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本发明实施例的空调器及其控制方法和装置。
图1为根据本发明实施例的空调器的控制方法的流程图。
如图1所示,本发明实施例的空调器的控制方法,包括以下步骤:
S1,在空调器开机时,获取初始室内环境温度和初始室内环境湿度。
其中,初始室内环境温度和初始室内环境湿度是指空调器在开机时,尚未对室内温度和湿度造成影响时的室内温度和湿度。初始室内环境温度和初始室内环境湿度可在空调器开机时分别通过空调器的室内环境温度传感器和室内湿度传感器检测得到。
S2,根据初始室内环境温度和初始室内环境湿度获取初始露点温度。
在本发明的一个实施例中,可预先获取温度、湿度与露点温度的对应关系,并以表格的形式记录和存储该对应关系。由此,在获取初始室内环境温度和初始室内环境湿度后,可查表得到初始露点温度。
在本发明的一个具体实施例中,温度、湿度与露点温度的对应关系可如表1所示:
表1
Figure PCTCN2017117829-appb-000001
其中,T1、T2、T3、…Tn表示温度,Φ1、Φ2、Φ3、…、Φm表示湿度,TL11、TL12、TL13、…、TLmn表示露点温度,其中,m和n的大小决定上述对应关系中数据量的大小。
S3,控制空调器的室内换热器盘管温度等于初始露点温度,并保持空调器中压缩机的当前运行频率不变。
在本发明的一个实施例中,可在空调器运行时通过调整压缩机的运行频率以控制室内换热器盘管温度的升高或降低,以使室内换热器盘管温度达到初始露点温度。在室内换热器盘管温度达到初始露点温度时,可保持压缩机的当前运行频率不变。
由此,可在空调器降温过程中防止因室内换热器盘管温度过低而进行除湿,防止室内干燥。
S4,获取当前室内环境温度,并判断当前室内环境温度是否小于等于设定温度。
设定温度为用户设定的空调器的目标温度。如果用户在开机后未对温度进行设定,则以此前关机时空调器的目标温度作为设定温度。
在保持空调器中压缩机的当前运行频率不变后,可通过室内环境温度传感器获取当前室内环境温度,并将其与设定温度进行比较。
当当前室内环境温度大于设定温度时,可进一步判断室内环境温度是否在第一预设时间内维持不变,并在室内环境温度在第一预设时间内维持不变时,控制室内换热器盘管温度降低。也就是说,当室内环境温度未达到设定温度时,可适当控制室内换热器盘管温度降低以进行降温控制。
S5,如果当前室内环境温度小于等于设定温度,则获取当前室内环境湿度,并进一步根据当前室内环境温度和当前室内环境湿度获取当前含湿量和当前露点温度。
当当前室内环境温度小于等于设定温度时,空调器的温度调节已完成,进而可根据室内湿度状况进行加湿或除湿。
进一步地,可通过室内环境湿度传感器获取当前室内环境湿度,并查表1得到当前露点温度。
在本发明的一个实施例中,还可预先获取温度、湿度与含湿量的对应关系,并以表格的形式记录和存储该对应关系。由此,在获取当前室内环境温度和当前室内环境湿度后,可查表得到当前含湿量。
在本发明的一个具体实施例中,温度、湿度与含湿量的对应关系可如表2所示:
表2
Figure PCTCN2017117829-appb-000002
其中,T1、T2、T3、…Tn表示温度,Φ1、Φ2、Φ3、…、Φm表示湿度,dL11、dL12、dL13、…、dLmn表示含湿量,其中,m和n的大小决定上述对应关系中数据量的大小。
S6,根据室内换热器盘管温度、当前含湿量和当前露点温度控制空调器进行加湿工作或除湿工作。
具体地,可对当前含湿量进行判断,并对室内换热器盘管温度与当前露点温度之间的大小关系进行判断。如果当前含湿量大于第一预设值且室内换热器盘管温度大于当前露点 温度,则控制空调器的室内风机转速降低以进行除湿工作;如果当前含湿量小于第二预设值且室内换热器盘管温度小于当前露点温度,则控制空调器的室内风机转速增加以进行加湿工作,其中,第二预设值小于第一预设值。
在本发明的一个实施例中,第一预设值为温度为26℃、湿度为60%时所对应的含湿量,其数值为12.79;第二预设值为温度为26℃、湿度为40%时所对应的含湿量,其数值为8.47。
在本发明的一个具体实施例中,如图2所示,空调器的控制方法可包括以下步骤:
S001,空调器开机。
S002,获取设定温度Ts。
S003,检测初始室内环境温度T1(始)和初始室内环境湿度Φ(始)。
S004,根据T1(始)和Φ(始)获取初始露点温度TL(始)。
S005,维持室内换热器盘管温度T2等于TL(始)。
S006,维持压缩机的当前运行频率不变。
S007,获取当前室内环境温度T1,并比较T1与Ts。比较结果分别为S008和S016。
S008,T1≤Ts。
S009,检测当前室内环境温度T1和当前室内环境湿度Φ。
S010,根据T1和Φ获取当前含湿量dL和当前露点温度TL。除了根据上述实施例中的表1和表2查表获取当前含湿量dL、初始露点温度TL(始)和当前露点温度TL外,还可通过大量实验拟合出温度、湿度与含湿量之间以及温度、湿度与露点温度之间的关系式,然后根据T1(始)和Φ(始)以及上述关系式计算得到初始露点温度TL(始),并根据T1和Φ以及上述关系式计算得到当前含湿量dL和当前露点温度TL。
S011,对dL的大小进行判断,并比较T2与TL。判断和比较结果分别为S012和S014。
S012,dL<8.47且T2<TL。
S013,控制室内风机转速增加10%。
S014,dL>12.79且T2>TL。
S015,控制室内风机转速降低10%。
S016,T1>Ts。
S017,判断T1是否在10min内维持不变。如果是,则执行步骤S018;如果否,则返回步骤S005。
S018,控制室内换热器盘管温度降低1℃。
在步骤S013、S015和S018后可返回步骤S006。
根据本发明实施例的空调器的控制方法,在空调器开机时可根据初始环境状况获取初始露点温度,并将空调器的室内换热器盘管温度维持在该初始露点温度,以防止空调器在 降温控制过程中进行除湿,在室内换将温度达到空调器的设定温度后,可根据室内换热器盘管温度、当前含湿量和当前露点温度控制空调器进行加湿工作或除湿工作,由此,能够充分满足用户对湿度的舒适要求,并能够在不增加湿度传感器的基础上,利用空调器的基本部件实现对湿度的有效控制,因而还能够节约成本。
应当理解,空调器在制冷运行过程中,运行控制规则一般是优先进行室内温度控制。在室内湿度较低时,有可能还一直保持压缩机高频运行,这无疑会造成空气更加干燥;在室内湿度较高时,有可能还一直保持压缩机低频运行,无法进行有效除湿,造成空气低温潮湿,从而影响人体舒适性。为同时满足用户对温度和湿度的舒适要求,本发明还提出了一种在空调器制冷运行时对空调器进行温湿度控制的方法。
如图3所示,本发明实施例的空调器的控制方法,包括以下步骤:
S01,在空调器制冷运行时,获取设定温度、设定湿度。
在空调器开机运行时,用户可对空调器进行参数设定,通过遥控器等给定设定温度即空调器运行的目标温度和设定湿度即空调器运行的目标湿度等,以便空调器根据该设定的目标温度和目标湿度进行温度调节和湿度调节。如果用户在开机时未对温度和湿度进行设定,则以此前关机时空调器的设定温度、设定湿度作为此次运行时的设定温度和设定湿度。
S02,根据设定温度和设定湿度获取设定含湿量。
在本发明的一个实施例中,可预先获取温度、湿度与含湿量的对应关系,并以表格的形式记录和存储该对应关系。由此,在获取设定温度和设定湿度后,可查表得到设定含湿量。
在本发明的一个具体实施例中,温度、湿度与含湿量的对应关系可如表2所示。
S03,获取当前室内环境温度、当前室内环境湿度和当前室内换热器盘管温度。
本发明实施例的空调器可包括室内环境温度传感器、室内环境湿度传感器和对应室内换热器盘管设置的室内换热器盘管温度传感器,以便分别检测当前室内环境温度、当前室内环境湿度和当前室内换热器盘管温度。
S04,根据当前室内环境温度和当前室内环境湿度获取当前含湿量和当前露点温度。
同样地,可根据当前室内环境温度和当前室内环境湿度查表2得到当前含湿量。
在本发明的一个实施例中,还可预先获取温度、湿度与露点温度的对应关系,并以表格的形式记录和存储该对应关系。由此,在获取当前室内环境温度和当前室内环境湿度后,可查表得到当前露点温度。
在本发明的一个具体实施例中,温度、湿度与露点温度的对应关系可如表1所示。
S05,对设定温度与当前室内环境温度之间的大小关系、设定含湿量与当前含湿量之间的大小关系进行判断。
S06,根据判断结果、当前露点温度和当前室内换热器盘管温度对空调器进行温湿度控制。
具体地,如果设定温度小于等于当前室内环境温度且设定含湿量小于等于当前含湿量,则控制空调器降温、除湿运行;如果设定温度小于等于当前室内环境温度且设定含湿量大于当前含湿量,则控制空调器降温、保湿运行;如果设定温度大于当前室内环境温度且设定含湿量小于等于当前含湿量,则控制空调器保温、除湿运行;如果设定温度大于当前室内环境温度且设定含湿量大于当前含湿量,则控制空调器保温、保湿运行。
其中,在在对空调器进行温湿度控制之前,控制空调器的压缩机以根据当前室内环境温度和设定温度制定的规则运行。即以将当前室内环境温度调节至设定温度为目标控制压缩机运行,如果当前室内环境温度相对于设定温度较高,则提高压缩机的运行频率,如果当前室内环境温度接近或超过设定温度,则降低压缩机的运行频率。
本发明实施例的空调器可包括除湿阀,也可不包括除湿阀。
当空调器包括除湿阀时,通过控制除湿阀节流工作,并控制节流元件处于全开状态,以使空调器进行除湿。
具体而言,空调器可包括依次相连的压缩机、室外换热器、节流元件和室内换热器,以及对应设置在室内换热器上的室内风机,其中室内换热器的冷媒管路包括两部分,一部分冷媒管路的两端直接与节流元件和压缩机对应相连;另一部分冷媒管路的一端通过除湿阀与节流元件相连,另一端与压缩机相连。其中,除湿阀和节流元件可均为电子膨胀阀。
通过控制上述结构中的节流元件处于全开状态,并控制除湿阀进行节流工作,以控制除湿设备开启。此时,从压缩机出来的高温高压气态冷媒经室外换热器换热后,变为高温高压液态冷媒,然后一部分高温高压液态冷媒直接进入室内换热器的一部分冷媒管路进行热交换后,转变为低温低压液态冷媒流回至压缩机;另一部分高温高压液态冷媒经除湿阀节流后,变为低温低压液态冷媒,然后经室内换热器的另一部分冷媒管路进行热交换后流回至压缩机。其中,室内换热器的一部分冷媒管路作为冷凝器,实现对室内的制热,另一部分冷媒管路作为蒸发器,实现对室内的大量除湿,进而实现对室内的恒温除湿,保证室内湿度舒适性。
应当理解,除湿阀的开度减小时,除湿量增大;除湿阀的开度增大时,除湿量减小。当不需要控制除湿设备开启时,可控制除湿阀处于全开状态,并控制节流元件进行节流工作,即控制节流元件恢复正常工作状态。
当空调器不包括除湿阀时,通过控制室内风机的转速降低以进行除湿。
而对于温度控制,可通过调节压缩机的运行频率实现。
根据上述的除湿方式和温度控制方式,在本发明的一个实施例中,控制空调器降温、 除湿运行,包括:控制压缩机以上限频率运行,并在压缩机以上限频率运行时,判断当前室内换热器盘管温度是否大于当前露点温度;如果当前室内换热器盘管温度大于当前露点温度,则控制空调器的除湿阀的开度减小第一预设开度,或控制空调器的室内风机的转速降低至最低转速;如果当前室内换热器盘管温度小于等于当前露点温度,则控制空调器保持当前运行状态。

由此,在根据对设定温度与当前室内环境温度之间的大小关系、设定含湿量与当前含湿量之间的大小关系进行判断的判断结果进行温湿度控制时,还依据当前露点温度和所述当前室内换热器盘管温度实现温湿度控制,由此,能够同时满足用户对温度和湿度的舒适要求,并能够在不增加湿度传感器的基础上,利用空调器的基本部件实现对湿度的有效控制,因而还能够节约成本。
对应上述实施例,本发明还提出一种计算机可读存储介质。
本发明实施例的计算机可读存储介质,具有存储于其中的指令,当该指令被执行时, 空调器可执行本发明上述实施例提出的空调器的控制方法。
根据本发明实施例的计算机可读存储介质,能够使空调器充分满足用户对湿度的舒适要求。
对应上述实施例,本发明还提出一种空调器的控制装置。
如图6所示,本发明实施例的空调器的控制装置,包括第一获取模块10、第二获取模块20和控制模块30。
其中,第一获取模块10用于在空调器开机时,获取初始室内环境温度和初始室内环境湿度;第二获取模块20用于根据初始室内环境温度和初始室内环境湿度获取初始露点温度;控制模块30用于控制空调器的室内换热器盘管温度等于初始露点温度,并保持空调器中压缩机的当前运行频率不变。第一获取模块10还用于获取当前室内环境温度,控制模块30还用于判断当前室内环境温度是否小于等于设定温度,第一获取模块10还用于在当前室内环境温度小于等于设定温度时,获取当前室内环境湿度,第二获取模块20还用于根据当前室内环境温度和当前室内环境湿度获取当前含湿量和当前露点温度,控制模块30还用于根据室内换热器盘管温度、当前含湿量和当前露点温度控制空调器进行加湿工作或除湿工作。
其中,初始室内环境温度和初始室内环境湿度是指空调器在开机时,尚未对室内温度和湿度造成影响时的室内温度和湿度。初始室内环境温度和初始室内环境湿度可在空调器开机时由第一获取模块10分别通过空调器的室内环境温度传感器和室内湿度传感器检测得到。

在本发明的一个实施例中,控制模块30可在空调器运行时通过调整压缩机的运行频率以控制室内换热器盘管温度的升高或降低,以使室内换热器盘管温度达到初始露点温度。在室内换热器盘管温度达到初始露点温度时,可保持压缩机的当前运行频率不变。
由此,可在空调器降温过程中防止因室内换热器盘管温度过低而进行除湿,防止室内干燥。
设定温度为用户设定的空调器的目标温度。如果用户在开机后未对温度进行设定,则以此前关机时空调器的目标温度作为设定温度。
在保持空调器中压缩机的当前运行频率不变后,第一获取模块10可通过室内环境温度传感器获取当前室内环境温度,控制模块30可将当前室内环境温度与设定温度进行比较。
当当前室内环境温度大于设定温度时,控制模块30可进一步判断室内环境温度是否在第一预设时间内维持不变,并在室内环境温度在第一预设时间内维持不变时,控制室内换热器盘管温度降低。也就是说,当室内环境温度未达到设定温度时,可适当控制室内换热器盘管温度降低以进行降温控制。
当当前室内环境温度小于等于设定温度时,空调器的温度调节已完成,进而控制模块30可根据室内湿度状况进行加湿或除湿控制。
进一步地,第一获取模块10可通过室内环境湿度传感器获取当前室内环境湿度,第二获取模块20可查表1得到当前露点温度。
在本发明的一个实施例中,第二获取模块20还可预先获取温度、湿度与含湿量的对应关系,并以表格的形式记录和存储该对应关系。由此,在获取当前室内环境温度和当前室内环境湿度后,第二获取模块20可查表得到当前含湿量。
在本发明的一个具体实施例中,温度、湿度与含湿量的对应关系可如表2所示。
控制模块30可对当前含湿量进行判断,并对室内换热器盘管温度与当前露点温度之间的大小关系进行判断。如果当前含湿量大于第一预设值且室内换热器盘管温度大于当前露点温度,则控制模块30控制空调器的室内风机转速降低以进行除湿工作;如果当前含湿量小于第二预设值且室内换热器盘管温度小于当前露点温度,则控制模块30控制空调器的室内风机转速增加以进行加湿工作,其中,第二预设值小于第一预设值。
在本发明的一个实施例中,第一预设值为温度为26℃、湿度为60%时所对应的含湿量,其数值为12.79;第二预设值为温度为26℃、湿度为40%时所对应的含湿量,其数值为8.47。
根据本发明实施例的空调器的控制装置,在空调器开机时第二获取模块可根据初始环境状况获取初始露点温度,控制模块可将空调器的室内换热器盘管温度维持在该初始露点温度,以防止空调器在降温控制过程中进行除湿,在室内换将温度达到空调器的设定温度后,控制模块可根据室内换热器盘管温度、当前含湿量和当前露点温度控制空调器进行加湿工作或除湿工作,由此,能够充分满足用户对湿度的舒适要求,并能够在不增加湿度传感器的基础上,利用空调器的基本部件实现对湿度的有效控制,因而还能够节约成本。
此外,根据本发明的一个实施例,如图7所示,空调器的控制装置还可包括第三获取模块40。
其中,第三获取模块40用于在空调器制冷运行时,获取设定温度、设定湿度,第二获取模块20还用于根据设定温度和设定湿度获取设定含湿量。第一获取模块10用于获取当前室内环境温度、当前室内环境湿度和当前室内换热器盘管温度,第二获取模块20根据当前室内环境温度和当前室内环境湿度获取当前含湿量和当前露点温度,控制模块30用于对设定温度与当前室内环境温度之间的大小关系、设定含湿量与当前含湿量之间的大小关系 进行判断,并根据判断结果、当前露点温度和当前室内换热器盘管温度对空调器进行温湿度控制。
在空调器开机运行时,用户可对空调器进行参数设定,通过遥控器等给定设定温度即空调器运行的目标温度和设定湿度即空调器运行的目标湿度等,以便空调器根据该设定的目标温度和目标湿度进行温度调节和湿度调节。如果用户在开机时未对温度和湿度进行设定,则以此前关机时空调器的设定温度、设定湿度作为此次运行时的设定温度和设定湿度。
在本发明的一个实施例中,第二获取模块20可预先获取温度、湿度与含湿量的对应关系,并以表格的形式记录和存储该对应关系。由此,在获取设定温度和设定湿度后,第二获取模块20可查表得到设定含湿量。
在本发明的一个具体实施例中,温度、湿度与含湿量的对应关系可如表2所示。
在本发明的一个实施例中,第一获取模块10可分别通过室内环境温度传感器、室内环境湿度传感器和对应室内换热器盘管设置的室内换热器盘管温度传感器获取当前室内环境温度、当前室内环境湿度和当前室内换热器盘管温度。
然后,第二获取模块20可根据当前室内环境温度和当前室内环境湿度查表2得到当前含湿量。
在本发明的一个实施例中,第二获取模块20还可预先获取温度、湿度与露点温度的对应关系,并以表格的形式记录和存储该对应关系。由此,在获取当前室内环境温度和当前室内环境湿度后,第二获取模块20可查表得到当前露点温度。
在本发明的一个具体实施例中,温度、湿度与露点温度的对应关系可如表1所示。
控制模块30在设定温度小于等于当前室内环境温度且设定含湿量小于等于当前含湿量时,控制空调器降温、除湿运行,并在设定温度小于等于当前室内环境温度且设定含湿量大于当前含湿量时,控制空调器降温、保湿运行,以及在设定温度大于当前室内环境温度且设定含湿量小于等于当前含湿量时,控制空调器保温、除湿运行并在设定温度大于当前室内环境温度且设定含湿量大于当前含湿量时,控制空调器保温、保湿运行。
其中,在在对空调器进行温湿度控制之前,控制模块30可控制空调器的压缩机以根据当前室内环境温度和设定温度制定的规则运行。即以将当前室内环境温度调节至设定温度为目标控制压缩机运行,如果当前室内环境温度相对于设定温度较高,则提高压缩机的运行频率,如果当前室内环境温度接近或超过设定温度,则降低压缩机的运行频率。
本发明实施例的空调器可包括除湿阀,也可不包括除湿阀。
当空调器包括除湿阀时,通过控制除湿阀节流工作,并控制节流元件处于全开状态,以使空调器进行除湿。
具体而言,空调器可包括依次相连的压缩机、室外换热器、节流元件和室内换热器, 以及对应设置在室内换热器上的室内风机,其中室内换热器的冷媒管路包括两部分,一部分冷媒管路的两端直接与节流元件和压缩机对应相连;另一部分冷媒管路的一端通过除湿阀与节流元件相连,另一端与压缩机相连。其中,除湿阀和节流元件可均为电子膨胀阀。
通过控制上述结构中的节流元件处于全开状态,并控制除湿阀进行节流工作,以控制除湿设备开启。此时,从压缩机出来的高温高压气态冷媒经室外换热器换热后,变为高温高压液态冷媒,然后一部分高温高压液态冷媒直接进入室内换热器的一部分冷媒管路进行热交换后,转变为低温低压液态冷媒流回至压缩机;另一部分高温高压液态冷媒经除湿阀节流后,变为低温低压液态冷媒,然后经室内换热器的另一部分冷媒管路进行热交换后流回至压缩机。其中,室内换热器的一部分冷媒管路作为冷凝器,实现对室内的制热,另一部分冷媒管路作为蒸发器,实现对室内的大量除湿,进而实现对室内的恒温除湿,保证室内湿度舒适性。
应当理解,除湿阀的开度减小时,除湿量增大;除湿阀的开度增大时,除湿量减小。当不需要控制除湿设备开启时,可控制除湿阀处于全开状态,并控制节流元件进行节流工作,即控制节流元件恢复正常工作状态。
当空调器不包括除湿阀时,通过控制室内风机的转速降低以进行除湿。
而对于温度控制,可通过调节压缩机的运行频率实现。
根据上述的除湿方式和温度控制方式,控制模块30可通过执行以下步骤以控制空调器降温、除湿运行:控制压缩机以上限频率运行,并在压缩机以上限频率运行时,判断当前室内换热器盘管温度是否大于当前露点温度;如果当前室内换热器盘管温度大于当前露点温度,则控制空调器的除湿阀的开度减小第一预设开度,或控制空调器的室内风机的转速降低至最低转速;如果当前室内换热器盘管温度小于等于当前露点温度,则控制空调器保持当前运行状态。
控制模块30可通过执行以下步骤以控制空调器降温、保湿运行:判断当前室内换热器盘管温度是否大于当前露点温度;如果当前室内换热器盘管温度大于当前露点温度,则控制空调器保持当前运行状态;如果当前室内换热器盘管温度小于等于当前露点温度,则控制空调器的除湿阀的开度增大第一预设开度,或控制空调器的室内风机转速增加第一预设百分比。
控制模块30可通过执行以下步骤以控制空调器保温、除湿运行:控制压缩机以下限频率运行,并控制室内风机的转速降低至最低转速;在压缩机以下限频率运行且室内风机的转速降低至最低转速时,判断当前室内换热器盘管温度是否大于当前露点温度;如果当前室内换热器盘管温度大于当前露点温度,则控制空调器的除湿阀的开度减小第一预设开度;如果当前室内换热器盘管温度小于等于当前露点温度,则控制空调器保持当前运行状态。
控制模块30可通过执行以下步骤以控制空调器保温、保湿运行:控制压缩机停机。
由此,控制模块在根据对设定温度与当前室内环境温度之间的大小关系、设定含湿量与当前含湿量之间的大小关系进行判断的判断结果进行温湿度控制时,还依据当前露点温度和所述当前室内换热器盘管温度实现温湿度控制,由此,能够同时满足用户对温度和湿度的舒适要求,并能够在不增加湿度传感器的基础上,利用空调器的基本部件实现对湿度的有效控制,因而还能够节约成本。
