技术领域
本申请涉及空调器技术领域，尤其涉及一种空调器的新风控制方法及装置。
背景技术
空调器是一种广泛应用的家用电器，一般具有制热和制冷功能。在环境温度过低或过高时，空调器可对室内空气的温度进行调节，为用户提供一个适宜的室内环境，有效地提高用户的生活品质。
然而，现有空调器在制热或制冷时，只是对室内的空气进行循环加热或降温，用户为了保持室内的温度，会将居室的门窗同时关闭，导致室内的空气质量逐渐变差，对用户的身体健康造成不利影响。特别地，随着大气污染的日益加剧，尤其在冬季供暖季节，用户大多不愿开窗通风，导致室内空气质量会越来越差，含氧量越来越低，影响到用户身体健康。
目前，空调器引入新风装置后，在启用新风功能时，尽管改善了室内空气质量，但是，同样对室内环境温度造成较大的影响。在空调制热能力不变的前提下，空调运行时需要更长的时间才能到达用户设定的温度，会使得制热效果变差，影响到用户体验。

具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请中的附图，对本申请中的技术方案进行清楚、完整地描述，显然，所描述的 实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
下面结合图1-图7描述本申请的一种空调器的新风控制方法及装置。
如图1所示，本实施例提供一种空调器的新风控制方法，包括：
步骤110，获取空调器的作用空间内的环境温度与二氧化碳浓度。
步骤120，根据二氧化碳浓度，确定第一换热风送装置与第二换热风送装置的开启状态。
步骤130，若环境温度与设定温度的温差值处于第一换热风送装置与第二换热风送装置的换热能力范围内，根据所述开启状态，控制第一换热风送装置与第二换热风送装置。
具体地，本实施例通过获取空调器的作用空间内的环境温度与二氧化碳浓度，基于对二氧化碳浓度及环境温度与设定温度的温差值的判定，可对第一换热风送装置与第二换热风送装置的开启状态进行控制，既可通过向室内环境送新风的方式改善室内空气质量，又确保了对室内环境的换热效率，提升了用户体验。
在此应指出的是，第一换热风送装置与第二换热风送装置的换热能力范围，是指第一换热风送装置或第二换热风送装置通过热交换的方式，将单位体积的空气从第一预设温度调节至第二预设温度的能力。
显然，在环境温度与设定温度的温差值较小时，该温差值可能处于第一换热风送装置或第二换热风送装置的换热能力范围内，此时，单独开启第一换热风送装置与第二换热风送装置当中的任一者，均能实现对室内温度的快速调节；相应地，在环境温度与设定温度的温差值较大时，该温差值可能处于第一换热风送装置或第二换热风送装置的换热能力范围外，此时，单独开启第一换热风送装置与第二换热风送装置当中的任一者，并不能满足对室内温度的快速调节要求。
与此同时，本实施例可通过设于空调器的进风口的温度传感器检测空调器的作用空间内的环境温度，并通过设于空调器的进风口的二氧化碳浓度传感器检测空调器的作用空间内的二氧化碳浓度。本实施例所示的空调器既可以为壁挂式空调器，也可以是柜式空调器。
如图2至图5所示，本实施例所示的空调器包括机壳1；机壳1的壳壁上设有室内进风口2、新风入口3及出风口4；第一换热风送装置5与第二换热风送装置6设于机壳1内；第一换热风送装置5的一端与室内进风口2连通，第二换热风送装置6的一端与新风入口3连通，第一换热风送装置5的另一端及第二换热风送装置6的另一端分别与出风口4连通。其中，新风入口3用于与新风管9的一端连通，新风管9的另一端用于与室外环境连通。
其中，本实施例在启动第一换热风送装置5时，第一换热风送装置5用于从室内进风口2吸风，以对室内(空调器的作用空间)的空气进行制冷或制热处理，处理后的空气通过出风口4排向室内。
相应地，本实施例在启动第二换热风送装置6时，第二换热风送装置6用于从新风入口3吸风，以对室外的新鲜空气进行制冷或制热处理，处理后的空气通过出风口4排向室内。如此，基于第二换热风送装置6对室外新风的换热与风送处理，既可确保输入至室内新风的温度，又可有效地降低室内环境的二氧化碳浓度，提升了用户体验。
如图2所示，本实施例所示的第一换热风送装置5包括第一换热器51、第一风机52及第一风道53；第一换热器51的第一侧面朝向室内进风口2，第一换热器51的第二侧面朝向第一风道53的第一端口，第一风道53的第二端口与出风口4连通；第一风机52设于第一风道53内；第二换热风送装置6包括第二换热器61、第二风机62及第二风道63；第二换热器61的第一侧面朝向新风入口3，第二换热器61的第二侧面朝向第二风道63的第一端口，第二风道63的第二端口与出风口4连通；第二风机62设于第二风道63内。
进一步地，本实施例所示的第一风机52与第二风机62当中至少一者为离心风扇；在第一风机52为离心风扇的情况下，第一风道53呈蜗壳状；在第二风机62为离心风扇的情况下，第二风道63呈蜗壳状。
其中，为了提升风送效率，减小对空调内部空间的占用，本实施例所示的第一风机52与第二风机62优选为离心风扇。在第一风机52与第二风机62设计为离心风扇的情况下，本实施例所示的第一风道53与第二风道63均相应地设计呈蜗壳状。
与此同时，本实施例所示的第一风机52与第二风机62在输入一定的电流的情况下，即可启动运行。由于本实施例所示的第一换热器51与第二换热器61分别通过制冷剂管路与空调外机的冷凝器连通，从可通过控制第一换热器51与第二换热器61相应连接管路上的控制阀开启，以实现启动第一换热器51与第二换热器61的制冷或制热运行。
优选地，为了实现对室内环境的送新风控制，本实施例所示的根据二氧化碳浓度，确定第一换热风送装置与第二换热风送装置的开启状态，包括但不限于如下步骤：
在二氧化碳浓度处于安全阈值范围内的情况下，控制开启第一换热风送装置，关闭第二换热风送装置。如此，本实施例在二氧化碳浓度处于安全阈值范围内，可通过第一换热风送装置对室内环境进行正常地制冷或制热处理，此时，由于二氧化碳浓度符合家居人员的正常生活要求，无需开启第二换热风送装置。
相应地，在二氧化碳浓度高于安全阈值范围的最大值的情况下，控制开启第二换热风送装置，关闭第一换热风送装置。此时，由于二氧化碳浓度过高，可能影响到家居人员的正常生活要求，此时，可单独开启第二换热风送装置，以向室内室内输送经过热交换处理后的新风，既可确保输入至室内新风的温度，又可有效地降低室内环境的二氧化碳浓度，提升了用户体验。
其中，根据人体对二氧化碳浓度的适应性程度，本实施例所示的二氧化碳浓度的安全阈值范围可设置为0.01％-0.4％。
进一步地，本实施例所示的在二氧化碳浓度高于安全阈值范围的最大值的情况下，控制开启第二换热风送装置，进一步包括：
根据二氧化碳浓度，确定第二换热风送装置进行风送的目标风速；根据目标风速，控制第二换热风送装置。
具体地，在二氧化碳浓度过高时，为了尽快降低室内的二氧化碳浓度，本实施例可设置目标风速为高风速，并控制第二换热风送装置的第二风机以高风速运行，以增大向室内送新风的风量。
在二氧化碳浓度相对较低时，例如：二氧化碳浓度接近安全阈值范围的最小值，本实施例可设置目标风速为低风速，并控制第二换热风送装置 的第二风机以低风速运行，以降低向室内送新风的风量。
优选地，本实施例所示的空调器的新风控制方法，还包括：在环境温度与设定温度的温差值大于预设值的情况下，控制同时开启第一换热风送装置与第二换热风送装置。
具体地，在环境温度与设定温度的温差值大于预设值时，可判定该温差值可能处于第一换热风送装置或第二换热风送装置的换热能力范围外，此时，由于单独开启第一换热风送装置与第二换热风送装置当中的任一者，均不能满足对室内温度的快速调节要求，则可同时开启第一换热风送装置与第二换热风送装置，以在对室内温度进行快速调节的同时，还通过送新风降低室内空气中的二氧化碳浓度。
如图2与图5所示，本实施例所示的出风口4设有出风调控装置，出风调控装置具有闭合出风口4的第一状态与打开出风口4的第二状态。
具体地，在本实施例所示的空调器具体为空调柜机的情况下，为了实现对出风口4的开闭控制，本实施例所示的出风调控装置包括挡风板10与直线驱动机构；直线驱动机构的驱动端与挡风板10连接，以驱动挡风板10沿空调柜机的高度方向移动。在出风调控装置处于第一状态时，挡风板10遮挡于出风口4；在出风调控装置处于第二状态时，挡风板10与出风口4分离。其中，本实施例所示的直线驱动机构在图2与图5中未具体示意出。
进一步地，本实施例可在机壳1上设置滑轨，滑轨沿着机壳1的高度方向排布。本实施例所示的挡风板10可滑动的安装于滑轨上，并可在滑轨的引导下沿机壳1的高度方向稳定地上下移动。
与此同时，为了便于实现对挡风板10的移动控制，本实施例所示的直线驱动机构优选为电动推杆或丝杠驱动机构。其中，本实施例可具体设置直线驱动机构的驱动端与挡风板10的下端连接。直线驱动机构的驱动端可沿机壳1的高度方向上下移动，且直线驱动机构的驱动端连接于挡风板10的背面。
如图2与图3所示，为了对第一换热风送装置5的第一换热器51形成物理性防护，并对进入机壳1内的空气进行初步净化处理，本实施例在室内进风口2设有进风格栅7。
相应地，为了对第二换热风送装置6的第二换热器61形成物理性防护，并对进入机壳1内的空气进行初步净化处理，本实施例在第二换热器61与新风入口3之间设有空气净化结构8。其中，空气净化结构8优选为本领域公知的HEPA滤网。
进一步地，为了便捷地对第一换热风送装置的第一换热器及第二换热风送装置的第二换热器上附着的灰尘进行清理，本实施例所示的方法包括但不限于如下步骤：
步骤101，检测空调器的运行状态。
步骤102，在运行状态满足预设条件的情况下，控制出风调控装置处于第一状态，控制第一换热风送装置从室内进风口吸风，且第二换热风送装置朝向新风入口送风，或者控制第一换热风送装置朝向室内进风口送风，且第二换热风送装置从新风入口吸风。
其中，预设条件包括空调器接收到开机指令信号、空调器接收到关机指令信号及空调器的运行时间大于第一预设时长当中的任一种。
具体地，由于在出风口关闭时，第一换热风送装置的另一端与第二换热风送装置的另一端相连通，则通过控制第一换热风送装置与第二换热风送装置以相反的方向送风，可便捷地对第一换热风送装置的第一换热器及第二换热风送装置的第二换热器上附着的灰尘进行反向吹扫。
本实施例在控制第一换热风送装置从室内进风口吸风时，可控制第一换热风送装置的第一风机以第一旋向运转，在控制第一换热风送装置朝向室内进风口送风时，可控制第一换热风送装置的第一风机以第二旋向运转，且第一旋向与第二旋向的旋转方向相反。
相应地，本实施例在控制第二换热风送装置从新风入口吸风时，可控制第二换热风送装置的第二风机以第一旋向运转，在控制第二换热风送装置朝向新风入口送风时，可控制第二换热风送装置的第二风机以第二旋向运转。
基于本实施例所示的方法的控制逻辑，本实施例既可在空调器开机时，对第一换热器与第二换热器分别进行一次反向吹扫，也可在空调器关机时，对第一换热器与第二换热器分别进行一次反向吹扫，还可在空调器的运行时间大于第一预设时长时，对第一换热器与第二换热器分别进行一次反向 吹扫，以达到较好的清扫效果。
其中，本实施例所示的第一预设时长可以为6-12小时，例如：第一预设时长具体为6小时、8小时、10小时、12小时，对此不作具体限定。
如图6所示，本实施例还提供一种空调器的新风控制装置，包括：
获取模块610，用于获取空调器的作用空间内的环境温度与二氧化碳浓度。
确定模块620，用于根据二氧化碳浓度，确定第一换热风送装置与第二换热风送装置的开启状态。
控制模块630，用于若环境温度与设定温度的温差值处于第一换热风送装置与第二换热风送装置的换热能力范围内，根据开启状态，控制第一换热风送装置与第二换热风送装置。
其中，空调器包括机壳；机壳的壳壁上设有室内进风口、新风入口及出风口；第一换热风送装置与第二换热风送装置设于机壳内；第一换热风送装置的一端与室内进风口连通，第二换热风送装置的一端与新风入口连通，第一换热风送装置的另一端及第二换热风送装置的另一端分别与出风口连通。
具体地，本实施例通过获取空调器的作用空间内的环境温度与二氧化碳浓度，基于对二氧化碳浓度及环境温度与设定温度的温差值的判定，可对第一换热风送装置与第二换热风送装置的开启状态进行控制，既可通过向室内环境送新风的方式改善室内空气质量，又确保室内环境的换热效果，提升了用户体验。
