Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to an air conditioning control method and apparatus, air conditioning equipment and computer-readable storage medium. Background Technology

[0002] As living standards improve, people's demand for intelligent control of air conditioners is also increasing. Currently, air conditioners support scheduled start-up and scheduled shutdown functions, with scheduled start-up including two different operating modes: pre-cooling and pre-heating.

[0003] However, current air conditioner's scheduled start / stop functions typically turn the air conditioner on / off automatically at the scheduled time. When using functions like pre-cooling, pre-heating, or scheduled shutdown, users cannot determine the desired duration. This can easily lead to energy waste due to the air conditioner being on for too long or off for too short a time, or failure to reach a comfortable temperature due to either too short an on or too long off time, significantly impacting the user experience. Summary of the Invention

[0034] Further, the step of obtaining the target building envelope heat storage characteristic data of the space where the air conditioning equipment is located from the initial building envelope heat storage characteristic data of the space where the air conditioning equipment is located includes:

[0035] From the initial thermal storage characteristic data of the building envelope where the air conditioning equipment is located, target thermal storage characteristic data of the building envelope that meet the requirements of the indoor building envelope thermal storage capacity are selected.

[0037] Obtain the target internal heat source characteristic data of the space where the air conditioning equipment is located;

[0038] Based on the target internal heat source characteristic data, the heat capacity of the building envelope, the air heat capacity, and the heat transfer characteristic data and ventilation characteristic data corresponding to the building envelope of the space where the air conditioning equipment is located, the real-time heat transfer load, real-time ventilation heat load, and real-time heat storage / release of the building envelope of the space where the air conditioning equipment is located, as well as the real-time heat storage / release of the indoor air in the space where the air conditioning equipment is located, are calculated.

[0069] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0070] The scheduled start-up (including pre-cooling and pre-heating) or scheduled shutdown (i.e., early shutdown) of air conditioners are based on the entire air conditioning system. However, air conditioning serves a building space. Due to differences in the location, orientation, heat sources, and service hours (such as commuting times) of a building space, the required scheduled start-up or early shutdown times vary. Furthermore, the biggest question people have when using pre-cooling, pre-heating, and early shutdown functions is how to determine the required time length. Therefore, a personalized control method for pre-cooling, pre-heating, and early shutdown based on the specific needs of a building space is needed, automatically setting the start-up and shutdown times. Based on this, the air conditioning control method and device, air conditioning equipment, and computer-readable storage medium provided in this invention can solve the problem of determining the optimal pre-cooling, pre-heating, and early shutdown times for different spaces within a building.

[0071] To facilitate understanding of this embodiment, a detailed description of an air conditioning control method disclosed in this embodiment of the invention will be provided first.

[0072] This invention provides an air conditioning control method, which can be executed by an air conditioning device. See also... Figure 1 The diagram shows a flow chart of an air conditioning control method, which mainly includes the following steps S102 to S106:

[0073] Step S102: Receive a reservation control instruction for the air conditioning equipment; wherein the reservation control instruction includes at least the reservation time and reservation temperature value.

[0074] The aforementioned scheduled time is set by the user. The aforementioned scheduled control command may also include a task type, which may include scheduled power-on or scheduled power-off. Scheduled power-on may be for pre-cooling or pre-heating. When the task type is scheduled power-on, the scheduled temperature value can be user-set or a default setting; when the task type is scheduled power-off, the scheduled temperature value may be the upper limit of human comfort temperature. This upper limit of comfort temperature can be calculated based on the operating status of the air conditioning equipment before scheduled power-off.

[0075] Optionally, if the air conditioner is in cooling mode before the scheduled shutdown, the upper limit temperature value for comfort can be calculated with a relative humidity of RH = 50% and a PMV (Predicted Mean Vote) of +1; if the air conditioner is in heating mode before the scheduled shutdown, the upper limit temperature value for comfort can be calculated with a relative humidity of RH = 50% and a PMV of -1. PMV is an evaluation index used to reflect the human body's thermal response (feeling of hot or cold), representing the feeling of hot or cold experienced by most people in the same environment. PMV corresponds to seven levels of sensation: cold (-3), cool (-2), slightly cool (-1), neutral (0), slightly warm (1), warm (2), and hot (3).

[0076] Step S104: When the remaining set time before the reservation time is determined, the target time required for the space where the air conditioning equipment is located to reach the reservation temperature value is determined based on the real-time environmental characteristic data of the space where the air conditioning equipment is located and the heat transfer characteristic data of the space where the air conditioning equipment is located.

[0077] The set duration can be set according to the actual situation, and this embodiment does not limit it. Optionally, the set duration can correspond to the task type. When the task type is different, the set duration can be the same or different. For example, when the task type is pre-cooling or pre-heating, the set duration can be 5 minutes, and when the task type is scheduled shutdown, the set duration is 10 minutes.

[0078] The space where the air conditioning unit is located is determined based on the spatial position of the indoor unit within the building; that is, the space where the air conditioning unit is located refers to the space where the indoor unit is situated. Real-time environmental characteristic data of the space where the air conditioning unit is located can be obtained when the remaining time before the scheduled time is determined, while heat transfer characteristic data of the space can be obtained in advance. The real-time environment of the space where the air conditioning unit is located affects the air temperature there, and heat also transfers through the space, thus affecting the air temperature. Therefore, the target duration is determined based on both the real-time environmental characteristic data and the heat transfer characteristic data of the space where the air conditioning unit is located.

[0079] Step S106: When the remaining target time before the reservation time is determined, control the air conditioning equipment to execute the reservation control command.

[0080] When the remaining target time before the scheduled time is determined, the operation of the air conditioning equipment can be controlled according to the task type. For example, if the scheduled time is 18:00:00, the task type is pre-cooling, and the target time is 30 seconds, then the indoor cooling unit of the air conditioning equipment will be turned on when there are 30 seconds left before 18:00:00 (i.e., 17:59:30).

[0081] The air conditioning control method provided in this invention determines the target time required for the space where the air conditioning equipment is located to reach the preset temperature value based on real-time environmental characteristic data and heat propagation characteristic data of the space where the air conditioning equipment is located. This fully considers the influence of heat propagation in the space where the air conditioning equipment is located under real-time environmental conditions, making the determined target time more accurate. Thus, the human body's comfort requirements for the environment can be met at the preset time, while reducing energy consumption and saving energy.

[0082] For ease of understanding, the embodiments of the present invention further refine the above-described air conditioning control method, see [link to relevant documentation]. Figure 2 The flowchart of another air conditioning control method is shown, which includes the following steps S202 to S210:

[0083] Step S202: Obtain heat transfer characteristic data of the space where the air conditioning equipment is located.

[0084] Considering that the enclosure structure of the space where the air conditioning equipment is located affects the air temperature of that space through heat transfer and ventilation, in some possible embodiments, heat transfer characteristic data and ventilation characteristic data corresponding to the enclosure structure of the space where the air conditioning equipment is located can be obtained. Based on these data, heat propagation characteristic data of the space where the air conditioning equipment is located can be obtained. The enclosure structure can be walls or other objects that enclose the space where the air conditioning equipment is located.

[0085] Step S204: Receive a reservation control instruction for the air conditioning equipment; wherein the reservation control instruction includes the reservation time, task type and reservation temperature value.

[0086] Step S206: When the remaining set time before the reservation time is determined, real-time environmental characteristic data of the space where the air conditioning equipment is located is obtained.

[0087] In some possible embodiments, real-time environmental data of the space where the air conditioning unit is located can be acquired, and based on this data, real-time environmental characteristic data of the space can be obtained. The real-time environmental data may include indoor air temperature, indoor relative humidity, outdoor air temperature, and outdoor relative humidity. The indoor air temperature and relative humidity can be detected by the indoor unit of the air conditioning unit, while the outdoor air temperature and relative humidity can be detected by the outdoor unit. The outdoor relative humidity may also be derived from local meteorological data. The real-time environmental data may further include meteorological parameters, such as whether it is raining and outdoor wind speed.

[0088] In one possible implementation, real-time environmental data can be used as real-time environmental feature data. In another possible implementation, real-time environmental data can be processed, and the processing result and real-time environmental data can be used as real-time environmental feature data; for example, based on indoor air temperature, indoor relative humidity, outdoor air temperature, and outdoor relative humidity, the enthalpy difference between indoor and outdoor air can be calculated, and the enthalpy difference between indoor and outdoor air and real-time environmental data can be used as real-time environmental feature data.

[0089] Step S208: Based on the real-time environmental characteristic data of the space where the air conditioning equipment is located and the heat transfer characteristic data of the space where the air conditioning equipment is located, determine the target time required for the space where the air conditioning equipment is located to reach the preset temperature value.

[0090] Step S210: When the remaining target time before the scheduled time is determined, control the operation of the air conditioning equipment according to the task type.

[0091] In this embodiment, heat propagation characteristic data of the space where the air conditioning equipment is located is acquired in advance. The heat propagation characteristic data may include heat transfer characteristic data and ventilation characteristic data corresponding to the enclosure structure of the space where the air conditioning equipment is located. When the remaining time before the scheduled time is determined, the real-time environmental characteristic data of the space where the air conditioning equipment is located is acquired. Based on the real-time environmental characteristic data and the heat propagation characteristic data of the space where the air conditioning equipment is located, the target time required for the space where the air conditioning equipment is located to reach the scheduled temperature value is determined. This takes into account the influence of the heat transfer and ventilation characteristics of the enclosure structure of the space where the air conditioning equipment is located under the real-time environmental conditions, making the determined target time more accurate. Thus, the human body's comfort requirements for the environment can be met at the scheduled time, while reducing energy consumption and saving energy.

[0092] When acquiring heat transfer characteristic data of the space where the air conditioning equipment is located, indoor units located in the same space can be grouped together (the same space means that there is no enclosure structure between indoor units and they can be connected). Heat transfer characteristic data are determined for the space where the indoor units in the same group as the current air conditioning equipment are located (the space where the air conditioning equipment is located).

[0093] For easier understanding of the indoor unit grouping, please refer to [link / reference]. Figure 3 The diagram shows a grouping of indoor units. The grouping result is as follows:

[0094] Area 1: #1;

[0095] Area 2: #2, #3;

[0096] Area 3: #4, #5;

[0097] Area 4: #6, #7, #8, #9, #10.

[0098] To facilitate understanding, the following section introduces various methods for obtaining heat transfer characteristic data of the space where air conditioning equipment is located.

[0099] Method 1:

[0100] 1.1 Obtain the heat transfer and ventilation characteristics data corresponding to the enclosure structure of the space where the air conditioning equipment is located.

[0101] In some possible embodiments, heat transfer characteristic data can be heat transfer coefficient values, and the heat transfer coefficient KA of the building envelope can be determined using a heat flux density meter. Ventilation characteristic data can be ventilation characteristic parameter values, where the ventilation characteristic parameter F (unit: m³) is... 3 The area ( / h) can be determined through on-site measurement. For example, if the space where the air conditioning unit is located has only one window with an area of ​​2m², then the area can be determined by on-site measurement. 2 If the wind speed is 1 m / s, then the ventilation characteristic parameter F of this space is 2 m. 3 / s; The ventilation characteristic parameter F can also be determined by the air volume of the fresh air unit or the design heat exchange rate (some fresh air units use air volume, while others use the design heat exchange rate). For example, F can be calculated by using the wind speed and the size of the heat dissipation vent (window area) in the relevant parameters of the design heat exchange rate.

[0102] In some other possible embodiments, considering that the heat transfer coefficient KA and ventilation characteristic parameter F of the building envelope have a functional relationship with the outdoor wind speed and whether it is raining: KA = f1 (rain or no rain, wind speed range), F = f2 (rain or no rain, wind speed range), based on this, the heat transfer coefficient KA and ventilation characteristic parameter F of the building envelope can be determined by big data identification and fitting of the building heat balance equation, based on the historical operating data of the old air conditioner or the trial operation data of the new air conditioner (the operating data obtained by the data collection system of the new air conditioner when it is running under specified conditions).

[0103] 1.2 The heat transfer characteristic data and ventilation characteristic data corresponding to the enclosure structure of the space where the air conditioning equipment is located are determined as the heat transfer characteristic data of the space where the air conditioning equipment is located.

[0104] This acquisition method mainly considers the heat transfer and ventilation effects of the building envelope where the air conditioning equipment is located.

[0105] Method 2:

[0106] 2.1 Obtain the heat transfer and ventilation characteristics data corresponding to the enclosure structure of the space where the air conditioning equipment is located.

[0107] 2.2. Based on the heat transfer and ventilation characteristics data of the enclosure structure of the space where the air conditioning equipment is located, determine the air heat capacity of the space where the air conditioning equipment is located.

[0108] Air heat capacity (unit: kJ / K) can be used to calculate the time required to reach a comfortable temperature based on the output of air conditioning equipment and external conditions, guiding optimized control of rapid cooling and heating. Air heat capacity can be determined based on building information, specifically the size of the indoor space and the operating range of the air conditioning equipment. For example, the length, width, and height of the space where the air conditioning equipment is located are determined based on its operating range, the corresponding air volume is calculated, and the heat storage capacity characteristic value (i.e., air heat capacity value) of the space where the air conditioning equipment is located is obtained by multiplying the air specific heat capacity by the air volume.

[0109] 2.3 The heat capacity of the air in the space where the air conditioning equipment is located, as well as the heat transfer characteristics and ventilation characteristics of the building envelope of the space where the air conditioning equipment is located, are determined as the heat transfer characteristic data of the space where the air conditioning equipment is located.

[0110] This acquisition method not only considers the heat transfer and ventilation effects of the building envelope where the air conditioning equipment is located, but also the heat storage / release effects of the air in the space where the air conditioning equipment is located.

[0111] Method 3:

[0112] 3.1 Obtain the heat transfer and ventilation characteristics data corresponding to the enclosure structure of the space where the air conditioning equipment is located.

[0113] 3.2. Based on the heat transfer and ventilation characteristics data of the enclosure structure of the space where the air conditioning equipment is located, determine the air heat capacity of the space where the air conditioning equipment is located.

[0114] 3.3 Determine the thermal capacity of the building envelope of the space where the air conditioning equipment is located.

[0115] The thermal capacity of the building envelope (unit: kJ / K) can be used to calculate how far in advance the temperature needs to be set for electricity demand response to meet peak shaving and comfort requirements. Taking the building envelope as a wall as an example, the heat storage capacity per unit volume of the wall and the total volume of the wall can be determined based on the building information. Multiplying these two values ​​yields the total heat storage capacity of the space where the air conditioning equipment is located (i.e., the thermal capacity of the building envelope).

[0116] 3.4 The heat capacity of the enclosure structure, the heat capacity of the air, and the heat transfer and ventilation characteristics of the enclosure structure of the space where the air conditioning equipment is located are determined as the heat transfer characteristic data of the space where the air conditioning equipment is located.

[0117] This acquisition method not only considers the heat transfer and ventilation effects of the building envelope where the air conditioning equipment is located, as well as the heat storage / release effects of the air in the space where the air conditioning equipment is located, but also the heat storage / release effects of the building envelope.

[0118] Method 4:

[0119] 4.1 Obtain the heat transfer and ventilation characteristics data corresponding to the enclosure structure of the space where the air conditioning equipment is located.

[0120] 4.2. Based on the heat transfer and ventilation characteristics data corresponding to the enclosure structure of the space where the air conditioning equipment is located, determine the air heat capacity of the space where the air conditioning equipment is located.

[0121] 4.3 Determine the heat capacity of the building envelope of the space where the air conditioning equipment is located.

[0122] 4.4. Based on the heat capacity of the building envelope, the air heat capacity, and the heat transfer and ventilation characteristics of the building envelope, the internal heat source characteristics of the space where the air conditioning equipment is located are determined.

[0123] 4.5 The heat source characteristics data of the space where the air conditioning equipment is located, the air heat capacity, and the heat transfer characteristics data and ventilation characteristics data corresponding to the enclosure structure of the space where the air conditioning equipment is located are determined as the heat transfer characteristic data of the space where the air conditioning equipment is located.

[0124] This acquisition method not only considers the heat transfer and ventilation effects of the building envelope where the air conditioning equipment is located, as well as the heat storage / release effects of the air in the space where the air conditioning equipment is located, but also the influence of indoor heat sources.

[0125] Furthermore, step 4.5 above can be modified as follows: The heat source characteristic data of the space where the air conditioning equipment is located, the heat capacity of the building envelope, the air heat capacity, and the heat transfer and ventilation characteristic data corresponding to the building envelope of the space where the air conditioning equipment is located are determined as the heat transfer characteristic data of the space where the air conditioning equipment is located. This comprehensively considers the heat transfer and ventilation effects of the building envelope of the space where the air conditioning equipment is located, the heat storage / release effects of the air and the heat storage / release effects of the building envelope, as well as the influence of indoor heat sources.

[0126] Considering the difficulty in testing the heat transfer coefficient and ventilation characteristics of the building envelope, these parameters can be determined using building feature identification methods. See [link to relevant documentation]. Figure 4 The flowchart shown is a schematic diagram of an air conditioning control method for obtaining the heat transfer coefficient and ventilation characteristic parameters of the building envelope of the space where the air conditioning equipment is located. The process of determining the heat transfer coefficient and ventilation characteristic parameters of the building envelope through building feature recognition is as follows:

[0127] Step S402: Obtain target heat transfer and ventilation characteristic data of the space where the air conditioning equipment is located from the initial heat transfer and ventilation characteristic data of the space where the air conditioning equipment is located; wherein, the target heat transfer and ventilation characteristic data includes whether it is raining and the outdoor wind speed value.

[0128] The initial heat transfer and ventilation characteristic data can be the raw dataset of the space where the air conditioning equipment is located. This raw dataset can include historical operating data of all air conditioning equipment within the space and local meteorological data. Historical operating data can include the air conditioning energy output (cooling capacity Q) of the indoor unit. c Or heat output Q h The data includes the indoor unit's operating status at different times (cooling, heating, off, or standby), the indoor air temperature detected by the indoor unit, the indoor relative humidity detected by the indoor unit, the outdoor air temperature detected by the outdoor unit, and the outdoor relative humidity detected by the outdoor unit. Local meteorological data may include whether it is raining, wind speed range, solar irradiance, and outdoor relative humidity. When historical operating data does not include outdoor relative humidity, the outdoor relative humidity value from local meteorological data can be used.

[0129] Target heat transfer and ventilation characteristic data that meet the identification requirements of the building envelope can be selected from the initial heat transfer and ventilation characteristic data of the space where the air conditioning equipment is located. These requirements include: cooling operation; an average temperature difference between indoor and outdoor air greater than a first preset temperature difference value; an hourly minimum temperature difference between indoor and outdoor air greater than a second preset temperature difference value; and outdoor air temperature fluctuations not exceeding a preset fluctuation threshold. The first preset temperature difference value, the second preset temperature difference value, and the preset fluctuation threshold can all be set according to actual needs and are not limited here.

[0130] For example, the requirements for identifying heat transfer and ventilation in the building envelope include: cooling operation; an average temperature difference between indoor and outdoor air greater than 3.5K, and a minimum hourly temperature difference greater than 3K, to ensure the temperature difference exceeds the sensor's accuracy; and an average outdoor air temperature fluctuation not exceeding 1.5K, to eliminate unstable data. Preferably, a test mode can be set to start all indoor units for cooling operation in the early morning or late evening (e.g., 4:00 am to 5:30 am), with the temperature set at least 3.5K lower than the outdoor air temperature, and a minimum hourly temperature difference greater than 3K.

[0131] After obtaining the target heat transfer and ventilation characteristic data, it is also necessary to determine whether the sample size of the target heat transfer and ventilation characteristic data has reached the preset number. Only when the preset number is reached will step S404 be executed to meet statistical requirements. The preset number can be set according to actual needs, for example, the preset number is 20.

[0132] Step S404: Group the target heat transfer and ventilation characteristic data according to the parameter combination consisting of whether it is raining and the outdoor wind speed range to obtain multiple grouped data.

[0133] For example, possible parameter combinations are {no rain, 0~0.5m / s}, {rain, 0~0.5m / s}, {no rain, 0.5~1m / s}, {rain, 0.5~1m / s}, etc.

[0134] Step S406: Based on the data of each group, determine the heat transfer coefficient value and air exchange characteristic parameter value corresponding to the corresponding parameter combination.

[0135] Based on the data from each group, the heat transfer coefficient and ventilation characteristic parameter values ​​corresponding to the respective parameter combinations can be obtained by fitting.

[0136] When solving for KA and F, the building heat transfer process is relatively steady-state, with stable air conditioning capacity output, outdoor air temperature, and indoor air temperature. Based on this, for each group of data, the corresponding heat transfer coefficient and ventilation characteristic parameters can be obtained by fitting the following formula (a simplified heat balance equation after removing complex loads):

[0137]

[0138] Among them, Q cool Δh represents the air conditioning capacity output (the cooling capacity output by the air conditioner), F represents the ventilation characteristic parameter of the building envelope, KA represents the heat transfer coefficient of the building envelope, Δh represents the enthalpy difference between indoor and outdoor air (i.e., the difference between the enthalpy values ​​of indoor and outdoor air), and ΔT represents the temperature difference between indoor and outdoor air.

[0139] Δh is equal to the difference between the indoor air enthalpy and the outdoor air enthalpy. The air enthalpy h can be calculated using the following formula:

[0140] h = 1.005T + (2500 + 1.86T)d

[0141]

[0142]

[0143] Where T is the air temperature (K); d is the moisture content (g / kg); P represents relative humidity (%); P represents atmospheric pressure. w It is the partial pressure of water vapor (Pa).

[0144] This building feature recognition method makes extensive use of the sensors built into the air conditioning equipment, reducing equipment investment. Compared with building feature recognition methods that do not perform data screening, this data-screening method determines the heat transfer coefficient and ventilation characteristics of the building envelope of the space where the air conditioning equipment is located more accurately.

[0145] Considering situations where building information is unavailable, the air heat capacity of the space where the air conditioning equipment is located can be determined using building feature identification methods. See also Figure 5The diagram illustrates a process for determining the air heat capacity of the space where the air conditioning equipment is located in an air conditioning control method. The process of determining the air heat capacity using building feature recognition methods is as follows:

[0146] Step S502: Obtain target air heat storage characteristic data of the space where the air conditioning equipment is located from the initial air heat storage characteristic data of the space where the air conditioning equipment is located.

[0147] The initial air heat storage characteristic data can be the original dataset of the space where the air conditioning equipment is located. The original dataset can include the historical operating data of all air conditioning equipment in the space where the air conditioning equipment is located and local meteorological data.

[0148] Target air heat storage characteristic data that meets the indoor air heat storage capacity requirements can be filtered from the initial air heat storage characteristic data of the space where the air conditioning equipment is located. These requirements include: the indoor air conditioning unit being turned off; the indoor air temperature difference between the moment the unit is turned off and the moment the temperature stabilizes being greater than a third preset temperature difference value; solar irradiance being lower than a preset irradiance value; indoor heat source intensity being less than a preset percentage during normal use; and the indoor air temperature difference after final stabilization being less than a fourth preset temperature difference value. The third preset temperature difference value, preset irradiance value, preset percentage, and fourth preset temperature difference value can all be set according to actual needs and are not limited here.

[0149] For example, indoor air heat storage capacity requirements include: the indoor unit is turned off, and the temperature difference between the initial moment (when the unit is turned off) and the final stable moment is greater than 2°C; the solar irradiance in the climate parameters is less than 0.5 W / m². 2 The indoor heat source intensity is less than 5% of that during normal use; the temperature difference after the indoor air finally stabilizes is less than 0.5℃. Preferably, a test mode can be set to start all indoor units in the early morning (e.g., 4:00 am to 5:30 am), with the temperature set more than 4℃ lower than the outdoor air temperature (cooling) / more than 4℃ higher than the outdoor air temperature (heating), running for 1 hour, then turning off all indoor units until the indoor air temperature fluctuation is less than 0.5℃ within 20 minutes.

[0150] After obtaining the target air heat storage characteristic data, it is also necessary to determine whether the sample size of the target air heat storage characteristic data has reached the preset number. Only when the preset number is reached will step S504 be executed to meet statistical requirements. The preset number can be set according to actual needs, for example, the preset number is 20.

[0151] Step S504: Based on the target air heat storage characteristic data of the space where the air conditioning equipment is located, as well as the heat transfer characteristic data and ventilation characteristic data corresponding to the building envelope, determine the air heat capacity of the space where the air conditioning equipment is located.

[0152] The expression for the change of indoor air temperature T with time τ (empirical fitting formula) is as follows, where T0 represents the initial temperature, Δh represents the enthalpy difference between indoor and outdoor air, cm represents the air heat capacity, c represents the air specific heat capacity, m represents the indoor air mass, and ε represents a constant:

[0153]

[0154] The general fitting formula for the change of indoor air temperature T with time τ is as follows:

[0155] T = ae (-bτ+c) (2)

[0156] Based on the indoor air temperature values ​​at different times in the target air heat storage characteristic data, the parameter b can be obtained by screening the goodness of fit of equation (2). The fitting method can be the least squares method or a fitting method based on neural networks, etc. The accuracy reaches more than 90%, and meets the stability test requirements (the total proportion of the identification parameter error deviation of 10% reaches more than 85%).

[0157] Combining equations (1) and (2) above, we can obtain:

[0158]

[0159] Based on this, step S504 above can be implemented through the following process:

[0160] First, based on the indoor air temperature values ​​at different times in the target air heat storage characteristic data, the parameter b in the following expression for the change of indoor air temperature T with time τ is fitted:

[0161] T = ae (-bτ+c) ;

[0162] Then, determine the air heat capacity (cm²) of the space where the air conditioning unit is located using the following formula:

[0163]

[0164] Where KA represents the heat transfer coefficient of the building envelope, F represents the ventilation characteristic parameter of the building envelope, and Δh represents the enthalpy difference between indoor and outdoor air.

[0165] This building feature recognition method makes extensive use of the sensors built into the air conditioning equipment, reducing equipment investment. Compared with building feature recognition methods that do not perform data screening, this method, which does perform data screening, determines the air heat capacity of the space where the air conditioning equipment is located more accurately.

[0166] Considering situations where building information is unavailable, the thermal capacity of the building envelope where the air conditioning equipment is located can be determined using building feature recognition methods. See below for reference. Figure 6 The process of determining the heat capacity of the building envelope of the space where the air conditioning equipment is located is described below:

[0167] Step S602: Obtain the target building envelope heat storage characteristic data of the space where the air conditioning equipment is located from the initial building envelope heat storage characteristic data of the space where the air conditioning equipment is located.

[0168] The initial building envelope heat storage characteristic data can be the raw dataset of the space where the air conditioning equipment is located. This raw dataset may include historical operating data of all air conditioning equipment within the space and local meteorological data. Historical operating data may include the air conditioning energy output (cooling capacity Q) of the indoor units. c Or heat output Q h The data includes: the indoor unit's operating status at different times (cooling, heating, off, or standby), the indoor air temperature detected by the indoor unit, the indoor relative humidity detected by the indoor unit, the outdoor air temperature detected by the outdoor unit, the outdoor relative humidity detected by the outdoor unit, and the building envelope surface temperature. The building envelope surface temperature can be the wall temperature. Local meteorological data may include whether it is raining, wind speed range, solar irradiance, and outdoor relative humidity. When historical operating data does not include outdoor relative humidity, the outdoor relative humidity value from local meteorological data can be used.

[0169] Target thermal storage characteristics that meet the indoor thermal storage capacity requirements can be selected from the initial thermal storage characteristic data of the space where the air conditioning unit is located. These requirements include: the difference between the set temperature value when the indoor unit is turned on and the surface temperature of the building envelope before the unit is turned on is greater than a fifth preset temperature difference value; the difference between the surface temperature of the building envelope at the moment the indoor unit is turned on and at the moment the temperature stabilizes is greater than a sixth preset temperature difference value; solar irradiance is lower than a preset irradiance value; indoor heat source intensity is less than a preset percentage for normal use; and the final temperature difference after the indoor air stabilizes is less than a fourth preset temperature difference value. The fifth, sixth, preset temperature difference values, preset irradiance, preset percentage, and fourth preset temperature difference value can all be set according to actual needs and are not limited here.

[0170] For example, the required heat storage capacity of the indoor building envelope includes: when the indoor unit is turned on, the set temperature is at least 5°C higher or lower than the wall temperature before the indoor unit is turned on; after a preset time, the temperature difference between the wall temperature before the indoor unit is turned on and the wall temperature after they have stabilized is at least 3°C; and the solar irradiance in the climate parameters is less than 0.5 W / m². 2The indoor heat source intensity is less than 5% of that during normal use; the temperature difference after the indoor air finally stabilizes is less than 0.5℃. Preferably, a test mode can be set to start all indoor units in the early morning (4:00 am to 5:30 am), with the temperature set at more than 55℃ lower than the wall temperature before the indoor units are turned on (cooling) / the temperature set at more than 55℃ higher than the wall temperature before the indoor units are turned on (heating), and run for a preset time of 3 hours until the temperature fluctuation of the indoor air temperature and the wall temperature within 20 minutes is less than 0.5℃ (stability judgment condition), and the wall temperature after stabilization is more than 3℃ lower than the wall temperature before the units are turned on.

[0171] After obtaining the heat storage characteristic data of the target building envelope, it is also necessary to determine whether the sample size of the heat storage characteristic data of the target building envelope has reached the preset number. Only when the preset number is reached will step S504 be executed to meet statistical requirements. The preset number can be set according to actual needs, for example, the preset number is 20.

[0172] Step S604: Based on the heat storage characteristic data of the target building envelope of the space where the air conditioning equipment is located, as well as the heat transfer characteristic data and ventilation characteristic data corresponding to the building envelope, determine the heat capacity of the building envelope of the space where the air conditioning equipment is located.

[0173] Taking the building envelope as a wall as an example, the heat absorbed by the wall is Q. envelop The expression for the curve of Q changing with indoor air temperature t (the expression for the heat balance equation of a building without an indoor heat source) is as follows, where Q HVAC Energy output for air conditioning:

[0174]

[0175] The heat absorption of the wall varies with the indoor air temperature T in The expression for the change in time τ (the general fitting formula for the heat absorption of the wall) is as follows:

[0176] Q envelop =T in (aτ 2 +bτ+c)exp(-dτ+e)+f (4)

[0177] First, based on the air conditioning energy output, indoor air temperature, indoor relative humidity, outdoor air temperature, outdoor relative humidity, whether it is raining and the wind speed range in the heat storage characteristic data of the target building envelope, as well as the heat transfer coefficient and ventilation characteristic parameters of the building envelope, the heat absorption of the wall at different times can be determined by equation (3); then, combined with the indoor air temperature at different times in the heat storage characteristic data of the target building envelope, the goodness of fit of equation (4) is screened, and each parameter (a, b, c, d, e, f) is fitted. The fitting method can be the least squares method or a fitting method based on neural networks, etc., with an accuracy of over 90%, and meets the stability test requirements (the total percentage of the identified parameter error deviation of 10% is over 85%). Integrate the fitted equation, the integration time is from the start time of the indoor unit to the time point when the wall temperature reaches stability, and obtain the total heat gain of the internal building envelope and objects within this time interval. Divide the total heat gain by the temperature difference of the wall during this time period to obtain the heat capacity C of the internal building envelope and objects. envelop .

[0178] Based on this, step S604 above can be achieved through the following process:

[0179] First, based on the heat transfer coefficient and ventilation characteristic parameters of the building envelope where the air conditioning equipment is located, determine the first expression of the building heat balance equation without an indoor heat source (that is, the expression obtained by substituting the heat transfer coefficient and ventilation characteristic parameters of the building envelope into equation (3)).

[0180] Based on the heat storage characteristic data of the target building envelope and the first expression, the heat absorption Q of the following building envelope is calculated. envelop With indoor air temperature T in By fitting the expression for the change in time τ, a second expression is obtained:

[0181] Q envelop =T in (aτ 2 +bτ+c)exp(-dτ+e)+f;

[0182] Then, the second expression is integrated over the target time interval to obtain the total heat gain of the building envelope within the target time interval; where the target time interval is from the moment the indoor unit is turned on to the moment when the surface temperature of the building envelope stabilizes; finally, the heat capacity of the building envelope of the space where the air conditioning equipment is located is determined based on the total heat gain and the surface temperature difference of the building envelope during the target time interval.

[0183] This building feature recognition method makes extensive use of the sensors built into the air conditioning equipment, reducing equipment investment. Compared with building feature recognition methods that do not perform data screening, this data-screening method determines the thermal capacity of the building envelope of the space where the air conditioning equipment is located more accurately.

[0184] Additionally, based on building feature recognition methods, the internal heat source characteristics of the space where the air conditioning equipment is located can be determined. See [link to relevant documentation]. Figure 7 The diagram illustrates a flowchart of an air conditioning control method for determining the internal heat source characteristics of the space where the air conditioning equipment is located. The process for determining the internal heat source characteristics of the space where the air conditioning equipment is located is as follows:

[0185] Step S702: Obtain the target internal heat source characteristic data of the space where the air conditioning equipment is located.

[0186] The target internal heat source characteristic data can be the original dataset mentioned above.

[0187] Step S704: Based on the target internal heat source characteristic data, building envelope heat capacity, air heat capacity, and the corresponding heat transfer characteristic data and ventilation characteristic data of the building envelope of the space where the air conditioning equipment is located, calculate the real-time heat transfer load, real-time ventilation heat load, and real-time heat storage / release of the building envelope of the space where the air conditioning equipment is located, as well as the real-time heat storage / release of the indoor air of the space where the air conditioning equipment is located.

[0188] Step S706: Obtain the real-time heat load of the indoor heat source over multiple days corresponding to the target heat source characteristic data. The real-time heat load of the indoor heat source is equal to the real-time energy output of the air conditioning equipment, minus the real-time heat transfer load, real-time air exchange load, and real-time heat storage / release of the building envelope of the space where the air conditioning equipment is located, and minus the difference between the real-time heat storage / release of the indoor air in the space where the air conditioning equipment is located.

[0189] Step S708: Based on the real-time heat load of the indoor heat source over multiple days, determine the characteristic data of the indoor heat source at different times of the day.

[0190] The real-time heat load corresponding to indoor heat sources such as people, equipment, and lighting can be obtained by subtracting the real-time heat load of the building envelope and ventilation, the real-time heat storage / release of the walls, and the real-time heat storage / release of the indoor air from the real-time energy output of the air conditioning equipment. Finally, the heat load characteristic curve for the whole day can be obtained.

[0191]

[0192] Among them, Q inheat,i Let Q be the average heat load of personnel, equipment, lighting, etc. at time i. HVAC,i Let Δh be the average value of the cooling or heating output of the air conditioner at time i. iLet T be the average enthalpy difference between indoor and outdoor air at time i. in,i Let T be the average indoor air temperature at time i. out,i Let T be the average outdoor air temperature at time i. wall,i Let T be the average wall temperature at time i. wall,i-1 Let T be the average wall temperature at time i-1. air,i Let T be the average air temperature at time i. air,i-1 Let C be the average air temperature at time i-1. m,wall C represents the heat capacity of the wall (i.e., the heat capacity of the building envelope). m,air It is the heat capacity of air.

[0193] The heat load characteristic curves corresponding to indoor heat sources such as personnel, equipment, and lighting are obtained for several days. These curves are then classified using methods such as cluster analysis to obtain the temporal characteristics of the heat load at different times (i.e., internal heat source characteristic data). For example, cluster analysis can be used to classify the dynamic load changes of personnel, equipment, and lighting under different working days.

[0194] This building feature identification method makes extensive use of the sensors built into the air conditioning equipment, reducing equipment investment. It takes into account the real-time heat load of the building envelope, the real-time heat storage / release of the walls, and the real-time heat storage / release of the indoor air, making the determined internal heat source characteristics data of the space where the air conditioning equipment is located more accurate.

[0195] For ease of understanding, the embodiments of the present invention also provide specific implementation processes of the above step S104 under different task types.

[0196] When the task type is scheduled power-on, the above step S104 can be implemented through the following process: First, based on real-time environmental characteristic data and heat transfer characteristic data, calculate the required air conditioning capacity output curves corresponding to multiple preset temperature reaching curves; wherein, the temperature reaching curve is the curve of change of indoor air temperature value over time to the scheduled temperature value; then, based on the required air conditioning capacity output curve corresponding to each temperature reaching curve and the energy efficiency of the air conditioning equipment under different air conditioning load rates, calculate the air conditioning energy consumption value corresponding to each temperature reaching curve; finally, determine the temperature reaching time corresponding to the temperature reaching curve with the smallest air conditioning energy consumption value as the target time required for the space where the air conditioning equipment is located to reach the scheduled temperature value.

[0197] In practice, the air conditioner capacity output curve can be calculated using the following formula during cooling operation:

[0198]

[0199] When operating in heating mode, the air conditioner capacity output curve can be calculated using the following formula:

[0200]

[0201] Among them, Q hvac For air conditioning capacity output, CM air Let KA be the heat capacity of air, KA be the heat transfer coefficient of the building envelope, and Q be the heat capacity of air. in The heat load of the indoor heat source is represented by F, which represents the ventilation characteristic parameter of the building envelope, Δh represents the enthalpy difference between indoor and outdoor air, and T is the heat load of the indoor heat source. in,i-1 Let T be the indoor air temperature at time i-1. in,i Let T be the indoor air temperature at time i. out,i Let RH be the outdoor air temperature at time i. out Outdoor relative humidity, RH in This refers to indoor relative humidity. When indoor relative humidity cannot be measured, it can be calculated as 60%.

[0202] Air conditioning load rate (PLR) equals air conditioning capacity output (Q). hvac Divide by the rated output Q ratio :

[0203]

[0204] The air conditioning energy consumption values ​​corresponding to different schemes (different temperature reaching curves) are calculated using the following formula:

[0205]

[0206] Wherein, COP(PLR) refers to the system energy efficiency COP under different air conditioning load rate PLRs, and t(PLR) refers to the cumulative time t of different schemes under the corresponding air conditioning load rate PLRs.

[0207] Figure 8 The diagram shows multiple temperature reach curves during air conditioning cooling operation, where T... in Indoor air temperature, T set For the predetermined temperature value, the temperature reaching time of the curve corresponding to Scheme 1 is 3 seconds, the temperature reaching time of the curve corresponding to Scheme 2 is 2 seconds, and the temperature reaching time of the curve corresponding to Scheme 3 is 1 second. Figure 9 The diagram illustrates the energy consumption effects of multiple cooling schemes during pre-cooling. The solid line represents the energy efficiency curve as a function of the air conditioning load rate, while the three dashed lines, from left to right, represent the cumulative time curves as a function of the air conditioning load rate for schemes 3, 2, and 1, respectively.

[0208] When the task type is scheduled shutdown, and the heat transfer characteristic data includes the air heat capacity of the space where the air conditioning equipment is located, as well as the heat transfer characteristic data and ventilation characteristic data corresponding to the enclosure structure of the space where the air conditioning equipment is located, the above step S104 can be implemented through the following process: Based on the real-time environmental characteristic data and heat transfer characteristic data, determine the current parameter data; wherein, the current parameter data includes the current indoor air temperature value, the current enthalpy difference between indoor and outdoor air, the current heat transfer coefficient value and the current ventilation characteristic parameter value of the enclosure structure of the space where the air conditioning equipment is located, and the current air heat capacity value; substitute the current parameter data into the temperature change function after the air conditioning is shut down, and calculate the target time required for the space where the air conditioning equipment is located to reach the scheduled temperature value.

[0209] Figure 10 The diagram shows the change in indoor air temperature over time when the unit is scheduled to shut down under cooling conditions. Under cooling operation, the change in indoor temperature after shutdown can be calculated using the following formula:

[0210]

[0211] Under heating operation, the indoor temperature change curve after shutdown can be calculated using the following formula:

[0212]

[0213] Based on the temperature change curve calculated above, determine the time to reach the upper limit of comfort temperature (reserved temperature value).

[0214] For ease of understanding, embodiments of the present invention also provide a detailed flowchart of the above-described air conditioning control method, see [link to documentation]. Figure 11 The flowchart of another air conditioning control method is shown. This method mainly includes the following steps:

[0215] Step S1102: Obtain the spatial location of the indoor unit of the air conditioning equipment in the building.

[0216] Step S1104: Group the indoor units located in the same space into one group.

[0217] Step S1106: Architectural feature identification is performed on the spaces where indoor units of different groups are located to obtain heat transfer feature data of the spaces where air conditioning equipment is located.

[0218] Step S1108: Determine whether the task type is scheduled power-on or scheduled power-off. If the task type is scheduled power-on (pre-cooling or pre-warming), execute steps S1110 to S1114; if the task type is scheduled power-off, execute steps S1116 to S1118.

[0219] Step S1110: Obtain the start-up reservation time of the air conditioning equipment. Before the start-up reservation time, a minutes before the preset judgment time, obtain the outdoor air temperature value, outdoor relative humidity value, and indoor air temperature value. Based on the heat transfer characteristic data of the space where the air conditioning equipment is located, calculate the required air conditioning capacity output curve corresponding to different temperature reaching curves.

[0220] Step S1112: Based on the energy efficiency curve corresponding to the air conditioning load rate and the required air conditioning capacity output curve corresponding to different temperature reaching curves, calculate the total energy consumption for reaching the temperature, select the temperature reaching time b seconds corresponding to the temperature reaching curve with the minimum total energy consumption for reaching the temperature, and set the capacity output control coefficient TRBF = bs for the air conditioning equipment.

[0221] Step S1114: Turn on the indoor unit of the air conditioner b seconds before the scheduled time.

[0222] Step S1116: Obtain the shutdown reservation time of the air conditioning equipment. Before the shutdown reservation time, a minutes before the preset judgment time, obtain the outdoor air temperature value, outdoor relative humidity value, and indoor air temperature value. Calculate the time c seconds required for the indoor air temperature to reach the upper limit of comfort temperature based on the heat transfer characteristic data of the space where the air conditioning equipment is located.

[0223] Step S1118: Turn off the indoor unit of the air conditioner c seconds before the scheduled time.

[0224] Thus, by performing building feature recognition, heat transfer characteristic data of the space where the air conditioning equipment is located is obtained. Based on the heat transfer characteristic data of the space where the air conditioning equipment is located, the optimization time for precooling / preheating and early shutdown is determined. The data-driven recognition method solves the problems of digitizing and informatizing the heat storage capacity of the air inside the building and the building envelope, and its application.
