需要说明的是，在本申请中，采用“并行耦合梯级吸气压缩制冷循环”的制冷机组，显著提高机组处理热湿负荷能力，提高机组能效。室内采用梯级换热的双蒸发器***，分级处理显热和潜热负荷，高温蒸发器处理显热负荷，低温蒸发器主要处理潜热负荷，实现温度、湿度的解耦控制；同时通过双蒸发温度，降低蒸发器传热过程的不可逆损失，提高多排换热器的换热效率；室外采用“双吸气并行压缩”的新型压缩机，通过并行压缩可以降低蒸发器入口的闪发干度，进一步提高换热效率及***能效；同时梯级吸气并行压缩循环可在宽工况范围内实现高效运行。
需要说明的是，在本申请中，采用光伏直驱技术通过多电源管理协调控制、能量互补及平滑切换技术，能够根据空调器运行所需功率以及光伏发电功率实时调整市电和太阳能的供电比例，实现太阳能高效利用。
需要说明的是，在本申请中，采用双吸气并行压缩转子压缩机，梯级换热蒸发器及耦合蒸发式冷凝器，构建并行耦合梯级吸气压缩制冷循环，实现了温度、湿度独立控制及宽工况下节能高效运行；以蒸气压缩制冷为核心，结合通风、蒸发冷却、太阳能利用技术，创建了复合制冷家用空调***；空调***采用低GWP环保制冷剂，可以是R32、R152a等。
本申请提供的空调***包括：空调室内机80和空调室外机90与通风装置70、光伏供电装置100、机械换气装置、室内控制器110和室外控制器60等部件。
空调室外机90包括：压缩机10、冷却装置50、第一冷凝器21和第二冷凝器22等。
冷却装置50包括：喷淋结构51或者喷雾结构、接水盘52、回流管路54、循环水泵53、供水管路55、储水箱等，或者，当城市用水水压足够或水供应较多时，也可以不用储水箱和循环水泵53。
冷却装置50可以采用喷淋结构51或者喷雾结构，并结合接水盘52、回流管路54、供水管路55及循环水泵53；当采用喷淋结构51时，水从第二冷凝器22的上方或前方，经布水器(如有)，直接流到第二冷凝器22的翅片和换热管上进行蒸发，未蒸发的水流到接水盘52进入储水箱，由循环水泵53再一次泵至换热器的上方或前方进行循环；如果使用喷雾装置，则水被喷入空气进行蒸发降温，降温后的空气再流经换热器进行换热。
制冷机组采用第一冷凝器21和第二冷凝器22，第二冷凝器22位于迎风侧，第一冷凝器21位于背风侧。当喷淋结构51时，第二冷凝器22优选翅片管换热器，以提高蒸发冷却效果，第一冷凝器21选择微通道换热器，以减少***充灌量；当使用喷雾装置时，可都选择微通道换热器，进一步减少***充灌量。
制冷机组采用第一蒸发器41和第二蒸发器42，其中高温蒸发器主要处理室内显热负荷、低温蒸发器主要处理室内潜热负荷，两组换热器并联设置。待处理空气先经过高温蒸发器进行降温，再经过低温蒸发器进行除湿(同时也降温)，达到送风条件后再送入室内。进而达到温度湿度独立控制的目的。
具体地，第一蒸发器41为高温蒸发器，确保第一蒸发器41能够处理室内的显热负荷，第二蒸发器42为低温蒸发器，确保第二蒸发器42能够处理室内的潜热负荷，从而实现对室内空气的梯级降温，进而提高了空调***处理热湿负荷能力，降低了蒸发装置40传热过程中不可逆的热量损失，有利于提升空调***的换热效率。
需要说明的是，在本申请中，制冷机组采用的压缩机10为“双吸气并行压缩”的新型转子压缩机，本申请提供的压缩机10具有三个独立的压缩缸，压缩机10包括第一吸气口11、第二吸气口12、第三吸气口13和排气口14，结合双温蒸发装置40和中间的闪发装置30进而形成并行耦合梯级吸气压缩制冷循环，第一吸气口11的气体来自中间补气，该压缩缸的设置能够降低两个蒸发器入口的闪发干度，提高蒸发器的换热效率及***能效，尤其在室内、外的温差较大或制冷机组负荷较大时提效显著；第二吸气口12和第三吸气口13的气体分别来自第一蒸发器41和第二蒸发器42，两个压缩缸的设置能够实现高温和低温蒸发换热，进而实现对空气的梯级降温，减少换热过程的不可逆损失，提升蒸发装置40的换热效率及***能效，尤其是在室内外温差较小或制冷机组负荷较小时提效显著；所以三个压缩缸形成的并行耦合梯级吸气压缩制冷循环能够实现在宽范围内耦合提升***能效。
具体地，从压缩机10的排气口14排出的高温高压制冷剂气体分别进入第一冷凝器21和第二冷凝器22进行冷凝；从第二冷凝器22出来的制冷剂液体经毛细管节流调压后与第一冷凝器21的出口的制冷剂汇合，汇合后的过冷制冷剂经过第三节流装置170变成气液两相状态进入闪发装置30进行气液分离。闪发装置30内的气相制冷剂进入压缩机10的第一吸气口11；液相制冷剂分成两路，一路经第一节流装置150进入第一蒸发器41经换热蒸发成饱和或过热气体被压缩机10的第二吸气口12吸入，另一路经第二节流装置160进入第二蒸发器42经换热蒸发成饱和或过热气体被压缩机10的第三吸气口13吸入。
机械换气装置包括通风装置70，通风装置70包括风机71和加湿结构72等部件，风机71为离心风扇。
加湿结构72包括湿膜721、第一喷淋结构722、第一接水盘723、水泵等部件；或者，加湿结构72可以采用超声波等加湿形式。机械通风的方式通过将自来水水压直接喷向湿膜721，通过离心风扇的风叶转动实现对新风的加湿降温，避免额外的功耗；此外，机械通风加湿通过在新风入口位置处放置湿膜721来实现等焓降温，在满足室内要求的情况下，降低室内的显热负荷，避免长时间开启制冷机组，有利于降低空调***的能耗；同时室外新风的引入能够改善室内空气质量，提升用户体验。
供水管路55将城市用水送到通风装置70的风机71和户外的冷却装置50。采用喷淋的方式分别加湿处理。
室外控制器根据房间不同的参数调整各个部件的运行情况。
