Sample interview questions: How do you approach system water balancing and flow adjustments in hydronic applications?

Sample answer:

System Water Balancing and Flow Adjustments Approach

1. Analyze System Design and Requirements: Study the system drawings, specifications, and equipment data to understand the intended flows and temperature distribution. Determine the desired pressure drops and flow rates for each zone.

2. Set Reference Pressure and Flow: Establish a reference point by setting the supply pressure at the boiler or heat exchanger to the specified value. Use differential pressure gauges to measure the pressure drop across the system and adjust the flow rate to match the design specifications.

3. Zone Balancing: Divide the system into individual zones and adjust the flow to each zone using balancing valves. Start by closing all balancing valves except the one for the zone with the lowest pressure drop. Open the valve until the pressure drop reaches the desired value.

4. Flow Diverters: Use flow diverters to redirect a portion of t… Read full answer
