图1是根据一示例性实施例示出的现有技术的电化学制冷窗式空调***结构示意图。如图1所示，1为电化学氢泵，通过两条氢气管道连接室内外两个金属氢化物换热器，其中第一金属氢化物换热器2为室内换热器，第二金属氢化物换热器3为室外换热器，该换热***为风冷换热，通过两个离心风扇即第一风机4和第二风机5，将室内外的风吸到风道，通过电磁三通换向阀9、10、11和12从室内外出风口吹出，通过电磁三通换向阀的换向来实现连续制冷或制热。
在制热模式下，当给电化学氢泵1施加负压时，此时第一金属氢化物换热器2即室内换热器吸氢放热作为冷凝器，第二金属氢化物换热器3即室外换热器脱氢吸热，作为蒸发器，第一三通阀10和第二三通阀11的AB方向导通，第三三通阀12和第四三通阀13的AC方向导通，室内空气被离心风扇即第一风机4吸入第一风道6从室内出风口吹出，室外空气被第二风机5吸入第四风道9从室外出风口吹出，此时实现负压下的室内制热；当给电化学氢泵1施加正压时，此时第二金属氢化物换热器3即室外换热器吸氢放热作为冷凝器，第一金属氢化物换热器2即室内换热器脱氢吸热作为蒸发器，第一三通阀10和第二三通阀11的AC方向导通，第三三通阀12和第四三通阀13的AB方向导通，此时室内空气通过室内换热器被制冷经第二风道7从室外出风口吹出，室外空气通过室外换热器被制热经第三风道8从室内出风口吹出，此时实现正压下的室内制热。通过正负压在一定时间间隔下的交替施加，该空调***便实现连续制热。
上述电化学制冷窗式空调室内外换热器的交替制热，并将制热的换热器通过三通阀的切换交替联通至室内，实现室内的连续制热。而在使用中，由于室外换热器处于低温环境中，当室内换热器制热而室外换热器制冷时，室外换热器作为蒸发器易出现水汽凝结成霜现象，此时，当电化学氢泵电压换向，室外换热器需要制热时，首先需进行除霜/化霜，除霜预热吸收热量将延迟为室内提供热量，降低空调的制热效果，影响空调运行效果。本发明基于上述技术问题提出，通过除霜控制***、控制方法对电化学制冷窗式空调进行除霜，提高空调的制热效率，改善空调的运行效果。下面结合附图2-7对具体的实施方式和相关效果进行说明。
图2是根据一示例性实施例示出的一种电化学制冷窗式空调除霜控制方法的流程示意图。如图2所示，本发明一种实施方式的电化学制冷窗式空调除霜控制方法，包括：在步骤S110中，检测所述电化学制冷窗式空调的室外换热器的温度；在步骤S120中，将所检测的所述室外换热器的温度和温度设定值比较，判断室外换热器的温度是否小于或等于温度设定值；以及，当所检测的所述室外换热器的温度小于或等于温度设定值时，在步骤S130中，控制所述室外换热器工作在制热模式，以对所述室外换热器进行除霜。
上述方案中，电化学制冷窗式空调当处于低温环境中，室内换热器处于制热工作模式下，室外换热器作为蒸发器，吸氢放热产生水汽凝结成霜，会影响空调的正常运行，此时，当检测的电化学制冷窗式空调的室外换热器的温度Tw小于或等于温度设定值T时，认为室外换热器需要化霜/除霜，此时，控制室外换热器工作在制热模式，例如可以通过控制施加在电化学制冷窗式空调的电化学氢泵的电压换向，使得室外换热器由脱氢吸热工作模式切换到吸氢放热工作模式，即由蒸发器切换为冷凝器，自身放热过程中的热量对换热器的凝霜融化，以进行除霜操作，避免结霜对室外换热器的正常工作带来的影响，保证空调正常运行，提高制热效果和运行效率。利用空调自身的制热特性对室外换热器进行制热除霜，无需增加硬件结构，无需使用其他除霜装置，节约能源和成本。
上述方案中，例如可以在除霜完成后，通过室外换热器或室内换热器进行制热，并将制热模式下的换热器联通到室内风道，以继续进行室内制热。
图3是根据另一示例性实施例示出的一种电化学制冷窗式空调除霜控制方法的流程示意图。如图3所示，本发明另一种实施方式的电化学制冷窗式空调除霜控制方法，其中，控制所述室外换热器工作在制热模式，以对所述室外换热器进行除霜包括：在步骤S132中，控制所述电化学制冷窗式空调的电压换向，以使得所述电化学制冷窗式空调的室外换热器工作在制热模式，并在步骤S134中，控制所述电化学制冷窗式空调的室内风道停止 工作。
上述方案中，电化学制冷窗式空调的室内换热器和室外换热器交替进行制冷或制热，当室外换热器切换为冷凝器模式吸氢放热进行除霜时，电化学氢泵的电压换向，例如施加电压由正变为负，室内换热器脱氢吸热切换为蒸发器，此时，室内为制热需求，为避免室内换热器切换为蒸发器带来的制冷效果影响室内温度，将室内换热器和室内风道的联通断开，以避免室内温度降低，造成室内制热制冷模式出现紊乱，保证空调正常运行。
参考图1，当室外换热器进行除霜程序时，室内换热器为蒸发器使用，室内换热器和室内风道的联通关闭，例如可以控制室内风机即第一风机4停止运行，从而使得室内换热器不会将室内空气制冷并通过第一风道6循环到室内，从而避免对室内空气的降温造成的制冷制热模式紊乱，保证空调正常运行。
图4是根据另一示例性实施例示出的一种电化学制冷窗式空调除霜控制方法的流程示意图。如图4所示，该方法还包括：在步骤S140中，从所述室外换热器工作在制热模式开始计时，以获取除霜时间；以及，在步骤S150中，判断除霜时间是否达到设定时间，当所述除霜时间达到设定时间时，在步骤S160中，控制所述室外换热器联通所述室内风道，并控制室内换热器联通室外风道。
上述方案中，设定除霜时间/实际化霜时间为t，设定时间/预设化霜时间为t0，可以设定当t>t0时，室外换热器上的凝霜全部化完。当室外换热器工作在制热模式进行除霜时，即开始计时，得到除霜时间t，当除霜时间t到达设定时间t0时，认为除霜完成，将室外换热器和室内风道联通，室外换热器工作在冷凝器模式，吸氢放热继续为室内提供热风；此时，例如可以将室内换热器和室外风道联通，空调***切换至正常的室内制热模式，继续运行。
上述方案中，在室外换热器制热除霜完成后，继续利用其进行制热操作，仅切换换热器和室内外风道的联通方式即可，减少对空调的电化学氢泵的电压换向操作，节省***的程序操作频次，提高***的运行效率。
上述方案中，例如可以参考图1所示的电化学制冷窗式空调***的制冷制热工作模式对三通阀的AB、AC方向的导通/断开切换实现室内换热器、室外换热器和室内风道、室外风道的联通和断开控制
当除霜完成后，控制室外换热器继续工作在制热模式，控制第一三通阀10和第二三通阀11的AC方向导通，控制第三三通阀12和第四三通阀13的AB方向导通，则室内换热器的出风口联通室外，室外换热器的出风口联通室内，室外换热器将室外空气制热经 循环到室内，进行室内的制热。
图5是根据另一示例性实施例示出的一种电化学制冷窗式空调除霜控制方法的流程示意图。如图5所示，与图4所示的示例性实施例对应，该方法还包括：在步骤S140中，从所述室外换热器工作在制热模式开始计时，以获取除霜时间；以及，在步骤S150中，判断除霜时间是否达到设定时间，当所述除霜时间达到设定时间时，在步骤S172中，控制所述电化学制冷窗式空调的电压换向，以使得所述室内换热器工作在制热模式，并在步骤S174中，控制所述室内换热器联通室内风道，控制所述室外换热器联通室外风道。
上述示例性说明与图4所示的示例性说明相对应，当判断除霜程序完成后，控制室外换热器由吸氢放热模式/制热模式切换至脱氢吸热模式/制冷模式，室内换热器则相反，及由制冷模式切换至制热模式，继而通过室内换热器对室内进行制热，相应地，室内换热器和室内风道联通，室外换热器和室外风道联通，以继续运行制热程序，使空调正常运行。
当除霜完成后，控制室内换热器工作在制热模式，控制第一三通阀10和第二三通阀11的AB方向导通，控制第三三通阀12和第四三通阀13的AC方向导通，则室内换热器的出风口联通室外，室外换热器的出风口联通室内，室内换热器将室内空气制热并在室内循环，进行室内的制热。
上述方案中，根据检测到的室外换热器的温度或检测的室外温度来确定除霜时间，例如根据实验或经验值设定室外换热器的温度/室外温度与除霜时间的关系曲线，由检测的室外换热器的温度/室外温度确定设定时间，当图5所示方法中的除霜时间达到设定时间后，停止除霜，进入正常制热模式。
上述方案中，作为示例，例如可以根据实际检测的室外换热器的温度与除霜的设定时间的对应关系，建立经验表格，以在获取室外换热器的温度或室外温度后，根据该对应表格确定除霜的设定时间。
作为另一示例，例如还可以建立除霜的设定时间和室外换热器的温度/室外温度的计算公式，t0＝a-KTw；其中t0为除霜的设定时间，Tw为室外换热器的温度或室外温度，Tw≤0℃，当室外换热器的温度或室外温度低于0℃时，需要启动除霜程序，得到有效的除霜的设定时间；K为比例系数，a为除霜初始设定时间，即当室外换热器的温度或室外温度为0℃时的除霜时间，当室外换热器温度或室外温度越低，除霜的设定时间成正比例K地增加。
上述各实施方式的除霜控制方法/***，根据经验值可以确定电压换向时间即换热器吸收或释放完氢气的时间应远大于化霜时间，这样不会导致在化霜过程中出现换热器换向 现象，从而导致室内制冷制热紊乱。
上述电化学制冷窗式空调除霜控制方法利用电化学制冷窗式空调自身的制热特性，对处于低温环境的室外换热器进行除霜操作，不增加额外硬件情况下保证空调正常运行，提高空调运行的可靠性和运行效率。
