Venting Air from a Closed Loop System

Venting Air from a Closed Loop System

Venting Air from a Closed Loop System

(OP)
In order to dry a network of piping following their drainage, we intend to use a dryer and blow air into piping by establishing a closed loop (to use a hose to connect end of the line to fan inlet). My question is: Can we-at one point along this loop- vent part of the air into another branch which itself vents to atmosphere and make up the lost air from loop by admitting o/a at dryer suction. Due to some constraints we cannot include this branch in the closed loop. By above arrangement the branch (line) can also be dried w/o using additional dryer.

Why not

RE: Venting Air from a Closed Loop System

If having a "closed loop" is important to you for some reason then no. You will no longer have a closed loop.

If having dry pipes is important to you then maybe. How much air will flow through each branch will be determined by the system curve of each branch.

You'll need to establish that you have enough flow through each.

RE: Venting Air from a Closed Loop System

Can't you just purge the lines with compressed air or nitrogen and blow out any water? Are you drying these lines to prevent corrosion during long periods where the system will be empty? Not sure how much airflow a fan will provide through small branch lines. You might need a high-static blower.

BronYrAur was onto it – use an inert gas like N2 or Argon. You can easily hook up a bottle of said substance to a fitting, bleed a remote end and prevent corrosion (which needs O2) altogether.
