Description

一种用于新型高效全热交换式新风换气***的热能回收装置 技术领域
本发明属于新风换气设备领域，具体公开了一种用于新型高效全热交换式新风换气***的热能回收装置。
背景技术
新风***是根据在密闭的室内一侧用专用设备向室内送新风，再从另一侧由专用设备向室外排出，在室内会形成“新风流动场”，从而满足室内新风换气的需要。实施方案是：采用高风压、大流量风机、依靠机械强力由一侧向室内送风，由另一侧用专门设计的排风风机向室外排出的方式强迫在***内形成新风流动场。在送风的同时对进入室内的空气进过滤、消毒、杀菌、增氧、预热(冬天)。在冬天，新风***对于送入室内的空气一般通过电热丝加热，在寒冷的冬天，室内外的温差很大，对于空气的加热需要消耗大量的热能，同时由于新风***也要源源不断的从室内将浑浊的但是有温度的空气排出室外，这时候，相当多的热量就会损耗在排气过程中，目前虽然也有一些用于新风***的能量回收装置，但是普遍成本高而效率较低，无法获得满意的节能效果，甚至不能抵消增加的成本，导致应用推广困难。
发明内容
针对以上不足，本发明公开了一种用于新型高效全热交换式新风换气***的热能回收装置。
本发明的技术方案如下：

进一步的，上述一种用于新型高效全热交换式新风换气***的热能回收装置，所述微孔过滤板和所述储热陶瓷板的厚度均为2cm。
进一步的，上述一种用于新型高效全热交换式新风换气***的热能回收装置，所述微孔过滤板的孔径从新风进气口向新风排气口方向逐渐缩小，从100um到45um。
进一步的，上述一种用于新型高效全热交换式新风换气***的热能回收装置，所述浊风散热管的管径为1mm，数量为300根。
进一步的，上述一种用于新型高效全热交换式新风换气***的热能回收装置，所述浊风散热管为纯铜。
