Description

Technical Field

[0001] The present application relates to the technical field of temperature regulation, and particularly to a method, device, equipment and medium for building temperature regulation management. Background Art

[0002] In the field of architecture, temperature regulation is a key link to ensure the comfort of the indoor environment. With the development of society and the improvement of people's living quality, the demand for precise temperature control in buildings is increasing day by day. Good temperature regulation can not only create a comfortable living and working space for people, improve living and working efficiency, but also affect the energy consumption and operation cost of buildings to a certain extent. Effective temperature regulation technology helps to reduce energy waste and conforms to the concept of sustainable development.

[0003] Currently, in the management of building temperature regulation, the means adopted are often relatively single, and usually only one method is used for temperature regulation at the same time period, resulting in relatively high energy consumption. Moreover, when regulating temperature by each method, there are also many problems. For example, for air-conditioning units, they are often turned on and off only according to fixed time and simple temperature settings, lacking comprehensive consideration of the performance of the air-conditioning units themselves and environmental factors, resulting in low energy utilization efficiency of the air conditioners; similarly, in the management of heat pumps and water pumps, the situation where precise regulation cannot be achieved due to insufficient combination of the information of the equipment itself and the pipe network parameters often occurs, causing unnecessary waste of energy and unable to effectively reduce the overall energy consumption of the building. Summary of the Invention

[0004] In order to reduce the energy consumption in the process of temperature regulation, the present application provides a method, device, equipment and medium for building temperature regulation management.

[0005] In a first aspect, the present application provides a method for building temperature regulation management, adopting the following technical solutions: A method for building temperature regulation management includes: Obtaining the information of the air-conditioning units, working hours, environmental temperature and indoor temperature of the building; Determining the air-conditioning unit management strategy based on the air-conditioning unit information, the environmental temperature, the indoor temperature and the working hours; Obtaining the heat pump information; Determining the heat pump management strategy based on the indoor temperature and the heat pump information; Obtaining the actual water temperature of the main pipe network and the supply-return water pressure difference of the secondary pipe network; Determining the water pump management strategy based on the actual water temperature and the supply-return water pressure difference; Determining the building energy-saving strategy based on the air-conditioning unit management strategy, the heat pump management strategy and the water pump management strategy.

[0006] By adopting the above technical solution, when determining the air conditioner unit management strategy, not only the ambient temperature and the indoor temperature are considered, but also the air conditioner unit information and the working hours of the building are taken into account, improving the reliability of the air conditioner unit management strategy, thereby reducing the energy consumption during the temperature regulation process; by comprehensively regulating the building temperature through three methods of air conditioner, heat pump and water pump simultaneously, the excessive energy loss caused by a single regulation method is reduced, that is, the energy consumption during the temperature regulation process is further reduced.

[0007] Optionally, the working hours include the end time of work, and determining the air conditioner unit management strategy based on the air conditioner unit information, the ambient temperature, the indoor temperature and the working hours includes: Obtain the first historical temperature change data when the building is not undergoing temperature regulation, where the first historical temperature change data includes the historical indoor temperature, the historical outdoor temperature and the time stamp; Construct a temperature change prediction model based on the first historical temperature change data and a preset algorithm; Based on the ambient temperature, the indoor temperature and the temperature change prediction model, determine the second indoor temperature corresponding to stopping temperature regulation at each moment, where the second indoor temperature is the indoor temperature corresponding to the end time of work; Determine the moment when the second indoor temperature meets the preset room temperature requirement as the moment to stop temperature regulation; Determine the air conditioner operation period based on the working hours and the moment to stop temperature regulation; Determine the air conditioner unit management strategy based on the air conditioner operation period, the air conditioner unit information, the ambient temperature and the indoor temperature.

[0008] By adopting the above technical solution, by predicting the second indoor temperature corresponding to stopping temperature regulation at each moment and comparing the second indoor temperature with the preset room temperature requirement to obtain the moment to stop temperature regulation, it is possible to stop the air conditioner operation in advance on the premise of not overly affecting the indoor environment comfort, reducing the energy consumption during the temperature regulation process.

[0009] Optionally, determining the air conditioner unit management strategy based on the air conditioner operation period, the air conditioner unit information, the ambient temperature and the indoor temperature includes: Determine the air conditioner efficiency of each air conditioner based on the air conditioner unit information; Sort the air conditioners in descending order according to the air conditioner efficiency to obtain the first sorting result; Run simulations on various air conditioner startup strategies through the ambient temperature, the indoor temperature, and a thermal energy simulation tool to obtain temperature change conditions, where the temperature change conditions include timestamps and the predicted indoor temperature corresponding to each timestamp, and different air conditioner startup strategies correspond to different numbers of air conditioner startups; Determine a first score based on the temperature change conditions, a first target temperature, and a preset scoring rule; Determine a second score based on the air conditioner startup strategy and the preset scoring rule; Determine the strategy score of each air conditioner startup strategy based on the first score, the second score, and a preset weight; Determine an air conditioner unit management strategy based on the air conditioner operation period, the strategy score, and the air conditioner startup strategy.

[0010] By adopting the above technical solution, when determining the air conditioner unit management strategy, not only the temperature control effect (the first score) of each air conditioner startup strategy is considered, but also the energy consumption (the second score) of each air conditioner startup strategy is considered, improving the reliability of the air conditioner unit management strategy, thereby reducing the energy consumption during the temperature control process.

[0011] Optionally, the determining the heat pump management strategy based on the indoor temperature and the heat pump information includes: Determine the heat pump efficiency and the heat pump status of each heat pump based on the heat pump information, where the heat pump status includes an operating status and a shutdown status; Sort the heat pumps from high to low according to the heat pump efficiency to obtain a second sorting result; Compare the indoor temperature with the first target temperature; If the indoor temperature does not meet the first target temperature and the first duration exceeds a preset duration, determine the heat pumps to be started based on the second sorting result and the heat pump status, where the first duration is the duration for which the indoor temperature does not meet the first target temperature; If the indoor temperature meets the first target temperature and the second duration exceeds a preset duration, determine the heat pumps to be shut down based on the second sorting result and the heat pump status, where the second duration is the duration for which the indoor temperature meets the first target temperature; Determine the heat pump management strategy based on the heat pumps to be started or the heat pumps to be shut down.

[0012] By adopting the above technical solution, when heat pump adjustment is required, the heat pumps with high heat pump efficiency are preferentially operated, and the heat pumps with low heat pump efficiency are preferentially shut down, reducing the energy consumption during the temperature control process.

[0013] Optionally, the method further includes: Obtain the temperature change trend of the building; Determine the predicted indoor temperature for the next time period based on the temperature change trend; Adjust the first target temperature based on the indoor temperature, the predicted indoor temperature, and a preset rule.

[0015] Optionally, the determining the water pump management strategy based on the actual water temperature and the differential pressure between the supply and return water pressures includes: If the actual water temperature does not meet the second target temperature and there is a running frequency of an operating water pump that has not reached the maximum frequency, determine a water pump frequency increase strategy based on a preset frequency adjustment rule, where the operating water pump is the water pump currently in the operating state; If the running frequency of the operating water pump reaches the maximum frequency and the third continuous duration for which the actual water temperature does not meet the second target temperature reaches a preset duration, determine a water pump adding machine strategy based on the minimum frequency; If the actual water temperature meets the second target temperature, determine the water pump to be adjusted as the operating water pump with the longest running duration; If the running frequency of the water pump to be adjusted is greater than the minimum frequency, determine a water pump frequency decrease strategy based on the preset frequency adjustment rule; If the running frequency of the operating water pump reaches the minimum frequency and the fourth continuous duration for which the actual water temperature meets the second target temperature reaches a preset duration, determine a water pump reducing machine strategy based on the water pump to be adjusted; Determine a first-network water pump management strategy based on the water pump frequency increase strategy, the water pump adding machine strategy, the water pump frequency decrease strategy, and the water pump reducing machine strategy; Determine a second-network water pump management strategy based on the differential pressure between the supply and return water pressures; Determine the water pump management strategy based on the first-network water pump management strategy and the second-network water pump management strategy.

[0016] By adopting the above technical solution, when water pump adjustment is required, the running frequency of the water pump is given priority, and then starting or stopping the water pump is considered, reducing the damage to the water pump caused by frequent starting or stopping of the water pump, and reducing the energy consumption during the start-stop process of the water pump.

[0017] Optionally, the determining the second-network water pump management strategy based on the differential pressure between the supply and return water pressures includes: Calculate the differential pressure between the supply and return water and the target differential pressure through the PID adjustment algorithm to obtain the valve opening adjustment amount; Determine the secondary network water pump management strategy based on the valve opening adjustment amount and the magnitude relationship between the differential pressure between the supply and return water and the target differential pressure.

[0019] By adopting the above technical solution, when determining the air conditioning unit management strategy, not only the ambient temperature and the indoor temperature are considered, but also the air conditioning unit information and the working hours of the building are considered, improving the reliability of the air conditioning unit management strategy, thereby reducing the energy consumption during the temperature regulation process; by comprehensively regulating the building temperature through three methods of air conditioning, heat pump, and water pump, the excessive energy loss caused by a single regulation method is reduced, that is, the energy consumption during the temperature regulation process is further reduced.

[0027] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application.

For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this article generally represents an "or" relationship between the associated objects before and after, unless otherwise specified.

[0029] As Figure 1 shown, a building temperature regulation and management method, the main process of which is described as follows (Steps S101 to S107): Step S101, obtain the air-conditioning unit information, working hours, ambient temperature, and indoor temperature of the building.

[0030] Obtain the air conditioning unit information in the building and the working hours of the personnel in the building from the building staff. The air conditioning unit information includes, but is not limited to, the air conditioning number, air conditioning efficiency, air conditioning energy consumption, etc. The working hours include the start time and the end time of work. Obtain the ambient temperature for a preset future time period (the preset future time period is the time period between the current time and the end time of work) from the meteorological department, and obtain the indoor temperature from each temperature sensor in the building.

[0031] Step S102: Determine the air conditioning unit management strategy based on the air conditioning unit information, ambient temperature, indoor temperature, and working hours.

[0032] Specifically, determining the air conditioning unit management strategy based on the air conditioning unit information, ambient temperature, indoor temperature, and working hours includes: obtaining the first historical temperature change data when the building has not undergone temperature adjustment. The first historical temperature change data includes historical indoor temperature, historical outdoor temperature, and time stamps; constructing a temperature change prediction model based on the first historical temperature change data and a preset algorithm; determining the corresponding second indoor temperature for stopping temperature adjustment at each moment based on the ambient temperature, indoor temperature, and the temperature change prediction model. The second indoor temperature is the indoor temperature corresponding to the end time of work; determining the moment when the second indoor temperature meets the preset room temperature requirement as the moment to stop temperature adjustment; determining the air conditioning operation period based on the working hours and the moment to stop temperature adjustment; determining the air conditioning unit management strategy based on the air conditioning operation period, air conditioning unit information, ambient temperature, and indoor temperature.

[0033] In this embodiment, obtain the first historical temperature change data when the building has not undergone temperature adjustment (i.e., in the natural state) from the database or the staff. The first historical temperature change data includes the historical indoor temperature and historical outdoor temperature corresponding to each time stamp. Train the preset algorithm through the first historical temperature change data to obtain a temperature change prediction model. The temperature change prediction model can predict the indoor temperature at each moment in the preset future time period based on the ambient temperature in the preset future time period and the current indoor temperature.

[0034] Input the indoor temperature at a moment within a preset future time period and the ambient temperature after that moment within the preset future time period into the temperature change prediction model to obtain the indoor temperature corresponding to the end time of operation if the temperature adjustment stops at that moment, i.e., the second indoor temperature; determine the moment when the corresponding second indoor temperature meets the preset room temperature requirement (pre-set, not specifically limited here) as the temperature adjustment stop moment, that is, stop the temperature adjustment at the temperature adjustment stop moment, and the temperature in the building can also meet the user's needs by the end time of operation. The air conditioner operation period is the time period between the start time of work and the temperature adjustment stop moment; determine the air conditioner unit management strategy based on the air conditioner operation period, air conditioner unit information, ambient temperature, and indoor temperature. Among them, the preset algorithm can be a neural network algorithm or a support vector machine algorithm, which is not specifically limited here.

[0035] Further, determine the air conditioner unit management strategy based on the air conditioner operation period, air conditioner unit information, ambient temperature, and indoor temperature, including: determining the air conditioner efficiency of each air conditioner based on the air conditioner unit information; sorting the air conditioners from high to low according to the air conditioner efficiency to obtain the first sorting result; performing operation simulations on various air conditioner startup strategies through the ambient temperature, indoor temperature, and thermal energy simulation tool to obtain the temperature change situation, where the temperature change situation includes time stamps and the predicted indoor temperature corresponding to each time stamp. Different air conditioner startup strategies correspond to different air conditioner startup quantities; determining the first score based on the temperature change situation, the first target temperature, and the preset scoring rule; determining the second score based on the air conditioner startup strategy and the preset scoring rule; determining the strategy score of each air conditioner startup strategy based on the first score, the second score, and the preset weight; determining the air conditioner unit management strategy based on the air conditioner operation period, the strategy score, and the air conditioner startup strategy.

[0036] In this embodiment, find the air conditioner efficiency of each air conditioner from the air conditioner unit information, sort the air conditioners from high to low according to the air conditioner efficiency to obtain the first sorting result; the air conditioner startup strategy is to start the first air conditioner startup quantity of air conditioners in the first sorting result, input the ambient temperature, indoor temperature, and air conditioner startup strategy into the pre-configured thermal energy simulation tool for operation simulation to obtain the temperature change situation under various air conditioner startup strategies, and the temperature change situation is the predicted indoor temperature corresponding to each time stamp.

[0037] The preset scoring rule is a rule for scoring the temperature change situation and the energy consumption corresponding to the air conditioner startup strategy that has been determined in advance. The temperature change situation corresponding to each air conditioner startup strategy and the first target temperature (i.e., the target temperature that needs to be achieved in the building, which can be obtained from the staff) are scored through the preset scoring rule to obtain the first score corresponding to each air conditioner startup strategy. The air conditioner energy consumption of each air conditioner is found from the air conditioner unit information, and the total energy consumption of the air conditioners started in each air conditioner startup strategy is calculated. The total energy consumption is scored through the preset scoring rule to obtain the second score corresponding to each air conditioner startup strategy. The preset weights are obtained from the database. The preset weights include the first preset weight and the second preset weight. The strategy score of each air conditioner startup strategy = the first score of this air conditioner startup strategy × the first preset weight + the second score of this air conditioner startup strategy × the second preset weight. The air conditioner unit management strategy is to start the air conditioner according to the air conditioner startup strategy corresponding to the highest strategy score and the air conditioner operation time period. Among them, thermal energy simulation tools such as: EnergyPlus, TRNSYS, eQUEST, etc.

[0038] Step S103, obtain heat pump information.

[0039] Obtain heat pump information from the staff. The heat pump information includes but is not limited to heat pump efficiency, heat pump status, etc. The heat pump status includes the operating status and the shutdown status.

[0040] Step S104, determine the heat pump management strategy based on the indoor temperature and the heat pump information.

[0041] Specifically, determining the heat pump management strategy based on the indoor temperature and the heat pump information includes: determining the heat pump efficiency and heat pump status of each heat pump based on the heat pump information. The heat pump status includes the operating status and the shutdown status; sorting the heat pumps from high to low according to the heat pump efficiency to obtain the second sorting result; comparing the indoor temperature with the first target temperature; if the indoor temperature does not meet the first target temperature and the first duration exceeds the preset duration, then determine the heat pump to be started based on the second sorting result and the heat pump status. The first duration is the duration when the indoor temperature does not meet the first target temperature; if the indoor temperature meets the first target temperature and the second duration exceeds the preset duration, then determine the heat pump to be shut down based on the second sorting result and the heat pump status. The second duration is the duration when the indoor temperature meets the first target temperature; determine the heat pump management strategy based on the heat pump to be started or the heat pump to be shut down.

[0042] In this embodiment, the heat pump efficiency and the heat pump status of each heat pump are found from the heat pump information, and the heat pumps are sorted in descending order of heat pump efficiency to obtain a second sorting result. If the indoor temperature does not meet the first target temperature (if it is in the heating state at this time, the indoor temperature is less than the first target temperature when the indoor temperature does not meet the first target temperature; if it is in the cooling state at this time, the indoor temperature is greater than the first target temperature when the indoor temperature does not meet the first target temperature), and the first continuous duration during which the indoor temperature does not meet the first target temperature exceeds a preset duration (pre-set, not specifically limited here), then a new heat pump needs to be started at this time, and the heat pump with the highest heat pump efficiency and a shutdown status in the second sorting result is determined as the heat pump to be started; if the indoor temperature meets the first target temperature (if it is in the heating state at this time, the indoor temperature is greater than or equal to the first target temperature when the indoor temperature meets the first target temperature; if it is in the cooling state at this time, the indoor temperature is less than or equal to the first target temperature when the indoor temperature meets the first target temperature), and the second continuous duration during which the indoor temperature meets the first target temperature exceeds a preset duration, then the heat pump with the lowest heat pump efficiency and a running status in the second sorting result is determined as the heat pump to be shut down. The heat pump management strategy is to start the heat pump to be started or to turn off the heat pump to be shut down.

[0043] Except for the above two cases, there is no need to adjust the heat pump in other cases.

[0044] Specifically, the method further includes: obtaining the temperature change trend of the building; determining the predicted indoor temperature for the next time period based on the temperature change trend; and adjusting the first target temperature based on the indoor temperature, the predicted indoor temperature, and a preset rule.

[0045] In this embodiment, the temperature change trend of the building within a day is obtained from the database or from the staff. The temperature change trend is the indoor temperature of the building at each time period (for example: one hour) in a day. The indoor temperature of the next time period after the current moment in the temperature change trend is determined as the predicted indoor temperature. The room temperature change value = predicted indoor temperature - current indoor temperature. The preset rule is obtained from the database. The preset rule is a rule for adjusting the first target temperature according to the room temperature change value. For example: in the heating state, if the room temperature change value is greater than 0, the first target temperature is increased; if the room temperature change value is less than 0, the first target temperature is decreased. By adjusting the first target temperature in real time, the indoor temperature can be made to reach a suitable temperature value as soon as possible in advance.

[0046] Step S105: Obtain the actual water temperature of the main pipe network and the pressure difference between the supply and return water of the secondary pipe network.

[0047] The long-distance pipeline network is used to supply heating and cooling to users. The long-distance pipeline network includes a main pipeline network and a secondary pipeline network. The cooling / heating end is connected to multiple transfer stations through multiple main pipeline networks, and each transfer station is connected to multiple buildings through multiple secondary pipeline networks.

[0048] Temperature sensors are installed on each main pipeline network to obtain the actual water temperature of each main pipeline network. At least two pressure sensors are installed on a secondary pipeline network to detect the water supply pressure and return water pressure of the secondary pipeline network, obtain the water supply pressure and return water pressure of the secondary pipeline network from each pressure sensor, and calculate the pressure difference between the supply and return water based on the water supply pressure and return water pressure.

[0049] Step S106: Determine the water pump management strategy based on the actual water temperature and the pressure difference between the supply and return water.

[0050] Specifically, determining the water pump management strategy based on the actual water temperature and the pressure difference between the supply and return water includes: if the actual water temperature does not meet the second target temperature and there is an operating frequency of an operating water pump that has not reached the maximum frequency, then determine the water pump frequency increase strategy based on the preset frequency adjustment rule, and the operating water pump is the water pump currently in the operating state; if the operating frequency of the operating water pump reaches the maximum frequency and the third continuous duration during which the actual water temperature does not meet the second target temperature reaches the preset duration, then determine the water pump addition strategy based on the minimum frequency; if the actual water temperature meets the second target temperature, then determine the water pump with the longest operating duration as the water pump to be adjusted; if the operating frequency of the water pump to be adjusted is greater than the minimum frequency, then determine the water pump frequency decrease strategy based on the preset frequency adjustment rule; if the operating frequency of the water pump to be adjusted reaches the minimum frequency and the fourth continuous duration during which the actual water temperature meets the second target temperature reaches the preset duration, then determine the water pump reduction strategy based on the water pump to be adjusted; determine the first-network water pump management strategy based on the water pump frequency increase strategy, the water pump addition strategy, the water pump frequency decrease strategy, and the water pump reduction strategy; determine the second-network water pump management strategy based on the pressure difference between the supply and return water; determine the water pump management strategy based on the first-network water pump management strategy and the second-network water pump management strategy.

[0051] In this embodiment, the operating frequency of the running water pump and the second target temperature are obtained from the database or from the staff. The second target temperature is the target temperature that the main pipe network needs to reach, which is preset by the staff. If the actual water temperature does not meet the second target temperature (for example: when the temperature control state is the cooling state, the actual water temperature being greater than the second target temperature means the actual water temperature does not meet the second target temperature; when the temperature control state is the heating state, the actual water temperature being less than the second target temperature means the actual water temperature does not meet the second target temperature), and there is an operating frequency of the running water pump that has not reached the highest frequency (preset, not specifically limited here), then a preset frequency adjustment rule is obtained from the database. The water pump frequency increase strategy is to increase the frequency of the running water pumps that have not reached the highest frequency according to the preset frequency adjustment rule. The preset frequency adjustment rule is, for example: increase the operating frequency of the running water pumps that have not reached the highest frequency by 1HZ every 1 minute until the actual water temperature is equal to the second target temperature or the operating frequencies of all running water pumps have reached the highest frequency.

[0052] If the operating frequencies of all running water pumps have reached the highest frequency, and the third continuous duration during which the actual water temperature does not meet the second target temperature reaches the preset duration, then the water pump addition strategy is to start a new water pump and operate the newly started water pump at the lowest frequency (preset, not specifically limited here).

[0053] If the actual water temperature meets the second target temperature (for example: when the temperature control state is the cooling state, the actual water temperature being less than the second target temperature means the actual water temperature meets the second target temperature; when the temperature control state is the heating state, the actual water temperature being greater than the second target temperature means the actual water temperature meets the second target temperature), then the running duration of each running water pump is obtained from the staff, and the running water pump with the longest running duration is determined as the water pump to be adjusted. If the operating frequency of the water pump to be adjusted is greater than the lowest frequency, then the water pump frequency reduction strategy is to reduce the frequency of the water pump to be adjusted according to the preset frequency adjustment rule. The preset frequency adjustment rule is, for example: reduce the operating frequency of the water pump to be adjusted by 1HZ every 1 minute until the actual water temperature is equal to the second target temperature or the operating frequency of the water pump to be adjusted reaches the lowest frequency.

[0054] If the operating frequency of the water pump to be adjusted reaches the lowest frequency, and the fourth continuous duration during which the actual water temperature meets the second target temperature reaches the preset duration, then the water pump reduction strategy is to turn off the water pump to be adjusted.

[0055] The water pump frequency increase strategy, the water pump addition strategy, the water pump frequency reduction strategy, and the water pump reduction strategy are jointly determined as the management strategy for the water pumps in one network. Except for the above situations, there is no need to adjust the number and operating frequency of the water pumps in the main pipe network in other situations.

[0056] Based on the differential pressure between the supply and return water, the management strategy for the water pumps in the second network is determined; the management strategy for the water pumps in one network and the management strategy for the water pumps in the second network are jointly determined as the water pump management strategy.

[0057] Further, a secondary network water pump management strategy is determined based on the supply - return water pressure difference, including: calculating the supply - return water pressure difference and the target pressure difference through a PID regulation algorithm to obtain the valve opening adjustment amount; determining the secondary network water pump management strategy based on the valve opening adjustment amount and the magnitude relationship between the supply - return water pressure difference and the target pressure difference.

[0058] In this embodiment, the supply - return water pressure difference and the target pressure difference (pre - set, not specifically limited here) are calculated through a PID regulation algorithm to obtain the valve opening adjustment amount. The valve opening adjustment direction is determined according to the magnitude relationship between the supply - return water pressure difference and the target pressure difference. If the supply - return water pressure difference is less than the target pressure difference, the valve opening adjustment direction is to increase the valve opening; if the supply - return water pressure difference is greater than the target pressure difference, the valve opening adjustment direction is to decrease the valve opening. The secondary network water pump management strategy is to adjust the valve according to the valve opening adjustment direction and the valve opening adjustment amount. Among them, the PID regulation algorithm is a commonly used technical means in this field and will not be elaborated here.

[0059] Step S107: Determine a building energy - saving strategy based on the air - conditioner unit management strategy, the heat pump management strategy, and the water pump management strategy.

[0060] The air - conditioner unit management strategy, the heat pump management strategy, and the water pump management strategy are jointly determined as the building energy - saving strategy.
