Description

冷暧空调器 技术领域
本发明涉及冷暖空调器。 背景技术
目前冷暖空调器的节流装置主要可分为毛细管节流装置和膨胀 阀节流装置， 毛细管节流装置一般由一根（或一組）毛细管构成， 或 一根（或一組）毛细管和另一根（或一组）与一个单向阀并联的毛细管 串联抅成， 前者在制冷工况与制热工况运行时都使用相同的毛细管 节流， 这样空调器就无法在两种工况下都达到最佳的工作状况， 同 时在对空调器进行优化设计时也无法同时兼顾两种不同工况； 后者 虽然可以通过单向阀的调控来使空调器在制冷工况和制热工况时使 用不同长度的毛细管进行节流， 但是由于这两根（或两組）毛细管是 串联连接， 不便于对空调器的制冷工况和制热工况分别进行独立的 优化设计。 采用膨胀阀节流装置， 同样也存在对空调器进行优化设 计时无法同时兼顾两种不同工况的问题。 发明内容
本发明的目的在于克服上述现有技术中存在的缺陷， 提供一种 结构新型、 性能优良、 降低能耗的冷暖空调器。
为实现本发明的上述目的， 本发明提供了一种冷暖空调器， 包 括压缩机、 室外换热器、 室内换热器和四通换向阀， 其特征在于还 包含并联毛细管装置， 其中并联毛细管装置与室内、外换热器相连， 所述并联毛细管装置由一个两位三通电磁阀或两个导通方向相反的 单向阀与两组并联的毛细管組成。
所述并联毛细管可分别包含一根或多根串联而成的具有不同尺 寸、 结构的毛细管， 并可以在各自串联的毛细管之间串联诸如气液 分离器、 油液分离器一系列热工装置， 毛细管的尺寸和结构可以根 据不同类型的冷暖空调器来进行选择。 在制冷或制热工况下， 可根 据采用的两位三通切换阀或分别处于不同的通阻状态的单向阀来选 择不同的毛细管进行节流。
为实现本发明的上述目的， 本发明还提供了一种冷暖空调器， 包括压缩机、 室外换热器、 室内换热器和四通换向阀， 其特征在于 还包含并联膨胀阀装置， 其中并联膨胀阀装置与室内、 外换热器相 连， 所述并联膨胀阀装置由一个两位三通电磁阀或两个导通方向相 反的单向阀与两組并联的膨胀阀组成。
膨胀阀可以相同或不同， 并可以在各自串联的膨胀阀之间串联 诸如气液分离器、 油液分离器一系列热工装置， 膨胀阀的类型可根 据不同类型的冷暖空调器来进行选择。 在制冷或制热工况下， 可根 据采用的两位三通切换阀或分别处于不同的通阻状态的单向阀来选 择不同的膨胀阀进行节流。 市售的各种类型的膨胀阀均可以使用。
为实现本发明的上述目的， 本发明还提供了一种冷暖空调器， 包括压缩机、 室外换热器、 室内换热器和四通换向阀， 其特征在于 还包含并联毛细管和膨胀阀组合的装置， 其中并联毛细管和膨胀阀 组合的装置与室内、 外换热器相连， 所述并联毛细管和膨胀阀组合 的装置由一个两位三通电磁阀或两个导通方向相反的单向阀与并联 的一组毛细管和一组膨胀阀组合而成。
为实现本发明的上述目的， 本发明还提供了一种冷暖空调器， 包括压缩机、 室外换热器、 室内换热器和四通换向阀， 其特征在于 还包含并联毛细管和膨胀阀组合的装置， 其中并联毛细管和膨胀阀 组合的裝置与室内、 外换热器相连， 所述并联毛细管和膨胀阀组合 的装置由一个两位三通电磁阈或两个导通方向相反的单向阀与并联 的两组毛细管和膨胀阀串联的組合件组合而成。 在本发明的冷暖空调器中， 毛细管和膨胀阀的数目都可以是一 个或多个。
由一个或一组毛细管与一个或一组膨胀阀并联而成的组合裝置 或由一个或多个毛细管和膨胀阀相互串联再并联而成的组合装置兼 备毛细管和膨胀阀的特点， 从而起到一个协同效应， 使性能更优良， 同时还可以在各自串联的毛细管或膨胀阀之间串联诸如气液分离 器、 油液分离器一系列热工装置。 在制冷或制热工况下， 可根据采 用的两位三通切换阀或分别处于不同的通阻状态的单向阀来选择不 同的毛细管和膨胀阀的组合进行节流。
本发明提供的一种新型冷暖空调器， 包括压缩机、 室外换热器、 室内换热器和四通换向阀， 其特征在于还包含并联毛细管装置、 并 联膨胀阀装置或并联毛细管和膨胀阀組合的装置， 其中并联毛细管 装置、 并联膨胀阀装置或毛细管和膨胀阀串联的组合件再并联的的 装置与室内、 外换热器分别相连。 由于在冷暖空调器中采用并联的 毛细管装置、 并联的膨胀阀装置或毛细管和膨胀阀串联的组合件再 并联的装置，在制冷工况和制热工况时分别单独使用其中的一根（或 一組）毛细管、一个（或一组）膨胀阀或一个毛细管和膨胀阀组合件进 行节流， 两根（或两組）毛细管、 两个（或两组）膨胀阀或两个毛细管 和膨胀阀串联的组合件独立工作， 互不干涉。 从而可以满足对空调 器制冷工况和制热工况分别进行独立优化设计的要求， 以达到性能 优良、 降低能耗、提高效率的目的。
