750是什么意思(制冷剂温度压力对照表)
最后更新 ：2023-03-03 18:06:42
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、R23、R404A以及R410A温度压力对照表附给大家，
