Re: Explosion in the NH3 system
Hello phananhtuen
I think it's problem can be found in blocking cold liquid.
In a 2 stage system there is most of the time verry cold liquid -30 degrees.
When the system stops and non return valves are installed wrong you can have -30 degrees liquid blocked in.When the liquid temperature rises the pressure will rise in an absurd pase.It is just like freezing water there is no way we cab build something that can resist that kind of pressure so things will break wich may sound and can look like explosions.
Kind regards Art
