[0058] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a control system provided in an embodiment of this application. Figure 1 As shown in the embodiment of this application, the control system includes an air conditioning system 10 and a control device 20. The air conditioning system 10 and the control device 20 are communicatively connected. This communication connection can be a wired communication connection or a wireless communication connection.

[0059] In one embodiment of this application, the control system may further include a data acquisition device 30. The data acquisition device 30 is communicatively connected to the air conditioning system 10 and the control device 20, respectively.

[0060] In practical applications, the air conditioning system 10 specifically refers to the main control room air conditioning system in a nuclear power plant. This main control room air conditioning system is the ventilation system for the main control room and electrical equipment room, and performs the following functions: maintaining the temperature and humidity in each room (i.e., the main control room and electrical equipment room) within the prescribed limits to meet the requirements of equipment operation and long-term personnel stay.

[0061] Please see Figure 2 , Figure 2 This is a schematic diagram of the specific structure of the air conditioning system 10. For example... Figure 2 As shown, the air conditioning system 10 includes a filter 11, an electric heater 12, a coil 13, a circulating water pump 14, an electric valve 15, an electric humidifier 16, a circulating fan 17, and a check valve 18.

[0062] In practical applications, the working process of the air conditioning system 10 is as follows: fresh air (i.e., outdoor fresh air) is obtained from the area where the air conditioning system 10 is located, filtered by the filter 11, mixed with return air (i.e., air drawn out from each enclosed space in the area where the air conditioning system 10 is located), and then filtered again by the filter 11, heated by the electric heater 12, cooled by the coil 13 and the circulating water pump 14, humidified by the electric humidifier 16, and then delivered to each enclosed space by the circulating fan. Each enclosed space refers to the aforementioned main control room and at least one electrical equipment room.

[0063] Electric valve 15 is used to control the water flow rate in the circulating water pump.

[0064] In this embodiment, the control device 20 is used to acquire environmental information of the area where the air conditioning system 10 is located, first device information of the circulating fan 17, and second device information of the circulating water pump 14. Based on the environmental information, the first device information, and the second device information, it determines the target air supply volume, target return air volume, target air supply temperature, and target water flow rate of the circulating water pump for each enclosed space in the area. Finally, it controls the circulating fan 17 and the circulating water pump 14 in the air conditioning system 10 according to the target air supply volume, target return air volume, target air supply temperature, and target water flow rate of each enclosed space. The control device 20 may be a microcontroller unit (MCU).

[0065] The area where the air conditioning system is located refers to the area where the main control room and electrical equipment room of the nuclear power plant are located.

[0066] Environmental information includes, but is not limited to, the outdoor temperature of the area where the air conditioning system 10 is located and the indoor temperature of each enclosed space. The first equipment information includes, but is not limited to, the total pressure, total air volume, capacity coefficient and working efficiency of the circulating fan 17; the second equipment information includes, but is not limited to, the total head, water flow rate, working efficiency of the circulating water pump 14 and the density of water in the circulating water pump 14.

[0067] It should be noted that the total pressure of the circulating fan 17 consists of the static pressure of the circulating fan 7 and the dynamic pressure of the circulating fan 17. The static pressure of the circulating fan 17 refers to the pressure generated by the irregular movement of air molecules impacting the pipe wall of the circulating fan; the dynamic pressure of the circulating fan 17 refers to the pressure generated when air flows.

[0068] Total head refers to the energy per unit weight of fluid.

[0069] In another embodiment of this application, the control device 20 can obtain the above-mentioned environmental information, the first device information of the circulating fan 17 in the air conditioning system 10 and the second device information of the circulating water pump 14 through the acquisition device 30.

[0070] In another embodiment of this application, the control device 20 can determine the control strategy for the air conditioning system 10 based on the target air supply volume, target return air volume, target air supply temperature and target water flow rate of the circulating water pump for each of the above-mentioned enclosed spaces, and send the control strategy to the air conditioning system 10.

[0071] Based on this, after receiving the above control strategy, the air conditioning system 10 can control the circulating fan 17 and the circulating water pump 14 according to the control strategy.

[0072] Please see Figure 3 , Figure 3 This is a flowchart illustrating the implementation of a device control method according to an embodiment of this application. In this embodiment, the device control method is executed by a control device.

[0073] like Figure 3 As shown, an embodiment of the device control method provided in this application may include S101 to S103, which are described in detail below:

[0074] In S101, environmental information of the area where the air conditioning system is located, first equipment information of the circulating fan in the air conditioning system, and second equipment information of the circulating water pump in the air conditioning system are obtained.

[0075] In this embodiment of the application, when the control device detects a control request, it can obtain environmental information of the area where the air conditioning system is located, first equipment information of the circulating fan in the air conditioning system, and second equipment information of the circulating water pump in the air conditioning system.

[0076] It should be noted that the control device can detect a control request by detecting that the user has triggered a preset operation on the control device. The preset operation can be determined according to actual needs and is not limited here. For example, the preset operation could be clicking a preset control; that is, if the control device detects that the user clicks a preset control on the control device, it considers that a preset operation has been detected, i.e., a control request has been detected. Of course, the preset operation can also be a time-triggered operation. The control device can be configured with a corresponding workflow during operation, which includes trigger nodes for multiple key events, including control events. In this case, if the control device detects that the trigger node associated with the control event has been reached, it executes operations S101 to S103 to perform control operations on the circulating fan and circulating water pump in the air conditioning system.

[0077] In one implementation of this application, the control device can obtain in real time environmental information of the area where the air conditioning system is located, first equipment information of the circulating fan in the air conditioning system, and second equipment information of the circulating water pump in the air conditioning system through a data acquisition device connected to it.

[0078] The environmental information includes, but is not limited to, the outdoor temperature of the area where the air conditioning system is located and the indoor temperature of each enclosed space. The first equipment information includes, but is not limited to, the total pressure, total air volume, capacity coefficient, and operating efficiency of the circulating fan. The second equipment information includes, but is not limited to, the total head provided by the circulating water pump, the water flow rate, the operating efficiency of the circulating water pump, and the density of the water in the circulating water pump.

[0079] The total air volume of the circulating fan is the total air supply volume.

[0080] Based on this, the data acquisition equipment may include temperature sensors and data acquisition devices. The temperature sensors are used to collect the indoor temperature of each enclosed space and the outdoor temperature of the area where the air conditioning system is located. The data acquisition devices are used to collect the first equipment information of the circulating fan and the second equipment information of the circulating water pump in the air conditioning system. The indoor temperature of each enclosed space is the return air temperature of that space, and the outdoor temperature of the area where the air conditioning system is located is the fresh air temperature, i.e., the outdoor air temperature.

[0081] It should be noted that the outdoor temperature of the area where the air conditioning system is located is the same as the outdoor temperature of each enclosed space.

[0082] Understandably, the control equipment can obtain the indoor temperature of each enclosed space and the outdoor temperature of the area where the air conditioning system is located through temperature sensors, and obtain the first equipment information of the circulating fan and the second equipment information of the circulating water pump in the air conditioning system through data acquisition devices.

[0083] In S102, based on the environmental information, the first device information, and the second device information, the target air supply volume, target return air volume, target air supply temperature, and target water flow rate of the circulating water pump for each enclosed space in the region are determined.

[0084] In this embodiment of the application, after obtaining the above-mentioned environmental information, the above-mentioned first device information and the above-mentioned second device information, the control device can calculate the energy consumption of the circulating fan based on the first device information and the environmental information, calculate the energy consumption of the circulating water pump based on the second device information and the environmental information, and determine the target air supply volume, target return air volume, target air supply temperature and target water flow rate of the circulating water pump for each enclosed space in the area where the air conditioning system is located based on the energy consumption of the circulating fan and the energy consumption of the circulating water pump.

[0085] In one embodiment of this application, in order to improve the energy efficiency of the air conditioning system and reduce the energy consumption of the circulating fan and circulating water pump, the control device can specifically be configured as follows: Figure 4 S201 to S203, as shown, determine the target supply air volume, target return air volume, target supply air temperature, and target water flow rate of the circulating water pump for each enclosed space in the area where the air conditioning system is located, as detailed below:

[0086] In S201, based on the environmental information, the first device information, and the second device information, an objective function is constructed to establish the relationship between the air supply volume, return air volume, air supply temperature, and water flow rate of the circulating water pump in each enclosed space, and the equipment energy consumption of the air conditioning system.

[0087] In S202, the objective function is solved according to the set constraints to obtain the minimum energy consumption of the device.

[0088] It should be noted that, in this embodiment, the equipment energy consumption of the air conditioning system is obtained by a preset formula based on the first equipment energy consumption of the circulating fan and the second energy consumption of the circulating water pump, and the first energy consumption of the circulating fan can be determined by the total air volume and total pressure of the circulating fan.

[0089] Based on this, in one embodiment of this application, the control device constructs the device energy consumption according to a preset formula, and the preset formula for describing the objective function is as follows:

[0090]

[0091] Where Z represents the energy consumption of the air conditioning system at time t, and N t This represents the first energy consumption of the circulating fan at time t. This represents the second energy consumption of the circulating water pump at time t. Pa represents the total air volume of the circulating fan at time t, and K represents the total pressure of the circulating fan. Nη represents the capacity coefficient of the circulating fan. w This indicates the operating efficiency of the circulating fan. This represents the total head provided by the circulating water pump at time t. Let ρ represent the water flow rate provided by the circulating water pump at time t, ρ represent the density of water in the circulating water pump, g represent the acceleration due to gravity, and η represent the acceleration due to gravity. p This indicates the operating efficiency of the circulating water pump.

[0092] Meanwhile, in order to ensure that the indoor temperature of each enclosed space in the area where the air conditioning system is located meets the requirements, and that the indoor temperature of each enclosed space is not only related to the supply air temperature of that enclosed space, but also to the supply air volume of that enclosed space, and that due to the limitations of the overall structure of the air conditioning system, the total air volume of the circulating fan needs to be kept within a certain range, and that the indoor pressure of each enclosed space needs to be higher than the pressure at the inlet and outlet between the air conditioning system and that enclosed space, the constraints of the above-mentioned preset formula, i.e. the objective function, may include, but are not limited to: the first constraint, the second constraint, and the third constraint.

[0093] The first constraint is determined by the indoor temperature and set temperature of each enclosed space; the second constraint is determined by the return air volume and supply air volume of each enclosed space; and the third constraint is determined by the total air volume and fresh air volume. The return air volume of each enclosed space refers to the air volume extracted by the circulating fan from each enclosed space. The fresh air volume refers to the amount of fresh outdoor air in the area where the air conditioning system is located, excluding the enclosed spaces.

[0094] In some possible embodiments, the constraints of the objective function may further include a fourth constraint, a fifth constraint, and a sixth constraint. The fourth constraint is determined by the supply air volume of each enclosed space, the fifth constraint is determined by the return air volume of each enclosed space, and the sixth constraint is determined by the total air volume of the circulating fan.

[0095] Based on this, in one embodiment of this application, the control device can describe the constraints of the above objective function using the following formula:

[0096]

[0097] in, This represents the indoor temperature of the i-th enclosed space in the area where the air conditioning system is located at time t. Let represent the set temperature of the i-th enclosed space at time t, and ΔT represent the set temperature difference of the i-th enclosed space at time t. This represents the total air volume of the circulating fan at time t. This represents the air supply volume of the i-th enclosed space at time t. Let Q represent the return air volume of the i-th enclosed space at time t.w,min Q represents the lower limit of the total air volume of the circulating fan. w,max Q represents the upper limit of the total air volume of the circulating fan. w,i,min Q represents the lower limit of the air supply volume for the i-th enclosed space. w,i,max Q represents the upper limit of the air supply volume for the i-th enclosed space. cir,i,min Q represents the lower limit of the return air volume in the i-th enclosed space. cir,i,max This represents the upper limit of the return air volume in the i-th enclosed space. This represents the fresh air volume of the area where the air conditioning system is located at time t, and a represents the scaling factor.

[0098] It should be noted that the scaling factor 'a' is used to describe the ratio of the fresh air volume of the area where the air conditioning system is located at time t to the total air volume of the circulating fan at time t, and 'a' ≥ 10%.

[0099] Based on this, the control device can solve the objective function based on the above constraints to obtain the minimum energy consumption of the device.

[0100] In one embodiment of this application, the total pressure of the circulating fan includes static pressure and dynamic pressure. The first equipment information of the circulating fan may also include a first wind speed outside the circulating fan duct, a second wind speed inside the circulating fan duct, the duct radius of the circulating fan, and the duct length. Therefore, the control device can be specifically controlled through, as shown in... Figure 5 The total pressure of the circulating fan is calculated using S301 to S303, as detailed below:

[0101] In S301, the dynamic pressure is calculated based on the first wind speed, the pipe radius, and the total air volume.

[0102] In S302, the static pressure is calculated based on the pipe radius, the pipe length, and the second wind speed.

[0103] In S303, the dynamic pressure and the static pressure are summed to obtain the total pressure.

[0104] In this embodiment, the control device can specifically calculate the dynamic pressure of the circulating fan according to the following formula:

[0105]

[0106] Among them, P d The value represents the dynamic pressure of the circulating fan, and υ represents the first air velocity. The value represents the total air volume of the circulating fan at time t, and r represents the duct radius.

[0107] In this embodiment, the control device can specifically calculate the static pressure of the circulating fan according to the following formula:

[0108]

[0109] Among them, P s ν represents the dynamic pressure of the circulating fan, λ represents the friction resistance coefficient, ν represents the second wind speed, ρ represents the air density, L represents the pipe length, and D represents the pipe diameter.

[0110] Based on this, the control equipment can determine the total pressure of the circulating fan as the sum of the dynamic pressure and static pressure of the circulating fan calculated above.

[0111] In another embodiment of this application, for any enclosed space where an air conditioning system is located, the control device can, as shown in the example... Figure 6 The calculations S401 to S403 shown below obtain the indoor temperature of the enclosed space at time t, as detailed below:

[0112] In S401, the time difference between the current time and the historical time is calculated, where the historical time is the previous time adjacent to the current time.

[0113] In S402, the outdoor temperature of the enclosed space at the historical time, the historical air supply temperature at the historical time, the indoor temperature of the enclosed space at the historical time, the thermal resistance of the enclosed space, the first specific heat capacity of the air in the enclosed space, the second specific heat capacity of the wind, and the heat dissipation and power of the equipment in the enclosed space are obtained.

[0114] In S403, the indoor temperature of the enclosed space is calculated based on the outdoor temperature of the enclosed space at the historical time, the historical air supply temperature, the indoor temperature of the enclosed space at the historical time, the time difference, the thermal resistance, the first specific heat capacity, the second specific heat capacity, the heat dissipation of the equipment, and the power of the equipment.

[0115] It should be noted that the current time refers to the moment when the control device receives the control request. In this embodiment, the current time specifically refers to time t. Therefore, the historical time can be time t-1.

[0116] In this embodiment, the thermal resistance of each enclosed space specifically refers to the ratio between the temperature difference between the enclosed space and the inner and outer walls of the outside, and the inner and outer walls of other enclosed spaces, and the power of the heat source (such as various devices in operation) of the enclosed space.

[0117] The heat dissipation of equipment in each enclosed space specifically refers to the sum of the heat dissipation of all the various devices in that enclosed space. The heat dissipation of each device can be determined by its power rating.

[0118] In this embodiment, the control device can specifically calculate the indoor temperature of the i-th enclosed space at time t using the following formula:

[0119]

[0120] in, This represents the indoor temperature of the i-th enclosed space at time t. Let represent the indoor temperature of the i-th enclosed space at a historical time (i.e., time t-1). This represents the air volume supplied to the i-th enclosed space at a given historical moment. Historical air supply temperature at a historical moment. q represents the outdoor temperature at a historical moment. i Let a represent the heat dissipation of the device within the i-th enclosed space. i b i c i and d i Both are constants, where τ represents the time difference between time t and a historical time, and R... i Let c represent the thermal resistance of the i-th enclosed space. w C represents the second specific heat capacity of wind. i This represents the first specific heat capacity of the air in the i-th enclosed space.

[0121] It should be noted that the outdoor temperature at any given moment is the same as the fresh air temperature at that moment.

[0122] In another embodiment of this application, combined with Figure 2 The second piece of equipment information for the circulating water pump includes water flow rate; a coil is installed between the circulating fan and the circulating water pump, the coil having a cold end and a hot end. The cold end of the coil has a water inlet and an outlet, and the hot end has an air inlet and an air outlet. Therefore, the control equipment can be specifically controlled through, for example... Figure 7 The target supply air temperature is calculated using S501 to S502, as detailed below:

[0123] In S501, the air inlet temperature, the third specific heat capacity of the chilled water corresponding to the cold end, the fourth specific heat capacity of the hot air corresponding to the hot end, the first density of the chilled water corresponding to the cold end, and the second density of the hot air are obtained.

[0124] In S502, the target air supply temperature is calculated based on the set temperature difference between the water inlet and the water outlet, the total air volume, the water flow rate, the air inlet temperature, the third specific heat capacity, the fourth specific heat capacity, the first density, and the second density.

[0125] In this embodiment, the coil is also referred to as an air-water heat exchanger.

[0126] Taking summer as an example, in order to reduce the ventilation temperature, heat exchange is required, involving the exchange of heat between the chilled water at the cold end of the coil and the air supply. Based on this, the control equipment can calculate the target supply air temperature using the following formula:

[0127]

[0128] in, This indicates the heat load from ventilation and chilled water exchange. T represents the water flow rate provided by the circulating water pump at time t. c This indicates the set temperature difference between the inlet and outlet of the cold end of the coil. This represents the total air volume of the circulating fan at time t. This indicates the inlet air temperature at time t at the hot end of the coil. c represents the supply air temperature at the hot end outlet of the coil at time t. c c represents the third specific heat capacity of the chilled water corresponding to the cold end of the coil. w ρ represents the fourth specific heat capacity of the hot air corresponding to the hot end of the coil. c ρ represents the first density of the chilled water corresponding to the cold end of the coil. w This indicates the second density of the hot air corresponding to the hot end of the coil.

[0129] It should be noted that the target supply air temperature is the supply air temperature at time t.

[0130] The set temperature difference between the inlet and outlet of the cold end of the coil is usually set to 5 degrees Celsius. Specifically, the temperature of the cold end inlet of the coil can be set to 7 degrees Celsius, and the temperature of the cold end outlet of the coil can be set to 12 degrees Celsius.

[0131] The air inlet temperature at time t of the hot end of the coil can be determined based on the fresh air temperature (i.e., outdoor temperature) and the return air temperature (i.e., indoor temperature) of each enclosed space at time t.

[0132] Specifically, the inlet air temperature at time t of the hot end of the coil can be calculated using the following formula:

[0133]

[0134] in, This represents the total air volume of the circulating fan at time t. This represents the fresh air volume at time t. Let represent the return air volume of the i-th enclosed space at time t. This indicates the inlet air temperature at time t at the hot end of the coil. This represents the fresh air temperature at time t. Let represent the return air temperature of the i-th enclosed space at time t. This represents the outdoor temperature at time t. Let represent the indoor temperature of the i-th enclosed space at time t, and ∑(·) represent the summation function.

[0135] It should be noted that the return air temperature of the i-th enclosed space at time t is the same as the indoor temperature of that enclosed space at time t.

[0136] Combination Figure 2 The cold end of the coil is connected to the circulating water pump, and the hot end of the coil is connected to the circulating fan. Therefore, the chilled water corresponding to the cold end of the coil is the water stored in the circulating water pump, and the hot air corresponding to the hot end of the coil is the air blown out by the circulating fan. In other words, the third specific heat capacity of the chilled water corresponding to the cold end of the coil is the specific heat capacity of the water in the circulating water pump, the fourth specific heat capacity of the hot air corresponding to the hot end of the coil is the specific heat capacity of the air blown out by the circulating fan, the first density of the chilled water corresponding to the cold end of the coil is the density of the water in the circulating water pump, and the second density of the hot air corresponding to the hot end of the coil is the density of the air blown out by the circulating fan.

[0137] In yet another embodiment of this application, combined with Figure 2 Since the air supply to each enclosed space uses a mixture of fresh and return air, the total air volume of the circulating fan at time t can be calculated using the following formula:

[0138]

[0139] in, This represents the total air volume of the circulating fan at time t. This represents the fresh air volume at time t. Let represent the return air volume of the i-th enclosed space at time t, and ∑(·) represent the summation function.

[0140] In another embodiment of this application, since the area where the air conditioning system is located includes at least one enclosed space, the control device can specifically calculate the total air volume of the circulating fan at time t using the following formula:

[0141]

[0142] in, This represents the total air volume of the circulating fan at time t. Let represent the air supply volume of the i-th enclosed space at time t, and ∑(·) represent the summation function.

[0143] In another embodiment of this application, the total head provided by the circulating water pump at time t can be calculated according to the following formula:

[0144]

[0145] in, This represents the total head provided by the circulating water pump at time t. Let α represent the water flow rate provided by the circulating water pump at time t, where α, β, and γ are all constants.

[0146] In S203, the target air supply volume, the target return air volume, the target air supply temperature, and the target water flow rate are determined based on the minimum value.

[0147] In this embodiment, in conjunction with S202, the control device can determine the target air supply volume, target return air volume, target air supply temperature, and target water flow rate of the circulating water pump for each enclosed space based on the calculated minimum energy consumption of the equipment, the set constraints, and the objective function.

[0148] It should be noted that the target supply air volume is the supply air volume at time t, the target return air volume is the return air volume at time t, the target supply air temperature is the supply air temperature at time t, and the target water flow rate is the water flow rate at time t.

[0149] The target supply air volume for each enclosed space can be the same or different; this is not restricted. The target return air volume for each enclosed space can be the same or different; this is not restricted. The target supply air temperature for each enclosed space can be the same or different; this is not restricted.

[0150] In S103, the circulating fan and the circulating water pump are controlled according to the target air supply volume, the target return air volume, the target air supply temperature, and the target water flow rate.

[0151] In this embodiment, since the supply air volume and return air volume are usually controlled by the circulating fan, the supply air temperature is usually controlled by the circulating fan and the circulating water pump, and the water flow rate is controlled by the circulating water pump, the control device can control the circulating fan based on the target supply air volume and target return air volume after obtaining the target supply air volume and target return air volume. For example, the circulating fan can extract the amount of fresh outdoor air based on the target supply air volume and extract the air volume in each enclosed space based on the target return air volume.

[0152] After obtaining the target water flow rate, the control equipment can control the electric valve used to control the water volume of the circulating water pump, so that the circulating water pump stores water at the target flow rate.

[0153] After obtaining the target supply air temperature, the control equipment can exchange heat between the hot air from the total air volume of the circulating fan and the chilled water from the circulating water pump at the target water flow rate through the coil, so that the final supply air temperature at the hot end outlet of the coil is the target supply air temperature.

[0154] As can be seen from the above, the device control method provided in this application obtains environmental information of the area where the air conditioning system is located, first device information of the circulating fan in the air conditioning system, and second device information of the circulating water pump in the air conditioning system; based on the environmental information, the first device information, and the second device information, it determines the target air supply volume, target return air volume, target air supply temperature, and target water flow rate of the circulating water pump for each enclosed space in the area; and controls the circulating fan and circulating water pump based on the target air supply volume, the target return air volume, the target air supply temperature, and the target water flow rate. Compared with the prior art, which requires adding and / or replacing other hardware devices in the air conditioning system, this method can control the circulating fan and circulating water pump in the air conditioning system through software. That is, it only needs to obtain the environmental information of the area where the air conditioning system is located, the first device information of the circulating fan, and the second device information of the circulating fan to achieve control of the circulating fan and circulating water pump, which is simple and reduces costs.

The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.
