具体实施方式
需要说明的是,在不冲突的情况下,本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本发明实施例。
为了使本技术领域的人员更好地理解本申请方案,下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本申请一部分的实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都应当属于本申请保护的范围。
本发明实施例公开一种光伏空调系统的控制方法,使得空调系统能够有效利用光伏系统产生的电能。光伏空调系统包括光伏系统和空调系统。
参见图1,图1为本发明实施例公开的一种光伏空调系统的控制方法的流程图。该控制方法包括:
步骤S11:确定光伏系统所处环境的光强值。
在光伏系统设置光强检测装置,利用光强检测装置进行光强检测,并输出光强值。在该实施例中,将光强检测装置设置于光伏系统中太阳能电池板的上侧,以使检测结果更加准确。
步骤S12:比较光伏系统所处环境的光强值和预设的光强区间。当该光强值高于该光强区间时,执行步骤S13。
步骤S13:在空调系统运行于制冷模式且当前的设定温度高于制冷模式最低温度的情况下,降低空调系统的设定温度,在空调系统运行于制热模式且当前的设定温度低于制热模式最高温度的情况下,提高空调系统的设定温度。
在确定光伏系统所处环境的光强值之后,比较该光强值和预设的光强区间,之后根据比较结果以及空调系统当前的运行模式控制空调系统的运行。
随着太阳光光照强度的变化,室内温度受太阳光照影响也会升高或降低,光伏系统输出的电能会随之变化。在光照强度较大时,室内温度会升高,光伏系统输出的电能也较多,此时通过调整空调系统的设定温度,以使得空调系统消耗更多电能,从而有效利用光伏系统产生的电能,并且能够同时满足用户对室内温度舒适性的要求。当空调系统处于制冷模式时,如果空调系统当前的设定温度高于制冷模式最低温度,则降低空调系统的设定温度,在降低空调系统的设定温度后,空调系统将消耗更多的电能,有效利用光伏系统产生的电能,同时也会增加空调系统的冷量输出,以抵消因太阳能光照强度增加引起的室内温度升高,使得用户不会因太阳光照增强而感到不适或需要手动调节设定温度,既减少用户的操作,又能实现空调系统根据室外温度自动调节冷量输出且不额外消耗公共电网电能的目的。同样,当空调系统处于制热模式时,如果空调系统当前的设定温度低于制热模式最高温度,则提高空调的设定温度,在提高空调系统的设定温度后,空调系统将消耗更多的电能,有效利用光伏系统产生的电能,在不增加公共电网电能消耗的同时能够进一步提高室内环境温度,使得用户感觉更加舒适。
这里需要说明的是,空调系统预存有制冷模式下的最低温度和最高温度,当空调系统在制冷模式下的设定温度处于该最高温度和最低温度之间时,能够使得室内温度呈现当前季节(如夏季)适宜人体活动的温度。同样,空调系统预存有制热模式下的 最低温度和最高温度,当空调系统在制热模式下的设定温度处于该最高温度和最低温度之间时,能够使得室内温度呈现当前季节(如冬季)适宜人体活动的温度。空调系统在制冷模式下的最低温度和最高温度,以及在制热模式下的最低温度和最高温度,可以是空调系统的原始设定,也可以由用户自行设定。
本实施例公开的光伏空调系统的控制方法,首先确定光伏系统所处环境的光强值,之后比较该光强值和预设的光强区间,在该光强值高于预设的光强区间的情况下,如果空调系统处于制冷模式且当前的设定温度高于制冷模式最低温度,则降低空调系统的设定温度,如果空调系统处于制热模式且当前的设定温度低于制热模式最高温度,则提高空调系统的设定温度。本实施例公开的光伏空调系统的控制方法,在光伏系统所处环境的光强值高于预设的光强区间的情况下,通过调整空调系统的设定温度,以使得空调系统消耗更多的电能,从而在保证或提升用户舒适度的情况下有效利用光伏系统产生的电能,无需额外消耗公共电网的电能,实现光伏系统与空调系统的良好结合。
参见图2,图2为本发明实施例公开的另一种光伏空调系统的控制方法的流程图。该控制方法包括:
步骤S21:确定光伏系统所处环境的光强值。
步骤S22:比较光伏系统所处环境的光强值和预设的光强区间。当该光强值高于该光强区间时,执行步骤S23,当该光强值低于该光强区间时,执行步骤S24。
步骤S23:在空调系统运行于制冷模式且当前的设定温度高于制冷模式最低温度的情况下,降低空调系统的设定温度,在空调系统运行于制热模式且当前的设定温度低于制热模式最高温度的情况下,提高空调系统的设定温度。
步骤S24:在空调系统运行于制冷模式且当前的设定温度低于制冷模式最高温度的情况下,提高空调系统的设定温度,在空调系统运行于制热模式且当前的设定温度高于制热模式最低温度的情况下,降低空调系统的设定温度。
在光照强度较小时,光伏系统输出的电能也较少,此时通过调整空调系统的设定温度,以使得空调系统消耗较少的电能。当空调系统处于制冷模式时,如果空调系统当前的设定温度低于制冷模式最高温度,则提高空调系统的设定温度,由于太阳光光照强度减小,室内温度会降低,用户对空调冷量输出的需求也将减小,此时适当提高设定温度不会影响用户的舒适性,在提高空调系统的设定温度后,空调系统消耗的电能减少,从而可以减少对公共电网的电能消耗,甚至避免消耗公共电网的电能。当空调系统处于制热模式时,如果空调系统当前的设定温度高于制热模式最低温度,则降低空调系统的设定温度,在降低空调系统的设定温度后,空调系统消耗的电能减少。 当光伏系统不能满足空调系统的用电需求时,由公共电网为空调系统进行辅助供电,通过执行步骤S24可以减少空调系统消耗的电能,因此在光照较弱导致光伏系统产生的电能较少的情况下,可以减少空调系统从公共电网获取的电能。
基于本发明实施例图2所示的光伏空调系统的控制方法,在光照较强光伏系统产生大量电能的情况下,能够有效利用光伏系统产生的电能,在光照较弱导致光伏系统产生的电能较少的情况下,可以在保证用户舒适度的情况下减少空调系统消耗的电能,从而减少空调系统从公共电网获取的电能,实现光伏系统与空调系统的良好结合。
在该实施例中,提高空调系统的设定温度可以采用以下方式:在空调系统处于制冷模式的情况下,直接将空调系统的设定温度调整至制冷模式最高温度;在空调系统处于制热模式的情况下,直接将空调系统的设定温度调整至制热模式最高温度。降低空调系统的设定温度,可以采用以下方式:在空调系统处于制冷模式的情况下,直接将空调系统的设定温度调整至制冷模式最低温度;在空调系统处于制热模式的情况下,直接将空调系统的设定温度调整至制热模式最低温度。
当然,提高空调系统的设定温度以及降低空提系统的设定温度还可以采用其他方式。例如:
在空调系统运行于制冷模式的情况下,降低空调系统的设定温度包括:获取空调系统当前的设定温度,计算空调系统当前的设定温度与温度调整步长的差值,判断该差值是否低于制冷模式最低温度,若是,则将空调系统的设定温度调整至制冷模式最低温度,否则,将空调系统的设定温度调整至该差值。
在空调系统运行于制冷模式的情况下,提高空调系统的设定温度包括:获取空调系统当前的设定温度,计算计算空调系统当前的设定温度与温度调整步长的和值,判断该和值是否高于制冷模式最高温度,若是,则将空调系统的设定温度调整至制冷模式最高温度,否则,将空调系统的设定温度调整至该和值。
在空调系统运行于制热模式的情况下,降低空调系统的设定温度包括:获取空调系统当前的设定温度,计算空调系统当前的设定温度与温度调整步长的差值,判断该差值是否低于制热模式最低温度,若是,则将空调系统的设定温度调整至制热模式最低温度,否则,将空调系统的设定温度调整至该差值。
在空调系统运行于制热模式的情况下,提高空调系统的设定温度包括:获取空调系统当前的设定温度,计算计算空调系统当前的设定温度与温度调整步长的和值,判断该和值是否高于制热模式最高温度,若是,则将空调系统的设定温度调整至制热模式最高温度,否则,将空调系统的设定温度调整至该和值。
需要说明的是,上述温度调整步长可以为一定值。作为本发明的优选实施方式, 温度调整步长与光伏系统所处环境的光强值相对应,例如:预存多个光强区间与温度调整步长的对应关系,在确定光伏系统所处环境的光强值后,确定该光强值所处的光强区间,之后依据预存的光强区间和温度调整步长的对应关系确定相应的温度调整步长,之后利用获取到的温度调整步长调整空调系统的设定温度。
在该实施例中,当光伏系统仅设置一个光强检测装置时,如果有杂物遮挡该光强检测装置,会导致光强检测装置输出的光强值出现偏差,后续依据该光强值控制空调系统运行的过程中就会出现偏差。
为了解决上述问题,可以在光伏系统设置多个光强检测装置,并且将多个光强检测装置设置于不同位置。相应的,后续基于多个光强检测装置输出的光强值确定光伏系统所处环境的光强值,由此降低因杂物遮挡光强检测装置导致出现控制偏差的概率。
在光伏系统设置有多个光强检测装置,并且多个光强检测装置位于不同位置的情况下,确定光伏系统所处环境的光强值可以采用多种方式。
例如:获取多个光强检测装置输出的光强值,之后计算获取到的多个光强值的平均值,确定计算得到的平均值为光伏系统所处环境的光强值。
例如:获取所述多个光强检测装置输出的光强值,之后计算获取到的多个光强值中除最小值之外的其他光强值的平均值,确定计算得到的平均值为光伏系统所处环境的光强值。
基于第二种实现方式,当某个光强检测装置被杂物遮挡后,该光强检测装置输出的光强值将会远低于其他光强检测装置输出的光强值,在确定光伏系统所处环境的光强值的过程中,剔除该不正常的数据,从而使得计算得到的光伏系统所处环境的光强值更加准确,相应的后续针对空调系统的控制也更加准确。
另外,在本发明实施例上述公开的各个控制方法中,当光伏系统所处环境的光强值位于预设的光强区间时,可以控制空调系统维持当前的设定温度继续运行。
本发明实施例还公开了光伏空调系统的控制方法,相应的,本发明实施例还公开光伏空调系统的控制装置,以实现上述控制方法。

比较单元200,用于比较光强值确定单元100确定出的光强值和预设的光强区间。
第一控制单元300,用于当光强值高于光强区间时,在空调系统运行于制冷模式且当前的设定温度高于制冷模式最低温度的情况下,降低空调系统的设定温度,在空调系统运行于制热模式且当前的设定温度低于制热模式最高温度的情况下,提高空调系统的设定温度。
本发明实施例公开的光伏空调系统的控制装置,光强值确定单元100确定光伏系统所处环境的光强值,之后比较单元200比较该光强值和预设的光强区间,在该光强值高于预设的光强区间的情况下,如果空调系统处于制冷模式且当前的设定温度高于制冷模式最低温度,则第一控制单元300降低空调系统的设定温度,如果空调系统处于制热模式且当前的设定温度低于制热模式最高温度,则第一控制单元300提高空调系统的设定温度。本发明实施例公开的光伏空调系统的控制装置,在光伏系统所处环境的光强值高于预设的光强区间的情况下,通过调整空调系统的设定温度,以使得空调系统消耗更多的电能,从而在保证或提升用户舒适度的情况下有效利用光伏系统产生的电能,无需额外消耗公共电网的电能,实现光伏系统与空调系统的良好结合。

基于本发明实施例图4所示的光伏空调系统的控制装置,在光照较强光伏系统产生大量电能的情况下,能够有效利用光伏系统产生的电能,在光照较弱导致光伏系统产生的电能较少的情况下,可以在保证用户舒适度的情况下减少空调系统消耗的电能,从而减少空调系统从公共电网获取的电能,实现光伏系统与空调系统的良好结合。
另外,第一控制单元300和第二控制单元400提高空调系统的设定温度的过程,以及降低空调系统的设定温度的过程可以参见前文的描述,这里不再进行赘述。
在该实施例中,在光伏系统设置有多个光强检测装置,并且多个光强检测装置位于不同位置的情况下,光强值确定单元100可以基于多个光强检测装置输出的光强值确定光伏系统所处环境的光强值。
例如:光强值确定单元100包括第一光强值确定模块。第一光强值确定模块获取多个光强检测装置输出的光强值,计算获取到的多个光强值的平均值,确定平均值为光伏系统所处环境的光强值。
或者,光强值确定单元100包括第二光强值确定模块。第二光强值确定模块获取多个光强检测装置输出的光强值,计算获取到的多个光强值中除最小值之外的其他光强值的平均值,确定平均值为光伏系统所处环境的光强值。
