具体实施方式
结合参见图1至图2所示，根据本申请的实施例，空调系统包括压缩机1、温度调节系统2和除湿系统3，温度调节系统2和除湿系统3并联设置后与压缩机1串联，温度调节系统2与压缩机1通过管路连接形成温度调节循环，除湿系统3与压缩机1通过管路连接形成除湿循环。
本申请的空调系统，除湿系统3和温度调节系统2共用一个压缩机1，因此能够通过一个压缩机1同时为温度调节和除湿提供动力，实现室内的除湿和温度调节，取消了单独的除湿压缩机，减少了压缩机的使用数量，可以使得空调系统结构更加紧凑，降低了空调系统的成本。
本申请的空调系统尤其适用于PTAC(Packaged Terminal Air Conditioner封装式终端空调)空调。
压缩机1的排气口通过第一流量分配装置4分别与温度调节系统2和除湿系统3的第一端连接；和/或，压缩机1的吸气口通过第二流量分配装置5分别与温度调节系统2和除湿系统3的第二端连接。分流器主要用于对冷媒进行分流。压缩机1的排气口通过第一流量分配装置4进行分流，使得冷媒可以更加合理地分配至温度调节系统2和除湿系统3中，流经温度调节系统2和除湿系统3的冷媒，在第二流量分配装置5处又通过第二流量分配装置5汇聚在一处，然后回流至压缩机1的吸气口，完成冷媒的循环流动。第一流量分配装置4可以将压缩机1的排气按照一定比例分别输送到两套系统中。第一流量分配装置4例如为第一分流器，第二流量分配装置5例如为第一分流器。
在本申请中，温度调节系统2包括主室外换热器6、主节流装置7和主室内换热器8，主室外换热器6连接至第一流量分配装置4，主室内换热器8连接至第二流量分配装置5，主节流装置7位于主室外换热器6和主室内换热器8之间。对于本申请的空调系统而言，由于除湿主要应用与制冷环境下，因此，本申请的温度调节系统只需要满足制冷调节即可，可以省去四通阀等结构，简 化空调系统的控制结构，降低空调系统的控制难度，同时也可以在高温潮湿环境中进行有效的除湿制冷，节省空调系统成本。
温度调节系统2包括主室外换热器6、主节流装置7、四通阀和主室内换热器8，四通阀的第一接口连接至第一流量分配装置4，四通阀的第二接口连接至主室外换热器6，四通阀的第三接口连接至主室内换热器8，四通阀的第四接口连接至第二流量分配装置5，主节流装置7位于主室外换热器6和主室内换热器8之间。在本实施例中，基于温度调节具有制冷调节和制热调节两种不同调节工况的情况，增加了四通阀来控制温度调节系统2的换向控制，从而在保证除湿系统正常除湿的情况下，使得温度调节系统可以根据控制需要进行制冷或者制热，既能够实现制冷除湿功能，也能够实现制热除湿功能，功能更加多样化，可以适用于一些特殊的环境下。
除湿系统3包括除湿冷凝器9、除湿节流装置10和除湿蒸发器11，除湿冷凝器9连接至第一流量分配装置4，除湿蒸发器11连接至第二流量分配装置5，除湿节流装置10位于除湿冷凝器9和除湿蒸发器11之间。
除湿系统3还包括设置在除湿冷凝器9和第一流量分配装置4之间的控制阀12，控制阀12用于控制除湿系统3的管路通断。对于不同的季节或者不同的地区，可能会出现并不需要除湿的现象，在此情况下，如果仍然强制进行除湿，就会导致室内过于干燥，影响用户使用舒适度，同时还会增加压缩机1的运行功率，加大压缩机1的功耗，不利于实现节能。因此，在此情况下，增加了能够控制除湿系统3管路通断的控制阀12，可以在需要进行除湿时控制控制阀12打开通道，使得除湿系统3正常除湿。在无需除湿时控制控制阀12关闭通道，使得除湿系统3无需进行除湿，节省能源。该控制阀12例如为电磁阀。
优选地，除湿系统3还包括设置在除湿冷凝器9和第一流量分配装置4之间的流量调节装置13。该流量调节装置能够调节进入除湿系统3的冷媒流量，从而根据室内湿度合理调节除湿量，使得室内湿度能够处于用户所需范围内，更好地满足用户的室内温湿度要求。
第二流量分配装置5与压缩机1的吸气口之间设置有气液分离器14。
优选地，对于PTAC空调而言，空调系统包括室外部分和室内部分，室外部分和室内部分通过隔板15隔开，温度调节系统2包括主室外换热器6、主节流装置7和主室内换热器8，除湿系统3包括除湿冷凝器9、除湿节流装置10和除湿蒸发器11，主室外换热器6设置在室外部分，压缩机1设置在主室外换热器6和隔板15之间，除湿冷凝器9和除湿蒸发器11设置在隔板15靠近室 外部分的一侧。
在本实施例中，室外部分和室内部分均设置在底座上，室外部分位于墙外侧，室内部分位于室内侧，室外部分和室内部分之间还包括位于墙体内的空腔，压缩机1、节流装置和除湿系统3均可以设置在该空腔内，从而能够更加合理地利用空调结构特点实现结构布置，更加充分利用空间，减小空间占用，使得空调结构更加紧凑，布局更加合理。由于除湿系统3需要对空气进行除湿，之后空气才会进入到室内侧进行温度调节，因此将除湿系统3设置在隔板15靠近室外部分的一侧，能够使得除湿系统3更加方便进行除湿。
优选地，除湿冷凝器9和除湿蒸发器11设置在室内部分的进风口处，且除湿蒸发器11和除湿冷凝器9沿着气流流动方向依次并排设置。在进行除湿的过程中，空气首先流经除湿蒸发器11，在除湿蒸发器11的表面进行冷凝，去除空气中的水分，除湿之后的空气经除湿冷凝器9加热，避免了空气温度过低导致的主室内换热器8无法吸收足够热量的问题。
除湿蒸发器11的进风侧设置有除湿过滤网16，可以对进入除湿蒸发器11的空气进行过滤，避免杂质等进入到除湿蒸发器11，同时也能够避免虫鼠等经进风侧进入到室内部分。
在室内部分的进风口还设置有除湿风机17，除湿风机17设置在除湿蒸发器11远离除湿冷凝器9的一侧，用于使得室外空气顺利经室内部分的进风口进入除湿蒸发器11进行冷凝除湿。
在室内部分对应于主室内换热器8还设置有室内风机，室内风机例如为贯流风机18，能够使得空气在与主室内换热器8换热之后，被吹送至室内，对室内温度进行调节。
在上述的空调系统工作时，冷媒自压缩机1的排气口排出后，经冷媒管路进入到第一流量分配装置4处进行流量分配，第一流量分配装置4具有两个分路，冷媒经第一分路进入到主室外换热器6，然后经主节流装置7、主室内换热器8后，进入第二流量分配装置5，然后经冷媒管路流经气液分离器14后，进入压缩机1，完成制冷系统循环。
冷媒经底二分录进入到除湿冷凝器9，然后经除湿节流装置10和除湿蒸发器11之后，进入到第二流量分配装置5，然后经冷媒管路流经气液分离器14后，进入压缩机1，完成制冷系统循环。
在空调系统运转过程中，室外空气由于除湿风机17的作用，先通过除湿风机17，然后经过除湿过滤网16进行过滤，然后通过除湿蒸发器11、除湿冷 凝器9，再通过隔板15进入到室内侧，在贯流风叶的作用下，先通过蜗壳中预留的空隙，然后通过室内风道系统排出。空气经过除湿蒸发器11时，因除湿蒸发器11表面文顿低，低于空气的露点温度，因此可以把空气中的水分冷却，冷却水可以通过排水系统排到室外底盘。空气经过除湿蒸发器11后，空气中的水分被除去，然后除湿后的空气经除湿冷凝器9加热，之后进入到室内。
上述的压缩机1可以为变频压缩机，也可以为定频压缩机。上述的节流装置可以为电子膨胀阀。上述的流量调节装置可以为电子膨胀阀或者短管。上述的电磁阀可以为截止阀或二通阀。
本领域的技术人员容易理解的是，在不冲突的前提下，上述各有利方式可以自由地组合、叠加。
以上仅为本申请的较佳实施例而已，并不用以限制本申请，凡在本申请的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本申请的保护范围之内。以上仅是本申请的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请技术原理的前提下，还可以做出若干改进和变型，这些改进和变型也应视为本申请的保护范围。
