[0062] The implementation, functional features and advantages of the present application will be further described with reference to the embodiments and the accompanying drawings. Detailed implementation manners
[0063] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0064] In the use of an air conditioning device (such as an air conditioner), it is usually necessary to quantify the power consumption corresponding to the temperature and humidity changes, so as to determine the sensible heat / latent heat ratio of the air conditioner in various situations, and achieve the effect of estimating the energy consumption of the air conditioner. The current method for calculating the sensible heat / sensible heat ratio of the air conditioner is mainly to calculate the energy consumption generated by the temperature change and the energy consumption generated by the humidity change per unit time, and then calculate the ratio between them and the total energy consumption.
[0065] However, the existing technical solutions for obtaining energy consumption have some defects. First, the energy consumption calculation needs to rely on various devices such as enthalpy difference experiments, which have high requirements for the devices and are difficult to be widely applied. Moreover, with the change of temperature and humidity, the energy consumed per unit cooling / dehumidification will also change dynamically, resulting in low accuracy of the obtained energy consumption. Therefore, there is an urgent need for an energy consumption acquisition method that can realize quantitative detection of temperature and humidity energy consumption changes and facilitate accurate calculation of sensible heat and latent heat.
[0066] Based on this, the present application proposes a method for obtaining the energy consumption of the air conditioning device in the first embodiment. Please refer to Figure 1 The method for obtaining the energy consumption of the air conditioning device includes:
[0067] Step S10, obtaining the temperature change amount and humidity change amount corresponding to the current cycle and the previous cycle respectively;
[0068] In the embodiments of the present application, when obtaining the energy consumption of the air conditioning device, the usage time of the air conditioning device can be divided into multiple cycles, and specifically, the temperature change amount and humidity change amount are obtained respectively within each cycle. In this way, within adjacent cycles, the temperature and humidity change amounts are both small, so that the temperature adjustment power and humidity adjustment power will not change significantly. Therefore, according to the temperature change amount, humidity change amount and energy consumption within two adjacent cycles, the temperature change energy consumption and humidity change energy consumption within the current cycle can be determined, and then the corresponding sensible heat ratio and latent heat ratio can be obtained.
[0069] It should be noted that the shorter the duration of the said period is set, the more accurate the calculated energy consumption is, while the longer the duration of the period is set, the lower the accuracy of the energy consumption. However, if the duration of the period is set too short, the computational amount will be larger and more computing resources will be consumed. Therefore, the user can set a suitable period duration (such as 30 s) according to the requirements.
[0070] Specifically, in the previous period and the current period, the temperature change amount and humidity change amount in the environment can be read through the temperature sensor and humidity sensor.
[0071] Exemplarily, calculate the temperature change value Δt(i) = t(i) - t(i - 1) generated in the current period, where Δt(i) is the temperature change amount in the current period, t(i) is the temperature value at the end time point of the current period, and t(i - 1) is the temperature value at the start time point of the current period; calculate the humidity change value Δh(i) = h(i) - h(i - 1) generated in this period, where Δh(i) is the humidity change amount in the current period, h(i) is the humidity value at the end time point of the current period, and h(i - 1) is the humidity value at the start time point of the current period. It can be understood that in the previous period, the temperature change amount is Δt(i - 1) and the humidity change amount is Δh(i - 1).
[0072] Step S20, obtain the energy consumption generated in the current period and the energy consumption generated in the previous period;
[0073] In the embodiment of the present application, taking cooling and dehumidification as an example, the indoor is cooled and dehumidified by the air conditioning equipment, and at the same time, the energy consumption (power consumption) generated in the current period and the previous period is obtained according to the electricity meter or the power / energy consumption prediction model. It should be noted that the energy consumption therein is the combined energy consumption of cooling and dehumidification.
[0074] Exemplarily, the power consumption generated in the current period is E(i), and the power consumption generated in the previous period is E(i - 1).
[0075] Step S30, calculate the energy consumption generated by the temperature change in the current period and the energy consumption generated by the humidity change in the current period according to the temperature change amount, humidity change amount, energy consumption in the current period, and energy consumption in the previous period of the current period and the previous period.
[0076] Specifically, after obtaining the temperature change amount, humidity change amount, energy consumption in the current cycle, and energy consumption in the previous cycle, the technical solution of the embodiment of the present application can first determine the cooling power and dehumidification power in the previous cycle and the current cycle, and then combine the cycle time to calculate the energy consumption (cooling power consumption) generated by the temperature change in the current cycle and the energy consumption (dehumidification power consumption) generated by the humidity change in the current cycle. It can be understood that in two adjacent cycles, it can be considered that the cooling power x and the dehumidification power are constant. In two adjacent cycles, the following regulations are respectively satisfied: multiplying the cooling power by the temperature change amount gives the cooling power consumption, multiplying the dehumidification power by the humidity change amount gives the dehumidification power consumption, and the sum of the cooling power consumption and the dehumidification power consumption is equal to the total energy consumption. Therefore, according to the above relationship, the cooling power and dehumidification power in the current cycle can be calculated, and then multiplied by the current temperature change amount and humidity change amount respectively to obtain the cooling power consumption and dehumidification power consumption in the current cycle.
[0077] After obtaining the cooling power consumption and dehumidification power consumption in the current cycle, the sensible heat ratio and latent heat ratio in the current cycle can be calculated. It should be noted that the sensible heat ratio is the ratio between the cooling power consumption and the total energy consumption, and the latent heat ratio is the ratio between the dehumidification power consumption and the total energy consumption. The calculation of the sensible heat ratio and the latent heat ratio can provide a strong data basis for subsequent energy-saving control, comfort, and building model design of air-conditioning equipment.
[0078] In the embodiment of the present application, the reason why the energy consumption generated by the temperature change in the current cycle and the energy consumption generated by the humidity change in the current cycle can be calculated based on the temperature change amount, humidity change amount, energy consumption in the current cycle, and energy consumption in the previous cycle is that in any cycle, the following equation is satisfied:
[0079] Unit cooling power consumption x * Cooling amplitude Δt = Cooling power consumption Et;
[0080] Unit dehumidification power consumption y * Dehumidification amplitude Δh = Dehumidification power consumption Eh;
[0081] Cooling power consumption Et + Dehumidification power consumption Eh = Total power consumption E.
[0082] It can be understood that in a single cycle, the above equations all hold. However, referring to Figure 2 the statistical schematic diagram showing the change of temperature and humidity over time, when the air-conditioning equipment operates at a constant power, with the change of temperature and humidity, the energy consumed per unit cooling / dehumidification will also change dynamically, that is, x and y will change dynamically. Therefore, the above formulas are only applicable to short cycles, Figure 2 the cycles in are only examples and do not impose any limitations on the technical solution of the embodiment of the present application.
[0083] The temperature and humidity are continuous and smooth. x and y are elementary functions based on the changes in temperature and humidity and are also continuous and smooth. Therefore, when the number of cycles → +∞, the latent heat and sensible heat energy consumption can be calculated using integration.
[0084] For example, for a fixed period T, if T → +0, that is, the number of cycles → +∞, then:
[0085]
[0086] Therefore, in practical applications, a relatively small cycle duration can be adopted to approximately calculate x and y for each cycle, so as to obtain the power consumption x for unit temperature reduction and the power consumption y for unit dehumidification within each short cycle.
[0087] The technical solution of the embodiment of the present application calculates the energy consumption generated by the temperature change and the energy consumption generated by the humidity change in the current cycle by obtaining the temperature change amount, humidity change amount, energy consumption, etc. of the current cycle and the previous cycle in a cycle. It realizes the perception and calculation of temperature and humidity energy consumption through a quantitative method, without the need for an enthalpy difference experimental device to calculate and obtain the energy consumption, and can be widely applied to a wider range of usage scenarios. Moreover, in the technical solution of the embodiment of the present application, only the temperature and humidity change amounts and energy consumption amounts of two adjacent cycles are used to calculate the energy consumption corresponding to the temperature change and humidity change in the current cycle respectively. Since the temperature and humidity differences between adjacent cycles are small, it overcomes the technical defect that the energy consumed per unit temperature reduction / dehumidification is different when the temperature and humidity are at different values, which affects the accuracy of the energy consumption amount. And because the enthalpy difference experiment is completed in the laboratory and does not consider the actual operation situation, while the technical solution of the present application adopts a calculation method that is separated from the laboratory and based on the actual operation situation, the obtained energy consumption amount is more accurate, thus solving the technical problem of the low accuracy of obtaining the energy consumption of temperature change and humidity change per unit time by using an enthalpy difference experimental device in the prior art.
[0088] In a possible implementation manner, the step of calculating the energy consumption generated by the temperature change in the current cycle and the energy consumption generated by the humidity change in the current cycle according to the temperature change amount, humidity change amount, energy consumption of the current cycle, and energy consumption of the previous cycle includes:
[0089] Step S31, calculating a first unit energy consumption generated by unit temperature change and a second unit energy consumption generated by unit humidity change according to the temperature change amount, humidity change amount, energy consumption of the current cycle, and energy consumption of the previous cycle;
[0090] In the embodiments of the present application, it should be noted that the first unit energy consumption refers to the energy (electric energy) required to lower the temperature of the environment by 1°C, and the second unit energy consumption refers to the energy required to reduce the humidity of the environment by 1%. Since it can be approximately considered that the first unit energy consumption and the second unit energy consumption have not changed in the previous cycle and the current cycle, the values of the first unit energy consumption and the second unit energy consumption can be calculated based on the temperature change, humidity change, current cycle energy consumption, and previous cycle energy consumption in the previous cycle and the current cycle, so as to calculate the energy consumed for cooling and the energy consumed for dehumidification in the current cycle.
[0091] Step S32: Calculate the energy consumption generated by the temperature change in the current cycle according to the temperature change amount in the current cycle and the first unit energy consumption.
[0092] Step S33: Calculate the energy consumption generated by the humidity change in the current cycle according to the humidity change amount in the current cycle and the second unit energy consumption.
[0093] It can be understood that after the first unit energy consumption x(i) and the second unit energy consumption y(i) are both calculated, the cooling power consumption Et(i) = E(i) * T * x(i) / (x(i) + y(i)) in the current cycle and the dehumidification power consumption Eh(i) = E(i) * T * y(i) / (x(i) + y(i)) in the current cycle can be calculated respectively. Here, Et(i) is the cooling power consumption, that is, the energy consumption generated by the temperature change in the current cycle, E(i) is the total energy consumption in the current cycle, T is the cycle duration, x(i) is the first unit energy consumption, y(i) is the second unit energy consumption, and Eh(i) is the dehumidification power consumption, that is, the energy consumption generated by the humidity change in the current cycle.
[0094] Furthermore, after obtaining the cooling power consumption and dehumidification power consumption in the current cycle, the sensible heat ratio and latent heat ratio in the current cycle can be calculated. Among them, the sensible heat ratio = Et(i) / (Et(i) + Eh(i)); the latent heat ratio = Eh(i) / (Et(i) + Eh(i)).
[0095] In a possible implementation manner, the step of calculating the first unit energy consumption generated by unit temperature change and the second unit energy consumption generated by unit humidity change according to the temperature change amount, humidity change amount, current cycle energy consumption, and previous cycle energy consumption in the current cycle and the previous cycle includes:
[0096] Step S311: Construct a first relational expression according to the temperature change amount, humidity change amount, and current cycle energy consumption in the current cycle.
[0097] The first relationship is an equation for the relationship between physical quantities such as temperature change, humidity change, first unit energy consumption, second unit energy consumption and energy consumption of the current cycle in the current cycle.
[0098] Exemplarily, the first relationship is: Δt(i)*x(i)+Δh(i)*y(i)=E(i), wherein Δt(i) is the temperature change in the previous cycle, Δh(i) is the humidity change in the current cycle, x(i) is the first unit energy consumption, y(i) is the second unit energy consumption, and E(i) is the total energy consumption in the current cycle.
[0099] Step S312, constructing a second relationship according to the humidity change amount, the humidity change amount, and the energy consumption of the previous cycle in the previous cycle;
[0100] Similarly, the second relational expression is an equation for the relationship between physical quantities such as the temperature change, humidity change, first unit energy consumption, second unit energy consumption and energy consumption in the previous cycle in the previous cycle.
[0101] Exemplarily, the second relationship is: Δt(i-1)*x(i)+Δh(i-1)*y(i)=E(i-1), wherein Δt(i-1) is the temperature change in the previous cycle, Δh(i-1) is the humidity change in the previous cycle, x(i) is the first unit energy consumption, y(i) is the second unit energy consumption, and E(i-1) is the total energy consumption in the previous cycle.
[0102] Step S313: Calculate the first unit energy consumption generated by the unit temperature change and the second unit energy consumption generated by the unit humidity change according to the first relationship and the second relationship.
[0103] In an embodiment of the present application, after constructing the first relationship and the second relationship, the first relationship and the second relationship can be combined and solved as a system of two linear equations to obtain the first unit energy consumption and the second unit energy consumption of the current period, which are the unknowns in the system of equations.
[0104] In a possible implementation, after the step of calculating the energy consumption generated by the temperature change in the current cycle and the energy consumption generated by the humidity change in the current cycle, the step further includes:
[0105] Step S30, calculating the total energy consumption caused by temperature changes and the total energy consumption caused by humidity changes during the operation of the air conditioning equipment according to the energy consumption caused by temperature changes in the historical period and the energy consumption caused by humidity changes in the historical period;
[0106] In the embodiments of the present application, the energy consumption generated by temperature changes and the energy consumption generated by humidity changes in each cycle are calculated according to the methods of steps S10 to S20, and the sums are calculated respectively, so as to obtain the total energy consumption generated by temperature changes and the total energy consumption generated by humidity changes during the operation of the air conditioning equipment.
[0107] Step S40, calculate the total energy consumption during the operation of the air conditioning equipment according to the total energy consumption generated by temperature changes and the total energy consumption generated by humidity changes during the operation of the air conditioning equipment.
[0108] Among them, the total energy consumption during the operation of the air conditioning equipment can be obtained by calculating the sum of the total energy consumption generated by temperature changes and the total energy consumption generated by humidity changes during the operation of the air conditioning equipment, or the total energy consumption during the operation of the air conditioning equipment can be obtained through an electricity meter module or a power / energy consumption prediction model, so as to calculate the total power consumption E = ∑E(i).
[0109] Further, after the steps of obtaining the total energy consumption generated by temperature changes and the total energy consumption generated by humidity changes during the operation of the air conditioning equipment, it may further include:
[0110] Step S50, display the total energy consumption, the total energy consumption generated by temperature changes, and the total energy consumption generated by humidity changes during the operation of the air conditioning equipment.
[0111] Obtain the total cooling power consumption E = ∑Et(i), the total dehumidification power consumption E = ∑Eh(i), and the total power consumption E = ∑E(i), and display them to the user in a visual manner, so that the user can clearly see how much electric energy is used for cooling, how much electric energy is used for dehumidification, and what the total energy consumption is during the operation of this air conditioning equipment.
[0112] Further, on the basis of determining the total energy consumption, the total energy consumption generated by temperature changes, and the total energy consumption generated by humidity changes during the operation of the air conditioning equipment, the sensible heat ratio and latent heat ratio of the air conditioning equipment from startup to the current cycle can be calculated.
[0113] Exemplarily, during the cycle from startup to the current time, calculate the current operation sensible heat ratio = ∑Et(i) / (∑Et(i)+∑Eh(i)); during the cycle from startup to the current time, calculate the current operation latent heat ratio = ∑Eh(i) / (∑Et(i)+∑Eh(i)).
[0114] It should be noted that the above specific embodiments are only used to understand the present application, and do not constitute a limitation on the method for obtaining the energy consumption of the air conditioning equipment of the present application. Based on this technical concept, more forms of simple transformations are within the protection scope of the present application.
[0115] In another embodiment of the present application, for the same or similar content as in the above embodiment, reference may be made to the above description and will not be repeated hereinafter. On this basis, please refer to Figure 3 , an embodiment of the present application further provides a control method for an air conditioning device, and the control method for the air conditioning device includes:
[0116] Step A10, obtaining the temperature-humidity energy consumption ratio of the current cycle;
[0117] Referring to the method for calculating the energy consumption generated by the temperature change in the current cycle and the energy consumption generated by the humidity change in the current cycle in the previous embodiment, calculate the temperature-humidity energy consumption ratio of the current cycle, where the temperature-humidity energy consumption ratio may be the sensible heat ratio or the latent heat ratio. Among them, the sensible heat ratio is equal to the ratio between the energy consumption generated by the temperature change and the total energy consumption, and the latent heat ratio is equal to the ratio between the energy consumption generated by the humidity change and the total energy consumption.
[0118] In the embodiment of the present application, the sensible heat ratio may be taken as an example to measure the current energy-saving state of the air conditioning device, so as to determine the control mode of the air conditioning device and adjust the energy-saving state of the air conditioning device.
[0119] Step A20, calculating the first average temperature-humidity energy consumption ratio of all cycles of the air conditioning device;
[0120] In the embodiment of the present application, the first average temperature-humidity energy consumption ratio is the temperature-humidity energy consumption ratio within the time from the first cycle since the air conditioning device is turned on to the current cycle, and can be obtained by calculating the ratio between the total energy consumption of all temperature changes (or the total energy consumption of humidity changes) since the device is turned on and the total energy consumption. Taking the sensible heat ratio as the temperature-humidity energy consumption ratio as an example, the first average temperature-humidity energy consumption ratio can be understood as the global average sensible heat ratio from the first cycle to the current cycle.
[0121] Step A30, calculating the second average temperature-humidity energy consumption ratio of the current cycle and multiple previous historical cycles of the air conditioning device;
[0122] In the embodiment of the present application, the second average temperature-humidity energy consumption ratio is the average sensible heat ratio of a preset number of cycles counted forward from the current cycle, and can be obtained by calculating the ratio between the total energy consumption of temperature changes (or the total energy consumption of humidity changes) of a preset number of cycles counted forward from the current cycle and the energy consumption within the preset number of cycles, and can be understood as the average sensible heat ratio of the recent preset number of cycles.
[0123] Step A40, determining the control mode of the air conditioning device according to the first average temperature-humidity energy consumption ratio, the second average temperature-humidity energy consumption ratio, and the target temperature-humidity energy consumption ratio, and controlling the air conditioning device to operate according to the determined control mode.
[0124] It should be noted that the first average temperature and humidity energy consumption ratio and the second average temperature and humidity energy consumption ratio can be used to characterize the global energy-saving state and the recent energy-saving state of the air-conditioning equipment respectively. Therefore, after determining the global energy-saving state and the recent energy-saving state of the air-conditioning equipment, the energy-saving state of the air-conditioning equipment can be adjusted according to the preset control mode adjustment strategy, so as to realize the adjustment of the energy-saving state of the air-conditioning equipment, make the air-conditioning equipment always operate in the best energy-saving state, balance the energy saving and comfort when using the air-conditioning equipment, realize the energy-saving control of sensible heat and latent heat, and improve the intelligent level and user experience of the air-conditioning equipment.
[0125] Exemplarily, the value of the sensible heat ratio can be used to characterize the energy-saving state of the air-conditioning equipment (such as an air conditioner). For example: strong energy saving (sensible heat ratio = 0.9), medium energy saving (sensible heat ratio = 0.8), weak energy saving (sensible heat ratio = 0.7).
[0126] In another possible implementation manner, the step of determining the control mode of the air-conditioning equipment according to the first average temperature and humidity energy consumption ratio, the second average temperature and humidity energy consumption ratio, and the target temperature and humidity energy consumption ratio, and controlling the air-conditioning equipment to operate according to the determined control mode includes:
[0127] Step A41, when the difference between the first average temperature and humidity energy consumption ratio and the target temperature and humidity energy consumption ratio is within the first preset range, keep the current operation mode of the air-conditioning equipment and continue to operate.
[0128] It can be understood that the target temperature and humidity energy consumption ratio is the temperature and humidity energy consumption ratio that can make the air-conditioning equipment operate in the best energy-saving state. For example, when the temperature and humidity energy consumption ratio is the sensible heat ratio, the corresponding target sensible heat ratio can be 0.8 (when the temperature and humidity energy consumption ratio is the latent heat ratio, the corresponding target sensible heat ratio can be 0.2), and the first preset range can be within a certain range around the target sensible heat ratio of 0.8. When the first average temperature and humidity energy consumption ratio (global average sensible heat ratio) is within the first preset range of the target sensible heat ratio, it can be considered that the current air-conditioning equipment is in a relatively appropriate energy-saving state and does not need to be adjusted.
[0129] As an embodiment, the first preset range can be (-0.1, +0.1).
[0130] In a possible implementation manner, the step of determining the control mode of the air-conditioning equipment according to the first average temperature and humidity energy consumption ratio, the second average temperature and humidity energy consumption ratio, and the target temperature and humidity energy consumption ratio, and controlling the air-conditioning equipment to operate according to the determined control mode includes:
[0131] Step A42, when the difference between the first average temperature and humidity energy consumption ratio and the target temperature and humidity energy consumption ratio is less than or equal to the first preset threshold, judge whether the difference between the second average temperature and humidity energy consumption ratio and the target temperature and humidity energy consumption ratio is greater than or equal to the second preset threshold;
[0132] In the embodiments of the present application, taking the sensible heat ratio of the temperature and humidity energy consumption ratio as an example, when the difference between the first average temperature and humidity energy consumption ratio and the target temperature and humidity energy consumption ratio is less than or equal to the first preset threshold, it can be determined that the global average temperature and humidity energy consumption ratio (sensible heat ratio) of the air conditioning equipment is less than the target temperature and humidity energy consumption ratio. From a global perspective, the air conditioning equipment is in a weak energy-saving state under the current energy-saving state. At this time, it is necessary to combine the second average temperature and humidity energy consumption ratio of the air conditioning equipment in the recent preset number of cycles to determine whether to adjust the energy-saving state and control mode of the air conditioning equipment.
[0133] As an embodiment, the first preset threshold is -0.1.
[0134] Step A43, when the difference between the second average temperature and humidity energy consumption ratio and the target temperature and humidity energy consumption ratio is greater than or equal to the second preset threshold, maintain the current operating mode of the air conditioning equipment and continue to operate;
[0135] In the embodiments of the present application, taking the sensible heat ratio of the temperature and humidity energy consumption ratio as an example, when the difference between the second average temperature and humidity energy consumption ratio and the target temperature and humidity energy consumption ratio is greater than or equal to the second preset threshold, this indicates that although the air conditioning equipment is in a weak energy-saving state from a global perspective, recently, the air conditioning equipment is in a strong energy-saving state. Therefore, as long as the current operating mode is maintained, the recent strong energy-saving state will affect the global energy-saving state, and ultimately make the air conditioning equipment tend to the medium energy-saving state, maintaining a good comfort level and energy-saving effect, and ensuring the user experience.
[0136] As an embodiment, the second preset threshold is 0.1.
[0137] Step A44, when the difference between the second average temperature and humidity energy consumption ratio and the target temperature and humidity energy consumption ratio is less than the second preset threshold, adjust the operating frequency and fan speed of the air conditioning equipment according to a preset ratio.
[0138] In the embodiments of the present application, taking the sensible heat ratio of the temperature and humidity energy consumption ratio as an example, when the difference between the second average temperature and humidity energy consumption ratio and the target temperature and humidity energy consumption ratio is less than or the second preset threshold, this indicates that when the air conditioning equipment is in a weak energy-saving state from a global perspective, recently, the air conditioning equipment is in a medium energy-saving or weak energy-saving state. Therefore, if it continues with the current operating mode, the air equipment will still be in a weak energy-saving state from a global perspective, and it is necessary to further improve the energy-saving effect of the air conditioning equipment by adjusting the operating frequency and fan speed of the air conditioning equipment, and ultimately make the air conditioning equipment tend to the medium energy-saving state, maintaining a good comfort level and energy-saving effect, and ensuring the user experience.
[0139] It should be noted that when it is necessary to increase the sensible heat ratio (or decrease the latent heat ratio), it is necessary to increase the wind speed and decrease the operating frequency. The preset ratio can be set according to user needs to achieve the control effect of increasing the wind speed and decreasing the frequency.
[0140] Further, in a possible implementation manner, the step of adjusting the operating frequency and the fan speed of the air conditioning device according to a preset ratio when the difference between the second average temperature-humidity energy consumption ratio and the target temperature-humidity energy consumption ratio is less than a second preset threshold includes:
[0141] Step A441, when the temperature-humidity energy consumption ratio is the ratio of the energy consumption generated by temperature change to the total energy consumption, decrease the operating frequency according to a first preset ratio, and increase the fan speed according to a second preset ratio;
[0142] In the embodiment of the present application, a method for adjusting the operating frequency and the fan speed of the air conditioning device when the temperature-humidity energy consumption ratio is the sensible heat ratio (the ratio of the energy consumption generated by temperature change to the total energy consumption) is disclosed. That is, it is necessary to increase the sensible heat ratio to improve the energy-saving effect. Further, decrease the operating frequency according to a first preset ratio, and increase the fan speed according to a second preset ratio, so as to increase the sensible heat ratio and improve the energy-saving effect.
[0143] Step A442, when the temperature-humidity energy consumption ratio is the ratio of the energy consumption generated by humidity change to the total energy consumption, increase the operating frequency according to a first preset ratio, and decrease the fan speed according to a second preset ratio.
[0144] In the embodiment of the present application, a method for adjusting the operating frequency and the fan speed of the air conditioning device when the temperature-humidity energy consumption ratio is the latent heat ratio (the ratio of the energy consumption generated by humidity change to the total energy consumption) is disclosed. Since the sum of the sensible heat ratio and the latent heat ratio is always 1, when the sensible heat ratio rises, the latent heat ratio drops, and the two are inversely proportional. Therefore, when the difference between the second latent heat ratio and the target temperature-humidity energy consumption ratio is less than the second preset threshold, it indicates that the sensible heat ratio of the current air conditioning device is too high and it is in a strong energy-saving mode. It is necessary to reduce the energy-saving effect to balance comfort. Therefore, at this time, it is necessary to decrease the sensible heat ratio. Contrary to Step A441, in this step, it is necessary to increase the operating frequency according to a first preset ratio, and decrease the fan speed according to a second preset ratio, so as to increase the latent heat ratio, decrease the sensible heat ratio and reduce the energy-saving effect.
[0145] In a possible implementation manner, the step of determining the control mode of the air conditioning device according to the first average temperature-humidity energy consumption ratio, the second average temperature-humidity energy consumption ratio, and the target temperature-humidity energy consumption ratio, and controlling the air conditioning device to operate according to the determined control mode includes:
[0146] Step A45: When the difference between the first average temperature-humidity energy consumption ratio and the target temperature-humidity energy consumption ratio is greater than or equal to the third preset threshold, determine whether the difference between the second average temperature-humidity energy consumption ratio and the target temperature-humidity energy consumption ratio is less than or equal to the fourth preset threshold;
[0147] In the embodiments of the present application, taking the temperature-humidity energy consumption ratio as the sensible heat ratio as an example, when the difference between the first average temperature-humidity energy consumption ratio and the target temperature-humidity energy consumption ratio is greater than or equal to the third preset threshold, it can be determined that the global average temperature-humidity energy consumption ratio (sensible heat ratio) of the air conditioning equipment is greater than the target temperature-humidity energy consumption ratio. From a global perspective, the air conditioning equipment is in a strong energy-saving state under the current energy-saving state. At this time, it is necessary to combine the second average temperature-humidity energy consumption ratio of the air conditioning equipment in the recent preset number of cycles to determine whether to adjust the control mode and energy-saving state of the air conditioning equipment.
[0148] As an embodiment, the third preset threshold is 0.1.
[0149] Step A46: When the difference between the second average temperature-humidity energy consumption ratio and the target temperature-humidity energy consumption ratio is less than or equal to the fourth preset threshold, maintain the current operation mode of the air conditioning equipment and continue to operate;
[0150] In the embodiments of the present application, taking the temperature-humidity energy consumption ratio as the sensible heat ratio as an example, when the difference between the second average temperature-humidity energy consumption ratio and the target temperature-humidity energy consumption ratio is less than or equal to the fourth preset threshold, this indicates that although the air conditioning equipment is in a strong energy-saving state from a global perspective, recently, the air conditioning equipment is in a weak energy-saving state. Therefore, as long as the current operation mode is maintained, the recent weak energy-saving state will affect the global energy-saving state, and ultimately make the air conditioning equipment tend to a medium energy-saving state, maintaining a good comfort level and energy-saving effect, and ensuring the user experience.
[0151] As an embodiment, the fourth preset threshold is -0.1.
[0152] Step A47: When the difference between the second average temperature-humidity energy consumption ratio and the target temperature-humidity energy consumption ratio is greater than the fourth preset threshold, adjust the operation frequency and fan speed of the air conditioning equipment according to a preset ratio.
[0153] In the embodiment of the present application, taking the sensible heat ratio as an example of the temperature-humidity energy consumption ratio, when the difference between the second average temperature-humidity energy consumption ratio and the target temperature-humidity energy consumption ratio is greater than the fourth preset threshold, this indicates that when the air conditioning equipment is in a strong energy-saving state from a global perspective, but recently, the air conditioning equipment is in a medium energy-saving or strong energy-saving state. Therefore, if the current operating mode continues, the global perspective of the air equipment will still be in a strong energy-saving state. It is necessary to further reduce the energy-saving effect of the air conditioning equipment by adjusting the operating frequency and fan speed of the air conditioning equipment, and finally make the air conditioning equipment tend to the medium energy-saving state, maintain a good comfort level and energy-saving effect, and ensure the user experience.
[0154] Further, in a possible implementation manner, the step of adjusting the operating frequency and fan speed of the air conditioning equipment according to a preset ratio when the difference between the second average temperature-humidity energy consumption ratio and the target temperature-humidity energy consumption ratio is greater than the fourth preset threshold includes:
[0155] Step A471, when the temperature-humidity energy consumption ratio is the ratio of the energy consumption generated by temperature change to the total energy consumption, increase the operating frequency according to the first preset ratio, and decrease the fan speed according to the second preset ratio;
[0156] In the embodiment of the present application, a method for adjusting the operating frequency and fan speed of the air conditioning equipment when the temperature-humidity energy consumption ratio is the sensible heat ratio (the ratio of the energy consumption generated by temperature change to the total energy consumption) is disclosed, that is, it is necessary to reduce the sensible heat ratio to reduce the energy-saving effect, and then increase the operating frequency according to the first preset ratio, and decrease the fan speed according to the second preset ratio, so as to reduce the sensible heat ratio and the energy-saving effect.
[0157] Step A472, when the temperature-humidity energy consumption ratio is the ratio of the energy consumption generated by humidity change to the total energy consumption, decrease the operating frequency according to the first preset ratio, and increase the fan speed according to the second preset ratio.
[0158] In the embodiment of the present application, a method for adjusting the operating frequency and fan speed of the air conditioning equipment when the temperature-humidity energy consumption ratio is the latent heat ratio (the ratio of the energy consumption generated by humidity change to the total energy consumption) is disclosed. Since the sum of the sensible heat ratio and the latent heat ratio is always 1, when the sensible heat ratio rises, the latent heat ratio drops, and the two are inversely proportional. Therefore, when the difference between the second latent heat ratio and the target temperature-humidity energy consumption ratio is greater than the fourth preset threshold, it indicates that the sensible heat ratio of the current air conditioning equipment is too low and it is in a weak energy-saving mode, and it is necessary to improve the energy-saving effect. Therefore, at this time, it is necessary to increase the sensible heat ratio. Contrary to step A471, in this step, it is necessary to decrease the operating frequency according to the first preset ratio, and increase the fan speed according to the second preset ratio, so as to reduce the latent heat ratio, increase the sensible heat ratio and improve the energy-saving effect.
[0159] In a feasible embodiment, taking the sensible heat ratio as an example of the temperature-humidity energy consumption ratio, assuming the target temperature-humidity energy consumption ratio is 0.8, first obtain the sensible heat ratio Q(i) of the current period, then calculate the global average sensible heat ratio Qt(i) from the 1st to the i-th period, then calculate the average sensible heat ratio Qn(i) of the past N periods from the (i - N + 1)-th to the i-th period, and finally calculate Qt(i) - 0.8 and Qn(i) - 0.8, and control and adjust the energy-saving state of the air-conditioning equipment according to the respective values of Qt(i) - 0.8 and Qn(i) - 0.8 and Table 1 below. Among them, the energy-saving state may include under-energy-saving, normal energy-saving, and over-energy-saving, or be called weak energy-saving, medium energy-saving, and strong energy-saving.
[0160]
[0161] Table 1
[0162] Among them, the strategy for reducing energy-saving is to reduce the air volume and increase the frequency according to a specific ratio (reduce the sensible heat ratio and increase the latent heat ratio); while the strategy for enhancing energy-saving is to increase the air volume and reduce the frequency according to a specific ratio (increase the sensible heat ratio and reduce the latent heat ratio).
[0163] Further, the specific steps of the control method of the air-conditioning equipment in the embodiment of the present application are as follows Figure 4 shown. First, the air conditioner is turned on, and the current running energy-saving mode and the corresponding sensible heat ratio are obtained. Every time interval T (30 s), the following logic (cycle i) is executed: obtain the sensible heat ratio Q(i) of the current period, calculate the average sensible heat ratio Qt(i) from the 1st to the i-th period, and calculate the average sensible heat ratio Qn(i) from the (i - N + 1)-th to the i-th period; determine the magnitude relationship between Qn(i) - 0.8, Qt(i) - 0.8 and 0.1, and execute the energy-saving enhancement / maintenance / reduction strategy according to two-dimensional segmentation.
[0164] In a possible implementation manner, the step of obtaining the temperature-humidity energy consumption ratio of the current period includes:
[0165] Step A11, obtain the temperature change amount and humidity change amount corresponding to the current period and the previous period respectively;
[0166] Step A12, obtain the energy consumption generated in the current period and the energy consumption generated in the previous period;
[0167] Step A13, calculate the energy consumption generated by the temperature change in the current period and the energy consumption generated by the humidity change in the current period according to the temperature change amount, humidity change amount, energy consumption in the current period and energy consumption in the previous period;
[0168] Step A14, calculate the temperature-humidity energy consumption ratio of the current period according to the energy consumption generated by the temperature change in the current period and the energy consumption generated by the humidity change in the current period.
[0169] In the embodiments of the present application, it should be noted that the step of obtaining the temperature-humidity energy consumption ratio of the current cycle adopts the execution method of steps S10 to S30 in the previous embodiment, which will not be elaborated here. It is used to obtain the energy consumption generated by the temperature change in the current cycle and the energy consumption generated by the humidity change in the current cycle. Then, on the basis of determining the total energy consumption during the operation of the air conditioning equipment, the total energy consumption generated by the temperature change, and the total energy consumption generated by the humidity change, the temperature-humidity energy consumption ratio (sensible heat ratio or latent heat ratio) of the air conditioning equipment from startup to the current cycle can be calculated.
[0170] Exemplarily, during the cycle from startup to the current time, calculate the current running sensible heat ratio = ∑Et(i) / (∑Et(i)+∑Eh(i)); during the cycle from startup to the current time, calculate the current running latent heat ratio = ∑Eh(i) / (∑Et(i)+∑Eh(i)).
[0171] The technical solution of the embodiments of the present application implements the control and adjustment of the air conditioning equipment based on the obtained temperature-humidity energy consumption ratio (sensible heat ratio and latent heat ratio) of the air conditioning equipment, enabling the air conditioning equipment to be in the best operating state as much as possible, avoiding the phenomenon of excessive energy consumption or overly strong energy saving affecting comfort, and achieving long-term stable / short-term flexible energy-saving control, thereby enhancing the user experience.
