2025年中国上海制冷展CR EXPO

2025-04-27-04-29

距离148

简单的估算方法:

如下:

冷凝温度=工况温度(空气温度/水温)+(8~18)℃

蒸发温度=工况温度(空气温度/水温)--(10~20)℃

举例:

如何判断制冷系统是否缺少冷媒?

很多人都说看系统的运行压力,但是新手基本上不知道怎么看;

很简单,比如现在室外温度大概35℃,房间设定温度27℃;那么根据上面的经验,得出:

冷凝温度=35+10=45℃;

蒸发温度=27-20=7℃;

当然这些是估值哦。

根据我们下面的列表,很快就可以得出压缩机运行的高低压了;

比如是R22冷媒的;

那么高低压就是:1.75Mpa左右;

低压就是:0.6Mpa左右。

如果低压低于这个值,那要考虑系统是否缺少冷媒了。

好了,下面我们把R22、R23、R404A以及R410A温度压力对照表附给大家,
