当空调***100运行制热模式时,通过换向组件2可以实现对冷媒流向的切换,换向组件2的第一接口21与第二接口22连通,第三接口23与第四接口24连通。制热模式下,冷媒依次经过压缩机1的排气口11、换向组件2的第一接口21、换向组件2的第二接口22、室内换热器4、节流装置5、室外换热器3、换向组件2的第四接口24、换向组件2的第三接口23,最后从压缩机1的吸气口12回到压缩机1,如此循环。此时室外换热器3为蒸发器,室内换热器4为冷凝器。冷媒流经室内换热器4时,和空气进行换热,向空气中释放热量,以此达到制热的目的。
冷媒支路6的进口61与排气口11相连,冷媒支路6的出口与吸气口12相连,冷媒支路6上设有第一换热装置71,第一换热装置71设在底盘8上。当冷媒支路6连通时,经压缩机1压缩后的高温冷媒可以经排气口11进入冷媒支路6,高温冷媒进入第一换热装置71后,可以对底盘8加热,避免底盘8上的水结冰,从而可以避免冰雪等堵塞底盘8的排水口,进而可以避免底盘8上的积水打烂室外风机的风叶。进入第一换热装置71内换热后的冷媒经压缩机1的吸气口12进入压缩机1内压缩。
例如,在本申请的一些实施例中,当空调***100运行制热模式时,可以控制冷媒支路6连通,此时经压缩机1压缩的一部分高温冷媒进入室内换热器4中换热,经室内换热器4换热后的冷媒经节流装置5后进入室外换热器3中换热,经室外换热器3换热后的冷媒,经压缩机1的吸气口12进入压缩机1内压缩。与此同时,经压缩机1压缩的另一部分高温冷媒可以经冷媒支路6进入第一换热装置71中,通过高温冷媒对底盘8加热,避免底盘8上的水结冰,从而可以避免冰雪等堵塞底盘8的排水口,进而避免底盘8上的积水打烂室外风机的风叶。在第一换热装置71内换热后的冷媒经压缩机1的吸气口12进入压缩机1内压缩。
当空调***100运行除霜模式时,可以控制冷媒支路6连通,此时经压缩机1压缩的一部分高温冷媒进入室外换热器3中换热,经室外换热器3换热后的冷媒经节流装置5后进入室内换热器4中换热,经室内换热器4换热后的冷媒,经压缩机1的吸气口12进入压缩机1内压缩。与此同时,经压缩机1压缩的另一部分高温冷媒可以经冷媒支路6进入第一换热装置71中,通过高温冷媒对底盘8加热,避免底盘8上的水结冰,从而 可以避免冰雪等堵塞底盘8的排水口,进而避免底盘8上的积水打烂室外风机的风叶。在第一换热装置71内换热后的冷媒经压缩机1的吸气口12进入压缩机1内压缩。
由此,通过设置冷媒支路6,并在冷媒支路6上设置第一换热装置71,可以通过压缩机1压缩后的一部分高温冷媒加热底盘8上的水,避免底盘8上的水结冰,从而可以避免冰雪等堵塞底盘8的排水口,进而避免底盘8上的积水打烂室外风机的风叶,减少了空调***100的耗电量,有效地节约了能源。
例如,在本申请的一些具体实施例中,当空调***100运行制热模式时,可以获取室外温度T,当室外温度T大于第一预设值T1且小于第二预设值T2时,可以开启冷媒支路6,使得经压缩机1压缩的另一部分高温冷媒可以经冷媒支路6进入第一换热装置71中,通过高温冷媒对底盘8加热,避免底盘8上的水结冰,从而可以避免冰雪等堵塞底盘8的排水口,进而避免底盘8上的积水打烂室外风机的风叶。由此,可以在保证空调***100制热效果的同时,节约了能源。
可选地,第一预设值T1可以为0~3℃,第二预设值T2可以为5~10℃。例如,第一预设值T1可以为3℃,第二预设值可以为7℃。在本申请的一些实施例中,在空调***100运行制热模式时,当3℃<T<7℃时,可以开启冷媒支路6,使得部分冷媒进入第一换热装置71对底盘8加热。
在本申请的一些具体实施例中,当空调***100运行除霜模式时,可以获取室外温度T,当室外温度T大于第一预设值T3且小于第二预设值T4时,可以开启冷媒支路6,使得经压缩机1压缩的另一部分高温冷媒可以经冷媒支路6进入第一换热装置71中,通过高温冷媒对底盘8加热,避免底盘8上的水结冰,从而可以避免冰雪等堵塞底盘8的排水口,进而避免底盘8上的积水打烂室外风机的风叶。由此,可以在保证空调***100制热效果的同时,节约了能源。
可选地,第三预设值T3可以为-3~0℃,第四预设值T4可以为0~5℃。例如,第三预设值T1可以为0℃,第二预设值可以为3℃。在本申请的一些实施例中,在空调***100运行制热模式时,当0℃<T<3℃时,可以开启冷媒支路6,使得部分冷媒进入第一换热装置71对底盘8加热,避免融化水结冰,直至除霜动作结束。
根据本申请实施例的空调***100,通过设置冷媒支路6,并在冷媒支路6上设置第一换热装置71,可以通过压缩机1压缩后的一部分高温冷媒加热底盘8上的水,避免底盘8上的水结冰,从而可以避免冰雪等堵塞底盘8的排水口,避免底盘8上的积水打烂室外风机的风叶。由此,可以在保证空调***100制热效果的同时,减少了空调***100的耗电量,节约了能源。
根据本申请的一些实施例,冷媒支路6的进口61包括第一进口611和第二进口612,第一进口611与第二接口22相连,第二进口612与第四接口24相连。当空调***100运行制热模式时,换向组件2的第一接口21与第四接口24连通,部分高温冷媒可以经第四接口24进入冷媒支路6。当空调***100运行除霜模式时,换向组件2的第一接口21与第二接口22连通,部分高温冷媒可以经第二接口22进入冷媒支路6。由此,在空调***100运行制热模式和除霜模式时,均可以使得部分高温冷媒进入冷媒支路6,通过高温冷媒对底盘8进行加热。
进一步地,第一进口611与第一换热装置71之间可以设有第一开关阀91。可选地,第一开关阀91可以为电磁阀。第一开关阀91打开时,第一进口611与第二接口22之间连通,当换向组件2的第一接口21与第二接口22连通时,冷媒可以进入冷媒支路6。第一开关阀91关闭时,第一进口611与第二接口22断开,此时冷媒不能进入冷媒支路6。例如,在除霜模式下,可以根据室外温度判断是否需要开启第一开关阀91。
第二进口612与第一换热装置71之间可以设有第二开关阀92。可选地,第二开关阀92可以为电磁阀。第二开关阀92打开时,当换向组件2的第一接口21与第四接口24连通时,冷媒可以进入冷媒支路6。第二开关阀92关闭时,第二进口612与第四接口24断开,此时冷媒不能进入冷媒支路6。例如,在制热模式下,可以根据室外温度判断是否需要开启第二开关阀92。
由此,通过设置第一开关阀91和第二开关阀92,可以根据实际运行情况控制冷媒支路6的通断,优化了空调***100的性能。
可以理解的是,在本申请的另一些实施例中,参照图2,冷媒支路6的进口61也可以连接在排气口11和换向组件2的第一接口21之间。这样,当冷媒支路6连通时,从排气口11排出的部分冷媒可以进入换向组件2,另一部分冷媒可以进入冷媒支路6。由此,在空调***100运行制热模式和除霜模式时,同样均可以使得部分高温冷媒进入冷媒支路6,通过高温冷媒对底盘8进行加热。
进一步地,冷媒支路6的进口61处可以设有第五开关阀95。可选地,第五开关阀95为电磁阀。
根据本申请的一些实施例,空调***100还包括第二换热装置72,第二换热装置72包括第一换热流路和第二换热流路,第一换热流路串联在第一换热装置71和吸气口12之间,第二换热流路串联在室内换热器4和室外换热器3之间。也就是说,从第一换热装置71中流出的冷媒可以进入第一换热流路,并流向吸气口12。从室内换热器4流出的冷媒可以进入第二换热流路并流向室外换热器3,或者从室外换热器3流出的冷媒可 以即进入第二换热流路并流向室内换热器4。
参照图1和图2,在制热模式下,当冷媒支路6打开时,从第一换热装置71中流出的冷媒可以流向第一换热流路,从室内换热器4流出的冷媒可以流向第二换热流路,第一换热流路内的冷媒和第二换热流路内的冷媒在第二换热装置72内换热后,第一换热流路中的冷媒可以流向压缩机1的吸气口12,第二换热流路中的冷媒可以经第一节流装置5节流后,进入室外换热器3内换热后流向压缩机1的吸气口12。这样,一方面,从第一换热装置71中流出的冷媒在第二换热装置72内换热后,可以吸收热量,提高温度,进而可以提升冷媒回气温度。另一方面,从室内换热器4流出的冷媒在第二换热装置72内换热后,温度降低,进而可以在室外换热器3中获取更多的热量,有利于提高制热效果。
根据本申请的一些实施例,冷媒支路6还包括分流支路62,分流支路62的第一端连接在第一换热装置71和第一换热流路之间,分流支路62的第二端连接在室外换热器3和室内换热器4之间。分流支路62打开时,从第一换热装置71流出的冷媒可以进入室内换热器4换热。
例如,当空调***100运行除霜模式时,在第一换热装置71内换热后的冷媒可以进入室内换热器4换热后流向吸气口12,由此有利于提高冷媒的回气温度。
在本申请的一些实施例中,分流支路62的第二端可以连接在室外换热器3和节流装置5之间。当空调***100运行除霜模式时,在第一换热装置71内换热后的冷媒,先经节流装置5节流后,进入室内换热器4换热后流向吸气口12,由此有利于提高冷媒的回气温度。
根据本申请的一些实施例,分流支路62上设有第三开关阀93,第三开关阀93可以打开或者关闭分流支路62。可选地,第三开关阀93为电磁阀。分流支路62的第一端与第一换热流路之间设有第四开关阀94。可选地,第四开关阀94为电磁阀。第四开关阀94打开时,从第一换热装置71流出的冷媒可以经第一换热流路流向吸气口12。第四开关阀94关闭时,从第一换热装置71流出的冷媒可以经分流支路62流向室内换热器4,进而流向吸气口12。
例如,空调***100制热运行时,可以打开第四开关阀94,并关闭第三开关阀93。当空调***100运行除霜模式时,可以打开第三开关阀93并关闭第四开关阀94。由此,可以根据空调***100的实际运行情况控制冷媒支路6中冷媒的流向,有利于优化空调***100的性能。
根据本申请的一些实施例,空调***100还包括电加热件81,如图3所示,电加热 件81设在底盘8上。电加热件81可以用于辅助加热底盘8,避免底盘8加热。
例如,当室外温度较低,通过冷媒支路6内的冷媒已经提供足够的热量来融化底盘8上的冰雪时,可以开启电加热件81,利用电加热件81加热底盘8,避免底盘8上的水结冰,从而可以避免冰雪等堵塞底盘8的排水口。由此,可以根据实际需要,选择不同的加热方式,在保证空调***100制热效果的同时,节约了能源。
根据本申请的一些实施例,第一换热装置71包括相对设置的第一换热部711、第二换热部712和连接部713,第一换热部711和第二换热部712分别连接在连接部713的两端且彼此相对设置。可选地,电加热件81设置在第一换热部711和第二换热部712之间。由此,可以使得第一换热装置71和电加热件81的排布更加紧凑,有利于减小第一换热装置71和电加热件81的整体占用空间,使得底盘8上各部件的排布更加合理。
可选地,第一换热装置71可以为U形换热管。U形管换热器的换热面积大,且结构简单、紧凑、密封性能高,不仅安装方便,后期检修、清洗也方便。
图4示出了根据本申请实施例的空调***100的控制方法的控制流程图。
如图4所示,根据本申请第二方面实施例的空调***100的控制方法,包括:
判断空调***100是否开启制热运行或是否进入除霜模式;
若空调***100开启制热运行或进入除霜模式,获取当前室外温度T;
在空调***100制热运行时,若室外温度T大于第一预设值T1且小于第二预设值T2,控制冷媒支路6连通;
在空调***100进入除霜模式时,若室外温度T大于第三预设值T3且小于第四预设值T4,控制冷媒支路6连通。
在制热模式下,当室外温度T满足T1<T<T2时,可以控制冷媒支路6打开,此时经压缩机1压缩的一部分高温冷媒进入室内换热器4中换热,经室内换热器4换热后的冷媒经第一节流装置5后进入室外换热器3中换热,经室外换热器3换热后的冷媒,经压缩机1的吸气口12进入压缩机1内压缩。与此同时,经压缩机1压缩的另一部分高温冷媒可以经冷媒支路6进入第一换热装置71中,通过高温冷媒对底盘8加热,避免底盘8上的水结冰,从而可以避免冰雪等堵塞底盘8的排水口,在第一换热装置71内换热后的冷媒经压缩机1的吸气口12进入压缩机1内压缩。
由此,可以通过压缩机1压缩后的一部分高温冷媒加热底盘8上的水,避免底盘8上的水结冰,从而可以避免冰雪等堵塞底盘8的排水口。
例如,在本申请的一些实例中,第一预设值T1可以为0~3℃,第二预设值T2可以 为5~10℃。例如,第一预设值T1可以为3℃,第二预设值可以为7℃。在本申请的一些实施例中,在空调***100运行制热模式时,当3℃<T<7℃时,可以开启冷媒支路6,使得部分冷媒进入第一换热装置71对底盘8加热。
第三预设值T3可以为-3~0℃,第四预设值T4可以为0~5℃。例如,第三预设值T1可以为0℃,第二预设值可以为3℃。在本申请的一些实施例中,在空调***100运行制热模式时,当0℃<T<3℃时,可以开启冷媒支路6,使得部分冷媒进入第一换热装置71对底盘8加热,避免融化水结冰,直至除霜动作结束。
根据本申请第二方面实施例的空调***100的控制方法,通过设置冷媒支路6,并在冷媒支路6上设置第一换热装置71,可以通过压缩机1压缩后的一部分高温冷媒加热底盘8上的水,避免底盘8上的水结冰,从而可以避免冰雪等堵塞底盘8的排水口,避免底盘8上的积水打烂室外风机的风叶。由此,可以在保证空调***100制热效果的同时,减少了空调***100的耗电量,节约了能源。
根据本申请的一些实施例,在空调***100运行制热模式时,当室外温度T大于等于第二预设值T2时,室外温度T较高,空调器***基本不会结冰且制热能力能够充分保证,此时可以关闭冷媒支路6。可以理解的是,当底盘8上设有电加热件81时,在空调***100运行制热模式时,当室外温度T大于等于第二预设值T2时,电加热件81也关闭。由此,可以保证空调***100制热能力的同时,减少耗电量。
进一步地,当底盘8上设有电加热件81时,在空调***100运行除霜模式时,当室外温度T小于等于第一预设值T1时,可以打开电加热件81,通过电加热件81对底盘8进行加热,避免底盘8上的水结冰,从而可以避免冰雪等堵塞底盘8的排水口。
例如,在除霜模式下,当室外温度小于等于0℃时,可以打开电加热件81,通过电加热件81对底盘8进行加热,避免底盘8上的水结冰,从而可以避免冰雪等堵塞底盘8的排水口。
在本申请的一些进一步实施例中,开启电加热件81后,可以根据室外温度T调整电加热件81的输出功率,在节能的同时实现底盘8不结冰。
例如,在本申请的一些实施例中,当T≤﹣15℃,可以关闭冷媒支路6,并控制电加热件81以最大功率W1运行,直至除霜动作结束。确保底盘8化霜的水滴可以及时排除底盘8,避免其结冰打烂风叶。
当-15℃<T≤-8℃,可以关闭冷媒支路6,并控制电加热件81以功率W2运行,直至除霜动作结束。其中W1>W2。在保证底盘8化霜的水滴及时排除的同时降低电加热件81的功耗,节约电能。
当-8℃<T≤-2℃,可以关闭冷媒支路6,并控制电加热件81以功率W3运行,直至除霜动作结束。其中W1>W2>W3。在保证底盘8化霜的水滴排除效率的同时降低电加热件81功耗,进一步节约电能。
当-2℃<T≤0℃,可以关闭冷媒支路6,并控制电加热件81以功率W3运行,直至除霜动作结束。其中W1>W2>W3>W4。在保证底盘8化霜的水滴排除效率的同时降低电加热管功耗,进一步节约电能。
