- the control method for the air conditioning system of this embodiment includes:
- Step 110 Receive a request to reduce energy consumption.
- the air conditioning system may receive a request to reduce energy consumption when operating normally. It can be understood as a request to reduce power consumption, which can be a request issued by the cloud platform (such as the power grid) based on energy consumption scheduling.
- the request to reduce energy consumption includes but is not limited to the target value for the current whole machine power reduction, the limiting control information of the electric auxiliary heating device, the comfort control index, or the current energy consumption response level and the above information contained in the level. However, it should at least include the target value for the whole machine power reduction or relevant information that can be used to calculate the value.

- the comfort parameter can be the indoor air quality parameter.
- the comfort parameter of the air conditioner system in the current operation state can be obtained through the relevant sensors of the air conditioner system.

Specifically, the energy consumption reduction request may directly represent the target power, or the target power required for the air-conditioning system to operate as required by the energy consumption reduction request may be deduced through relevant parameters.
- the target power required for the air-conditioning system to operate as required by the energy consumption reduction request is the target power corresponding to the energy consumption reduction request. If the air-conditioning system operates according to the target power, the energy consumption reduction request can be met and the expected energy consumption reduction effect can be achieved.
- Step 102 Determine whether the current operating power of the air-conditioning system is less than or equal to the target power corresponding to the energy consumption reduction request. If yes, execute step 103; if not, execute step 104.
- Step 103 According to the current operating power being less than or equal to the target power corresponding to the energy consumption reduction request, the preset comfort control operation is maintained.
- the preset comfort control operation is a control operation for the normal operation of the air conditioning system, which can be understood as the operation of the air conditioning system operating without receiving or responding to a request to reduce energy consumption.
- the preset comfort control operation can be preset in In the controller of the air conditioning system, under the preset comfort control operation, the air conditioning system can automatically adjust the comfort parameters to the range set or required by the user.
- the current operating power is less than or equal to the target power corresponding to the energy consumption reduction request, it means that the current operating state of the air-conditioning system can meet the demand for reducing energy consumption, so the air-conditioning system can maintain the preset comfort control operation without adjustment.
- Step 104 According to the current operating power being greater than the target power corresponding to the energy consumption reduction request, a step of obtaining comfort parameters of the air-conditioning system in the current operating state is performed.
- the current operating power is greater than the target power corresponding to the energy consumption reduction request, it means that the current operating state of the air-conditioning system cannot meet the demand for reducing energy consumption. At this time, it is necessary to determine whether to adjust the current operating power based on the comfort parameters under the current operating state.
- step 130 controls the operation of the air conditioning system according to the comfort parameter, which may include steps 1301 and 1302.

- the air conditioning system is made to perform the energy-saving control operation, and it can also include reducing the power of the electric auxiliary heating device of the air conditioning system according to the current operating state of the air conditioning system being a heating condition.
- reducing the current operating frequency of the air-conditioning system may specifically reduce the power of the air-conditioning system by reducing the preset frequency at preset intervals.
- Reducing the current operating frequency of the air-conditioning system may include reducing the current operating frequency of the air-conditioning system to zero, that is, shutting down the air-conditioning.
- reducing the power of the electric radiation device may include shutting down the electric radiation device.
- the frequency of one component may be adjusted first, so that the frequencies of other components remain constant.
- the operating frequency of the air-conditioning system remains unchanged to improve the convenience of controlling the reduction of the current operating frequency of the air-conditioning system. For example, only the operating frequency of the compressor can be adjusted, and the operating frequency of the outdoor fan and the operating frequency of the indoor fan are not adjusted.
- the air-conditioning system in response to a request to reduce energy consumption, can perform a preset comfort control operation based on the comfort parameters of the air-conditioning system in the current operating state exceeding the target parameter range, and can perform an energy reduction control operation based on the comfort parameters being within the target parameter range.
- the air-conditioning system can reduce energy consumption on the basis of satisfying comfort, so that the air-conditioning system can take into account both comfort and peak-shifting electricity consumption needs, alleviating the problem of reduced comfort caused by the air-conditioning system power being reduced only according to the peak-shifting demand index.
- step 1301 according to the comfort parameter exceeding the target parameter range, the air conditioning system is caused to perform a preset comfort control operation, as shown in FIG4 , specifically including:
- Step 111 According to the comfort parameter being worse than the first limit value, the air conditioning system is enabled to perform a preset comfort control operation.

- the first limit value is inferior to the second limit value.
- the first limit value and the second limit value are both preset comfort parameters, which can be information in the energy consumption reduction request or parameters pre-stored in the controller of the air conditioning system.
- the quality of the comfort parameter is based on the user's expectation of the current operation mode.
- the comfort parameter is inferior to the first limit value, including: in the cooling mode, the comfort parameter is greater than the first limit value; in the heating mode, the comfort parameter is less than the first limit value.

- the first limit value can be different values, that is, according to different operation modes, the corresponding first limit value is set; similarly, the second limit value is set according to the operation mode and the first limit value.
- the first limit value is different from the second limit value, which can reduce the probability of the air-conditioning system fluctuating back and forth between the energy consumption reduction control operation and the preset comfort control operation near the critical value, which is beneficial to the stable operation of the air-conditioning system.
- the air conditioning system After responding to the energy reduction request, the air conditioning system can detect the comfort parameters of the current operating state in real time during the energy reduction request time. As the air conditioning system continues to operate, the comfort parameters of the air conditioning system will also change. In order to make the air conditioning system better balance comfort and energy consumption, in some embodiments, as shown in FIG5 , the control method of the air conditioning system includes:

If the electric auxiliary heating device is turned on, the electric auxiliary heating device is turned off. If the electric auxiliary heating device is not turned on, the step of controlling the compressor to reduce the operating frequency is performed. It is understandable that when the compressor is in the heating mode, if the external ambient temperature is too low and only turning on the compressor cannot meet the heating demand, the electric auxiliary heating device needs to be turned on to increase the heat output of the air conditioning system. However, the electric auxiliary heating device converts electrical energy into thermal energy for heating. There is a resistance wire inside the electric auxiliary heating device. After power is turned on, the electrical energy is converted into thermal energy and transmitted to the room.

- the gear of the outdoor fan is positively correlated with the operating frequency. Specifically, when the operating frequency of the compressor is high, the cooling or heat output of the air-conditioning system is high, and therefore, the heat exchange amount required by the outdoor heat exchanger is large, so the outdoor fan is set at a high gear to improve the heat exchange efficiency of the outdoor heat exchanger; when the operating frequency of the compressor is low, the cooling or heat output of the air-conditioning system is low, and therefore, the heat exchange amount required by the outdoor heat exchanger is small, so the gear of the outdoor fan is reduced to make the outdoor fan at a low gear, and the current operating power of the air-conditioning system is reduced while meeting the heat exchange demand of the outdoor heat exchanger.

空调系统也称为空调器,其可以是家用空调,也可以是中央空调,空调系统的空调机组包括室内机和室外机,室内机包括室内换热器,室内机通常安装在室内,室外机包括室外换热器,室外机通常安装在室外,室内机和室内机共同配合工作,以实现空调系统的制冷、制热、除湿以及净化空气等作用,以达到舒适的空气质量。
在中央空调的空调机组中,室外机通常为一个,而室内机的数量可以为多个,各室内机上设有一个或多个出风口,以将制冷、制热、除湿或者净化后的空气经出风口排放至室内。室内机中通常设置有室内换热器,室外机中通常设置有室外换热器,室内换热器和室外换热器通常通过冷媒管道连通,使得室内换热器和室外换热器之间的冷媒可以流通。
空调系统在制冷过程中,室内换热器为蒸发器,蒸发器中的冷媒从液体吸热变为气态,在冷媒蒸发吸热的过程中,蒸发器与流过蒸发器的空气进行热交换,将室内机中的空气中
的热量带走,进而使得排出室内机的空气为放热降温后的空气,室内机吹冷风,同时,室外换热器为冷凝器,冷凝器中的冷媒从气态变为液态,在冷媒冷凝放热的过程中,冷凝器与流过冷凝器的室外机中空气进行热交换,使得室外机中的空气将冷凝器的热量带到室外机外部,实现制冷过程。
空调系统在制热过程中,室外换热器为蒸发器,蒸发器中的冷媒从液态吸热变为气态,在冷媒蒸发吸热的过程中,蒸发器与流过蒸发器的空气进行热交换,将室外机中的空气中携带的热量置换到蒸发器内的冷媒中,同时,室内换热器为冷凝器,冷凝器中的冷媒从气态变为液态,在冷媒冷凝放热的过程中,冷凝器与流过冷凝器的室内机中的空气进行热交换,使得室内机中的空气将冷凝器携带的热量带走,并从室内机排放到室内机外的室内,使得室内机吹热风,如此,实现制热过程。
在空调系统中,还包括压缩机、节流部件(例如膨胀阀)等,为了降低室内噪音,压缩机、节流部件通常可以设置在室外,压缩机、节流部件和室外换热器等这些设置在室外的构件,可以统称为室外机组。在空调系统既可以制冷又可以制热的情况下,空调系统还包括四通阀等零件,以实现空调系统在制冷模式和制热模式的切换。
需要注意的是,空调系统可以是室外机和室内机分体设置的结构,也可以是内室外机一体式结构,在空调系统为内室外机一体式结构的情况,可以将整体空调系统均设置在室外。
空调系统还可以包括与外部通讯的网关,可以接收外部的命令、请求及其他控制目标参数等。
随着碳中和的普及及空调节能运行的日益增长,电网错峰响应的需求越来越高。对于空调设备而言,在错峰响应过程中,一个比较困难的点在于平衡舒适性与需求响应之间的机组控制问题。在一些技术中,通常是按照错峰需求指标去对空调系统的室内机的设定温度、室外机输出进行控制,而其结果必然会导致舒适性的下降。基于此,如何解决在保证机组舒适性前提下,响应错峰需求的机组控制问题,是一个亟待解决的问题。
本公开实施例提出一种空调系统的控制方法,以缓解空调系统仅按照错峰需求指标降低空调系统功率导致舒适性下降的问题。如图1所示,本实施例空调系统的控制方法,包括:
步骤110:接收降低能耗请求。
其中,空调系统可以是在正常运行的情况下,接收降低能耗请求。降低能耗请求
可理解为降低电量请求,其可以是云平台(例如电网)基于耗能调度发出的请求,降低能耗请求中,包括但不限于包含要求当前整机功率下降的目标值、电辅热装置的限制控制信息、舒适度控制指标,或当前能耗响应等级及等级内包含的上述信息。但至少应包含整机功率下降的目标值或可以推算出该值的相关信息。
步骤120:根据降低能耗请求,获取所述空调系统在当前运行状态下的舒适度参数。
舒适度参数也即是空调当前运行模式下,用户所期望的参数,具体的,在空调系统处于制冷模式或制热模式下,舒适度参数可以是室内温度参数;在空调系统处于除湿模式下,舒适度参数可以是室内的湿度参数;在空调系统处于净化模式下,舒适度参数可以是室内的空气质量参数。空调系统在当前运行状态下的舒适度参数可以通过空调系统的相关传感器获得,例如,空调系统处于制冷模式或制热模式下,可以通过室内机的温度传感器获得室内温度参数。
步骤130:根据所述舒适度参数,控制所述空调系统运行。
根据实施例空调系统的控制方法,在接收到降低能耗请求后,空调系统会结合舒适度参数执行运行程序,也就是说,舒适度参数是空调系统接收到降低能耗请求时的一个参考条件,这样可以使得空调系统在接收到降低能耗请求时,兼顾考虑舒适度,缓解了空调系统仅按照错峰需求指标降低空调系统功率导致舒适性下降的问题。可选的,在一些实施例中,在接收到降低能耗请求的情况下,也可以先对空调系统的当前运行功率进行判断,即如图3所示,所述空调系统的控制方法还包括:
步骤101:响应于降低能耗请求,获取空调系统的当前运行功率。
其中,降低能耗请求可以表征所要求空调系统运行的目标功率,具体的,可以是降低能耗请求直接表征目标功率,也可以是通过相关参数,可以推出降低能耗请求所要求空调系统运行的目标功率。降低能耗请求所要求空调系统运行的目标功率,也即是降低能耗请求所对应的目标功率,若空调系统按照该目标功率运行可以满足降低能耗请求的需求,达到预期的降低能耗的效果。
步骤102:判断空调系统的当前运行功率是否小于等于降低能耗请求所对应的目标功率,如果是,执行步骤103,如果否,执行步骤104。
步骤103:根据当前运行功率小于或等于降低能耗请求对应的目标功率,保持预设舒适度控制操作运行。
预设舒适度控制操作是空调系统正常运行的控制操作,可以理解为空调系统在不接收或不响应降低能耗请求的状况下运行的操作。预设舒适度控制操作可以是预设在
空调系统的控制器内的,在预设舒适度控制操作下,空调系统可以自动将舒适度参数调节至用户所设定或所需求的范围内。
在当前运行功率小于或等于降低能耗请求对应的目标功率的情况下,说明空调系统当前运行状态就可以满足降低能耗的需求,所以空调系统可保持预设舒适度控制操作不做调整。
步骤104:根据当前运行功率大于降低能耗请求对应的目标功率,执行获取空调系统在当前运行状态下的舒适度参数的步骤。
在当前运行功率大于降低能耗请求对应的目标功率的情况下,说明空调系统的当前运行状态不能满足降低能耗的需求,此时需要根据当前运行状态下的舒适度参数判断是否要进行当前运行功率的调整。
在一些实施例中,如图2和图3所示,步骤130根据所述舒适度参数,控制所述空调系统运行,可以包括步骤1301和步骤1302。步骤1301:根据舒适度参数超出目标参数范围,使空调系统执行预设舒适度控制操作。
目标参数范围可以是舒适度参数的目标参数范围,该目标参数范围可以是降低能耗请求中包括的规定值,即,云平台发出的降低能耗请求中包括了目标参数范围。目标参数范围也可以是空调系统的控制器内预设的一套控制值,即,空调系统的控制器内预设有目标参数范围。
步骤1302:根据舒适度参数处于目标参数范围内,使空调系统执行降能耗控制操作。
降能耗控制操作是能够使空调的运行功率降低的操作。具体的,使空调系统执行降能耗控制操作,包括:使空调系统的当前运行频率降低,空调系统的运行频率包括室外机的风机(即室外风机)的运行频率、空调系统的室内机的风机(室内风机)的运行频率和/或空调系统的压缩机的运行频率降低。在空调系统包括电辅热装置,且空调系统的当前运行模式是制热模式的情况下,使空调系统执行降能耗控制操作,还可以包括根据空调系统的当前运行状态为制热工况,使空调系统的电辅热装置的功率降低。
其中,使空调系统的当前运行频率降低,具体可以是使空调系统的运行频率按照每隔预设时间降低预设频率的方式降低功率。使空调系统的当前运行频率降低,可以包括将空调系统的当前运行频率降低至零的情况,也即使空调关机的情况。同理,使电辐射装置的功率降低可以包括将电辐射装置关闭的情况。在使空调系统的当前运行频率降低的情况下,可以先针对其中一个构件的频率进行调节,使其他构件的频率保
持不变,以提高对空调系统的当前运行频率降低的控制方便性,例如可以只调节压缩机的运行频率,室外风机的运行频率、室内风机的运行频率不做调整。
根据本实施例的空调系统的控制方法,在响应于时降低能耗请求,可以根据空调系统在当前运行状态下的舒适度参数超出目标参数范围,使空调系统执行预设舒适度控制操作,并可以根据舒适度参数处于目标参数范围内,使空调系统执行降能耗控制操作,这样空调系统可以在满足舒适度的基础上,降低能耗,使得空调系统可以兼顾舒适性与错峰用电的需求,缓解了空调系统仅按照错峰需求指标降低空调系统功率导致舒适性下降的问题。
在一个实施例中,步骤1301,根据舒适度参数超出目标参数范围,使空调系统执行预设舒适度控制操作,如图4所示,具体包括:
步骤111:根据舒适度参数劣于第一极限值,使空调系统执行预设舒适度控制操作。
步骤112:根据舒适度参数处于目标参数范围内,使空调系统执行降能耗控制操作,包括:根据舒适度参数优于第二极限值,使空调系统执行降能耗控制操作。
其中,第一极限值劣于第二极限值。第一极限值和第二极限值均为预设的舒适度的参数,其可以是降低能耗请求中的信息,也可以是预存在空调系统的控制器内的参数。
其中,舒适度参数的优劣以当前运行模式的用户期望为参照,比用户的期望越好,表示舒适度参数越优,比用户的期望越低,表示舒适度参数越劣。例如,在制冷模式下,温度越低越优,温度越高越劣;在制热模式下,温度越高越优,温度越低越劣。具体而言,舒适度参数劣于第一极限值,包括:在制冷模式下,舒适度参数大于第一极限值;在制热模式下,舒适度参数小于第一极限值。其中,在制冷模式和制热模式下,第一极限值可以为不同值,即根据不同的运行模式,设定相应的第一极限值。同理,第一极限值劣于第二极限值,包括:在制冷模式下,第一极限值大于第二极限值;在制热模式下,第一极限值小于第二极限值。其中,在制冷模式和制热模式下,第一极限值可以为不同值,即根据不同的运行模式,设定相应的第一极限值;同理,第二极限值根据运行模式和第一极限值进行设定。
第一极限值与第二极限值不同,可以降低空调系统在降能耗控制操作与预设舒适度控制操作之间在临界值附近往复变动的概率,有利于空调系统的稳定运行。
在响应于降低能耗请求后,在降低能耗请求的时间内,空调系统可以实时检测当前运行状态的舒适度参数。随着空调系统的不断运行,空调系统的舒适度参数也会变
化,为了使得空调系统可以更好的平衡舒适度与能耗,在一些实施例中,如图5所示,空调系统的控制方法包括:
步骤131:根据空调系统处于执行降能耗控制操作的状态,且舒适度参数劣于第三极限值,使空调系统进入第一状态,在第一状态空调系统维持当前运行状态。
其中,舒适度参数劣于第三极限值,包括:在制冷模式下,舒适度参数大于第三极限值;在制热模式下,舒适度参数小于第三极限值。
步骤132:根据空调系统处于第一状态,舒适度参数劣于第四极限值,执行使空调系统执行预设舒适度控制操作的步骤。其中,第四极限值劣于第三极限值,第四极限值劣于第一极限值或与第一极限值相同,第三极限值劣于第二极限值或与第二极限值相同。
其中,舒适度参数劣于第四极限值,包括:在制冷模式下,舒适度参数大于第四极限值;在制热模式下,舒适度参数小于第三极限值。第四极限值劣于第三极限值,包括:在制冷模式下,第四极限值大于第三极限值;在制热模式下,第四极限值小于第三极限值。第四极限值劣于第一极限值,包括,在制冷模式下,第四极限值大于第一极限值;在制热模式下,第四极限值小于第一极限值。第三极限值劣于第二极限值,包括:在制冷模式下,第三极限值大于第二极限值;在制热模式下,第三极限值小于第二极限值。
步骤133:根据空调系统处于执行预设舒适度控制操作的状态,且舒适度参数优于第五极限值,使空调系统进入第二状态,在第二状态空调系统维持当前运行状态。
其中,舒适度参数优于第五极限值,包括:在制冷模式下,舒适度参数小于第五极限值;在制热模式下,舒适度参数大于第五极限值。
步骤134:根据空调系统处于第二状态,舒适度参数优于第六极限值,使空调系统执行预设舒适度控制操作。第五极限值优于第一极限值或与第一极限值相同,第六极限值优于第五极限值,第六极限值优于第二极限值或与第二极限值相同。
其中,舒适度参数优于第六极限值,包括:在制冷模式下,舒适度参数小于第六极限值;在制热模式下,舒适度参数大于第六极限值。第五极限值优于第一极限值,包括在制冷模式下,第五极限值小于第一极限值;在制热模式下,第五极限值大于第一极限值。第六极限值优于第五极限值,包括:在制冷模式下,第六极限值小于第五极限值;在制热模式下,第六极限值大于第五极限值。第六极限值优于第二极限值,包括:在制冷模式下,第六极限值小于第二极限值;在制热模式下,第六极限值大于
第二极限值。
在一个实施例中,舒适度参数为温度参数,第四极限值与第三极限值之间的差值为第一差值CB1,第一差值CB1的取值可以在1℃至3℃之间,具体可以是1℃、2℃、3℃;第四极限值与第五极限值之间的差值为第二差值CA1,第二差值CA1的取值在可以0℃至2℃之间,具体可以是0、1℃、2℃;第四极限值与第六极限值之间的差值为第三差值CB2,第三差值CB2的取值在1℃至4℃之间,具体可以为是1℃、2℃、3℃、4℃。
如图9所示,以制冷模式为例,舒适度参数为室内房间实时温度,即室内环境温度T1,目标参数范围小于等于室内房间设定温度Ts,ΔT_DRcool为制冷舒适度允许容差,可以为2~5℃。当T1≥Ts+ΔT_DRcool即表示系统舒适度已经不满足需求,则这时候机组按照正常的舒适度控制,即执行预设舒适度控制操作。CA1、CB1、CB2为调节回差。CA1可以为0~2℃、CB1可以为1~3℃,CB2可以为1~4℃。当T1处于回差中间时,空调系统保持当前运行状态不变(即室外机压缩机、室外风机、室内风机等负载保持输出不变);而当T1处于底部区间时(下行阶段:T1<Ts+ΔT_DRcool-CB2;上行阶段:T1<Ts+ΔT_DRcool-CB1),空调系统可以执行降能耗控制。
需要说明的是,在响应于降低能耗请求,首次获取的室内房间实时温度后,可以默认空调系统处于执行预设舒适度控制的状态,即可以以空调系统处于执行预设舒适度控制的状态作为起点,进行降低能耗的控制。在制冷模式下,上行阶段指的是室内房间实时温度在空调系统的作用下不断升高的阶段;下行阶段指的是室内房间实时温度在空调系统的作用下不同降低的阶段。
如图10所示,在制热模式下,存在相似的控制,ΔT_DRheat为制热舒适度允许容差,可以的为2~5℃,HA1、HA2、HB1为调节回差。HA1可以为0~2℃、CB1可以为1~3℃,CB2可以为1~4℃。控制区间和操作过程与制冷模式相似,在此不再赘述。
其中,ΔT_DRcool与ΔT_DRheat可以为机器的预设值,也可以伴随着能耗响应命令由外部发送给空调系统。
需要说明的是,上述以制冷模式或制热模式所描述的具体方式,其他同类保证室内舒适度的控制也可以参照执行,如不以TS为目标,而是以当前实际室内人体感觉舒适的温湿度为目标,其中,温湿度为目标可由空调系统自身推断,也可以是由外部发送给空调系统。
在一些实施例中,步骤1032的使空调系统执行降能耗控制操作,如图6所示,包
括:
步骤141:根据降低能耗请求,确定空调系统的需求额定功率比例。
空调系统的需求额定功率可以是降低能耗请求需要使当前空调系统降低至的功率与空调系统额定功率的百分比,例如,需求额定功率可以是空调系统额定功率的70%
步骤142:基于空调系统的需求额定功率比例,控制空调系统执行降能耗控制操作。
以空调系统的需求额定功率比例作为能耗降低参照,可以保证在降能耗时,减少对电网的冲击(功率突降或突升)同时也能够更加自由的适应不同的能耗响应命令需求,减少指令复杂程度,节约网络通讯字节。
在一些实施例中,基于空调系统的需求额定功率比例,控制空调系统执行降能耗控制操作,如图7所示,包括:
步骤151:根据空调系统运行状态的当前运行功率超出需求额定功率的第一目标校准值,使空调系统执行降能耗控制操作。
步骤152:根据空调系统运行状态的当前运行功率低于第二目标校准值,使空调系统执行预设舒适度控制操作。
其中,第二目标校准值小于第一目标校准值,第二目标校准值和第一目标校准值是对需求额定功率进行校准后的设定值。
在空调系统响应降低能耗请求的过程中,空调系统的当前运行功率实时变化,为了兼顾舒适度和能耗请求。在本公开的一些实施例中,如图8所示,基于空调系统的需求额定功率比例,控制空调系统执行降能耗控制操作,包括:
步骤161:根据空调系统处于执行预设舒适度控制操作的状态,且当前运行功率超出需求额定功率的第三目标校准值,使空调系统进入第三状态,在第三状态,空调系统维持当前运行状态;
步骤162:根据空调系统处于第三状态,且当前运行功率超出需求额定功率的第四目标校准值,使空调系统执行降能耗控制操作。第三目标校准值与第二目标校准值相同或大于第二目标校准值,第四目标校准值与第一目标校准值相同或大于第一目标校准值。
步骤163:根据空调系统处于执行降能耗控制操作的状态,且当前运行功率低于需求额定功率的第五目标校准值,使空调系统进入第四状态,在第四状态,空调系统维持当前运行状态。
步骤164:根据空调系统处于第四状态,且当前运行功率低于需求额定功率的第六
目标校准值,使空调系统执行预设舒适度控制操作。第五目标校准值与第一目标校准值相同或小于第二目标校准值,第六目标校准值与第二目标校准值相同或低于第一目标校准值。
具体的,第三目标校准值与空调系统的需求额定功率差值为第五差值PB1,第五差值PB1可以为2%至10%倍的空调系统的需求额定功率。第四目标校准值与空调系统的需求额定功率差值为第六差值PA1,第六差值PA1可以为0%至5%倍的空调系统的需求额定功率。第五目标校准值与空调系统的需求额定功率差值可以为第七差值PA2,第七差值PA2可以为1%至7%倍的空调系统的需求额定功率。第六目标校准值与空调系统的需求额定功率差值为第八差值PB2,第八差值PB2为3%至15%倍的空调系统的需求额定功率。
参照图11所示,以降低压缩机的运行频率为例,Ptarget为能耗响应命令传输过来的目标值或是机组基于命令推断的目标值,即需求额定功率比例,Ptarget可以但不限为空调系统当前运行环境温度状态下的额定功率的下降百分比,如70% Prated(70%当前状态下的额定功率)。不同等级的能耗响应命令只需要修改对应的目标值,如从70%下降到50%即可,如从70%下降到50%即可。而其中PA1、PA2、PB1、PB2为控制回差。当控制目标参数是额定功率时,PA1可以为0%~5%Prated,PA2可以为1%~7%Prated,PB1可以为2%~10%Prated,PB2可以为3%~15%Prated。
在满足步骤1032,根据舒适度参数处于目标参数范围内,使空调系统执行降能耗控制操作的前提下,如图12所示,当空调系统的当前运行功率P≥Ptarget-PA1时,则认为压缩机需要降频满足降能耗目标,该处执行每过n秒,降低Z Hz(赫兹)的动作以减少对电网负荷的冲击,可选的,n为1~5s,Z可以为1~5Hz。
而当机组当前运行功率P(也即实时功率)处于中间区间时,则保持压缩机频率不动。当机组当前运行功率P处于底部区间(即下行段:P<Ptarget-PB2;上行段:P<Ptarget-PB1)时,说明实时功率距离降能耗的功率还有很大的距离,则允许压缩机进行正常的系统舒适性控制(升降频PI控制等)。而为了简化对系统控制的影响,机组的其他部件可以按照原有的PI控制逻辑进行控制以保证机组可靠性即可(如室外风机、室内风机、室外机电子膨胀阀等)
其中,上行段指的是当前运行功率随着运行时间逐渐升高的阶段,下行段指的是当前运行功率随着运行时间逐渐降低的阶段。
在一些实施例中,使空调系统的电辅热装置的功率降低,还可以包括:根据当前
室内温度超过第一预设温度,控制电辅热装置关闭;根据当前室内温度小于第二预设温度,控制电辅热装置开启,第一预设温度大于第二预设温度。
具体的,第一预设温度的取值范围可以为10℃至20℃,第一预设温度与第二预设温度的温度差a可以为1℃至3℃。
如图12所示,当机组包含室内电辅热装置的时候,还可以通过对电辅热装置进行开关进行控制。需要指出的是,压缩机的控制和电辅热装置的控制可以相对独立,也可以组合使用。本实施例更偏向于舒适性考虑的电辅热控制方法,如图12所示。其中T_set为电辅热强制关闭的预设温度(第一预设温度),a为控制回差。这两个值可以为空调系统的预设值,也可以是伴随降能耗命令自外部发送过来的值。可选的T_set为10~20℃,a为1~3℃。该控制的方法可以保证在室内环境温度T1较低时,利用电辅热加速制热;而当室内环境温度T1较高时,优先保证降能耗效果。
在一些实施例中,如图13所示,所述舒适度参数包括空调系统的室内机的第一温度参数,也就是说在,步骤120根据降低能耗请求,获取所述空调系统在当前运行状态下的舒适度参数,可以包括步骤1201:根据降低能耗请求,获取所述空调系统的室内机的第一温度参数。其中,第一温度参数为空调系统处于当前运行状态下的室内机的温度参数,可以包括以下任一种:空调系统的出风温度、室内换热器的温度、室内换热器周侧的环境温度。限定温度值是空调系统当前运行状态下所需求的目标温度值,即空调系统针对当前运行状态设定的温度值,其可以是用户向空调系统输入的温度值,也可以是空调系统根据当前运行状态对应设定的温度值。限定温度值与第一温度参数相对应,例如,第一温度参数为空调系统的出风温度,限定温度值为预先针对空调系统的出风设定的目标温度。
参照图13所示,在所述舒适度参数包括空调系统的室内机的第一温度参数的情况下,步骤130根据所述舒适度参数,控制所述空调系统运行,可以包括步骤201、步骤202和步骤203。具体的步骤201为:判断所述第一温度参数是否达到限定温度值。根据所述第一温度参数未达到所述限定温度值,执行步骤202,控制室内风机降低风档。根据所述第一温度参数达到所述限定温度值,执行步骤203,结束控制过程。
在一些实施例中,在获取所述空调系统的室内机的第一温度参数之前,还包括根据所述降低能耗请求,控制所述空调系统的压缩机降低运行频率;也就是说,步骤1201根据降低能耗请求,所述获取所述空调系统的室内机的第一温度参数,包括步骤211和步骤212。具体的,如图14所示,空调系统的控制方法包括如下步骤:
步骤110:接收降低能耗请求;
步骤211:根据降低能耗请求,控制压缩机降低运行频率;
步骤212:根据所述压缩机降低运行频率,获取所述空调系统的室内机的第一温度参数;
步骤201:判断第一温度参数是否达到限定温度值,若是则结束控制过程,若否则执行步骤202;
步骤202:控制室内风机降低风档。
本实施方式中,降低能耗请求是指降低空调系统当前运行功率的指令,降低能耗请求可以是空调系统中的处理器基于外部条件主动发出的指令,例如,智能化的空调系统基于电网的电价信息,当电价处于峰值时,为降低使用成本主动下调空调系统的运行的当前运行功率,减少耗电量。
或者,降低能耗请求也可以是外部设备向空调系统发出的指令,例如,空调系统接入智能电网系统中,智能电网系统具有内置数字计算机的高性能电力控制设备通过网络从发电设备到终端电力设备(如空调系统)彼此连接,当处于用电高峰期使电网的负荷较高时,电力控制设备为提高电网中电力供应和需求平衡,向高耗电设备如空调系统等发出降低能耗的指令,优化电力分配,预防停电,并降低成本。
或者,在智能楼宇系统的空调系统,空调系统接收智能楼宇系统的电力调配,当电价处于峰值或者智能楼宇中的电力供应负荷较大时,通过智能楼宇系统向空调系统发送降低能耗请求。
在步骤201至步骤202中,由于压缩机是空调制热的核心部件,压缩机的能耗占空调总能耗的大部分,因此,降低压缩机的运行频率可以迅速的降低空调系统的总的当前运行功率。
需要说明的是,当压缩机的运行频率降低时,空调系统的冷量或热量的输出能力随之下降,例如,在制冷模式下,室内换热器的蒸发温度高于限定温度值,使出风温度偏高,或者在制热模式下,室内换热器的冷凝温度低于限定温度值,使出风温度偏低,从而影响用户的舒适性。
其中,本实施方式中,在制冷模式下,室内机的第一温度参数具体指室内换热器的蒸发温度,在制热模式下,室内机的第一温度参数具体指室内换热器的冷凝温度。
可理解地,在其他实施方式中,室内机的第一温度参数还可以是室内换热器所处环境的温度,或者气流经过室内换热器之后的出风温度等。
在步骤201至步骤202中,当第一温度参数达到限定温度值时,说明当前室内换热器的蒸发温度或冷凝温度能够满足当前用户的制冷或制热需求,并且使空调系统的出风温度
能够满足用户的实际需求,因此,无需对空调系统的其他器件的运行状态进行调整,保持当前运行状态并结束控制过程;当第一温度参数未达到限定温度值时,则说明当空调系统在电网负荷较高或者电价处于高位等影响下,由于空调系统的功率受限,使压缩机的运行频率降低,在制冷模式下,室内换热器的蒸发温度高于限定温度值,使出风温度偏高,或者在制热模式下,室内换热器的冷凝温度低于限定温度值,使出风温度偏低,因此,通过降低室内风机的风档,使第一温度参数能够接近或达到限定温度值,使空调系统的出风温度更加接近用户的实际需求,提升用户的舒适性。
其中,第一温度参数未达到限定温度值具体的含义为:在制冷模式下,第一温度参数大于第一限定温度值;在制热模式下,第一温度参数小于第二限定温度值。
第一温度参数达到限定温度值具体的含义为:在制冷模式下,第一温度参数小于或等于第一限定温度值;在制热模式下,第一温度参数大于或等于第二限定温度值。
其中,第一限定温度值与第二限定温度值与用户设定的出风温度相关,第一限定温度值与第二限定温度值可以相等也可以不相等,在此不再具体限定。
其中,第一限定温度值与第二限定温度值与用户所设定的出风温度值以及空调系统的室内换热器所处的环境温度值相关,在一些实施方式中,第一限定温度值比用户所设定的出风温度值(即制冷温度)低3℃~5℃,第二限定温度值比用户所设定的出风温度值(即制冷温度)高3℃~5℃。
如图15所示,根据本公开的实施方式,空调系统的控制方法包括如下步骤:
步骤110:接收降低能耗请求;
步骤101:响应于降低能耗请求,获取空调系统的当前运行功率;
步骤102:判断空调系统的当前运行功率是否小于或等于所述降低能耗请求对应的目标功率,若是则直接执行步骤213,若否则先执行步骤211,再执行步骤213;其中,当前运行功率记为P,目标功率记为P1,步骤102也即是判断当前功率P与目标功率P1的大小关系。
步骤211:根据降低能耗请求,控制压缩机降低运行频率;
步骤213:获取空调系统的室内机的第一温度参数;
步骤201:判断第一温度参数是否达到限定温度值,若是则结束控制过程,若否则执行步骤202;
步骤202:控制室内风机降低风档。
在步骤110中,接收降低能耗请求也即是获取能耗降低指令,具体是指:云平台向空
调系统其发出的降低能耗请求,云平台可以是智能电网系统或智能楼宇系统等。
在步骤101至步骤102中,所述降低能耗请求对应的目标功率是指由智能电网系统或智能楼宇系统等向空调系统发出的降低能耗请求所限定的空调系统运行的功率值,当接收降低能耗请求后,首先判断空调系统当前运行的当前运行功率是否满足降低能耗请求所对应的所述降低能耗请求对应的目标功率,若当前运行功率小于或等于所述降低能耗请求对应的目标功率,则说明当前空调系统运行状态下的耗电量满足要求,使空调系统保持当前运行状态不变,若当前运行功率大于所述降低能耗请求对应的目标功率,则控制压缩机降低运行频率。
如图16所示,根据本公开的实施方式,空调系统的控制方法包括如下步骤:
步骤110:接收降低能耗请求;
步骤231:获取空调系统的运行模式;
步骤232:根据空调系统处于制热模式关闭电辅热装置;
步骤233:获取空调系统的当前运行功率;
步骤102:判断空调系统的当前运行功率是否小于或等于所述降低能耗请求对应的目标功率,若是则直接执行步骤213,若否则先执行步骤211,再执行步骤213;其中,当前运行功率记为P,目标功率记为P1,步骤102也即是判断当前功率P与目标功率P1的大小关系。
步骤211:根据降低能耗请求,控制压缩机降低运行频率;
步骤213:获取空调系统的室内机的第一温度参数;
步骤201:判断第一温度参数是否达到限定温度值,若是则结束控制过程,若否则执行步骤202;
步骤202:控制室内风机降低风档。
在步骤231和步骤232中,根据空调系统处于制热模式判断电辅热装置是否开启,若电辅热装置开启则关闭电辅热装置,若电辅热装置未开启则执行控制压缩机降低运行频率的步骤。可理解地,当压缩机处于制热模式时,若外部环境温度过低,仅开启压缩机无法满足制热需求时,还需要开启电辅热装置,以增加空调系统的热量输出,但是,电辅热装置是将电能转化为热能的方式来取暖,电辅热装置内部是电阻丝,通电后将电能转化成热能传到房间内,耗电量较大,因此在空调系统接收到降低能耗请求时,优先关闭电辅热装置。可理解地,当空调系统处于制冷模式时电辅热装置不会开启,因此,在制冷模式中的控制步骤不考虑电辅热装置的因素。
如图17所示,根据本公开的实施方式,空调系统的控制方法包括如下步骤:
步骤110:接收降低能耗请求;
步骤101:响应于降低能耗请求,获取空调系统的当前运行功率;
步骤102:判断空调系统的当前运行功率是否小于或等于所述降低能耗请求对应的目标功率,若是则直接执行步骤213,若否则先执行步骤211,再执行步骤213;其中,当前运行功率记为P,目标功率记为P1,步骤102也即是判断当前功率P与目标功率P1的大小关系。
步骤211:根据降低能耗请求,控制压缩机降低运行频率;
步骤213:获取空调系统的室内机的第一温度参数;
步骤201:判断第一温度参数是否达到限定温度值,若是则结束控制过程,若否则执行步骤241;;
步骤241:判断室内风机的风档是否处于最低档,若是则结束控制过程,若否则执行步骤242;
步骤242:控制室内风机降低1档,并返回执行步骤201。
在步骤241至步骤242中,在控制室内风机降低风档之前,判断室内风机当前的风档是否处于最低风档,若室内机风档未处于最低风档,则可以控制室内风机降低1档,使第一温度参数接近或达到限定温度值。
如图18所示,根据本公开的实施方式,空调系统的控制方法包括如下步骤:
步骤110:接收降低能耗请求;
步骤101:响应于降低能耗请求,获取空调系统的当前运行功率;
步骤102:判断空调系统的当前运行功率是否小于或等于所述降低能耗请求对应的目标功率,若是则执行步骤213,若否则执行步骤251、步骤252和步骤253,,再执行步骤213;
步骤251:获取压缩机的运行频率;
步骤252:判断运行频率f是否大于频率下限值f1,若是至执行步骤253,否则执行步骤213;
步骤253:控制压缩机在运行频率的基础上减小第一频率值;
步骤213:获取空调系统的室内机的第一温度参数;
步骤201:判断第一温度参数是否达到限定温度值,若是则结束控制过程,若否则执行步骤241;
步骤241:判断室内风机的风档是否处于最低档,若是则结束控制过程,若否则执行步骤242;
步骤242:控制室内风机降低1档,并返回执行步骤201。
在步骤251至步骤253中,本公开中的空调系统中的压缩机是指变频压缩机,变频压缩机相对转速恒定的压缩机而言,其转速能够在一定范围内连续调节,能连续改变输出能量,不同型号的压缩机在保证稳定运行的前提下具有不同的频率区间。例如,一些型号的压缩机的运行频率范围在20Hz至120Hz,该型号压缩机的频率下限值即为20Hz;另一些型号的压缩机的运行频率范围在25Hz至130Hz,该型号压缩机的频率下限值即为205Hz;还有一些型号的压缩机的运行频率范围在30Hz至130Hz,该型号压缩机的频率下限值即为30Hz;因此,基于不同型号的压缩机,其频率下限值具有不同值,在此不做具体限定。
当压缩机的运行频率大于频率下限值时,说明当前压缩机能够正常运行,并且压缩机的运行频率还具有可降低的空间,因此,控制压缩机的运行频率降低第一频率值,以继续降低空调系统整体运行的当前运行功率,降低空调系统的耗电量。当压缩机的运行频率小于或等于频率下限值时,则说明压缩机的运行频率不具备下调的空间,若继续降低压缩机的运行频率,会导致压缩机非正常运行,造成空调系统的运行不稳定,或造成压缩机的损坏,因此,停止继续下调运行频率,并执行步骤213,获取室内机的第一温度参数的步骤。
在一些实施方式中,若压缩机的运行频率小于频率下限值时,将压缩机的运行频率提高至频率下限值运行,以确保压缩机能够正常运行。
在一些实施方式中,第一频率值设置为固定值,第一频率值的取值范围可以是1Hz~20Hz,或者0.1Hz~10Hz,例如,第一频率值可以设置为1Hz、2Hz、3Hz、5Hz、6Hz、7Hz、8Hz、9Hz、10Hz、12Hz、14Hz、15Hz、18Hz、20Hz等。
在另一些实施方式中,第一频率值可以根据压缩机当前的运行频率值与频率下限值的差值进行调整,例如,第一频率值设置为与运行频率值减去频率下限值的差值呈正相关,差值越大则第一频率值越大,在多次调整压缩机的过程中,随着压缩机的运行频率与频率下限值的差值减小,则第一频率值也随之减小,多次调整压缩机的过程中,第一次降低压缩机的运行频率时的第一频率值最大,在第一次降低压缩机的运行频率后,第一频率值逐渐减小,以实现压缩机降频的精确调整,并且,每次调节过程中,第一频率值小于压缩机当前的运行频率值减去频率下限值的差值,避免压缩机的运行频率降低至频率下限值以下,提高压缩机运行的稳定性。
在另一些实施方式中,第一频率值可以根据空调系统当前的当前运行功率与降低能耗
请求所对应的指定功率的差值进行调整,第一频率值设置为与空调系统当前的当前运行功率减去降低能耗请求所对应的指定功率的差值呈正相关,差值越大则第一频率值越大,在多次调整压缩机的过程中,随着压缩机的运行频率与频率下限值的差值减小,则第一频率值也随之减小,以实现快速降低空调系统的当前运行功率,使空调系统能够快速地响应降低能耗请求。
需要强调的是,每次调节过程中,第一频率值小于压缩机当前的运行频率值减去频率下限值的差值,避免压缩机的运行频率降低至频率下限值以下,提高压缩机运行的稳定性。
如图19所示,根据本公开的实施方式,空调系统的控制方法包括如下步骤:
步骤110:接收降低能耗请求;
步骤211:根据降低能耗请求,控制压缩机降低运行频率;
步骤212:根据所述压缩机降低运行频率,获取所述空调系统的室内机的第一温度参数;
步骤201:判断第一温度参数是否达到限定温度值,若是则结束控制过程,若否则执行步骤202和步骤261;
步骤202:控制室内风机降低风档;
步骤261:控制室外风机降低风档。
在步骤202和步骤261中,当第一温度参数未达到限定温度值时,可同时控制室内风机和室外风机降低风档。
详细地,当室外风机以及室内风机的风档降低时,室内风机和室外风机的功率也随之降低,因此,降低室外机风档的主要作用在于降低空调系统的当前运行功率,在能够满足室外换热器中的冷媒与外部气流正常换热,使室外换热器中的冷媒能够吸收足够的热量或冷量的前提下,降低室外风机的风档,可以进一步的降低空调系统的当前运行功率,可理解地,当空调系统的当前运行功率不变时,通过降低室外风机的风档,可以提高压缩机的运行频率,从而提高空调系统的冷量或热量的输出能力,有利于使室内机的第一温度参数更接近或者达到限定温度值,进一步地优化空调系统的出风温度,提高用户的舒适性。
在一些实施方式中,室外风机的档位与运行频率呈正相关。详细地,当压缩机的运行频率较高时,则空调系统的冷量或热量输出较高,因此,室外换热器所需的换热量较大,因此,使室外风机处于高档位,以提高室外换热器的换热效率;当压缩机的运行频率较低时,则空调系统的冷量或热量输出较低,因此,室外换热器所需的换热量较小,因此,降低室外风机的档位使室外风机处于低档位,在满足室外换热器的换热量需求的前提下,降低空调系统的当前运行功率。
在一些实施方式中,室外风机具有n档,则将压缩机稳定运行状态下运行频率范围对应于由高到低等分为n个频率区域,每个频率区域对应室外风机的一个档位。例如,若压缩机稳定运行状态下的运行频率范围为20Hz至120Hz,室外风机由高到低分为5个档位,第五档室外风机的转速最高,第一档室外风机的转速最低,则将20Hz至120Hz由高到低等分为五个区域,第五区域为100Hz至120Hz,对应于室外风机的第五档;第四区域为80Hz至100Hz,对应于室外风机的第四档;第三区域为60Hz至80Hz,对应于室外风机的第三档;第二区域为40Hz至60Hz,对应于室外风机的第二档;第一区域为20Hz至40Hz,对应于室外风机的第一档。
在一些实施方式中,当第一温度参数未达到限定温度值减小出风口的开口面积,以进一步地降低空调系统的出风量,使第一温度参数更接近或达到限定温度值,提高用户使用的舒适性。具体地,本实施方式中,通过调节空调系统中的导风件的角度来改变出风口的开口面积,达到降低空调系统出风量的目的。
需要说明的是,在一些实施方式中,当空调系统的当前运行功率小于或等于所述降低能耗请求对应的目标功率,且室内风机的风档已经降至最低档,但是,室内机的第一温度参数仍未达到限定温度值时,则控制压缩机的运行频率升高,以提高空调系统的冷量或热量输出能力,保证用户使用的舒适性。
如图20所示,根据本公开的实施方式,在制热模式下,空调系统的控制方法包括如下步骤:
步骤110:接收降低能耗请求;
步骤271:关闭电辅热装置,并控制室内风机的风档降低至最低档;
步骤233:获取空调系统的当前运行功率;
步骤102:判断空调系统的当前运行功率是否小于或等于所述降低能耗请求对应的目标功率,若是结束,若否则执行步骤251、步骤252和步骤253;
步骤251:获取压缩机的运行频率;
步骤252:判断运行频率f是否大于频率下限值f1,若是至执行步骤253,否则结束。
步骤253:控制压缩机在运行频率的基础上减小第一频率值;并返回执行步骤102。
本实施方式中,当空调系统接收降低能耗请求后,若空调系统处于制热模式,则首先判断电辅热装置是否开启,若电辅热装置开启则关闭电辅热,并控制室内风机的风档降低至最低档,在降低室内风机的风档之后,再获取空调系统的当前运行功率,以及判断当前运行功率是否达到所述降低能耗请求对应的目标功率以及控制压缩机降低频率的步骤。
随着碳中和的普及以及空调节能运行的日益增长,在用电高峰,电网错峰供电越来越普遍。在电网错峰供电中,经常需要对空调系统的用电量进行调配。在电网错峰调配供电过程中,一个比较困难的点在于获得空调机组可响应的负荷(空调机组可响应的负荷即空调系统响应于电网错峰需求所能降低的用电量),其原因在于不同厂家的空调在不同的运行工况下的实际输出负荷均不同,而可响应的功率负载能力也随着工况变化而变化。在一些技术中,通过大数据算法去获取历史运行数据和用户习惯下的机组负荷情况,但是在可响应能力(可降低的用电量)上没有预估的结果或比较难以预估。
针对于上述可调电量难以预估的问题,在一些实施例中,本公开空调系统的控制方法,还包括可调电量的确定步骤,基于该可调电量的确定步骤,云平台(例如用电控制平台)可以获知空调系统可响应的负荷,即,云平台可以了解空调系统的能耗,从而可以更合理的调度用电。
所述可调电量的确定步骤,可以应用于空调系统,如图21所示,可调电量的确定步骤包括步骤301和步骤302。
