CO2's Versatility (PODCAST CLIP)

Posted by Super Radiator Coils on Mar 10, 2023 8:40:56 AM

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. There are a number of applications that could eventually fit that description, and one of the reasons for that varied potential is the versatility of CO2 as a refrigerant. Listen to the clip below to hear what Ken Allen, SRC's Southeast Regional Sales Manager, has to say about CO2's applicability for multiple HVAC-R functions.

EU Weighs PFAS Ban, Would Impact Refrigerants

Posted by Super Radiator Coils on Mar 1, 2023 9:35:59 AM

In early February, the European Chemicals Agency (ECHA), an agency of the European Union, announced the introduction a proposal aimed at restricting the production and use of per-and polyfluoroalkyl substances, commonly referred to as PFAS, across the EU. In this article, we’ll explain some background on the proposal, define PFAS & touch on some included substances with relevance to the HVAC-R industry, and go through the proposal’s next steps as outline by the ECHA.

CO2 Pressures & Properties (PODCAST CLIP)

Posted by Super Radiator Coils on Feb 28, 2023 8:56:36 AM

Interest in CO2 as a refrigerant for HVAC-R applications in the United States has increased substantially in the past 10 years or so. As new technology emerges seeking to capitalize on CO2's near-zero global warming potential (GWP), we wanted to hear what one SRC's CO2 experts thought about the practicality of some newer applications for the refrigerant. The conversation below is a clip from a larger discussion around the long-term viability of some emerging and potential HVAC-R applications for CO2, a.k.a. R-744. Listen to hear some comments from SRC's Southeast Regional Sales Manager Ken Allen on the pressures of CO2 and some other properties.

Coil Circuiting Best Practices (Fluid Coils)

Posted by Super Radiator Coils on Dec 6, 2022 9:38:53 AM

In heat exchangers, circuiting refers to the pattern by which the working fluid travels from the coil’s supply to its return. Also relating to coil circuiting is the orientation in which the coil is installed, relative to the direction of the application’s airflow.

Coil circuiting and its relationship with the application’s airflow are critical considerations of coil design, as proper circuiting can help increase the heat transfer coefficient of the heat exchanger.

On the other hand, improper circuiting can lessen a coil’s effectiveness and even cause damage, like tube erosion resulting from insufficient calculations for fluid velocity, for example. So, it’s important to understand the forces at play before deciding on a circuiting layout.

ATMOsphere America Summit 2022 - SRC Takeaways

Posted by Super Radiator Coils on Jun 27, 2022 11:18:08 AM

Studying the performance of refrigerants is of our passions at SRC and we've invested heavily in learning as much as we can about them. Last week, ATMOsphere held their annual natural refrigerants conference in Washington D.C. The conference took place on June 7th and 8th and Super Radiator Coils sent three engineers to learn about the natural refrigerant market, emerging applications, new technologies, and more. Read below to hear what SRC's Ken Allen, Will Klick, and Gail Miller took away from the conference and their thoughts on the future of natural refrigerants.

CO2 Properties, Best Practices & Benefits [Transcript]

Posted by Super Radiator Coils on Jun 14, 2022 9:36:37 AM

Note: the following is a transcript of a podcast. To listen, check out the SRC Podcast here or wherever you get your podcasts. 

Nate Budryk: Hello and welcome to another SRC podcast. Today, we’re talking about one of the poster children of the natural refrigerant push, which is CO2, also known as R744 or carbon dioxide. Today’s conversation will include a brief overview of CO2, some specifics of the refrigerant & CO2 systems, and some industry general best practices. To help us do that today are two CO2 experts: Will Klick, who serves as sales application engineer for SRC, and Wynand Groenewald, a director at Future Green Now, which is a CO2 consultancy based in South Africa. Will and Wynand, how are you doing, guys?
