Description

一种高温CO2空气源热泵的隔离病房排风系统
技术领域
本发明涉及空气调节与高温杀毒的技术领域，更具体地，涉及一种高温CO2空气源热泵的隔离病房排风系统。
背景技术
隔离病房一直用于隔离患有传染病尤其是呼吸系统传染病的病患。负压隔离病房的排风系统根据GB/T35428-2017《医院负压隔离病房环境控制要求》而设计，保证排出的空气对周围环境没有污染。传统的电加热等方式能耗较高，传统的有机工质热泵会产生污染物泄漏的危险，并且制冷剂相变对设备的要求也更高。
因此，现有技术中亟需一种在完善病房的排气系统的同时，对污染气体作出有效处理，不仅节约能源，而且更好地保护了医护人员的安的隔离病房排风系统全。
发明内容
针对上述现有技术的不足，本发明提供了一种将高温CO2空气热泵装置附加在负压隔离病房的排气系统上的高温CO2空气源热泵的隔离病房排风系统。
为实现上述目的，本发明通过下述技术方案予以实现：
一种高温CO2空气源热泵的隔离病房排风系统，包括与隔离病房相连通的进风口和出风口，与所述进风口连通的进风管道内依次设置有供风扇、过滤器、气体冷却器和中间换热器，与所述出风口连通的出风管道内依次设置有风机、紫外线荧光灯、蒸发器和排风扇，所述中间换热器位于所述进风管道与所述出风管道的交汇处、所述蒸发器和所述排风扇之间的位置，所述蒸发器的工质出口连接CO2压缩机，所述CO2压缩机的工质出口与所述气体冷却器的工质进口连接，所述气体冷却器的工质出口连接有节流阀，所述节流阀的工质出口与所述蒸发器的工质进口连接。
所述蒸发器下方设置有排水口。
所述中间换热器为全热换热器。
所述过滤器为活性炭过滤器。
本发明与现有技术相比的有益效果是：将高温CO2空气热泵装置附加在负压隔离病房的排气系统上，在完善病房的排气系统的同时，对污染气体作出有效处理，不仅节约能源，而且更好地保护了医护人员的安全；通过热泵加热空气以消毒相比传统加热方式可有效节约能源，利用传感器和控制器实现闭环，可以达到自动控制的目的，在热泵加热消毒效果不足时，自动开启电加热器加热空气有效提高消毒效果；CO2空气源热泵与其他的工作原理相同，都是蒸汽压缩式热泵，但稍有不同的是，CO2热泵属于超临界循环，即在冷凝器端，CO2是不会被冷凝成液态的，提高了热泵系统的COP。
附图说明
图1是本发明的系统图。
附图标记：1-供风扇，2-过滤器，3-节流阀，4-气体冷却器，5-CO2压缩机，6-蒸发器，7-中间换热器，8-排风扇，9-排水口，10-紫外线荧光灯，11-风机，12-进风口，13-出风口，14-隔离病房。
具体实施方式
下面根据具体实施方式对本发明做进一步阐述。
如图1所示的高温CO2空气源热泵的隔离病房排风系统，包括与隔离病房14相连通的进风口12和出风口13，与进风口12连通的进风管道内依次设置有供风扇1、过滤器2、气体冷却器4和中间换热器7，中间换热器7为全热换热器，过滤器2为活性炭过滤器。与出风口13连通的出风管道内依次设置有风机11、紫外线荧光灯10、蒸发器6和排风扇8，中间换热器7位于进风管道与出风管道的交汇处、蒸发器6和排风扇8之间的位置，蒸发器6的工质出口连接CO2压缩机5，CO2压缩机5的工质出口与气体冷却器4的工质进口连接，气体冷却器4的工质出口连接有节流阀3，节流阀3的工质出口与蒸发器6的工质进口连接。CO2工质在蒸发器6、CO2压缩机5、气体冷却器4和节流阀3中循环，构成了CO2空气源热泵。为将热泵系统的冷凝水排出出风管道，在蒸发器6下方设置有排水口9，冷凝水通过排水口9流出管道，并通过集水盘等方式收集并排出。
本发明的工作过程如下：室外新鲜的冷空气通过供风扇1的作用进入进风管道，经过过滤器2过滤，再经全热换热器7，通过进风口12进入隔离病房14。隔离病房14中的室内浑浊空气在风机11的作用下通过出风口13，经紫外线荧光灯10消毒，再经蒸发器6，浑浊空气的热量被蒸发器6中的二氧化碳工质吸收，再经中间换热器7，最后在排风扇8的作用下排出排风管道。进入进风管道的新鲜冷空气先经过气体冷却器4，吸收了气体冷却器4中的二氧化碳工质放出的热量，新鲜冷空气的温度升高，然后再经过中间换热器7，吸收排出的污浊空气的热量，进一步地提高新鲜空气的温度，从而以适宜的温度进入隔离病房14。
以上所述的仅是本发明的优选实施方式，但本发明并不局限于上述的具体实施方式，对于本领域的普通技术人员来说，在不脱离本发明创造构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。
