Description of the Invention: [Technical Field of the Invention] The present invention relates to a flow control system for controlling the flow rate of a fluid flowing through a flow path. [Prior Art] In the case of such a flow control system, there is a system (for example, refer to Patent Documents 1 and 2) for controlling the flow of heat medium (cold hot water) and flow rate to the air conditioner. When constructing the air conditioning control system, the maximum amount of air conditioning load (maximum air conditioning load) for supplying the control air region from the air conditioner is measured. The device that can eliminate the maximum air conditioning load, for example, the selected flow control is required. A valve or the like controls the amount of hot and cold water supplied to the air conditioner by the heat source device, the air conditioner, and the heat source device. Here, if the ability to fit the maximum air conditioning load is selected as the design capability, there is a design capability that is lower than the required capacity when the performance check is performed after the air conditioning control system is constructed, or the control target area is used after the air conditioning control system is put into use. The air conditioning load is increased and is greater than the maximum air conditioning load at the time of design. Therefore, based on security considerations, the equipment typically selected has the greatest margin of margin than the required design capability. [Patent Document 1] Japanese Patent Laid-Open No. Hei 6-272935 (Patent Document) However, in the above-described conventional air conditioning control system, since the selected device 200941171 has a need There is a problem in terms of energy efficiency in terms of how much design capability has the greatest margin. For example, if the capacity of the flow control valve is margined, when the flow control valve is desired to perform the opening control, the maximum flow rate more than the design flow rate flows during full opening, resulting in waste of energy. Conventionally, there is no means to quantify the waste of energy, so it is impossible to judge whether or not energy efficiency problems occur, which hinders energy conservation. The present invention has been made to solve the above problems, and an object thereof is to provide a flow rate control system capable of determining whether or not energy efficiency problems occur in a quantitative manner and promoting energy saving. In order to achieve the above object, the flow control system of the present invention is provided with: a valve body for regulating the opening and closing amount of a flow path through which a fluid flows; and a flow memory means for storing a design flow rate for use, the design of the operation The flow rate is set to a value smaller than the flow rate of the fluid flowing through the flow path when the opening degree of the valve body is maximum; the actual flow rate measuring means is used to measure the actual flow rate of the fluid flowing through the flow path; and the flow rate calculation means is exceeded. The actual flow measured by the actual flow measurement means is compared with the design flow rate stored in the design flow memory means, and the actual flow rate exceeds the design flow period as the actual flow excess period, and the actual time is accumulated in each of the excess periods. The flow exceeds the excess of the design flow. According to the present invention, the actual flow rate of the fluid flowing through the pipeline can be measured, and the actual flow rate can exceed the excess of the design flow rate during each excess period in which the actual flow rate of the fluid flowing through the flow passage exceeds the design flow rate. In the present invention, by referring to the integrated value of the excess flow rate, it is possible to quantitatively know how much the system is applied to the design and to what extent it deviates from the design. 5 200941171 and the like. In addition, by analyzing the integrated value of the excess flow rate, it is possible to check to what extent the system wastes energy and check whether an abnormality has occurred. In the present invention, 'when the actual flow exceeds the design flow, the actual flow exceeds the design flow during the period when the actual flow exceeds the design flow' as the continuous excess flow, and the integrated value of the continuous excess flow exceeds the predetermined value. When the value is output, the alarm can be immediately confirmed, and the abnormal state exceeding the flow rate can be confirmed immediately, and the corresponding countermeasure can be quickly taken. Further, at this time, if an alarm of the output is received and the opening degree of the valve body is forcibly changed to the closing direction to reduce the flow rate of the fluid flowing through the flow path (for example, to the design flow rate), the abnormal state can be eliminated and energy can be saved. . Further, the flow control system of the present invention is not limited to the application of the air conditioning control system for controlling the flow rate of the heat medium supplied from the air conditioner as long as it is a system for controlling the flow rate of the fluid using the valve body. By applying the present invention to an air conditioning control system, when the air conditioning control system is used, it is possible to notify the waste of energy or the abnormal flow exceeding the flow rate, thereby avoiding the abnormal flow exceeding the flow rate and functioning as a protection air conditioning control system. Moreover, when applied to the air conditioning control system, the design flow rate for cold water and the design flow rate for hot water can be stored in advance in the design flow memory means for water use, and when the air conditioner is used to output cold air, the design flow rate for cold water is selected as the design flow rate. When (4) the air conditioner outputs the heating, the design flow rate of the hot water is selected as the design flow rate. Sometimes the design flow is different in the case of air-conditioning and heating. 'By setting the design flow rate to the design flow rate for cold water and the design flow rate for hot water, you can choose to monitor the excess flow in both air-conditioning and heating. , issue an alarm, respond. 200941171 According to the present invention, since the actual flow rate of the fluid flowing through the pipeline is measured 'and the actual flow rate of the fluid flowing through the pipeline exceeds the design flow rate, the actual flow rate exceeds the design flow exceeds the design flow rate, so Referring to the integrated value of the excess flow rate, it is quantitatively known how much the system is applied to the design, to what extent it deviates from the design, and the like. In addition, by analyzing the integrated value of the excess flow rate, it is possible to check to what extent the system wastes energy and check whether an abnormality has occurred. © Embodiments Hereinafter, the present invention will be described in detail based on the drawings. Fig. 1 is a configuration diagram showing an example of an air conditioning control system to which the flow control system of the present invention is applied. ❹ In Fig. 1, 1 is a heat source machine for generating hot and cold water, 2 is a pump for conveying hot and cold water generated by the heat source unit 1, 3 is a water tank for mixing hot and cold water from a plurality of heat source units, and 4 is a water supply line. 5 is an air conditioner that receives supply of hot and cold water from the water tank 3 to the water line 4, 6 is a return water line, and 7 is a hot and cold water that is exchanged in the air conditioner 5 and transported through the return water line 6. The returned return water tank '8 is a flow rate control valve for controlling the flow rate of the hot and cold water supplied from the water tank 3 to the air conditioner 5, and 9 is a gas supply temperature sensing for measuring the temperature of the air supply from the air conditioner 5 The air conditioner control device 11 is a coil of the air conditioner 5, and 12 is a blower. In the air conditioning control system, the hot and cold water that is pumped by the pump 2 and added by the heat source unit i is mixed in the water tank 3, supplied to the air conditioner 5 via the water line 4, and passed through the air conditioner 5 again. The return water pipeline “乍回回水7 200941171 and arrives at the return water tank 7' is again pumped by the pump 2, and circulates in the above path. For example, 'When the air conditioner is running, the cold source water is generated by the heat source machine 1 to make the cold water circulation” During operation, hot water is generated by the heat source unit 1 to circulate the hot water. The air conditioner 5 returns air (return air) and outside air from the control target area to the air conditioning control system by the coil 11 through which the hot and cold water passes. The mixed gas is cooled or heated, and the cooled or heated air is supplied as a supply air to the control target area via the blower 12. The air conditioner 5 is a single type air conditioner that uses the common coil U in the cooling operation and the heating operation. Fig. 2 is a view showing a main portion of the flow rate control valve $ of the air conditioning control system. The flow rate control valve 8 is provided with a line 13 for forming a flow path through which the hot and cold water flows through the air conditioner 5, and a fluid flow for flowing through the line 13. The valve body 14 that adjusts the opening and closing amount of the flow path, the motor 15 that drives the valve body 14, and the valve opening degree detector 16 and the display unit 17 that detect the actual opening degree of the valve body 14 as the valve opening degree 0 pv The communication interface 18, 19 as a communication medium between the air conditioning control device 10 or the monitoring device (not shown), the design flow storage 4 20 exceeds the flow rate integrated value storage unit 21, the abnormal threshold value storage unit 22, and the inside of the pipeline 13 The primary side pressure sensor 23 that detects the fluid pressure on the upstream side of the valve body 14 as the primary pressure ρι, and the secondary side pressure that detects the fluid pressure on the downstream side of the valve body 14 in the line 13 as the secondary pressure p2 The sensor 24 and the processing unit 25. The processing unit 25 includes a valve control unit 25A, an actual flow rate measuring unit 25B, a design flow rate exceeding notification unit 25C, a flow rate integration unit 25d, a continuous excess amount integration unit 25E, and a continuous excess flow rate integration. The value abnormality alarm unit 25F and the design flow rate reading unit 25G. The valve control unit 25A of the processing unit 25, the actual 200941171 flow rate measurement unit 25B, the design flow rate exceeding notification unit 25C, the excess flow rate integration unit 25D, and the continuous flow rate product. The calculation unit 25E, the continuous excess flow rate integrated value abnormality alarm unit 25F, and the design flow rate reading unit 25G can be realized by the processing function of the CPU according to the program. In addition, in this embodiment, the flow rate storage unit 2 is configured to store cold water. The design flow rate Qdc and the hot water design flow rate qdh are used as the design flow rate in operation. The design flow rate QDC for cold water and the design flow rate QDH for hot water are set to be smaller than the flow tube when the opening degree of the valve body 14 is the largest. The value of the fluid flow rate of the road ^ 3 ® . The design flow rate QDC for cold water and the design flow rate QDH for hot water are basically set to different values, but are also set to the same value as the case may be. In addition, the abnormal threshold value storage unit 22 The abnormal threshold value cth is stored for determining whether or not the threshold value is abnormal for the continuous excess flow rate integrated value △ ΔQC to be described later. Hereinafter, the characteristic processing operation of the flow rate control valve 8 will be described while interpolating the functions of the respective units of the processing unit 25. Further, in this example, the air-conditioning operation is performed, and the air-conditioning control device 1G notifies the flow rate control 8 of the mode signal for performing the cooling operation. In addition, in order to maintain the temperature of the control target area at the set temperature '#, the control setting command value 0 SP (the command value of the valve opening degree (0 to 1〇〇%)) is transmitted to the flow rate control valve 8 by the air conditioning control device. . In the flow rate control valve 8, the mode signal from the air-conditioning control unit 1A that the cold air is notified is transmitted to the design flow rate reading unit 25G via the communication interface 18. The design flow reading unit 25G receives the mode signal from the air conditioning control device that is notified of the cold air, and then reads the design flow QDC stored in the design flow storage unit such as cold water, and transmits it to the design flow rate qd to the design 9 200941171 » Ten flow rate exceeds the notification unit volume calculation unit 25Ε. 25C. The flow rate accumulating unit 25D exceeds the flow-value θ' continuously: the control setting command from the air-conditioning control device 1 is connected: the interface 18 is transmitted to the valve control unit 25-8. The valve control is configured such that the valve opening degree 0PV indicating the actual opening degree of the valve body 14 from the valve opening degree detector 16 coincides with the control setting command value (9) after receiving the control setting command from the air conditioning control device 1 A drive command is transmitted to the motor 15 to control the opening degree of the valve body 14. In the opening degree control of the valve body 14, the actual flow rate measuring unit 25 一次 sets the primary pressure 流体 of the fluid (cold water) from the primary side pressure domain detector 23, and the secondary pressure of the fluid from the secondary side pressure sensor 24 P2, and the valve opening degree 5»pv from the valve opening degree detector 16 as an input, based on these parameters, the actual flow rate QR of the fluid flowing through the line 13 is calculated as the measured value of the actual flow rate, and the actual flow rate QR is calculated. The transmission to the design flow rate exceeding notification unit 25C, the excess flow rate integration unit 25D, and the continuous flow rate integration unit 25E are continuously performed. The design flow rate exceeds the notification unit 25C, and compares the actual flow rate QR from the actual flow rate measuring unit 25b with the design flow rate QD (cold water set flow rate qdc) from the design flow rate reading unit 25G, when the actual flow rate QR exceeds the design flow rate QD. While the actual flow rate QR exceeds the design flow rate QD, the design flow rate exceeding notification signal is transmitted to the excess flow rate integrating unit 25D and the continuous excess flow rate integrating unit 25E. When the design flow rate exceeds the notification signal from the design flow rate exceeding notification unit 25C, the excess flow rate integrating unit 25D obtains the difference between the actual flow rate QR from the actual flow rate measuring unit 25B and the design flow rate 200941171' from the design flow rate reading unit 25G ( The actual flow rate QR exceeds the portion of the design flow rate QD), and the flow rate AQ is exceeded, and the excess flow rate AQ is integrated. The flow rate integration unit 25D exceeds the total period in which the design flow rate exceeds the notification signal, and the total flow rate AQ is accumulated. As a result, as shown in FIG. 3, the period in which the actual flow rate QR exceeds the design flow rate QD is taken as the excess flow period T of the actual flow rate, and the excess flow amount of the actual flow rate QR exceeds the design flow rate QD is accumulated for each of the excess time T, and each is obtained. The actual flow rate QR of the excess period T exceeds the integrated value of the excess amount Δ Q © of the design flow rate QD, and the integrated value of the excess flow rate at each time obtained by the excess flow rate integrating unit 25D is calculated as the integrated value of the excess flow rate. It is stored in the excess flow integrated value storage unit 21. Further, the integrated value Σ/XQ stored in the excess flow rate exceeding the flow rate integrated value storage unit 21 is displayed on the display unit 17, and is output to the air conditioning control device 10 and the monitoring device via the communication interface 19. When the design flow rate exceeds the notification signal from the design flow rate exceeding notification unit 25C, the continuous flow rate integration unit 25E calculates the actual flow rate QR from the actual flow rate measurement unit 25B and the design flow rate QD from the design flow rate reading unit 25G. The difference (the portion where the actual flow rate QR exceeds the design flow rate QD) is exceeded as the flow rate ΔQC, and the excess flow rate ΔQC is integrated. The flow rate integration unit 25E continuously exceeds the flow rate ΔQC for each period in which the design flow rate exceeds the notification signal. As a result, as shown in FIG. 4, the period in which the actual flow rate QR exceeds the design flow rate QD is taken as the excess flow period T of the actual flow rate, and the total flow rate QR exceeds the excess amount ΔQC of the design flow rate QD for each of the excess periods T. 11 200941171 Value, as the integrated value of the continuous excess flow rate. In this case, the accumulated value of the previous continuous excess flow rate is returned to zero every time the new excess period τ is entered, and the continuous integration of the flow rate from zero is started. The cumulative value of the continuous excess flow rate at each time obtained by the continuous excess "il quantity integrating unit 25E Σ Δ〇 (: 'transferred to the continuous excess flow rate integrated value abnormality alarm unit 25F. Continuously exceeds the flow rate integrated value abnormality alarm The portion 25F monitors the integrated value SAQC of the continuous excess flow rate from the continuous flow exceeding the flow rate integrating unit 25E, and when the speed exceeds the integrated value of the flow rate 2 Δ() (: exceeds the abnormal threshold Cth stored in the abnormal threshold value storage unit 22, The alarm is output, and the alarm from the continuous excess flow rate calculation value abnormality alarm unit 25F is transmitted to the display unit 17 and the valve control #25A, and is output to the air conditioning control device 1A and the monitoring device via the communication interface 19. The display unit 7 displays an abnormal state in which the flow rate is exceeded. The valve control unit 25A receives an alarm from the continuous excess flow rate integrated value abnormality alarm unit 25F, and obtains the actual flow rate qr and the design flow rate reading by the actual flow rate measuring unit. The design flow rate QD of the part 25G is forcibly changing the opening degree of the valve body to the closing direction, so that the actual flow rate QR becomes the design flow rate ❹ QD. The accumulated value of the excess flow rate Σ AQC is lower than the abnormal threshold value Cth', and the alarm output from the continuous excess flow rate integrated value abnormality alarm unit 25F is released. In this case, the control of the valve control unit 25A is returned to the air conditioning control device 10 The control setting command value Θ sp opening degree control.

Therefore, by referring to the integrated value of the excess flow rate, ΔQ' can quantitatively know how much the system is used in design, to what extent it deviates from the design, and so on. Further, by analyzing the integrated value Σ ΔQ exceeding the flow rate, it is possible to check to what extent the system wastes energy and check whether an abnormality has occurred. Further, according to the present embodiment, since the actual flow rate qR exceeds the design flow rate QD every time the actual flow rate qR exceeds the design flow rate QD, the actual flow rate QR exceeds the design flow rate QD by the excess amount ΔqC, as the continuous excess flow rate. When the integrated value of the continuous excess flow rate exceeds the abnormal threshold Cth, an alarm is output, and the content is displayed on the display unit I? and transmitted to the air-conditioning control device 10 and the monitoring device. Therefore, it is possible to immediately confirm that an abnormal state exceeding the flow rate has occurred, thereby enabling Take appropriate countermeasures quickly. Further, according to the present embodiment, when the integrated value Σ Δ QC exceeding the flow rate exceeds the abnormal threshold Cth, an alarm is output, and the opening degree of the valve body 14 ® is forcibly changed to the closing direction to reduce the flow rate of the fluid flowing through the line 13 By designing the flow rate QD, it is possible to eliminate abnormal conditions and to save energy. In addition, in the above description, the mode signal indicating that the air is sent from the air-conditioning control device 1 to the flow rate control valve 8 is premised, but when the air-conditioning control device 10 transmits the mode signal indicating that the heating is transmitted to the flow rate control valve 8, The same processing action is also performed. In this case, the design flow reading Deng 25G reads the hot water design flow rate QDH′ stored in the design flow storage unit 2 as the design flow rate QD, and transmits it to the design flow rate exceeding notification unit 25c, 13 200941171 to exceed the flow rate integrating unit 25D, The flow rate integration unit 25E is continuously exceeded. Further, in the above embodiment, the air conditioner 丨MQ device 10 transmits a notification to the flow control unit 8 as a cold (four) mode signal, "can detect the fluid temperature of the line π: according to the temperature of the flow control valve 8 Further, in the above embodiment, when the integrated value ς Δ QC of the continuous flow rate exceeds the abnormal threshold cth, the Jiang Guanlian is forced to change the opening degree of the valve body 14 to the "direction". The flow rate of the fluid enthalpy and the flow through the line 13 is reduced to the design flow rate QD, but it is not necessarily reduced to the design flow rate. For example, the opening degree of the valve body 14 can also be closed only by the predetermined opening metric. Further, in the above-described embodiment, the opening control of the wide body is performed by the inter-control unit ,, but the flow rate control may be performed based on the measurement of the inter-flow rate QR by the actual flow rate measuring unit 25B. At this time, the control command value is set. The heart "the command value of the valve opening degree is transmitted from the air-conditioning control device 1" with the command value of the flow rate (〇~1〇〇%), and the flow rate control is performed in accordance with the control setting command value "p". At this time, it is also possible to obtain the same effect by integrating the actual flow rate qr over the excess flow rate QD, and the same effect can be obtained. [Simplified Schematic] FIG. 1 is a view showing the air conditioning control of the flow control system to which the present invention is applied. Fig. 2 is a view showing a flow control portion used in the air conditioning control system. Fig. 3 is a view showing a case where the flow rate control unit exceeds the flow rate of 200941171 in the flow rate control unit. In the case where the flow rate control valve continuously exceeds the flow rate integrating unit, the flow rate is continuously exceeded.
