Self-Paced Learning

Engineers Newsletters & Engineers Newsletters Live!

Trane Engineers Newsletters are topical, informative articles that provide engineering professionals who design HVAC systems with reliable, objective, and technologically current information in a non-commercial format.

For 50 years, these newsletters have been published by Trane Applications Engineering group to aid engineers in the design and application of HVAC systems. Subjects range from acoustics to water piping to interpretation of ASHRAE standards. These newsletters have become a trusted technical resource, with a current circulation of more than 40,000.

Heating with Lower-Temperature Hot Water

Historically, many hot-water heating systems were designed for 180°F supply. Then, with the increased use of condensing boilers, many systems began to be designed for lower hot-water temperatures (e.g., 140°F) to increase boiler efficiency. Today, growing interest in decarbonization and electrification has increased the use of heat pumps or heat recovery for heating buildings; technologies that benefit from even lower hot-water temperatures. This EN examines how to select coils for these lower hot-water temperatures, in order to maximize the performance of these newer heating systems.

Refrigerants: 50 Years of the Engineers Newsletter
Hello Summer! The heat and humidity of the season is finally knocking on our door. This means that our heavy lemon juice consumption season is coming to sporting events, neighborhood fundraisers, and local festivals. Speaking of juice, in our July Engineer Newsletter Blog, we will quickly browse through our past newsletters and other literature on refrigerants, the so-called “magic juice” inside air conditioners.
Many of our past Engineers Newsletters can be found in the various topic sections below.
