空调师傅必备，各种制冷剂温度压力对照表大全

大家好，我是小泥巴，今天我们又要推出我们的福利了，今天给大家推出的是各种制冷剂的温度压力的查询，方便大家在检修、制冷系统分析的时候查询蒸发冷凝温度。

先给大家普及一些简单的估算方法：

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以及R410A温度压力对照表附给大家，

其他制冷剂请直接在公众号里回复就可以得到了。
