In this Engineers Newsletter LIVE (ENL) program, we delve into how heat-recovery chillers, heat pumps, and chiller-heaters can be configured and controlled in a hydronic system to provide heat efficiently.

We also cover the impact of hot-water and outdoor-air temperatures on the capacity and efficiency of the system, methods to simplify the design and operation of the system, and the importance of ensuring building operators and facility managers can operate the system as intended. The goal is to reduce environmental emissions and make the system as simple as possible, but not simpler.

This ENL features applications engineers Dan Gentry, Sarah Hilden, and Mick Schwedler. After viewing this program, you should be able to:

• Comprehend the difference between decarbonization and electrification of heat
• Understand the direct environmental impact of refrigerant choice
• Recognize the impact of source and hot-water temperatures on energy and capacity
• Appreciate the differences between traditional chilled-water system design and designs used to electrify buildings

More about Trane Engineers Newsletter LIVE (ENL) programs

Trane ENL program is a series of video programs focused on the design and control of HVAC systems, industry issues (sustainability, decarbonization, indoor air quality, acoustics, etc.), or codes and standards. The content is technical and educational, but non-commercial. The target audience is HVAC system design engineers; however, some programs may also be of interest to others in the industry.

Previous programs are available to view on-demand, and free of charge, in the Trane Education Center. In many states, ENL programs meet the requirements for earning Professional Development Hours (PDHs) to help meet the continuing education requirements of your professional engineer license or other certification.
