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.
In early February, the European Chemicals Agency (ECHA), an agency of the European Union, announced the introduction of 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 outlined by the ECHA.
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.
That’s a wrap! The 2023 AHR Expo has come and gone. Super Radiator had a very busy show and we enjoyed seeing all the innovation and excitement on display in Atlanta this week. For this post, we thought we’d share our perspective on our show – the hot topics and near-term industry outlook, the show itself, and some perspective from SRC’s attendees.
The US started limiting HFC usage on January 1st, 2022, following the passage of the American Innovation in Manufacturing (AIM) Act of December 2020. Prior to the legislation, the EPA did not have the authority to make changes to HFC usage, and HFC policy decisions fell largely to the states, 11 of which had already begun HFC phasedown measures under the US Climate Alliance. The EPA's current phasedown schedule is aiming to reduce the production and consumption of HFCs by 85% below baseline levels gradually by 2036. This means that individuals and organizations that currently use HFCs like R-404A, for example, have a decision to make.
