Description

空调系统及其化霜控制方法和装置 技术领域
本发明涉及空调技术领域,特别涉及一种空调系统的化霜控制方法、一种空调系统的化霜控制装置以及一种具有该化霜控制装置的空调系统。
背景技术
在空调系统中,当空调在制热模式下出现结霜的情况,需要切换为制冷模式,此时室外换热器作为冷凝器融化霜层。相关技术中,化霜过程需要设定强制退出时间,以免长时间化霜,导致室内机无法制热。其中,退出时间一般是固定不变的,因此固定时间设定的长短就必须满足全部运行环境的需求。当退出时间设定过短时,如果遇到外来雨雪天气影响,则化霜无法达到预定效果,换热器无法完全融化表面霜层。当退出时间设定过长时,如果低温低湿的环境下霜层不厚,则较短时间就可以完成化霜,但系统参数难以达到退出条件,内机就会因化霜执行时间过长而无法制热,室内制热效果受到影响。

具体实施方式
下面详细描述本发明的实施例,所述实施例的示例在附图中示出,其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的,旨在用于解释本发明,而不能理解为对本发明的限制。
下面结合附图来描述根据本发明实施例提出的空调系统的化霜控制方法、空调系统的化霜控制装置以及具有该控制装置的空调系统。
图1是根据本发明实施例的空调系统的化霜控制方法的流程图。
如图1所示,本发明实施例的空调系统的化霜控制方法可包括以下步骤:
S1,当空调系统每次进行化霜时,获取上次化霜时确定的化霜退出时间,并根据上次化霜时确定的化霜退出时间控制空调系统进行本次化霜。
其中,在本发明的实施例中,当空调系统首次进行化霜时,获取初始化霜退出时间,并根据初始化霜退出时间控制空调系统进行本次化霜。
也就是说,如果空调系统第一次进入化霜,则按照初始化霜退出时间(可以为经过大量实验测试数据获得的时间)控制空调系统进行本次化霜。如果空调系统不是第一次进入化霜,则根据上一次确定的化霜时间控制空调系统进行本次化霜。
S2,在空调系统进行本次化霜的过程中,获取室外环境温度,并获取室外换热器的出口温度。
其中,室外环境温度Tout可通过室外环境温度传感器实时获取,室外换热器的出口温度Tg可通过设置在室外换热器出口处的温度传感器获取。
S3,分别对室外环境温度和室外换热器的出口温度进行判断。
S4,如果室外换热器的出口温度小于第一预设温度且持续预设时间、且室外环境温度小于第二预设温度,则获取强制化霜时间以作为空调系统下次化霜时的化霜退出时间,并进行存储,其中,强制化霜时间大于空调系统本次进行化霜的时间,具体可根据实际情况进行标定,预设时间、第一预设温度和第二预设温度可根据实际情况进行标定。
根据本发明的一个实施例,在空调系统进行本次化霜的过程中,如果室外换热器的出口温度大于等于第一预设温度且持续预设时间、或者室外环境温度大于等于第二预设温度,则将空调系统本次进行化霜的时间作为空调系统下次化霜时的化霜退出时间,并进行存储。
根据本发明的一个实施例,在空调系统进行首次化霜的过程中,如果室外换热器的出口温度大于等于第一预设温度且持续预设时间、或者室外环境温度大于等于第二预设温度,则将初始化霜退出时间作为空调系统下次化霜时的化霜退出时间,并进行存储。
具体地,以空调系统第一次进入化霜为例。在空调系统进入化霜后,获取初始化霜退 出时间t1,并根据初始化霜时间t1控制空调系统进行本次化霜,并在化霜的过程中,获取当前室外环境温度Tout和室外换热器的出口温度Tg,并对其进行判断。如果室外换热器出口温度Tg<第一预设温度T1且持续预设时间ta、且室外环境温度Tout<第二预设温度T2,则说明当环境及使用条件恶劣或霜层较厚,需要延长化霜时间才能进一步融化室外换热器表面的霜,以保证运行制热时换热器的换热能力,此时获取强制化霜时间作为空调系统下次化霜时的化霜退出时间,并进行存储,以便下次空调系统进入化霜时使用。
如果室外换热器出口温度Tg≥第一预设温度T1且持续预设时间ta、或者室外环境温度Tout≥第二预设温度T2,则说明当前环境及使用条件改善或霜层较薄,此时可将空调系统本次进行化霜的时间(在该实施例中,空调系统本次进行化霜的时间为初始化霜退出时间)作为下次化霜时的化霜退出时间,并进行存储,以便下次空调系统进入化霜时使用。
在本发明的一个实施例中,强制化霜时间不是一个固定的值,具体的值需要根据上次化霜时确定的化霜退出时间的判断结果来确定。
作为一个具体示例,如图2所示,仍以空调系统首次进入化霜为例。
当系统第一次进入化霜后,初始化霜退出时间为t1。在空调系统进行第一次化霜期间,对室外换热器的出口温度Tg和室外环境温度Tout进行判断。如果满足判断条件:Tg≥T1且持续ta时间、或者Tout≥T2,则下一次化霜时的化霜退出时间t=t1;否则,下一次化霜时的化霜退出时间t=t2(此时强制化霜时间为t2),其中,t1<t2。在确定下一次化霜时的化霜退出时间后,对其进行存储,等待下一次化霜时使用。
在空调系统进行第二次化霜期间,当上次化霜时确定的化霜退出时间因满足判断条件为t1时,如果Tg≥T1且持续ta时间、或者Tout≥T2,则下一次化霜时的化霜退出时间t=t1;否则,下一次化霜时的化霜退出时间t=t2(此时强制化霜时间为t2)。当上次化霜时确定的化霜退出时间因不满足判断条件为t2时,如果Tg≥T1且持续ta时间、或者Tout≥T2,则下一次化霜时的化霜退出时间t=t2;否则,下一次化霜时的化霜退出时间t=t3(此时强制化霜时间为t3),其中,t2≤t3。在确定下一次化霜时的化霜退出时间后,对其进行存储,等待下一次化霜时使用。
在空调系统进行第三次化霜期间,当上次化霜时确定的化霜退出时间因满足判断条件为t1时,如果Tg≥T1且持续ta时间、或者Tout≥T2,则下一次化霜时的化霜退出时间t=t1;否则,下一次化霜时的化霜退出时间t=t2(此时强制化霜时间为t2)。当上次化霜时确定的化霜退出时间因不满足判断条件为t2时,如果Tg≥T1且持续ta时间、或者Tout≥T2,则下一次化霜时的化霜退出时间t=t2;否则下一次化霜时的化霜退出时间t=t3(此时强制化霜时间为t3)。当上次化霜时确定的化霜退出时间因满足判断条件为t2,如果Tg≥T1且持续ta时间、或者Tout≥T2,则下一次化霜时的化霜退出时间t=t1;否则,下一次化霜时的 化霜退出时间t=t2(此时强制化霜时间为t2)。当上次化霜时确定的化霜退出时间因不满足判断条件为t3时,如果Tg≥T1且持续ta时间、或者Tout≥T2,则下一次化霜时的化霜退出时间t=t3;否则,下一次化霜时的化霜退出时间t=t4(此时强制化霜时间为t4),其中,t3≤t4。
在空调系统进行第四次化霜期间,当上次化霜时确定的化霜退出时间因满足判断条件为t1时,如果Tg≥T1且持续ta时间、或者Tout≥T2,则下一次化霜时的化霜退出时间t=t1;否则,下一次化霜时的化霜退出时间t=t2(此时强制化霜时间为t2)。当上次化霜时确定的化霜退出时间因不满足判断条件为t2时,如果Tg≥T1且持续ta时间、或者Tout≥T2,则下一次化霜时的化霜退出时间t=t2;否则,下一次化霜时的化霜退出时间t=t3(此时强制化霜时间为t3)。当上次化霜时确定的化霜退出时间因满足判断条件为t2时,如果Tg≥T1且持续ta时间、或者Tout≥T2,则下一次化霜时的化霜退出时间t=t1;否则,下一次化霜时的化霜退出时间t=t2(此时强制化霜时间为t2)。当上次化霜时确定的化霜退出时间因不满足判断条件判定为t3时,如果Tg≥T1且持续ta时间、或者Tout≥T2,则下一次化霜时的化霜退出时间t=t3;否则,下一次化霜时的化霜退出时间t=t4(此时强制化霜时间为t4)。当上次化霜时确定的化霜退出时间因满足判断条件为t3时,如果Tg≥T1且持续ta时间、或者Tout≥T2,则下一次化霜时的化霜退出时间t=t2;否则,下一次化霜时的化霜退出时间t=t3(此时强制化霜时间为t3)。当上次化霜时确定的化霜退出时间因不满足判断条件为t4时,如果Tg≥T1且持续ta时间、或者Tout≥T2,则下一次化霜时的化霜退出时间t=t3;否则,下一次化霜时的化霜退出时间t=t4(此时强制化霜时间为t4)。其中,t3和t4可根据实际情况进行标定。
由上述实施例可知,在空调系统进行化霜时,都会根据上一次判断的结果来确定下次进行化霜时的化霜退出时间,以使化霜退出时间波动较小,在保证化霜效果的同时,尽快恢复空调系统的正常制热,提高用户舒适度。
需要说明的是,在上述实施例中,列举了四个化霜退出时间可选的情况,化霜退出时间可根据实际需要进行增加或减少,具体这里不再详述。
因此,本发明实施例的空调系统的化霜控制方法,能够根据当次化霜时室外换热器的出口温度及其持续时间,和化霜期间所处的环境温度,调整下一次的化霜退出时间。这样可以针对低温雨雪天气下霜层较厚无法在一次化霜过程融化干净的情况下,增加下一次化霜的运行时间,延迟退出,保证化霜能在足够的时间里完成。而在部分低温低湿度环境霜层不厚时,系统参数虽无法达到设定退出值,但霜层无需延长化霜时间也能被融化,此时化霜退出时间就可根据系统参数调整为原来的化霜退出时间(初始值),有助于在不影响后续制热的情况下,保证化霜效果,并且尽快恢复系统正常制热,减少室内机无法制热对房 间舒适度的影响。
综上所述,根据本发明实施例的空调系统的化霜控制方法,当空调系统每次进行化霜时,获取上次化霜时确定的化霜退出时间,并根据上次化霜时确定的化霜退出时间控制空调系统进行本次化霜,在空调系统进行本次化霜的过程中,获取室外环境温度,并获取室外换热器的出口温度,然后分别对室外环境温度和室外换热器的出口温度进行判断,如果室外换热器的出口温度小于第一预设温度且持续预设时间、且室外环境温度小于第二预设温度,则获取强制化霜时间以作为空调系统下次化霜时的化霜退出时间,并进行存储。由此,该方法能够根据室外环境和换热器的出口温度及其持续时间,来调整化霜的退出时间,在不影响换热效果的同时,保证化霜效果。
图3是根据本发明实施例的空调系统的化霜控制装置的方框示意图。如图3所示,本发明实施例的空调系统的化霜控制装置可包括:第一获取模块10、控制模块20、第二获取模块30和判断模块40。
其中,第一获取模块10,用于在空调系统每次进行化霜时,获取上次化霜时确定的化霜退出时间。控制模块20用于根据上次化霜时确定的化霜退出时间控制空调系统进行本次化霜。第二获取模块30用于在空调系统进行本次化霜的过程中,获取室外环境温度,并获取室外换热器的出口温度。判断模块40用于分别对室外环境温度和室外换热器的出口温度进行判断。控制模块20还用于,在室外换热器的出口温度小于第一预设温度且持续预设时间、且室外环境温度小于第二预设温度时,获取强制化霜时间以作为空调系统下次化霜时的化霜退出时间,并进行存储,其中,强制化霜时间大于空调系统本次进行化霜的时间。
根据本发明的一个实施例,在空调系统进行本次化霜的过程中,如果室外换热器的出口温度大于等于第一预设温度且持续预设时间、或者室外环境温度大于等于第二预设温度,控制模块20则将空调系统本次进行化霜的时间作为空调系统下次化霜时的化霜退出时间,并进行存储。
根据本发明的一个实施例,当空调系统首次进行化霜时,控制模块20通过第一获取模块10获取初始化霜退出时间,并根据初始化霜退出时间控制空调系统进行本次化霜。
根据本发明的一个实施例,在空调系统进行首次化霜的过程中,如果室外换热器的出口温度大于等于第一预设温度且持续预设时间、或者室外环境温度大于等于第二预设温度,控制模块20则将初始化霜退出时间作为空调系统下次化霜时的化霜退出时间,并进行存储。
需要说明的是,本发明实施例的空调系统的化霜控制装置中未披露的细节,请参照本发明实施例的空调系统的化霜控制方法中所披露的细节,具体这里不再赘述。
根据本发明实施例的空调系统的化霜控制装置,在空调系统每次进行化霜时,通过第 一获取模块获取上次化霜时确定的化霜退出时间,控制模块根据上次化霜时确定的化霜退出时间控制空调系统进行本次化霜。在空调系统进行本次化霜的过程中,通过第二获取模块获取室外环境温度,并获取室外换热器的出口温度,然后通过判断模块分别对室外环境温度和室外换热器的出口温度进行判断,在室外换热器的出口温度小于第一预设温度且持续预设时间、且室外环境温度小于第二预设温度时,控制模块获取强制化霜时间,以作为空调系统下次化霜时的化霜退出时间,并进行存储。由此,该装置能够根据室外环境和换热器的出口温度及其持续时间,来调整化霜的退出时间,在不影响换热效果的同时,保证化霜效果。
