[0022] In order to be able to understand the features and technical content of the embodiments of the present disclosure in more detail, the implementation of the embodiments of the present disclosure is described in detail below in conjunction with the accompanying drawings. The accompanying drawings are for reference only and are not used to limit the embodiments of the present disclosure.

[0024] In the description and claims of the embodiments of the present disclosure, as well as in the accompanying drawings, the terms "first," "second," and the like are used to distinguish similar items and are not necessarily used to describe a particular order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate to describe the embodiments of the present disclosure herein. In addition, the terms "including," "having," and any variations thereof are intended to cover non-exclusive inclusions.

[0027] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0029] Large-scale projects requiring temperature regulation (such as commercial buildings, industrial parks, rail transit systems, and data centers) often require a combined Feng Shui system encompassing water, air conditioning, and ventilation. These systems often require a balance of energy conservation, stability, and comfort. However, these control requirements can conflict with each other. Due to practical constraints, there's no absolute control priority, nor is there a definitive logic for prioritizing ventilation over water or vice versa.

[0030] In related technologies, all control logic is fixed during initial commissioning, and subsequent adjustments are merely parameter adjustments, not logic adjustments. For example, if the initial control logic prioritizes wind over water, then water control can only be achieved by adjusting the threshold to reach that threshold, with no possibility of controlling water over wind. This demonstrates that related technologies are unable to flexibly and accurately coordinate control of the various systems within a feng shui integrated system, tailored to their specific needs.

[0031] As shown in FIG1 , an embodiment of the present disclosure provides a feng shui integrated system. The feng shui integrated system includes a water system, an air conditioning system, a ventilation system, and a linkage control device for the feng shui integrated system. The control device is communicatively connected to the water system, the air conditioning system, and the ventilation system, respectively. The control device can be a computer, terminal, server, or other device with computing capabilities.

[0032] In this disclosed embodiment, the principles of motion game theory are applied to the water system, the air conditioning system, and the ventilation system as participants in the game. The strategy space and benefit function of each system are defined. By playing the game with the water system, the air conditioning system, and the ventilation system, a new strategy space is determined for each system, allowing each system to operate according to the new strategy space.

[0033] In the disclosed embodiments, a policy space refers to the set of strategies or behaviors available to game participants. Here, each system's policy space includes at least one adjustable parameter of the system, and the policy space of each system is the set of adjustable parameters of that system. An adjustable parameter is a parameter of a system that can be changed in real time.

[0034] In the disclosed embodiments, the system's benefit function is used to quantify the benefits or profits obtained by the system under a specific policy space. The benefit function is used to evaluate the performance of the system under different policy spaces so as to make reasonable choices in the policy space.

[0035] Furthermore, the benefit function of each system includes an independent benefit function and a comprehensive benefit function.

[0036] In the embodiments of the present disclosure, an independent benefit function of a system generally refers to a system whose benefit function depends solely on the choices made in its own strategy space and is independent of the choices made in the strategy spaces of other systems. In other words, ideally, the benefit of a system is determined solely by its own behavior and is not affected by other systems. This assumption of an independent benefit function is reasonable in certain game scenarios, especially when there is no direct interaction or strategy dependency between systems. However, in most actual games, the strategy choices between systems often influence each other, so the benefit function may also involve the strategies of other systems.

[0037] In the disclosed embodiments, the system's comprehensive benefit function depends not only on the system's own strategy space selection, but is also influenced by multiple factors, including the strategy spaces of other systems, environmental factors, and resource constraints. When establishing a comprehensive benefit function, it is generally necessary to comprehensively consider multiple dimensions and assign appropriate weights to each. Establishing a comprehensive benefit function requires a deep understanding and analysis of the specific context of the game and the interactions between systems.

[0038] In the embodiment of the present disclosure, the water system includes multiple devices, such as a refrigeration host, a freezing pump, a cooling pump, a cooling tower, etc. The operation of these devices affects and restricts each other, providing sufficient cooling capacity for the terminal space to maintain the comfort and stability of the terminal environment. The energy-saving limitation of the water system's operation is mainly cooling capacity, that is, while providing the required cooling capacity, the total energy consumption of all devices is guaranteed to be the lowest. At the same time, there is a certain coupling relationship between the various devices. For different cooling requirements, control ranges, and boundary restrictions, the system has an optimal control parameter combination to minimize energy consumption, thereby making optimization at the strategy level feasible. For the water system, the adjustable parameters in the strategy space include at least one control parameter of each device and the start and stop status of each device. The control parameters of each device in the water system include the outlet water temperature T of the refrigeration host. ch , refrigeration pump flow Q ld , cooling pump flow Q lq and the cooling tower's approximation ΔT. At the same time, for equipment control, it is hoped that the adjustment step of its control parameters is as small as possible, and the start-stop switching is as few as possible to ensure control stability.

[0039] For example, a water system consists of n devices. Each device has an adjustable parameter, and each adjustable parameter has m1 possible values. The start and stop states of each device include on and off, with on being represented by 1 and off being represented by 0. The policy space of the water system is defined as Sr1. The expression of the policy space Sr1 of the water system is as follows:

[0040] In the above expression, x j represents the control parameter x of the jth device j,max represents the upper limit of the control parameter of the jth device, x j,min y represents the lower limit of the control parameter of the jth device, and δ1 represents the adjustment step of the control parameter of the jth device. j Indicates the start and stop status of the jth device, S w1 :(y=y0) means to keep the current start and stop state of the device, S w2 :(y=(1-y0)(1+y0)) indicates switching from the current start / stop state of the device to another start / stop state. y0 represents the current start / stop state of the device. When the start / stop state of the device is on, y0=1; when the start / stop state of the device is off, y0=0.

[0041] Furthermore, the current strategy space of the water system can be recorded as in, It is a vector composed of the current control parameters of each device in the water system. It is a vector composed of the current start and stop status of each device in the water system.

[0042] It should be noted that the control parameters of the water system's strategy space also include a cooling parameter, which will be affected by the choice of the ventilation system's strategy space. In other words, the ventilation system's strategy will affect the final benefits of the water system.

[0043] In the disclosed embodiment, the air conditioning system should focus on comfort, which is closely related to the flow of people, internal heat sources, etc., and comfort is a range rather than a fixed point. Comfort can be determined by temperature and humidity. Therefore, the adjustable parameters in the strategy space of the air conditioning system can include temperature and humidity. Under certain state parameters, the human body's comfortable temperature and comfortable humidity have a range. Here, the lower limit of the comfortable temperature is represented as Tc min , the upper limit of the comfortable temperature is expressed as Tc max , the lower limit of comfortable humidity is expressed as Hc min , the upper limit of comfortable humidity is expressed as Hc max , the optimal temperature is expressed as Tc opt , the optimal humidity is expressed as Hc opt .

[0044] In the embodiment of the present disclosure, an air conditioning system includes multiple air conditioning units, each of which synchronously adopts the same value of an adjustable parameter. For example, the adjustable parameters in the policy space of the air conditioning system include the temperature and humidity of the supply air. Each adjustable parameter has m2 optional values. The policy space of the air conditioning system is defined as Sr2. The expression of the policy space Sr2 of the air conditioning system is as follows:

[0045] In the above expression, u2 represents the air supply temperature of the air conditioning system, v2 represents the humidity of the air conditioning system, δ2 represents the humidity adjustment step of the air conditioning system, and δ3 represents the humidity adjustment step of the air conditioning system. Furthermore, the current policy space of the air conditioning system can be denoted as Sr2(u2,v2).

[0046] In the disclosed embodiments, the ventilation system includes multiple return and exhaust fans. The system's goal is to control indoor carbon dioxide concentration, oxygen concentration, and harmful substances, with carbon dioxide concentration being the primary control target. The system achieves a stable and comfortable indoor environment by adjusting the fresh air ratio and starting and stopping the return and exhaust fans.

[0047] Take the ventilation system as an example, which includes p return and exhaust fans. For the kth return and exhaust fan among the p return and exhaust fans, the carbon dioxide concentration monitored is GC k,in , the fresh air ratio is set to RA k , air volume is QW k , the volume of the controlled space under normal atmospheric pressure is V kFor all exhaust fans, the carbon dioxide concentration must not exceed the concentration threshold GC k,lim , the carbon dioxide concentration of fresh air is GC k,out , the fresh air enthalpy is Ha k,out In the above case, after the ventilation system is activated and the air circulation stabilizes, the expected carbon dioxide concentration in the interior space GC k It can be expressed by the following formula: GC k =RA k GC k,out +(1-RA k )GC k,in .

[0048] In order to achieve the above desired carbon dioxide concentration GC k , the opening time τ of the kth exhaust fan k It can be calculated using the following formula:

[0049] The power of the exhaust fan is related to the air volume and is almost unaffected by other factors. The power of the kth exhaust fan is P k It can be calculated using the following formula: k =f k (QW k ).

[0050] In the disclosed embodiment, each exhaust fan in the ventilation system synchronously uses the same adjustable parameter value. For example, the adjustable parameters in the ventilation system's strategy space include air volume and fresh air ratio. Each adjustable parameter has m3 selectable values. The ventilation system's strategy space is defined as Sr3. The expression of the ventilation system's strategy space Sr3 is as follows:

[0051] In the above expression, u3 represents the air volume of the exhaust fan in the ventilation system, δ4 represents the adjustment step of the air volume of the exhaust fan, QW max Indicates the upper limit of the air volume of the exhaust fan, QW min The lower limit of the air volume of the return and exhaust fans; v3 represents the fresh air ratio of the return and exhaust fans in the ventilation system, δ5 represents the adjustment step of the fresh air ratio of the return and exhaust fans, RA max Indicates the upper limit of the fresh air ratio of the return and exhaust fans, RA min The lower limit of the fresh air ratio of the return exhaust fan. Furthermore, the current strategy space of the ventilation system can be recorded as Sr3(u3,v3).

[0052] In conjunction with the linkage control device for a feng shui combined system provided in an embodiment of the present disclosure, an embodiment of the present disclosure provides a linkage control method for a feng shui combined system. As shown in FIG2 , the linkage control method for a feng shui combined system includes:

[0053] S201: The control device obtains the current policy space of each system.

[0054] In step S202 , the control device substitutes the current policy space of each system into a pre-built benefit evaluation function, and iteratively substitutes the adjacent policy space of the current policy space of each system into the benefit evaluation function until the function value of the benefit evaluation function reaches a maximum.

[0055] S203, the control device uses the adjacent strategy space of each system in the benefit evaluation function when the function value reaches the maximum as the new strategy space of each system.

[0056] As mentioned above, the policy space of each system contains at least one tunable parameter of the system.

[0057] Optionally, the adjustable parameters in the water system's policy space include at least one control parameter of each device and the start / stop status of each device. Here, the current control parameter and the current start / stop status of each device in each water system can be obtained to obtain the current policy space of the water system.

[0058] Optionally, the adjustable parameters in the air conditioning unit system policy space include the temperature and humidity of the air supply. Here, the current temperature and humidity of the air supply of the air conditioning unit system can be obtained to obtain the current policy space of the air conditioning unit system.

[0059] Optionally, the adjustable parameters in the ventilation system's strategy space include air volume and fresh air ratio. Here, the current air volume and fresh air ratio of the ventilation system can be obtained to obtain the current strategy space of the ventilation system.

[0060] Here, the benefit evaluation function is composed of the marginal benefit functions of each system. Each marginal benefit function represents the difference between the benefit value of the current strategy space of the system and the benefit value of the adjacent strategy space. The benefit value of each system is calculated using the benefit function of the system.

[0061] In the disclosed embodiments, for each system's current policy space, by adjusting at least one adjustable parameter in the current policy space, the benefit value of the system's current policy space and its adjacent policy space can be obtained. For each adjacent policy space obtained, the adjacent policy space can be substituted into the benefit evaluation function to calculate the function value of the benefit evaluation function.

[0062] It is understandable that each time the function value of the benefit evaluation function is obtained, it can be determined whether the function value of the benefit evaluation function has reached a maximum. When it is determined that the function value of the benefit evaluation function has reached a maximum, the substitution of the benefit evaluation function into the adjacent strategy space is stopped.

[0063] The coordinated control method for a feng shui integrated system provided by the disclosed embodiments pre-establishes a benefit evaluation function consisting of a marginal effect function that characterizes the degree of difference between the benefit value of each system's current policy space and the benefit value of an adjacent policy space. After substituting each system's current policy space into the pre-established benefit evaluation function, the benefit evaluation function is iteratively substituted into the adjacent policy space of each system's current policy space. Based on the function value of the benefit evaluation function, a reasonable adjacent policy space is selected from the adjacent policy space for each system, thereby achieving dynamic optimization of the policy space. Each determined reasonable adjacent policy space is used as the new policy space of the corresponding system. The control action indicated by each system's new policy space at the next time step is the optimal solution for all systems based on the current state. In this way, there is no need to pre-set, debug, and rigid control logic for the feng shui integrated system. By controlling each system to operate according to the adjustable parameters in the new policy space, the coordinated control of each system in the feng shui integrated system can be flexibly and accurately achieved based on the actual situation of each system, which helps to improve the overall energy saving and comfort of the feng shui integrated system.

[0064] In some embodiments, the benefit evaluation function represents the sum of the function values ​​of the marginal effect functions of all systems. The current policy space of each system is substituted into a pre-constructed benefit evaluation function, and the adjacent policy space of the current policy space of each system is iteratively substituted into the benefit evaluation function until the function value of the benefit evaluation function reaches a maximum, including: substituting the current policy space of each system into the corresponding marginal effect function, and substituting the adjacent policy space of the current policy space of the corresponding system into each marginal effect function; each time the adjacent policy space of the current policy space of the corresponding system is substituted into a marginal effect function, the function value of the marginal effect function of all systems is calculated; the sum of the function values ​​of the marginal effect functions of all systems is used as the function value of the benefit evaluation function, and when it is determined that the function value of the benefit evaluation function has reached a maximum, the substitution of the adjacent policy space into the marginal effect function is stopped.

[0065] This disclosed embodiment constructs a reasonable marginal benefit function for each system based on its actual control objectives and the interactions between systems. By comprehensively judging whether the adjacent policy space can meet the benefits required by each system using the function values ​​of the marginal benefit functions of all systems, it helps to more rationally screen new policy spaces for each system and accurately optimize the policy space.

[0066] 3 , an embodiment of the present disclosure provides another linkage control method for a Feng Shui combined system. The linkage control method for a Feng Shui combined system includes:

[0067] S301: The control device obtains the current policy space of each system.

[0068] S302: The control device substitutes the current policy space of each system into the corresponding marginal effect function, and substitutes the adjacent policy space of the current policy space of the corresponding system into each marginal effect function.

[0069] S303 , the control device calculates the function values ​​of the marginal effect functions of all systems after substituting the adjacent policy space of the current policy space of the corresponding system into a marginal effect function each time.

[0070] S304, the control device uses the sum of the function values ​​of the marginal effect functions of all systems as the function value of the benefit evaluation function, and stops substituting the adjacent strategy space into the marginal effect function when it is determined that the function value of the benefit evaluation function reaches the maximum.

[0071] S305 , the control device uses the adjacent strategy space of each system in the benefit evaluation function when the function value reaches the maximum as the new strategy space of each system.

[0072] In the disclosed embodiments, for each system's current policy space, by adjusting at least one adjustable parameter in the current policy space, the benefit value of the system's current policy space and its adjacent policy space can be obtained. Each adjacent policy space obtained can be substituted into the benefit evaluation function, and the function value of the benefit evaluation function can be calculated using hysteresis.

[0073] In some embodiments, a system's marginal benefit function represents the difference between the system's current comprehensive benefit value in its strategy space and the comprehensive benefit value in adjacent strategy spaces. Each system's comprehensive benefit value is calculated using its comprehensive benefit function, which is based on its independent benefit function and the independent benefit functions of other systems that have an impact on it.

[0074] The embodiments of the present disclosure fully consider the mutual influence between systems, and determine the reasonable comprehensive benefit value of each system based on the influence relationship between the systems, so as to accurately calculate the comprehensive benefit value corresponding to each adjacent space strategy based on the comprehensive benefit value, and then calculate the accurate function value of the marginal effect function, which helps to reasonably screen out the new strategy space of each system.

[0075] In some embodiments, the comprehensive benefit function of each system is constructed based on the product of the independent benefit function of the system and the first weight coefficient, and the product of the independent benefit functions of other systems that have an impact on the system and the second weight coefficient.

[0076] The embodiment of the present disclosure determines the specific type of influence relationship between systems to determine the weight coefficients of each independent benefit function constituting the system, and then obtains a reasonable comprehensive benefit value for each system to ensure that a new strategy space for each system is reasonably screened out.

[0077] The first weight coefficient and the second weight coefficient are pre-set. The positive or negative value of the second weight coefficient is related to the type of influence relationship, which includes cooperative and competitive relationships. Specifically, the water system and the air conditioning system have a cooperative relationship. The second weight coefficient corresponding to the independent benefit function of the air conditioning system in the comprehensive benefit function of the water system is positive, and the second weight coefficient corresponding to the independent benefit function of the water system in the comprehensive benefit function of the air conditioning system is positive. The water system and the ventilation system have a competitive relationship. The second weight coefficient corresponding to the independent benefit function of the ventilation system in the comprehensive benefit function of the water system is negative, and the second weight coefficient corresponding to the independent benefit function of the water system in the comprehensive benefit function of the ventilation system is negative.

[0078] In some embodiments, the independent benefit function for the water system is related to the system's power and the start / stop status of each device in the system. The power of the water system is affected by the strategy space used by the ventilation system. Based on the characteristics and control objectives of the water system's devices, the independent benefit function is constructed using the system's power and the start / stop status of each device. This allows the independent benefit function to accurately describe the water system's revenue, facilitating the construction of an accurate and reasonable comprehensive benefit function based on the water system's independent benefit function.

[0079] In some embodiments, the independent benefit function of the air conditioning system is related to the power of the air conditioning system and the deviation of the temperature and humidity of the air supplied by the air conditioning system from the corresponding optimal temperature and humidity, wherein the power of the air conditioning system is affected by the strategy space used by the water system. Based on the control objective of the air conditioning system, the independent benefit function is constructed based on the power of the air conditioning system and the deviation of the temperature and humidity of the air supplied by the air conditioning system from the corresponding optimal temperature and humidity. This independent benefit function accurately describes the benefits of the air conditioning system, facilitating the construction of an accurate and reasonable comprehensive benefit function based on the independent benefit function of the air conditioning system.

[0080] In some embodiments, the independent benefit function of the ventilation system is related to the power of the ventilation system and the carbon dioxide concentration in the space corresponding to the ventilation system. Based on the control objective of the ventilation system, the independent benefit function is constructed based on the power of the ventilation system and the carbon dioxide concentration in the space corresponding to the ventilation system. This allows the independent benefit function to accurately describe the benefits of the ventilation system, facilitating the construction of an accurate and reasonable comprehensive benefit function based on the independent benefit function of the ventilation system.

[0081] In the embodiment of the present disclosure, the policy space of the water system can be linked to derive the benefit function of the water system. Specifically, it is first necessary to establish a mapping W1 to calculate the total power of the water system. Among them, the mapping W1 is the mapping of the total power of the water system. Taking into account practical applications and reducing the occupation of computing resources, width learning rather than deep learning methods is used. The set of control parameters and the set of start and stop states of each device in the policy space of the water system are modeled using multi-layer perceptrons, and finally the width outputs an array of length n (that is, the number of devices in the water system), and the sum of the elements of the array is the total power of the water system. It can be understood that W1 is a mapping of the total power of the water system without considering the influence of other systems on the water system.

[0082] The start and stop states of each device in the water system's policy space will be affected by the ventilation system's policy space Sr3. The mapping of the ventilation system's policy space Sr3's impact on the start and stop states of each device in the water system's policy space is g3,1.

[0083] The total power of the water system is expressed as The total power of the water system can be expressed by the following formula:

[0084] At the same time, considering the stability of the system, it is necessary to impose certain restrictions on the switching operation of the start and stop states of the equipment. For each device, there should be a necessary interval time for the start and stop switching. If the switch is started before the start and stop state switching interval is reached, a penalty coefficient is assigned to make the optimization go in the right direction. Now assume that the necessary interval time for the start and stop switching of the jth device in the water system is τ j , then the jth device τ j The start and stop state before time is v t -τ j , because the start-stop state is only 0 or 1, a penalty coefficient of θ is given j , becomes a restriction. Assuming the t subscript represents the current moment, the independent benefit function of the water system itself is expressed as G1([Sr1, Sr2, Sr3]). The expression of the independent benefit function of the water system G1([Sr1, Sr2, Sr3]) is as follows:

[0085] Among them, P 1t Indicates the current total power of the water system.

[0086] According to the above expression, the independent benefit function of the water system is related to the power of the water system and the start and stop status of each device in the water system. Among them, the power of the water system is affected by the strategy space used by the ventilation system.

[0087] In the disclosed embodiment, the benefit function of the air conditioning system can be derived by linking the policy space of the air conditioning system. The air conditioning system control mainly controls the temperature and humidity of the air supply to ensure that the air supply to the user meets the comfort requirements. The air conditioning system can generally receive transmission parameters from the water system, including the water outlet temperature T ch and the flow rate Q of the refrigeration pump ld , both of which jointly affect the temperature and humidity of the air supplied by the air-conditioning system, as well as the cooling efficiency of the air-conditioning system.

[0088] In order to construct the independent benefit function of the air conditioning system, we first need to determine the expression of the total power of the air conditioning system. Assuming that the air conditioning system includes r air conditioning units, we now establish a mapping W2, which is the mapping of the total power of the air conditioning system. 2,k is the mapping of the power of the kth air-conditioning unit in the air-conditioning unit system, and the environmental parameters (indoor and outdoor temperature and humidity, etc.) corresponding to the kth air-conditioning unit are expressed as S 2,k The transfer parameters of the water system corresponding to the kth air-conditioning unit (water outlet temperature and chilled pump flow) are expressed as S 1,k , the transfer parameter S of the water system corresponding to the kth air-conditioning unit 1,k The mapping is represented as g 1,2 The total power of the air conditioning system is expressed as Total power of air conditioning system It can be expressed by the following formula:

[0089] Furthermore, since the control target of the air conditioning system is comfort, the closer the temperature and humidity of the air supplied by the air conditioning system are to the optimal temperature and optimal humidity, the more suitable it is for the optimized control logic of the air conditioning system. In the embodiment disclosed herein, it is necessary to assign a weight value to the energy consumption and optimal deviation of the air conditioning system, respectively. This value needs to be determined by the business personnel themselves, that is, the business personnel believe that the air conditioning should be more inclined towards energy saving or comfort. Among them, the energy consumption of the air conditioning system is related to the power of the air conditioning system; the optimal deviation indicates the degree of deviation of the temperature and humidity of the air supplied by the air conditioning system from the optimal temperature and optimal humidity.

[0090] The independent benefit function of the air-conditioning unit system itself is expressed as G2([Sr1, Sr2, Sr3]). The expression of the independent benefit function G2([Sr1, Sr2, Sr3]) of the air-conditioning unit system is as follows:

[0091] Among them, (|u2-Tc opt |+|v2-Hc opt|) represents the optimal deviation, ω1 and ω2 are the weight values ​​corresponding to energy consumption and optimal deviation, respectively.

[0092] According to the above expression, the independent benefit function of the air conditioning system is related to the power of the air conditioning system and the deviation of the temperature and humidity of the air supplied by the air conditioning system from the corresponding optimal temperature and humidity. Among them, the power of the air conditioning system is affected by the strategy space used by the water system.

[0093] In the disclosed embodiments, the ventilation system's strategy space can be combined to derive an independent benefit function for the ventilation system. The ventilation system's goal is to control indoor carbon dioxide concentration, oxygen concentration, and harmful substances, with carbon dioxide concentration being the primary control target. The ventilation system achieves a stable and comfortable indoor environment by adjusting the fresh air ratio and starting and stopping the return and exhaust fans.

[0094] Assume that the ventilation system includes p return and exhaust fans. For the kth return and exhaust fan among the p return and exhaust fans, the carbon dioxide concentration monitored is GC k,in , the fresh air ratio is set to RA k , air volume is QW k , the volume of the controlled space under normal atmospheric pressure is V k For all exhaust fans, the carbon dioxide concentration must not exceed the concentration threshold GC k,lim , the carbon dioxide concentration of fresh air is GC k,out , the fresh air enthalpy is Ha k,out In the above case, after the ventilation system is activated and the air circulation stabilizes, the expected carbon dioxide concentration in the interior space GC k It can be expressed by the following formula: GC k =RA k GC k,out +(1-RA k )GC k,in .

[0095] In order to achieve the above desired carbon dioxide concentration GC k , the opening time τ of the kth exhaust fan k It can be calculated using the following formula:

[0096] The power of the exhaust fan is related to the air volume and is almost unaffected by other factors. The power of the kth exhaust fan is P k It can be calculated using the following formula: k =f k (QW k ).

[0097] In order to construct an independent benefit function for the ventilation system, we first need to determine the expression for the total power of the ventilation system. Now we establish a mapping W3, which is the mapping of the total power of the ventilation system. The total power of the ventilation system is expressed as Total power of ventilation system It can be expressed by the following formula:

[0098] Ventilation systems must balance comfort and energy consumption. Comfort is defined as achieving a consistent CO2 concentration in the space. It's important to note that reducing CO2 concentration below a threshold can earn rewards, but lowering it too low is ineffective. Therefore, business personnel must independently determine the weighting of energy consumption and CO2 concentration. The energy consumption of an air conditioning system is related to its power.

[0099] The independent benefit function of the ventilation system itself is expressed as G3([Sr1, Sr2, Sr3]). The expression of the independent benefit function G3([Sr1, Sr2, Sr3]) of the ventilation system is as follows: in, and are the weight values ​​corresponding to the achievement of energy consumption and carbon dioxide concentration respectively.

[0100] According to the above expression, the independent benefit function of the ventilation system is related to the power of the ventilation system and the carbon dioxide concentration in the space corresponding to the ventilation system.

[0101] In the embodiment of the present disclosure, the ventilation system needs to transmit the maximum opening time max (τ k ), maximum opening time max(τ k ), used to calculate the unified caliber benefit function as the collaborative benefit function. Here, the maximum opening time max(τ k ) is expressed as τ3, and the maximum opening time τ3 can be calculated using the following formula:

[0102] In the embodiment of the present disclosure, as described above, the comprehensive benefit function of each system is obtained based on the independent benefit function of the system and the independent benefit functions of other systems that have an influencing relationship with the system. Some control parameters in the water system (such as the outlet water temperature and the flow rate of the refrigeration pump) will be transmitted to the air-conditioning unit system, so that the air-conditioning unit system can achieve comfort with lower energy consumption, so there is a cooperative relationship between the water system and the air-conditioning unit system. At the same time, the introduction of more fresh air into the ventilation system will be beneficial to its control of carbon dioxide concentration, but it will increase the energy consumption of the water system (for example, leading to an increase in cooling demand). Therefore, there is a competitive relationship between the water system and the ventilation system.

[0103] In the disclosed embodiment, the comprehensive benefit function of each system is constructed based on the product of the system's independent benefit function and the first weight coefficient, and the product of the independent benefit functions of other systems that have an impact on the system and the second weight coefficient. It is understood that the water system and the air conditioning system have an impact relationship, specifically a cooperative relationship; the water system and the ventilation system have an impact relationship, specifically a competitive relationship.

[0104] The comprehensive benefit function of the water system is expressed as U1([Sr1, Sr2, Sr3]). The expression of the comprehensive benefit function U1([Sr1, Sr2, Sr3]) is as follows:

[0105] U1([Sr1, Sr2, Sr3])=C 11 G1([Sr1, Sr2, Sr3])·τ3+C 13 G3([Sr1,Sr2,Sr3]), in the above expression, C 11 is the first weight coefficient, C 13 is the second weight coefficient, C 13 is a negative number.

[0106] The comprehensive benefit function of the air-conditioning unit system is expressed as U2([Sr1, Sr2, Sr3]). The expression of the comprehensive benefit function U2([Sr1, Sr2, Sr3]) is as follows:

[0107] U2([Sr1, Sr2, Sr3])=C 22 G2([Sr1, Sr2, Sr3])·τ3+C 21 G1([Sr1, Sr2, Sr3])·τ3, in the above expression, C 22 is the first weight coefficient, C 21 is the second weight coefficient, C 21 Is a positive number.

[0108] The comprehensive benefit function of the ventilation system is expressed as U3([Sr1, Sr2, Sr3]). The expression of the comprehensive benefit function U3([Sr1, Sr2, Sr3]) is as follows:

[0109] U3([Sr1, Sr2, Sr3])=C 33 G3([Sr1,Sr2,Sr3])+G 31 ([Sr1, Sr2, Sr3])·τ3, in the above expression, C 33 is the first weight coefficient, G 31 is the second weight coefficient, G 31 is a negative number.

[0110] In the disclosed embodiment, the marginal benefit function of each system represents the degree of difference between the benefit value of the system's current policy space and the benefit value of the adjacent policy space. Specifically, the marginal benefit function of each system represents the difference between the benefit value of the system's current policy space and the benefit value of the adjacent policy space. The benefit value of each system is calculated using the benefit function of the system. In other words, the marginal benefit function of each system is represented by the benefit function of the system.

[0111] Furthermore, the marginal benefit function of each system represents the degree of difference between the comprehensive benefit value of the system's current strategy space and the comprehensive benefit value of the adjacent strategy space. Specifically, the marginal benefit function of each system represents the difference between the comprehensive benefit value of the system's current strategy space and the comprehensive benefit value of the adjacent strategy space. The marginal benefit function of each system is calculated from the comprehensive benefit function of the system, that is, the marginal benefit function of each system is represented by the comprehensive benefit function of the system.

[0112] The marginal effect function of the water system is expressed as MU1([Sr1, Sr2, Sr3]). The expression of the marginal effect function MU1([Sr1, Sr2, Sr3]) is as follows:

[0113] MU1([Sr1, Sr2, Sr3]) = U1([Sr1, Sr2, Sr3]) - U1([Sr1′, Sr2, Sr3]). In the above expression, Sr1′ is the adjacent strategy space of the water system's current strategy space. Substituting the water system's current strategy space into U1([Sr1, Sr2, Sr3]) in the expression, and substituting a neighboring strategy space of the water system's current strategy space into U1([Sr1′, Sr2, Sr3]) in the expression, we can obtain the difference between the comprehensive benefit value of the water system's current strategy space and the comprehensive benefit value of the neighboring strategy space, that is, the function value of the water system's marginal benefit function.

[0114] The marginal effect function of the air-conditioning unit system is expressed as MU2([Sr1, Sr2, Sr3]). The expression of the marginal effect function MU2([Sr1, Sr2, Sr3]) is as follows:

[0115] MU2([Sr1, Sr2, Sr3]) = U2([Sr1, Sr2, Sr3]) - U2([Sr1, Sr2′, Sr3]). In the above expression, Sr2′ is the adjacent policy space of the air conditioning system's current policy space. Substituting the air conditioning system's current policy space into U2([Sr1, Sr2, Sr3]) in the expression, and substituting a neighboring policy space of the air conditioning system's current policy space into U2([Sr1, Sr2′, Sr3]) in the expression, we can obtain the difference between the comprehensive benefit value of the air conditioning system's current policy space and the comprehensive benefit value of the neighboring policy space, that is, the function value of the air conditioning system's marginal benefit function.

[0116] The marginal effect function of the ventilation system is expressed as MU3([Sr1, Sr2, Sr3]). The expression of the marginal effect function MU3([Sr1, Sr2, Sr3]) is as follows:

[0117] MU3([Sr1, Sr2, Sr3]) = U3([Sr1, Sr2, Sr3]) - U3([Sr1, Sr2, Sr3′]). In the above expression, Sr3′ is the adjacent strategy space of the ventilation system's current strategy space. Substituting the ventilation system's current strategy space into U3([Sr1, Sr2, Sr3]) in the expression, and substituting a neighboring strategy space of the ventilation system's current strategy space into U3([Sr1, Sr2, Sr3′]) in the expression, we can obtain the difference between the comprehensive benefit value of the ventilation system's current strategy space and the comprehensive benefit value of the neighboring strategy space, that is, the function value of the ventilation system's marginal benefit function.

[0118] Searching the optimal strategy space for the water system, air conditioning unit system, and ventilation system aims to maximize the marginal effect, that is, to maximize the sum of the marginal effect functions of the water system, the air conditioning unit system, and the ventilation system. Therefore, the benefit evaluation function can represent the sum of the marginal effect functions of all systems (i.e., the water system, the air conditioning unit system, and the ventilation system). Here, greedy search algorithms (such as particle swarm optimization, genetic algorithms, and annealing algorithms) are used to maximize this sum.

[0119] In an embodiment of the present disclosure, the expression of the benefit evaluation function for solving the maximum value of the sum of the function values ​​of the marginal effect functions of the water system, the air-conditioning unit system and the ventilation system is as follows: max(MU1([Sr1, Sr2, Sr3]), MU2([Sr1, Sr2, Sr3]), MU3([Sr1, Sr2, Sr3])).

[0120] Assuming that the function value of the benefit evaluation function reaches the maximum, the adjacent strategy spaces of the water system, air conditioning system and ventilation system in the benefit evaluation function are Sr2(u2 * ,v2 * ) and Sr3(u3 * ,v3 * ), then these three adjacent strategy spaces are the optimal strategy space combination that conforms to the current situation. These three adjacent strategy spaces can be used as new strategy spaces for the water system, air-conditioning unit system, and ventilation system respectively.

After substituting each system's current policy space into the pre-established benefit evaluation function, the device iteratively substitutes the adjacent policy space of each system's current policy space into the benefit evaluation function, and based on the function value of the benefit evaluation function, selects a reasonable adjacent policy space for each system from the adjacent policy space, thereby achieving dynamic optimization of the policy space. Each determined reasonable adjacent policy space is used as the new policy space of the corresponding system. The control action indicated by each system's new policy space at the next time step is the optimal solution for all systems based on the current state. In this way, there is no need to pre-set and debug the rigid and fixed control logic of the feng shui integrated system. By controlling each system to operate according to the various adjustable parameters in the new policy space, the various systems in the feng shui integrated system can be flexibly and accurately linked to each other according to their actual conditions, thereby contributing to the overall energy saving and comfort improvement of the feng shui integrated system.

[0134] Each time a marginal effect function is substituted into the adjacent strategy space of the current strategy space of the corresponding system, the function value of the marginal effect function of all systems is calculated;

[0135] The sum of the function values ​​of the marginal effect functions of all systems is used as the function value of the benefit evaluation function. When it is determined that the function value of the benefit evaluation function reaches the maximum, the marginal effect function is stopped from being substituted into the adjacent strategy space.

[0136] In some embodiments, the new policy determination module 503 is further configured to control each system to operate according to various adjustable parameters in the new policy space.
