Description
Technical Field
[0001] This invention belongs to the field of building energy system operation and control technology, specifically relating to a method, system and equipment for predicting water world condensation heat. Background Technology
[0002] Water parks, hot spring resorts, and similar venues typically require simultaneous cooling, hot water supply, and pool temperature control. The condensation heat generated during the operation of the refrigeration units can be recovered through a heat recovery loop and supplied to hot water preparation, heat storage, or pool water heat exchange processes.
[0003] In the prior art, Chinese patent document CN101191680A discloses a two-stage total heat recovery water-cooled screw chiller unit. This unit utilizes a primary heat recovery unit, a secondary heat recovery unit, an electric regulating valve, and a PLC temperature control system to recover condensation heat in stages, and obtains hot water at different temperatures by adjusting the water flow and bypass ratio. This solution focuses on the unit's heat exchange structure and the formation of different outlet water temperatures.
[0004] For aquatic heating and cooling systems, condensate heat recovery typically faces different heat sinks. Hot water storage tanks tend to receive higher-temperature hot water, while pool water tends to be absorbed at a lower temperature and slower rate of constant temperature. These two types of water differ in temperature quality, receiving speed, and risk of overflow. If condensate heat is still allocated according to a fixed priority, fixed water temperature threshold, or single-cycle adjustment method, it is easy for condensate heat to enter a heat sink that is incompatible with the current receiving capacity.
[0005] Therefore, in the water world condensation heat recovery scenario, there is still a need for a technical solution that can confirm the adjustable condensation heat within the allocation cycle and perform rolling predictive allocation in combination with different heat sink receiving constraints. Summary of the Invention
[0006] The purpose of this invention is to provide a method, system, and device for predicting condensation heat in a water world, which solves the problem that it is difficult to match and allocate condensation heat to different heat sinks such as hot water storage tanks and swimming pool water in a water world cold and heat source system according to heat sink receiving constraints.
[0007] To solve the above-mentioned technical problems, the present invention is implemented using the following technical solution.
[0008] On the one hand, a method for predicting the rolling condensation heat of the water world includes: The heat response of the condensing heat recovery loop is obtained according to the allocation cycle, and the consistency is verified with the refrigeration side operation response synchronized with the heat response to determine the adjustable condensing heat that can be allocated in the current cycle. The upper limit for high-grade reception is determined based on the heat storage margin of the hot water storage tank relative to the target water supply state, and the upper limit for low-grade absorption is determined based on the remaining temperature rise margin of the pool water relative to the target constant temperature range. The upper limit for high-grade reception and the upper limit for low-grade absorption are then converted into heat sink constraints that are deducted periodically within the prediction window. Under the constraints of the heat sink and the temperature-raising capacity of the secondary temperature gradient heat pump, with the goal of reducing the amount of undissipated condensed heat and the amount of heat sink exceeding the limit, the restricted distribution sequence of the adjustable condensed heat is obtained among the high-grade receiving path, the low-grade dissipation path and the restricted distribution path. Only the first item in the restricted allocation sequence corresponding to the current allocation cycle is taken as the allocation result, and path labels and cold and hot source operating parameters are generated accordingly. The initial allocation residual is generated based on the heat sink temperature response after execution, and the high-grade reception limit, low-grade absorption limit, or path switching cost of the next prediction window is corrected using the initial allocation residual.
[0009] Preferably, determining the adjustable condensing heat that can be allocated in the current cycle includes: removing the start-stop switching segment and invalid fluctuation segment from the heat response of the condensing heat recovery loop to obtain the effective heat response of the current cycle; comparing the effective heat response with the refrigeration side operation response in a synchronous trend; and converting the effective heat response into adjustable condensing heat when the two maintain a corresponding relationship in the current cycle.
[0010] Preferably, the high-grade receiving limit is formed based on the difference between the current heat storage state of the hot water storage tank and the target water supply state, and the low-grade absorption limit is formed based on the remaining temperature rise margin between the current constant temperature state of the pool water and the target constant temperature range; and the high-grade receiving limit and the low-grade absorption limit are respectively converted into receiving constraints under the same metering scale as the adjustable condensing heat.
[0011] Preferably, converting the high-grade receiving limit and the low-grade consumption limit into heat sink constraints that are deducted periodically within the prediction window includes: updating the high-grade receiving limit and the low-grade consumption limit by decreasing them according to the arranged receiving volume of each allocation period within the prediction window; when the decreasing update result of any allocation period is lower than the minimum receiving requirement of the corresponding path, blocking the new allocation of the corresponding path within that allocation period.
[0012] Preferably, before determining the restricted allocation sequence, a feasible path domain is established based on the temperature grade of the adjustable condensing heat, the upper limit of high-grade reception, the upper limit of low-grade absorption, and the temperature-raising capacity of the secondary temperature gradient heat pump; wherein, the high-grade reception path is constrained by both the upper limit of high-grade reception and the temperature-raising capacity, the low-grade absorption path is constrained by the upper limit of low-grade absorption, and the restricted allocation path is used to accept the remaining condensing heat that does not meet the aforementioned feasible path conditions.
[0013] Preferably, the restricted allocation sequence includes the path selection results and path allocation amounts corresponding to each allocation cycle within the prediction window; when obtaining the restricted allocation sequence, the amount of unconsumed condensed heat, the amount of heat sink exceeding the limit, and the cost of path switching are used together as the sequence evaluation basis, and the path allocation combination that makes the sequence evaluation results meet the preset convergence conditions is selected as the restricted allocation sequence.
[0014] Preferably, using only the first item in the restricted allocation sequence corresponding to the current allocation cycle as the allocation result includes: when the first item points to a high-grade receiving path and requires temperature increase, generating a temperature increase tank entry tag and forming linkage operation parameters between the secondary temperature gradient heat pump and the heat storage heat exchange side; when the first item points to a high-grade receiving path and does not require temperature increase, generating a heat storage receiving tag and forming receiving operation parameters for the heat storage heat exchange side; when the first item points to a low-grade consumption path, generating a pool consumption tag and forming limiting operation parameters for the pool heat exchange side; when the first item points to a restricted allocation path, generating a recovery restricted tag and restricting new allocations of condensed heat entering the heat sink side in the current cycle.
[0015] Preferably, the first allocation residual includes a high-grade receiving residual and a low-grade absorption residual; when the high-grade receiving residual indicates that the actual reception of the hot water storage tank is insufficient, the upper limit of high-grade receiving in the next prediction window is reduced or the path switching cost of the high-grade receiving path is increased; when the low-grade absorption residual indicates that the temperature rise of the pool water exceeds the allowable change, the upper limit of low-grade absorption in the next prediction window is reduced; when the execution feedback indicates that the path action is not completed, the corresponding residual is marked as an execution residual, and the execution residual is prevented from directly correcting the upper limit of heat sink reception.
[0016] On the other hand, the present invention provides a water world condensation heat rolling prediction system, comprising: The system includes a heat response acquisition terminal, a heat sink response acquisition terminal, an execution feedback acquisition terminal, a rolling prediction controller, and a high-grade receiving execution side, a low-grade absorption execution side, and a limited allocation execution side, each controlled by the rolling prediction controller. The heat response acquisition terminal is communicatively connected to the condensation heat recovery loop and the refrigeration side operation loop, and is used to provide the rolling predictive controller with mutually synchronized heat response and refrigeration side operation response; The heat sink response acquisition terminal is communicatively connected to the hot water storage tank and the pool water body, and is used to provide the rolling prediction controller with a heat sink response that can characterize the upper limit of high-grade reception and the upper limit of low-grade consumption. The rolling prediction controller is used to determine the adjustable condensing heat according to the allocation cycle, convert the high-grade receiving upper limit and the low-grade consumption upper limit into heat sink constraints that are deducted periodically within the prediction window, and obtain the restricted allocation sequence of condensing heat among the high-grade receiving execution side, the low-grade consumption execution side and the restricted allocation execution side under the heat sink constraints. The rolling prediction controller only sends the first item in the restricted allocation sequence corresponding to the current allocation period to the corresponding execution side; The execution feedback acquisition terminal is used to obtain the heat sink temperature response after execution, and return the first allocation residual formed by the heat sink temperature response to the rolling prediction controller, so that the rolling prediction controller can correct the high-grade reception limit, low-grade absorption limit or path switching cost of the next prediction window.
[0017] On the other hand, the present invention provides a water world condensation heat rolling prediction device, including a processor, a memory and a data interface connected to the processor. The memory stores a computer program. When the processor executes the computer program, it obtains the heat response of the condensation heat recovery loop, the refrigeration side operation response and the heat sink temperature response through the data interface, and executes the water world condensation heat rolling prediction method.
[0018] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: 1. After verifying the consistency between the heat response of the condensing heat recovery loop and the operating response of the refrigeration side, the adjustable condensing heat that can participate in the allocation for the current cycle is determined. Therefore, the condensing heat entering the subsequent allocation process has a corresponding basis between the condensing heat recovery side and the refrigeration operation side, which can reduce the impact of start-stop switching sections, branch disturbance sections, or invalid fluctuation sections on the condensing heat allocation judgment, ensuring that the subsequent allocation targets are limited to the adjustable condensing heat confirmed by the operating status.
[0019] 2. By converting the heat storage margin of the hot water storage tank relative to the target water supply state into a high-grade receiving upper limit, and the remaining temperature rise margin of the pool water relative to the target constant temperature range into a low-grade absorption upper limit, and further converting these into heat sink constraints deducted periodically within the prediction window, the high-temperature receiving capacity of the hot water storage tank and the low-speed constant temperature absorption capacity of the pool water are no longer judged as parallel state quantities, but participate in the constraint under the same distribution scale, so that the condensation heat distribution process can be simultaneously limited by the high-grade receiving boundary and the low-grade absorption boundary.
[0020] 3. By obtaining a constrained allocation sequence under the constraints of heat sink and the temperature-raising capacity of the secondary gradient heat pump, only the first item corresponding to the current allocation cycle is used as the execution allocation result. The allocation residual of the first item after execution is used to correct the high-grade receiving upper limit, low-grade consumption upper limit, or path switching cost of the next prediction window. Therefore, the subsequent allocation results in the prediction window will not be fixed and executed at once, and the actual heat sink response of the current cycle can participate in the correction of the next window, enabling the condensation heat allocation process to have the ability to adjust rollingly according to the heat sink receiving status.

[0028] The technical solution of the present invention will be further described below with reference to the embodiments. It should be understood that the following embodiments are used to illustrate the implementation of the present invention and do not constitute a limitation on the scope of protection of the present invention. Unless otherwise expressly limited, the allocation cycle, prediction window length, weighting coefficient, correction coefficient, heat response formation method and communication interface form involved in the embodiments can all be set according to the engineering configuration and operating boundaries of the water world cold and heat source system.
[0029] This invention is applicable to energy systems in water parks, hot spring resorts, or similar integrated buildings that require refrigeration condensation heat recovery, hot water supply for bathing, and constant temperature for swimming pools. The condensation heat generated during the system's refrigeration operation is directed to a high-grade receiving path, a low-grade consumption path, or a restricted distribution path, depending on its temperature grade and the heat sink receiving status.
[0030] The high-grade receiving path is used to allow condensation heat to enter the hot water storage tank side. This high-grade receiving path includes, but is not limited to, a temperature-raising entry path where the water is heated by a two-stage temperature gradient heat pump before entering the hot water storage tank, and a heat storage receiving path where the water enters directly into the hot water storage tank without prior heating. The low-grade absorption path is used to allow condensation heat to enter the heat exchange side of the swimming pool water, and to absorb it at a low rate without disrupting the target constant temperature range of the pool. The restricted allocation path is used to limit the additional allocation to the heat sink side within the current allocation cycle, or to reduce the allocation ratio of condensation heat entering the heat sink side, when condensation heat is not suitable for entering the high-grade receiving path or the low-grade absorption path.
[0031] Example 1 refer to Figures 1 to 7 As shown in this embodiment, a rolling prediction method for condensation heat in a water world is provided. Instead of directly determining the destination of condensation heat based on fixed heat sink priorities, fixed seasonal patterns, or a single water temperature threshold, this method first determines the currently available adjustable condensation heat for allocation within each allocation cycle. Then, it processes the hot water storage tank and swimming pool water into high-grade receiving upper limits and low-grade dissipation upper limits, respectively. Within the prediction window, these upper limits are converted into heat sink constraints that are deducted periodically. The system obtains a restricted allocation sequence under the constraints of heat sink constraints and the temperature-raising capacity of the secondary temperature gradient heat pump. During execution, only the first term corresponding to the current allocation cycle in the restricted allocation sequence is used, and the heat sink temperature response after execution is used to form the residual of the first term allocation to correct the next prediction window.
[0032] Specific methods include: S101. Determine the adjustable condensing heat that can be allocated in the current cycle.
[0033] The heat response of the condensing heat recovery loop is obtained according to the allocation cycle. This heat response characterizes the detectable heat change on the condensing heat recovery side within the current allocation cycle, including but not limited to changes in the supply and return water temperatures on the condensing heat recovery side, the flow response on the heat exchange side, or the combined heat response of the heat recovery loop. To avoid misinterpreting start-stop switching, branch disturbances, or sampling anomalies as effective condensing heat generation, this embodiment simultaneously obtains the refrigeration side operating response. This refrigeration side operating response reflects whether the refrigeration operation side is in an effective operating state capable of generating condensing heat.
[0034] When the condensing heat recovery loop obtains the heat exchange side flow rate and supply / return water temperature, the original heat response of the condensing heat recovery loop in the kth regulation cycle is expressed as:
[0035] in, This represents the initial heat response of the condensation heat recovery loop during the kth adjustment cycle; This represents the equivalent volumetric heat capacity of the medium on the recovery side. This represents the effective flow rate on the recovery side during the k-th allocation cycle; and These represent the outlet water temperature and inlet water temperature on the recovery side, respectively. This indicates the duration of the allocation cycle. The above expression is used to illustrate the formation relationship of the heat response; in another embodiment, if the field control system has already output an equivalent heat response, then the equivalent heat response is directly read as... .
[0036] The effective heat response of the condensing heat recovery loop is extracted by removing start-stop switching segments and invalid fluctuation segments to obtain the effective heat response for the current period. The start-stop switching segment refers to a short-term unstable response segment caused by unit startup, shutdown, valve switching, or pump switching; the invalid fluctuation segment refers to a fluctuation segment where the heat response changes but cannot form a synchronous correspondence with the refrigeration side operating response. The effective heat response is expressed as:
[0037] in, This represents the effective heat response during the k-th allocation cycle; This indicates the extraction and processing of valid segments after removing start / stop switching segments and invalid fluctuation segments.
[0038] The effective heat response of the current cycle is compared with the cooling-side operating response to establish a synchronous trend. When the direction, duration, or range of change of the effective heat response corresponds in the same direction as the cooling-side operating response, the effective heat response is considered to represent the generation state of recoverable condensable heat in the current cycle, and its effectiveness is marked. When the two do not satisfy the same direction correspondence, let the validity mark be... .
[0039] Therefore, the adjustable condensation heat that can be allocated in the k-th allocation cycle is expressed as:
[0040] in, This represents the adjustable condensing heat within the k-th allocation cycle, indicating that only heat responses that have been extracted through effective segments and passed the consistency verification of the refrigeration-side operating response enter the subsequent restricted allocation sequence. In this case, the heat response of that cycle is not directly used as the adjustable condensing heat. Instead, an unconfirmable condensing heat marker is formed in the current allocation cycle to restrict the condensing heat of that cycle from entering the subsequent allocation sequence.
[0041] S102, establish upper limits for high-grade acceptance and low-grade consumption.
[0042] After determining the adjustable condensing heat capacity, the upper limit for high-grade receiving is determined based on the heat storage margin of the hot water storage tank relative to the target water supply state. The heat storage margin of the hot water storage tank is not simply the empty volume of the tank, but rather represents its ability to continue receiving high-grade condensing heat or condensing heat after temperature enhancement during the current and subsequent distribution cycles. This heat storage margin is formed by the difference between the current heat storage state of the hot water storage tank and the target water supply state, and is combined with the receiving status on the heat exchange side to determine whether it can enter the high-grade receiving path.
[0043] In one implementation, the upper limit for high-grade hot water receiving in the storage tank during the k-th allocation cycle is expressed as:
[0044] in, This represents the upper limit of high-grade reception for the hot water storage tank during the k-th allocation cycle; This represents the equivalent heat storage coefficient on the hot water storage tank side; This indicates the target water supply status of the hot water storage tank in the kth allocation cycle; This indicates the current heat storage status of the hot water storage tank. When the current heat storage status of the hot water storage tank is lower than the target water supply status, and the heat exchange side has the necessary receiving capabilities, The corresponding allowable condensate heat reception amount is allocated to the high-grade receiving path. When the hot water storage tank is nearing the target water supply state, or when the heat storage and exchange side no longer has the conditions to continue receiving heat, Reduce until the new allocation of high-quality receiving paths is blocked.
[0045] The upper limit for low-grade heat absorption is determined based on the remaining temperature rise margin of the pool water relative to the target constant temperature range. Unlike hot water storage tanks, pool water is constrained by the target constant temperature range, return water temperature changes, and pool water thermal inertia when receiving condensation heat, and cannot be allocated solely based on the amount of heat that can be absorbed. The remaining temperature rise margin represents the space within which the pool water can continue to absorb condensation heat at a low grade and low rate, provided that the target constant temperature control requirements are not exceeded.
[0046] In one implementation, the upper limit for the disposal of low-grade pool water within the k-th allocation cycle is expressed as:
[0047] in, This represents the upper limit for the low-grade water quality of the pool during the k-th allocation cycle; This represents the equivalent heat capacity coefficient on the water side of the swimming pool. This indicates the upper limit of the target constant temperature range for the pool water; This indicates the current temperature of the pool water. When the current temperature of the pool water is within the target constant temperature range but there is still an allowable temperature rise, this indicates the appropriate temperature. This corresponds to the allowable condensate heat absorption capacity allocated to the low-grade absorption path. When the pool water is close to the upper limit of the target constant temperature range, or when the return water temperature response indicates that continued absorption may cause the constant temperature range to be exceeded, Reduce, until the new allocation of low-grade waste disposal paths is blocked.
[0048] In the above formula and The value is determined based on the water volume, heat exchange capacity, equivalent heat capacity, or on-site calibration results of the engineering object, and is not limited to a fixed value. Through the above processing, the high-temperature receiving capacity of the hot water storage tank and the low-speed absorption capacity of the pool water are converted into adjustable condensation heat. Constraints on heat sink reception under the same measurement scale.
[0049] S103, Forming a heat sink constraint that is deducted periodically within the prediction window.
[0050] A prediction window is established covering the current allocation cycle and at least one subsequent allocation cycle. This prediction window is used to accommodate the adjustable condensation heat, the upper limit for high-grade reception, the upper limit for low-grade consumption, the feasible path region, the restricted allocation sequence, and the first allocation residual. The length of the prediction window is, but is not limited to, determined based on the scheduling cycle of the water world's heating and cooling source system, the thermal inertia of the hot water storage tank, the isothermal response speed of the swimming pool water, or the controller's calculation cycle.
[0051] Within the prediction window, the high-grade receiving upper limit and the low-grade consumption upper limit are converted into heat sink constraints that are deducted periodically. Let the prediction window consist of N allocation periods starting from the current period k, and let the i-th prediction period be denoted as k+i. For a high-grade receiving path, its remaining receiving constraint within the prediction period k+i is expressed as:
[0052] Where j = 0, 1, ..., i-1; This represents the high-grade remaining receiving constraint corresponding to the prediction period k+i within the prediction window established in the current period k. This indicates that the condensation heat in the preceding cycle of the forecast window has been allocated to the high-grade receiving path.
[0053] For the low-grade absorption path, its remaining absorption constraint within the prediction period k+i is expressed as:
[0054] Where j = 0, 1, ..., i-1; This indicates the low-grade residual consumption constraint corresponding to the prediction period k+i; This indicates the condensation heat that has been allocated to the low-grade heat dissipation path in the preceding cycle of the forecast window.
[0055] when When the minimum reception requirement for a high-quality reception path is lower than the minimum requirement for such a path, any new allocation of a high-quality reception path is blocked within the prediction period k+i. When the load is lower than the minimum load requirement of the low-grade load disposal path, the new allocation of the low-grade load disposal path is blocked within the prediction period k+i.
[0056] Through the aforementioned periodic deduction process, the high-grade receiving limit and the low-grade consumption limit are no longer the switching thresholds for the current period, but rather heat sink constraints that continuously change within the prediction window as the allocated amount has been arranged. These heat sink constraints are then incorporated into the process of calculating subsequent restricted allocation sequences.
[0057] S104. Establish the feasible path region.
[0058] Before determining the constrained allocation sequence, a path feasibility region is established based on the temperature grade of the adjustable condensing heat, the upper limit for receiving high-grade heat, the upper limit for absorbing low-grade heat, and the temperature-raising capacity of the two-stage temperature gradient heat pump. The path feasibility region is used to limit which paths can receive condensing heat in each allocation cycle within the prediction window, and the range of condensing heat that each path can receive.
[0059] For a prediction period k+i, the feasible region of the path is represented as:
[0060] in, This represents the feasible region of the path corresponding to the prediction period k+i within the prediction window established in the current period k. Indicates a high-quality receiving path; Indicates the low-grade waste disposal pathway; This indicates a restricted allocation path.
[0061] When the temperature grade of the adjustable condensing heat meets the requirements for heat storage reception, or the grade difference can be supplemented by a two-stage temperature gradient heat pump, and When the minimum reception requirement is met, Write the path feasible field. When If the temperature rise of the secondary temperature-controlled heat pump is insufficient to compensate for the grade difference, the high-grade receiving path will be restricted or blocked during the corresponding allocation cycle.
[0062] when When the minimum absorption requirements are met, and the pool water is still within the allowable temperature rise range, Write the feasible path domain. When the pool water is close to the upper limit of the target constant temperature range or the return water temperature response indicates that continued disposal may cause the constant temperature range to be exceeded, the low-grade disposal path is restricted or blocked within the corresponding allocation cycle.
[0063] Restricted allocation path This is used to receive surplus condensate heat that does not meet the feasibility conditions of high-grade receiving paths and low-grade absorption paths. A restricted distribution path does not mean that condensate heat is arbitrarily discharged, but rather that the allocation of condensate heat into the heat sink is limited within the current forecast window, or its proportion entering the heat sink is reduced, to prevent high-grade receiving in hot water storage tanks from exceeding the limits or low-grade absorption in swimming pools from exceeding the limits.
[0064] S105. Find the restricted allocation sequence.
[0065] Within the prediction window, using adjustable condensing heat, periodically deducted heat sink constraints, and path feasibility region as inputs, a constrained allocation sequence of adjustable condensing heat is obtained among the high-grade receiving path, low-grade consumption path, and restricted allocation path. The constrained allocation sequence includes the path selection results and path allocation amounts corresponding to each allocation cycle within the prediction window.
[0066] For the prediction period k+i, the distribution relationship of the adjustable condensation heat among the three types of paths is expressed as:
[0067] in, This represents the adjustable condensation heat within the prediction period k+i; This indicates the heat allocated to the high-grade receiving path; This represents the heat allocated to low-grade heat dissipation pathways; This represents the amount of heat entering the restricted distribution path.
[0068] The corresponding constraints are:
[0069]
[0070]
[0071] when When the path feasibility field is not written, let ;when When the path feasibility field is not written, let Through this process, path constraints in the feasible region are written into the allocation sequence retrieval procedure.
[0072] When determining the constrained allocation sequence, the amount of unabsorbed condensed heat, the amount of heat sink exceeding the limit, and the cost of path switching are used together as the evaluation criteria for the sequence. The amount of unabsorbed condensed heat is used to characterize the portion of the adjustable condensed heat that fails to enter the high-grade receiving path or the low-grade absorption path; the amount of heat sink exceeding the limit is used to characterize the extent to which the allocation result exceeds the upper limit of the high-grade receiving path or the upper limit of the low-grade absorption path; the cost of path switching is used to characterize the impact of frequently switching between high-grade receiving paths, low-grade absorption paths, or constrained allocation paths within adjacent allocation cycles on the stability of system operation.
[0073] The sequence evaluation results of candidate path allocation combinations within the prediction window are expressed as follows:
[0074] Where i = 0, 1, ..., N-1; J represents the sequence evaluation result of candidate assignment combinations within the prediction window; This represents the amount of condensation heat that has not been absorbed within the prediction period k+i; This indicates the amount of heat sink exceeding the limit; α represents the cost of path switching; α, β, and γ represent the weight coefficients of the corresponding evaluation items, which are determined based on the constraints of the water world cold and heat source system on condensation heat utilization, heat sink boundary control, and path switching stability.
[0075] The system selects the path allocation combination that satisfies the feasible region and heat sink constraints from the candidate allocation combinations as the restricted allocation sequence, ensuring that J satisfies the preset convergence condition. The restricted allocation sequence is expressed as:
[0076] in, This represents the restricted allocation sequence established in the current allocation period k; , , These represent the allocation amounts of the selected high-quality receiving path, low-quality absorption path, and restricted allocation path within the prediction period k+i, respectively.
[0077] S106. Execute the first allocation result of the current allocation cycle.
[0078] From restricted allocation sequence The first item corresponding to the current allocation cycle is extracted as the execution allocation result. Subsequent allocation results within the prediction window, excluding the first item, are not directly issued for execution. Instead, they are re-predicted in the next allocation cycle based on the new heat response, heat sink response, and the residual of the first item allocation.
[0079] The first execution result is represented as:
[0080] in, This indicates the first allocation result actually issued in the current allocation cycle; , , These represent the heat allocated to the high-grade receiving path, low-grade consumption path, and restricted allocation path in the current cycle, respectively.
[0081] when Furthermore, when a temperature increase is required, a temperature increase entry label is generated, and linkage operating parameters are established between the secondary temperature gradient heat pump and the heat storage heat exchange side. These linkage operating parameters are used to enable the secondary temperature gradient heat pump to increase the temperature of the condensed heat, and to allow the increased condensed heat to enter the hot water storage tank side.
[0082] when When no temperature increase is required, a thermal storage receiving tag is generated, and receiving operation parameters are established on the thermal storage heat exchange side. These receiving operation parameters are used to allow condensed heat to enter the hot water storage tank side, and the amount or proportion of heat received is limited according to the initial allocation result.
[0083] when At that time, a pool heat dissipation label is generated, and limiting operating parameters are established for the pool's heat exchange side. These limiting operating parameters are used to ensure that condensation heat enters the pool water heat exchange side in a manner that does not exceed the upper limit of low-grade heat dissipation, thus preventing the pool water from exceeding the target constant temperature range due to concentrated condensation heat entering the water.
[0084] when Furthermore, when the high-grade receiving path and low-grade disposal path do not meet the conditions for new allocation, a recycling-restricted tag is generated, restricting the new allocation of condensed heat into the heat sink side in the current cycle. The recycling-restricted tag is used to indicate that it is not suitable to continue to allocate to the high-grade receiving path or low-grade disposal path within the current prediction window, rather than indicating that the condensed heat must enter a fixed discharge path.
[0085] S107. Form the first term allocation residual and correct the next prediction window.
[0086] After the initial allocation result is executed, the temperature response of the heat sink is obtained. A high-grade receiving residual is generated based on the temperature response of the hot water storage tank, and a low-grade absorption residual is generated based on the temperature response of the pool water. The high-grade receiving residual characterizes the deviation between the execution result of the high-grade receiving path and the initial allocation result; the low-grade absorption residual characterizes the deviation between the execution result of the low-grade absorption path and the initial allocation result.
[0087] High-grade receiving residuals are expressed as:
[0088] in, Indicates high-grade receiving residual; This indicates the actual amount received by the hot water storage tank based on the temperature response after execution. This indicates the amount of heat allocated to the high-grade receiving path in the first item.
[0089] The residual of low-grade waste disposal is expressed as:
[0090] in, This indicates the residual value of low-grade waste disposal; This represents the actual amount of water absorbed by the pool, calculated based on the temperature response after implementation. This indicates the amount of heat allocated to the low-grade heat dissipation pathway in the first item.
[0091] when This indicates that when the actual reception of hot water from the storage tank is insufficient, the upper limit of high-grade reception in the next forecast window should be lowered, or the path switching cost of the high-grade reception path should be increased. The upper limit of high-grade reception in the next forecast window is expressed as follows:
[0092] in, Indicates the upper limit of high-quality reception used in the next prediction window; This represents the correction factor for high-grade receiving residuals. Because... It is negative when actual reception is insufficient, so this formula is used to reduce the high-quality reception limit of the next prediction window.
[0093] When the low-grade water quality retention residual indicates that the pool water temperature rise exceeds the allowable variation, the low-grade water quality retention limit for the next forecast window is lowered. The low-grade water quality retention limit for the next forecast window is expressed as follows:
[0094] in, This indicates the upper limit for low-grade waste disposal to be used in the next forecast window; This represents the correction factor for the residual of low-grade waste disposal; This indicates the portion of the pool water that exceeds the allowable temperature change.
[0095] When the execution feedback indicates that the path action is incomplete, the corresponding residual is marked as an execution residual, and this execution residual is prevented from directly correcting the heat sink receiving limit. The incomplete path action includes the execution side not allocating the result action according to the first item, the heat exchange side's execution status not meeting requirements, or missing feedback from the execution side. The execution residual is not directly substituted. or Instead of correcting the formula, it is used to increase the path switching cost of the corresponding path or trigger execution-side checks to avoid misjudging execution-side action anomalies as insufficient heat sink receiving capacity.
[0096] Through the processing in this embodiment, the current allocation cycle only executes the first item of the restricted allocation sequence. Subsequent allocation cycles re-form the prediction window and restricted allocation sequence based on the new operating response and the residual of the first item allocation. This allows the distribution process of condensation heat between the two heterogeneous heat sinks—the hot water storage tank and the swimming pool water—to be continuously corrected according to the actual receiving conditions.
[0097] Example 2: Water World Condensation Heat Rolling Prediction System This embodiment provides a water world condensation heat rolling prediction system for executing the water world condensation heat rolling prediction method described in Embodiment 1. The system includes a heat response acquisition terminal, a heat sink response acquisition terminal, an execution feedback acquisition terminal, a rolling prediction controller, a high-grade receiving execution side, a low-grade absorption execution side, and a restricted allocation execution side.
[0098] The heat response acquisition terminal is communicatively connected to the condensing heat recovery loop and the refrigeration-side operation loop, and is used to provide synchronized heat response and refrigeration-side operation response to the rolling predictive controller. The data provided by the heat response acquisition terminal is not directly used as operating parameters of the heat source and cold source, but rather as input for the rolling predictive controller to confirm the adjustable condensing heat.
[0099] The heat sink response acquisition terminal is communicatively connected to the hot water storage tank and the pool water body, and is used to provide heat sink responses to the rolling predictive controller. The heat sink response on the hot water storage tank side is used to form the high-grade receiving upper limit, and the heat sink response on the pool water body side is used to form the low-grade absorption upper limit. After the high-grade receiving upper limit and the low-grade absorption upper limit are entered into the rolling predictive controller, they are converted into heat sink constraints that are deducted periodically within the prediction window.
[0100] The rolling predictive controller is communicatively or controllably connected to the heat response acquisition terminal, heat sink response acquisition terminal, execution feedback acquisition terminal, high-grade receiving execution side, low-grade consumption execution side, and restricted allocation execution side. The rolling predictive controller stores the prediction window, heat sink constraints, path feasible region, restricted allocation sequence, and first-term allocation residual, and updates the above data based on the input response of the current allocation cycle.
[0101] The high-grade receiving execution side includes a thermal storage and heat exchange side and a secondary temperature-raising side that can be linked with the thermal storage and heat exchange side. When the first allocation result issued by the rolling predictive controller points to the high-grade receiving path, the high-grade receiving execution side performs temperature-raising and tank entry processing or thermal storage receiving processing according to the corresponding operating parameters.
[0102] The low-grade heat dissipation execution side includes the pool heat exchange side. When the first allocation result issued by the rolling predictive controller points to the low-grade heat dissipation path, the low-grade heat dissipation execution side allows the condensation heat to enter the pool heat exchange side according to the limiting operating parameters, and limits the condensation heat entering the pool water to not exceed the low-grade heat dissipation constraint.
[0103] The restricted allocation execution side is used to perform restricted recovery processing. When the first allocation result points to a restricted allocation path, the restricted allocation execution side restricts the new allocation of condensed heat into the heat sink side in the current allocation cycle, or reduces the allocation ratio of condensed heat into the heat sink side. The restricted allocation execution side is not limited to a fixed discharge device; its function is to prevent condensed heat that does not meet the high-grade receiving conditions and low-grade dissipation conditions from being forcibly allocated to the heat sink side.
[0104] The execution feedback acquisition terminal is communicatively connected to the high-grade receiving execution side, the low-grade absorption execution side, and the limited allocation execution side, or to temperature response detection points and heat exchanger operating status detection points that can reflect the action results of the aforementioned execution sides. The execution feedback acquisition terminal is used to obtain the heat sink temperature response and execution status feedback after the execution of the first allocation result, and return them to the rolling predictive controller.
[0105] The rolling forecast controller generates the initial allocation residual based on the data returned by the execution feedback acquisition terminal. The initial allocation residual includes high-grade reception residual, low-grade absorption residual, and execution residual. Among them, the high-grade reception residual is used to correct the high-grade reception upper limit or the high-grade reception path switching cost in the next forecast window; the low-grade absorption residual is used to correct the low-grade absorption upper limit in the next forecast window; and the execution residual is used to indicate that the execution-side action is not completed and to prevent this type of residual from directly correcting the heat sink reception upper limit.
[0106] Therefore, the heat response acquisition terminal provides confirmation input for adjustable condensing heat, the heat sink response acquisition terminal provides input for the formation of heat sink constraints, the rolling prediction controller forms and issues the first allocation result of the current allocation cycle, and the execution feedback acquisition terminal returns the residual after the first execution to the rolling prediction controller, so that the system can complete the rolling correction in the next prediction window.
[0107] Example 3: Water World Condensation Heat Rolling Prediction Equipment This embodiment provides a water world condensation heat rolling prediction device for executing the water world condensation heat rolling prediction method described in Embodiment 1. The device includes a processor, a memory, and a data interface connected to the processor.
[0108] The data interface is used to receive the heat response, refrigeration side operation response, and post-execution heat sink temperature response of the condensing heat recovery loop, and to output cold and heat source operation parameters to the high-grade receiving execution side, low-grade dissipation execution side, or limited distribution execution side. The data interface includes, but is not limited to, wired communication interfaces, wireless communication interfaces, fieldbus interfaces, or industrial Ethernet interfaces that connect to building automation systems, cold and heat source station control cabinets, energy management platforms, or field controllers.
[0109] The memory is used to store computer programs and running task records. The running task records include at least the adjustable condensing heat of the current allocation cycle, the upper limit for high-grade reception, the upper limit for low-grade absorption, the prediction window, the restricted allocation sequence, the first allocation result, path labels, cold and heat source operating parameters, and the first allocation residual. The first allocation residual serves as the input for the correction of the next prediction window and does not directly replace the heat response or heat sink temperature response obtained again in the next allocation cycle.
[0110] The processor is configured to execute a computer program in the memory to obtain the heat response and refrigeration-side operating response of the condensing heat recovery loop through the data interface, and determine the adjustable condensing heat that can be allocated in the current cycle; form a high-grade receiving upper limit and a low-grade consumption upper limit based on the heat sink temperature response; form a heat sink constraint that is deducted periodically within the prediction window, and obtain a restricted allocation sequence; take only the first item in the restricted allocation sequence corresponding to the current allocation cycle as the execution allocation result, and output the corresponding cold and heat source operating parameters through the data interface; obtain the heat sink temperature response after execution, form the first item allocation residual, and correct the high-grade receiving upper limit, low-grade consumption upper limit, or path switching cost of the next prediction window.
[0111] The water-based condensation heat prediction equipment includes, but is not limited to, edge control devices independently installed in the control cabinet of the cold and heat source station, or computing nodes deployed in building automation systems or energy management platforms. The communication methods between the equipment and the water-cooled screw heat pump, the two-stage temperature gradient heat pump, the heat storage heat exchange side, and the pool heat exchange side include, but are not limited to, fieldbus, industrial Ethernet, wireless communication, or communication interfaces already configured in the building automation system.
[0112] In one embodiment, the memory also stores a computer program for performing the method described in Embodiment 1. When the computer program is executed by the processor, it performs functions such as determining adjustable condensation heat, forming upper limits for high and low grade receiving, deducting heat sink constraints in the prediction window, obtaining the restricted allocation sequence, executing the first item, and writing back the first item allocation residual.
[0113] In another embodiment, a computer-readable storage medium is also provided, wherein a computer program is stored therein, and when executed by a processor, the computer program implements the water world condensation heat rolling prediction method described in Embodiment 1.
[0114] Working principle and effects In summary, the working principle of this invention is as follows: First, the heat response in the condensation heat recovery loop is verified to correspond with the refrigeration side operation response, so that the condensation heat entering the distribution process comes from the confirmed effective refrigeration operation state; then, the heat storage margin of the hot water storage tank relative to the target water supply state is converted into a high-grade receiving upper limit, and the remaining temperature rise margin of the pool water relative to the target constant temperature range is converted into a low-grade absorption upper limit, and the two are unified into a heat sink constraint that can be deducted periodically within the prediction window; under the joint constraints of this heat sink constraint and the temperature raising capacity of the secondary temperature gradient heat pump, the restricted distribution sequence of condensation heat between the high-grade receiving path, the low-grade absorption path, and the restricted distribution path is obtained; during execution, only the first item in the restricted distribution sequence corresponding to the current allocation cycle is sent to the corresponding execution side, and after execution, the first item distribution residual is formed according to the heat sink temperature response, which is used to correct the next prediction window.
[0115] Through the above processing, the allocation of condensate heat is no longer determined solely based on fixed heat sink priority or the current water temperature threshold. Instead, it first confirms whether the condensate heat is valid for allocation, and then forms a limited allocation result based on the different receiving constraints of the hot water storage tank and the pool water. The high-grade receiving capacity of the hot water storage tank and the low-grade absorption capacity of the pool water are converted into the same prediction window, so that they are no longer used as independent state conditions in the judgment. The residual after the current allocation cycle is only used to correct the next prediction window, and does not directly replace the heat response and heat sink response obtained again in the next cycle. This allows the condensate heat allocation process to be adjusted in a rolling manner according to the actual receiving state of the heat sink, and reduces the risk of condensate heat entering the mismatched heat sink due to single-cycle judgment errors.
