[0029] It should be understood that although the terms first, second, third, etc. may be used in the present disclosure to describe various information, such information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present disclosure, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the word "if" as used herein may be interpreted as "when" or "while" or "in response to determining".

[0030] To enable a user to understand the energy-saving effect that can be achieved by the selected energy-saving control mode, the present disclosure provides a method for determining the energy-saving amount, which can be applied to a thermostat or a user terminal, and the thermostat can be used to control an HVAC system.

[0031] The following embodiments will describe the method for determining the energy-saving amount provided by the present disclosure with reference to the accompanying drawings.

[0032] Figure 1 is a flowchart of the method for determining the energy-saving amount according to an exemplary embodiment of the present disclosure, as Figure 1 shown, the method for determining the energy-saving amount includes step 101 and step 102.

[0033] In step 101, device information of a heating, ventilation, and air conditioning (HVAC) system and regional information of the user's location are obtained.

[0034] In some embodiments, the device information of the HVAC system and the regional information of the user's location can be obtained through the user's response to the inquiry information. For example, the inquiry information may include "Please enter the city where you are located" and "Please enter the device model", etc.

[0035] Among them, the device information may include the brand and model of the HVAC system, the age and area of the house, and the energy source driving the HVAC system, etc., while the regional information may include the city name or postal code, etc.

[0036] In the case of obtaining the city name and / or postal code input by the user, the climate type, thermal zoning, standard building type, and meteorological information of the region can be determined according to the city name and / or postal code.

[0037] In some embodiments, the nearest city in the same climate zone in the database can be selected according to the user's location, and the required regional information can be simulated by methods such as difference calculation.

[0038] In step 102, in response to the energy-saving control mode and schedule selected by the user, determine the difference between the predicted energy consumption corresponding to the energy-saving control mode and schedule and the baseline energy consumption.

[0039] In the embodiments of the present disclosure, multiple energy-saving control modes can be provided for the user to choose. Each energy-saving control mode corresponds to multiple operating modes, and different operating modes correspond to different operating durations and temperature control ranges, where the operating duration can be determined according to the schedule selected by the user.

[0040] Based on the energy-saving control mode selected by the user, the temperature control range corresponding to the operating mode can be determined. Based on the schedule selected by the user, the operating duration corresponding to the operating mode can be determined. According to the temperature control range and operating duration corresponding to the operating mode, the energy consumption of the operating mode can be predicted. That is to say, in the case where the user selects the energy-saving control mode and schedule, the predicted energy consumption corresponding to the energy-saving control mode and schedule can be determined.

[0041] In one implementation manner, the energy-saving effect of the energy-saving control mode selected by the user can be reflected by the difference between the predicted energy consumption and the baseline energy consumption.

[0042] In another implementation manner, the energy-saving effect of the energy-saving control mode selected by the user can be reflected by the ratio of the difference between the predicted energy consumption and the baseline energy consumption to the baseline energy consumption.

[0043] The embodiments of the present disclosure obtain the device information of the heating, ventilation and air conditioning (HVAC) system, as well as the regional information of the user. In the case of obtaining the energy-saving control mode and schedule selected by the user, determine the difference between the predicted energy consumption corresponding to the energy-saving control mode and schedule and the baseline energy consumption, enabling the user to understand the energy that can be saved under the energy-saving control mode.

[0044] The reference energy consumption in the embodiments of the present disclosure can be determined according to the reference temperature control ranges corresponding to different operating modes and the default operating durations of each operating mode within a preset period, and the reference temperature control ranges and the default operating durations are determined according to the regional information.

[0045] That is to say, the meteorological information of the region can be obtained according to the regional information, and the reference temperature control ranges corresponding to each operating mode can be determined according to the meteorological information and relevant standards (ASHRAE Standard 55-2010). Among them, the operating modes can include a home mode, an out mode, and a sleep mode.

[0046] For example, the reference temperature control ranges corresponding to the above operating modes in a certain region are shown in Table 1.

[0047] Operating mode ST / °F ℃ Home mode 70～76 21.11～24.44 Away mode 56～82 13.33～27.78 Sleep mode 72～78 22.22～25.56

[0048] Table 1

[0049] In the embodiments of the present disclosure, the default operating durations of each operating mode can be set. Assuming that the preset period is one day, the default operating durations of each operating mode within one day can be set to 8 hours.

[0050] In the embodiments of the present disclosure, the expected energy consumption can be determined according to the target temperature control ranges corresponding to different operating modes and the target operating durations corresponding to each operating mode. The target temperature control ranges are determined according to the energy-saving control mode selected by the user, and the target operating durations are determined according to the schedule.

[0051] In the embodiments of the present disclosure, the reference energy consumption and the expected energy consumption are also determined according to the device information and the meteorological information related to the regional information. Among them, the temperature difference between indoors and outdoors can be determined according to the meteorological information, and the reference energy consumption and the expected energy consumption corresponding to the energy-saving control mode can be determined according to the temperature difference between indoors and outdoors.

[0052] In some embodiments, the purpose of energy saving can be achieved by adjusting the reference temperature control ranges corresponding to the operating modes. That is to say, the smaller the reference temperature control range maintained by the HVAC system in the corresponding operating mode, the more energy the HVAC system needs to consume to maintain the temperature within the reference temperature control range. For example, the reference temperature control range in the home mode is 21.11°C to 24.44°C. When the indoor temperature is lower than 21.11°C or higher than 24.44°C, the HVAC system will start to work. Assuming that the adjusted temperature control range in the home mode is 20°C to 25.6°C, when the indoor temperature is lower than 20°C or higher than 25.6°C, the HVAC system starts to work. That is to say, after adjusting the temperature control range, the HVAC system starts to work later than before adjusting the temperature control range, so as to achieve the purpose of saving energy consumption.

[0053] To distinguish from the reference temperature control range corresponding to the operating mode, the temperature control range corresponding to the adjusted operating mode is represented by the target temperature control range.

[0054] In some embodiments, the reference temperature control range can be adjusted according to different temperature differences to obtain the target temperature control ranges corresponding to different operating modes, that is, multiple energy-saving control modes can be set according to different adjustment temperature differences for users to select. For example, the energy-saving control modes can include a low energy-saving control mode, a medium energy-saving control mode, and a high energy-saving control mode. In the low energy-saving control mode, the adjustment temperature difference for the reference temperature control range is less than that in the medium energy-saving control mode, and the adjustment temperature difference for the reference temperature control range in the medium energy-saving control mode is less than that in the high energy-saving control mode. That is to say, the target temperature control ranges corresponding to the respective operating modes in the low energy-saving control mode are smaller than those corresponding to the respective operating modes in the medium energy-saving control mode, and the target temperature control ranges corresponding to the respective operating modes in the medium energy-saving control mode are smaller than those corresponding to the respective operating modes in the high energy-saving control mode.

[0055] As shown in Table 2, the reference temperature control ranges of different operating modes are adjusted using different temperature differences to obtain the target temperature control ranges corresponding to different operating modes.

[0056]

[0057]

[0058] Table 2

[0059] In some embodiments, in response to the user selecting the low energy-saving control mode, the target temperature control ranges corresponding to different operating modes in the low energy-saving control mode are obtained;

[0060] In response to the user selecting the medium energy-saving control mode, the target temperature control ranges corresponding to different operating modes in the medium energy-saving control mode are obtained;

[0061] In response to the user selecting the high energy-saving control mode, the target temperature control ranges corresponding to different operating modes in the high energy-saving control mode are obtained.

[0062] In the case where the user selects the low energy-saving control mode, the medium energy-saving control mode, or the high energy-saving control mode, but the user-set schedule is not obtained, the operating duration corresponding to each operating mode can adopt the default operating duration.

[0063] When the user selects the low energy-saving control mode, the medium energy-saving control mode, or the high energy-saving control mode, and the user's set schedule is obtained, the running duration corresponding to different operating modes can be adjusted according to the user's schedule, that is, the target running duration corresponding to each operating mode can be determined according to the user's schedule.

[0064] The following embodiments take the method for determining the energy-saving amount applied to the user terminal as an example and will be specifically described with reference to the accompanying drawings.

[0065] Figure 2 It is a schematic diagram of the energy-saving control modes for the user to select according to an exemplary embodiment of the present disclosure. As Figure 2 shown, in response to the user's selected energy-saving control mode, the corresponding energy-saving amount can be displayed at area 21. The energy-saving control modes for the user to select are displayed at area 22. Low represents the low energy-saving control mode, medium represents the medium energy-saving control mode, high represents the high energy-saving control mode, and custom represents that the user can customize the energy-saving control mode. When the user selects the low energy-saving control mode, the medium energy-saving control mode, or the high energy-saving control mode, the temperature difference in area 25 cannot be edited.

[0066] When the user selects the low energy-saving control mode, the medium energy-saving control mode, or the high energy-saving control mode, the default running duration and the target temperature control range are displayed in area 23. The user can edit the times of getting up, going out, coming home, and sleeping according to their own schedule, and determine the target running durations of the home mode, the sleep mode, and the out mode according to the times edited by the user.

[0067] In some embodiments, the user can customize the energy-saving control mode by customizing the target temperature control range or the temperature difference. That is to say, in response to the user's selected custom energy-saving control mode, the temperature difference customized by the user or the target temperature control range corresponding to different operating modes customized by the user is obtained; when the temperature difference customized by the user is obtained, the reference temperature control range in different operating modes is adjusted according to the temperature difference customized by the user to obtain the target temperature control range corresponding to different operating modes in the customized energy-saving control mode.

[0068] Still taking Figure 2 as an example, in response to the user's selected custom option, the user can customize the energy-saving control mode by editing the highest temperature and the lowest temperature, and can also customize the energy-saving control mode by adjusting the temperature difference displayed in area 25. Therefore, the highest temperature and the lowest temperature edited by the user, or the temperature difference adjusted by the user, can be obtained, and the target temperature control range of each operating mode in the customized energy-saving control mode is determined according to the adjusted temperature difference.

[0069] In some embodiments, in response to an energy-saving instruction issued by the user, the operation duration corresponding to each operation mode is adjusted proportionally to extend the operation duration of the away mode and shorten the operation duration of the home mode. When it is detected that the user turns on the energy-saving switch (Coast to cool), it is determined that an energy-saving instruction issued by the user is detected. In this case, the operation duration corresponding to each operation mode can be adjusted proportionally, or the operation duration corresponding to each operation mode can be adjusted to a pre-set operation duration.

[0070] Still taking Figure 2 as an example, in response to detecting that the user turns on the energy-saving switch 24, it is determined that an energy-saving instruction issued by the user is detected, and the operation duration corresponding to each operation mode is adjusted proportionally.

[0071] In the case where the user selects the low energy-saving control mode, the medium energy-saving control mode or the high energy-saving control mode, the operation duration corresponding to each operation mode can be obtained. For example, the operation durations corresponding to the home mode, the away mode and the sleep mode are all 8 hours. When it is detected that the user turns on the energy-saving switch, the operation duration corresponding to the home mode can be proportionally shortened to 6 hours, the operation duration corresponding to the away mode can be extended to 12 hours, and the operation duration corresponding to the sleep mode is 6 hours.

[0072] In some embodiments, the weight corresponding to each operation mode can be obtained; according to the target temperature control range corresponding to different operation modes, the target operation duration corresponding to each operation mode, and the weight corresponding to each operation mode, the estimated energy consumption corresponding to the energy-saving control mode is determined.

[0073] In one implementation manner, the weight corresponding to each operation mode can be determined by the time ratio of the operation duration corresponding to each operation mode to the preset period. For example, still assuming that the preset period is one day and the operation durations of the HVAC system in the home mode, the away mode and the sleep mode are the same, in this case, the time ratios of the home mode, the away mode and the sleep mode to one day are 1 / 3 respectively, that is, the weights corresponding to each operation mode are 0.51.

[0074] In another implementation manner, the weight corresponding to each operation mode can be pre-set. For example, the weight corresponding to the home mode can be set to 1.01, the weight corresponding to the away mode can be set to 0.19, and the weight corresponding to the sleep mode can be set to 0.95.

[0075] In yet another implementation manner, the increased or decreased duration corresponding to each operation mode can be pre-set. For example, the duration corresponding to the home mode can be set to be reduced by 30 minutes, the duration corresponding to the away mode can be set to be increased by 30 minutes, and the duration corresponding to the sleep mode remains unchanged.

[0076] In some embodiments, in order to improve the accuracy of determining energy consumption, an energy consumption coefficient may be considered when calculating energy consumption. The energy consumption coefficient is used to indicate the influence degree of building thermal parameters in different periods on energy consumption. In order to improve the accuracy of determining energy consumption, the coefficient of performance (COP) of the energy driving the HVAC system may also be considered when calculating energy consumption. In the case where the energy driving the HVAC system is detected to be other than the specified energy, according to the energy conversion relationship table, the coefficient of performance (COP) of the energy driving the HVAC system is obtained.

[0077] Among them, the specified energy may be primary energy. As shown in Table 3, the coefficient of performance (COP) of the energy driving the HVAC system can be obtained according to the conversion coefficient in the energy conversion relationship table.

[0079] Table 3

[0080] In the embodiments of the present disclosure, the energy saving amount can be determined through a pre-constructed model. Figure 3 FIG. is a schematic diagram of determining the energy saving amount through a model according to an exemplary embodiment of the present disclosure. As Figure 3 shown, a model can be constructed according to regional information, building envelope, HVAC system type, and the number of people in the room. Using this model, the baseline energy consumption can be determined according to the baseline temperature control range, the predicted energy consumption can be determined according to the target temperature control range, and the energy saving effect of the energy saving control mode can be determined through the predicted energy consumption and the baseline energy consumption.

[0081] The regional information, building envelope, HVAC system type, and the number of people in the room can be determined through the user's response to the query information.

[0082] Among them, the building envelope refers to the building envelope of the house where the HVAC system is installed. The building envelope may include two parts: transparent and opaque. The opaque building envelope includes walls, roofs, floors, etc., and the transparent building envelope includes windows, skylights, balcony doors, etc.

[0083] The HVAC system type can be set by the user to match the heat pump / non-heat pump in the database. The COP of the heat pump is defaulted to 3.0, and the heating heat source in the non-heat pump can set the efficiency to correspond to different fuel supplies.

[0084] In some embodiments, during the process of a user associating a thermostat or a user terminal with an HVAC system, area information, the building envelope, the form of the HVAC system, and the number of people in the room can be obtained. Based on the obtained information, the baseline energy consumption is determined, and the target temperature control ranges corresponding to each operating mode in the low energy-saving control mode, the medium energy-saving control mode, and the high energy-saving control mode are obtained. According to the target temperature control ranges corresponding to the operating modes in each energy-saving control mode and the default operating duration, the expected energy consumption of each energy-saving control mode is determined. Based on the baseline energy consumption and the expected energy consumption corresponding to each energy-saving control mode, the energy savings corresponding to each energy-saving control mode can be determined, and the energy savings corresponding to each energy-saving control mode are stored in a database.

[0085] In response to detecting that the user selects the low energy-saving control mode, the medium energy-saving control mode, or the high energy-saving control mode, the energy savings in the database can be directly retrieved and displayed.

[0086] In response to detecting the user-set schedule, the operating duration corresponding to each operating mode in the selected energy-saving control mode is adjusted to obtain the target operating duration corresponding to each operating mode. The expected energy consumption is recalculated according to the target operating duration corresponding to each operating mode, and the energy savings are determined based on the recalculated expected energy consumption and the baseline energy consumption.

[0087] In response to detecting that the user selects the custom option, after detecting that the user has set the temperature ranges for at home, away, and sleep, the energy savings can be calculated using interpolation based on the samples in the database.

[0088] Corresponding to the embodiments of the foregoing method, the present disclosure also provides a temperature control system, which includes a thermostat or a user terminal, and the thermostat or the user terminal is configured to execute any method of the present disclosure.
