Interlaced circuiting of heat exchanger tubes is an effective way to make heat transfer equipment more versatile and adaptable to variable conditions. But, in my experience, industry knowledge of interlaced circuiting’s impact on coil performance at different load conditions is often overly conservative or incomplete. This article will cover the following topics:

Super Radiator Coils has completed the first in a series of wind tunnel tests designed to understand how changes in an A-frame coil’s angle impact air friction. This post will explain that research, including:

• Background
• Testing methodology
• Conclusion
• What’s next?

We’re super excited to announce that we’ve validated the performance ratings for R-449A and R-448A condensers in Enterprise, our coil selection software. We believe the condenser coil performance model we’ve developed is the most comprehensive and accurate of its kind in the industry.

We wanted to use this post to briefly explain our testing methodology to our users. We’ll also touch on why performance modeling for these refrigerants has been challenging in the past, and how we plan to improve our model over time.

This post summarizes the design and results from a set of tests recently conducted at Super Radiator Coils.

Plate fin-tube heat exchangers are widely used in many residential, commercial, and industrial systems, such as HVAC, food freezing/drying, data center cooling, heat recovery, dehumidification, etc.
