , the above step S5 comprises:

[0063] First, execute step S51 to obtain the current indoor ambient temperature T 内 , Outdoor ambient temperature T 外 、Inner fan windshield F 内 、External fan windshield F 外 and the current operating frequency f1 of the compressor, and built-in data to determine whether the energy efficiency E1 corresponding to the current operating frequency f1 is in the optimal energy efficiency range under the current conditions [E max1 , E max2 ].

[0064] If it is not in the optimal energy efficiency range, then step S52 is executed to further determine whether the inner fan windshield F 内 Is it at the highest windshield?

[0065] If the inner fan windshield F 内 If the fan is not at the highest wind speed, then step S53 is executed to calculate the output cooling capacity Q1 corresponding to the current operating frequency f1, and to determine whether the fan is at the preset wind speed F1. 内2 After that, the energy efficiency E2 corresponding to the output cooling capacity Q1 is greater than E1. The output cooling capacity Q1 and the energy efficiency E2 refer to step S23.

[0066] If E2>E1, step S54 is executed to raise the inner fan windshield to the first gear, that is, to raise the inner fan windshield to the preset gear position.

[0067] If E2≤E1, or the inner fan windshield F 内 If the wind speed is at the highest level, step S55 is executed to keep the current wind speed of the inner fan unchanged, indicating that the energy saving effect cannot be achieved by changing the wind speed of the inner fan at this time. Then, step S56 is executed to determine whether the energy efficiency E1 corresponding to the current operating frequency f1 is at E max2 The right interval, that is Figure 5 To the right of the middle red line.

[0068] If in E max2 In the right interval, step S57 is executed to reduce the operating frequency aHz of the compressor. Preferably, the value of a is 2.

[0069] Next, execute step S58 to obtain the end time t1 of the current proportion period, the current indoor ambient temperature T0, and the indoor temperature change △T1 within △t1 time. Optionally, △t1 takes a value of 1 to 10 minutes, preferably, △t1 is 5 minutes; △T1 = T1-T0, T1 is the indoor ambient temperature after △t1 time. At the same time, calculate the expected temperature rise △T of the indoor ambient temperature in the remaining time of the current proportion period s , △T s =t1*△T1 / △t1.

[0070] If T0+△T is satisfied s <T 上限 -△T 预设 If the condition is met, then return to step S57 and continue to reduce the operating frequency of the compressor until T0+△T s ≥T 上限 -△T 预设 , where T 上限 is the preset upper limit temperature, △T 预设 is the preset temperature difference.

[0071] If the compressor frequency is reduced for the first time, and T0+△T is met s ≥T 上限 When the condition is met, step S59 is executed to restore the operating frequency to the initial operating frequency f1.

[0072] If the compressor frequency is reduced for the first time, and T 上限 -△T 预设 ≤T0+△T s ≤T 上限 When the condition is met, step S60 is executed to maintain the current frequency operation.

[0073] It can be seen that if E2≤E1 or the inner fan windshield F 内 At the highest wind speed, it means that the energy saving effect cannot be achieved by changing the wind speed of the internal fan. Then we further judge whether the current energy efficiency falls into E max2 The right interval, if in Emax2 In the right section, the operating frequency of the compressor is reduced, so that when the ratio is high, efficiency can be improved by increasing the windshield or increasing the operating frequency. s ≥T 上限 , it indicates that it is not suitable for frequency reduction, so the operating frequency is restored to f1; if after the first frequency reduction, T 上限 -2≤T0+△T s ≤T 上限 , the current frequency is maintained.
