空调器及其控制方法
相关申请
本申请要求2019年03月26日申请的，申请号为201910233500.2，名称为“空调器及其控制方法”的中国专利申请的优先权，在此将其全文引入作为参考。
技术领域
本申请属于空气调节技术领域，具体涉及一种空调器及其控制方法。
背景技术
当空调在冬天制热运行时，从室外恶劣环境中很难再吸取环境中的热量，导致外机在运行过程中冷凝器表面开始出现结霜，并且越结越厚，严重影响室外机的换热效率。传统空调器在室外管温低于一定值时，开始进入化霜，此时空调器转为制冷运行，利用高温排气进行化霜；此时，由于空调器转制冷运行，导致室内侧出风温度降低(通常采用关闭内风机形式)，此时影响室内舒适性及用户体验。
相关技术中公开了一种热泵系统及其除霜控制方法，加热装置可对微通道换热器的至少一个集流管进行加热。根据该申请的热泵系统，化霜均匀，可提高化霜效率，除霜过程中系统仍能对室内进行加热，降低了除霜过程室内侧温度变化幅度，提高系统舒适性及除霜效率。但是这种需要增加加热装置进行化霜，不仅增加耗电量，还增加额外零件，成本高，且只适用于微通道换热器。
发明内容
因此，本申请要解决的技术问题在于提供一种空调器及其控制方法，无需增加额外的加热装置，可以充分利用空调器本身余热或废热，提高能源利用率，降低能源耗费。
为了解决上述问题，本申请提供一种空调器，包括室内机和室外机，室内机包括排风管，室外机包括室外换热器，排风管的管口设置在室外换热器的进风区域。
在一实施例中，排风管上设置有排风阀。
在一实施例中，排风管的管口朝向室外换热器的进风侧。
在一实施例中，排风管的管口朝向与室外换热器的进风侧表面相平行。
在一实施例中，排风管的管口位于室外换热器的第一侧边缘，且管口朝向室外换热器的第二侧，该第二侧与第一侧相对。
在一实施例中，室内机和室外机之间连接有连接管，排风管的部分与连接管一起走管包扎。
在一实施例中，连接管上设置有截止阀，排风管与连接管一起走管包扎，并在截止阀的末端分开。
在一实施例中，室内机还包括排风腔，排风腔内设置有排风机，排风管连通至排风腔，排风机用于将室内空气通过排风管排出室内。
在一实施例中，室内机还包括新风腔、新风管和新风机，新风机设置在新风腔内，新风管将新风腔与室外连通。
在一实施例中，新风管上设置有新风阀。
根据本申请的另一方面，提供了一种上述的空调器的控制方法，包括：
控制空调器开启制热模式，检测室外环境温度；
当室外环境温度≤a时，控制室内机通过排风管向室外换热器排出废热空气，对室外换热器进行化霜处理。
在一实施例中，当室外环境温度≤a时，控制室内机通过排风管向室外换热器排出废热空气，对室外换热器进行化霜处理的步骤包括：
检测空调器是否开启新风机；
当未开启新风机时，控制排风机运行，打开排风阀，关闭新风阀；
当开启新风机时，控制排风机运行，打开排风阀和新风阀。
本申请提供的空调器，包括室内机和室外机，室内机包括排风管，室外机包括室外换热器，排风管的管口设置在室外换热器的进风区域。该空调器将室内侧的废气通过排风管排放至室外换热器的进风区域，并经室外换热器与室外换热器进行换热，从而能够有效利用室内空气的废气余热对室外换热器进行加热，实现对室外换热器的化霜处理，实现不停机化霜，而且也能够提高室外换热器的热量吸收，提高室外换热器的蒸发效率，提高能源利用率，降低能源耗费，整个过程直接利用了室内空气余热，因此无需增加额外的加热装置，结构更加简单，成本更低。

具体实施方式
为了便于理解本申请，下面将参照相关附图对本申请进行更全面的描述。附图中给出了本申请的较佳的实施例。但是，本申请可以以许多不同的形式来实现，并不限于本文所描述的实施例。相反地，提供这些实施例的目的是使对本申请的公开内容的理解更加透彻全面。
结合参见图1和图2所示，根据本申请的实施例，空调器包括室内机和室外机，室内机包括排风管1，室外机包括室外换热器2，排风管1的管口设置在室外换热器2的进风区域。
该空调器将室内侧的废气通过排风管1排放至室外换热器2的进风区域，并经室外换热器2与室外换热器2进行换热，从而能够有效利用室内空气的废气余热对室外换热器2进行加热，实现对室外换热器2的化霜处理，实现不停机化霜，而且也能够提高室外换热器2的热量吸收，提高室外换热器2的蒸发效率，提高能源利用率，降低能源耗费，整个过程直接利用了室内空气余热，因此无需增加额外的加热装置，结构更加简单，成本更低。
相对于传统空调器而言，采用本申请的方案，可以延长制热运行时间，尤其是低温制热运行时期，由于温度提高，既提高了室外机的换热效率，又降低了室外换热器2的表面结霜情况；同时使得外管温度提高，从而不进入化霜，大大提高室内侧舒适性。
在一实施例中，排风管1上设置有排风阀6。通过在排风管1上设置排风阀6，可以在无需向室外换热器2送入室内空气时，关闭排风阀6，提高了排风控制的灵活性。该排风阀6可以为电磁阀，通过控制器进行控制，控制器可以为空调器的控制器，从而可以通过空调器根据自身的工况进行合理控制，提高控制精度，降低控制难度。
排风管1的管口设置在室外换热器2的进风区域，当室外机运行时，在室外换热器2的进风区域形成负压，从排风管1的管口吹出的室内空气被吸入到室外换热器2内，从而可以提高室外换热器2的换热效率。当室外换热器2对应的风机不运转时，室内排风可以用于清洁室外换热器2，能够利用排风管1吹出的风将附着在室外换热器2表面的较大的树叶等杂物吹走，避免杂物对室外换热器2形成遮挡，提高室外换热器2的换热效率。
排风管1的管口可以设置在室外换热器2的进风侧的中间位置，或者是边缘位置，只要能够到达室外换热器2所形成的负压区域，并被室外换热器2吸入进行换热即可。
在实际的设计过程中，排风管1与室外换热器2的进风侧之间会存在一定的位置偏差， 因此，为了保证排风管1的管口能够顺利设置在室外换热器2的进风区域，可以对排风管1进行一定的改造，将排风管1设计为弯管，使得排风管1的管口最终能够顺利到达室外换热器2的进风侧，提高排风管1的送风效率。
在其中一个实施例中，排风管1的管口朝向室外换热器2的进风侧。在本实施例中，排风管1的管口的出风方向垂直于室外换热器2的进风侧表面，在该实施例中，排风管1的管口对应于室外换热器2的进风侧表面的中部设置，可以提高进风均匀性。
在另外一个实施例中，排风管1的管口朝向与室外换热器2的进风侧表面相平行。在本实施例中，将排风管1的出风方向设置为与室外换热器2的进风侧表面相平行，是为了避免排风管1的管口直吹室外换热器2造成风压不均的问题，在排风管1从管口将室内空气排出时，此时由于排风管1的出口并非是直对室外换热器2，因此在室内空气排出的过程中，室内空气在进风侧表面的整个平面上相对而言风压是比较均匀的，此时室内空气不会主动进入到室外换热器2内，而是在室外换热器2的负压作用下被吸入，由于室外换热器2的负压在室外换热器2的进风侧表面分布较为均匀，因此能够提高对室内空气吸入压力的均匀性，使得室内空气能够更加均匀地通过室外换热器2，与室外换热器2之间进行换热，有效提高排风管1排出的室内空气与室外换热器2之间的换热均匀性，提高换热效率。
在一实施例中，排风管1的管口位于室外换热器2的第一侧边缘，且管口朝向室外换热器2的第二侧，该第二侧与第一侧相对。由于排风管1内排出的室内空气流经室外换热器2的整个进风侧表面，因此能够在整个进风侧表面分布，便于由室外换热器2的进风区域负压吸入到室外换热器2内进行换热，提高室内空气的利用效率。
室内机和室外机之间连接有连接管3，排风管1的部分与连接管3一起走管包扎。通过将排风管1与连接管3一起走管包扎的方式，能够通过包扎层对排风管1形成保温和保护，避免室内空气在传输至室外换热器2的进风区域的过程中发生较大的热量散失，提高能量利用效率。
在一实施例中，连接管3上设置有截止阀4，排风管1与连接管3一起走管包扎，并在截止阀4的末端分开。排风管1与连接管3在截止阀4的末端分开，各自进行走线，可以使得排风管1根据室外机自身结构进行布管调整，增强排风管1布管设置的灵活性，有效避免排风管1布管过程中与其他结构发生干涉，同时可以使得排风管1的布管不受连接管3的走管影响，能够选取较优的走管路线。
室内机还包括排风腔，排风腔内设置有排风机5，排风管1连通至排风腔，排风机5用于将室内空气通过排风管1排出室内。
室内机还包括新风腔、新风管9和新风机7，新风机7设置在新风腔内，新风管9将新风腔与室外连通。新风腔和排风腔之间通过隔板隔开，能够避免新风腔内的新风与排风腔内的排风混合，提高新风系统的换风效率。
新风管9上设置有新风阀8。在一实施例中，隔板上还可以设置用于连通新风腔和排风腔的内循环风阀，在需要进行内循环时，可以关闭排风阀6和新风阀8，同时打开新风机7和排风机5，实现空气内循环流动。
结合参见图2所示，根据本申请的实施例，上述的空调器的控制方法包括：控制空调器开启制热模式，检测室外环境温度；当室外环境温度≤a时，控制室内机通过排风管1向室外换热器2排出废热空气，对室外换热器2进行化霜处理。此处的a例如为0℃，也可以根据地域和海拔高度等对该室外环境温度进行适应性的调节。
在一实施例中，当室外环境温度≤a时，控制室内机通过排风管1向室外换热器2排出废热空气，对室外换热器2进行化霜处理的步骤包括：检测空调器是否开启新风机7；当未开启新风机7时，控制排风机5运行，打开排风阀6，关闭新风阀8，这时，室内侧温度较高的废热空气吹向室外换热器2，将室外换热器2表面霜层化掉。
当开启新风机7时，控制排风机5运行，打开排风阀6和新风阀8，此时排风口排出的温度较高的室内余热空气对室外换热器2加热，将室外换热器2表面霜层化掉。
通过上述的控制方式，能够在空调器处于制热工况时，尤其是低温制热工况时，能够利用室内排出的空气预热对室外换热器2进行加热，一方面进行化霜，避免室外换热器2的表面结霜，保证室外换热器2的换热效率，另一方面能够充分利用室内空气的废气余热提高室外换热器2的温度，提高热量利用效率。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
