空调属于耗电量较大的家用电器，因此就要求空调可以按照电网的需求进行自动的调整耗电情况。目前澳大利亚政府已经明确要求，自2015年开始，要求空调设备能够按照电力公司发出的抑制信号，实现对于空调耗电能力的控制。而目前市面上的空调存在以下问题：Air conditioners are household appliances that consume a lot of power, so it is required that the air conditioner can automatically adjust the power consumption according to the needs of the power grid. At present, the Australian government has clearly requested that, starting from 2015, air-conditioning equipment should be able to control the power consumption of air-conditioning in accordance with the suppression signal issued by the power company. The air conditioners currently on the market have the following problems:
(1)目前市面上的空调基本都会有无源信号接收端口，从理论上都可以在接收到无源信号时，实现空调直接关机；但是如果要实现按照百分比耗电水平输出，目前的硬件装置以及处理方法都无法实现；(1) At present, the air conditioners on the market basically have passive signal receiving ports. In theory, when receiving a passive signal, the air conditioner can be directly shut down; but if the output is to be output according to the percentage of power consumption, the current hardware device and processing methods are not available;
(2)目前国内部分地区已经实行分时电价，用户无法通过对空调的简单设置在用电高峰时自动降低空调机组的耗电。(2) At present, time-of-use electricity prices have been implemented in some areas of the country, and users cannot automatically reduce the power consumption of air-conditioning units during peak power consumption through simple settings for air-conditioning.

下面结合附图并通过具体实施方式来进一步说明本发明的技术方案。The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.
本发明提出了一种空调机组的控制方法，空调机组接收来自外部的电力抑制信号，并根据电力抑制信号进行以下操作的一种或多种操作，所述操作包括：降低室外机压缩机的工作频率，改变室内机的设定参数，关闭至少一台室内机，通过上述操作可以降低空调机组的功耗，以满足电力抑制要求。The present invention proposes a control method for an air-conditioning unit. The air-conditioning unit receives an external power suppression signal, and performs one or more of the following operations according to the power suppression signal. The operations include: reducing the work of the outdoor unit compressor Frequency, change the setting parameters of the indoor unit, and turn off at least one indoor unit. Through the above operations, the power consumption of the air conditioning unit can be reduced to meet the power suppression requirements.
本发明提供的控制方法能够自动响应智能电网的电力抑制信号，实现对空调机组的智能控制，节能环保。The control method provided by the invention can automatically respond to the power suppression signal of the smart grid, realize the intelligent control of the air-conditioning unit, and save energy and protect the environment.
实施例一：Embodiment one:
如图1所示，本实施例提供的空调机组包括室外机1、多个室内机2以及控制装置，控制装置包括控制单元3、电流电压采集单元4以及通讯单元5。通讯单元5与空调机组的电源线相连，用于接收智能电网发出的电力抑制信号并将电力抑制信号传输至控制单元3。电流电压采集单元4可采集空调机组的电压和电流信号并将其传输至控制单元3。控制单元3可根据电压和电流信号计算获得空调机组的功耗，并结合电力抑制信号对空调机组的室外机1和室内机2进行控制。As shown in FIG. 1 , the air conditioning unit provided in this embodiment includes an outdoor unit 1 , multiple indoor units 2 and a control device, and the control device includes a control unit 3 , a current and voltage acquisition unit 4 and a communication unit 5 . The communication unit 5 is connected to the power line of the air conditioning unit, and is used for receiving the power suppression signal sent by the smart grid and transmitting the power suppression signal to the control unit 3 . The current and voltage collection unit 4 can collect the voltage and current signals of the air conditioning unit and transmit them to the control unit 3 . The control unit 3 can calculate the power consumption of the air conditioning unit according to the voltage and current signals, and control the outdoor unit 1 and the indoor unit 2 of the air conditioning unit in combination with the power suppression signal.
其中的电力抑制信号可以为停止耗电信号，也可以是电力消耗抑制比信号。若为停止耗电信号，则控制单元3控制关闭所有的室内机2，空调机组停止运转，实现零耗电。电力消耗抑制比为空调机组的目标功耗与初始功耗之比，例如，若接收的电力消耗抑制比信号为70％，则控制单元3控制空调机组的功耗降为原功耗的70％。另外，电力抑制信号也可以为一个范围值，即电力消耗抑制比范围信号，电力消耗抑制比范围的最小值为空调机组的最小目标功耗与初始功耗之比，电力消耗抑制比范围的最大值为空调机组的最大目标功耗与初始功耗之比，此时，则需要控制单元3控制空调机组的功耗落在目标功耗范围内，例如，接收的电力消耗抑制比范围信号为50％-70％，则控制单元3控制空调机组的功耗降为原功耗的50％-70％即可。The power suppression signal may be a power consumption stop signal, or a power consumption suppression ratio signal. If it is a signal to stop power consumption, the control unit 3 controls to turn off all the indoor units 2, and the air conditioner unit stops running, so as to realize zero power consumption. The power consumption suppression ratio is the ratio of the target power consumption of the air conditioning unit to the initial power consumption. For example, if the received power consumption suppression ratio signal is 70%, the control unit 3 controls the power consumption of the air conditioning unit to drop to 70% of the original power consumption . In addition, the power suppression signal can also be a range value, that is, the power consumption suppression ratio range signal. The minimum value of the power consumption suppression ratio range is the ratio of the minimum target power consumption to the initial power consumption of the air conditioning unit, and the maximum value The value is the ratio of the maximum target power consumption of the air-conditioning unit to the initial power consumption. At this time, the control unit 3 is required to control the power consumption of the air-conditioning unit to fall within the target power consumption range. For example, the received power consumption suppression ratio range signal is 50 %-70%, then the control unit 3 can control the power consumption of the air-conditioning unit to be reduced to 50%-70% of the original power consumption.
