[0003] The present application relates to the field of electrical control technology, and in particular to an air conditioning device and an energy consumption acquisition method, a control method, a device and a computer storage medium thereof. Background Art

[0004] When using air conditioning equipment (such as air conditioners), it's often necessary to quantify the power consumption associated with temperature and humidity changes. This allows for determining the sensible heat / latent heat ratio of the air conditioner under various conditions, thereby estimating its energy consumption. Current methods for calculating the sensible heat / latent heat ratio primarily calculate the energy consumption associated with temperature and humidity changes per unit time, and then calculate the ratio between these values ​​and the total energy consumption.

[0005] However, existing energy consumption measurement technologies have several drawbacks. First, energy consumption calculations rely on multiple instruments, such as enthalpy difference experiments, which are demanding and difficult to apply on a large scale. Furthermore, the energy consumed per unit of cooling / dehumidification changes dynamically with temperature and humidity. Furthermore, the theoretical data from enthalpy difference experiments is disconnected from reality, and errors may exist between the data and actual applications, ultimately resulting in low accuracy in the energy consumption measurements.

[0066] To make the above-mentioned purposes, features, and advantages of the present application more clearly understood, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection of this application.

[0067] When using air conditioning equipment (such as air conditioners), it's often necessary to quantify the power consumption associated with temperature and humidity changes. This allows for determining the sensible heat / latent heat ratio of the air conditioner under various conditions, thereby estimating its energy consumption. Current methods for calculating the sensible heat / latent heat ratio primarily calculate the energy consumption associated with temperature and humidity changes per unit time, and then calculate the ratio between these values ​​and the total energy consumption.

[0068] However, existing energy consumption acquisition technologies have several drawbacks. First, energy consumption calculations rely on multiple instruments, such as enthalpy difference experiments, which places high demands on the equipment and hinders widespread application. Furthermore, as temperature and humidity fluctuate, the energy consumed per unit of cooling / dehumidification also changes dynamically, resulting in low accuracy in the energy consumption obtained. Therefore, there is an urgent need for an energy consumption acquisition method that can quantitatively detect temperature and humidity energy consumption changes and facilitate accurate calculation of sensible and latent heat.

[0069] Based on this, the present application proposes a method for obtaining energy consumption of an air conditioning device according to a first embodiment, referring to FIG1 . The method for obtaining energy consumption of an air conditioning device includes:

[0070] Step S10, obtaining the temperature change and humidity change corresponding to the current cycle and the previous cycle respectively;

[0071] In some embodiments, when obtaining energy consumption for air conditioning equipment, the equipment's operating time can be divided into multiple cycles, and the temperature change and humidity change can be obtained for each cycle. This allows the temperature and humidity changes to be relatively small between adjacent cycles, resulting in no significant change in the temperature and humidity control power. Therefore, based on the temperature change, humidity change, and energy consumption between two adjacent cycles, the temperature change energy consumption and humidity change energy consumption for the current cycle can be determined, thereby calculating the corresponding sensible heat ratio and latent heat ratio.

[0072] It should be noted that the shorter the cycle duration is, the more accurate the calculated energy consumption will be, while the longer the cycle duration is, the less accurate the energy consumption will be. However, if the cycle duration is set too short, the calculation will be more complex and require more computing resources. Therefore, users can set an appropriate cycle duration (such as 30s) according to their needs.

[0073] Specifically, in the previous cycle and the current cycle, the temperature change and the humidity change in the environment can be read by the temperature sensor and the humidity sensor.

[0074] In some embodiments, the temperature change value generated by the current cycle is calculated as Δt(i)=t(i)-t(i-1), where Δt(i) is the temperature change of the current cycle, t(i) is the temperature value at the end time of the current cycle, and t(i-1) is the temperature value at the start time of the current cycle; the humidity change value generated by the current cycle is calculated as Δh(i)=h(i)-h(i-1), where Δh(i) is the humidity change of the current cycle, h(i) is the humidity value at the end time of the current cycle, and h(i-1) is the humidity value at the start time of the current cycle. It can be understood that in the previous cycle, the temperature change is Δt(i-1) and the humidity change is Δh(i-1).

[0075] Step S20, obtaining the energy consumption generated in the current cycle and the energy consumption generated in the previous cycle;

[0076] In some embodiments, taking cooling and dehumidification as an example, the indoor temperature is cooled and dehumidified by air conditioning equipment, and the energy consumption (power consumption) generated in the current cycle and the previous cycle is obtained according to the electricity meter or power / energy consumption prediction model. It should be noted that the energy consumption is the energy consumption generated by cooling and dehumidification.

[0077] In some embodiments, the power consumption generated in the current cycle is E(i), and the power consumption generated in the previous cycle is E(i-1).

[0078] Step S30, based on the temperature change, humidity change, energy consumption of the current cycle and energy consumption of the previous cycle, calculate the energy consumption caused by the temperature change in the current cycle and the energy consumption caused by the humidity change in the current cycle.

[0079] Specifically, after obtaining the temperature change, humidity change, energy consumption of the current cycle and energy consumption of the previous cycle in the current cycle and the previous cycle, 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, the cooling power x and the dehumidification power can be considered to be constant, and in two adjacent cycles, the following adjustments are satisfied respectively: the cooling power is multiplied by the temperature change to obtain the cooling power consumption, and the dehumidification power is multiplied by the humidity change to obtain 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 and humidity change respectively to obtain the cooling power consumption and dehumidification power consumption of the current cycle.

[0080] After obtaining the cooling and dehumidification power consumption for the current cycle, the sensible heat ratio and latent heat ratio can be calculated. The sensible heat ratio is the ratio of cooling power consumption to total energy consumption, while the latent heat ratio is the ratio of dehumidification power consumption to total energy consumption. Calculating the sensible and latent heat ratios provides a robust data foundation for subsequent air conditioning equipment energy-saving control, comfort, and building model design.

[0081] In some embodiments, the energy consumption caused by the temperature change in the current cycle and the energy consumption caused by the humidity change in the current cycle can be calculated based on the temperature change, humidity change, energy consumption in the current cycle, and energy consumption in the previous cycle because the following equation is satisfied in any cycle:

[0082] Unit cooling power consumption x*cooling amplitude Δt=cooling power consumption Et;

[0083] Unit dehumidification power consumption y*dehumidification amplitude Δh=dehumidification power consumption Eh;

[0084] Cooling power consumption Et + dehumidification power consumption Eh = total power consumption E.

[0085] It's understandable that the above equations hold true within a single cycle. However, referring to the statistical diagram of temperature and humidity changes over time shown in Figure 2, when air conditioning equipment operates at constant power, the energy consumed per unit of cooling / dehumidification will also change dynamically as temperature and humidity change. In other words, x and y will change dynamically. Therefore, the above formula only applies to short cycles. The cycle in Figure 2 is merely an example and does not impose any limitations on the technical solutions of the embodiments of this application.

[0086] 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 → +∞, integration can be used to calculate the latent heat and sensible heat energy consumption.

[0087] For example, for a fixed period T, if T→+0, that is, the number of periods→+∞, then:

[0088] Therefore, in practical applications, a smaller cycle length can be used to approximately calculate x and y for each cycle to obtain the unit cooling power consumption x and unit dehumidification power consumption y in each short cycle.

[0089] This application obtains the temperature change, humidity change, energy consumption, etc. of the current cycle and the previous cycle on a cycle basis to calculate the energy consumption generated by the temperature change and the energy consumption generated by the humidity change in the current cycle. It realizes the perception and calculation of temperature and humidity energy consumption through a quantitative method, and does not require enthalpy difference experimental equipment to calculate and obtain energy consumption. It can be widely applied to a wider range of usage scenarios. Moreover, this application only calculates the energy consumption corresponding to the temperature change and humidity change of the current cycle through the temperature and humidity change and energy consumption of two adjacent cycles. Since the temperature and humidity difference between adjacent cycles is small, it overcomes the technical defect that when the temperature and humidity are at different values, the energy consumed per unit cooling / dehumidification is different, thereby affecting the accuracy of energy consumption. Moreover, since the enthalpy difference experiment is completed in the laboratory, the actual operating conditions are not taken into account. The present application adopts a calculation method that is out of the laboratory and based on the actual operating conditions. The energy consumption obtained is more accurate, thereby solving the technical problem of low accuracy in obtaining the energy consumption of temperature change and humidity change per unit time using enthalpy difference experimental equipment in the existing technology.

[0090] In some embodiments, the step of calculating the energy consumption caused by the temperature change in the current cycle and the energy consumption caused by the humidity change in the current cycle based on the temperature change, humidity change, energy consumption in the current cycle, and energy consumption in the previous cycle includes:

[0091] Step S31, calculating a first unit energy consumption generated by a unit temperature change and a second unit energy consumption generated by a unit humidity change based on the temperature change and humidity change of the current cycle and the previous cycle, the energy consumption of the current cycle and the energy consumption of the previous cycle;

[0092] In some embodiments, it should be noted that the first unit energy consumption refers to the energy (electrical energy) required to reduce the temperature by 1°C when cooling the environment, and the second unit energy consumption refers to the energy required to reduce the humidity by 1% when dehumidifying the environment. Because the first unit energy consumption and the second unit energy consumption can be approximately considered unchanged between the previous cycle and the current cycle, the first unit energy consumption and the second unit energy consumption can be calculated based on the temperature change and humidity change between the previous cycle and the current cycle, the energy consumption of the current cycle, and the energy consumption of the previous cycle to calculate the energy consumed for cooling and the energy consumed for dehumidification in the current cycle.

[0093] Step S32, calculating the energy consumption caused by the temperature change in the current cycle based on the temperature change in the current cycle and the first unit energy consumption;

[0094] Step S33: Calculate the energy consumption caused by the humidity change in the current cycle according to the humidity change in the current cycle and the second unit energy consumption.

[0095] It can be understood that after the first unit energy consumption x(i) and the second unit energy consumption y(i) are calculated, the cooling power consumption in the current cycle Et(i) = E(i)*T*x(i) / (x(i)+y(i)) and the dehumidification power consumption in the current cycle Eh(i) = E(i)*T*y(i) / (x(i)+y(i)) can be calculated respectively, where Et(i) is the cooling power consumption, that is, the energy consumption caused by the temperature change in the current cycle, E(i) is the total energy consumption of the current cycle, T is the cycle length, 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 caused by the humidity change in the current cycle.

[0096] Furthermore, after obtaining the cooling power consumption and dehumidification power consumption of the current cycle, the sensible heat ratio and latent heat ratio of the current cycle can be calculated, where the sensible heat ratio = Et(i) / (Et(i)+Eh(i)); the latent heat ratio = Eh(i) / (Et(i)+Eh(i)).

[0097] In some embodiments, the step of calculating the first unit energy consumption generated by a unit temperature change and the second unit energy consumption generated by a unit humidity change based on the temperature change, humidity change, energy consumption of the current cycle, and energy consumption of the previous cycle in the current cycle includes:

[0098] Step S311, constructing a first relationship based on the temperature change, humidity change, and energy consumption of the current cycle;

[0099] 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.

[0100] In some embodiments, the first relationship is: Δt(i)*x(i)+Δh(i)*y(i)=E(i), where 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.

[0101] Step S312, constructing a second relationship based on the humidity change amount, the humidity change amount, and the energy consumption of the previous cycle;

[0102] 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 of the previous cycle in the previous cycle.

[0103] In some embodiments, the second relationship is: Δt(i-1)*x(i)+Δh(i-1)*y(i)=E(i-1), where 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.

[0104] In step S313 , a first unit energy consumption generated by a unit temperature change and a second unit energy consumption generated by a unit humidity change are calculated based on the first relationship and the second relationship.

[0105] In some embodiments, after constructing the first and second relationship equations, the first and second relationship equations can be combined and solved as a set of two linear equations to obtain the unknowns in the set of equations, namely the first unit energy consumption and the second unit energy consumption of the current cycle.

[0106] In some embodiments, 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:

[0107] 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 based on the energy consumption caused by temperature changes in the historical period and the energy consumption caused by humidity changes in the historical period;

[0108] In some embodiments, the energy consumption generated by temperature changes and the energy consumption generated by humidity changes in each cycle are calculated according to the method of steps S10 to S20, and the sums are added respectively 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.

[0109] Step S40 , calculating the total energy consumption during the operation of the air conditioning equipment according to 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.

[0110] 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 caused by temperature changes and the total energy consumption caused 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 electric meter module or a power / energy consumption prediction model, thereby calculating the total power consumption E=∑E(i).

[0111] Furthermore, after obtaining 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, the method may further include:

[0112] Step S50 , displaying the total energy consumption during the operation of the air conditioning equipment, the total energy consumption caused by temperature changes, and the total energy consumption caused by humidity changes.

[0113] The total power consumption for cooling E = ∑Et(i), the total power consumption for dehumidification E = ∑Eh(i), and the total power consumption E = ∑E(i) are obtained and displayed to the user in a visual manner, so that the user can clearly see how much electricity is used for cooling, how much electricity is used for dehumidification, and how much total energy is consumed during the operation of the air conditioning equipment.

[0114] Furthermore, based on determining the total energy consumption during the operation of the air conditioning equipment, the total energy consumption caused by temperature changes, and the total energy consumption caused by humidity changes, the sensible heat ratio and latent heat ratio of the air conditioning equipment from startup to the current cycle can be calculated.

[0115] In some embodiments, from power-on to the current cycle, the sensible heat ratio of this operation is calculated as ∑Et(i) / (∑Et(i)+∑Eh(i)); from power-on to the current cycle, the latent heat ratio of this operation is calculated as ∑Eh(i) / (∑Et(i)+∑Eh(i)).

[0116] 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 energy consumption acquisition method of the air conditioning equipment of the present application. More simple transformations based on this technical concept are all within the scope of protection of the present application.

[0117] In another embodiment of the present application, the same or similar contents as those in the above embodiment can be referred to the above description and will not be described in detail. On this basis, please refer to FIG3 , the present application also provides a control method for an air conditioning device, the control method for an air conditioning device comprising:

[0118] Step A10, obtaining the temperature-humidity energy consumption ratio of the current cycle;

[0119] Referring to the method for calculating the energy consumption caused by temperature changes and humidity changes in the current cycle in the previous embodiment, the temperature-humidity energy consumption ratio of the current cycle is calculated, where the temperature-humidity energy consumption ratio can be a sensible heat ratio or a latent heat ratio. The sensible heat ratio is equal to the ratio of the energy consumption caused by temperature changes to the total energy consumption, and the latent heat ratio is equal to the ratio of the energy consumption caused by humidity changes to the total energy consumption.

[0120] In some embodiments, the sensible heat ratio may be used as an example to measure the current energy-saving state of the air conditioning equipment, thereby determining the control mode of the air conditioning equipment and adjusting the energy-saving state of the air conditioning equipment.

[0121] Step A20, calculating a first average temperature-humidity energy consumption ratio of all cycles of the air conditioning equipment;

[0122] In some embodiments, the first average temperature and humidity energy consumption ratio is the temperature and humidity energy consumption ratio of the air conditioning equipment from the first cycle after startup to the current cycle, which can be obtained by calculating the ratio between the total energy consumption of all temperature changes (or the total energy consumption of humidity changes) and the total energy consumption since startup. Taking the temperature and humidity energy consumption ratio as the sensible heat ratio as an example, the first average temperature and humidity energy consumption ratio can be understood as the global average sensible heat ratio from the first cycle to the current cycle.

[0123] Step A30, calculating the second average temperature-humidity energy consumption ratio of the air conditioning equipment in the current cycle and the previous multiple historical cycles;

[0124] In some embodiments, the second average temperature and humidity energy consumption ratio is the average sensible heat ratio of a preset number of cycles from the current cycle, which can be obtained by calculating the ratio between the total energy consumption of temperature changes (or the total energy consumption of humidity changes) for a preset number of cycles from the current cycle and the energy consumption within the preset number of cycles. It can be understood as the average sensible heat ratio of the recent preset number of cycles.

[0125] Step A40: determining a control mode of the air conditioning equipment 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 equipment to operate according to the determined control mode.

[0126] It should be noted that the first average temperature-humidity energy consumption ratio and the second average temperature-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 to achieve the adjustment of the energy-saving state of the air-conditioning equipment, so that the air-conditioning equipment always operates in the best energy-saving state, taking into account the energy saving and comfort of the air-conditioning equipment, realizing energy-saving control of sensible heat and latent heat, and improving the intelligence level of the air-conditioning equipment and user experience.

[0127] In some embodiments, the value of the sensible heat ratio can be used to characterize the energy-saving status of air conditioning equipment (such as air conditioning), 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).

[0128] In some embodiments, the step of determining a control mode of the air conditioning equipment based on 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 equipment to operate according to the determined control mode includes:

[0129] Step A41: When the difference between the first average temperature-humidity energy consumption ratio and the target temperature-humidity energy consumption ratio is within a first preset range, the current operation mode of the air conditioning equipment is maintained and the operation continues.

[0130] It can be understood that the target temperature and humidity energy consumption ratio is the temperature and humidity energy consumption ratio that enables the air conditioning equipment to 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 determined that the current air conditioning equipment is in a more appropriate energy-saving state and no adjustment is required.

[0131] In some embodiments, the first preset range may be (-0.1, +0.1).

[0132] In some embodiments, the step of determining a control mode of the air conditioning equipment based on 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 equipment to operate according to the determined control mode includes:

[0133] 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, determining 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;

[0134] In some embodiments, taking the temperature and humidity energy consumption ratio as the sensible heat 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 last preset number of cycles to determine whether it is necessary to adjust the energy-saving state and control mode of the air conditioning equipment.

[0135] In some embodiments, the first preset threshold is -0.1.

[0136] Step A43: When the difference between the second average temperature-humidity energy consumption ratio and the target temperature-humidity energy consumption ratio is greater than or equal to the second preset threshold, the current operation mode of the air conditioning equipment is maintained and the operation continues;

[0137] In some embodiments, taking the temperature and humidity energy consumption ratio as the sensible heat 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, in the near future, 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 a medium energy-saving state, maintain good comfort and energy-saving effects, and ensure the user experience.

[0138] In some embodiments, the second preset threshold is 0.1.

[0139] Step A44: 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, the operating frequency and fan speed of the air conditioning equipment are adjusted according to a preset ratio.

[0140] In some embodiments, taking the temperature and humidity energy consumption ratio as the sensible heat 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 equal to the second preset threshold, this indicates that the air conditioning equipment is in a weak energy-saving state from a global perspective, but in the near future, the air conditioning equipment is in a medium energy-saving or weak energy-saving state, so if the current operating mode continues, the air equipment will continue to be in a weak energy-saving state from a global perspective. 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, so that the air conditioning equipment will tend to a medium energy-saving state, maintain good comfort and energy-saving effects, and ensure the user experience.

[0141] It should be noted that when the sensible heat ratio needs to be increased (or the latent heat ratio needs to be reduced), the wind speed needs to be increased and the operating frequency needs to be reduced. The preset ratio can be set according to user needs to achieve the control effect of increasing wind speed and reducing frequency.

[0142] Furthermore, in some embodiments, 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, the step of adjusting the operating frequency and fan speed of the air conditioning equipment according to a preset ratio includes:

[0143] Step A441: When the temperature-humidity energy consumption ratio is the ratio of energy consumption caused by temperature change to total energy consumption, the operating frequency is reduced according to a first preset ratio, and the fan speed is increased according to a second preset ratio;

[0144] In some embodiments, a method for adjusting the operating frequency and fan speed of air-conditioning equipment when the temperature-humidity energy consumption ratio is the sensible heat ratio (the ratio of energy consumption caused by temperature changes to total energy consumption) is disclosed. That is, it is necessary to increase the sensible heat ratio to improve the energy-saving effect, and then reduce the operating frequency according to a first preset ratio, and increase the fan speed according to a second preset ratio, thereby improving the sensible heat ratio and improving the energy-saving effect.

[0145] Step A442: When the temperature-humidity energy consumption ratio is the ratio of the energy consumption caused by humidity change to the total energy consumption, the operating frequency is increased according to a first preset ratio, and the fan speed is reduced according to a second preset ratio.

[0146] In some embodiments, a method for adjusting the operating frequency and fan speed of an air-conditioning device when the temperature-humidity energy consumption ratio is a latent heat ratio (the ratio of energy consumption caused by humidity changes to total energy consumption) is disclosed. Because the sum of the sensible heat ratio and the latent heat ratio is always 1, when the sensible heat ratio increases, the latent heat ratio decreases, 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 means that the sensible heat ratio of the current air-conditioning device is too high and is in a strong energy-saving mode. The energy-saving effect needs to be reduced to take into account comfort. Therefore, the sensible heat ratio needs to be reduced at this time. In contrast to step A441, in this step, the operating frequency needs to be increased according to the first preset ratio, and the fan speed needs to be reduced according to the second preset ratio, thereby increasing the latent heat ratio, reducing the sensible heat ratio, and reducing the energy-saving effect.

[0147] In some embodiments, the step of determining a control mode of the air conditioning equipment based on 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 equipment to operate according to the determined control mode includes:

[0148] Step A45: When the difference between the first average temperature and humidity energy consumption ratio and the target temperature and humidity energy consumption ratio is greater than or equal to the third preset threshold, determine whether 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 equal to the fourth preset threshold;

[0149] In some embodiments, taking the temperature and humidity energy consumption ratio as the sensible heat 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 greater than or equal to the third 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 greater than the target temperature and 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 and humidity energy consumption ratio of the air conditioning equipment in the last preset number of cycles to determine whether it is necessary to adjust the control mode and energy-saving state of the air conditioning equipment.

[0150] In some embodiments, the third preset threshold is 0.1.

[0151] 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 a fourth preset threshold, the current operation mode of the air conditioning device is maintained and the operation continues;

[0152] In some embodiments, taking the temperature and humidity energy consumption ratio as the sensible heat 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 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, in the near future, the air-conditioning equipment is in a weak energy-saving state. Therefore, as long as the current operating 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, maintain good comfort and energy-saving effects, and ensure the user experience.

[0153] In some embodiments, the fourth preset threshold is -0.1.

[0154] 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 a fourth preset threshold, the operating frequency and fan speed of the air conditioning equipment are adjusted according to a preset ratio.

[0155] In some embodiments, taking the temperature and humidity energy consumption ratio as the sensible heat 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 the fourth preset threshold, this indicates that the air conditioning equipment is in a strong energy-saving state from a global perspective, but in the near future, the air conditioning equipment is in a medium energy-saving or strong energy-saving state, so if the current operating mode continues, the global perspective of the air equipment will continue to be in a strong energy-saving state, and 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, so that the air conditioning equipment will eventually tend to a medium energy-saving state, maintain good comfort and energy-saving effects, and ensure the user experience.

[0156] Furthermore, in some embodiments, when the difference between the second average temperature-humidity-energy consumption ratio and the target temperature-humidity-energy consumption ratio is greater than a fourth preset threshold, the step of adjusting the operating frequency and fan speed of the air conditioning equipment according to a preset ratio includes:

[0157] Step A471: When the temperature-humidity energy consumption ratio is the ratio of energy consumption caused by temperature change to total energy consumption, the operating frequency is increased according to a first preset ratio, and the fan speed is reduced according to a second preset ratio;

[0158] In some embodiments, a method for adjusting the operating frequency and fan speed of an air-conditioning device when the temperature-humidity energy consumption ratio is the sensible heat ratio (the ratio of the energy consumption caused by temperature changes to the total energy consumption) is disclosed. That is, it is necessary to lower the sensible heat ratio to reduce the energy-saving effect, and then increase the operating frequency according to a first preset ratio, and reduce the fan speed according to a second preset ratio, thereby reducing the sensible heat ratio and reducing the energy-saving effect.

[0159] Step A472: When the temperature-humidity energy consumption ratio is the ratio of the energy consumption caused by humidity change to the total energy consumption, the operating frequency is reduced according to the first preset ratio, and the fan speed is increased according to the second preset ratio.

[0160] In some embodiments, a method for adjusting the operating frequency and fan speed of an air-conditioning device when the temperature-humidity energy consumption ratio is a latent heat ratio (the ratio of energy consumption caused by humidity changes to total energy consumption) is disclosed. Because the sum of the sensible heat ratio and the latent heat ratio is always 1, when the sensible heat ratio increases, the latent heat ratio decreases, 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 means that the sensible heat ratio of the current air-conditioning device is too low and is in a weak energy-saving mode, and the energy-saving effect needs to be improved. Therefore, the sensible heat ratio needs to be increased at this time. In contrast to step A471, in this step, the operating frequency needs to be reduced according to the first preset ratio, and the fan speed needs to be increased according to the second preset ratio, thereby reducing the latent heat ratio, improving the sensible heat ratio and improving the energy-saving effect.

[0161] In a feasible embodiment, taking the temperature-humidity energy consumption ratio as the sensible heat ratio as an example, assuming that the target temperature-humidity energy consumption ratio is 0.8, first obtain the sensible heat ratio Q(i) of the current cycle, then calculate the global average sensible heat ratio Qt(i) from cycle 1 to cycle i, then calculate the average sensible heat ratio Qn(i) of the past N cycles from cycle (i-N+1) to cycle i, 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 values ​​of Qt(i)-0.8 and Qn(i)-0.8 and Table 1 below, wherein the energy-saving state may include under-energy-saving, normal energy-saving and over-energy-saving, or referred to as weak energy-saving, medium energy-saving and strong energy-saving.

[0162] Table 1

[0163] Among them, the strategy for reducing energy saving is to reduce the wind speed and increase the frequency according to a specific ratio (reduce the sensible heat ratio and increase the latent heat ratio); while the strategy for improving energy saving is to increase the wind speed and reduce the frequency according to a specific ratio (increase the sensible heat ratio and reduce the latent heat ratio).

[0164] Furthermore, the specific steps of the control method of the air conditioning equipment of the present application are shown in Figure 4. First, the air conditioner is turned on, and the current energy-saving mode and the corresponding sensible heat ratio are obtained. Every time T (30s), the following logic (cycle i) is executed: the sensible heat ratio Q(i) of the current cycle is obtained, the average sensible heat ratio Qt(i) from the 1-i cycle is calculated, and the average sensible heat ratio Qn(i) from the (i-N+1)-i cycle is calculated; the size relationship between Qn(i)-0.8, Qt(i)-0.8 and 0.1 is determined, and the energy-saving improvement / maintenance / reduction strategy is executed according to the two-dimensional segmentation.

[0165] In some embodiments, the step of obtaining the temperature-humidity energy consumption ratio of the current cycle includes:

[0166] Step A11, obtaining the temperature change and humidity change corresponding to the current cycle and the previous cycle respectively;

[0167] Step A12, obtaining the energy consumption generated in the current cycle and the energy consumption generated in the previous cycle;

[0168] Step A13, calculating the energy consumption caused by the temperature change in the current cycle and the energy consumption caused by the humidity change in the current cycle based on the temperature change and humidity change in the current cycle and the previous cycle, the energy consumption in the current cycle and the previous cycle;

[0169] Step A14: Calculate the temperature-humidity energy consumption ratio of the current cycle based on the energy consumption generated by the temperature change of the current cycle and the energy consumption generated by the humidity change of the current cycle.

[0170] In some embodiments, 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 repeated 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, based on 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.

[0171] In some embodiments, from power-on to the current cycle, the sensible heat ratio of this operation is calculated as ∑Et(i) / (∑Et(i)+∑Eh(i)); from power-on to the current cycle, the latent heat ratio of this operation is calculated as ∑Eh(i) / (∑Et(i)+∑Eh(i)).

[0172] This application implements 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, so that the air conditioning equipment is in the best operating state as much as possible, avoiding excessive energy consumption or excessive energy saving that affects comfort, achieving long-term stable / short-term flexible energy-saving control, and improving the user experience.
