Description

Technical Field

[0001] The present application relates to the field of air conditioning technology, and in particular to a ground source heat pump control method, device, air conditioning equipment and medium. Background Art

[0002] A geothermal heat pump is a heating and air-conditioning system that uses shallow geothermal resources (also known as geothermal energy) on the earth's surface as a source of cold and heat for energy conversion. It mainly utilizes the relatively constant temperature characteristics of underground soil, groundwater, surface water, etc., and transfers low-temperature heat energy to high-temperature heat energy by inputting a small amount of electrical energy, thereby achieving the purpose of cooling in summer and heating in winter.

[0003] However, ground-source heat pumps are greatly affected by geology. In cold countries and regions, there is a common problem of underground soil balance compensation due to the imbalance of indoor cold / heat loads in buildings throughout the year. For example, in cold northern regions, since the winter heat load of buildings is much greater than the summer cold load, the heat absorbed from the underground soil in winter is much greater than the heat discharged into the soil in summer, that is, the summer cold load of the building is much lower than the winter heat load. Specifically, less heat is discharged to the soil in summer, and more heat is absorbed from the soil in winter. Therefore, the use of ground-source heat pumps for energy conversion can easily cause cold / heat imbalance in the underground soil, and the ground temperature begins to drop, resulting in low operating efficiency of the ground-source heat pump, unstable operation of the main unit, and indoor heating that cannot meet the requirements, which affects the temperature recovery of the underground soil.

[0069] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments.

[0070] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0071] Specifically, the ground source heat pump in the existing related technology usually adopts the summer auxiliary heat source method, such as based on renewable energy such as solar energy and air energy, to heat the soil by heat source tower supplementation method to make up for the low temperature imbalance caused by the imbalance of cold and heat loads in winter and summer of the building. When supplementing heat, the heat source tower supplementation and the air conditioning system are generally not enabled at the same time, or the heat source tower is operated full-time in the hottest month for supplementary heat. Since the soil temperature is lower after taking heat in winter, it can generally be used for direct cooling by air conditioning in summer; or, since the lower soil temperature provides a lower cooling water inlet temperature for the refrigeration host, the lower cooling water inlet temperature can improve the operating energy efficiency of the host. However, the traditional heat source tower supplementation method cannot effectively utilize the low-temperature soil source high-grade cold source in summer, and there is a problem of low operating energy efficiency of the ground source heat pump.

[0072] Based on the above, the embodiments of the present application provide a ground source heat pump control method, device, air-conditioning equipment and medium. The total amount of heat re-injected by the ground source heat pump during the cooling time is determined based on the historical record information corresponding to the ground source heat pump, and the heat supplement load for each time period is calculated based on the total amount of heat re-injected and combined with the load forecast data corresponding to the ground source heat pump to obtain the predicted heat supplement corresponding to the current time period. Subsequently, the heat supplement load is corrected based on the predicted heat supplement and combined with the data collection information corresponding to the ground source heat pump to obtain the amount of heat to be supplemented by the ground source heat pump in the current time period, and the ground source heat pump is controlled to supplement heat in the current time period based on the amount of heat to be supplemented, so as to ensure the stable operation of the ground source heat pump and improve the operating energy efficiency of the ground source heat pump on the premise of achieving the cold and heat balance of the soil throughout the year.

[0073] Figure 1 A schematic diagram of the steps of a ground source heat pump control method provided in an embodiment of the present application. Figure 1As shown, the ground source heat pump control method provided in the embodiment of the present application includes the following steps:

[0074] Step 110, determining the total heat recharged by the ground source heat pump during the cooling time based on the historical record information corresponding to the ground source heat pump;

[0075] Among them, the historical record information corresponding to the geothermal heat pump refers to the information recorded for the geothermal heat pump, such as various information recorded after the geothermal heat pump is put into operation, and specifically may include the soil heat extraction record information of the geothermal heat pump, and the soil heat extraction record information can be used to determine the total heat extracted from the soil by the geothermal heat pump in the previous heating season; the cooling time refers to the cooling time of energy supply systems such as air conditioning. For example, in areas with hot summers and cold winters, summer is used as the cooling season throughout the year, and the months included in the cooling season can be used as the cooling time of the geothermal heat pump; the total heat re-injected by the geothermal heat pump during the cooling time refers to the total heat that the geothermal heat pump needs to be re-injected into the soil during the cooling time. For example, the total heat that the geothermal heat pump needs to be re-injected into the soil during the cooling season throughout the year can be determined as the total heat re-injected by the geothermal heat pump during the cooling time.

[0076] Specifically, after the ground source heat pump is started, the embodiment of the present application can obtain the historical record information corresponding to the ground source heat pump, so as to read the total heat extracted from the soil by the ground source heat pump in the previous heating season from the historical record information, and then the total heat extracted from the soil by the ground source heat pump in the previous heating season can be used to determine the total heat re-injected by the ground source heat pump during the cooling time; the total re-injected heat can be composed of two parts, one is the heat generated by the air-conditioning cooling load and related equipment for refrigeration, and the other is the heat generated by auxiliary heating equipment such as heat source towers.

[0077] Step 120, based on the total recharged heat, combined with the load forecast data corresponding to the ground source heat pump, the heat supplement load of each time period is calculated to obtain the forecast heat supplement corresponding to the current time period;

[0078] Among them, the load prediction data corresponding to the ground source heat pump refers to the load prediction data generated by load prediction based on the maximum heat storage capacity of the ground source heat pump equipment, which may specifically include but not be limited to the annual building load prediction data, air conditioning load data, etc.; the building load prediction data refers to the cooling and heating load prediction based on the function of the building, and the size of the load value indicates the heat required for air conditioning refrigeration and heating, which can usually be determined based on many parameters such as the maintenance structure material of the building, outdoor meteorological parameters, and the number of indoor personnel. The embodiment of the present application does not limit this. The air conditioning load data may include the air conditioning load information generated by prediction based on the detected meteorological parameters, such as the air conditioning load generated by prediction through load prediction software, and the air conditioning load is related to the detected meteorological parameters; the meteorological parameters can be used to determine the maximum heating capacity during the heating period, which may specifically include but not be limited to the outdoor dry bulb temperature, wet bulb temperature, etc.; the maximum heating capacity refers to the maximum heat storage capacity of the auxiliary heating equipment such as the heat source tower in the ground source heat pump itself according to the change of outdoor meteorological parameters.

[0079] Specifically, the embodiment of the present application can divide the entire cooling time into multiple heating supplementary periods in advance according to the load forecast number, and can determine the air conditioning forecast load of each heating supplementary period according to the load forecast number, so as to calculate the amount of supplementary heat required to be generated by the auxiliary heating equipment in each heating supplementary period according to the air conditioning forecast load and the total heat of the return injection according to each heating supplementary period, and then calculate the amount of supplementary heat required to be generated by the auxiliary heating equipment in the current period according to the air conditioning forecast load in the current period, and then calculate the actual amount of heat required to be generated in the current period as the forecasted amount of supplementary heat corresponding to the current period. Among them, the current period refers to the current heating supplementary period.

[0080] Step 130, based on the predicted supplementary heat amount, combined with the data collection information corresponding to the ground source heat pump, a supplementary heat load correction is performed to obtain the heat to be supplemented by the ground source heat pump in the current period;

[0081] Among them, the data collection information corresponding to the ground source heat pump refers to the various information parameters collected by the data collection module for the ground source heat pump. The information parameters may specifically include but are not limited to the meteorological parameters detected corresponding to each detection time, the water inlet temperature entering the auxiliary heating equipment, the detected soil temperature, the water flow rate of the refrigerant medium used by the auxiliary heating equipment, etc. The embodiment of the present application does not limit this.

[0082] Specifically, after determining the predicted heating amount corresponding to the current time period, the embodiment of the present application can determine the heating amount already generated in the current time period and the actual heating amount in the previous heating stage according to the data acquisition information corresponding to the ground source heat pump, and can compare the actual heating amount in the previous heating stage with the predicted heating amount corresponding to the previous heating stage to determine the heating difference in the previous heating stage, so as to utilize the heating difference in the previous heating stage and perform heating load correction in combination with the heating amount already generated in the current time period, thereby determining the amount of heat required for heating by the ground source heat pump in the current time period as the heat to be supplemented by the ground source heat pump in the current time period, so that the ground source heat pump can be controlled to perform heating according to the heat to be supplemented later.

[0083] Step 140: Control the ground source heat pump to supplement heat in the current time period according to the heat to be supplemented.

[0084] In this step, the operation of the auxiliary heating equipment in the ground source heat pump can be controlled according to the heat to be supplemented in the current time period and the air-conditioning load in the current stage, so as to supplement the heat through the heat generated by the operation of the auxiliary heating equipment in the ground source heat pump and the heat generated by the air-conditioning load. For example, the heat generated by the operation of the auxiliary heating equipment in the ground source heat pump and the heat generated by the air-conditioning load are injected into the soil through the buried pipes of the ground source heat pump to complete the heat required to be injected into the soil in the current time period, thereby realizing the time-divided heat storage control method of the ground source heat pump, avoiding the influence of weather changes, long-term operation of the ground source heat pump system, large deviation in heat storage capacity, inflexible equipment adjustment, etc., and realizing the optimal operation of the heat storage mode.

[0085] It can be seen that the ground source heat pump control method provided by the present application determines the total heat re-injected by the ground source heat pump during the cooling time based on the historical record information corresponding to the ground source heat pump, and calculates the heat supplement load for each time period based on the total heat re-injected and combined with the load forecast data corresponding to the ground source heat pump to obtain the predicted heat supplement corresponding to the current time period, and then based on the predicted heat supplement and combined with the data acquisition information corresponding to the ground source heat pump, the heat supplement load is corrected to obtain the amount of heat to be supplemented by the ground source heat pump in the current time period, and the ground source heat pump is controlled to supplement heat in the current time period based on the heat to be supplemented in the current time period, thereby realizing the time-divided heat storage control method of the ground source heat pump, and then realizing the year-round hot and cold balance control of the ground source heat pump, solving the problem of cold / heat imbalance of underground soil caused by energy conversion using ground source heat pumps in the existing related technologies.

[0086] In one embodiment of the present application, the cooling time such as summer can be divided into several time periods according to the changes in meteorological parameters as supplementary heating time periods, and the supplementary heating load of each time period can be calculated to determine the amount of supplementary heat required to be generated by auxiliary heating equipment such as a heat source tower in each supplementary heating time period, so as to perform a forecast calculation based on the amount of supplementary heat required to be generated by the auxiliary heating equipment in each supplementary heating time period and the amount of heat corresponding to the predicted load of the air conditioner, thereby determining the amount of heat required to be generated in accordance with the forecast for each supplementary heating time period as the predicted supplementary heat corresponding to the supplementary heating time period. Optionally, the embodiment of the present application calculates the supplementary heating load for each time period based on the total heat of the reinjection and in combination with the load forecast data corresponding to the ground source heat pump to obtain the predicted supplementary heat corresponding to the current time period, which can specifically include the following sub-steps:

[0087] Sub-step S11, obtaining the load forecast data;

[0088] Sub-step S12, dividing the cooling time into at least two heating supplementary time periods, and determining the air conditioning forecast load of each heating supplementary time period according to the load forecast data;

[0089] Sub-step S13, determining the total auxiliary heating amount according to the predicted air conditioning load in each heating period and the total re-injected heat amount;

[0090] Sub-step S14, allocating the amount of supplementary heat to each time period according to the total amount of supplementary heat and the preset supplementary heat threshold value of each supplementary heat period, to obtain the amount of supplementary heat to each supplementary heat period;

[0091] Sub-step S15, extracting the auxiliary heating amount corresponding to the current period from the auxiliary heating amount of each heating period;

[0092] Sub-step S16, using the auxiliary heating amount corresponding to the current time period and combining it with the predicted air conditioning load of the current time period to perform a prediction, to obtain the predicted heating amount corresponding to the current time period.

[0093] Among them, the air-conditioning predicted load refers to the predicted air-conditioning load that needs to be generated; the total auxiliary heating heat refers to the total amount of heating heat that the auxiliary heating equipment needs to generate during the entire cooling time; the preset heating heat threshold of the heating period refers to the maximum heat threshold that can be stored under the working conditions of the heating period, which can be set according to the maximum heat exchange capacity of the soil. For example, the heat exchange capacity calculation formula HER=f(T1, T2, G) can be used to calculate the inlet water temperature T1 entering the equipment, the soil temperature T2 and the water flow rate G of the refrigerant medium to calculate the maximum heat exchange capacity of the cold source tower in the ground source heat pump in different heating periods, which is used as the preset heating heat threshold for each heating period; the auxiliary heating heat in the heating period refers to the heat that the auxiliary heating equipment needs to generate during the heating period.

[0094] Specifically, after obtaining the load forecast data, the embodiment of the present application can divide the cooling time of the air conditioner into two or more supplementary heating periods according to the changes in meteorological parameters throughout the year, and can determine the air conditioner forecast load of each supplementary heating period according to the load forecast data, so as to calculate according to the air conditioner forecast load and the total re-injected heat of each supplementary heating period, and determine the total amount of supplementary heat that the auxiliary heating equipment needs to generate during the entire cooling time as the total amount of auxiliary supplementary heat, so that the supplementary heat for each period can be allocated based on the total amount of auxiliary supplementary heat and the preset supplementary heat threshold of each supplementary heating period, so as to obtain the auxiliary supplementary heat for each supplementary heating period.

[0095] Optionally, the embodiment of the present application determines the total auxiliary heating heat according to the predicted air conditioner load of each heating supplement period and the total re-injected heat, which may specifically include: statistically analyzing the predicted air conditioner load of each heating supplement period to obtain the total air conditioner load; using the total re-injected heat and the total air conditioner load to calculate to obtain the total auxiliary heating heat. The total air conditioner load refers to the total load required for air conditioning refrigeration during the entire cooling time. For example, when the cooling time is divided into n heating supplement periods, the predicted air conditioner load required to be generated in each heating supplement stage can be recorded as Q1 to Qn respectively, and according to the calculation formula ∑Qn=Q1+Q2……+Qn, the total air conditioner load ∑Qn is determined by statistically analyzing the sum of Q1 to Qn; Q1 is the predicted air conditioner load for the first heating supplement period, Q2 is the predicted air conditioner load for the second heating supplement period…, and so on, Qn is the predicted air conditioner load for the nth heating supplement period, and n is an integer greater than 1.

[0096] After predicting the total amount of auxiliary heating required for the entire cooling time, the embodiment of the present application can allocate the amount of heating required for each period according to the total amount of auxiliary heating combined with the preset heating threshold of each heating period, so as to predict the amount of auxiliary heating required for the auxiliary heating device in each heating period. In some optional embodiments of the present application, the allocation of heating required for each period according to the total amount of auxiliary heating combined with the preset heating threshold of each heating period to obtain the amount of auxiliary heating required for each heating period can specifically include the following sub-steps:

[0097] Sub-step S21, determining a preset heating threshold for each heating period according to the meteorological detection parameters of each heating period and combining the heating capacity information of the ground source heat pump;

[0098] Sub-step S22, according to the preset supplementary heating quantity threshold value of each supplementary heating period, the total auxiliary supplementary heating quantity is distributed according to the preset supplementary heating distribution method, starting from the last supplementary heating period in each supplementary heating period, to obtain the supplementary heating quantity allocated to each supplementary heating period;

[0099] Sub-step S23, determining the supplementary heat amount corresponding to each supplementary heat period as the auxiliary supplementary heat amount of each supplementary heat period.

[0100] Among them, meteorological detection parameters may refer to detected meteorological parameters, such as outdoor dry-bulb temperature T3, outdoor wet-bulb temperature T4, etc. detected by sensors, but not limited to; the heating capacity information of the ground source heat pump may include various information for determining the heating capacity of auxiliary heating equipment such as source tower equipment in the ground source heat pump, such as the heating capacity information of the ground source heat pump may include the water inlet temperature T1 and the water flow rate G entering the equipment in the buried pipeline, so that the maximum heating energy for different heating periods can be determined based on the water inlet temperature T1, water flow rate G and meteorological detection parameters as the preset heating amount threshold for the heating period.

[0101] For example, when the meteorological detection parameters include the outdoor dry-bulb temperature T3 and the outdoor wet-bulb temperature T4 detected by the sensor, the water inlet temperature T1 and the water flow rate G entering the equipment in the buried pipeline can be obtained as the heating capacity information of the ground source heat pump, and the heating capacity coefficient Qt at different air temperatures is obtained by calculation based on the heating capacity relationship Qt=f(T3, T4, T1, G), using the outdoor dry-bulb temperature T3, the outdoor wet-bulb temperature T4, the water inlet temperature T1 and the water flow rate G entering the equipment. The heating capacity coefficient Qt can reflect the heating capacity of the auxiliary heating equipment in the ground source heat pump system at different air temperatures. Therefore, the maximum heating energy under different air temperatures can be determined according to the heating capacity coefficient Qt under different air temperatures, and then the maximum heating energy under different air temperatures can be determined for each heating period as the preset heating amount threshold for each heating period.

[0102] After determining the preset supplementary heating amount threshold for each supplementary heating time period, the total auxiliary supplementary heating heat can be distributed according to the preset supplementary heating distribution method based on the preset supplementary heating amount threshold for each supplementary heating time period, starting from the last supplementary heating time period in the various supplementary heating time periods, so as to distribute the supplementary heating amount corresponding to each supplementary heating time period, thereby obtaining the supplementary heating amount corresponding to each supplementary heating time period, so as to subsequently determine the heat required to be generated by the auxiliary heating equipment in each supplementary heating time period according to the supplementary heating amount corresponding to each supplementary heating time period, that is, predict the auxiliary supplementary heating amount for each supplementary heating time period according to the supplementary heating amount corresponding to each supplementary heating time period, such as directly determining the auxiliary supplementary heating amount for each supplementary heating time period according to the heat required to be generated by the auxiliary heating equipment in each supplementary heating time period.

[0103] Among them, the preset heat supplement allocation method refers to the energy allocation method pre-set for heat supplement, such as the preset heat supplement allocation method can be a method of allocating from the last heat supplement period and in sequence forward. For example, the total auxiliary heat supplement heat can be allocated from the last heat supplement period and in sequence forward, and the corresponding allocated heat supplement heat in each heat supplement period should be less than the heat threshold that can be generated by the maximum heat supplement capacity of auxiliary heating equipment such as ground source towers within this time, and a certain amount of heat supplement margin can be reserved in the last two heat supplement periods to prevent the overall system heat supplement from being insufficient due to insufficient heat supplement in the previous heat supplement period, so as to achieve stable system operation while ensuring accurate control of cold and heat balance, which can effectively reduce the operating costs of the system and improve the operating energy efficiency of the ground source heat pump system.

[0104] Optionally, the embodiment of the present application allocates the supplementary heat amount corresponding to each supplementary heating period according to the preset supplementary heat threshold of each supplementary heating period, using the total auxiliary supplementary heat amount according to the preset supplementary heat allocation method, starting from the last supplementary heating period of the various supplementary heating periods, and obtaining the supplementary heat amount allocated to each supplementary heating period. Specifically, it may include: during the allocation process, determining the currently allocated supplementary heating period, and determining the total heat to be allocated based on the allocated heat corresponding to the currently allocated supplementary heating period and the total auxiliary supplementary heat amount; using the total heat to be allocated, and allocating it in combination with the preset supplementary heat threshold of the currently allocated supplementary heating period, to obtain the initial allocated supplementary heat amount corresponding to the currently allocated supplementary heating period; when the currently allocated supplementary heating period belongs to the preset adjustment period, adjusting the initial allocated supplementary heat amount corresponding to the currently allocated supplementary heating period according to the adjustment coefficient corresponding to the adjustment period, to obtain the allocated supplementary heat amount corresponding to the currently allocated supplementary heating period.

[0105] Specifically, in the process of allocating supplementary heating time periods, the embodiments of the present application can determine the allocated heat corresponding to the currently allocated supplementary heating time period according to the currently allocated supplementary heating time period, so as to determine the total heat to be allocated based on the allocated heat and the total auxiliary supplementary heating heat, so that the total heat to be allocated can be used in combination with the preset supplementary heating heat threshold of the currently allocated supplementary heating time period for allocation, so as to obtain the initial allocated supplementary heating heat corresponding to the currently allocated supplementary heating time period, and it can be judged whether the currently allocated supplementary heating time period belongs to the preset adjustment period, so that when the currently allocated supplementary heating time period belongs to the preset adjustment period, the initial allocated supplementary heating heat corresponding to the currently allocated supplementary heating time period is adjusted according to the adjustment coefficient corresponding to the adjustment period, so as to obtain the allocated supplementary heating heat corresponding to the currently allocated supplementary heating time period; and when the currently allocated supplementary heating time period does not belong to the preset adjustment period, the initial allocated supplementary heating heat can be directly determined as the allocated supplementary heating heat corresponding to the currently allocated supplementary heating time period.

[0106] Among them, the preset adjustment period can be a heating period pre-set for adjusting absorption. For example, the last two heating periods in the cooling time can be set as adjustment periods, and the adjustment coefficients corresponding to the last two heating periods can be set to coefficients less than 1, so as to reserve a certain heating margin in the last two heating periods to prevent the overall heating shortage of the system caused by insufficient heating in the previous heating period. While achieving stable system operation, it ensures precise control of the cold and heat balance, which can effectively reduce the operating costs of the system and improve the operating energy efficiency of the ground source heat pump system.

[0107] In some optional embodiments of the present application, based on the preset supplementary heat threshold of each supplementary heating time period, the total auxiliary supplementary heat is allocated according to the preset supplementary heat allocation method, starting from the last supplementary heating time period in the various supplementary heating time periods, to obtain the supplementary heat allocated corresponding to each supplementary heating time period, which may specifically include: in the allocation process, determining the currently allocated supplementary heating time period, and determining the total heat to be allocated based on the allocated heat corresponding to the currently allocated supplementary heating time period and the total auxiliary supplementary heat; using the total heat to be allocated, combined with the preset supplementary heat threshold of the currently allocated supplementary heating time period for allocation, to obtain the initial allocated supplementary heat corresponding to the currently allocated supplementary heating time period; when the currently allocated supplementary heating time period does not belong to the preset adjustment period, determining the initial allocated supplementary heat as the supplementary heat allocated corresponding to the currently allocated supplementary heating time period.

[0108] In summary, in the above example of the present application, during the allocation process, by judging whether the currently allocated supplementary heating period belongs to the preset adjustment period, if the currently allocated supplementary heating period belongs to the preset adjustment period, the initial allocated supplementary heating amount corresponding to the currently allocated supplementary heating period is adjusted according to the adjustment coefficient corresponding to the adjustment period to obtain the supplementary heating amount corresponding to the currently allocated supplementary heating period; and if the currently allocated supplementary heating period does not belong to the preset adjustment period, the initial allocated supplementary heating amount is directly determined as the supplementary heating amount corresponding to the currently allocated supplementary heating period, so that the supplementary heating amount corresponding to each supplementary heating period can be determined.

[0109] In addition, in order to reduce the occurrence of excessive or insufficient recharge heat, in some optional embodiments of the present application, the correction coefficient calculated by the recharge in the previous heating season can be used to correct the total heat extracted from the soil by the system in the previous heating season, so as to determine the corrected heat as the total recharge heat of the ground source heat pump during the cooling time. Optionally, the embodiment of the present application determines the total recharge heat of the ground source heat pump during the cooling time based on the historical record information corresponding to the ground source heat pump, which can specifically include: extracting the soil extraction heat record information of the ground source heat pump from the historical record information; using the soil extraction heat record information to determine the total soil extraction heat of the ground source heat pump during the preset heating time; using the supplementary heat correction coefficient of the ground source heat pump to correct the total soil extraction heat to obtain the total recharge heat of the ground source heat pump during the cooling time. Among them, the soil heat extraction record information of the ground source heat pump includes various information recorded for the ground source heat pump to extract heat from the soil, such as the total heat extracted from the soil by the ground source heat pump system in the previous heating season, which is used as the total heat that needs to be reinjected into the soil in the cooling season; the preset heating time may refer to the pre-set heating time, such as the time period set for heating throughout the year; the total soil heat extracted by the ground source heat pump within the preset heating time refers to the heat that the ground source heat pump needs to extract from the soil within the preset heating time.

[0110] As an example of the present application, take the heat source tower as an auxiliary heating device in the ground source heat pump system as an example. Figure 2 As shown, heat can be injected into the soil through the heat source tower. When the ground source heat pump system is initially operated, the heat supplement load calculation for each period can be performed through the load prediction module to calculate the heat supplement amount of the heat source tower for each period, thereby determining the amount of heat supplement required by the heat source tower during the period when the central air conditioning control system is working, and then sending the central air conditioning control system to the central air conditioning control system of the ground source heat pump system, and controlling the heat source tower to complete the corresponding heat supplement within the specified period through the central air conditioning control system.

[0111] Specifically, if Figure 3 As shown, the total heat extracted from the soil by the system in the previous heating season is first read as the total heat Qc0 extracted from the soil by the ground source heat pump during the preset heating time. Then, according to the heat supplement correction calculation formula Qc=Qc0*k, the total heat Qc0 extracted from the soil is multiplied by the correction coefficient k calculated by the reinjection in the previous heating season for correction. The total heat Qc0 extracted from the soil is corrected by the heat supplement correction coefficient k of the ground source heat pump to obtain the total reinjection heat Qc of the ground source heat pump during the cooling time.

[0112] In addition, the example of this application can read the annual building load forecast data to divide the overall cooling season into multiple heating periods. For example, the overall cooling season can be divided into 5 to 10 different heating periods according to different summer temperatures. If the heating period is too short, it is easily affected by weather factors; if the heating period is too long, the system regulation ability is limited and the regulation flexibility is low. Therefore, in some optional methods of this application, the duration of each heating period can be set according to the system stability requirements, such as a heating period of not less than one week and not more than one month.

[0113] In a specific implementation, the heat supplement capacity coefficient of the heat source tower equipment can be read, and this coefficient reflects the heating capacity of the heat source tower under different air temperatures. Based on the heat supplement capacity coefficient of the heat source tower equipment, the cooling capacity of the heat source tower under different conditions can be calculated according to the heat supplement capacity relationship Qt=f(T3, T4, T1, G). By reading the average meteorological parameters of different time periods, the maximum heat supplement energy in each heat supplement period can be determined, which is recorded as Qt1 to Qtn, wherein Qt1 is the maximum heat supplement energy in the first heat supplement period, and Qtn is the maximum heat supplement energy in the nth heat supplement period. The air-conditioning predicted load of each heat supplement period can be determined according to the annual building load forecast data, so that the total air-conditioning load ∑Qn required for cooling during the entire cooling time can be determined according to the air-conditioning predicted load of each heat supplement period.

[0114] After determining the total recharge heat Qc required by the ground source heat pump during the cooling time and the total air-conditioning load ∑Qn required for cooling, the total heat required for heating by the heat source tower can be calculated by the total recharge heat Qc and the total air-conditioning load ∑Qn required for cooling, as the total auxiliary heating heat Qz required for the entire cooling time, such as Qz=Qc-∑Qn. Subsequently, the total heat required for heating by the heat source tower can be allocated to each heating time period in a sequential manner, with reservation at the front and back ends. That is, the total auxiliary heating heat Qz is allocated from the last heating time period forward in sequence, wherein the amount of heating allocated in each heating time period should be less than the maximum heating capacity of the ground source tower during that time, and a certain amount of heating margin can be reserved in the last two heating times to prevent insufficient heating of the system as a whole due to insufficient heating in the previous heating time period.

[0115] For example, in the case where the cooling time is divided into n heat replenishment periods, according to the capacity calculation formula, the initial heat source tower heat replenishment Q0tn for the nth heat replenishment period can be obtained by subtracting the predicted air-conditioning load Qn for the nth heat replenishment period from the preset heat replenishment threshold HERn for the nth heat replenishment period, that is, Q0tn = HERn - Qn. Then, compare the calculated initial heat source tower heat replenishment Q0tn with the maximum heat replenishment Qnmax corresponding to the maximum heat replenishment capacity for this heat replenishment period to determine whether the calculated initial heat source tower heat replenishment Q0tn is less than the maximum heat replenishment Qnmax. If the initial heat source tower heat replenishment Q0tn is not less than the maximum heat replenishment Qnmax, then set the maximum heat replenishment Qnmax as the heat source tower heat replenishment Qrtn for the nth heat replenishment period, that is, Qrtn = Qnmax. If the initial heat source tower heat replenishment Q0tn is less than the maximum heat replenishment Qnmax, that is, Q0tn < Qnmax, then set the initial heat source tower heat replenishment Q0tn as the heat source tower heat replenishment Qrt for the nth heat replenishment period, that is, Qrtn = Q0tn. Subsequently, determine whether the current heat replenishment period is the last heat replenishment period. If the current heat replenishment period is the last heat replenishment period, then multiply the heat source tower heat replenishment Qrtn for this heat replenishment period by the corresponding adjustment coefficient 0.7 for the last heat replenishment period to adjust the heat source tower heat replenishment Qrtn using the adjustment coefficient 0.7, and determine the adjusted heat source tower heat replenishment as the auxiliary heat replenishment Qtn for this heat replenishment period, that is, Qtn = 0.7 * Qrtn. If the current heat replenishment period is not the last heat replenishment period, then determine whether the current heat replenishment period is the penultimate heat replenishment period. If the current heat replenishment period is the penultimate heat replenishment period, then multiply the heat source tower heat replenishment Qrtn for this heat replenishment period by the corresponding adjustment coefficient 0.8 for the penultimate heat replenishment period to adjust the heat source tower heat replenishment for the penultimate heat replenishment period using the adjustment coefficient 0.8, and determine the adjusted heat source tower heat replenishment Qrtn as the auxiliary heat replenishment for the penultimate heat replenishment period, that is, Qtn = 0.8*Qrtn; if the current supplementary heating period is not the second to last supplementary heating period, the heat source tower supplementary heating amount Qrtn of the supplementary heating period is determined as the auxiliary supplementary heating amount Qtn of the supplementary heating period, that is, Qtn=Qrtn, and then the sum of the currently allocated auxiliary supplementary heating amounts ∑Qtn can be counted as the allocated heat corresponding to the currently allocated supplementary heating period, and it can be determined whether the allocated heat is greater than the total auxiliary supplementary heating amount Qz required for the entire cooling time, that is, whether the sum of the currently allocated auxiliary supplementary heating amounts ∑Qtn is greater than the total auxiliary supplementary heating amount Qz required for the entire cooling time. The total auxiliary heating heat Qz is used to determine whether all the required heating heat is currently allocated to each heating period; if the allocated heat is greater than the total auxiliary heating heat Qz required for the entire cooling time, that is, ∑Qtn>Qz, it proves that all the required heating heat has been allocated to each heating period, and the auxiliary heating heat of the unallocated heating time period can be set to 0; if the allocated heat is not greater than the total auxiliary heating heat Qz required for the entire cooling time, that is, when the condition ∑Qtn>Qz does not hold, it means that all the required heating heat has not been allocated and needs to be continued. The auxiliary heating amount Qtn of the (n-1) heating period is determined based on the heat source tower heating amount of the (n-1) heating period, and so on and so forth until the total auxiliary heating amount Qz required for the entire cooling time is allocated. Then, the auxiliary heating amount corresponding to each heating period can be used according to the calculation formula, combined with the predicted load of each heating air conditioner, to obtain the predicted heating amount corresponding to each heating period. For example, the calculation formula can be used for the nth heating period. During the heating period, the auxiliary heating amount Qtn corresponding to the nth heating period is used in combination with the predicted air conditioning load Qn of the nth heating period to predict the predicted heating amount Qdn corresponding to the nth heating period, which is used as the heat to be injected back into the buried pipe during the nth heating period, so that the heating load can be corrected based on the predicted heating amount and the data collection information corresponding to the ground source heat pump, and the amount of heat to be supplemented by the ground source heat pump in the current period can be obtained. Then, the ground source heat pump can be controlled to perform heating in the current period based on the amount of heat to be supplemented.

[0116] In some optional embodiments of the present application, after each heating time period, the soil heat supplement that has occurred can be counted to calculate the amount of heat that is over- or under-supplied in the time period, and the difference can be added to the next heating time period to prevent the occurrence of insufficient or excessive quarterly heating supplement caused by cumulative heating supplement errors. Optionally, the present application embodiment performs heating supplement load correction based on the predicted heating supplement amount and the data collection information corresponding to the ground source heat pump to obtain the amount of heat to be supplemented by the ground source heat pump in the current time period, which can specifically include the following sub-steps:

[0117] Sub-step S31, extracting heat information of the ground pipe heat exchanger from the data collection information;

[0118] Sub-step S32, using the heat information of the ground pipe heat exchanger to determine the actual heat supplementation amount in the target historical period and the heat supplementation amount in the current period;

[0119] Sub-step S33, using the actual heating supplement amount and the total heating supplement amount predicted corresponding to the target historical period to determine the historical heating supplement difference;

[0120] Sub-step S33, performing heat supplement load correction based on the difference between the supplemented heat and the predicted supplemented heat in combination with the historical supplemented heat difference, to obtain the heat to be supplemented by the ground source heat pump in the current period.

[0121] Among them, the heat information of the buried pipe heat exchanger includes heat information related to the buried pipe heat exchanger, such as information recorded by the buried pipe heat exchanger heat meter. The information recorded by the buried pipe heat exchanger heat meter can be used to determine the amount of heat supplement input to the buried pipe heat exchanger in the current heating period and the amount of heat supplement input to the buried pipe heat exchanger in the previous heating period. Therefore, the amount of heat supplement input to the buried pipe heat exchanger in the current heating period can be used as the amount of heat supplement already added in the current period, and the actual amount of heat supplement in the target historical period can be determined based on the amount of heat supplement input to the buried pipe heat exchanger in the previous heating period. The target historical period is a period that has already been heated. For example, the previous heating period of the current period can be used as the target historical period, so that the heat supplement difference calculated in the previous heating time period can be used to perform heat supplement load correction later, thereby effectively preventing the occurrence of insufficient or excessive quarterly heating supplement caused by cumulative heating supplement errors.

[0122] For example, Figure 4 As shown, when the supplementary heating load correction starts, it can be determined whether the current time enters the next time period. When the time transitions from the current supplementary heating time period to another supplementary heating time period, the system reads the heat meter of the buried heat exchanger, and the actual supplementary heating amount input into the buried heat exchanger in the current time period can be counted. The actual supplementary heating amount can be compared with the predicted supplementary heating amount corresponding to the current time period to determine the supplementary heating difference value △Qd corresponding to the current time period, so as to use the supplementary heating difference value △Qd corresponding to the current time period to perform supplementary heating load correction on the heat to be supplemented in the next supplementary heating time period.

[0123] Specifically, according to the heat compensation load correction formula Qi = Qd(n + 1)+△Qd + △Q, the heat compensation difference value △Qd corresponding to the current time period can be included in the heat quantity Qi required in the next heat compensation period. △Q is the heat compensation difference value in the next heat compensation period. For example, the heat quantity Qi required in the next heat compensation period can be compared with the maximum heat compensation quantity Qimax corresponding to the maximum heat source tower heat compensation capacity in the next heat compensation period to determine whether the heat quantity Qi required in the next heat compensation period is less than the maximum heat compensation quantity Qimax. If the heat quantity Qi required in the next heat compensation period is less than the maximum heat compensation quantity Qimax, that is, when Qi < Qimax, the heat quantity Qi required in the next heat compensation period can be directly determined as the heat quantity to be supplemented in the next heat compensation period, so that heat compensation can be carried out according to the heat quantity to be supplemented in the next heat compensation period subsequently. If the heat quantity Qi in the next heat compensation period is not less than the maximum heat compensation quantity Qimax, the maximum heat compensation quantity Qimax can be subtracted from the heat quantity Qi in the next heat compensation period to obtain the heat compensation difference value △Q in the next heat compensation period, and the maximum heat compensation quantity Qimax can be determined as the heat quantity to be supplemented in the next heat compensation period, so that heat compensation can be carried out according to the heat quantity to be supplemented in the next heat compensation period subsequently, realizing the heat compensation load correction for each period, ensuring the precise control of the cold and heat balance while achieving the stable operation of the system, effectively reducing the operation cost of the system, and improving the operation energy efficiency of the heat pump system.

[0124] In some alternative embodiments of the present application, after the final heat compensation is completed, the average soil temperature can be read to compare the average soil temperature with the designed soil temperature, so that in the case of a decrease or increase in the soil temperature, that is, too much or too little heat is recharged into the soil during this cooling season, the corresponding correction value can be calculated to correct the heat compensation quantity in the next heat compensation quarter, thereby realizing the precise control of the annual cold and heat balance of the ground source, and solving the problems such as large deviation in heat storage capacity and inflexible equipment adjustment caused by weather changes and long-term operation of the system in the existing related technologies.

[0125] Optionally, the embodiment of the present application controls the ground source heat pump to supplement heat in the current period according to the heat to be supplemented, which may specifically include: determining the current control time; when the current control time reaches the specific ground temperature correction time of the current period, judging whether the air conditioning and refrigeration system of the ground source heat pump stops running; when the air conditioning and refrigeration system stops running, shutting down all auxiliary heating equipment in the ground source heat pump and controlling the operation of the ground pipe heat exchanger in the ground source heat pump; when the number of running ground pipe heat exchangers reaches the preset number of running, determining the current soil temperature according to the monitored ground pipe outlet water temperature; comparing the current soil temperature with the preset soil temperature threshold to obtain the ground temperature comparison result; and updating the heat supplement correction coefficient of the ground source heat pump according to the ground temperature comparison result. Among them, the current control time refers to the current control time; the specific ground temperature correction time refers to the specific correction time pre-set for the ground temperature, such as for each heat supplement period, the last heat supplement time of the heat supplement period can be set to the specific ground temperature correction time of the heat supplement period, and then the last heat supplement time can be used to realize the ground temperature judgment correction in the last time period.

[0126] As an example of the present application, the last month of the supplementary heating period can be set as a specific ground temperature correction time, so as to use the last month to implement ground temperature judgment correction. Specifically, when the ground temperature judgment correction starts in the last month, Figure 5 As shown, it is possible to determine whether the current control time has entered the last heating supplement period, and when the current control time has entered the last heating supplement period, read the soil design initial temperature T0 as the preset soil temperature threshold, and then determine whether cooling is currently being performed, so as to determine whether the air-conditioning and refrigeration system of the ground source heat pump has stopped running by determining whether cooling is currently being performed; if cooling is not currently being performed, that is, when the air-conditioning and refrigeration system has stopped running, it is possible to determine whether the heat source tower needs to be shut down by determining whether there is currently heat supplement from the heat source tower; when there is currently heat supplement from the heat source tower, all heat source towers can be shut down, so as to control the operation of the buried pipe heat exchanger in the ground source heat pump while shutting down all auxiliary heating equipment in the ground source heat pump, so that the number of running buried pipe heat exchangers reaches the preset number of running.

[0127] Among them, the preset operating number can be set to more than half of the total number of heat exchangers, such as 50% of the total number of heat exchangers, so that after entering the last heating time period when the air-conditioning refrigeration system is not running, all heat source towers are turned off, and only more than 50% of the buried pipe heat exchanger circulation pumps are operated to ensure a certain amount of circulation flow and maintain heat exchange stability.

[0128] Specifically, when the number of operating times of the buried pipe heat exchanger reaches a preset number of operating times, the current soil temperature can be determined based on the monitored buried pipe water outlet temperature, such as by judging whether the currently detected buried pipe water outlet temperature remains unchanged for 10 consecutive minutes (min), such as when the temperature fluctuation is between ±0.1°C, it is considered valid, and when the currently detected buried pipe water outlet temperature remains unchanged for 10 consecutive minutes, it is considered that the water temperature is consistent with the soil temperature, so that the current monitored buried pipe water outlet temperature can be used to determine the current soil temperature Tt, and the current soil temperature Tt can be compared with the design soil temperature T0, so as to compare the current soil temperature with the preset soil temperature threshold to obtain a ground temperature comparison result, so that the heat supplement correction coefficient of the ground source heat pump can be updated based on the ground temperature comparison result, such as by judging whether the current soil temperature Tt is greater than the value between the design soil temperature T0 and the preset excess heat supplement △T The sum of the values ​​can be used to determine whether there is excessive heating supplement; if the current soil temperature Tt is greater than the sum of the design soil temperature T0 and the preset excessive heating amount △T, that is, when Tt>Tt0+△T, it indicates excessive heating supplement. In the next quarter, the total heating amount can be multiplied by a certain proportional coefficient K, such as the value of the proportional coefficient K can be set to 0.9, that is, K=0.9, to reduce the corresponding heating amount; if the current soil temperature Tt is not greater than the sum of the design soil temperature T0 and the preset excessive heating amount △T, it can be determined whether there is a problem of insufficient heating supplement by whether the current soil temperature Tt is less than the difference between the design soil temperature T0 and the preset excessive heating amount △T. When the current soil temperature Tt is less than the difference between the design soil temperature T0 and the preset excessive heating amount △T, the value of the proportional coefficient K is set to 1.1, that is, K=1.1. In the next quarter, the proportional coefficient K is multiplied by the total heating amount to increase the corresponding heating amount. When the current soil temperature Tt is not greater than the sum of the design soil temperature T0 and the preset excess heat compensation △T and is not less than the difference between the design soil temperature T0 and the preset excess heat compensation △T, the value of the proportional coefficient K is set to 1, so that in the next quarter, the proportional coefficient K can be used to realize accurate calculation of the cold and hot loads to ensure the heat intake of the heat pump unit, greatly improve the operating efficiency of the heat pump unit, improve resource utilization efficiency, eliminate cold and hot accumulation and cold and hot imbalance in the buried pipe heat exchanger, effectively restore the soil temperature around the buried pipe, and protect the soil ecological environment.

[0129] Among them, △T can represent excessive heat supplementation, which can generally be 0.5~1℃, or greater than 1℃. It can be changed according to the heating time, but △T should be less than 2 as much as possible to prevent excessive heating.

[0130] It should be noted that, for the purpose of simple description, the method embodiments are expressed as a series of action combinations, but those skilled in the art should be aware that the embodiments of the present application are not limited to the described order of actions, because according to the embodiments of the present application, certain steps may be performed in other orders or simultaneously.

[0145] Optionally, the total auxiliary heating heat is allocated according to a preset heating allocation method based on a preset heating allocation threshold value of each heating allocation period, starting from the last heating allocation period in each heating allocation period, to obtain the heating amount allocated corresponding to each heating allocation period, including:
