Terminal Systems-Reviving IEQ!

For the decades prior to the COVID-19 pandemic, comfort and energy efficiency seemed to eclipse indoor environmental quality. However, going forward, all elements of indoor environmental quality will likely remain important, along with energy efficiency. At the same time, terminal systems coupled with a separate ventilation system are growing in popularity.

Trane Engineers Newsletter Live

The year 2022 marks the 50-year anniversary of Trane’s Engineers Newsletter (EN) publication. This year, in addition to our quarterly topical newsletter publications, we’re going to highlight past newsletter topics as they relate to current issues and showcase past and current authors. 



DX Systems: 50 Years of the Engineers Newsletter
It is June and we are half-way through our Engineers Newsletter 50th anniversary celebration! As the temperature and humidity begin to rise, our appreciation for air-cooling equipment increases. One of the most prevalent cooling systems applied in our homes and small buildings are direct expansion (DX) split systems. Over the years, seven percent of the Engineering Newsletters have covered topics involving split systems. According to one EN, a split-system is nothing more than a packaged unit split in half, one half staying on the roof and the other half moved indoors into a central station air handler. While this is not always the case, it is a good place to start.
Many of our past Engineers Newsletters can be found in the various topic sections below.
