The energy-saving control method and device of the air conditioner and the air conditioner are described below with reference to fig. 1 to 6.
According to an embodiment of the first aspect of the present invention, referring to fig. 1, the method for controlling energy saving of an air conditioner provided by the present invention mainly includes the following steps:
s101, acquiring a mains supply state.
The step is a core monitoring link of the whole method, and whether the commercial power is normally supplied or not can be detected and judged in real time through equipment such as a sensor or an intelligent ammeter arranged in a circuit. When the mains supply is abnormal, the step can quickly identify and capture the power-off signal.
S102, under the condition that the commercial power is in a power-off state, switching the standby power supply to supply power for the air conditioner and other electrical appliances.
When the commercial power is confirmed to be powered off, a standby power supply (such as a generator, an energy storage battery and the like) is automatically triggered to start supplying power to the household appliances, so that the basic life requirements are not influenced. This process includes a fast switching mechanism and the ability to stabilize the power supply, avoiding damage to the appliance by voltage fluctuations due to power supply switching.
S103, controlling the air conditioner to operate in a first energy saving mode in the energy saving modes.
In order to effectively allocate limited standby power capacity, the air conditioner is forcibly adjusted to a preset first power saving mode, i.e., a power saving mode. Such modes include, but are not limited to, reducing cooling/heating power, adjusting compressor operating frequency, limiting cold output, etc., to reduce energy consumption of the air conditioner.
The first energy saving mode is designed to ensure the basic functional operation of the air conditioner while minimizing the need for an overall power load so that other necessary home appliances (e.g., electric lamps, televisions, refrigerators, washing machines, water heaters, etc.) can also operate normally under limited power conditions.
Therefore, the energy-saving control method of the air conditioner provided by the embodiment of the invention can dynamically adjust the operation power of the air conditioner according to the actual power supply capacity, ensure that the working efficiency of the air conditioner is maximized while meeting the normal power consumption requirements of other household appliances, realize the effective distribution and the optimal utilization of power resources, and meet the operation requirements of all electric equipment in a household, thereby obviously improving the use experience of a user in an unstable power-off environment of a power grid.
According to an embodiment of the present invention, referring to fig. 2, the energy saving control method of the air conditioner of the present invention further includes the steps of:
S201, after the air conditioner is controlled to operate in a first energy saving mode for a preset period of time, the indoor ring temperature is obtained.
After the air conditioner enters the first energy saving mode and operates for a period of time (such as half an hour, one hour and other preset time periods), the current indoor environment temperature data are automatically collected.
S202, determining that the indoor ring temperature does not reach the first target temperature, and controlling the air conditioner to operate in a second energy-saving mode in the energy-saving modes according to the difference value between the indoor ring temperature and the first target temperature; wherein the operating power of the second energy saving mode is greater than the operating power of the first energy saving mode.
If the detected indoor temperature still does not reach the preset first target temperature (i.e. the comfort temperature expected by the user), the difference between the actually detected indoor temperature and the target temperature is analyzed, and the working mode of the air conditioner is further adjusted to the second energy-saving mode according to the difference.
It will be appreciated that the second energy saving mode, while still in the energy saving category, operates at a higher power than the first energy saving mode, meaning that the air conditioner will provide more cooling/heating capacity to more quickly approach or reach the set target temperature, thereby improving the user experience.
In the energy-saving control method of the air conditioner provided by the embodiment of the invention, besides the basic mains supply state detection and standby power supply switching mechanism, the function of dynamically adjusting the running mode of the air conditioner for the indoor environment temperature is further introduced, through the hierarchical energy-saving control strategy, the energy is effectively saved under the condition of power failure or unstable power grid, the room temperature can be ensured to be quickly adjusted when necessary, the comfort level of a user is improved, and meanwhile, more power resources are prevented from being wasted because the ideal temperature cannot be reached for a long time. The invention can enable the air conditioner to realize more refined and intelligent operation management in a complex electricity utilization environment.
According to one embodiment of the invention, in the second energy saving mode, the air conditioner is provided with a plurality of energy saving gears;
According to the difference value between the indoor ring temperature and the first target temperature, controlling the air conditioner to operate in a second energy-saving mode in the energy-saving modes, specifically comprising the following steps:
if the difference value between the indoor ring temperature and the first target temperature is a first threshold value, controlling the air conditioner to operate in a first energy saving gear;
If the difference value between the indoor ring temperature and the first target temperature is a second threshold value, controlling the air conditioner to operate in a second energy-saving gear;
If the difference value between the indoor ring temperature and the first target temperature is a third threshold value, controlling the air conditioner to operate in a third energy-saving gear;
Wherein the first threshold is less than the second threshold, and the second threshold is less than the third threshold; the operating power of the first energy saving gear is smaller than the operating power of the second energy saving gear, and the operating power of the second energy saving gear is smaller than the operating power of the third energy saving gear.
In the energy-saving control method of the air conditioner provided by the embodiment of the invention, a plurality of different energy-saving gears are designed in the second energy-saving mode, and the step-by-step lifting of the running power of the air conditioner is realized through the judgment of the refined temperature difference value, and the method comprises the following steps: according to the difference value between the indoor ring temperature and the first target temperature, selecting a corresponding energy-saving gear specifically comprises the following steps:
and when the difference value between the actually detected indoor environment temperature and the preset first target temperature is a first threshold value, switching the air conditioner to a first energy-saving gear operation. The gear has the lowest running power, is mainly suitable for the conditions of small temperature difference and only fine adjustment, and can achieve the purpose of effective energy saving.
If the difference reaches a second larger threshold, indicating that a larger refrigerating/heating capacity is needed to quickly adjust the room temperature, the air conditioner is controlled to operate in a second energy-saving gear, and the operating power of the air conditioner is higher than that of the first energy-saving gear.
When the difference value is further increased to the third threshold value, the higher-efficiency working state is required to quickly approach or reach the target temperature, so that the air conditioner is controlled to enter a third energy-saving gear, the running power of the gear is maximum, and the running power of the gear is highest in all energy-saving gears.
According to the embodiment of the invention, through the sectional and step-type energy-saving gear regulating mechanism, the air conditioner can flexibly adjust the working strength according to the actual gap between the real-time room temperature and the set target temperature, so that the energy is effectively saved in an unstable environment of a power grid, the requirements of users on comfort level are met, and the waste of electric power resources is reduced to the greatest extent. The invention has high intellectualization and adaptability, and optimizes the comprehensive performance of the household electric equipment under the complex power supply condition.
According to one embodiment of the present invention, the energy saving control method of the air conditioner of the present invention further includes:
Determining that the indoor ring temperature does not reach the second target temperature, controlling the air conditioner to exit the energy-saving mode, and operating in a full-load mode; wherein, in the cooling mode, the second target temperature is lower than the first target temperature, and in the heating mode, the second target temperature is higher than the first target temperature.
Specifically, when it is determined that the indoor ambient temperature does not reach the second target temperature, if the air conditioner is operated in the cooling mode and it is detected that the indoor ambient temperature fails to drop to the second target temperature lower than the first target temperature, the energy saving mode will not be maintained, and the air conditioner is controlled to exit the energy saving mode and enter the full load (i.e., full power) mode of operation to reduce the indoor temperature to the set minimum comfort threshold as soon as possible.
In contrast, in the heating mode, if the indoor ambient temperature fails to rise to the second target temperature higher than the first target temperature, the air conditioner is also controlled to exit the energy saving mode, and full power heating is performed to rapidly raise the indoor temperature to a higher comfort level.
The embodiment of the invention ensures that under specific conditions (such as extreme heat or cold), the requirement of a user for quickly reaching the proper room temperature can be preferentially met even under the condition that the power grid is unstable. By flexibly switching different operation modes, the invention not only realizes the energy-saving aim, but also ensures that the air conditioner can provide sufficient cold and heat when necessary, and improves the user experience and comfort.
According to an embodiment of the present invention, referring to fig. 3, the energy saving control method of the air conditioner of the present invention further includes the steps of:
S301, when the mains supply is restored to the power-on state from the power-off state, and the air conditioner exits the energy-saving mode and operates in the full-load mode, acquiring the total load current of the electric appliance.
When the power grid resumes normal power supply, the air conditioner can automatically exit the energy-saving mode and turn to the default full-load mode operation. At the same time, the total current consumption of all appliances (including air conditioners and other appliances) in the home is monitored in real time.
S302, determining that the total load current of all the electric appliances exceeds rated current, controlling the air conditioner to jump to a third energy-saving mode in the energy-saving modes after the air conditioner is stopped and cannot operate, and detecting whether the air conditioner operates or not.
If it is detected that the total load of all the electric appliances is too large and exceeds the rated current limit of the household circuit, the air conditioner is stopped due to overload protection, measures are immediately taken, the air conditioner is adjusted to enter a third energy-saving mode, and the energy consumption is reduced so as to reduce the influence on the whole circuit.
Meanwhile, whether the air conditioner can be started and operated normally after being switched to the third energy-saving mode is confirmed.
S303, if the air conditioner does not operate, controlling the air conditioner to jump to a fourth energy-saving mode in the energy-saving modes; wherein, the operation power of the third energy saving mode is larger than the operation power of the fourth energy saving mode. And, the operating power of the third energy saving mode may be smaller than the operating power of the first energy saving mode.
If the air conditioner still fails to start or continuously run even in the third energy-saving mode, the working power of the air conditioner is further reduced to enable the air conditioner to enter a fourth energy-saving mode, the working power of the air conditioner in the mode is the lowest, the burden on a circuit is reduced to the greatest extent, at least partial refrigeration/heating functions are maintained, and meanwhile potential safety hazards caused by overload are avoided.
Therefore, the embodiment of the invention can effectively solve the problem of overload of the electric load possibly encountered after the mains supply is electrified, and through a series of intelligent regulation and control processes, the running state of the air conditioner can be dynamically regulated according to the actual electricity utilization environment, and on the premise of ensuring safe electricity utilization, the electric power utilization of household appliances is reasonably distributed and optimized, especially under the condition of instant heavy current impact possibly occurring at the early stage of the mains supply restoration, the overload shutdown phenomenon is effectively avoided, and the user use experience and the service life of the appliances are improved.
According to an embodiment of the present invention, referring to fig. 3, the energy saving control method of the air conditioner of the present invention further includes the steps of:
S304, if the air conditioner is not operated after being jumped to the fourth energy-saving mode, other electric appliances are controlled to be closed, and the air conditioner is operated in a full-load mode.
Specifically, when the fourth energy saving mode, which adjusts the air conditioner to the lowest energy consumption, is not normally started or maintained to operate (possibly due to serious overload of the household circuit or other power supply problems), further measures are taken.
In order to ensure the basic function of the air conditioner, the operation of turning off a part of unnecessary other home appliances is automatically performed, and by reducing the load of the whole circuit, it is ensured that sufficient power is supplied to the air conditioner.
After the partial electric appliances are closed, the air conditioner tries to be started again and enters a full-load mode to run so as to reach a set temperature target as soon as possible, and the requirements of users on indoor environment comfort level are met.
The embodiment of the invention can intelligently decide and optimize the resource allocation when facing the limitation of the power supply condition. Through the on-off state of the electric appliances in the home under the dynamic regulation and control, the key equipment (such as an air conditioner) can be ensured to restore full-power operation when necessary, so that the flexibility and the adaptability of the whole system are enhanced, and the user experience is improved. Meanwhile, the self-adaptive control strategy is beneficial to reasonably utilizing limited power resources in an unstable power grid environment, and balances the use of electric appliances and energy efficiency.
It can be understood that the energy-saving mode operation power is a percentage of the full-load mode operation power, for example, the operation power of the first energy-saving mode is 40% of the full-load mode operation power, the operation power of the second energy-saving mode is 60% of the full-load mode operation power, and the third energy-saving mode and the fourth energy-saving mode are the same, and can be specifically designed and adjusted according to actual working conditions.
According to an embodiment of the present invention, referring to fig. 4, the energy saving control method of the air conditioner of the present invention further includes:
S401, under the condition that the mains supply is in a power-on state, acquiring a user setting instruction.
When the power supply of the power grid is stable, a user can directly send an operation instruction to the air conditioner through a remote controller, a smart phone application program or other smart devices. These instructions include, but are not limited to, temperature setting, operating mode selection (cooling, heating, dehumidification, etc.), wind speed adjustment, timed on-off, etc.
S402, controlling the operation of the air conditioner according to the user setting instruction.
Receiving and analyzing the setting requirement of the user in real time, and automatically adjusting the working state of the air conditioner according to the setting requirement. This means that the user can personalize the parameters of the air conditioner to the individual needs and comfort criteria entirely under conditions of sufficient power supply. The user is free to decide whether to enable the energy saving mode or to select a specific energy saving gear. Even under the condition of not considering energy saving priority, effective response can be carried out when a user sets a higher energy consumption operation mode, and the air conditioner can be ensured to work normally according to instructions.
The embodiment of the invention ensures the autonomous control of the user on the use experience of the air conditioner under the normal power supply condition. The user comfort is met, and meanwhile the capability of flexibly switching to the energy-saving mode according to actual requirements is reserved, so that the dual optimization of high efficiency and user experience is realized.
The energy-saving control device of the air conditioner provided by the invention is described below, and the energy-saving control device of the air conditioner described below and the energy-saving control method of the air conditioner described above can be referred to correspondingly.
According to an embodiment of the second aspect of the present invention, referring to fig. 5, the present invention further provides an energy saving control device of an air conditioner, which mainly includes: an acquisition module 501, a switching module 502 and a control module 503. The acquiring module 501 is configured to acquire a power supply state of the mains supply 603; the switching module 502 is configured to switch the standby power supply 604 to supply power to the air conditioner and other electrical appliances when the utility power 603 is in a power-off state; the control module 503 is configured to control the air conditioner to operate in a first energy saving mode of the energy saving modes.
Specifically, the acquiring module 501 is responsible for monitoring and acquiring the power supply state information of the mains supply in real time, so as to ensure that whether the mains supply is in a normal power supply state can be accurately and timely judged; when the acquisition module 501 detects a mains outage, the switching module 502 is immediately activated to automatically switch the power supply from the mains to a backup power supply, such as a generator, an energy storage battery or other backup energy system, ensuring that the air conditioner and other important appliances can still obtain a stable power supply during the mains outage.
And after the mains supply is powered off and is successfully switched to the standby power supply, the control module 503 starts executing the energy saving strategy, and adjusts the air conditioner to a preset first energy saving mode. In the mode, the air conditioner can work according to preset low-energy consumption parameters, such as measures of reducing refrigerating/heating capacity, reducing operation frequency of a compressor, optimizing wind speed and the like, so that energy consumption is effectively reduced, and limited electric power resources are reasonably distributed for other household appliances.
