BAS integration to other BAS or to controls provided with mechanical/electrical equipment (“Factory Mounted Controls” or “FMCs”) was a driving force behind the development of BACnet.
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.
Engineers who pull out the 2015 ASHRAE Handbook HVAC Applications or 2016 HVAC System and Equipment Handbook will not find the topic of temporary HVAC systems.
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.
For those who design in BIM/CAD, manufacturer-provided content is widely viewed as being superior to generic, out-of-the box content when planning and designing a project.
Two Roads Brewing Company in Stratford, CT, was looking to expand its fast-growing brewery and needed the expertise of an HVACR manufacturer to assist them.
The town of Portsmouth, RI, had four schools (two elementary schools, one middle school, and one high school) with outdated, inefficient gas-fired hot water boilers that were becoming expensive to maintain and operate.
Budget woes. Equipment that has outlived its effectiveness. Unorthodox original decisions and little space to maneuver. The layers are many, but as this project shows, the solutions are there.
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.
Our objective in specifying motors for HVACR equipment is to start and run the driven equipment under all operating conditions reliably and with reasonable life expectancy.
