R-454B Performance vs. R-410A: Capacity & COP (WEBINAR CLIP)

Posted by Super Radiator Coils on Jun 12, 2024 3:42:54 PM

Capacity and coefficient of performance (COP) are both used to measure HVAC equipment's effectiveness, but they tell different stories. Capacity, measured in tonnage or Btu./hr., refers to a unit's ability to heat or cool a space. COP measures efficiency - the relationship between a system's performance and the cost of the electricity needed to power it. To many - especially those in the commercial HVAC market - COP is the more consequential metric due to its direct impact on the operating costs for unit manufacturers' customers.

But for OEMs that have opted for R-454B as their replacement for R-410A units, there are some interesting performance implications associated with making that switch. Specifically, R-454B typically offers better COP, but based on our recent performance testing, there are scenarios in which its capacity is less than R-410A.

Understanding Temperature Glide in Blended Refrigerants (WEBINAR CLIP)

Posted by Super Radiator Coils on Jun 5, 2024 11:39:00 AM

Zeotropic refrigerant blends have become more prevalent than ever, as regulation has pushed the HVAC-R and related industries away from single-component fluids as well as popular azeotropic* blends like R-410A. But with zeotropic mixtures comes temperature glide, an in-depth understanding of which can help you be sure that your performance calculations are as accurate as possible when designing a unit or system.

What is an Evaporator? Function, Features, & Design Considerations

Posted by Super Radiator Coils on May 7, 2024 9:08:04 AM

The evaporator coil is a critical part of any compression-expansion refrigeration cycle and is one of at least two heat exchangers used to capture and direct thermal energy for useful purposes in such systems. This article will cover some fundamentals of evaporator coils – their function, componentry, and some information on how to best design them to ensure proper function.

Heat Pump Coil Selection Best Practices (VIDEO)

Posted by Super Radiator Coils on Mar 21, 2024 8:38:48 AM

Unlike standard air conditioning or heating systems, heat pumps have the ability to serve both functions. Because of that, the coil selection process for heat pumps differs somewhat from non-heat pump designs. Check out our latest video to learn more about some best practices when running heat pump coil selections in Enterprise, Super Radiator's coil selection software, so you can be sure your coils perform as needed in both heating and cooling modes.

What is a Condenser Coil? Function, Features and Design Considerations

Posted by Super Radiator Coils on Mar 12, 2024 8:25:32 AM

In any compression-expansion refrigeration cycle, there are (at least) two heat exchangers working in tandem to condition a space, one of which is the condenser coil. In basic terms, the function of the condenser coil is to take the heat absorbed by the system’s evaporator and move it away from the space being conditioned.

In this article, we’ll expand on the condenser coil’s function, look at some typical condenser coil configurations, and finish by discussing some design considerations for common condenser applications.

AHR Expo 2024: Recap & Reflections

Posted by Super Radiator Coils on Feb 6, 2024 11:03:22 AM


Well, that’s a wrap. Another AHR Expo is in the books, and we thought we’d check in with some SRC employees who attended the event to hear what they thought of the show, how it compared to previous years, and some market dynamics and ‘hot topics’ that they heard discussed during their time in Chicago.

AHR Expo 2024 – Expectations, Goals, and Predictions from the Super Radiator Coils Team | Super Radiator Coils

Posted by Super Radiator Coils on Jan 16, 2024 9:43:09 AM

Well, that time of year is upon us once again. For folks in the HVAC-R world, the start of a new year means it will soon be time for the AHR Expo, the largest trade show and networking event in the HVAC-R and related industries. We exhibit at the show every year (Booth #S6964 – come see us!) and send a group of SRC employees to man our booth, catch up with customers and vendors, learn about new products and technologies, and much more.

Each year, SRC's representatives consist of both longtime veterans of the show as well as those attending for the first time, and our AHR team this year is no exception. We connected with some of the SRC team members who will be attending the event to learn more about what they hope to do, see, and learn at AHR 2024.

CO2 & Refrigerated Display Case Applications (PODCAST CLIP)

Posted by Super Radiator Coils on Apr 26, 2023 3:24:27 PM

Our recent podcast, Emerging and Potential HVAC-R Applications for CO2, explored some uses for CO2 in refrigeration and HVAC applications that we've been keeping our eye on and some that we think have the potential for widespread adoption in the industry. One application that is gaining traction in the US is the use of CO2 for refrigerated display cases. Listen to the clip below to hear what Ken Allen, SRC's Southeast Regional Sales Manager, has to say about CO2's potential as a refrigerant in that market.
