Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to a method and device for controlling low-power standby of an air-conditioning system. Background Art

[0002] An air conditioner mainly includes a compressor, an indoor heat exchanger, a throttling component, and an outdoor heat exchanger that form a main refrigerant circuit. By circulating the refrigerant in the circuit formed by the compressor, the condenser, the throttling component, the evaporator, and the compressor, and along with the phase change of the refrigerant, the temperature of the indoor space where the indoor heat exchanger is located can be adjusted.

[0003] In the existing air-conditioning system, there are many regular application scenarios in actual use. For example, in an office scenario, it is usually only turned on during working hours on weekdays. However, during special time periods such as at night and on holidays, although the indoor unit is in the shutdown state, since the outdoor unit is still in the standby state, that is, there is still a certain power consumption in the compressor, electric heating, communication, drive module, etc., so considering the annual energy consumption, a large amount of power will still be consumed during the annual standby time. For users, this not only increases the electricity bill but also increases energy waste. Summary of the Invention

[0004] The present invention provides a method and device for controlling low-power standby of an air-conditioning system, which are used to solve the defect of standby energy waste during weekdays at night and on holidays in the prior art, and significantly reduce the standby power of the outdoor unit of the air-conditioning system, achieving an energy-saving effect.

[0005] The present invention provides a method for controlling low-power standby of an air-conditioning system, including: obtaining the usage situation of the air conditioner within a target time, where the usage situation of the air conditioner includes the shutdown duration and startup duration of the air conditioner; determining whether the shutdown duration of the air conditioner is less than a first preset threshold, and obtaining the cumulative startup and shutdown time based on the startup duration of the air conditioner and the shutdown duration of the air conditioner that is less than the first preset threshold; determining whether the cumulative startup and shutdown time is greater than a second preset threshold, and obtaining the ambient temperature outside the loop based on the cumulative startup and shutdown time being greater than the second preset threshold; determining the wake-up countdown duration according to the ambient temperature outside the loop, and based on the wake-up countdown duration being 0, controlling the system to switch to a deep low-power standby mode.

[0006] It should be noted that by determining whether the air conditioner shutdown duration in the obtained air conditioner usage situation is less than the first preset threshold, it is determined whether to accumulate the air conditioner startup duration and shutdown duration as the cumulative startup and shutdown time, and by determining whether the cumulative startup and shutdown time is greater than the second preset threshold, it is convenient to determine whether to obtain the outdoor ambient temperature, and according to the temperature range where the outdoor ambient temperature is located, the corresponding wake-up countdown duration is determined, so that when the wake-up countdown duration is 0, it is directly determined that the control system switches to the deep low-power standby mode, realizing precise control of entering and exiting the deep standby state, minimizing the standby power consumption to the greatest extent while meeting the user's usage requirements, avoiding standby energy waste during weekdays at night and holiday periods, being applicable to the air conditioner system for local control, not being restricted by the timed startup wake-up function, having higher applicability, stronger popularizability, and more precise and efficient energy-saving effect.

[0007] According to an air conditioner system low-power standby control method provided by the present invention, determining whether the air conditioner shutdown time is less than the first preset threshold includes: based on the air conditioner shutdown time being not less than the first preset threshold, obtaining the outdoor ambient temperature; according to the outdoor ambient temperature, determining the wake-up countdown duration, and based on the wake-up countdown duration being 0, the control system switches to the deep low-power standby mode.

[0008] It should be noted that when the air conditioner shutdown time is not less than the first preset threshold, it can be determined that the corresponding air conditioner is in the shutdown state, then the outdoor ambient temperature is directly obtained, and according to the outdoor ambient temperature, the wake-up countdown duration is determined to determine whether the control system switches to the deep low-power standby mode, so as to precisely control the entry and exit of the deep standby state through the air conditioner usage situation, minimizing the standby power consumption to the greatest extent while meeting the user's usage requirements, and avoiding standby energy waste during weekdays at night and holiday periods.

[0009] According to an air conditioner system low-power standby control method provided by the present invention, determining the wake-up countdown duration according to the outdoor ambient temperature includes: if the outdoor ambient temperature is greater than the first preset temperature, determining that the wake-up countdown duration is 0; if the outdoor ambient temperature is greater than the second preset temperature and less than or equal to the first preset temperature, determining that the wake-up countdown duration is the first preset duration; if the outdoor ambient temperature is greater than the third preset temperature and less than or equal to the second preset temperature, determining that the wake-up countdown duration is the second preset duration; if the outdoor ambient temperature is less than or equal to the third preset temperature, determining that the wake-up countdown duration is the third preset duration; wherein, the first preset temperature is greater than the second preset temperature, the second preset temperature is greater than the third preset temperature, the first preset duration is greater than 0 and less than the second preset duration, and the second preset duration is less than the third preset duration.

[0010] It should be noted that by adopting a judgment method that combines user habits and the outer ring temperature lower than the climate, to determine whether to set the wake-up countdown duration to 0 or a non-zero value, so as to facilitate determining whether to directly switch to the deep low-power standby mode according to the 0 wake-up countdown duration, or to generate an exit countdown command according to the non-zero wake-up countdown duration, and then determine whether to power on the control system or continue to enter the deep low-power standby mode according to whether a power-on command is received within the preset time after the wake-up countdown duration ends, thereby achieving precise control of the entry and exit of the deep low-power standby, improving the energy-saving effect while meeting the user's needs.

[0012] It should be added that by determining whether a power-on command is received within the preset time after the wake-up countdown duration ends to determine whether to power on. If a power-on command is received within the preset time after the wake-up countdown duration ends, it can be determined as a normal working day, so as to power on the control system and make the control system in the normal working mode, thereby precisely realizing the exit control of the deep low-power standby and ensuring minimizing the standby power consumption to the greatest extent while meeting the user's usage requirements.

[0014] It should be noted that by determining whether a power-on command is received within the preset time after the wake-up countdown duration ends to determine whether the control system needs to switch to the deep low-power standby mode. If a power-on command is not received within the preset time after the wake-up countdown duration ends, it can be determined as a rest day such as a weekend or a holiday, so that the control system switches to the deep standby mode, minimizing the standby power consumption to the greatest extent while meeting the user's usage requirements and avoiding standby energy waste during the night on weekdays and holiday periods.

[0015] A low - energy standby control method for an air - conditioning system provided by the present invention to determine whether the cumulative on - off time is greater than a second preset threshold includes: based on the cumulative on - off time not being greater than the second preset threshold, re - obtaining the air - conditioning usage situation within the target time; determining whether the air - conditioning shutdown time in the re - obtained air - conditioning usage situation is less than a first preset threshold, and using the air - conditioning startup duration in the re - obtained air - conditioning usage situation and the re - obtained air - conditioning shutdown time less than the first preset threshold to update the cumulative on - off time; and re - determining whether the updated cumulative on - off time is greater than the second preset threshold.

[0016] It should be noted that the cumulative on - off time is calculated by using the air - conditioning startup duration and the air - conditioning shutdown duration less than the first preset threshold, so as to directly obtain the outer - ring temperature when the cumulative on - off time is greater than the second preset threshold, thereby facilitating the subsequent setting of the corresponding wake - up countdown duration according to the temperature range interval where the outer - ring temperature is located.

[0027] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the scope of protection of the present invention.

[0028] Figure 1 The schematic flowchart of a low - energy - consumption standby control method for an air - conditioning system according to the present invention is shown. The method includes: S11. Obtain the air - conditioning usage situation within the target time. The air - conditioning usage situation includes the air - conditioning shutdown duration and the air - conditioning startup duration; S12. Determine whether the air - conditioning shutdown duration is less than a first preset threshold, and obtain the cumulative startup - shutdown time according to the air - conditioning startup duration and the air - conditioning shutdown duration less than the first preset threshold; S13. Determine whether the cumulative startup - shutdown time is greater than a second preset threshold, and obtain the outer - loop temperature based on the fact that the cumulative startup - shutdown time is greater than the second preset threshold; S14. Determine the wake - up countdown duration according to the outer - loop temperature, and based on the fact that the wake - up countdown duration is 0, control the system to switch to the deep low - energy - consumption standby mode.

[0029] It should be noted that the step numbers "S1N" in this specification do not represent the sequence of the low - energy - consumption standby control method for the air - conditioning system. The following specifically combines Figures 2 - 4 to describe the low - energy - consumption standby control method for the air - conditioning system of the present invention.

[0030] In step S11, obtain the air - conditioning usage situation within the target time. The air - conditioning usage situation includes the air - conditioning shutdown duration and the air - conditioning startup duration.

[0031] In this embodiment, obtaining the air conditioner usage situation within the target time includes: obtaining the power-on and power-off records within the target time; and determining, according to the power-on and power-off records, the time for each switch from power-on to power-off and the time for each switch from power-off to power-on, so as to obtain the air conditioner usage situation.

[0032] It should be noted that the target time can be set according to actual design requirements, such as one day, and no further limitation is made here. In addition, by obtaining the power-on and power-off records within the target time, it is convenient to determine the time for each switch from power-on to power-off and the time for each switch from power-off to power-on within the target time, so as to determine the corresponding air conditioner usage situation, thereby facilitating subsequent precise control of entering and exiting deep standby based on the obtained air conditioner usage situation within the target time, minimizing standby power consumption to the greatest extent while meeting the user's usage requirements, and avoiding standby energy waste during weekdays at night and holiday periods.

[0033] Further, obtaining the power-on and power-off records within the target time includes: starting timing from the moment when the system is powered on for the first time, and recording the system power-on and power-off switching states; and obtaining the power-on and power-off records within the target time according to the recorded system power-on and power-off switching states.

[0034] It should be noted that starting to record from the moment when the system is powered on for the first time to record the power-on and power-off switching states, so as to facilitate determining the power-on and power-off records within the target time according to the recorded power-on and power-off switching states, so as to accurately obtain the power-on and power-off times within the target time, and thus facilitate subsequent determination of the air conditioner usage situation.

[0035] Step S12, determining whether the air conditioner shutdown duration is less than a first preset threshold, and obtaining the cumulative power-on and power-off time according to the air conditioner startup duration and the air conditioner shutdown duration less than the first preset threshold.

[0036] It should be added that when the air conditioner shutdown time is less than the first preset threshold, it can be determined that the corresponding air conditioner shutdown time is rest time, such as lunch break, etc. Therefore, the first preset threshold can be set according to the actual lunch break duration and design requirements. For example, a value within the range of (0, 3h] can be selected, and no further limitation is made here. In addition, the cumulative power-on and power-off time represents the sum of the power-on time and the power-off time.

[0037] In an alternative embodiment, referring to Figure 2 , determining whether the air conditioner shutdown time is less than a first preset threshold includes: based on the air conditioner shutdown time being not less than the first preset threshold, obtaining the outer ring temperature; determining the wake-up countdown duration according to the outer ring temperature, and based on the wake-up countdown duration being 0, controlling the system to switch to the deep low-power standby mode.

[0038] It should be noted that when the air conditioner shutdown time is not less than the first preset threshold, it can be determined that the corresponding air conditioner is in the shutdown state, and then the outside ambient temperature is directly obtained. Based on the outside ambient temperature, the wake-up countdown duration is determined to determine whether to control the system to switch to the deep low-power standby mode, so as to accurately control the entry and exit of the deep standby through the air conditioner usage, minimize the standby power consumption to the greatest extent while meeting the user's usage requirements, and avoid standby energy waste during weekdays at night and holiday periods.

[0039] Step S13: Determine whether the cumulative on-off time is greater than the second preset threshold, and based on the cumulative on-off time being greater than the second preset threshold, obtain the outside ambient temperature.

[0040] It should be added that the second preset threshold can be set according to the actual project situation. For example, any value within 8h - 12h can be selected, and no further limitation is made here.

[0041] In addition, obtaining the outside ambient temperature includes: obtaining the value of the outside ambient temperature sensor within the prior target time according to the target time; obtaining the outside ambient temperature based on the value of the outside ambient temperature sensor within the prior target time. It should be noted that the prior target time is the target time obtained in the previous acquisition of the currently obtained target time. For example, if the current target time is a certain day at 1 day time, the prior target time is the day before a certain day. In addition, by obtaining the value of the outside ambient temperature sensor within the prior target time, it is convenient to determine the average value of the outside ambient temperature within the prior target time and use it as the outside ambient temperature to be obtained, so as to facilitate setting the corresponding wake-up countdown duration according to the temperature range interval where the outside ambient temperature is located.

[0042] In an alternative embodiment, determining whether the cumulative on-off time is greater than the second preset threshold includes: based on the cumulative on-off time not being greater than the second preset threshold, re-obtaining the air conditioner usage within the target time; determining whether the air conditioner shutdown time in the re-obtained air conditioner usage is less than the first preset threshold, and updating the cumulative on-off time using the air conditioner on-time duration in the re-obtained air conditioner usage and the re-obtained air conditioner shutdown time less than the first preset threshold; re-determining whether the updated cumulative on-off time is greater than the second preset threshold.

[0043] It should be noted that when obtaining the air conditioner usage within the target time, since it is obtained in real time, there may be a situation where the current cumulative on-off time is not greater than the second preset threshold, but as time passes, the updated cumulative on-off time is greater than the second preset threshold. Therefore, when the cumulative on-off time is not greater than the second preset threshold, it is necessary to re-obtain the air conditioner usage to update the cumulative on-off time.

[0044] It should be noted that the cumulative on-off time is calculated by using the air conditioner startup duration and the air conditioner shutdown duration less than the first preset threshold. When the cumulative on-off time is greater than the second preset threshold, the external ambient temperature is directly obtained, so as to facilitate setting the corresponding wake-up countdown duration according to the temperature range interval where the external ambient temperature is located subsequently.

[0045] Step S14, determine the wake-up countdown duration according to the external ambient temperature, and based on the wake-up countdown duration being 0, the control system switches to the deep low-power standby mode.

[0046] In this embodiment, determining the wake-up countdown duration according to the external ambient temperature includes: if the external ambient temperature is greater than the first preset temperature, determining that the wake-up countdown duration is 0; if the external ambient temperature is greater than the second preset temperature and less than or equal to the first preset temperature, determining that the wake-up countdown duration is the first preset duration; if the external ambient temperature is greater than the third preset temperature and less than or equal to the second preset temperature, determining that the wake-up countdown duration is the second preset duration; if the external ambient temperature is less than or equal to the third preset temperature, determining that the wake-up countdown duration is the third preset duration; wherein, the first preset temperature is greater than the second preset temperature, the second preset temperature is greater than the third preset temperature, the first preset duration is greater than 0 and less than the second preset duration, and the second preset duration is less than the third preset duration.

[0047] It should be noted that the first preset temperature, the second preset temperature, and the third preset temperature can be set according to the user's climate and the corresponding external ambient temperature.

[0048] It is worth noting that by adopting a judgment method that combines the user's habits and the external ambient temperature of the climate, to determine whether to set the wake-up countdown duration to 0 or non-0, so as to facilitate determining whether to directly switch to the deep low-power standby mode according to the 0 wake-up countdown duration, or to generate an exit countdown instruction according to the non-0 wake-up countdown duration, and then determine whether to receive a startup instruction within the preset time after the wake-up countdown duration ends, and further determine whether the control system starts up or continues to enter the deep low-power standby mode, so as to achieve precise control of the entry and exit of the deep low-power standby, and improve the energy-saving effect while meeting the user's needs.

[0049] In an alternative embodiment, after determining the wake-up countdown duration according to the external ambient temperature, it further includes: based on the wake-up countdown duration being non-0, generating an exit countdown instruction according to the wake-up countdown duration and executing it; determining whether a startup instruction is received within the preset time after the wake-up countdown duration ends. If a startup instruction is received within the preset time after the wake-up countdown duration ends, the control system starts up, and the control system is in the normal working mode.

[0050] It should be added that the preset time can be set according to the actual usage habits and design requirements, and no further limitation is made here.

[0051] It should be noted that by determining whether a power-on instruction is received within a preset time after the end of the wake-up countdown duration, it is determined whether to power on. If a power-on instruction is received within the preset time after the end of the wake-up countdown duration, it can be determined as a normal working day. Refer to Figure 3 , to control the system to power on and the system to be in a normal working mode, so as to accurately realize the exit control of deep low-power standby, ensuring to minimize the standby power consumption while meeting the user's usage requirements.

[0052] In addition, determining whether a power-on instruction is received within a preset time after the end of the wake-up countdown duration includes: if no power-on instruction is received within the preset time after the end of the wake-up countdown duration, the control system switches to enter the deep low-power standby mode.

[0053] It should be noted that by determining whether a power-on instruction is received within a preset time after the end of the wake-up countdown duration, it is determined whether the control system needs to switch to enter the deep low-power standby mode. If no power-on instruction is received within the preset time after the end of the wake-up countdown duration, it can be determined as a rest day such as a weekend or a holiday. Refer to Figure 4 , so that the control system switches to enter the deep standby mode, minimizing the standby power consumption while meeting the user's usage requirements, and avoiding standby energy waste during the night on weekdays and holiday periods.

[0054] In summary, in the embodiment of the present invention, by determining whether the air conditioner shutdown duration in the obtained air conditioner usage situation is less than a first preset threshold, it is determined whether to accumulate the air conditioner on duration and shutdown duration as the cumulative on-off time, and by determining whether the cumulative on-off time is greater than a second preset threshold, it is convenient to determine whether to obtain the external ambient temperature, and according to the temperature range where the external ambient temperature is located, the corresponding wake-up countdown duration is determined, so that when the wake-up countdown duration is 0, it is directly determined that the control system switches to enter the deep low-power standby mode, realizing precise control of entering and exiting deep standby, minimizing the standby power consumption while meeting the user's usage requirements, avoiding standby energy waste during the night on weekdays and holiday periods, being applicable to the air conditioner system with local control, not being restricted by the timed power-on wake-up function, having higher applicability, stronger popularization, and more accurate and efficient energy-saving effect.
