Description

电动汽车及其HAVC空调系统 技术领域
本发明涉及电动汽车技术领域，具体而言，涉及一种电动汽车及其HAVC空调系统。
背景技术
传统内燃机汽车的HAVC(Heating,Ventilating and Air Conditioning；采暖通风与空调)空调系统的冷源、热源由来自发动机余热或由发动机动力驱动，因此非常稳定且其制冷、制热功率非常充足，且几乎不必考虑能耗。
已有的电动汽车的HAVC空调系统通常以传统内燃机汽车的HAVC空调系统为蓝本进行设计，空调系统的结构并无较大改进，空气先流经冷源进行降温，之后控制一定比例的空气经过热源进行加热，由此实现了空气温度的控制。由于压缩机制冷系统特点，存在一个理想的压力状态，系统应在此理想的压力范围进行工作。所以，冷源温度仅在非常小的范围内按照设定值调节(如2℃～5℃，仅举例)，无法满足出风口可调温度的多种需求。此外，对于电动汽车而言，由于在实际的调温中动力电池始终对冷源和热源进行供能，会造成能量的巨大浪费。

具体实施方式
下面详细描述本发明的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本发明，而不能理解为对本发明的限制。
下面参照图1和图2详细描述根据本发明实施例的电动汽车的HAVC空调系统100。
如图1所示，根据本发明第一方面实施例的电动汽车的HAVC空调系统100，包括：箱体10、供热元件20、制冷元件30以及风门40。
箱体10具有进风口11和出风口12，供热元件20位于箱体10内且邻近进风口11设置，制冷元件30位于箱体10内且邻近出风口12设置，制冷元件30与箱体10的内壁共同限定出流通口50，风门40设置在箱体10内且位于供热元件20与制冷元件30之间，风门40用于调节流经通风口50和制冷元件30的空气的比例。
根据本发明第一方面实施例的电动汽车的HAVC空调系统100，根据空调的工作模式控制制冷元件30和/或供热元件20工作，并控制风门40处于合适位置以满足不同工作模式下对制冷空气的比例需求，这样，空气经进风口11进入箱体10内，先流经供热元件20，之后按一定比例分别流经制冷元件30和通风口，最终经制冷元件30冷却的空气与经通风口流出的未冷却的空气进行混合，并最终经出风口12排向车内，由此不仅增大了出风口处出风温度的可调节范围，而且降低了流经蒸发器的空气量，使压缩机整体停机时间变长或整体转速下降，降低了整车能耗。
根据本发明的一些实施例，风门40被构造成在完全封闭流通口50且完全露出制冷元件30的第一位置与完全打开流通口50且完全覆盖制冷元件30的第二位置之间可切换。具体地，风门40处于第一位置时空气全部经制冷元件30冷却后流向出风口12，风门40处于第二位置时空气不经过制冷元件30制冷而是全部经流通口50直接排出并流向出风口12，风门40在第一位置和第二位置之间的任一位置时，一部分空气经制冷元件30制冷后排出且另一部分空气直接经流通口50排出。由此，通过风门40有效调节了流经制冷元件30与流通口50的空气的比例。
在一些实施例中，空调系统具有控制器，控制器分别与风门40、供热元件20电连接，以分别控制风门40的位置和供热元件20的加热温度。由此，通过控制器控制风门40所处的位置以使流经制冷元件30以及流通口50的空气按所需比例混合，通过控制器根据不同工作模式控制供热元件20调节至合适的加热温度以便于与制冷元件的制冷能力相匹配，满足出风口处出风温度的大范围调节需求。
进一步地，在制冷模式下控制器控制风门40处于第一位置且供热元件20不加热，在制热模式下控制器控制风门40处于第二位置且供热元件20加热。由此，在制冷模式下自然风通过供热元件20后无温度变化，再流经风门40并全部经制冷元件30换热冷却后流向出风口12，供热元件20的关闭有效降低了空调系统的能耗；在制热模式下，自然风先经供热元件20加热，且由于风门40完全挡住制冷元件30，最大限度减小了风阻，通过调节供热元件20自身的功率就能实现出风口12的温度的调节。
在图1和图2所示的具体实施例中，风门40可枢转地连接在箱体10的内壁上。参照图1和图2所示，风门40在第一位置与第二位置之间可转动，风门40自第一位置转动至第二位置的转动角度为180度，风门40自第一位置向第二位置转动时，越靠近第二位置，流经制冷元件 30的空气比例越大，流经流通口50的空气比例越小。由此，风门40的结构简单紧凑，方便调节。
根据本发明的一些实施例，还包括用于驱动风门40转动的机械驱动元件或电控元件。由此，通过机械驱动元件或电控元件对风门40进行驱动，以使风门40处于合适位置进而控制进入制冷元件30换热冷却的风与经流通口50流出的风按一定比例混合，最终使出风口12处的风达到预设温度。
可选地，进风口11与出风口12在箱体10的轴向上相对，风门40的枢转轴与箱体10的轴向互相垂直。由此，空调系统的结构更紧凑，布置更合理。
在图1和图2所示的具体实施例中，供热元件20在轴向上完全封盖箱体10的内壁，供热元件20具有供空气流通的换热通道。由此，经进风口11进入的空气经换热通道被快速加热，便于制热模式下空调系统的快速升温。
在一个具体实施例中，制冷元件30为蒸发器，供热元件20为PTC加热器。制冷元件30内设有制冷剂，制冷剂与流经蒸发器的空气进行换热以对空气进行降温冷却。
根据本发明第二方面实施例的电动汽车包括上述实施例的HAVC空调系统100。该电动汽车不仅更节能，而且成本低，空调系统的出风温度的可调节范围更广。
