本发明实施例提供的技术方案可以包括以下有益效果:
在上述实施例中,根据n台第一空调的型号和各所述第一空调在T时间段内的运行参数,估算所述第二空调在T时间段内设定温度为第一温度时的功耗;在本实施例中,估算空调功耗时,采用的数据不是根据实验室数据计算的,而是通过调取相同地区、相同运行时间段的n台第一空调的型号和运行参数,并根据这些参数估算所是第二空调在该时间段的功耗。在本实施例中,所述n台第一空调的运行参数是在同一运行时间段采集的,这些参数受每台所述第一空调的地理位置、室外环境、室内环境、户型、机型等因素的影响;此外,估算的第二空调的功耗也对应于该时间段,因此相对现有技术中通过实验数据计算的方式来说,本实施例换算出的空调功耗更准确。

在现有技术中,需要在空调进行节电控制后,对空调的节电量进行计算。节电量是根据空调在节电控制后,如空调从第一状态调整到第二状态的这段时间,即T时间段内,空调的预估功耗与空调的实际功耗的差值确定的。在上述过程中,空调的实际功耗可以根据空调反馈的功率和时间计算出,但空调的预估功耗是需要根据实验室的数据计算的。但因空调所在的地理位置、室外环境、室内环境、户型、机型等因素会对空调的功耗产生影响,因此实验室的数据无法反映空调实际的运行状态,计算出的预估功耗误差较大。本发明的整体构思是,获取T时间段内,处于第一状态的多台空调的型号和运行参数;根据上述参数,计算出空调在第一状态时,T时间段内的,预估功耗。
在本发明中,第一状态是指空调进行节电控制前所处的状态,第二状态是指空调进行节电控制后所处的状态,第一状态和第二状态可以是对空调设定温度的调节,如第一温度调至第二温度;也可也是空调风速的调节,如第一风速档位调至第二风速档位。
第一空调,是在计算第二空调的预估功耗时,从数据库调取其型号和运行参数的一类空调;第一空调在T时间段内的运行状态,与所述第二空调在进行节电控制前的运行状态相同,即第一空调位于第一状态。第一空调与第二空调位于同一地区,如同一市或同一区,室外环境基本相同。
第二空调,是本发明中进行节电控制,并需要计算其预估功耗的空调。第二空调在节电控制前与第一空调相同,处于第一状态;在对第二空调进行节电控制后,第二空调从第一状态调整至第二状态。
第一空调或第二空调的型号,是指可以反映空调匹数和能耗等级的一类参数,如机器型号、机器编码。
能耗等级,可以由能效标识进行表示,可以按照国家标准划分为五个等级,等级1表示产品节电已达到国际先进水平,能耗最低;等级2表示产品比较节电;等级3表示产品能源效率为我国市场的平均水平;等级4表示产品能源效率低于市场平均水平;等级5是产品市场准入指标,低于该等级要求的产品不允许生产和销售;也可以是按照本行业标准或企业标准,进行等级划分。
功率修正系数,是根据第一空调的型号和第二空调的型号确定的,用以对第一空调的功率进行修正,进而算出第一空调的修正功率。
预估功耗,是第二空调在进行节电控制前,即在第一状态时,对应于T时间段内的功耗。
实际功耗,是第二空调在进行节电控制后,即在第二状态时,对应于T时间段内的功耗。
图1示出了本发明实施例的流程示意图。如图1所示:
在一些示例性的实施例中,一种空调功耗估算方法,包括:
步骤S101,获取处于同一地区的n台第一空调的型号和各所述第一空调在T时间段内的运行参数;所述运行参数包括:在所述T时间段内各所述第一空调上报的s次功率P
ix,以及对应于各功率P
ix的运行时间t
ix;i=1,2,…,n,n为不小于1的正整数;x=1,2,...,s,s为不小于1的正整数;
步骤S102,根据所述n台第一空调的型号和第二空调的型号,确定所述n台第一空调的功率修正系数α
i;
步骤S103,根据所述n台第一空调中各所述第一空调在T时间段内的运行参数和所述功率修正系数α
i,计算所述第二空调在所述T时间段内的预估功耗W1。
在上述实施例中,根据n台第一空调的型号和各所述第一空调在T时间段内的运行参数,计算第二空调在T时间段内的预估功耗。在本实施例中,估算空调功耗时, 采用的数据不是根据实验室数据计算的,而是通过调取同一地区、同一运行时间段的n台第一空调的型号和运行参数,并根据这些参数计算第二空调的预估功耗W1。在本实施例中,所述n台第一空调的运行参数是在同一运行时间段采集的,这些参数受每台所述第一空调的地理位置、室外环境、室内环境、户型、机型等因素的影响;此外,第二空调的预估功耗W1也对应于该时间段,因此相对现有技术中通过实验数据计算的方式来说,本实施例换算出的空调功耗更准确。
在一些可选的实施例中,第二家电在节电控制前的设定温度为第一温度,在节电控制后,将设定温度设为第二温度。则上述实施例中调取的n台第一空调的设定温度为第一温度,计算出的预估功耗是第二家电在设定温度为第一温度时,运行T时间段内的功耗。在本实施例中,第二家电通过调整设定温度,进而达到节电的目的,因此在本实施例中,n台第一家电所处的第一状态,是指设定温度为第一温度;第二家电进行节电控制后所处的第二状态,是指设定温度为第二温度。
在一些可选的实施例中,步骤S101,可以从云服务器或其他设备获取n台第一空调的型号和运行参数。云服务器或其他设备,用于对同一地区的空调的运行状态,如第一状态和第二状态,进行监测,当空调的功率发生变化时,会主动上报云服务器或其他设备,告知其当前功率,因此云服务器或其他设备还记录各空调的功率,以及对应于该功率的运行时间。
在一些可选的实施例中,步骤S102,可以从本地或云服务器或其他设备,查询n台第一空调的功率修正系数α
i。
可选的,在数据库中,记录了不同型号的空调的功率修正系数α
i,根据第一空调的型号和第二空调的型号,可以直接查询到第一空调的功率修正系数α
i。
可选的,在数据库中,记录了空调在不同匹数和不同能耗等级所对应的系数;如表1。
| 匹数 | 一级能耗 | 二级能耗 | 三级能耗 |
| 1P | A11 | A12 | A13 |
| 1.5P | A21 | A22 | A23 |
| 2P | A31 | A32 | A33 |
| 3P | A41 | A42 | A43 |
表1
其中,空调的型号对应于空调的匹数和能耗等级,通过识别空调的型号,可以确定空调的匹数和能耗等级。
进一步的,所述步骤S102具体包括:
根据所述第二空调的型号,确定所述第二空调的系数a
0;
根据所述n台第一空调的型号,确定所述n台第一空调的系数a
i;
根据公式4,计算所述n台第一空调的功率修正系数α
i;
如,第二空调的型号对应的匹数为1P,能耗等级为一级能耗,则a
0为A11;共获取n台第一空调,分别编号为1到n,其中编号为3(即,i=3)的第一空调的型号对应的匹数为3P,能耗等级为二级能耗,则a
3=A42;根据以上信息和公式4,可以算出α
3=A42/A11。类似的,可以算出n台第一空调的系数α
i,即α
1,α
2,…,α
n。
在一些说明性的实施例中,步骤S103,包括:
计算所述n台第一空调中各第一空调的修正功率P
i;
进一步的,
根据公式1,计算所述n台第一空调中各第一空调的修正功率P
i:
进一步的,
进一步的,
根据公式3,计算在所述T时间段内所述第二空调的预估功耗W1;
上述实施例,给出了计算预估功耗W1的具体计算方法和相应的公式。在获取n台第一空调的型号和状态参数后,计算各第一空调的修正功率P
i,然后再将计算出的修正功率P
i取平均,算出n台第一空调的平均修正功率
即第二空调在未进行节电控制前,处于第一状态,在T时间端内的预估功耗;然后再将上述步骤中算出的
与T相乘,计算出在T时间段内所述第二空调的预估功耗W1。
在一些可选的实施例中,还包括计算第二空调在进行节电控制后的节电量。如,第二空调在进行节电控制后,设定温度从第一温度调至第二温度,则计算第二空调在 T时间段内的实际功耗W2,然后根据W1和W2计算T时间段内第二空调的节电量,即功耗节约值ΔW。
进一步的,根据公式5,计算所述第二空调在所述T时间段内的功耗节约值ΔW;
ΔW=W1-W2 (5)。
进一步的,计算实际功耗W2的步骤,具体包括:
获取第二空调在T时间段内的运行参数,包括:在所述T时间段内第二空调上报的m次功率P
y,以及对应于各功率P
y的运行时间t
y;
根据公式6,计算所述实际功耗W2:
其中,y=1,2,...,m,m为不小于1的正整数。
上述实施例,实际功耗W2是根据第二空调在T时间段的运行参数算出的,第二空调在运行时每当功率发生变化会上报其当前功率,从而获取其在T时间段内的至少一个运行功率,以及相应的运行时间。
可选的,第二空调在T时间段内的运行参数可以是在本端的数据库记录,或者从云服务器或其他设备上获取。
在一些说明性的实施例中,在步骤S101中,先获取与第二空调的型号相同的m台第一空调,其中m为小于等于n的正整数。若m小于n,则再随机获取n-m台第一空调。如n为100台,则先在数据库中获取与第二空调相同型号的设定温度为第一温度的第一空调,若当前数据库中符合该条件的第一空调仅为60台,则剩下的40台则随机在数据库中获取设定温度为第一温度的第一空调。进一步的,m台第一空调与第二空调的型号相同,则功率修正系数α
i=1。在上述实施例中,在数据库中优先获取与第二空调同型号的第一空调,以保证抽取的第一空调的运行环境最接近第二空调,进而提高预估功耗的准确度。
为了对上述实施例给出具体的说明,图2示出了本发明实施例的一种空调功耗估算方法的流程示意图。如图2所示,所述方法包括:
步骤S201,根据节电控制方案,将用户空调的设定温度从T11调节为T12;
步骤S202,根据上报的功率,计算T时间段内,如10:00-11:00,所述用户空调的实际功耗W2;
根据上报功率的情况,获取的数据如下:
P
1=700W,10min;P
2=1000W,20min;P
3=800W,15min;P
4=600W,15min;
计算W2=48KW·min=2880*10
3J。
步骤S203,采集同一地区的多台设定温度为T11的空调的运行数据,计算预估功耗W1;
考虑到某一地区相同型号的数量会有所不同,我们规定采集同一地区的100台空调进行估算T11温度下的功耗情况。优先考虑相同型号的空调,当相同型号的空调不够100台时,再随机抽取凑够100台。根据这100台设备功耗的加权平均来估算T11温度下的功耗W1。
其中,W1的具体计算方法如下:
步骤S204,根据预估功耗W1和用户空调的实际功耗W2,计算10:00-11:00的节电量。
修正系数参照表1,表1记录了过去一年相同匹数相同能耗等级的设备的平均单位能耗情况。
举例说明,某一地区的用户空调是1p,二级能耗的,由T11调节到T12温度下运行了1个小时,该地区,相同型号的空调在这一个小时内设定在T11温度下的有60台,则这60台的修正系数α
1-60=1,其余的40台由在1个小时内设定在T11温度下的其他型号的空调中抽取,假设我们抽的全是1p,1级能耗的,则这40台的修正系数为α
61-100=A12/A11。
则用户空调在T11设定温度下的预估功耗W1为:
上述实施例给出了本发明一种空调功耗估算方法的具体实施方式,在上述实施例中,根据100台第一空调的型号和各所述第一空调在10:00到11:00的运行参数,计算第二空调,即用户空调在10:00到11:00这1小时的预估功耗。相对现有技术中通过实验数据计算的方式来说,本实施例换算出的空调功耗更准确。
