Over the years of designing and building HVAC infrastructure, I’ve been fortunate to be able to complete the projects via integrated project delivery (IPD) and design-build (D-B), in addition to design-bid-build (DBB) and construction management (CM).
Evolving facility needs, revenue-generating special events, in-house labor, the deferred maintenance budget … the factors in a temporary HVAC decision range wider than you might think. So are the opportunities.
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.
In this section of our post-AHR/ASHRAE coverage, your intrepid editor traverses the carpeted hallways of Las Vegas, taking copious notes at gatherings to discuss two specific standards past, present, and possibly future.
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.
