1. 基本空调全堵都会跳机. 后面再做一个小时是不堵风口的. ' r; \( m- T. i; m8 k$ I2.制热的时候你可以在室内测看室内机有没有滴水出来. 空调室外机结霜的话,一般会自动跳机除霜.不难判断. $ j& e0 y, `) Z& g/ t" A& nEN 的好象只能用热平衡或室内焓差室做? 太久没看这个标准都忘了... ; t' [- T% c# Z2 g( Y这个标准写得比较烂, 不如AS 3823.作者: yuanhao177 时间: 2008-1-23 12:58
全堵肯定跳机,跳机后TSE工程师要求堵着运行一小时,而后正常运行一小时。 ( [0 Q- e5 R9 N7 j欧标和美标都要求焓差室做,capacity可以在平衡室做,顺带做能耗! / M0 K# k9 E) C/ y t4 z# L i! X这个标准为客户指定的,着实郁闷,平时主要依照IEC来做!作者: sunshower 时间: 2009-5-21 06:37
我最近也是在搞EN14511试验,但由于英文较POOR,好多内容看不懂。不知楼主可有中文版本的14511呀?最近真是搞得焦头烂额了!求楼主帮忙。我的QQ21713223,EMAIL:SHAXUTZ@163.COM,先谢了。
