Retrieving every last bit of performance from the system while stopping short of the surge line is no small feat. Dig into sizing, tower selection, chilled water loads and stability, and condenser water management to leave no efficiency stone unturned.
Finding the holy grail of centrifugal chiller optimization for all operating conditions is hard, if not impossible. This article will talk about the requirements of most chiller systems and means of control for condenser optimization.
For years, architects have benefited from having readily available manufacturer content at their fingertips. Now it’s time for MEP engineers to start experiencing the same benefits, especially when it comes to designing with crosslinked polyethylene pipe.
In the first of a pair of articles on motor fundamentals for HVACR, the author gets into everything from industry standards and service conditions to changing speeds, enclosures, and the often misunderstood service factor. You’ll want to save this one for your team’s reference library.
We’re trying something different this year. Finding ourselves yet again unable to bend the time-space continuum so we could give you print coverage of the AHR Expo and winter ASHRAE meeting in February’s issue, we decided to go ahead and serve up two features of more in-depth coverage in March.
Years after an HVAC engineer starts to design closed-loop water systems and then progressively moves up the ladder of engineering success, he can forget and/or overlook many of the issues, concerns, details, opportunities, etc. associated with engineering these systems.
Why was one floor’s laboratory ventilation failing to keep up, when it was even the closest floor to the rooftop fans? Some system sleuthing led two engineers to a fitting conclusion. Read more stories in May Issue 2017.
