[0123] In the above embodiments, water can be used as the heat transfer medium. Correspondingly, the heat transfer medium pump 220 can be a variable frequency water pump, and the heat transfer medium regulating valve 210 can be an electric two-way regulating valve.

[0124] Figure 1 In the shown embodiment, the control device includes a main controller 410, a blower controller 420, and a heat transfer medium controller 430, which are communicatively connected to each other. The blower controller 420 is used to control the opening degree of the air outlet 330, and the heat transfer medium controller 430 is used to control the flow rate of the heat transfer medium pump 220 and the on / off of the heat transfer medium regulating valve 210.

[0125] In some embodiments, the room temperature detection device 322 includes a plurality of temperature sensors disposed on the inner walls of the temperature control area 310.

[0126] In the above embodiments, the plurality of temperature sensors may be evenly distributed on the inner wall of the temperature control area 310, and the height is consistent with the installation position of the return air outlet.

[0127] In some embodiments, the air conditioning system further includes an interaction device 320. The interaction device 320 is communicatively connected to the control device and disposed within the temperature control area 310, and is configured to set the allowable range of the noise value and / or the allowable range of the temperature value of the temperature control area 310.

[0128] The interaction device 320 may adopt an air conditioner wired controller, and users in each temperature control area can independently set the allowable range of the noise value and the allowable range of the temperature value in the temperature control area where they are located.

[0129] In some embodiments, the air conditioning system further includes a return air duct 530. One end of the return air duct 530 is connected to the temperature control area 310, and the other end is connected to the air inlet 160.

[0130] Figure 1 In the illustrated embodiments, the air conditioning system further includes a fresh air duct 540 and an air supply duct 520. The return air duct 530 is connected to the fresh air duct 540 and supplies air to the air inlet 160 through the air supply duct 520. The fresh air and the return air jointly bear the cooling load in the temperature control area. The air conditioning system further includes an air inlet regulating valve 170 disposed upstream of the air inlet 160.

[0131] As Figure 1 shown, in some embodiments, the air conditioning system includes a plurality of air outlets 330 connected to a plurality of temperature control areas 310.

[0132] Some embodiments of the present disclosure also provide a control method for the foregoing air conditioning system, including: determining the operating mode of the air conditioner 100 according to the real-time value T0 of the first gas temperature, wherein, in different operating modes, the value range of the ratio k is different.

[0133] In the control method of the control system provided by the embodiments of the present disclosure, when refrigeration or heating is not required, or when only low-load refrigeration or heating is required, for example, during the transitional season, the operating mode with a corresponding ratio k can be determined according to the real-time value T0 of the first gas temperature at the air inlet 160. By changing the ratio k, the proportion of the gas flowing through the air inlet that exchanges heat with the heat exchanger is reduced, thereby reducing the pressure loss when the air flow passes through the coil and other structures of the heat exchanger, and realizing noise reduction and energy saving of the air conditioning system from the perspective of energy supply.

[0134] In some embodiments, determining the operating mode of the air conditioner 100 includes: if T0≥t1, setting the air conditioner 100 to the first operating mode; if t2≤T0<t1 is satisfied, setting the air conditioner 100 to the second operating mode; if T0≤t2 is satisfied, setting the air conditioner 100 to the third operating mode; where t1 and t2 represent the first temperature preset value and the second temperature preset value, and the ratio k of the air conditioner 100 in the first operating mode, the second operating mode, and the third operating mode decreases in turn.

[0135] The first temperature preset value t1 and the second temperature preset value t2 can be set according to conditions such as the temperature and humidity, season, etc. in which the air conditioning system is located. When the real-time value T0 of the first gas temperature at the air inlet 160 is relatively low, it indicates that the demand for cooling the air flow is also relatively small. At this time, the operating mode of the air conditioner 100 can be determined to be an operating mode with a lower ratio k to reduce noise.

[0136] In some embodiments, as Figure 2 shown, in the first operating mode, k = 1; as Figure 3 shown, in the second operating mode, 0<k<1; as Figure 4 shown, in the third operating mode, k = 0.

[0137] When the real-time value T0 of the first gas temperature at the air inlet 160 changes stepwise, it indicates that the cooling load of the air conditioning system may have changed suddenly. For example, it may be that a supply air outlet in a temperature-controlled area is opened or closed. At this time, it may be necessary to change the operating mode of the air conditioner 100 so that the cooling capacity of the air conditioner matches the cooling load.

[0138] In some embodiments, it is determined whether the real-time value T0 of the first gas temperature changes stepwise. If the real-time value T0 of the first gas temperature changes stepwise, the ratio k is changed.

[0139] In some embodiments, adjusting the ratio k includes: adjusting the flow area of the bypass channel B of the air conditioning system and / or the flow area of the heat exchanger 120.

[0140] In some embodiments, adjusting the flow area of the bypass channel B of the air conditioning system and / or the flow area of the heat exchanger 120 includes: adjusting the angle between the wind blocking part 131 pivotally connected to the heat exchanger 120 and the heat exchanger 120.

[0141] In the above embodiments, the angle between the wind blocking part pivotally connected to the heat exchanger 120 can be adjusted by driving the driving part, so as to change the ratio k and the operating mode of the air conditioner 100.

[0142] In some embodiments, for noise control in the temperature-controlled area, the control method further includes: if the first real-time value Lp of the noise value in at least one temperature-controlled area 310i If it exceeds the noise setting range, adjust the parameters of the first air conditioner so that the noise values of all temperature control areas 310 are within the noise setting range. The parameters of the first air conditioner include at least one of the following: the frequency of the blower 110 and the opening degree of the air outlet 330, where Lp i represents the first real-time value of the noise value of the i-th temperature control area 310.

[0143] In some embodiments, for temperature control of the temperature control area, the control method further includes: if the real-time value T of the room temperature in at least one temperature control area 310 i exceeds the temperature setting range, adjust the parameters of the second air conditioner so that the temperature values of all temperature control areas 310 are within the temperature setting range. The parameters of the second air conditioner include at least one of the following: the frequency of the blower 110, the flow rate of the heat exchange medium, and the opening degree of the air outlet 330, T i represents the real-time value of the temperature value of the i-th temperature control area 310.

[0144] In the control method in the above embodiments, the noise setting ranges of different temperature control areas may be the same or different, and the temperature setting ranges of different temperature control areas may be the same or different. In one control cycle, the operating mode of the air conditioner 100 can be determined first according to the real-time value T0 of the first gas temperature at the air inlet 160. After the air conditioner 100 operates stably in a certain operating mode for a period of time, then it is determined whether noise control and temperature control need to be performed on the temperature control area.

[0145] If the first real-time values Lp of the noise values of each temperature control area 310 i are all within the noise setting range and the real-time value T of the room temperature i is all within the temperature setting range, then reduce the frequency of the blower 110.

[0146] If there is a temperature control area that exceeds the noise setting range, enter the noise control process.

[0147] If there is a temperature control area that exceeds the temperature setting range, enter the temperature control process.

[0148] The noise control process in the control method of the air conditioning system will be further described below.

[0149] In some embodiments, if the first real-time value Lp of the noise value of at least one temperature control area 310 iWhen the noise exceeds the set range, adjusting the parameters of the first air conditioner includes: obtaining the number X of temperature control zones 310 where the first real-time value of the noise exceeds the noise set range and the number Y of temperature control zones 310 where the air outlets 330 are in the open state; if X = Y, adjusting the frequency of the fan 110; if X < Y, adjusting the opening degree of the air outlets 330 of the temperature control zones 310 where the first real-time value of the noise exceeds the noise set range.

[0150] If X = Y, it indicates that the first real-time value Lp of the noise i The number of temperature control zones 310 where the noise exceeds the noise set range is equal to the number of temperature control zones 310 where the air conditioner is turned on, indicating that the overall air volume of the air conditioning system is too large, resulting in excessive noise in all temperature control zones 310 where the air conditioner is turned on.

[0151] In some embodiments, if X = Y, adjusting the frequency of the fan 110 includes: if the difference between the first real-time value Lp of the noise in at least one temperature control zone 310 i and the noise upper limit value Lp of the same temperature control zone 310 imax is greater than the first noise preset value, reducing the frequency of the fan 110 by the first frequency preset value F1, where the noise upper limit value Lp imax represents the maximum allowable noise value in the i-th temperature control zone 310; if the difference between the first real-time value Lp of the noise in all temperature control zones 310 i and the noise upper limit value Lp of the same temperature control zone 310 imax is less than the first noise preset value, reducing the frequency of the fan 110 by the second frequency preset value F2, where F1 > F2.

[0152] In the above embodiments, the noise upper limit value Lp imax and the first noise preset value can be set according to the noise reduction requirements of the air conditioning system. For example, the first noise preset value can be set to 3 dB(A).

[0153] After the frequency of the fan 110 is reduced, due to the change of the intersection point of the fan performance curve and the pipeline characteristic curve, both the air volume and the air pressure decrease. According to the formula Lw = Lwc + 10log(QH 2 ), when the model of the fan 110 is determined, Lwc is a fixed value. It can be seen that the air volume and the air pressure decrease, and the noise of the fan 110 decreases. At this time, the noise control process can be ended and the process of determining the working mode of the air conditioner 100 can be returned.

[0154] In some embodiments, when X < Y, adjusting the opening degree of the air outlet 330 of the temperature control area 310 where the first real-time value of the noise value exceeds the noise setting range includes: reducing the opening degree of the air outlet 330 of the temperature control area 310 where the first real-time value of the noise value exceeds the noise setting range by a first preset opening value A1; obtaining, after a preset time interval Δt, the second real-time value Lp of the noise value of each temperature control area 310 i ’, where Lp i ’ represents the second real-time value of the noise value of the i-th temperature control area 310; obtaining the number X’ of temperature control areas 310 where the second real-time value of the noise value exceeds the noise setting range; if X’ < X, stop adjusting the first air conditioner parameter; if X’ ≥ X, adjust the frequency of the blower 110

[0155] In the above embodiments, when X’ < X, that is, when the number of temperature control areas 310 where the noise value after adjusting the opening degree of the air outlet 330 exceeds the noise setting range is smaller than the original number, it indicates that the method of reducing the opening degree of the air outlet 330 has a positive impact on noise control. At this time, the noise control process can be ended and the process of determining the working mode of the air conditioner 100 can be returned

[0156] In the above embodiments, when X’ ≥ X, that is, when the number of temperature control areas 310 where the noise value after adjusting the opening degree of the air outlet 330 exceeds the noise setting range is more or equal to the original number, it indicates that the method of reducing the opening degree of the air outlet 330 cannot play a positive role in noise control. Then, the frequency of the blower 110 is reduced. At this time, the method of adjusting the frequency of the blower 110 can refer to the method of adjusting the frequency of the blower 110 when X = Y. Because reducing the opening degree of the air outlet 330 of a single temperature control area 310 only reduces the air volume of the temperature control area 310 where the opening degree of the air outlet 330 has been reduced, and the total air volume remains unchanged, the air volume of other temperature control areas 310 where the opening degree of the air outlet 330 has not been adjusted will increase, which may cause the noise value to exceed the noise setting range. When any one of reducing the opening degree of the air outlet 330 or reducing the frequency of the blower 110 can play a positive role in noise reduction, the noise control process can be ended and the process of determining the working mode of the air conditioner 100 can be returned

[0157] The temperature control process in the control method of the air conditioning system will be further described below

[0158] In some embodiments, when the real-time value T of the room temperature of at least one temperature control area 310 i exceeds the temperature setting range, adjusting the second air conditioner parameter includes: obtaining the real-time value T1 of the second gas temperature; if T1 < Td i , then adjust the frequency of the blower 110; if T1 ≥ Td i, it is determined whether the opening degree of each air outlet 330 reaches the maximum value. If the opening degree of at least one air outlet 330 reaches the maximum value, the flow rate of the heat exchange medium is adjusted. If the opening degrees of all air outlets 330 do not reach the maximum value, the opening degree of the air outlet 330 in the temperature control area 310 where the real-time value of the room temperature exceeds the temperature setting range is adjusted; where Td i represents the dew point temperature of the i-th temperature control area 310.

[0159] In some embodiments, if T1 < Td i , adjusting the frequency of the blower 110 includes: increasing the frequency of the blower 110 by a third preset frequency value F3.

[0160] For the case of the air conditioning system in refrigeration, if T1 < Td i , increasing the frequency of the blower 110 can increase the total air supply volume, increase the air supply temperature, and prevent condensation in the temperature control area 310.

[0161] When the opening degree of the air outlet 330 has reached the maximum value, it indicates that the external environmental temperature is very hot at this time, and the cooling capacity provided by the refrigeration device 200 does not meet the cooling load requirements of each temperature control area 310. At this time, it is necessary to increase the flow rate of the heat exchange medium.

[0162] In some embodiments, if the opening degree of at least one air outlet 330 reaches the maximum value, adjusting the flow rate of the heat exchange medium includes: increasing the frequency of the heat exchange medium pump 220 that transports the heat exchange medium by a fourth preset frequency value F4.

[0163] In some embodiments, if the opening degrees of all air outlets 330 do not reach the maximum value, adjusting the opening degree of the air outlet 330 in the temperature control area 310 where the real-time value of the room temperature exceeds the temperature setting range includes: increasing the opening degree of the air outlet 330 in the temperature control area 310 where the real-time value of the room temperature exceeds the temperature setting range by a second preset opening value A2.

[0164] The adjustment of the air volume in the air supply channel 510 can be achieved by adjusting the opening degree of the air outlet 330 and the frequency of the blower 110, but the adjustment methods of the two are different.

[0165] Adjusting the opening degree of the air outlet 330 will increase the resistance of the pipeline where the air outlet 330 is located, resulting in the working point moving up, the air pressure of the pipeline where the air outlet 330 is located increasing, the air volume decreasing, the resistance conditions of each branch pipe section of the air supply channel 510 changing, and the air volume being redistributed, which may cause the air volume of the pipeline corresponding to other air outlets 330 to increase, and the noise value in some temperature control areas 310 to increase and exceed the noise setting range.

[0166] Reducing the frequency of the blower 110 will change the performance curve of the blower 110, causing the operating point to move downward, the total air supply pressure to decrease, and the total air supply volume to also decrease. At this time, there is a possibility that the most unfavorable pipeline has insufficient air pressure and there is not enough power to supply air to the air supply outlet of the most unfavorable pipeline, resulting in a sudden drop in the air supply volume of the most unfavorable pipeline. To meet the air supply volume requirement of the most unfavorable pipeline, the air inlet regulating valve 170 on the total air supply pipeline will be adjusted to increase the air pressure. While increasing the air pressure, the air volume will decrease again, which is likely to cause some temperature control areas 310 to trigger the low air supply temperature protection mechanism due to a significant decrease in the total air volume. The low air supply temperature protection mechanism is as follows: To prevent the air supply temperature from being lower than the dew point temperature Td of the temperature control area 310 i which causes condensation in the temperature control area 310. When the air supply temperature is too low, the blower frequency is increased to increase the air supply volume of the blower and raise the air supply temperature.

[0167] In the control method of the air conditioning system according to the embodiments of the present disclosure, noise control and temperature control can be carried out independently. By adjusting at least one of the frequency of the blower 110 and the opening degree of the air outlet 330, the noise value of each temperature control area can reach the noise control range. By adjusting the frequency of the blower 110, the flow rate of the heat exchange medium, and the opening degree of the air outlet 330, the temperature value of each temperature control area can reach the temperature setting range, which is beneficial to meeting the comfort requirements of personnel in multiple temperature control areas for noise and temperature.

[0168] In some embodiments, the control device described above can be implemented as a general-purpose processor, a programmable logic controller (Programmable Logic Controller, abbreviated as: PLC), a digital signal processor (Digital Signal Processor, abbreviated as: DSP), an application specific integrated circuit (Application Specific Integrated Circuit, abbreviated as: ASIC), a field programmable gate array (Field-Programmable Gate Array, abbreviated as: FPGA), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, or any suitable combination thereof for performing the functions described in the present disclosure.

[0169] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure and not to limit them; although the present disclosure has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that: the specific implementation manners of the present disclosure can still be modified or some technical features can be equivalently replaced, and they should all be covered by the scope of the technical solutions claimed in the present disclosure.
