So many areas where a little forethought and awareness can avoid larger problems — sizing, velocity, piping and connections, double trapping, condensate return, proper pressure, blowdown tanks, and more. Read on for some good habits and why they’re worth having.
When designing or replacing a low pressure steam boiler, throw out everything you know about hydronic boilers. A steam system is closer in operation to an air conditioning unit than it is to a hydronic boiler. If you design a steam system using hydronic design methods, it will not operate properly.
Leaning on experience and data from various K-12 cities and projects, the authors pursue some less conventional design approaches. They may revolve around radiant heating and/or cooling, but depending on school size and other factors, the smart use of heat recovery, DOAS, and improved central plants could also put a project on the HVAC honor roll.
When it comes to writing an important research paper, it’s essential to include references. That’s exactly what Tom Mangogna had his district engineering staff do when it came time to research using Daikin for their school district.
When Miller Bonded Inc. (MBI) decided to design its new pipe fabrication facility in Albuquerque, NM, the HVAC mechanical contractor not only wanted to streamline production, it also wanted an energy-efficient building.
When I got started in the HVAC business half a century ago, I was very fortunate to work for a small firm where I learned a lot about design engineering from some really knowledgeable and practical HVAC engineers. The business we were in was designing HVAC for hospitals, colleges, universities, research facilities, and museums. All of these facilities required very sophisticated central air systems, heating systems, and chilled water systems.
We’ve been working double time this month to produce not only the issue of ES before you now, but also the spring edition of Today’s Boiler. That is the official publication of the American Boiler Manufacturers Association, and it also gets a facelift as of this month, thanks to a redesign and the first phase of some editorial additions.
Look at not only some nearly automatic benefits-in-waiting for your average hospital boiler retrofit, but also at some ideas for what to do if there isn’t budget for a full replacement. Meanwhile, a short laundry list of hospital-specific boiler considerations actually includes the laundry (but not how you might expect).
The public’s taste for regional and local beer has flourished in recent years, but crafting a proper steam boiler system for its production can be sobering task. Pull up a bar stool and contemplate at least 23 design and maintenance facets to ensure that what’s brewing is all beer and no trouble.
Engineered Systems magazine’s April 2019 issue focuses on K-12 schools, showcasing how districts across the nation are using hybrid systems and advanced BAS systems to cut their energy use and costs, how kitchen ventilation systems should be installed and maintained, and more. The issue also examines the present and future of artificial intelligence in the built environment, one engineering firm’s advanced attempt to create a nonproprietary BMS system, and much more.
