Appropriately enough, a good variable airflow design accommodates and refines a number of design variables. Particle monitoring strategies, minimum supply air calculation, HVAC sequencing, and space pressurization are just a few stops on the way to spotless performance.
Here’s a good reference for facilities, TAB pros, or even commissioning agents on what should be found on site (and how to achieve it in the first place). For install through setup, properly managing connections, bearings, controllers, and vibration risks will create an air of success.
Patrick Baldwin-McCurdy fields daily indoor air temperature requests from employees and students, but Seattle University’s (SU) lead buildings control technician rarely hears HVAC complaints from the college’s new library addition featuring under floor air distribution (UFAD).
Effective building envelope and air handling designs took comfort most of the way from theory to reality in ISU’s Hach Hall. An existing in-house deionized water supply and a new fogging system finished the task and saved an estimated 22% in humidification costs.
In this column, I will describe the “issue” disclosed through analysis of the trend graph included in my January 2012 column. I will also introduce a new system and show its trend graph, leaving it up to the reader to discover the operational “issue” illustrated in the graph. The answer will be given at the start of next month’s column.
The middle of Oregon’s wine country is an unlikely setting for the campus of a world-class aviation museum, housing the Howard Hughes “Spruce Goose” and many historic aircraft. Even more unlikely is finding an Innovent custom air handler nestled under the fuselage of a B747 airliner, which sits atop the roof of a lively waterpark.
Andy Cummings of Southland Industries has suffered through his share of cumbersome damper actuator installs. With over 30 years of experience in the sheet metal industry, he knows that the process is not only time-consuming, it can yield disappointing results if the connections are in any way unstable.
So Charles Dickens, Ferris Bueller, a chicken, and a pig walk into an HVAC article … and try to sort out proper use of outdoor air in data centers. As you might imagine, it’s not simple. But if you remember these three design absolutes and consider your client’s specific perspective, the resulting efficiencies might have you singing Wayne Newton at the prospect of repeat business.
During the first two days of May 2010, a nearly 14-in. downpour fell on “Music City USA” and the Cumberland River burst its banks, causing the worst flood in Nashville’s history. Among the many businesses that suffered terrible losses during the flood was Schermerhorn Symphony Center, completed just four years earlier and home of the Nashville Symphony.
