一、本发明中净化器设有热交换芯体，室外新风和室内回风经过过滤、净化后皆通过热交换芯体，使室外新风在热交换芯体内回收室内回风的能量，从而达到既通风换气又保持室内温、湿度稳定的效果；当装有热交换芯体的新风净化器在夏季制冷期运行时，室外新风从室内回风中获得冷量，使温度降低，同时被室内回风干燥，使室外新风湿度降低；在冬季运行时，室外新风从室内回风中获得热量，使温度升高，同时被室内回风加湿；同时在室外进 风口设置可更换的新风过滤件，能够有效去除室外空气中的各种污染物，使净化器可以在室外空气存在污染的情况下提供清洁、富氧的空气，提高双向新风净化器的适用性；又在室内回风口设置可更换的回风过滤件，避免室内污染的空气进入热交换芯体，保持净化器内部的清洁，延长机器的使用寿命，且维护简单；
二、本发明中在进风风机和回风风机处分别增设进、回风导流板和第一、二导风圈，室内新风和室内回风分别经过进、回风导流板和第一、二导风圈后进入进、回风风机，进、回风风机的输出的风速集中且均匀，压损小，且净化器噪音小；第一导流板的进风侧导流斜板和送风侧导流斜板分别与送风导流主板之间具有第一、二夹角，第二导流板的回风侧导流斜板和回风导流主板之间具有第三夹角，第一、二、三夹角优选角度角度皆为110°，此时室内新风和室内回风皆能顺着进、回风导流板平稳输入，减小压损和噪音；
三、本发明设有门板，门板的一侧与壳体铰接，使门板通过内铰链与壳体紧密贴合，壳体的密封性佳；门板的另一侧与壳体之间装有磁性接近开关，当门板在净化器使用时门板与壳体扣合，磁性接近开关接通，净化器的工作电路接通，当净化器需要更换新的热交换芯体和过滤件时，门板与壳体分开，磁性接近开关断开，净化器的工作电路断开，使用安全性佳；
四、本发明中新风过滤件包括HEPA过滤层与活性炭过滤棉层，HEPA过滤层对直径为0.3微米以下的微粒去除效率可达到99.97％以上，活性炭过滤棉层采用通孔结构的铝蜂窝、塑料蜂窝、纸蜂窝为载体。与传统活性炭过滤网相比，具有更优良的气体动力学性能，体积密度小，比表面积大、吸附效率高，风阻系数小；用于处理含有苯类、酚类、酯类、醇类、醛类等有机气体及恶臭气体和含有微量重金属的各类气体，且对净化后可直接排放，本发明将HEPA过滤层与活性炭过滤棉层复合使用，过滤效果更佳；回风过滤件采用活性炭塑料蜂窝过滤网，体积密度小，比表面积大、吸附效率高，风阻系数小，对室内空气中的苯类、酚类、酯类、醇类、醛类等有机气体及恶臭气体进行吸收，维护净化器内部清洁的同时，避免废气直接排放到空气中破坏环境；
五、本发明采用的热交换芯体由若干层瓦楞纸自下而上依次叠合而成，每相邻两层瓦楞纸的楞向呈90°放置，保证新风孔道与回风孔道互不相通，不会影响进入室内的新风质量，净化效果佳；热交换芯体采用瓦楞纸，工作过程中不会产生冷凝水从而影响机器的运行，延长机器的使用寿命，节省成本；
六、本发明中壳体内部设有PM2.5传感器和CO 2传感器，壳体上设有相对应的监测孔，用于直接监测透过监测孔的室内空气，PM2.5传感器和CO 2传感器的监测数据更精确，净化器的自动控制所依据的参数也更合理，为了便于室内空气进出传感器附近，在壳体的底面开设了大气孔，以使传感器附近的气压保持与大气压一致，设计合理，监测准确；同时，PM2.5传感器和CO 2传感器的外侧设置隔离罩，隔离罩不影响空气流入传感器附近，使PM2.5传感器和CO 2传感器监测的完全是室内的空气，不受室外新风的影响，监测数值精确；
七、本发明中触控屏上的操作按钮包括ON/OFF按键、FAN按键、MODE按键、SLEEP按键、UP按键和DOWN按键，其中SLEEP按键具有自动将进风风机和回风风机的风速调节至低档的功能，人性化设置，设计合理；其中MODE按键用于调节自动控制模式与手动控制模式；且自动控制模式时，净化器控制电路板根据PM2.5传感器和CO 2传感器反馈的数值自动调节进风风机和回风风机的风速，当PM2.5传感器和CO 2传感器的数值高于设定值时，调节进风风机和回风风机至高档，当PM2.5传感器和CO 2传感器的数值低于设置值时，调节进风风机和回风风机至中档或低档；自动化程度高，设计合理。
八、本发明中壳体、电气控制盒和隔离罩皆采用钢制材料，与塑料材质相比，机器更牢固，不易损坏，节省维护与维修成本；
九、本发明中新风过滤件、回风过滤件和热交换芯体皆设计为与壳体可拆卸连接，方便更换与维护；热交换芯体设有提拉布条，方便取出。

本发明的工作原理或工作过程如下：
本发明将室外新风经过过滤、净化和热处理后送进室内，同时又将室内回风经过过滤、净化和热交换处理后排出室外；室外新风和室内回风经过过滤、净化后皆通过热交换芯体，室外新风在热交换芯体内回收室内回风的能量，从而达到既通风换气又保持室内温、湿度稳定的效果；当装有热交换芯体的新风净化器在夏季制冷期运行时，室外新风从室内回风中获得冷量，使温度降低，同时被室内回风干燥，使室外新风湿度降低；在冬季运行时，室外新风从室内回风中获得热量，使温度升高，同时被室内回风加湿；同时在室外进风口设置可更换的新风过滤件，能够有效去除室外空气中的各种污染物，使得新风净化器可以在室外空气存在污染的情况下提供清洁、富氧的空气，提高双向新风净化器的适用性；又在室内回风口设置可更换的回风过滤件，避免室内污染的空气进入热交换芯体，保持新风净化器内部的清洁，延长机 器的使用寿命，且维护简单。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
