Description

空调器的控制方法、控制装置和空调器Air conditioner control method, control device and air conditioner 技术领域Technical Field
本发明涉及空调器的控制技术领域，特别是涉及一种空调器的控制方法、控制装置和空调器。The present invention relates to the technical field of air conditioner control, and in particular to a control method and a control device of an air conditioner and an air conditioner.
背景技术Background technique
空调，无论是炎热的夏季还是寒冷的冬季都是必不可少的家用电器，但是空调的耗电量也是不容忽视的一个方面。通常情况下，空调使用的都是市电，但是对于大型的公共场所，如医院，公司，当市电出现故障时，就需要启动备用发电机来供电，这个时候，空调会占用电路中的大部分电力，导致备用电力消耗加速，可供给的设备减少。Air conditioners are essential household appliances, whether in hot summer or cold winter, but the power consumption of air conditioners is also an aspect that cannot be ignored. Normally, air conditioners use city electricity, but for large public places such as hospitals and companies, when the city electricity fails, it is necessary to start a backup generator to supply power. At this time, the air conditioner will occupy most of the power in the circuit, resulting in accelerated consumption of backup power and a reduction in the number of devices that can be supplied.
当市电故障时，备用电源启动，用户需要手动操作遥控器按钮，开启发电机模式，以低功耗的方式运行空调。这种方案本身存在局限性，即当外部使用发电机后，如果用户忘记操作遥控器，会导致空调仍然按照市电的模式运行。但是发电机的发电方式毕竟属于临时使用方案，按照市电模式功能运行，功耗会比较大，导致发电机供电时间有限。When the mains fails, the backup power source starts, and the user needs to manually operate the remote control button to turn on the generator mode and run the air conditioner in a low-power mode. This solution itself has limitations, that is, when the generator is used externally, if the user forgets to operate the remote control, the air conditioner will still run in the mains mode. However, the generator's power generation method is a temporary use solution after all. If it runs in the mains mode, the power consumption will be relatively large, resulting in a limited generator power supply time.

图1是所示出的是一种空调器的控制方法的流程图，该控制方法用于在非市电供电的状态下对空调器进行控制，以降低空调器的能耗、提高备用电源的续航能力，并提高室内环境的舒适度。下面结合图1所示出的流程，对本申请的空调器的控制方法做详细的介绍。FIG1 is a flow chart of a control method for an air conditioner, which is used to control the air conditioner when it is not powered by mains electricity, so as to reduce the energy consumption of the air conditioner, improve the endurance of the backup power supply, and improve the comfort of the indoor environment. The following is a detailed introduction to the control method of the air conditioner of the present application in conjunction with the process shown in FIG1.
如图1所示，本申请的空调器的控制方法，包括如下步骤：As shown in FIG1 , the control method of the air conditioner of the present application comprises the following steps:
步骤S1：当市电入户灯熄灭且其他入户灯亮起时，启动空调器的节能模式。Step S1: When the mains power entrance light is off and other entrance lights are on, start the energy-saving mode of the air conditioner.
在本实施例中，可以市电以及备用电源的供电线路上分别设置相应的入户灯，并且在各入户灯处设置相应的感光元件，例如在各入户灯处设置相应的光敏二极管；当市电或者备用电源处于供电状态时，对应的入户灯会得电并开始发光，对应的光敏二极管会感应到光信号而导通。因此，可以根据各感光元件是否感应到光信号，判断市电和备用电源的供电状态。当市电入户灯熄灭且其他入户灯亮起时，可以认为市电处于断电状态，空调器由蓄电池、发电机等备用电源供电，因此启动空调器的节能模式，以降低空调器的能耗，提高备用电源的续航能力。In this embodiment, corresponding house entrance lights can be respectively arranged on the power supply lines of the mains and the backup power supply, and corresponding photosensitive elements can be arranged at each house entrance light, for example, corresponding photosensitive diodes can be arranged at each house entrance light; when the mains or the backup power supply is in the power supply state, the corresponding house entrance light will be powered and start to emit light, and the corresponding photosensitive diode will sense the light signal and turn on. Therefore, the power supply state of the mains and the backup power supply can be judged according to whether each photosensitive element senses the light signal. When the mains house entrance light goes out and other house entrance lights are on, it can be considered that the mains is in a power-off state, and the air conditioner is powered by a backup power supply such as a battery or a generator, so the energy-saving mode of the air conditioner is started to reduce the energy consumption of the air conditioner and improve the endurance of the backup power supply.
步骤S2：在空调器的节能模式启动时，如果空调器启动了制冷功能或者制热功能，则调整压缩机的运行频率至最低频率，并判断室内的环境温度和设定温度是否满足预设条件。Step S2: When the energy-saving mode of the air conditioner is started, if the air conditioner starts the cooling function or the heating function, the operating frequency of the compressor is adjusted to the lowest frequency, and it is determined whether the indoor ambient temperature and the set temperature meet the preset conditions.
空调器具有多种功能，例如换气功能、制热功能、制冷功能、杀菌功能等，当空调器执行其中一个或多个功能时，空调器会存储有该一个或多个功能对应的标识。当空调器的节能模式启动时，可以读取所存储的标识，通过存储的标识得到空调器是否启动制冷功能或制热功能；如果空调器没有启动制冷功能和制热功能，则控制空调器关机，以减少空调器的能耗；反之，如果空调器启动了制冷功能或者制热功能，则关闭其他的功能，仅保留该空调器的制冷功能或者制热功能以减少空调器的能耗。The air conditioner has multiple functions, such as ventilation function, heating function, cooling function, sterilization function, etc. When the air conditioner performs one or more of these functions, the air conditioner will store the corresponding identification of the one or more functions. When the energy-saving mode of the air conditioner is started, the stored identification can be read to obtain whether the air conditioner starts the cooling function or the heating function; if the air conditioner does not start the cooling function and the heating function, the air conditioner is controlled to shut down to reduce the energy consumption of the air conditioner; on the contrary, if the air conditioner starts the cooling function or the heating function, other functions are turned off, and only the cooling function or the heating function of the air conditioner is retained to reduce the energy consumption of the air conditioner.
当空调启动了制冷功能或者制热功能，则调整压缩机的运行频率至最低 频率，该最低频率是压缩机的一个特征参数，当压缩机以该最低频率运行时，可以驱动空调器的制冷剂正常循环，空调器可以执行制冷功能或者制热功能；而当压缩机的频率小于该最低频率时，制冷剂将不能正常循环，空调器无法执行制热功能或者制冷功能，在本实施例中，该最低频率可以为0.1Hz。当压缩机的运行频率为最低频率时，可以将压缩机的能耗降到最低。When the air conditioner starts the cooling function or heating function, the operating frequency of the compressor is adjusted to the lowest Frequency, the minimum frequency is a characteristic parameter of the compressor. When the compressor operates at the minimum frequency, the refrigerant of the air conditioner can be driven to circulate normally, and the air conditioner can perform the cooling function or the heating function; when the frequency of the compressor is less than the minimum frequency, the refrigerant will not circulate normally, and the air conditioner cannot perform the heating function or the cooling function. In this embodiment, the minimum frequency can be 0.1Hz. When the operating frequency of the compressor is the minimum frequency, the energy consumption of the compressor can be minimized.
在本实施例中，可以在室内安装温度传感器以检测室内的环境温度，并且将空调器与该温度传感器的信号输出端连接，当需要获取室内的环境温度时，空调器接收该温度传感器的输出信号即可。上述设定温度为用户所设置的期望温度，可以为用户通过遥控器或者空调器的控制面板所设置的温度值，该温度值通常可以显示在空调器面板上，如果空调器处于市电供电模式，则空调器会按照该温度值控制空调器，将室内环境的温度调节到设定温度，以满足用户对温度控制的需求。在本实施例中，可以通过读取用户通过遥控器或者空调器所输入的数据，以得到设定温度值。In this embodiment, a temperature sensor can be installed indoors to detect the indoor ambient temperature, and the air conditioner is connected to the signal output end of the temperature sensor. When the indoor ambient temperature needs to be obtained, the air conditioner receives the output signal of the temperature sensor. The above-mentioned set temperature is the desired temperature set by the user, which can be the temperature value set by the user through the remote control or the control panel of the air conditioner. The temperature value can usually be displayed on the air conditioner panel. If the air conditioner is in the mains power supply mode, the air conditioner will control the air conditioner according to the temperature value, and adjust the temperature of the indoor environment to the set temperature to meet the user's demand for temperature control. In this embodiment, the set temperature value can be obtained by reading the data input by the user through the remote control or the air conditioner.
步骤S3：如果室内的环境温度和设定温度满足预设条件，则控制内机风扇至低风模式；否则，控制内机风扇至自动风模式，并调整设定温度至满足预设条件。Step S3: If the indoor ambient temperature and the set temperature meet the preset conditions, the indoor fan is controlled to the low wind mode; otherwise, the indoor fan is controlled to the automatic wind mode and the set temperature is adjusted to meet the preset conditions.
在本实施例中，低风模式是空调器的内机风扇按照设定风速运行的模式，该设定风速可以由用户设置或者在生产时由工作人员设置并存储在空调器中，当空调器需要内机风扇工作在低风模式时，读取该设定风速并根据该设定风速运行即可。自动风模式是指内机风扇的转速根据室内的环境温度进行自动反馈调解，例如，当空调器启动制热模式时，室内的环境温度越低，内机风扇的转速越大；当空调启动制冷模式时，室内的环境温度越高，内机风扇的转速越大。In this embodiment, the low wind mode is a mode in which the indoor fan of the air conditioner operates at a set wind speed. The set wind speed can be set by the user or by the staff during production and stored in the air conditioner. When the air conditioner requires the indoor fan to operate in the low wind mode, the set wind speed is read and the air conditioner operates according to the set wind speed. The automatic wind mode refers to the automatic feedback adjustment of the speed of the indoor fan according to the indoor ambient temperature. For example, when the air conditioner starts the heating mode, the lower the indoor ambient temperature, the higher the speed of the indoor fan; when the air conditioner starts the cooling mode, the higher the indoor ambient temperature, the higher the speed of the indoor fan.
当室内的环境温度和设定温度满足预设条件时，可以认为室内的环境温度与用户设置的设定温度之间相差较小，此时控制内机风扇至低风模式，即可将室内的环境温度调节到用户预期的温度；反之，当室内的环境温度和设定温度不满足预设条件时，可以认为室内的环境温度与用户设置的设定温度之间相差较大，此时需要控制内机风扇至自动风模式，以对室内的环境温度的调节，提高室内环境的舒适度。When the indoor ambient temperature and the set temperature meet the preset conditions, it can be considered that the difference between the indoor ambient temperature and the set temperature set by the user is small. At this time, the indoor fan can be controlled to the low wind mode to adjust the indoor ambient temperature to the temperature expected by the user. On the contrary, when the indoor ambient temperature and the set temperature do not meet the preset conditions, it can be considered that the difference between the indoor ambient temperature and the set temperature set by the user is large. At this time, it is necessary to control the indoor fan to the automatic wind mode to adjust the indoor ambient temperature and improve the comfort of the indoor environment.
综上所述，本申请所提供的技术方案，通过入户灯的熄灭和亮起准确地判断出空调器是否处于市电供电状态，无需工作人员操作遥控器发送信号， 从而保证空调器的节能模式启动的可靠性。并且在节能模式启动时，仅响应空调器启动制冷功能或制热功能，并且将压缩机的运行频率调整到最低频率，因此可以减少空调器的能耗。另外，本申请的技术方案还根据室内的环境温度和设定温度控制内机风扇的工作模式，以对室内的环境温度进行调节，从而提高室内环境的舒适度。In summary, the technical solution provided by the present application can accurately determine whether the air conditioner is in the mains power supply state by turning off and on the entrance light, without the need for the staff to operate the remote control to send a signal. Thus, the reliability of the energy-saving mode startup of the air conditioner is ensured. When the energy-saving mode is started, only the cooling function or the heating function of the air conditioner is started, and the operating frequency of the compressor is adjusted to the lowest frequency, so that the energy consumption of the air conditioner can be reduced. In addition, the technical solution of the present application also controls the working mode of the indoor fan according to the indoor ambient temperature and the set temperature to adjust the indoor ambient temperature, thereby improving the comfort of the indoor environment.
在一个实施例中，上述预设条件包括：In one embodiment, the above-mentioned preset conditions include:
当空调启动制冷功能时，室内的环境温度小于第一温度阈值，或者室内的环境温度大于第一温度阈值且设定温度不小于目标温度；When the air conditioner starts the cooling function, the indoor ambient temperature is lower than the first temperature threshold, or the indoor ambient temperature is higher than the first temperature threshold and the set temperature is not lower than the target temperature;
当空调启动制热功能时，室内的环境温度大于第二温度阈值，或者室内的环境温度小于第二温度阈值且设定温度不大于目标温度。When the air conditioner starts the heating function, the indoor ambient temperature is greater than the second temperature threshold, or the indoor ambient temperature is less than the second temperature threshold and the set temperature is not greater than the target temperature.
上述目标温度可以为预先设置在空调器内的温度值，例如，该温度值可以为25℃，以满足人体舒适度对室内的环境温度的需求，当需要获取目标温度时，可以采用数据读取的方式读取存储的温度值，将该存储的温度值作为目标温度即可。The above-mentioned target temperature can be a temperature value pre-set in the air conditioner. For example, the temperature value can be 25°C to meet the human comfort requirements for the indoor ambient temperature. When the target temperature needs to be obtained, the stored temperature value can be read by data reading, and the stored temperature value can be used as the target temperature.
在本实施例中，上述第一温度阈值和第二温度阈值可以预先设置并存储在空调器中，例如第一温度阈值可以为30℃，第二温度阈值可以为18℃。In this embodiment, the first temperature threshold and the second temperature threshold may be pre-set and stored in the air conditioner. For example, the first temperature threshold may be 30° C., and the second temperature threshold may be 18° C.
在空调启动制冷功能时，如果室内的环境温度小于30℃，或者室内的环境温度大于30℃且设定温度不小于25℃时，可以认为室内的环境温度和设定温度满足预设条件，此时控制空调器的内机风扇至低风模式，以减少空调器的能耗。When the air conditioner starts the cooling function, if the indoor ambient temperature is less than 30℃, or the indoor ambient temperature is greater than 30℃ and the set temperature is not less than 25℃, it can be considered that the indoor ambient temperature and the set temperature meet the preset conditions. At this time, the indoor fan of the air conditioner is controlled to low wind mode to reduce the energy consumption of the air conditioner.
在空调启动制热功能时，如果室内的环境温度大于18℃，或者室内的环境温度小于18℃且设定温度小于25℃时，可以认为室内的环境温度和设定温度满足预设条件，此时控制空调器的内机风扇至低风模式，以减少空调器的能耗。When the air conditioner starts the heating function, if the indoor ambient temperature is greater than 18°C, or the indoor ambient temperature is less than 18°C and the set temperature is less than 25°C, it can be considered that the indoor ambient temperature and the set temperature meet the preset conditions. At this time, the indoor fan of the air conditioner is controlled to low wind mode to reduce the energy consumption of the air conditioner.
在一个实施例中，当空调器启动制冷功能时，调整设定温度至满足预设条件包括：按照预设温度步长周期性地增加设定温度，直到设定温度与目标温度相等；当空调器启动制热功能时，调整设定温度至满足预设条件包括：按照预设温度步长周期性地减小设定温度，直到设定温度与目标温度相等。In one embodiment, when the air conditioner starts the cooling function, adjusting the set temperature to meet the preset conditions includes: periodically increasing the set temperature according to the preset temperature step until the set temperature is equal to the target temperature; when the air conditioner starts the heating function, adjusting the set temperature to meet the preset conditions includes: periodically reducing the set temperature according to the preset temperature step until the set temperature is equal to the target temperature.
在一个实施例中，当空调器启动制冷功能时，如果室内的环境温度小于第一温度阈值，则将设定温度的值修改为目标温度的值；当空调器启动制热功能时，如果室内的环境温度大于第二温度阈值，则将设定温度的值修改为 目标温度的值。In one embodiment, when the air conditioner starts the cooling function, if the indoor ambient temperature is lower than the first temperature threshold, the set temperature value is modified to the target temperature value; when the air conditioner starts the heating function, if the indoor ambient temperature is higher than the second temperature threshold, the set temperature value is modified to The target temperature value.
例如，当空调器启动制冷功能时，如果室内的环境温度小于30℃，则无论设定温度的值为多少，均将设定温度的值修改为25℃；相应地，当空调器启动制热功能时，如果室内的环境温度大于18℃，则无论设定温度的值为多少，均将设定温度的值修改为25℃。通过本实施例的设置方式，可以在室内的环境温度与目标温度相差较小时，将目标温度作为设定温度，以在消耗较少能量的情况下，提高室内环境的舒适度。For example, when the air conditioner starts the cooling function, if the indoor ambient temperature is less than 30°C, the set temperature value is modified to 25°C regardless of the set temperature value; correspondingly, when the air conditioner starts the heating function, if the indoor ambient temperature is greater than 18°C, the set temperature value is modified to 25°C regardless of the set temperature value. Through the setting method of this embodiment, when the difference between the indoor ambient temperature and the target temperature is small, the target temperature can be used as the set temperature, so as to improve the comfort of the indoor environment while consuming less energy.
在本实施例中，以第一温度阈值是30℃、第二温度阈值是18℃、目标温度是25℃为例，当空调器启动制冷功能时，如果室内的环境温度大于30℃且设定温度小于25℃，则每间隔设定周期增加一次设定温度的值，该设定周期可以为30分钟，设定温度可以每次增加1℃，直到设定温度等于25℃，并且控制内机风扇的运行模式为自动风模式。当空调器启动制热功能时，如果室内的环境温度小于18℃且设定温度大于25℃，则每间隔设定周期减少一次设定温度的值，该设定周期可以为30分钟，设定温度可以每次减小1℃，直到设定温度等于25℃，并且控制内机风扇的运行模式为自动风模式。In this embodiment, taking the first temperature threshold value of 30°C, the second temperature threshold value of 18°C, and the target temperature of 25°C as an example, when the air conditioner starts the cooling function, if the indoor ambient temperature is greater than 30°C and the set temperature is less than 25°C, the set temperature value is increased once every set period, the set period can be 30 minutes, the set temperature can be increased by 1°C each time until the set temperature is equal to 25°C, and the operation mode of the indoor fan is controlled to be the automatic wind mode. When the air conditioner starts the heating function, if the indoor ambient temperature is less than 18°C and the set temperature is greater than 25°C, the set temperature value is reduced once every set period, the set period can be 30 minutes, the set temperature can be reduced by 1°C each time until the set temperature is equal to 25°C, and the operation mode of the indoor fan is controlled to be the automatic wind mode.
通过本实施例的设置方式，可以将室内的环境温度调解到目标温度，不仅可以提高室内环境的舒适度，而且可以防止设定温度的值过大或者过小而造成空调器的能耗过大。Through the setting method of this embodiment, the indoor ambient temperature can be adjusted to the target temperature, which can not only improve the comfort of the indoor environment, but also prevent the set temperature value from being too high or too low, causing excessive energy consumption of the air conditioner.
在一个实施例中，上述步骤S2中调整压缩机的运行频率至最低频率的流程如图2所示，包括：In one embodiment, the process of adjusting the operating frequency of the compressor to the minimum frequency in the above step S2 is shown in FIG2 , and includes:
步骤S21：判断压缩机的运行频率是否大于设定频率阈值；Step S21: determining whether the operating frequency of the compressor is greater than a set frequency threshold;
步骤S22：如果是，则将压缩机的频率降频到预设频率，然后按照设定频率步长降频到最低频率。Step S22: If yes, the frequency of the compressor is reduced to a preset frequency, and then reduced to a minimum frequency according to a set frequency step.
在本实施例中，上述预设频率可以为压缩机的额定频率，例如可以为50Hz，设定频率步长可以根据需求进行设置。上述设定频率阈值为大于压缩机额定频率的频率值，当压缩机的运行频率大于设定频率阈值时，可以认为压缩机高频运行，此时先将压缩机的频率降频到预设频率，即降频到压缩机的额定频率，然后再逐步降低压缩机的频率，每次下降的均为设定频率步长，直到压缩机的频率为最低频率。本实施例的设置方式不仅可以降低空调器的能耗，还能够防止压缩机的频率下降过快而影响空调器的正常运行。In this embodiment, the preset frequency may be the rated frequency of the compressor, for example, 50 Hz, and the set frequency step may be set as required. The set frequency threshold is a frequency value greater than the rated frequency of the compressor. When the operating frequency of the compressor is greater than the set frequency threshold, it can be considered that the compressor is operating at a high frequency. At this time, the frequency of the compressor is first reduced to the preset frequency, that is, reduced to the rated frequency of the compressor, and then the frequency of the compressor is gradually reduced, each time by the set frequency step, until the frequency of the compressor is the lowest frequency. The setting method of this embodiment can not only reduce the energy consumption of the air conditioner, but also prevent the frequency of the compressor from decreasing too quickly and affecting the normal operation of the air conditioner.
在一个实施例中，本申请的空调器的控制方法还包括：当室内达到设定 温度时，控制感温器停止工作。在本实施例中，感温器可以为设置在空调器内机上的温度传感器，用于检测室内的环境温度，并且空调器可以对感温器的工作状态进行控制。例如，本实施例的空调器中，可以由空调器的主控板连接感温器的电源端，采用空调器的主板为感温器供电。当室内温度达到设定温度时，停止向感温器供电以使感温器停止工作，从而减少感温器所消耗的电能，提高备用电源的续航能力。In one embodiment, the control method of the air conditioner of the present application further includes: when the indoor temperature reaches a set value When the indoor temperature reaches the set temperature, the temperature sensor is controlled to stop working. In this embodiment, the temperature sensor may be a temperature sensor provided in the air conditioner, which is used to detect the indoor ambient temperature, and the air conditioner may control the working state of the temperature sensor. For example, in the air conditioner of this embodiment, the main control board of the air conditioner may be connected to the power supply end of the temperature sensor, and the main board of the air conditioner may be used to power the temperature sensor. When the indoor temperature reaches the set temperature, the power supply to the temperature sensor is stopped so that the temperature sensor stops working, thereby reducing the power consumed by the temperature sensor and improving the endurance of the backup power supply.
在一个实施例中，本申请的空调器的控制方法，在室内环境达到设定温度时，还包括如图3所示的对内机风扇的控制的流程，该流程包括：In one embodiment, the control method of the air conditioner of the present application further includes a process of controlling the indoor fan as shown in FIG3 when the indoor environment reaches the set temperature. The process includes:
步骤S31：当室内环境达到设定温度时，控制内机风扇按照低风模式工作并开始计时；Step S31: When the indoor environment reaches the set temperature, the indoor fan is controlled to operate in low wind mode and timing starts;
步骤S32：当内机风扇的工作时长达到第一预设时长时控制内机风扇停机。Step S32: When the working time of the indoor fan reaches a first preset time, the indoor fan is controlled to stop.
在本实施例中，第一预设时长可以为50秒，即当室内温度达到设定温度后，控制内机风扇进行低风模式并开始计时，该计时可以由空调器的计时器实现，当计时的时长达到50秒时，控制内机风扇停机，以减少内机风扇的耗电量。In this embodiment, the first preset time length can be 50 seconds, that is, when the indoor temperature reaches the set temperature, the indoor fan is controlled to enter the low wind mode and starts timing. The timing can be achieved by the timer of the air conditioner. When the timing reaches 50 seconds, the indoor fan is controlled to stop to reduce the power consumption of the indoor fan.
进一步地，在另一个实施例中，可以在室内换热器的盘管处设置温度传感器，以检测室内换热器的盘管的温度。当空调器启动制热功能时，在室内环境达到设定温度并且控制内机风扇按照低风模式工作的第一预设时长内，通过室内换热器的盘管处的温度传感器检测室内换热器的盘管的温度，并判断该温度是否小于设温度阈值，该设定温度阈值小于目标温度，例如，可以采用23℃。当室内换热器的盘管的温度小于设定温度阈值时控制内机风扇停机，以防止室内的温度降低。Furthermore, in another embodiment, a temperature sensor may be provided at the coil of the indoor heat exchanger to detect the temperature of the coil of the indoor heat exchanger. When the air conditioner starts the heating function, the temperature of the coil of the indoor heat exchanger is detected by the temperature sensor at the coil of the indoor heat exchanger within the first preset time when the indoor environment reaches the set temperature and the indoor fan is controlled to work in the low wind mode, and it is determined whether the temperature is less than a set temperature threshold, and the set temperature threshold is less than the target temperature, for example, 23°C may be used. When the temperature of the coil of the indoor heat exchanger is less than the set temperature threshold, the indoor fan is controlled to stop to prevent the indoor temperature from decreasing.

When the air conditioner is in energy-saving mode, it is determined whether the air conditioner receives a control signal input by the user. The control signal can be a signal input by the user through a remote control or a signal input by the user through the control panel of the air conditioner. When the air conditioner receives a control signal, the air conditioner identifies the control signal to determine whether the control signal is a start signal or a shutdown signal. If not, it does not respond to the user's operation and controls the air conditioner display screen to display preset words, such as "energy-saving operation", to remind the user that the air conditioner is in energy-saving mode. In order to reduce the energy consumption of the air conditioner display screen. The timing starts when the preset words are displayed on the display screen. When the timing reaches the second preset time length, if no signal is received, the air conditioner will be reset. Control signal, then the air conditioner display screen will be turned off.
