现有的房车空调运行时仅循环室内空气,长时间运行,存在室内空气污浊、二氧化碳含量增加及易滋生细菌等问题。
为了解决上述问题,本实施例公开了一种房车的空调系统,其包括房车空调和新风组件。房车空调包括室内机和室外机,其中室内机设置在房车内部,室外机设置在房车外部。其中室内机包括室内风机和室内换热器,室内风机能够从室内机的回风口吸风,然后在室内换热器处换热之后从室内机的出风口吹出。
房车在室内机的回风口旁设置有安装孔;具体地,房车在室内机的回风口及其周边区域设置有衬垫1,安装孔开设在衬垫1上。该衬垫1具有一定的厚度和宽度,且具有一定的致密度,目的是便于开设安装孔,及布设后续的管件。
新风组件包括新风管2、第一过滤装置3和第二过滤装置4;其中,新风管2穿设于安装孔设置,且固定在衬垫1上。新风管2上设
置有开关组件,其用于控制新风管2是否开启;开关组件具体可以为设置在新风管2上的电磁阀,通过控制电磁阀的开闭来控制新风管2是否开启。在其它实施例中,也可以在新风管2上设置有阀片,通过控制阀片的转动来控制阀片是否封堵新风管2,进而控制新风管2的开闭。
第一过滤装置3设置在新风管2在房车外侧的管口上,主要用于过滤从房车外进入房车内的空气。第二过滤装置4设置在新风管2在房车内侧的管口上,主要用于过滤进入室内机的空气。第一过滤装置3和第二过滤装置4的功能和原理相同,不同之处在于设置位置及具体的布设形式。其中第一过滤装置3和第二过滤装置4均能够过滤粉尘,具体可以使进入到房车内的空气满足PM2.5要求;还能够进行杀菌、除臭等,具体可以通过加热除菌,也可以通过紫外线等进行杀菌;可以通过吸附的方式进行除臭。第一过滤装置3和第二过滤装置4具体为家装或车辆等的新风系统常用的过滤装置,具体结构在此不再赘述。
新风组件还包括过滤控制器,其与第一过滤装置3和第二过滤装置4电连接,用于控制第一过滤装置3和第二过滤装置4的运行;过滤控制器设置在第一过滤装置3和第二过滤装置4附近,便于进行电连接。室内风机运行从室内机的回风口吸风,由于气压关系,房车外的空气能够通过第一过滤装置3和新风管2进入到房车内;然后在室内风机的作用下,通过第二过滤装置4、室内机的回风口、室内风机及室内机的出风口将新风吹到房车内,可以增加房车内的含氧量和空气新鲜度。如果房车空调处于运行状态,进入房车内的空气经过室内换热器的冷却或加热,可以使进入房车内的新风的温度比较适宜。
该房车的空调系统还包括控制模块,其用于执行空调系统的控制方法,过滤控制器与控制模块电连接,两者之间可以进行数据传输。
关于过滤控制器需要说明的是尽管本实施例是单独设置,在其他实施例中其也可以集成在控制模块上。
新风管2的电磁阀与过滤控制器电连接,由过滤控制器控制新风管2是否开启。在其它实施例中,新风管2的电磁阀也可以与控制模块电连接,由控制模块来控制新风管2是否开启。
在房车内还设置有检测装置,其用于检测放车内空气的情
况;主要用于检测PM2.5是否超标、二氧化碳浓度是否超标以及细菌是否超标等等。检测装置可以包括多个种类的检测传感器,一个类型的检测传感器检测其中一种参数;而且每个类型的传感器也可以设置多个,分布在房车内的各个位置,以保证检测结果的准确性。检测装置与过滤控制器电连接,过滤控制器根据检测的信息,确定是否开启新风组件。
关于第二过滤装置4需要说明的是,其也可以在房车空调运行时便可以,可以对房车内的空气进行过滤。
如图2所示,该空调系统的控制方法包括如下步骤:
获取空调系统的运行状态及房车内的空气参数,根据空调系统的运行状态及房车内的空气参数,确定是否开启新风组件及室内风机。“根据空调系统的运行状态及房车内的空气参数,确定是否开启新风组件及室内风机”具体包括:
若房车空调处于运行状态,且房车内的空气参数达到预设阈值,则开启新风组件;
若房车空调处于通电状态,房车空调未处于运行状态,且房车内的空气参数达到预设阈值,则开启新风组件及室内风机。
若房车空调处于运行状态,且房车内的空气参数未达到预设阈值,则关闭新风组件;
若房车空调处于通电状态,房车空调未处于运行状态,且房车内的空气参数未达到预设阈值,则关闭新风组件及室内风机。
其中,开启新风组件指的是开启新风管2、第一过滤装置3和第二过滤装置4,关闭新风组件指的是关闭新风管2、第一过滤装置3及第二过滤装置4。空气参数指的是房车内的PM2.5、二氧化碳浓度、细菌浓度及臭味等等,空气参数达到预设阈值指的是上述参数中任何一个参数超标,则代表空气参数达到了预设阈值。空气参数未达到预设阈值指的是上述参数中所有的参数都未超标,则代表空气参数未达到预设阈值。获取空气参数是采用检测装置来检测获取空气的各个参数,并且间隔一段时间之后便获取一次,具体可以间隔5min获取一次,也可以间隔10min或20min获取一次,并反馈至控制模块;以便进行是否开启新风组件及室内风机的控制。

关于开启新风组件和室内风机需要说明的是,尽管上述实施
例中选择的是在空气参数达到预设阈值之后开启;在其它实施例中也可以是选择开机自启动;即房车空调通电之后,立马启动室内风机和新风组件;然后在空气参数未达标时,控制关闭新风组件,及根据房车空调的状态决定是否关闭室内风机。
至此,已经结合附图所示的优选实施方式描述了本发明的技术方案,但是,本领域技术人员容易理解的是,本发明的保护范围显然不局限于这些具体实施方式。在不偏离本发明的原理的前提下,本领域技术人员可以对相关技术特征作出等同的更改或替换,这些更改或替换之后的技术方案都将落入本发明的保护范围之内。
