Schwank is offering a PDH webinar next week for design engineers. The webinar covers how the new Schwank air curtains can save energy by keeping conditioned air in buildings when doors open.
So far, the US has won five gold medals in the PyeongChang Olympic games. You probably knew that. But, did you know that AERCO is supplying hot water to five out of the six main hotels at the 2018 XXIII Olympic Winter Games in South Korea? True story.
Take a sneak peak inside Griswold Controls' test lab! In 2017, Griswold re-engineered their lab space and are offering a sneak peak inside the place where their innovative valves undergo rigorous testing to ensure they'll work in the field.
I like to think that we're all getting smarter. After all, we have smart phones, smart homes and even smart cars. Even our HVAC equipment is getting smarter. Visit a modern mechanical room these days and you'll see brightly lit touchscreens, ready to interact with users. It's probably no big surprise that users can now control VFDs through their very own smartphone.
We talk a lot about continuing education here at Heat Transfer Sales. We want engineers, building owners and contractors to know about the new technology available to them. Saving time, money and energy are easier than ever these days with efficient systems. While traditional equipment may still have its place, these days, commercial building equipment is smarter than ever.
Building systems equipment is expensive. And when the temperatures dip below 40 degrees (F) or soar above 80 degrees (F), it’s important that your HVAC systems are running efficiently and safely for the comfort and health of all your building occupants.
I'm not saying you can get PDH credits for no effort, but there are some pretty easy (and often free) ways for professional engineers to earn PDH credits. These won't soak up too much of your time and, perhaps most important, you may learn something.
I’ve been in the commercial HVAC rep business for over 15 years now and have helped many people design and select boiler systems for their buildings. Yet, the sizing of these systems is most always derived from a load calculated by a mechanical engineer (which I am as well, by the way – see my other blog “Is Your Commercial Boiler System Oversized”). As we run into bitter-cold days here in the Carolinas, (what we in the engineering field call “Design Days”) I cannot help but wonder, how close were we in sizing these systems for actual conditions?
If you are a building owner or have designed systems for owners, on these really cold days, have you ever checked the boiler plant to see how it is running? On Design Days, which present the worst-case conditions your building should see throughout the year, is your boiler plant running at 100% capacity? If you have multiple boilers, are all of them firing at 100%? Are your variable speed pumps running at 60-Hz (100% speed)? And, if the answer is “Yes" or the answer is “No," is that a good thing? The point is to learn what we can about a system from this answer.
