Volume of Chilled Water in the System
Greetings to all,
Kindly advise how to calculate the volume of chilled water to fill inside the closed circuit. Is it the same as internal volume of the pipe?

Well, yes...
+ The internal volume of all the equipment attached to it, like chillers/fan coils/expansion vessels and so on.

If you have an expansion/ make-up tank, make sure that it is also full with water.Keep an eye on the tank while charging the whole circuit with water.Air locking is a critical issue occurs when we charge the empty lines.Hence make sure you have air purging valves on the CHW lines or provide the appropriate points to remove the air from the system.If we charge the system with proper care, we can prevent the problems related to air locking.
