/By Chris Edmondson
Air must be managed in every type of closed hydronic system, either by (1) routing it to a specific place in the system where it can’t create problems like pipe corrosion or air blocking of components, or (2) by continuously eliminating it
Air Management and Pressurization Part 1 - The Rationale Behind Closed System Design
/Closed loop systems create the need for accurate pressurization and air management in a hydronic heating and cooling system. Unfortunately, proper air management often turns out to be an Achilles’ heel in a hydronic system’s design. Design it wrong and a host of problems can erupt, from noisy operation to poor efficiency and shortened equipment life. It begs the question -- why even design a system to be closed in the first place? After all, condensate systems and cooling tower systems are

/What are the pump affinity laws and why are they so important?
Pump affinity laws define the mathematical relationship that exists between pump speed, flow, total head, and power consumption.
ASHRAE Pipe Sizing Requirements Are Changing – System Syzer Makes It Easy!
/Bell & Gossett’s System Syzer does all the piping calculations necessary to meet ASHRAE 90.1 and 189.1 requirements. JMP is committed to getting all our customers up-to-speed on ASHRAE 90.1 – 2010. We’ve already covered some of these topics in previous blogs, including changes to pressure booster design. Today’s blog focuses on the portions of 90.1 - 2010 that dramatically impact the selection of pumps and associated piping.
