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.
Years after an HVAC engineer starts to design closed-loop water systems and then progressively moves up the ladder of engineering success, he can forget and/or overlook many of the issues, concerns, details, opportunities, etc. associated with engineering these systems.
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.
Creating a better indoor environment sometimes takes a revolutionary step and a new way of thinking. The HVACR industry shows no signs of resting on its laurels as the need for greater energy efficiency, IAQ, and sustainability continues to grow. Engineered Systems asked some the winners of the AHR Expo Innovation Awards winners about current trends and what the future of technology looks like.
Warm discharge plumes sweeping back into air-cooled condensers is nobody’s idea of an ideal performance environment. This CFD study shows how wind speed, wind direction, spacing between chillers, and separation from adjacent buildings all factor into the conversation about the best defense against unwanted hot air.
Now that many of us are back from the annual ASHRAE and AHR Expo conference, our minds may be jangling from having seen an array of innovative technologies utilizing the cloud, smartphones, and demand automation.
