Chilled water coils
Chilled water coils
(OP)
We know that it is usual practice to pipe chilled water to coils counter flow in respect to airflow. Another words the coldest water on the leaving air side of the coil.
Question, is there any documentation that dictates whether the supply and return should be high or low on the coil?

It is also good practice to have vent and drain connections at the high and low points on the coil to provide to getting rid of trapped air. These connections also allow for hydrotesting and draining of the coil at the factory. In any closed-loop system, there should be a surge tank at the high point in the system to allow for venting, too.
