Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and particularly to a method and device for determining a temperature curve and an air conditioning device. Background Art

[0002] Currently, the energy-saving method for household air conditioners is to set an energy-saving button on the air conditioner remote control, and the logic of the energy-saving button is generally to simply set the temperature of the air conditioning device to 26 degrees.

[0003] However, due to different regions, different climate conditions, uneven indoor temperatures in different room layouts, and different individual heat adaptation situations, etc., the simple energy-saving condition of 26 degrees may not bring real energy savings. Moreover, sometimes energy savings will sacrifice user comfort and violate the essence of the air conditioner. For example, when the heat load of a user's family is small, simply setting the air conditioner temperature to 26°C will cause the indoor temperature to be too low, resulting in energy waste and a decrease in user comfort; when the heat load of a user's family is large, when setting the air conditioner temperature to 26°C, the air conditioner may not reach the set temperature for a long time, unable to meet the user's cooling requirement, resulting in a decrease in comfort.

[0042] In the description, claims and the above drawings of the present invention, the terms "first", "second", "third", "fourth", etc. (if any) are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances so that the embodiments described herein can be implemented in an order different from that shown or described herein. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device comprising a series of steps or units need not be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices. 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 of the embodiments.

[0043] In combination with Figure 1 Shown in the flowchart, a method for determining a temperature curve provided by an embodiment of the present invention includes steps 101 to 103:

[0044] Step 101: In response to the target set temperature of the next target period input by the user, obtain the target environmental parameters of the next target period and the first total energy consumption of the current target period. The target environmental parameters include the target collection time and the target outdoor temperature corresponding to the target collection time.

[0045] In this embodiment, the target period refers to a cycle time when the air conditioning device operates according to the temperature curve set by the user when it is turned on. The target period can be 3 days, 5 days or one week. In this embodiment, one week is used as the target period for illustration. The current target period refers to the target period in which the user is currently located, and the next target period refers to a future target period. Generally, the next target period refers to a future target period adjacent to the current target period.

[0046] When the current target period has passed or is about to pass, the user can set the temperature curve for the next target period. When setting the temperature curve, mainly the target set temperature is set. For example, on Sunday night, the user sets the target set temperature of the next target period to 24 degrees through a mobile terminal associated with the air conditioning device. Then, during the next target period, the set temperature after the air conditioning device is turned on is 24 degrees. Among them, the mobile terminal can be a device such as a mobile phone or a tablet.

[0047] It should be noted that in the next target period, the user's target set temperature can be a fixed value or set in time segments. For example, in the next target period, the user sets the air conditioning equipment to turn on from 9 pm to 7 am the next day, and the target set temperature when it turns on is 26 degrees; the air conditioning equipment is turned on from 5 pm to 9 pm every day, and the target set temperature when it turns on is 24 degrees. In addition, the user can set different target set temperatures for different rooms or different functional areas.

[0048] After the user inputs the target set temperature for the next target period, the air conditioning equipment will respond to the target set temperature input by the user and then obtain the target environmental parameters for the next target period and the first total energy consumption for the current target period. The first total energy consumption for the current target period refers to the electricity consumed by using the air conditioning equipment during the current target period.

[0049] Among them, the target environmental parameters refer to the parameters collected when the air conditioning equipment operates, mainly including the target collection time and the target outdoor temperature corresponding to the target collection time. The target environmental parameters are used to estimate the energy consumption for the next target period. In this embodiment, the target collection time refers to the time when the sensor collects the outdoor temperature each time. Generally, the data in this embodiment is collected hourly. That is to say, when the air conditioning equipment is running, data is collected once every whole hour, and the time of the collected data is recorded.

[0050] It is not difficult to understand that since the next target period has not occurred yet, the method for obtaining the target outdoor temperature for the next target period can refer to the following 3 implementation methods:

[0051] In Implementation Method 1, the outdoor temperature for the next target period can be obtained through the weather information for the next target period.

[0052] In Implementation Method 2, first, it is necessary to determine the season in which the next target period is located. If the next target period is in a hot or cold season, it means that the previous and next two weeks are also within the range of stable climate. Therefore, the outdoor temperature for the current target period can be used as the target outdoor temperature for the next target period. If the next target period is in a transitional season, the outdoor temperature for the current target period is corrected, and the corrected outdoor temperature for the current target period is used as the target outdoor temperature for the next target period. For example, the target outdoor temperature for the current target period is corrected according to the following formula to replace the target outdoor temperature for the next target period. The correction formula is:

[0053] T 1 =T 0 +ΔT 1

[0054] Among them, T 1is the target outdoor temperature for the next target period; T 0 is the outdoor temperature for the current target period; ΔT 1 is the weather change adjustment value. The determination of the weather change adjustment value can be made by analyzing the temperature change trend in the corresponding season in the historical climate database of previous years, and then making a reasonable selection. For example, if the average temperature in the corresponding cold transition season of previous years decreased by 1 degree, the weather change adjustment value can be selected as -1 degree for reference.

[0055] In Embodiment 3, after performing correction processing based on the outdoor temperature at the corresponding time in the historical climate database of previous years, it can be used to replace the target outdoor temperature for the next target period. The correction formula is:

[0056] T this_year = T last_year + ΔT 2

[0057] where, T this_year is the target outdoor temperature for the next target period; T last_year is the outdoor temperature in the same period of previous years; ΔT 2 is the climate change adjustment value.

[0058] Among them, the climate change adjustment value can be reasonably selected after analyzing the climate change trend through the historical climate database of previous years. For example, if the annual average temperature has risen by 0.3 degrees due to the impact of climate warming in the past years, the climate change adjustment value can be selected as +0.3 degrees for reference.

[0059] It should be noted that the above three embodiments each have their own advantages. In the actual use process, any one of the three embodiments can be selected according to specific conditions, or a new embodiment can be formed by referring to the above three embodiments to obtain the target outdoor temperature for the next target period. This embodiment does not make any limitations in this regard.

[0060] Step 102: According to the target environmental parameters and the target set temperature, calculate the second total energy consumption for the next target period through a preset fitting energy consumption formula;

[0061] In this embodiment, the fitting energy consumption formula is used to estimate the energy consumption after the air conditioning equipment is turned on in the next target period. The fitting energy consumption formula is obtained by fitting based on historical environmental parameters. As shown in Figure 2 , the steps for determining the fitting energy consumption formula may include steps 201 - 203:

[0062] Step 201: Determine the season cycle in which the next target period is located;

[0063] Step 202: Obtain the historical collection time of the historical seasonal cycle synchronous with the said seasonal cycle, as well as the corresponding historical indoor temperature and historical outdoor temperature at the said historical collection time;

[0064] Step 203: Obtain a fitted energy consumption formula based on the said historical collection time, as well as the corresponding historical indoor temperature and historical outdoor temperature at the said historical collection time.

[0065] It should be noted that since the fitted energy consumption formula is obtained by fitting based on historical environmental parameters, it is slightly different due to the influence of different seasons.

[0066] Based on this, in this embodiment, it will be determined which seasonal cycle the next target cycle is in according to the time of the next target cycle. For example, if the next target cycle is from August 1st to 7th, it is determined that the next target cycle is in the summer cycle. Then obtain the usage data of all air-conditioning equipment in this area during the summer cycle in the past 3 years. The usage data refers to the historical collection time, as well as the corresponding historical indoor temperature and historical outdoor temperature at the historical collection time. Then, based on the obtained historical collection times, as well as the corresponding historical indoor temperature and historical outdoor temperature at the historical collection time, obtain a fitted energy consumption formula. Of course, if the user's air-conditioning equipment has been used for a period of time (for example, the air-conditioning equipment has been used for 2 years), then the usage data of the user's own air-conditioning equipment during the summer cycle in the past 2 years can also be obtained. The usage data refers to the historical collection time, as well as the corresponding historical indoor temperature and historical outdoor temperature at the historical collection time. Then, based on the obtained historical collection times, as well as the corresponding historical indoor temperature and historical outdoor temperature at the historical collection time, obtain a fitted energy consumption formula.

[0067] After determining the fitted energy consumption formula, the second total energy consumption of the next target cycle can be calculated according to the target environmental parameters and the target set temperature. The second total energy consumption refers to the estimated power consumption required to turn on the air-conditioning equipment in the next target cycle.

[0068] In an alternative embodiment, the step of calculating the second total energy consumption of the next target cycle according to the target environmental parameters and the target set temperature through a preset fitted energy consumption formula may include:

[0069] For each target collection time, determine the absolute value of the temperature difference corresponding to the target collection time according to the target outdoor temperature and the target set temperature corresponding to the target collection time;

[0070] According to each target collection time, as well as the absolute value of the temperature difference corresponding to the target collection time, calculate the second total energy consumption of the next target cycle through a preset fitted energy consumption formula.

[0071] Among them, the target acquisition time refers to the time when the outdoor temperature of the target is acquired when the air-conditioning equipment is turned on. Generally, it is set at the whole hour, which is convenient for recording and calculation. The target outdoor temperature is obtained at each target acquisition time, and the acquisition method refers to the foregoing content.

[0072] It should be noted that after the air-conditioning equipment is turned on for a period of time, the indoor temperature will gradually reach the target set temperature. Therefore, when estimating the second total energy consumption in the next target cycle, in this embodiment, the target set temperature is used as the indoor temperature and substituted into the fitting energy consumption formula for calculation. At each target acquisition time, the absolute value of the temperature difference is calculated based on the target set temperature and the target outdoor temperature. It is not difficult to understand that the absolute value of the temperature difference refers to the absolute value of the difference between the target outdoor temperature and the target set temperature. Then, each target acquisition time and the absolute value of the temperature difference corresponding to this target acquisition time are respectively substituted into the preset fitting energy consumption formula. In an optional implementation manner, the fitting energy consumption formula is:

[0073] HCL = A·H 2 + B·H + C·Δt 2 + D·Δt + E

[0074] Among them, HCL represents the energy consumption of the air-conditioning equipment between this target acquisition time and the previous adjacent target acquisition time; H is the target acquisition time; Δt is the absolute value of the temperature difference corresponding to this target acquisition time; A, B, C, D, and E are difference coefficients.

[0075] It should be noted that the energy consumption of the air-conditioning equipment within two adjacent acquisition times calculated by substituting into the above fitting energy consumption formula is obtained. Finally, it is also necessary to accumulate the energy consumption of the air-conditioning equipment within all the above calculated adjacent two acquisition times, and the final result obtained is the second total energy consumption.

[0076] Step 103: Calculate the energy-saving rate of the next target cycle relative to the current target cycle according to the first total energy consumption and the second total energy consumption, and display it to the user.

[0077] In this embodiment, after obtaining the first total energy consumption and the second total energy consumption, the energy-saving rate of the next target cycle relative to the current target cycle can be calculated according to the first total energy consumption and the second total energy consumption. Specifically, the energy consumption difference can be obtained by subtracting the second total energy consumption of the next target cycle from the first total energy consumption of the current target cycle, and then dividing the energy consumption difference by the first total energy consumption, the energy-saving rate of the next target cycle relative to the current target cycle can be obtained, and then the calculated energy-saving rate is displayed to the user. In addition, the unit average energy consumption per hour can also be calculated according to the estimated second total energy consumption, and then compared with the unit average energy consumption of all users in the same historical period in the area where the user is located, and the percentage of the user's current unit average energy consumption ranking is calculated to display the usage situation of the user among the general consumers.

[0078] It should be noted that if the air conditioning equipment is operated according to the time zone corresponding to the set temperature of the current target period within the current target period, when calculating the energy saving rate, directly subtract the second total energy consumption from the first total energy consumption to obtain the energy consumption difference, and then divide the energy consumption difference by the first total energy consumption to obtain the energy saving rate of the next target period relative to the current target period.

[0079] If the air conditioning equipment is not completely operated according to the time zone corresponding to the set temperature of the current target period within the current target period, when calculating the energy saving rate, it is necessary to process the usage time of the air conditioning equipment. That is, compare the usage time of the air conditioning equipment in the next target period with the usage time of the air conditioning equipment in the current target period, accumulate the energy consumption of the air conditioning equipment in the overlapping time zones to obtain the new first total energy consumption and the new second total energy consumption respectively, then subtract the new second total energy consumption from the new first total energy consumption to obtain the energy consumption difference, and then divide the energy consumption difference by the new first total energy consumption to obtain the energy saving rate of the next target period relative to the current target period.

[0080] The calculated energy saving rate is used to display to the user so that the user can intuitively view the energy consumption based on the current target set temperature, thereby guiding the user to more reasonably adjust the temperature curve according to individual preferences under the condition of meeting comfort, so as to achieve the effects of energy saving and environmental protection.

[0081] In this embodiment, the energy saving rate can guide users to save energy and protect the environment, but at the same time, the real comfort of users needs to be considered. Most users simply think that 25 degrees or 26 degrees is the most comfortable temperature. However, the optimal comfort temperature varies in different seasons and regions.

[0082] Therefore, this embodiment will also display the comfort temperature difference value to the user so that the user can understand the gap between the target set temperature and the optimal comfort temperature in the region and season where the user is located in the next target period, thereby further balancing the real comfort of the user while considering energy conservation and environmental protection.

[0083] Based on the above content, in one embodiment, the method further includes:

[0084] Obtain the optimal comfort temperature of the next target period in the region where the air conditioning equipment is located;

[0085] Determine the comfort temperature difference value according to the optimal comfort temperature and the target set temperature, and display it to the user.

[0086] Among them, the optimal comfort temperature needs to consider not only the current season but also the region where the user is located. In the same season, the optimal comfort temperature of users will be different in different regions. For example, in northern and southern cities in October, the optimal comfort temperature in northern cities is lower than that in southern cities.

[0087] In an alternative embodiment, the following formula can be referred to when determining the optimal comfort temperature of a region:

[0088] Upper limit of comfort temperature:

[0089] T u = 0.231T out + 23.014

[0090] Optimal comfort temperature:

[0091] T b = 0.261T out + 17.54

[0092] Lower limit of comfort temperature:

[0093] T d = 0.211T out + 11.985

[0094] Among them, T u is the upper limit temperature of comfort; T b is the optimal comfort temperature; T d is the lower limit temperature of comfort; T out is the average monthly outdoor temperature of the region in previous years.

[0095] The difference between the optimal comfort temperature and the target set temperature can be used as the comfort temperature difference value. Among them, the comfort temperature difference value has positive and negative values for users to distinguish.

[0096] Users can judge whether to adjust the target set temperature according to the energy saving rate and in combination with the comfort temperature difference value. If the user feels that adjustment is needed, the adjusted target set temperature is input.

[0097] In an alternative embodiment, this method further includes:

[0098] In response to the adjusted target set temperature input by the user, recalculate the energy saving rate of the next target period and display it to the user.

[0099] That is to say, if the user feels that the current target set temperature has too high energy consumption and / or a large comfort temperature difference value, the user adjusts the target set temperature for the next target period through the mobile terminal. After the adjustment, the air conditioning device will recalculate the corresponding energy saving rate and comfort temperature difference value according to the adjusted target set temperature according to the foregoing method content, and display them to the user. Until the user is satisfied with the adjusted target set temperature, this method ends.

[0100] In summary, the embodiment of the present invention provides a method for determining a set temperature. By responding to the target set temperature of the next target period input by the user, the target environmental parameters of the next target period and the first total energy consumption of the current target period are obtained. The target environmental parameters include the target collection time and the target outdoor temperature corresponding to the target collection time. According to the target environmental parameters and the target set temperature, the second total energy consumption of the next target period is calculated through a preset fitting energy consumption formula. According to the first total energy consumption and the second total energy consumption, the energy saving rate of the next target period relative to the current target period is calculated and displayed to the user. In this way, through the estimated energy consumption of the next target period, when the user determines the target set temperature of the next target period, the user can intuitively understand the energy saving effect of executing the target set temperature. Assist the user to determine the temperature curve, avoid waste of cooling or heating, and take into account the comfort of the user at the same time.
