Our Refrigerant Focus series consists of deep dives into the history, properties, and pros and cons of some of today’s common refrigerants. This installment will focus on R-454B.
At Super Radiator Coils, our mission is unleashing the power of thermodynamics to improve our world, and when it comes to the industries and applications we support, few fit that mission better than pollution control. Heat transfer is used for a litany of pollution control functions – from condensing harmful vapors out of exhaust streams to reducing or repurposing thermal energy from industrial process emissions to lessen its impact on the environment.
In our last article on hot gas reheat coils, we looked at the basic function of hot gas reheat coils and some common methods used to integrate them into a system. In this article, we'll look at some best practices when running hot gas reheat coil selections within Enterprise, SRC's coil selection software. For this exercise, we used a theoretical hot gas reheat coil to explain the coil selection process for hot gas reheat coils using the hot gas and parallel condensing methods.
Because of its rarity and the likelihood that the performance requirement can be met using one of the other configurations, we have not included selection best practices for the warm liquid method. But, if you find yourself working on an application that may be well suited for that approach, feel free to contact us directly and we’d be happy to take a look.
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.
In the world of commercial HVAC, efficiency is a critical measurement of a unit’s effectiveness, and one (of many) methods used to improve that metric is with a hot gas reheat coil. In this article, we’ll explain the function of a hot gas reheat coil and examine the various methods used to integrate them into a unit:
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.
In early October, Michael Regan, Administrator for the US Environmental Protection Agency signed the agency’s final rule, titled “Phasedown of Hydrofluorocarbons: Restrictions on the Use of Certain Hydrofluorocarbons under the American Innovation and Manufacturing Act of 2020.” The rule focuses primarily on the technology transition-related objectives of the AIM Act.
In some cases, a 5mm copper tube, aluminum fin coil is a more durable and versatile alternative to microchannel designs. At SRC, we can match microchannel performance with 5mm Cu/Al for predetermined dimensions and conditions. Check out the video below to see Ken Allen, SRC's Southeast Regional Sales Manager, walk through that process in Enterprise, SRC's coil selection software.
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.
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.
If you're in the market for heat exchangers, let's work together to get you just the right tool for the job.
